塑料筷笼注塑模具设计与制造.doc

摘要 本设计包括模具结构设计的塑料筷笼、相关流程和结构参数分析。我们的主要对象是实现简单,结构紧凑,良好的工艺性能、高精度、长寿命、短周期、高效、低成本。基于需求的塑料制品、模具结构设计设计的依据有:1、大批量生产；2、筷笼零件（实物）；3、国家有关注射模具设计标准(GB8846-88)。 依据筷笼产品要求和塑料件的工艺特点：塑料件表面光洁、外形美观协调、零件壁薄融熔塑料流动距离长且进人型腔后流动阻力大浇口形式。CAD introduction This design includes the mould structure design of dual-use (table/wall) box of chopsticks, related process and structure parameters analysis. Our main objects are to achieve simple and tight structure, good processing property, high-precision, long-life, short-cycle, highly efficient, and low cost. The design is based on: 1.mass production; 2.box of chopsticks (entities); 3.nation standards of injection mould design (GB8846—88). Based on the requirements of the plastic products, mould structure design and injection processing: bright, clean, aesthetic shape, small wall thickness, long runner for the plastics, lager flowing resistance, we select PP as plastic material, use more pin-point gate, two side core. The design consists of two parts: one is the mould design using CAD/CAM, use 3D design software, i.e, Pro/Engineer, mapping entities model and generating two-dimensional drawings, and then obtain drawings of the parts and assembly using AutoCAD; The second is an analysis of the calculation for the mould structure and injection processing, including structural design, the choice of the injection mould machine and the mould carrier, the design of pouring system, mould parts, side plugger mechanism，mould emptier and cooling system .
