The electric heater control panel design around the design of injection mould to launch, and introduces the basic principle of injection molding, especially the single injection mold parting surface of the structure and the working principle, the use of mold design software design and drawing and the pletion of electric heaters control panel general design of the injection mould, first 3 D modeling plastic parts, and the plastic parts for technology analysis, analysis of the shape of the plastic characteristics, size, dimensions method, precision requirements, the surface quality and the properties of materials, and other factors. Use Moldflow for mold flow analysis, choose the best gate location, analyzes the pressure drop, welding scar, airpocket, warping and so on, as well as to the molding parts and of the calculation of the size of injection machine clamping force, maximum amounts are given, injection pressure, open mold stroke and moulds and injection machine installation part of checking relevant sizes. Next to the injection molding principles and process characteristics, injection mould structure and injection machine, plastic products in the position of the mould and pouring system design, molding parts design, structure parts design, points out the type selection, mechanism design, side parting and corepulling mechanism design, temperature control system is introduced. In the whole process of graduation design familiar with the work principle of the die design。 Familiar with mould design software for use of the fastest, most superior finish design method, the design of the software I use to plete parts modelling and formwork assembly, reintroduce AutoCAD, finally AutoCAD2021 painted a set with mold assembly drawing and parts graph, design process to pare various solutions, and optimize the design, with a large picture in order to better understand the design.
