As shown in fig. 10-12, the air bag 25 and the inflation assembly are further included, the air bag 25 is wrapped on the outer side of the connecting rod 5, the magnetic block 4 and the connecting rod 5 are internally provided with an air supply channel 26, the air supply channel 26 is L-shaped, the right end of the air supply channel 26 is exposed out of the right side surface of the magnetic block 4, the upper end of the air supply channel 26 is communicated with the air bag 25, the inflation assembly injects air into the air bag 25 through the air supply channel 26 so that the air bag 25 is inflated to be attached to the inner wall of the metal insert, the inflation assembly comprises an electric push rod II27, a hollow frame 28, a connecting pipe 29 and a piston plate 30, the electric push rod II27 and the hollow frame 28 are connected to the bottom surface of the accommodating groove 205, the hollow frame 28 is positioned on the left side of the electric push rod II27, the connecting pipe 29 is connected to the left side of the hollow frame 28, the left end of the connecting pipe 29 is positioned in the air supply channel 26, the piston plate 30 is slidingly connected to the hollow frame 28, and the right side of the piston plate 30 is connected with the telescopic rod of the electric push rod II 27.
The common metal inserts are provided with nuts and bushings, as the inner wall of the nuts is provided with screw grooves, and the screw hole ends of the nuts are subjected to chamfering treatment so as to be convenient for installing the nuts and the screws, when the nut is buried, even if the connecting plate 6 can block the left side surface of the nuts, the connecting plate 6 cannot be attached to the left side surface of the nuts, so that plastic raw materials in a cavity of the female die 1 possibly enter the screw grooves of the nuts through the screw hole ends of the nuts, when the nut is buried, the air bag 25 moves to the inner side of the nuts along with the connecting rod 5, then the expansion rod of the electric push rod II27 can be controlled to extend, the piston plate 30 is driven to move leftwards in the hollow frame 28, the piston plate 30 can squeeze air in the hollow frame 28 into the connecting pipe 29, the connecting pipe 29 can inject the air into the air bag 25, the air bag 25 can expand to attach the screw grooves of the inner wall of the nuts, the screw grooves of the inner wall of the nuts can be blocked, plastic raw materials in the cavity of the female die 1 can be prevented from entering the screw grooves of the inner wall, after the plastic products are molded, the piston rod of the electric push rod II27 can be controlled to be shortened, the piston plate 30 can be driven to move leftwards in the hollow frame 28, and the hollow frame 28 can be restored by resetting the air bag 25.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention.
