The connector shell plastic injection mold design
Abstract
This article is about the connector shell plastic injection mold design, through the technological characteristics of plastics article of correct analysis and the performance of ABS material, the final design out a pair of injection mold. Plastic products have rich raw material sources, low price, good performance, etc. It in computers, cell phones, cars, motors, electrical appliances, instruments and meters, household appliances and communications products manufacturing has irreplaceable function, is widely applied. Injection molding is the main method of forming thermoplastic parts, so the application range is very wide.
Injection molding is melt the plastic raw material into the cylinder through the heating, made of high viscosity fluid, pressurized with piston or screw as a tool, makes the melt through the nozzle at high pressure into mold cavity, after cooling and solidification stage, and then out of the mould, plastic products.
Mould gating system are introduced in detail in this paper, the structure of the molding part, ejector system, cooling system, selection of injection molding machine and related parameters of checking, etc. Design. Using PRO/E CAD, auxiliary engineering such as different software respectively to the mold design, manufacturing and product quality are analyzed. Connector shell plastic injection mold design, using the general accuracy and the use of CAD, PRO/E to design or analysis of forming parts of injection mould, pouring system, guide parts and demoulding mechanism, and so on. According to the specific structure of the connector, the mould adopts the point gate double parting surface injection mould. Because there are holes plastic parts inside, need to set up the inclined guide pillar. Through the mold design shows that the mould can achieve connector quality and processing technology. Integrated use of the professional basis, professional class knowledge is designed, its core knowledge is the plastic molding mold, material molding technology base, mechanical design, plastic molding process, mould CAD/CAM, etc
.
Key words: the connector shell; Injection mould; CAD; PRO/E
