摘要
塑料制品已在工业,农业,国防和日常生活中的方面得到广泛应用。特别是在电子业中则为突出。电子产品的外客大部分是塑料制品,产品性能的提高要求高素质的塑料模具和塑料性能。成型工艺和制品的设计。
塑料制品的成型方法很多。其主要用于是注射,挤出,压制,压铸和气压成型等和气压成型等。而注射模,挤出约占成型总数的60%以上。注射成型分为加料,熔融塑料,注射制件冷却和制件脱模等五个步骤。当然如利用电气控制。可实现半自动化或自动化作业。
塑料注射模主要用于热塑料制品的成型,已成功的用于成型热固塑性塑料制品,它是塑料制品生产中十分重要的工艺装置。注射模的基本组成是:定模机构,动模机构,浇注系统,导向装置,顶出机构,芯机构,冷却和加热装置,排气系统。
因注射模成型的广泛适用,正是我这个设计的根本出发点。本设计是根据给定的实物——面巾纸的塑料盒,以及其尺寸来设计一副具体的模具,主要对浇注、成型、脱模部分进行了具体的设计。
关键词: 浇口型芯型腔脱模
Abstract
Plastic products in industry, agriculture, national defence and widely used in everyday life. Especially in the electronic industry was highlighted. Electronic products, foreign guests are mostly plastic products, the improvement of product performance requirements of high quality plastic mold and plastic properties. Design of the forming process and products.
Plastics molding method. It is mainly used for injection, extrusion, pressing, die casting and pressure and gas forming. The injection mold, extrusion accounted for more than 60% of the total number of molding. Injection molding is divided into charging, melting plastic injection parts, cooling and demoulding products in five steps. Of course, such as the use of electrical control. Can achieve semi-automatic or automatic operation.
Mainly used for plastic injection mold molding of plastic products, has been essfully used for molding of thermosetting plastic products, it is a very important technology device in the production of plastic products. The position of injection mold: mold mechanism, dynamic mechanism, gating system, guiding device, the ejection mechanism, core mechanism, cooling and heating device, the exhaust system.
Because the widely used injection molding, is the fundamental starting point of my design. The design is based on the given object -- plastic box of tissues, and its size to design a specific mold, casting, moldi
