The injection molding groove one side of the top die is provided with a demoulding component moving groove, the shape of the demoulding component moving groove is equal to the cross section shape of the sliding rail, the sliding rail is arranged in the demoulding component moving groove, one end of the sliding rail is provided with a cutter, the other end of the sliding rail is provided with a limiting block, the cutting edge of the cutter faces the middle part of the top die, the cutter is driven to move through the movement of the sliding rail, and when the injection molding top die moves upwards, the sliding groove moves through a sliding groove driving machine, so that the cutter cuts off the flow passage, and demoulding is completed.
The beneficial effects are that:
the injection molded part is taken out through the mold above the top mold, so that the problem of demolding in the injection mold is conveniently realized, and the runner and the injection molding body can be cut off through the cutters on the side edges, so that the injection molded part is taken out more conveniently, and demolding operation is more conveniently performed.
The demolding and pulling-up of the injection molding part through the top mold can be realized through the top mold capable of moving in one direction, and then the demolding operation of separating from the runner in the later stage is completed.
The material solidified at the injection port is heated when the demolding is finished and the injection port is ready for re-injection through the injection port with the heating coil, so that the injection port can circulate, and the injection is performed again.
The movement of the sliding rail drives the movement of the cutter, and when the injection molding top die moves upwards, the sliding groove moves through the sliding groove driving machine, so that the cutter cuts off the flow passage, and the demolding is completed.
