Abstract

The invention discloses an injection molding method of a battery shell grid baffle. The method comprises following steps of molding cooling temperature control, wherein the cooling temperature of a male mold is set to 80 DEG C, and the temperature of a female mold is set to 95 DEG C; and injection molding process control, wherein a product injection molding process comprises a four-segment injection molding filling state and a two-segment pressure maintaining stage. According to the injection molding method of the battery shell grid baffle, injection molding of the battery shell grid baffle can be efficiently completed, and the injection molding quality of the battery shell grid baffle can be ensured.

Description

technical field [0001] The invention relates to an injection molding method for a grid baffle of a battery case. Background technique [0002] Such as figure 1 As shown, during the injection molding process of the grid baffle of the battery case, due to its structural characteristics, it is easy to bulge when the product grid is released (the center of the grid is easy to bulge), and at the same time, the fixed position of the top surface is prone to shrinkage defects (A surface that is prone to shrinkage), and the product is prone to deformation. Contents of the invention [0003] The object of the present invention is to provide an injection molding method for the grid baffle of the battery case, which can efficiently complete the injection molding of the grid baffle of the battery case, and can ensure the injection molding quality of the grid baffle of the battery case. [0004] In order to achieve the above purpose, the technical solution of the present invention is ...
