Fast energy-saving thermal-forming cold-setting die assembly

Abstract

The invention discloses a rapid energy-saving thermoforming cold-setting mold set, which includes upper and lower mold sets with the same structure, wherein the upper mold set includes an inner upper mold and an outer upper mold, the lower mold set includes an inner lower mold and an outer lower mold, and the upper mold The hollow cavity formed between the mold group and the lower mold group is the working cavity. The inner mold is set in the groove of the outer mold, and the two are fixed by screws. There is a heat conduction and cooling cavity between the inner and outer molds. The two ends of the cooling cavity are respectively the inlet of the cold and heat source and the outlet of the cold and heat source, and the back of the inner mold is equipped with fin-shaped heat conduction and cooling sheets, and at least one layer of heat insulation board is added at the position of the inner cavity of the outer mold; the present invention The mold set and the general mold are operated under the same design of heat source and cold source equipment, which achieves more efficient production capacity and lower energy consumption than the general mold. This inventive mold set can speed up the heating and cooling of the mold, reducing Reduce energy consumption and increase production speed.

Description

technical field [0001] The invention relates to a mold, in particular to a rapid energy-saving thermoforming cold-setting mold set. Background technique [0002] Most of the existing molds on the market are resistance heating conduction molding machines, and the molds of this molding machine are double-mode closed, and the bottom of the upper and lower molds is thickened with drilling holes for heating and cooling. In the process of heating or cooling, due to the small heat conduction area in the mold drilling and the non-directional heat conduction, a large amount of energy is lost and it is impossible to save energy. Also, because the heating or cooling cannot be directional, the heating and cooling speed is slow, so the production The product has defects such as long time, high energy consumption, and slow cooling rate, resulting in high defect rate of cold setting. Contents of the invention [0003] The present invention provides a rapid energy-saving thermoforming co...
