The invention discloses a low-pressure water cooling wheel hub mold. The low-pressure water cooling wheel hub mold comprises a bottom plate; a mold body is installed on the upper end surface of the bottom plate; the mold body comprises a top mold, a bottom mold and side molds, the top mold, the bottom mold and side molds cooperate with one another, the inner walls of the side mold and the upper end surface of the bottom mold cooperate to form a cavity, the top mold is arranged in the cavity and matched with the inner walls of the side mold and the upper end surface of the bottom mold to form an injection molding cavity of a wheel hub, and the bottom mold is provided with a sprue gate; a water cooling device comprises a cooling water circulator, cooling water channels, a water inlet pipe and a water outlet pipe, the top mold, the bottom mold and the side molds are all internally provided with the cooling water channels, one ends of the cooling water channels communicate with a water outlet of the cooling water circulator through the water inlet pipe, and the other ends of the cooling water channels communicate with a water inlet of the cooling water circulator through the water outlet pipe. According to the low-pressure water cooling wheel hub mold, fixing bolts are sleeved with elastic gaskets, the precision of an injection molding piece is ensured, and the product quality is guaranteed; and a heat preservation device arranged at the sprue gate can ensure the sprue gate to keep the high temperature, and thus, injection molding liquid smoothly enters the cavity.
Description
technical field [0001] The invention relates to the technical field of mechanical casting, in particular to a low-pressure water-cooled hub mold. Background technique [0002] As one of the most important moving parts of a car, the wheel hub has high requirements on its performance, weight and service life. Wheels are generally produced by casting, and mold cooling is an important part of the production process. At present, the cooling methods and cooling devices used in casting hub molds are not accurate, and the heat transfer efficiency is relatively low. It is difficult to effectively control the flow direction of the cooling medium and the temperature field of the mold, which will affect product quality. Contents of the invention [0003] In view of the deficiencies of the above technologies, the object of the present invention is to provide a low-pressure water-cooled hub mold. [0004] The purpose of the present invention is achieved by such technical scheme, a kin...
