PAGE IV PAGE III 塑料注射成型机合模部分设计 摘 要 塑料注射成型机简称注塑机,是利用塑料成型模具将热塑性塑料或热固性塑料制成各种塑料制品的主要成型设备。注塑机合模部分的设计分为五部分,包括合模电机的选型、滚珠丝杠的详细设计、五曲肘合模机构的设计校核、调模机构以及拉杆的设计与校核。 本文以小型全电动式注塑机为设计目标,摒弃机械液压式注塑机中采用合模油缸作为执行机构,而是采用电机+滚珠丝杠的传动方式,实现注塑机的合模动作;采用调模电机实现调模动作。本文完成了合模电机、调模电机的选型设计、滚珠丝杠、拉杆、五曲肘合模机构的详细设计和部分校核。 全电动式注塑机比机械液压式注塑机响应速度快、精度高、节水节电、无油液污染。 关键词:全电动式注塑机,合模装置 Design of Clamping Component in Plastic Injection Molding Machine Abstract Plastic injection molding machine is referred to as the injection molding machine. It is the main forming equipment which can convert plastic molding thermoplastic or thermosetting plastics into plastic products. Design of injection molding machine clamping part is divided into five parts, including selection of the mold closing motor, detailed design of ball screw, design of five-toggle clamping mechanism and mould adjusting mechanism and design and checking draw rods. The goal of this paper is the small all-electric injection molding machine. It abandons the mechanical hydraulic injection molding machine and closing mould cylinder as the actuator, but using the “drive motor + ball screw”. It realizes the mold closing action of injection molding machine. This paper completed selection design and detail design of the mold closing motor and die adjusting motor, ball screw, rod, five-toggle clamping mechanism. Fully electric injection machine has faster response speed, higher precision, more energy saving and no oil pollution than the mechanical hydraulic injection molding machine. Key words: Fully electric plastic injection molding machine, clamping component 目 录 摘要 …………………………………………………………………………………………Ⅰ ABSTRACT …………………………………………………………………………………… Ⅱ 1 概述 ………………………………………………………………………………………1 1.1 国内外塑料注塑成型机市场发展现状…………………………………………1 1.2 注塑机工作原理……………………………………………………………3 2方案论证 ……………………………………………………………………………………5 2.1合模机构的类型和选择………………………………………………………5 2.2 电动式合模机构的选择…………………………………………………………… 6 3合模机构的参数及尺寸参数计算………………………………………………… 8 3.1 合模力的确定 ……………………………………………………………………
