DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] It should be noted that when a component is referred to as being "mounted on" another component, it may be directly on the other component or there may be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a central component at the same time. When a component is considered to be "fixed to" another component, it may be directly fixed on the other component or there may be a central component at the same time.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0021] like Figures 1 to 4 As shown, this embodiment discloses a battery shell injection mold, including an upper mold base 1 and a lower mold base 2, wherein the upper mold base 1 is connected to the lower mold base 2 in an upper and lower distribution, the bottom end of the upper mold base 1 is provided with an upper mold plate 3 fixedly connected thereto, the top end of the lower mold base 2 is provided with a lower mold plate 4, the lower mold plate 4 is provided with a mold core 5 embedded therein, the mold core 5 is a rectangular parallelepiped structure, the mold core 5 is provided with two groups of mold holes 9 distributed in parallel, and the lower mold plate 4 is provided with a limiting mechanism, which is used to prevent the movement of the mold core 5. When the heated and melted plastic is injected into the mold cavity by the injection molding machine under high pressure, the heated and melted plastic flows through the material channel to the mold core, and after cooling and solidification, a formed product is obtained. By setting a limiting mechanism, the mold core can be prevented from moving when it is impacted by the hot melt plastic.

[0022] In this embodiment, the limiting mechanism includes a limiting base 11, a limiting baffle 12 and a limiting column 13. The limiting base 11 is fixed on the lower template 4, the limiting column 13 is fixed on the limiting base 11, the limiting baffle 12 is installed on the side of the limiting base 11 close to the mold core 5, and the mold core 5 is provided with a limiting groove 14 that is compatible with the limiting baffle 12. The limiting baffle 12 is placed in the limiting groove 14 to prevent the mold core 5 from moving.

[0023] In this embodiment, the mold core 5 is provided with two groups, namely the first mold core and the second mold core. Each mold core 5 is provided with a group of mold holes 9, and the number of mold holes 9 in each group is four. A gap is provided between the two groups of mold cores.

[0024] like Figure 4As shown, in this embodiment, a cavity 6 is provided on one side of the upper template 3 close to the lower template 4, and a plurality of threaded columns 10 are provided in the cavity 6, and each of the threaded columns 10 corresponds to a mold hole 9. The existing battery shells need to be stacked together for shipment, and at this time, it is necessary to open additional holes and groove structures on the battery shells, and the process is relatively complicated. The present mold directly processes a threaded column structure in the cavity of the upper template, and the threaded column 10 is threadedly connected to the mold hole 9 on the mold core 5. When the heat-melted plastic is injected into the mold, a threaded hole structure is processed on the battery shell. The threaded structure can fix the battery shell and the battery placed therein together, and it can also facilitate the stacking and transportation of the injection-molded battery shells. The present injection mold can directly obtain a finished battery shell with threads, without the need for additional processing, shortening the process flow and reducing the defective rate of the product.

[0025] In this embodiment, the limiting column 13 passes through the upper mold plate 3 and the upper mold base 1 in sequence.

[0026] In this embodiment, a material channel 7 is provided through the upper mold base 1 and the upper mold plate 3 , and the material channel 7 is communicated with the mold core 5 .

[0027] In this embodiment, the lower mold base 2 is provided with ejector rods 8, and each group of ejector rods 8 sequentially penetrates the lower mold plate 4 and the mold core 5 for ejecting the molded product.

[0028] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
