[0002] At present, electronic products are updated faster and faster. Electronic products need electrical energy to provide power. The power adapter serves as a connection carrier for electronic products, connecting electrical energy to electronic products. The shell of the power adapter is also very important.

[0003] In the prior art, a method of injecting glue into the product by using a large sprue submerged flat top is adopted. The large sprue submerged flat top mold is divided into an upper fixed mold and a lower movable mold. The plastic enters from the glue mouth sleeve channel. After the product is filled, the movable mold moves to open the mold, and the ejection device ejects the product and the sprue material, and then the sprue material is cut off after being taken out manually. The production efficiency is low and the labor cost is high. Utility Model Content

[0014] When the upper mold moves upward, it drives the second rack upward. After the second rack moves to a certain position, it drives the second gear to rotate. The rotation of the second gear drives the third transmission wheel and the fourth transmission wheel to rotate, and then drives the bidirectional screw to rotate.

[0015] Preferably, the outer wall of the bidirectional screw is movably connected to the sliding block through a thread, the upper end of the sliding block is rotatably connected to the fixed block through an extrusion rod, the fixed block is fixedly installed on the bottom end of the push plate, and the upper end of the push plate is fixed with a first push rod and a second push rod, the first push rod extends to the inside of the mounting ring, the second push rod extends to the inside of the molding groove, and the length of the second push rod is shorter than the first push rod.
