[0039] When the utility model is working: the controller 16 controls the two first cylinders 23 to synchronously push the connecting rod 22 to move upward, thereby driving the upper mold assembly 3 and the lower mold base 11 to close. During the closing process of the upper mold assembly 3 and the lower mold base 11, the positioning column 35 is inserted into the positioning hole 41. After the positioning column 35 is inserted into place, the first cylinder 23 continues to push the upper mold shell 30 and the upper mold base 31 downward, so that the push plate 33 on the positioning column 35 moves upward to compress the reset spring 36, and the bottom of the push rod 32 on the push plate 33 and the upper mold The inner top wall of the seat 31 is flush with the inner top wall of the seat 31.

When the temperature inside the mold reaches the preset demoulding temperature, the controller 16 controls the two first cylinders 23 to move, push the connecting rod 22 to move downward, thereby driving the support frame 19 to move downward, so that the sealing column 18 slides downward in the vent hole 17, so that the vent hole 17 and the air inlet 20 are connected, which is convenient for air to enter the interior and prevents the internal negative pressure from causing The mold cannot be demoulded. At the same time, the first cylinder 23 continues to push the connecting rod 22, so that the upper mold base 31 and the lower mold base 11 are separated, and the positioning column 35 slides out of the positioning hole 41, thereby releasing the limit on the push plate 33, and the reset thrust of the reset spring 36 pushes the push plate 33 to reset, thereby driving the push rod 32 to move downward to eject the molded product from the inside of the upper mold base 31. After the mold opening is completed, the controller 16 automatically starts the second cylinder 39 to drive the push rod 40 to move upward, thereby ejecting the molded product from the inside of the lower mold base 11 and completing the demoulding.
