Hub gravity casting four-opening pressurizing die

Abstract

The invention discloses a hub gravity casting four-opening pressurizing mold in the field of hub intelligent manufacturing, which comprises an upper mold plate and a lower mold plate which are horizontally arranged, the lower mold plate is arranged on a base, a lower mold is arranged on the lower mold plate, and at least two inclined side opening guide rails are arranged on the lower mold plate corresponding to each side mold; side-opening driving mechanisms are arranged corresponding to the side dies, a plurality of vertical guide columns evenly distributed in the circumferential direction are arranged on the lower side of the upper die plate, the lower ends of the guide columns are fixedly connected with the upper die, the upper die, the four side dies and the lower die define a cavity, a horizontal ejector plate capable of moving up and down is arranged corresponding to the guide columns, and the horizontal ejector plate is fixedly connected with the upper die. The ejector plate is in transmission connection with a center lifting driving mechanism, a plurality of pressurizing ejector rods distributed at intervals in the circumferential direction are arranged on the lower side of the ejector plate, and a side air plug corresponding to the cavity is arranged at the lower end of each pressurizing ejector rod. By introducing air into the cavity, the internal structure of the hub casting cast by gravity is compacted, and the four side dies are opened at the same time, so that the efficiency is higher.

Description

technical field [0001] The invention belongs to the field of intelligent manufacturing of wheel hubs, and particularly relates to a four-open pressurized mold for gravity casting of wheel hubs. Background technique [0002] In the prior art, there is a low-pressure casting mold for automobile wheel hub, and its patent application number: 201821086473.8; application date: 2018-07-10; publication number: 208495761U; publication date: 2019-02-15; Side die, right die, upper die, cavity, bottom fixing frame, top fixing frame, shunt cone, sprue sleeve, liquid riser, left cooling fin, right cooling fin, rim cooling pipe, cooling pipe water inlet , Cooling pipe water outlet and cooling water channel, the upper mold, left mold, right mold and lower mold are combined to form the cavity of the wheel hub, and the bottom fixing frame and the top fixing frame are surrounded by the top of the corresponding mold joint. There is a boss at the position of the casting machine, and the bottom ...

AI Technical Summary

Problems solved by technology

The cooling fins, cooling pipes and cooling water channels of the mold can dissipate heat from the casting, but its disadvantages are: the aluminum water in the cavity is not pressurized, resulting in loose distribution of the aluminum liquid, and the resulting wheel hub casting is relatively loose in structure. The internal structure of the casting is not tight enough
