Background
After the steel skeleton plastic composite pipe is fed and discharged from a production line, warp and weft steel wires are respectively exposed at two ends of the pipe, so that the pressure bearing and the integrity of the pipe are influenced. The best solution at present is to place the two ends of the pipe in a sealing mould on an injection molding machine for high-pressure injection molding and plugging. In the process of high-pressure injection molding of the pipe in the mold, because the end part bears high pressure, if the pipe cannot be clamped, the pipe can be withdrawn from the mold. For this purpose, the front end of the die is designed with a tooth-shaped clamping pipe to ensure that the pipe cannot be withdrawn from the die in the high-pressure injection molding process. The original sealing mould is divided into an inner clamping position and an outer clamping position, and the inner clamping position and the mould cavity are integrated. The outer clamping position can be replaced according to the different outer diameter sizes of the pipes, but the inner clamping position is integrated with the die cavity, so that the inner clamping position cannot be replaced, and the structure cannot solve the problem that the two pipes with different outer diameter sizes, namely a low-pressure pipeline and a high-pressure pipeline, are sealed on the same pair of dies.
