Problems solved by technology
[0003] It is necessary to keep the injection temperature within an appropriate range during injection molding on the injection mold. If the temperature is too high, it will easily make the injected molten material not easy to cool and shape, resulting in the molded clothes hanger is also prone to dent deformation, and the current injection molding, waiting When the temperature on the mold rises to a certain height, a large amount of heat will be released from the mold at this time. Since there is no device for recycling heat on the mold at present, the heat will be lost in vain.

The waste heat utilization protection type plastic clothes hanger injection mold comprises a lower mold body and an upper mold body, a feeding pipe is arranged on the upper mold body, a protection mechanism is arranged on the upper mold body and comprises a circular groove formed in the side wall of the upper mold body, a protection disc is rotationally connected to the inner wall of the circular groove, and a first plate is fixedly connected to the inner wall of the circular groove; a second plate is fixedly connected to the side wall of the protection disc, the first plate is connected with the second plate through a conductive spring, a thermistor is installed at the bottom of the circular groove and is in coupling connection with the conductive spring, and a guide rod is fixedly connected to the side wall of the protection disc. Through the arrangement of the protection mechanism, when the guide rod rotates to make contact with the resistor strip, the resistance, connected into a circuit, of an external heating source is increased, the heat generated by the external heating source is reduced, then the lower mold and the upper mold are actively cooled, and the situation that the temperature of the lower mold and the upper mold is too high, and the quality of the formed plastic clothes hanger is affected is avoided.
Description
technical field [0001] The invention relates to the technical field of injection moulds, in particular to an injection mould of a waste heat utilization protection type plastic clothes hanger. Background technique [0002] At present, most of the hangers are made of plastic, so the production of the hangers needs to be injection-molded by an injection mold. [0003] When injecting on the injection mold, it is necessary to keep the injection temperature in a suitable range. If the temperature is too high, it will easily make the injected melt not easy to cool and shape, and the molded hanger is also prone to depression and deformation. When the temperature on the mold rises to a certain height, a large amount of heat will be released from the mold at this time. Since there is no device for recycling heat on the mold at present, the heat is wasted in vain. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to solve the problems existing in the prior a...
