When the fixing bolts 118 are loosened The upper mold 110 and the lower mold 109 are stretched apart by the elastic properties of the insert mold assembly to expand the total height of the upper mold 110 and the lower mold 109. When locking the upper mold 110 and the lower mold 109, the fixing bolts 118 are locked to lock and squeeze the upper mold 110 through the fixing bolts 118, and the elastic force of the insert mold assembly is balanced so that the upper mold 110 and the lower mold 109 can reach a suitable position.

When the fixing bolt 118 is loosened, the elastic force of the two springs 111 pushes the upper mold 110 and the lower mold 109 to adjust the upper mold 110 and the lower mold 109. For the purpose of the total height of the lower mold 109, since the performance of the two springs 111 is consistent, the adjustment spacings of the adjustment card 114 and the adjustment ring 115 are the same spacing, and the second servo motor 105 drives the electric drive screw 104 to rotate forward or reverse, thereby driving the electric drive platform 103 to move forward or reverse, and correspondingly drives the installation shaft 106 and the rotating mold 107 to move, the installation shaft 106 installs the rotating mold 107, and the rotating mold 107 assists in clamping and auxiliary transmission of the workpieces driven by the upper mold 110 and the lower mold 109.
