PAGE 毕 业 设 计 题 目 电极丝骨架注射模具设计 英文题目Design of injection mold for electrode wire skeleton 摘 要 塑料制品具有原料来源丰富，价格低廉,，性能优良等特点。它在电脑、手机、汽车、电机、电器、仪器仪表、家电和通讯产品制造中具有不可替代的作用，应用极其广泛。注射成形是成形热塑件的主要方法，因此应用范围很广。 注射成形是把塑料原料放入料筒中经过加热熔化，使之成为高黏度的流体，用柱塞或螺杆作为加压工具，使熔体通过喷嘴以较高压力注入模具的型腔中，经过冷却、凝固阶段，而后从模具中脱出，成为塑料制品。 本产品是电极丝骨架，且实用性强。为保证塑件表面质量采用侧浇口，因此选用单分型面注射模。模具的型腔选择一模一腔结构，浇注系统采用侧浇口成形，推出形式为推件板推出机构完成塑件的推出。塑件的工艺性能要求注塑模中有冷却系统，因此在模具设计中也进行了设计。本次的设计查阅了大量的专业资料和书籍，丰富了设计过程。 关键词： 注射成型，侧浇口，型芯 ABSTRACT Here to enter the need to turn over a source of plastic materials, low price, quality and performance characteristics. it is in computers and mobile phones, cars and electrical and electronics, instruments, appliance and products manufacturing is an alternative to the role of the most widely used. an injection is a thermoplastic - concrete shape of the main method, the scope of application is very large. Been shaping the plastic materials in rolls of the material being heated, which has become a highly fluid bolts, or as the pressure of tools, the melted by regulated by a high pressure injection mould of form, after a cooling and solidify, and then die from the adjustment, as of plastic. The product is the skeleton of Electrode wire, and with high practicability. the product design for mass production, the design molds to have high molding efficiency, the system can automatically release, in addition to ensure the quality of the surface forms a side gate and therefore use single cent for the injection, the side gate automatically release the structure of the type. the machine mold is a choice of a module four chambers structure, the system uses the side gate to push out of shape, form a board with the agency to complete the forms of the launch of the process. Key words:injection; side gate; a core 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc327861685 绪论 PAGEREF _Toc327861685 \h 1 HYPERLINK \l _Toc327861686 1. 塑料的分析 PAGEREF _Toc327861686 \h 5 HYPERLINK \l _Toc327
