Abstract
Heating device for locally heating of an injection mold cavity wall, comprising: a base plate, an actuator located on the base plate, to perform a linear movement; a heated stamp connected to the actuator and driven by the actuator, to perform a linear movement in direction to and from the injection mold cavity wall; wherein the heated stamp is located below the base plate and the actuator is located on top of the base plate, and wherein the base plate comprises an opening through which a pin extends for transferring the linear movement from the actuator to the heated stamp.
Claims12
A heating device for locally heating an outer surface of a wall of an injection mold having a plurality of gates, comprising:
- a hot runner system including a manifold having a system of channels for distributing molten plastic from an injection molding machine to the plurality of gates;
- a base plate;
- an actuator located on the base plate to perform a linear movement;
- a heated stamp connected to the actuator and driven by the actuator to perform a linear movement of the heated stamp toward and into physical contact with the outer wall of the mold remote from the gates to conduct heat through the wall of the mold to a mold cavity, and to perform a linear movement of the heated stamp away from and out of contact with the outer wall of the mold to allow cooling of the mold cavity wall;
- wherein the heated stamp is located below the base plate and the actuator;
- wherein the base plate comprises an opening through which a pin extends for transferring the linear movement from the actuator to the heated stamp;
- and
- wherein the base plate is integrally formed in the manifold of the hot runner system, so that it is part of the manifold.
