Technical Field
[0001] The utility model relates to the technical field of vehicle shell injection molding, in particular to an injection molding mold for a small electric vehicle shell. Background Art
[0002] An injection mold is a tool used to produce plastic products through injection molding. It is also a tool that gives plastic products a complete structure and precise dimensions. During injection molding, the heated and molten plastic is injected into the mold cavity by an injection molding machine at high pressure, and the molded product is obtained after cooling and solidification. This method is suitable for mass production of parts with complex shapes.
[0003] In the current prior art, when the existing injection mold is extruding and injecting the outer shell, the inside of the mold needs to use high temperature to extrude and inject the raw materials. In order to improve production efficiency, when the accessories are injected, the employees are required to collect the accessories in time, so that after the mold is injected, the internal injection molded accessories themselves have a very high temperature. When people take the accessories manually, they are easily burned by the high temperature of the accessories themselves. Moreover, when the high-temperature accessories are stacked and stored together, the gaps between the accessories are relatively small, and the heat in the center cannot be discharged naturally. If the accessories are slightly bent when cooling down, the accessories will be bent and defective when they are finally finalized. When the bent shell accessories are assembled, some positions of the accessories will be bent, resulting in the inability to effectively dock and combine the shell accessories, which will cause the outer shell of the tram to warp and bulge due to bending during assembly.
[0004] To this end, the utility model provides an injection mold for a shell of a small electric vehicle. Utility Model Content
[0005] To this end, the technical problem to be solved by the utility model is to overcome the problem in the prior art that the temperature of the accessories themselves is relatively high and the natural cooling is relatively slow. During the shaping process, it is easy for the accessories to bend due to their own gravity and external factors, so that the final shaped accessories will have defects.
