Problems solved by technology

[0006] Therefore, it is a waste of cost to use this kind of manufacturing method, but this is the only way to ensure the life of the formal mold, but in addition to the increase in manufacturing costs, it also increases the manufacturing cycle of the mold, which is difficult for some urgent projects.

Abstract

The invention provides a plastic grating pre-deformation mold design method, and belongs to the field of molds. The method comprises the steps that 1, median correction is conducted, and 3D data is consistent with median data; 2, pre-deformation data is designed, injection molding simulation is conducted on a product, the buckling deformation result of the product is analyzed, then the pre-deformation area of the product is analyzed and determined, after the buckling deformation result conforms to CAE analysis, locking of anti-deformation data is conducted, and 3D pre-deformation data is completed; 3, mold design and manufacturing are conducted on the basis of the second step; 4, mold testing and mold repairing are conducted, the product is placed for 24H and then measured, and data adjustment of a mold 3D model is conducted on the super-difference part; and 5, mold shaping is conducted. According to the method, the mold manufacturing cost is reduced, and the requirements of the product size and the mold service life can be met through one set of mold.

Description

technical field [0001] The invention belongs to the field of moulds, and relates to the injection molding of automobile plastic products, in particular to a design method of a plastic grid pre-deformation mould. Background technique [0002] Nowadays, there are more and more plastic products on cars. Experts predict that by 2020, the average plastic consumption of cars may reach more than 500kg / car, accounting for more than 1 / 3 of the materials used in the whole car. With the promotion of lightweight design of cars, Many precision parts on the car body also use a large number of plastic products, including car sunroof brackets, AGS front air intake grilles, front-end modules, CD box brackets, handle brackets, door lifters, rearview mirror brackets, etc. [0003] Most of these precision products will perform various actions or fix some precision parts on the car body, so the dimensional tolerance requirements are very high, and the strength of the products also has high requi...
