The invention belongs to the field of plastic part processing, and particularly relates to an injection molding device easy to demold. The injection molding device easy to demold comprises a lower mold unit and an upper mold unit matched with the lower mold unit, and is characterized in that the lower mold unit comprises a supporting table; a lower mold is installed at the top end of the supporting table and provided with a lower mold groove, and a heat dissipation shell located on the periphery of the lower mold and capable of wrapping the lower mold is further installed on the supporting table; and the bottom end of the supporting table is connected with a stand column, the bottom end of the stand column is connected with a bottom plate, a water tank is installed on the bottom plate andfurther provided with a water inlet pump, and the water outlet end of the water inlet pump communicates with a water conveying pipe communicating with a lower mold heat dissipation cavity. According to the injection molding device easy to demold, under the action of a movable block elastic piece, the top end face of a lower mold movable block is flush with the groove bottom face of a lower mold groove, and therefore injection molding operation can be conducted; and under the action of a movable block upward-ejecting driving device and an upward-ejecting rod, the lower mold movable block can move upwards relative to the lower mold to eject out an injection molding semi-finished product, and therefore demolding operation can be conveniently completed.
Description
technical field [0001] The invention relates to the technical field of plastic parts processing, in particular to an injection molding device that is easy to demould. Background technique [0002] Plastic products are a general term for household and industrial products processed from plastic as the main raw material. They can be made by injection molding, blister molding and other processes. Taking the injection molding process as an example, the existing molding device has the following problems: 1. Dividing the mold is inconvenient. Generally, multiple fasteners need to be disassembled when the mold is divided, and the operation is cumbersome; 2. The cooling effect is poor, resulting in a long cooling cycle; 3. It is inconvenient to remove the mold after parting, and the work efficiency is low. Contents of the invention [0003] The object of the present invention is to provide an injection molding device that is easy to demould, which solves the problems of inconvenie...
