摘要： An injection nozzle for injection molding machines with a valve system having a piston movably positioned around the top end portion of a nozzle body. A guide slot is formed at the top end portion of the nozzle body, and movably receives a pin actuating bar, integrated with a valve pin-of the valve system, and so the pin actuating bar is vertically and precisely movable under the guide of the guide slot. The valve pin is thus precisely movable in the nozzle body in a linear vertical direction without failure. The nozzle is also preferably used for producing large-scaled products or small-scaled products, thus have an improved compatibility. The nozzle is preferably used in a stack molding process. In addition, even when a manifold thermally expands due to a high temperature molten plastic material and is undesirably changed in position, the valve system is continuously operated without being stopped, thus allowing the injection molding process to be continued for a lengthy period of time.
