Embodiment Construction

[0016] In order to enable those skilled in the art to fully understand the technical solutions and beneficial effects of the present invention, further description will be given below in conjunction with specific examples.

[0017] figure 1 It is a common structure of injection molds for battery casings at present. A cavity is provided on a whole template, and a rectangular battery casing is injection-molded by cooperating with the core of another template. After considering demoulding and cost factors, generally no special structure will be designed on the side wall of the cavity (at this time, the side wall of the cavity is flat and perpendicular to the plane of the template). The side wall of the storage battery casing formed by the mold will shrink and deform inwardly after cooling, and is inconvenient to carry.

[0018] In order to solve the above problems, the applicant has designed a set of new battery shell molds, such as Figure 2-5 shown. The mold includes a match...

Abstract

The invention relates to a four-sided slide block and a pre-deformed accumulator shell mold, which solves the defects of the existing molds such as product concave due to shrinkage and cooling deformation, side walls without reinforcement or handling structure, and the like. The mold can easily and quickly open the mold and pull the core while forming the ribs and slots on the battery case through the 4 oblique sliders arranged around the cavity, and the pre-designed protrusions compensate for the shrinkage after cooling. Product Size. The structure of the mold is relatively simple. After mass production verification, the concave phenomenon on both sides of the plastic shell is completely eliminated. There is no need for stereotyped tooling, the product size remains stable, the production efficiency is greatly improved, and customer satisfaction is high.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a four-sided slider and a pre-deformed battery shell mold. Background technique [0002] The battery casing is a protective shell wrapped around the car battery. It is large in size and has a partition in the middle to facilitate the placement of battery cells. The battery shell is usually made of plastic, and it is mostly injection molded with a relatively simple mold. However, due to its large length, width and height, it is easy to shrink and deform when it is cooled after molding, causing each surface to be concave, which deviates from the original design size and affects the qualification of the product. Rate. On the other hand, the battery casings currently on the market have a relatively simple structure, with all four sides flat, and no slots for mounting handles, resulting in insufficient strength and inconvenient handling. Contents of the invention [0003] The p...
