[0034] The lower template 3 is provided with a slot 52, and the connecting block 51 is inserted into the slot 52. The slot 52 makes the connecting block 51 more securely installed and also facilitates the positioning of the connecting block 51.
[0035] The lower mold base 2 is also provided with a support assembly 6 that can abut against the side top block 421 and the connecting block 51 when the upper mold plate 4 and the lower mold plate 3 are closed. The support assembly 6 includes multiple support frames 61 disposed on the lower mold base 2. The multiple support frames 61 are disposed on the periphery of the lower mold plate 3, and each support frame 61 is connected to a support plate 62 that can abut against the side top block 421 and the connecting block 51. The support plate 62 is positioned to abut against the side top block 421 and the connecting block 51, preventing mold penetration. The height of the support frame 61 can be changed to accommodate support plates 62 of different heights, thus broadening its application range.
