Problems solved by technology
[0004] Using the above-mentioned mold, after injection molding, it needs to open the mold four times to complete the demoulding of the battery case, which has the disadvantages of relatively complicated mold structure and low production efficiency
At the same time, because it is injected from the top of the battery case, there will be marks at the disconnection between the material head and the bottom of the battery case after demoulding, which affects the appearance and overall strength of the battery case.

Embodiment Construction
[0046] In order to further explain the technical solution of the present invention, it will be described in detail below in conjunction with the accompanying drawings.
[0047] refer to Figure 1 to Figure 8 , an injection mold for a battery case, comprising a first base plate 10, a cavity plate 30 connected to the first base plate 10, a second base plate 20, a mounting plate connected to the second base plate 20, and a The mold core 60, the needle valve type hot runner injection nozzle 70 embedded in the mold core 60, and the stopper used to limit the mold opening distance between the cavity plate 30 and the mounting plate, the cavity plate 30 is provided with a When the mold is closed, the accommodation chamber 31 , the mold core 60 and the mounting plate together form a molding chamber that matches the battery case 50 . The feed port of the needle valve type hot runner injection nozzle 70 is connected with the injection molding machine, and the discharge port of the needle...

The invention relates to an injection mold for a storage battery shell. The injection mold comprises a first substrate, a mold cavity plate connected to the first substrate, a second substrate, an installation plate connected to the second substrate, a mold core arranged in the installation plate, a needle valve type hot runner material injection nozzle embedded in the mold core and a limiting piece used for limiting the mold opening distance between the mold cavity plate and the installation plate; a containing cavity is arranged on the mold cavity plate; and a molding cavity matched with the storage battery shell is jointly defined by the containing cavity, the mold core and the installation plate. According to the scheme, the feeding direction of traditional storage battery shell injection molding is changed, feeding is carried out from an opening portion of the storage battery shell, material breaking points are prevented from occurring at the bottom of the storage battery shell, and the aesthetics and the whole stability of the storage battery shell are guaranteed; the needle valve type hot runner material injection nozzle is used in the injection mold for the storage battery shell, the functions of stably conveying materials and automatically cutting the materials are achieved, the mold opening steps are greatly simplified, and the labor productivity is improved; and in addition, the mold is simple in structure and convenient to manufacture.
Description
technical field [0001] The invention relates to an injection mold for a storage battery case. Background technique [0002] With the development of social economy and the improvement of people's living standards, plastic battery shells are widely used in all walks of life due to their light weight, fast molding, low cost, good acid resistance and corrosion resistance, and many other advantages. The outer carrier is also made of plastic battery case. The battery case is one of the important components of the outer carrier. The quality of the battery case will directly or indirectly affect the quality of the battery. [0003] An existing injection mold is disclosed in the application publication number CN 102285069 A, and the Chinese invention patent application titled "A Kind of Injection Mold". An injection mold includes a panel, a nozzle push plate, a nozzle plate, an A plate, a push plate, and an injection mold. Plate, fixed plate, bottom plate, first pull plate, guide po...
