[0006] Furthermore, a U-shaped groove is provided in the middle of the lower mold frame, the lower mold core is set in the U-shaped groove, and a central positioning block is installed on one side of the lower mold frame. The central positioning block passes through one side of the lower mold core by bolts and extends into the U-shaped groove.

[0007] Furthermore, multiple mold frame pressure plates are installed on the lower mold frame, and the mold frame pressure plates are respectively located at the four vertices of the lower mold frame.

[0008] Furthermore, a plurality of lifting eye screws are installed at the bottom of the upper mold frame, and the lifting eye screws are arranged symmetrically to each other.

[0009] Furthermore, the upper mold frame is provided with multiple bolt slots, and T-slot bolts are respectively installed in the bolt slots.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. This utility model uses a lower mold frame made of tempered material, which is rough-machined, tempered, and then fine-machined to eliminate stress and ensure quality and precision.

[0012] 2. This utility model can quickly position the mold core by setting a central positioning block, thus ensuring the stability of the mold core. Attached Figure Description
