The invention relates to the technical field of injection molding, and provides a design method of an injection mold, an injection molding method and the injection mold. The design method of the injection mold comprises the following steps: acquiring predicted deformation data of a predicted product relative to a target product; according to the predicted deformation data, adjusting preset parameters to reduce the predicted deformation data to first deformation data; performing reversible deformation design according to the first deformation data to obtain a prefabricated mold; obtaining second deformation data according to deformation data of a prefabricated product obtained by the prefabricated mold relative to the target product; and performing reversible deformation design according to the second deformation data to obtain a target mold. According to the design method of the injection mold, the injection molding method and the injection mold, the operation method is simple and practical, the application range is wide, the injection molding effect is better, and universality and practicability are better.
Description
technical field [0001] The invention relates to the technical field of injection molding, in particular to a design method of an injection mold, an injection molding method and an injection mold. Background technique [0002] There are usually two ways to combine plastic parts and metal parts: one is through separate molding production and then assembled, such as manual or automatic assembly, welding assembly, glue assembly, etc.; the other is through in-mold injection molding. [0003] Among them, the method of assembly production requires high labor or equipment costs, and in-mold injection molding usually needs to solve the deformation problem caused by the inconsistent shrinkage of plastic parts and metal parts. In order to solve the problem of in-mold injection deformation, in the related art, it is used to reduce the amount of plastic parts or strengthen the strength of metal parts. These two methods generally reduce the volume of plastic parts and increase the volume ...
