模具设计规范及要点模具设计是制造业中非常重要的环节,它直接影响到产品的质量和生产效率。
为了确保模具设计的准确性和合理性,制定一系列的规范是非常必要的。
本文将介绍模具设计的规范及其要点。
一、模具设计规范的目的模具设计规范的目的是确保模具具备高质量和高效率的生产能力,并最大限度地减少模具使用过程中的故障和损耗。
通过遵守规范,可以提高模具的使用寿命,减少维修和更换成本,提高生产效率,降低生产成本,提升产品的质量。
二、模具设计规范的要点1.模具设计应符合产品的要求:模具设计必须根据产品的尺寸、形状、材料和数量要求来进行,确保模具可以完美地制造出符合产品要求的零件。
2.模具设计应考虑材料的选择和加工工艺:模具所选材料应具有足够的强度和硬度,以承受生产过程中的高负荷和磨损。
同时,模具的加工工艺应考虑到成本、时间和质量的平衡,确保成型过程的高效和精确。
3.模具设计应遵循安全和可靠性的原则:模具的设计应确保操作过程中的安全性,尽量减少操作人员的伤害和事故发生。
同时,模具的设计要保证其可靠性,能够稳定地工作,并且容易进行维护和修复。
4.模具设计应考虑到工装和夹具的需要:在模具设计过程中,应充分考虑到工装和夹具的配套需求,确保模具能够与其完美配合,提高生产效率和产品质量。
5.模具设计应简化结构:模具的设计应尽量简洁,避免复杂的结构,以减少制造成本和使用成本。
同时,简化结构也有利于操作和维护。
6.模具设计应具备可拆卸性:模具的设计应尽量满足零部件的可拆卸性,使得维护和更换变得容易。
这样可以减少停机时间,提高生产效率。
7.模具设计应合理确定尺寸公差:模具的设计应根据产品的尺寸要求合理确定公差,以确保模具制造出来的零件尺寸准确且符合要求。
8.模具设计应注意冷却系统的布置:模具的冷却系统设计应合理布置,以确保零件的快速冷却和缩短生产周期。
冷却系统的设计也要考虑到冷却介质的供应和排放。
9.模具设计应充分考虑排气和出渣:模具的设计应考虑到充分的排气和出渣,以防止铸件中产生气孔和杂质。
模具设计规范不正确的浇口位置浇口位置对流动熔料前沿的形状和保压压力的效果都起着决定性作用,因此也决定了模制零件的强度和其它性能。
鉴于浇口的位置通常是同注塑零件设计人员和模具设计人员指定的,因此本文特别为这些人员而撰写。
不过,注塑加工厂商也应从计划阶段开始参与,以避免出现那些可以预见的问题。
浇口位置不当可能导致的不利影响半晶质工程聚合物制成的零件即使设计正确,但如果浇口位置不正确,其性能也可能遭到破坏。
无论是增强型树脂还是非增强型树脂,以下症状都明显说明了其性能受到影响:流动熔料前沿形状导致的熔合线和空气气穴都可能影响零件的外观,特别是增强纤维材料,其机械性能将会受到影向。
更改加工条件对这些影响也是无济于事。
如果浇口设在模制件的较薄部分,厚壁的部分会形成收缩痕迹和空隙。
尽管厚壁部分需要更长的保压时间,但由于材料在薄壁部分结晶较快(图1),厚壁部分将不再有熔料供应。
结果是,除了会产生光学和机械问题之外,还会在厚壁区域增大收缩量,在非增强型塑料中甚至会导致翘曲变形。
如果浇口过少并且位置不当,熔料的流动距离可能过长以及注射填充压力过高。
若模具锁定力不足,或者所使用的聚合物粘度低并且结晶速度过慢,这种情况可能导致飞边的增加。
另外,加工工艺“窗口”受到很大限制,因此不再能够通过模制条件微调误差。
最佳浇口位置建议★必须将浇口设计在壁厚最大的区域。
★浇口不能设在高应力区域附近。
★对于长零件,特别是增强型配混料,如电动机可能,应该沿纵向而不是沿横向或在中心设置浇口。
★如果在两个或以上的型腔,零件和浇口应与沿注道对称布置。
★轴向对称零件,例如齿轮、盘、叶片等,最好使用隔板浇口并且应在中心设置浇口,或者在三板模具上设多个浇口,以获得良好的实际流动特性。
★有一体式铰接的零件在布置浇口时,应使熔合线远离铰接点。
在任何情况下。
都应避免将熔料停止流动部分设计在铰接点附近。
★杯形零件(例如小壳体、电容器杯等)的浇口应设计在底座附近,以避免产生空气气穴。

JP352 or JP352F shall be installed in all cooling line openings. All water lines should enter and exit the bottom of the tool with no water connection on the top of the tool ,If it is required to have multiple waterlines a manifold for the "A" and "B" mold halvesshall be provided. The manifolds shall be either mounted to the standardized clamp plates or incorporated into the tool.The manifold shall have a single inlet and outlet per CITCO Products Inc.

Vent width to be 1/8” - 1/2” wide depending on part size and material to be molded. The distance from the end of t he relief to the cavity will be the effective vent depth.5.2All vents to be draw stoned to ensure self cleaning.Provide ejector pins or inserts in deep pockets and rib areas for venting purposes as necessary.5.3Runner system to be vented.6.0 Ejector Systems6.1If the part design required multiple thin-walled sections, two-stage ejection shall be used. As an example, the cores may be ejected first, clearing the parts from the cavities, and the part subsequently ejected from the cores.6.2Guided ejector systems shall be used wherever possible.•Ejector plates shall have a minimum of four guide posts and four return pins.•Guide posts must be secured to the clamp plate and not telescoped into or attached to the cavity plate.6.3A micro switch shall be mounted between the ejector housing and ejector plate to verify the ejector pins are in the full returnedposition before allowing the molding press to close. Switch to be used is "MICRO SWITCH" 1CH32-R6.4Ejector plate shall use die spring return and spring ratings shall be specified on drawings.6.5Ejector plate stop pins (DME or National) shall be provided.6.6Unless otherwise specified, standard SPI knockout pattern shall be provided.6.7Ejector guide post bushings shall be Lamina bronze or equivalent. (DME standard leader pins and guided ejector bushing series.) 6.8All ejector plates shall be provided with hardened riser pads. They shall be mounted to the ejectorplate for the purpose of maintaining a standardized clearance of .050" from the ejector pad to the back of the "B" clamping plate.This is to allow COMMSCOPE to standardize the molding press K.O. rods.6.9All tools using a submarine gate shall also be designed with a ejector pin adjacent to / or as close to the gate as possible to eject any partial shot without damaging the tool.7.0 Hot Runners7.1All runnerless tools shall be designed to provide the ability to purge through the hot runner system by separating the cavity retainer plate from the hot manifold while in the molding press.7.2All tools equipped with a hot sprue bushing shall use a 115 volt controller.7.3Thermoplastic hot runner will have an insulator sheet mounted to the stationary side clamp ½ “ thic k and parallel with in .002.

Parts shall be taken from consecutive shots during the run and tagged or numbered in the order in which they were produced.8.2The tool manufacturer shall furnish inspection data certifying that sample parts meet the part drawing requirements. Final acceptance of the mold will be based upon the conformance of molded parts from each cavity to the part requirements.8.3Any parts produced in advance of sample approval by COMMSCOPE Engineering shall be the responsibility of the tool manufacturer.8.4The tool shall be observed in operation by COMMSCOPE Engineering and/or Purchasing personnel at the tool manufacturer's plant.8.5COMMSCOPE is to supply plastic (no charge) unless otherwise specified in the purchase order.8.6Try outs that are performed @ the tool vendors will be required to supply the molding engineer with complete sample shots including runner (quantity to be determined by molding engineer). Also there shall be a sample that is a fill only shot that is approximately 95% to 99% full at the last place to fill. This will serve as an indication of runner balance and mold pressure transducer location.9.0 Other Information9.1The tool shall not be shipped without written approval by COMMSCOPE (Omaha) Purchasing Department.9.2The attachment pertaining to patents and technical information shall apply.9.3The mold maker is responsible for:•Insuring that mold conforms to specifications supplied by CommScope•Utilizing sound tool practices in the construction of the mold.•seek prior approval for non - desirable practices.
