The host box molding process and injection mold design of security system
Abstract: Security system of the host box belongs to fittings, using ABS injection molding, the appearance of the surface quality requirements, the shape is not allowed to have obvious signs. Subject to solve the die structure design is reasonable, the exhaust is better, after forming should meet precision requirement, also need to consider the deformation in the process of forming, need to collect molding process parameters and relevant materials, application of knowledge to solve practical problems in production of plastic material forming the problems.
It should completes the plastic molding process and mould design and manufacturing process design: through the study and practice of graduation design, can use UG three-dimensional three-dimensional modeling simple, understanding the performance of mechanical processing of working parts of die, know the machining process and mold process, learn to analyze and determine the gating system and the parting surface the mold flow analysis, to determine the optimum gating system. This design need to complete a set of 2D, 3D mold parts diagram, assembly drawing, complete specifications, the graduation reply.
Key words: Mechanical design; Injection mould; Security electric shell; Sloping roof
