When the force spring 26 acts, the movable positioning plug rod 24 is driven to reset, so that one end of the movable positioning plug rod 24 can be inserted into the inside of the movable mounting rod 14, and the movable mounting rod 14 and the fixed mounting frame 13 are connected and fixed. Then the fixed connecting pipe 12 is connected to the vacuum pump, and the vacuum treatment is performed between the first mold 1 and the second mold 2. At the same time, under the action of the gas one-way valve 11, when the pump stops working, the vacuum state between the first mold 1 and the second mold 2 can be maintained. Then the electric control valve 6 is opened, so that under the atmospheric pressure and the cooperation between the injection molding machine feed pipe 7 and the injection molding machine, the raw material can flow stably between the first mold 1 and the second mold 2, thereby performing molding processing on the parts. After the molding processing is completed, the first mold 1 and the second mold 2 are separated.
