一个铸件必须经过许多工序才能完成，从各种原材料准备开始，直到造型、制芯、合箱、浇注、落砂及清理为止，整个工艺过程都实行科学的操作，才能有效的控制铸件的形成，达到优质高产的效果。

铸件在生产之前，首先应编制出控制该铸件生产工艺过程的技术文件，称为铸造工艺设计。

铸造工艺设计是生产的指导性文件，因此，铸造工艺设计的好坏，对铸件的质量、生产率及成本起着很大的作用。

材料成型铸造专业毕业设计英文文献原文Casting and its processes1.1IntroductionManufacturing process can be classified into two general groups known as primary and secondary processes. The primary processes, namely, casting, forging, cold heading, cold extruding, brake forming, and so on, are those that convert raw material into shapes. These forming methods include both hot and cold working processes and, in general, will still require further finishing operations in order to obtain an end product.The secondary processes are those that bring the part to the dimensions and surface finish specified. One may also include in the secondary processes such operations as heat treating and surface treatments for corrosion resistance, hardness, and appearance. Secondary processes are planning , turning ,milling, drilling , boring , reaming , broaching , grinding , honing ,lapping , polishing , and special methods of metal removal such as electrochemical machining. Operations like screw cutting, tapping, thread milling, gear cutting, and so on ,are secondary processes that are merely adaptations of one of the aforementioned processes that are merely adaption of one of the aforementioned processes.A complete discussion of these procedures is beyond the scope of this text. Therefore, we will confine ourselves to succinct descriptions of the most prominent techniques.1.2 CastingsCastings are identified by the type of mold or the force required toy fill the mold. Molds are either permanent or expendable. The pattern of sand, shell, and plaster molds,however, can be used repeatedly for making new molds. As the metal cools, it takes the shape of the cavity. The basic casting methods are described below.Sand castings.1. The green sand process is one in which most, bonded sands packed around a wood or metal pattern. The pattern is then removed and molten metal is poured into the cavity .When the metal solidifies, the mold is broken and the casting is removed . Almost any metal can be used, with virtually no limit as to the size or shape of the part . The method permits casting complex components at a low tooling cost and is the most direct route from pattern to casting .Some machining is always necessary with the green sand process, and large castings have rough surface finish .Close tolerances are difficult to achieve, and long, thin projections should not be cast. It is possible , however , to design for bosses, undercuts and inserts .The minimum core hole diameter advisable are aluminum,3| 16—1|4 in. ;and the minimum section thicknesses advisable are aluminum ,3|16 in .;cooper , 3|32 in .; iron ,3|32 in .; magnesium,5|332 in ;and steel , 1|4—1|2 in .2. The dry sand process is similar to the green sand process except that core boxes are used inplace of patterns .This method is usually limited to smaller parts than method 1. The sand is bonded with a setting binder, and the core is then oven baked at 300—400 to remove the moisture.3.The carben dioxide sand process is one in which the sand molds are bonded whit sodium silicate solutions and set by forcing carbon dioxide gas through the sand .This type of mold is strong and permits the production of better dimensionallycontrolled castings than either method 1 or 2 .4 .The core—sand mold process is one where the molds are put together completely from oven baked cores set with organic binders such as oil or dextrines.Shell Mold Casting . This is a process where the molds are made by coating the sand with a thermosetting plastic .The mold is then supported on the outsaid by sand or shot, and molten metal is poured .When the metal has solidified , the mold is broken away from the finished casting. Shell molding produces casting with smooth surfaces, uniform grain structure ,high dimensional accuracy , rapid production rate and minimal amount of finishing operations . The minimum section thickniss castable is 1|16—1|4 in .but section differences where the maximum –minimum ratio is greater than 5 to 1 should be avoided. Bosses, undercuts and inserts are easily cast and the minimum cored hole diameter is 1|8—1|4 in .The method is relatively costly is limited to few metals.Full-Mold Casting .A process in which a green sand or cold-setting resin bonded is packed around a foamed plastic pattern (for example ,polystyrene ).The plastic pattern is vaporized with the pouring of the molten metal into the mold .An improved casting surface can be obtained by putting a refractory type of coating on the pattern surface before sand packing .The pattern can be one piece or several pieces , depending upon the complexity of the part to be cast .The plastic patterns are handled easily . They do not require any draft ,and produce no flash on the casting . For small quantity production this method can be expensive, depending upon the size and complexity of the casting .The minimum recommended section thickness is 0 .1 in .,and the maximum section thicknessis unlimited .Bosses, undercuts , and inserts present no problem in this type of casting . The minimum cored hole diameter is 1|4 in.Permanent Mold Castings .These are formed by a mold that can be used repeatedly . Some applications have reported as many as 25 000 castings being made from the same mold .Usually , the mold requires some redressing after about 3000 uses . The molds are machined of metal (for example ,gray iron ) for casting nonferrous metals and cast itons . Machined graphite molds are used to cast steel.This method produces castings that have a good surface finish as well as a good grain structure ,low porosity ,and high dimensional accuracy .The initial mold cost is relatively expensive, but castings weighing as little as several ounces to castings are limited to relativelysimple shapes and forms. The maximum recommended section thickness is about 2.0 in .The minimum thickness , however ,dependsuoon the material being cast as follows :3|16 in .for iton ,3|32—1|8 in .for aluminum, 5|32 in .for magnesium, and 3|32 –5|16 in .for copper .The minimum castable holes are 3|16—1|4 in .in diameter.Die Casting .A process used extensively in the quantity production of intricately shaped zinc, alumimum, lead and magnesium alloys .The method is limited in use with tin and copper alloys.Castings are formed by forcing molten metal under pressures of 1500-25 000 psi into an accurately machined steel die .The steel die ,which is water cooled ,is held together by a hydraulic press until the metal casting(s) solidifies., To ease the ejection of the cast parts, a lubricant is sprayed on the dieforming surface and the ejection pins. For small die cast components .,multiple cavity dies are used .The surface finish of the resulting castings is quite smooth and has excellent dimensional accuracy .Although the cost of production is relatively cheap ,the initial die cost is high .Diecasting is limited to nonferrous metals and by the size of the part that can be cast .The maximum wall section thickness is usually restricted to 3|16 in . but certainly to no greater than 0.50 in.Plaster Mold Casting .These are made by pouring a nonferrous alloy (for example , aluminum ,copper ,or zinc alloy ) into a plaster mold ,which is then broken to remove the solidified casting . The castings produced by this process are smooth, have high dimensional accuracy, low porosity, and can be made in many intricate shapes. The method, however, has disadvantages in that is limited to nonferrous metals, small castings and also requires a relatively long time to make the molds. The minimum wall section thickness is 0.040-0.060 in . for a cast area that is less than 2 sq .in . For larger cast areas ,the minimum wall thickness increased accordingly .The show process, developed within the last decade, is a cost promising method .It employs the use of plaster molds .This procedure produces castings with fine detail and excellent dimensional accuracy and surface finish.Ceramic Mold Casting . This process uses a mold made of a ceramic powder ,binder ,and gelling agent. The mold can also be made of a ceramic facing reinforced with a sand backing .The method is restricted to casting intricate parts requiring fine detail ,close tolerances ,and smooth finishes .The minimum wall thickness recommended is 0.025-0.050 in. There is, however, nolimit to the maximum wall thickness.Investment Casting. These are made when parts are desired that are intricate in shape ,have excellent surface finish , and require a high degree of dimensional accuracy .In addition ,this method of casting permits the use of a variety of metal alloys and does not have In addition ,this method of casting permits the use of a variety of metal alloys and does not have any metal flashing to be removed from the finishes casting.The technique of investment casting requires careful workmanship and expensive patterns and moths. The minimum castable wall thickness is about 0.025-0.050 in .and the maximum thickness should not exceed 3 in .Centrifugal Casting . This is a method of casting a shape by pouting the molten metal into a rotating fladk containing the mold .The molds are made of sand ,metal ,or graphite (depending on the metal cast ) and are rotated about their axial centers either in a horizontal or vertical position . Relatively large diameter and bulky components are made are pipe ,gun barrels, hollow shafts ,machinery drive rolls, long sleeves , tubing , and so on .Where the diameter to length ratio is rather large ,the rotational axis can be vertically mounted molds ,the method is called semmicentrifugal casting ,and it is used to make parts such as wheels, turbosupercharger diaphragms , disks ,flywheels ,and so on .Figure 1-5-2 shows a schematic section of a semicentrifugal casting of a cored flywheel .Generally, the method of centrifugal casting is expensive and is also limited in the shapes which can be cast .However ,the castings made by this mehod are very sound and have good dimensional accuracy .It should also be noted that this method is the only way to obtain a large cylindrical part.Continuous Casting.This is a method whereby a molten metal is continuously gravity fed from a ladle into an ingot mold of a desired shape which is open at both ends. As the metal ―falls‖through the mold , it takes its shape ,and is rapidly cooled by a water spray .It is then cut to specific lengths.The continuous casting process has the advantage of being low in cost and having a high rate of production .In addition, this method permits casting materials that cannot be extruded. However, continuous casting is restricted to shapes of uniform cross section (that is ,in the direction of casting),The minimum wall thickness depends on the shape being cast . The minimum size of casting is 1|2 in .and the maximum size is about 9 in .。

1305×570×555mm 。本次铸造采用重力铸造。所给图为零件图无加工余量，主要设计思 路：先用三维软件（ug）画出三维铸件图，然后确定其型芯结构、位置和大小、分型面 和分模面、浇注位置、铸造缩率等相关参数。选铸件侧面模流线做分型面，呋喃树脂砂 做为砂型，采用三个内型芯造型；根据铸件的重量及相关参数计算出浇注时间 38s，采 用中注式浇注方式，根据初步的铸造工艺设计，采用铸造 CAE，模拟凝固过程中铸件的 热节和缩松倾向，通过加 7 块冷铁进补缩，消除缩松。根据铸造工艺手册及其相关参考 文献，设计铸件的浇注系统，基于全封闭浇注系统的设计方法，设计直浇道、横浇道以 及内浇道的尺寸和摆设方案；生产批量为大批量，铸型采用一箱一件。接着观察该铸件 的充型和凝固过程，对铸件凝固过程和流动过程进行计算分析，并验证浇注系统设计。 最后将所有的设计工艺做出工艺卡画出工艺设计图的形式来表达出来。

Injection chamber casting process design
Abstract: I designed parts for the injection chamber, the material is QT400-18, casting net weight 1009g, size 1305 × 570 × 555mm. The casting gravity casting. The picture shows the parts diagram given no allowance, the main design ideas: first with a three-dimensional software (ug) to draw three-dimensional diagram cast, and then determine its core structure, Position and size of sub-surface and sub-surface mold, pouring position, casting shrinkage and other relevant parameters. Selected side casting mold parting surface flow lines do, furan resin sand as sand, using three inner core modeling; based on the weight of castings and related parameters to calculate the pouring time 38s, using the gating mode, according to preliminary casting process design, casting CAE, simulation of solidification process of casting and hot section shrinkage tendency, by adding seven cold iron tonic contraction, eliminate shrinkage. According to the manual casting process and related references, casting gating system design, design method based on closed gating system design sprue, runner and runner size and display scheme; production volume for high-volume, casting a type with a box. Then observe the filling and solidification of the casting process, the casting process and solidification process flow analysis to calculate and verify gating system design. Finally, all of the design process to make the process shown in the form of process card design to express it. Keywords: injection cavity; casting process;Analysis and simulation
