Embodiment Construction

[0035] In order to facilitate those skilled in the art to understand the present invention, the present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

[0036] A method for forming a battery casing embedded with metal parts provided by the present invention includes: providing the metal parts, and pretreating the metal parts; After closing the mold with the fixed mold, the injection molding raw materials are injected into the mold to combine the metal parts and the plastic; after cooling and demoulding, the injection molded products combined with the metal parts and the plastic are obtained, and finally the injection molded products are inspected to screen out qualified products and defective products .

[0037] A plurality of connection grooves are evenly distributed on the side wall of the metal part, and the connection grooves can allow injection molding raw materials to flow in, thereby enhancing the ...

Abstract

The invention relates to the technical field of injection molding processing, in particular to a method for forming a battery shell inlaid with a metal part and the battery shell. The pretreated metalpart is placed at the preset position of an injection mold; after a movable mold and a fixed mold of the injection mold are closed, injection molding raw materials are injected into the molds, and the metal part and plastics are combined; after cooling and demolding, injection molding products with the metal part and the plastics combined are obtained; and finally, the injection molding productsare checked, qualified products and defective products are screened out. According to the method for forming the battery shell inlaid with the metal part and the battery shell, the metal part is pretreated before injection molding, the surface smoothness of the metal part is fully guaranteed, and therefore the metal part and the plastics can be connected better. Meanwhile, the metal part is preheated, and therefore the problem that after forming, connection between the metal part and the plastics is not stable can be avoided. In addition, data of the injection molding products are collected through an image sensor, and compared with standard data prestored in a computer, whether the injection molding products are qualified or not is judged, the defective products are fast screened out, andthe quality of the injection molding products is guaranteed.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to a method for forming a battery case embedded with metal parts and the battery case. Background technique [0002] Injection molding, also known as injection molding, is a molding method of injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automatic operation, various designs and colors, simple to complex shapes, large to small sizes, accurate product sizes, easy replacement of products, and complex shapes. Parts, injection molding is suitable for mass production and complex shape products and other molding processing fields. According to different use requirements, some injection molding products need to inlay metal parts in them. The injection molding of metal parts is generally placed in the preset position of the injection mold in advance, and then the molten injection molding raw material is injected i...
