遥控器电池后盖注塑模具设计
摘要
本文详细介绍了遥控器电池后盖注塑模具的设计,共分十四节,主要包括:塑件材料的分析与设计方案的论证;注塑机的选择;模具结构的设计;成型零件的设计;导向机构的设计;脱模机构的设计;侧向分型与抽芯机构的设计等。
本次设计为一模两腔,塑件材料选用了丙烯腈-丁二烯-苯乙烯共聚物(即工程材料ABS),浇口形式选用了侧浇口,模具结构为直接分型——推杆推出机构。通过以下计算和设计是可行的,并可以应用到实际生产中。
本次设计主要是对一种塑料遥控器电池后盖进行模具设计。本文先介绍了注射模具国内外的发现状况及发展趋势,其次介绍了注射成型原理和工艺过程;根据塑件要求选择合适的注塑机,进而选择合适的浇注系统与冷却系统;通过计算,对导向机构、脱模机构和侧向分形与抽芯机构进行设计。
该模具的凸凹模均采用嵌入式的型腔和型芯,精度高,节省材料,改善了模具加工的工艺性,降低了模具的生产成本。该模具采用单分型面设计,通过滑块和斜导柱实现开合模动作,模具运动平稳可靠。塑件能顺利脱模,该模具总体结构设计合理,模具的制造成本低。成型的壳体塑件质量合格稳定,使塑件质量符合设计和使用要求。

The Design of the Telecontroller Injection Mold
Abstract
This paper introduced the design of telecontroller,and consisted 14 include analysis of plastic material and argumentation of design project; selecting injection machine; devising mold structure;devising molding parts; devising oriented framework; devising stripping framework; devising side parting and pulling framework.
The mold is consisted of two cavities. The plastic material select acrylonitrile butadiene-styrene copolymer ( material ABS). The sprue form choose a side gate, die structure for direct classification--push rod pushing the following calculation and design is feasible, and can be applied to practical production.
The design is mainly remote control battery cover of a plastic mold design. This paper first describes the situation and development trend of the injection mold found at home and abroad, followed by injection molding principle and process; plastic parts require the injection molding machine, and then select the appropriate gating system and cooling system;, oriented agencies, stripping agencies and lateral fractal design core-pulling mechanism.
The mold punch and die are embedded in the cavity and core, high precision, material savings, improved mold process, reducing the cost of production of the mold.
