The lower end of the upper mold base is provided with an upper mold, and the upper end of the upper mold is provided with a connecting block. The connecting block is provided with a connecting plate. The upper mold is connected to the upper mold base through the through groove via the connecting block. Then, the connecting plate on the connecting block is placed in the first groove. Then, the upper mold is rotated to fix it to the upper mold base. Then, it is fixed a second time by the hooks on the left and right sides. The distance between the hooks can be adjusted according to the size of different upper molds. After adjustment, the nuts are tightened to fix it.

[0003] The applicant discovered that existing patents require the upper mold base to be made larger in order to accommodate larger upper molds, resulting in heavy overall weight and high cost. Utility Model Content
