饭盒注塑模具设计 摘 要 塑料工业是当今世界上增长最快的工业门类之一，而注塑模具是其中发展较快的种类，因此，研究注塑模具对了解塑料产品的生产过程和提高产品质量有很大意义。 本设计是关于饭盒注塑模具的设计，通过对塑件进行加工工艺方案和设计原理的分析，制订出饭盒注塑模具结构设计方案。首先分析塑件结构工艺参数，如尺寸精度和表面粗糙度。然后初步选定注射机类型，根据以上数据对模具的结构进行设计，如：型腔数目及位置的确定，分型面的选择，浇注系统的设计;对成型零部件的结构设计以及成型零部件的工作尺寸的计算。 查阅相关文献资料，选用标准模架。根据标准模架，设计结构零部件，比如：垫块的设计，推板的设计，合模导向机构的设计以及脱模机构的设计等等。注塑模具中还要有温度调节系统的设计。 通过本设计，可以对注塑模具有一个初步的认识，注意到设计中的某些细节问题，了解模具结构及工作原理。 关键词：注塑模具，成型零部件，工艺参数，分型面 Box injection mold design ABSTRACT Plastics industry in the world today one of the fastest growing industry category, while the injection mold is one of the types of rapid development, and therefore the study of plastic injection molds for understanding the production process and improving product quality is very significant. The design is built on the bucket injection mold design, plastic parts through the processing technology and design principles of the analysis program to develop water removable tops injection mold structure design. First, the structure parameters of plastic parts, such as dimensional accuracy and surface roughness.Then the initial selection of injection machine type, based on the above data, the structure of the mold design such as: The number and location of the cavity determine the choice of sub-surface, gating system design; of the shape and structural design of components forming parts the work of the size of the calculation. Access to relevant documents, use the standard mold. According to the standard mold base design of structural parts, such as: Pad design, push the board design, mold design and mold release guide mechanism mechanism design, etc… Injection mold, you should also have temperature control system. Through this design, injection mold may have a preliminary understanding, noting some of the details of the design, structure and working principle about mold.
