Abstract

A valve-gated injection moulding device, wherein the actuating device of the valve pin comprises a first arm and a second arm. The first arm is hingingly connected in a first end tot he rearward end of the valve pin. The second end of the first arm is hingingly connect to a displacement device, which can be moved along a radial displacement trajectory. The second arm is with its first end hingingly connected to the midpoint of the first arm. The second end of the second arm is connected in a fixed hinge point to a support of the injection moulding device. In this way, using a radial actuating device, only an axial force is exerted on the valve pin. The stroke of the valve pin can easily be adjusted from outside the mould by increasing or decreasing the stroke of the piston. The actuating device is relatively small, and does not require a large re-routing of the melt passage as it is positioned radially outwardly from the longitudinal center line of the valve pin. it can be operated from outside the mould. The adjustment of the height of the valve pin can take place outside the mould.
