Abstract
Whether in heavy industry or in the day-to-day hardware manufacturers die have played an extremely important role in our lives, so die design has now become a hot industry. The quality of injection molding processing is one of the signs of plastic processing industry technological development level. At the same time reflects the mold level of design and manufacture . It described the design of the whole process of the brush cleaning injection mold base in detail in this manual . First of all plastic parts of the structure of the selected material and forming process, such as a detailed analysis of plastic parts of the surface structure and gate injection molding plastic parts of the overall program; and then the design of mold parts, such as forming parts, Demoulding agencies and so on. At the same time throughout the design process, but also to the need for plastic parts design and Pro / E model, and then on the three-dimensional simulation of sub-entities mold, to draw the parameters of the core, and then the structural design and calculations, and finally with Pro / E and Auto / CAD software and assembly of major components used to draw Fig. Would also like to have completed the final design verification and test program to determine the reasonableness and feasibility. In structural design, the design of this innovation lies in the choice of rack and pinion inclined core pulling and putting up mold type valve structure, so that mold compact structure, reasonable. Key words: injection molding, injection mold design, process analysis
