肥皂盒上盖注塑模具设计

摘要：本次设计的是肥皂盒注塑模具设计，主要是上盖的设计。首先介绍了塑件的工艺分析，其中包括塑件设计要求，塑料特征，收缩率及密度等，并根据塑件的大小确定注射量的大小，最终采用一模两腔，进而确定注射机为XS-ZY-125型卧式注射机，接着通过对肥皂盒进行工艺的分析和比较，最终设计出一副肥皂盒注塑模。从塑件的材料和成型工艺以及具体模具结构出发，对模具的浇注系统、排气系统、冷却系统以及模具成型部分的结构（顶出机构、推出机构等）进行详细的设计，同时并简单的编制了塑件加工工艺。通过整个设计过程表明该模具能够达到塑件所要求的加工工艺，并生产出合格的产品。本次设计的主要任务是对选定的肥皂盒进行简单分析之后进行造型设计，同时设计出较好的注塑模具，以实现肥皂盒的自动化生产，提高产量。根据肥皂盒的具体结构和计算数据表明该模具应该采用点浇口的单分型面注射模具。最后通过模具设计与校正表明该模具能达到肥皂盒的表面质量要求和加工工艺要求。

The soap box injection mold design

Abstract：This design is the soap box injection mold design. Firstly introduces the analysis of the technology of plastic parts design requirements including plastic parts, plastic characteristics, shrinkage and density etc., and according to the size of the plastic parts to determine the injection amount, use one module and two cavities, and then determine the injection machine for the XS - ZY - 125 type horizontal injection machine. Then through the analysis and comparison of the soap box process, the final design out a pair of soap box injection mold. From the product of the material and forming process and die structure, the specific of mould gating system, exhaust system, cooling system and mold forming part of the structure and the ejection mechanism, launch mechanism and so on carries on the detailed design, at the same time and simple formulation of the plastic parts

processing technology. Through the whole design process shows that the mould can achieve plastic parts required processing technology, and produce the qualified product. This design is the main task of the soap box to carry on the simple analysis of the selected modelling design, good injection mold design at the same time, so as to realize the automation production, soap box to increase production. The soap box according to the specific structure of the mould is point gate single parting surface injection mould, use two plate cold runner. Finally through the mold design shows that the mould can achieve the soap box surface quality and processing requirements.
