弯管接头注射模具设计
摘要
塑料是以高聚物为主要成分的物质，它的特点是重量轻，比较坚固，耐化学腐蚀性和电绝缘性优良，市场上塑料价格相对便宜，具有不错的可塑性，在电脑、手机、汽车、医疗器械、电器、家电和通讯产品制造中有着广泛的应用。通常塑件是用塑料熔体注射进注射模具的行腔中形成的。注射模具有很多优点，比如成型效率高、生产出的塑件一致性好，可以自动化操作，可以大量生产复杂零件，加工成本不高。本次设计的产品为弯管接头，它的特点是重量轻，强度高，耐腐蚀，易清洁，适合大批量生产。要完成本次设计，首先要先分析塑件的工业特点，然后确定其注射成型原理，选择合适的注射机和模架。然后要确定模具的分型面、型腔数目、流道结构、浇口形式和位置。接着要确定塑件在模具中的位置，从而才能选择模具内部零件结构，和塑件的固定形式。然后根据这些设计模具的脱模、推出等机构。最后要完成一份模具设计的装配图、三维图和一份设计报告。

Design of Injection Mold for Pipe Joint
Abstract
Plastic is a high polymer as the main component of the material, which is characterized by light weight, relatively strong, resistant to chemical corrosion and excellent electrical insulation, the market price of plastic is relatively cheap, with good plasticity, in the computer, mobile phone, car , Medical equipment, electrical appliances, household appliances and communications products manufacturing has a wide range of applications. Usually the plastic parts are filled with plastic melt into the injection cavity of the injection mold. Injection mold has many advantages, such as high molding efficiency, the production of plastic parts consistency, and can be automated operation, you can mass production of complex parts, processing costs are not high. The graduation design of the product for the elbow joints, which is characterized by light weight, high strength, corrosion resistance, easy to clean, suitable for mass production. To complete this design, we must first analyze the industrial characteristics of plastic parts, and then determine the principle of its injection molding, select the appropriate injection molding machine and mold. And then to determine the mold parting, cavity number, flow channel structure, gate form and location. And then to determine the plastic parts in the mold position, so as to determine the structure of the cavity, as well as the plastic parts of the fastening. In addition to design stripping mechanism, mold-oriented mechanism and cooling system. Finally, drawing a complete drawing of the mold and the relevant parts of the drawings and parts of the map, the preparation of parts and components of the manufacturing process process cards, complete the design of the general instructions. Practice has proved that: the mold structure is reasonable and reliable, and to ensure product quality, such injection molding products, mold design reference value.
