The invention relates to a heating mechanism inside a steel skeleton mould cavity of a PE (Poly Ethylene) pipe mould, comprising a mould cavity frame, wherein a mould cavity is arranged in the mould cavity frame and is internally provided with a steel skeleton; and the mould cavity frame is provided with a steel skeleton heating mechanism. The heating mechanism is characterized in that the steel skeleton heating mechanism comprises an inclined guiding slideway, wherein the inclined guiding slideway is arranged on the outer wall of the mould cavity frame and provided with a guiding slide block; the guiding slide block is provided with a heating support; a heating element is connected below the heating support; the end part of the inclined guiding slideway is provided with an oil cylinder; and a piston rod of the oil cylinder is connected with the heating support and drives the heating element positioned below the heating support to be in contact with the steel skeleton. By adopting the heating mechanism, the steel skeleton is placed in the mould cavity for automatic heating without manual operation, therefore manual cost is saved; and in addition, especially the heating element can be adhered to the steel skeleton so as to ensure uniform heating and enhance the supplementary fit of the steel skeleton and injection molding raw materials, therefore the quality of products is ensured.
Description
technical field [0001] The invention relates to a heating mechanism in a mold cavity of a PE pipe fitting mold steel skeleton, which belongs to the field of plastic molds. Background technique [0002] Due to the difference in product functions and uses, steel skeletons are added to PE pipe fittings to improve product strength and prevent product deformation coefficients. The steel frame needs high-frequency heating before injection molding to ensure that the temperature difference with the injection molding temperature is reduced, and the product will not shrink and deform due to the temperature difference after the product is wrapped with the steel frame by injection molding. In the prior art, the steel skeleton is mostly heated outside the cavity of the injection mold. Due to the high temperature after heating, it cannot be directly operated manually. It can only be put into the cavity by manipulators. The disadvantage is that the product cannot be positioned accurately, ...
