Injection mold for plastic bent pipe

Abstract

The utility model discloses an injection mold of a plastic elbow, which relates to the technical field of injection molds and comprises a workbench, supports are fixedly connected to the front side and the rear side of the top end of the workbench, a plurality of sliding rods are fixedly connected between the two supports, a pair of mounting plates are arranged on the surfaces of the sliding rods, and a front mold is fixedly mounted at the rear end of the mounting plate on the front side. A rear mold is fixedly mounted at the front end of the rear side mounting plate, a plastic bent pipe is arranged in the rear mold, a first core pulling assembly is arranged at the rear end of the rear mold, a second core pulling assembly is arranged at the lower end of the rear mold, and cooling assemblies are arranged at the tops of the two mounting plates. By arranging the cooling assembly, after injection molding in the mold, the water pump is used for driving cooling liquid to flow into the circulating water tank in the mold, and the temperature of the mold is reduced in a heat conduction mode, so that raw materials in a molten state are helped to be cooled, solidification of the raw materials is accelerated, the waiting time is shortened, and the production efficiency of plastic bent pipes is improved.
