The cooling system with the fins and forced convection for injection molds for thermoplastics

摘要

The cooling system with the fins and forced convection for injection molds for thermoplastics, the present invention relates to a cooling system for injection molds for thermoplastics.The system consists of heat sink type fins, located on the fixed and movable mold parts and fans positioned over the fins with the purpose to promote the removal of heat during the cycle of injection molding. The removal of heat of the mold is carried out by use of the The fins with the objective of increasing area of heat exchange.The use of ventilators increases the coefficient of heat transfer by forced convection, preventing the withdrawal of heat by conduction and convection only occurs naturally.
