Description

Technical Field

[0001] This utility model belongs to the field of mold technology and relates to a core-pulling mold for the outer slider of plastic parts for electric vehicles. Background Technology

[0002] Injection molds are tools used to produce plastic products, giving them a complete structure and precise dimensions. Injection molding is a processing method used for the mass production of complex-shaped parts. Specifically, it involves injecting molten plastic into a mold cavity under high pressure using an injection molding machine, followed by cooling and solidification to obtain the molded product. In existing electric vehicle plastic parts injection molding processes, due to the complex shapes and numerous internal recesses and holes, these parts are prone to getting stuck in the mold cavity during mold opening. This requires manual removal, resulting in edge damage or product deformation, necessitating secondary reshaping. This increases labor and production costs, and reduces work efficiency and yield. Therefore, to address these issues, a new external slider core-pulling mold for electric vehicle plastic parts is proposed. Utility Model Content

[0040] Working principle:

[0041] An injection port assembly 2 is inserted into the moving mold plate 1. One side of the moving mold plate 1 is provided with a runner assembly 10 and a connecting block assembly 3, while the other side of the connecting block assembly 3 is provided with a moving mold base 4. Thus, the moving mold plate 1 and the moving mold base 4 form an integral structure. A fixed mold base 5 is pressed onto the other side of the moving mold base 4. The moving mold core 401 located inside the moving mold base 4 and the fixed mold core 501 located inside the fixed mold base 5 merge into a complete cavity. Injection molded liquid is injected into the runner assembly 10 using the injection port assembly 2, and the runner assembly 10 then injects liquid into the cavity. The fixed mold core 501 contains a core block 12 and an ejector block 15, both positioned and attached to one side of the product part. The top of the core block 12 and the push block 15 are also part of the product part. On the other side of the fixed mold base 5, there are support blocks 6 and fixed templates 7 respectively. There is a top plate assembly 8 between the fixed mold base 5 and the fixed template 7. On the top plate assembly 8, there are push pins 11, straight push rods 13 and the protruding end of the core block 12 respectively. When the mold is opened, the top plate assembly 8 is subjected to external force and moves towards the fixed mold base 5, so that the push pins 11 push open the moving mold base 4 and its side structure. In this way, the moving mold core 401 is separated from the product part. At the same time, the straight push rods 13 push against the push block 15, and the core block 12 is also driven to push the product part out of the fixed mold core 501.

[0042] In addition, a core-pulling assembly 9 is provided on the outside of the mold, and a core-pulling post 901 is provided on the inside of the core-pulling assembly 9 and inserted into the cavity, so that the product part will have holes during injection molding. Before opening the mold, the core-pulling post 901 is removed so that the product part will not be damaged when opening the mold.
