Design of injection mold base cleaner
Abstract: plastic mold used in today's society is more and more widely, from the computer, mobile phone, beverage, desk lamp, pen, the basin, the application is extremely broad, it can be said that from our food and clothing live line cannot do without it. Injection molding is the main method of forming thermoplastic parts, so a wide range of applications. The plastic injection molding is the raw material into the barrel through the heating and melting, making the high viscosity of the fluid, used as a plunger or screw compression tools, cavity melt through the nozzle into the higher pressure in the mold, after cooling, solidification stage, and then ejected from the mold, a plastic products. This graduation design is the design of injection mold for vacuum tube, based on process performance and number of plastic products are designed with 1 times parting surface of injection mold are determined. The mold cavity using a mold 2 cavity is arranged in a straight line, pouring system adopts the side gate forming, roll out in the form of mechanism to complete the introduction of plastic parts. Because the plastic parts of the process performance requirements of injection mold cooling system, so also in the mold design to design. The design of the reference to a lot of literature, is still on the Internet to find information, the design process is complete.
Keywords:1 injection mold parting surface; the side gate; inside the pumping
