The electric push rod 3 drives the driving block 4 at the left end to move, and at the same time drives the driving block 4 at the right end to move through the connecting rod 5. When the driving block 4 moves, it will push the two connecting rods 6 connected to it to move. The connecting rods 6 push the support block 9, the cross plate 7 and the limit plate 10 to move in the opposite direction. When the limit plate 10 moves in the opposite direction, it will push the battery middle cover injection mold to move, limit the mold inside the base 1, and the motor 16 can drive the lead screw 14 to rotate.
