With the development of industrial plastic,plastic injection mold plastic products have become the main method of forming one.Die in the manufacturing sector and the status of increasingly high level of technical level of the mold,has become the manufacturing sector of a country's level of the important signs.This article detailed introduction of the mold design of the whole process,the design of the highlights is based on the shape of plastic parts,technical requirements and the actual situation of production by analogy to determine the best form of mold and structural.The design of the mirrors covered technology,the design of the rear-view mirror covered injection mold structure,and through the cavity pressure and the clamping force,the choice of injection molding machine,given the relevant technical parameters.This design is the difficulty of plastic parts on the existence of the uplift of the need to uplift the plastic parts on the part of the molding and die separated from manufacturing,using a ramp mandril structure.This structure can be used to reduce mold manufacturing costs,while the mold to achieve the best optimization.To reduce die costs,increase productivity,for a national standard parts,the design of a standard parts,including: injection mold-standard mode; standards-guided,guided sets,and so on.The recommended size of the parts are optional recommended design,such as gate sets,and so on.
