摘要塑料成型是将各种塑料原料制造成所需要的形状的过程。本设计通过对某种联结套筒注塑模具的设计,根据塑件ABS材料的特性和塑件产品的使用要求,对产品进行工艺分析,然后对成型方案进行分析设计,为模具的设计奠定基础。61602
该设计中的注塑模具包括模架、注塑机、注塑系统、成型零部件、脱模机构和冷却机构。其中成型零部件的结构,尺寸计算以及脱模机构中的侧向抽芯机构是本设计的核心内容。而产品材料的平均收缩率是成型零部件的尺寸计算的主要依据。
除了设计计算部分,对模具各参数的校核和模具的装配也是必不可少的内容。最后通过有限元分析软件对模具工作时的受力变形状况进行分析,确保设计的正确性。

Title joint sleeve injection mold design
Abstract The plastic molding is all kinds of plastic raw materials will be made into need to the shape of the process. This design through in joint sleeve injection molds design, according to the characteristics of plastic parts ABS material and product use requirement of product process analysis. First,analysis of forming scheme design,and then mold design to lay the foundation.
Injection mould including formwork, injection molding systems, molding parts,, the injection molding machine, demoulding mechanism and cooling units. The core content of this design is the structure of the components of molding ,size calculation and the design of molding parts size calculation . And the main basis of the average product material shrinkage is molding parts size calculation .
In addition to design the computation part, the parameters of mould of checking and mold assembly is necessary in the content. Finally through the finite element analysis software to mold work force situation to carry on the analysis, ensure the rationality and validity of the design.
