After the injection molding, the valve stem 20 is pushed by the air pressure sister 30 and the injection port 102 is closed. Because the front end of the valve stem 20 is pushed to the position where the M reaches the injection port 601, it will be left or protruding residues or dents on the plastic injection molded products. When the different molds are to be injection molded, the front end of the valve stem 20 must be adjusted to a position that can be pushed to the injection port 6 0 1 of the mold. In the past, the adjustment system of the forward and backward position of the front end 20 of the valve stem was to disassemble the cylinder seat. It is not only troublesome, time-consuming and labor-intensive, but also the lack of improvement that the industry knows and needs to be improved. [Content] The purpose of this creation is to solve the lack of time-consuming, troublesome and time-consuming adjustment of the conventional plastic injection of the hot nozzle valve stem. The lack of Θ450 M242352 provides a simple adjustment structure of the plastic injection of the hot nozzle valve stem. The creator of the Department of Structures has gained many years of research and design in the practical experience and continuously explored the improvement. It mainly includes the main components such as the slider, the action rod and the adjustment screw, and an opening is set horizontally behind the steam seat. Rail, the open rail
