ABSTRACT:
The invention of this patent is to be used in molding applications. An external applied force causes an actuator rod to move in a linear motion. This motion causes two platens to move simultaneously together to form a clean, even mold. The platens move linearly on tie bars, which guide the linear movement of the platens. Linkage arms are mounted on a mounting plate and the linkage arms are connected to the platens. This allows the clamping and applied force stresses on the platens to be dependent on the mounting plate, rather than the tie bars. The platens travel at the same speed and distance in relation to each other. The result is an evenly produced part that comprises two die or mold halves which are perfectly centered.
