[0029] The frame structure comprises a power slide rail frame 1 , the inner side of which is slidably connected with a power mounting base 3 , and the lower end of the power slide rail frame 1 is fixedly welded with a base 6 .

[0030] The cooling assembly includes a mold outer shell 12, a cooling pipe connecting pipe 11 and an upper mold 7. The lower mold 5 is pressed onto the bottom of the upper mold 7. The side and bottom of the lower mold 5 are surrounded by cooling pipes 2. The side and top of the upper mold 7 are provided with cooling pipes 2. The front of the lower mold 5 is provided with a liquid outlet 8. The front of the upper mold 7 is provided with a liquid inlet 9. Two injection holes 10 are provided on the top of the upper mold 7.

The cooling pipe connecting pipe 11 of the upper mold 7 and the cooling pipe connecting pipe 11 of the lower mold 5 are sealed and connected via the cooling pipe connector 4.

[0031] In this embodiment, the length of the cooling pipe connecting pipe 11 is adapted to the moving height of the upper mold 7 , and the interface directions of the two cooling pipe connectors 4 are opposite to prevent the interface from being blocked during the movement of the upper mold 7 .

[0032] In this embodiment, the upper mold 7 is fixedly mounted on the bottom of the power installation base 3 , so that the upper mold 7 can move up and down based on the power installation base 3 .
