塑料骨架注射模

摘要

近年来，我国家电工业的高速发展对模具工业，尤其是塑料模具提出了越来越高的要求，2004年，塑料模具在整个模具行业中所占比例已上升到30%左右，据有关专家预测，在未来几年中，中国塑料模具工业还将持续保持年均增长速度达到10%以上的较高速度的发展。国内塑料模具市场以注塑模具需求量最大，其中发展重点为工程塑料模具。

注射成型是塑料成型的一种重要方法，它主要适用于热塑性塑料的成型，可以一次成型形状复杂的精密塑件。本课题就是将塑料骨架作为设计模型，将注射模具的相关知识作为依据，阐述塑料注射模具的设计过程。

本设计对塑料骨架进行的注塑模设计，对塑件结构进行了工艺分析。明确了设计思路，确定了注射成型工艺过程并对各个具体部分进行了详细的计算和校核。如此设计出的结构可确保模具工作运用可靠，保证了与其他部件的配合。最后用AutoCAD绘制了一套模具装配图和零件图。

本课题通过对塑料骨架的注射模具设计，巩固和深化了所学知识，取得了比较满意的效果，达到了预期的设计意图。

Mould plastic framework

ABSTRACT

In recent years, China's household electrical appliance industry in the development of high-speed tooling industry, especially the plastic mold to the growing demands, in 2004, plastic mold in the mold industry in the proportion had increased to about 30 percent, according to relevant experts predict, In the next few years, China plastic mold industry will continue to maintain an average annual growth rate reached over 10 percent of high speed development. The domestic market to mold plastic injection mold the demand is greatest, of which focus on the development of engineering plastics mold.

Plastic injection molding is an important method of molding, which apply mainly to the thermoplastic plastic molding, can be a complex shape of the precision molding plastic parts. This issue is the plastic cover as a design model, the injection mold-related knowledge as the basis on the design of plastic injection molding process.

The design of plastic injection mold covered the design, structure of the plastic parts of the process. Defined the design, determine the injection molding process and the specific part of a detailed calculation and verification. So the structure can be designed to ensure that the use of reliable mold work to ensure that the co-ordination with other components. Finally, AutoCAD drawing a mold assembly and parts plans.

Framework by plastic injection mold design, consolidated and deepened by knowledge, has been relatively satisfied with the results, achieved the expected design intent

KEY WORDS: the plastic mold, plastic injection molding, mold design
