Auto switch base molding technology and injection mould design
Abstract: This manual is the auto switch seat design specification, designed by modern advanced mold manufacturing method, combined with the completion of the UG, CAD and mapping software. First of all, the seat of the car switch process analysis of the selected material is ABS plastic parts, need to consider the basic characteristics of the material, plastic parts precision size, and so on. Second, the development of rational design of the program is determined to be the point gate injection of a mold cavity, and then analyzes to determine the parting surface and the launch of the institutions, and the clamping force, injection volume, core, cavity size and other mold Part of the design and calculation. According to the more complex structure of the inner surface of the plastic parts, design the reasonable side pumping institutions.
Access to information and advisory opinions of teachers and fellow classmates in the design process, for a more in-depth understanding of mold design, to consolidate and deepen the knowledge, broaden their own design vision.
Keywords: The switch of the automobile seat; ABS; mold design
