Steam heating type fast heat-circulation injection mould

Abstract

The invention relates to a steam heating type fast heat-circulation injection mould which comprises a steam heating type sectional cavity plate and an electric heating type sectional core plate, wherein the fast heat-circulation injection mould further comprises a thermal insulation device and a support device which are respectively matched with the steam heating type sectional cavity plate and a steam heating type sectional core plate. The back surfaces of the steam heating type sectional cavity plate and the steam heating type sectional core plate are provided with grooves, the grooves are matched with the surface of the thermal insulation device to form a sealed pipe hole, so as to be used as a heating device and a cooling device. Sealing devices are respectively arranged between the steam heating type sectional cavity plate and the corresponding thermal insulation device and between the steam heating type sectional core plate and the corresponding thermal insulation device. Temperature measurement devices are respectively installed on the steam heating type sectional cavity plate and the steam heating type sectional core plate. The temperature measurement devices, the heating device and the cooling device are connected with a temperature control device. The steam heating type fast heat-circulation injection mould has the outstanding advantages of high heating and cooling efficiency and heating uniformity, so that the surface of a sectional cavity of a three-dimensional complex-shape mould can be uniformly and quickly heated or cooled.

Description

technical field [0001] The invention belongs to the technical field of injection molding in the subject of material processing, and in particular relates to a steam-heated rapid thermal cycle injection mold. Background technique [0002] In recent years, with the development of 3C, automobile, aerospace and other industries, plastic products continue to develop in the direction of more beautiful appearance, lighter weight and more precise structure, so as to meet people's needs for energy saving, environmental protection, comfort and beauty of industrial products. Require. As one of the most widely used plastic processing methods, injection molding is facing increasingly severe challenges and requires continuous technological innovation to meet the needs of market development. Since the traditional injection molding process adopts the mold temperature control method based on continuous cooling, the melt will condense prematurely during the filling process, resulting in defe...
