Abstract:
1. An injection molding apparatus comprising: a first mold defining a passage therein; a second mold engaging with the first mold, the first mold and the second mold cooperatively defining a molding chamber therebetween adapted to receive injected molten material therein; working fluid received in the passage of the first mold; and a thermostat assembly comprising a thermal conductive member thermally contacting the first mold and directly contacting the working fluid, a heating and cooling device, and a controller detecting a temperature of the first mold and the second mold and controlling the heating and cooling device to heat or cool the working fluid to adjust a temperature of the working fluid to alter a cooling speed of a desired product received in the molding chamber via heat exchange between the thermal conductive member and the working fluid.
