Electrical heating rapid heat cycle injection mold

Abstract

The invention relates to an electrical heating rapid heat cycle injection mold. The electrical heating rapid heat cycle injection mold comprises an electrical heating type cavity plate and an electrical heating core plate, and cooling plates which are respectively matched with the electrical heating type cavity plate and the electrical heating core plate, wherein the back of the electrical heating type cavity plate and the electrical heating core plate are provided with grooves, and a special clamp device and a method are utilized to arrange and fix a heating device in the grooves; grooves are formed in the surfaces of the cooling plates, are matched with the back of the cavity plate to form cooling pipelines; a sealing device is arranged among the electrical heating type cavity plate and the electrical heating core plate and the cooling plates respectively corresponding to the electrical heating type cavity plate and the electrical heating core plate; a temperature measuring device is arranged on the electrical heating type cavity plate and the electrical heating core plate; and the temperature measuring device, the heating device, the cooling device and a temperature control device are connected. The electrical heating rapid heat cycle injection mold provided by the invention has the extruding advantages that the heating cooling efficiency is high and uniform, and the surface of the three-dimensional complicated shape mould cavity is rapidly uniformly heated and cooled.
