The top of the slider 12 is fixedly installed on the bottom of the U-shaped seat 2. When the second motor 10 is started, the output shaft of the second motor 10 drives the reciprocating screw 11 to rotate. The rotation of the reciprocating screw 11 drives the slider 12, the U-shaped seat 2, the punch 3, and the die 4 to move back and forth, generating vibrations for the punch 3, the die 4, and the hot-melt plastic in their cavity. The air in the cavity and the hot-melt plastic is removed by vibration, and the hot-melt plastic is driven to adhere tightly to the cavity, thereby improving the molding quality of the decorative cover.

[0030] Working principle: Through the injection molding machine, the hot melt plastic is injected into the cavity of the punch 3 and the die 4 through the injection port 5, and then the second motor 10 is started. The output shaft of the second motor 10 drives the reciprocating screw 11 to rotate. The rotation of the reciprocating screw 11 drives the slider 12, the U-shaped seat 2, the punch 3, and the die 4 to move back and forth, generating vibrations on the punch 3, the die 4, and the hot melt plastic. The bubbles in the cavity and the hot melt plastic are removed by vibration. By starting the water pump 17, the coolant is extracted by the water pump 17, and the coolant passes through the water pump 17 and the delivery hose. 18. The connecting hose 19 can be injected into the cooling cavity of the punch 3 and the die 4 to cool the punch 3, the die 4 and the hot-melt plastic, driving the hot-melt plastic to form a decorative cover. Then, by starting the first motor 7, the output shaft of the first motor 7 drives the bidirectional threaded rod 8 to rotate. The rotation of the bidirectional threaded rod 8 drives the two threaded blocks 9, the punch 3 and the die 4 to separate. Since the movable rod 13 pushes the connecting plate 14 and the push rod 15, the push rod 15 can push the decorative cover from the cavity of the punch 3 and the die 4, thereby realizing automatic stripping of the decorative cover.
