接线盒注射模设计+CAD图纸

摘要：塑料模具在当今社会越来越广泛的应用，从电脑、手机、饮料、台灯、水笔、水盆等方面应用极其广泛，可以说从我们的吃穿住行都离不开它。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。
本次的毕业论文设计是接线盒的注塑模的设计，该模具结构简单，成型分型都非常简单。依据产品的数量和塑料的工艺性能确定了以单分型面注塑模的方式进行设计。模具的型腔采用一模两腔布置，浇注系统采用点浇口成形，推出形式为斜推杆推出机构完成塑件的推出。由于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。本次的设计中参考了大量的文献，还在互联网上查找资料，设计过程比较完整。19687

Junction box injection mold design
Abstract: Plastic mold in today's society more widely used, from computers, mobile phones, drinks, table lamps, pens, and other aspects of the application is extremely broad basin, we can say from our clothing, housing row without it. Injection molding is the main method of forming thermoplastic parts, so it has a wide range of applications. Injection molding the plastic material is heated to melt into the barrel, so that a high viscosity fluid, with a pressing tool as a plunger or a screw, to melt the higher pressure through the nozzle into the mold cavity, after cooling , solidification stage, and then removed from the mold, the plastics products.
   The graduation project is the design of injection mold junction box, the simple structure of the mold, molding type are very simple. And process performance based on the number of plastic products identified with a single injection mold parting surface design approach. Mold cavity using a two-cavity mold layout, gating system using point gate forming, introduced in the form of oblique putter launched agencies to complete the introduction of plastic parts. Because plastic injection molding process performance requirements have cooling systems, and therefore also in the design of the mold design. The reference design of a large number of documents, also on the Internet to find information, more complete design process
