本次模具设计详细地介绍了异型管接头模具设计,通过对接头模具结构的了解以及设计与其分析.对聚甲醛这种热塑性材料的主要用途和其功能的了解.模具设计主要采用一模两腔单分型面和侧浇口。同时,采用了滑块、斜导柱和顶出套脱模机构。开模时,滑块首先靠着倾斜导柱的自重作用侧进行抽芯,然后,顶出滑块随着机构的运动,将制件顶出,再靠着注塑件的自重运动掉落下来。顶出装置必须在滑块复位时将凸出套提前与型销复位,否则滑块顶出套将直接阻碍型销前进。因此,弹簧必须一定要具备具有足够迫使顶出机构复位的传动能力。根据任务的温度要求,在每一个塑件的注塑和成型的过程中,模具和塑件都需要有合适的冷却温度,所以在注塑成型模具上分别开设了四条冷却水管对每个塑件和模具的冷却温度都进行了控制。设计的流程主要包括:成型塑件的材料结构和性能的分析、注塑机的设计和选择、分型塑料表面的结构设计、浇注系统的结构设计、成型塑料零件的整体结构和尺寸的设计、塑件的脱模机构的设计、冷却系统的结构设计和主要的成型塑料零部件的设计与制造。

This mold design introduces the die design of the special-shaped pipe joint in detail. Through the understanding of the joint mold structure and its design and analysis, the main uses and functions of the polyacetal thermoplastic material are understood. The mold design mainly adopts one mold, two chambers, single parting surface and side pouring gate. At the same time, the slide block, the inclined guide pillar and the ejector sleeve demoulding mechanism are used. When opening the mold, the sliding block first pulls the core against the self weight side of the inclined guide pillar, and then, with the movement of the mechanism, the ejected sliding block ejects the part, and then falls down against the self weight movement of the injection molding part. The ejecting device must reset the protruding sleeve and the type pin in advance when the slider is reset, otherwise the ejecting sleeve of the slider will directly block the type pin from moving forward. Therefore, the spring must have enough transmission ability to force the ejector to return. According to the temperature requirements of the task, in the process of injection molding and molding of each plastic part, the mold and plastic part need to have appropriate cooling temperature, so four cooling water pipes are set on the injection molding mold to control the cooling temperature of each plastic part and mold. The design process mainly includes: analysis of material structure and performance of molded plastic parts, design and selection of injection molding machine, structural design of parting plastic surface, structural design of pouring system, design of overall structure and size of molded plastic parts, design of demoulding mechanism of plastic parts, structural design of cooling system and design and manufacturing of main molded plastic parts.<br>
