Automobile hub pouring system and pouring method

Abstract

The invention discloses an automobile hub pouring system and a pouring method and relates to the technical field of hub casting. The automobile hub pouring system comprises a first mold cavity, a second mold cavity and a public mold cavity located between the first mold cavity and the second mold cavity. The first mold cavity communicates with a first mold above the first mold cavity through a liquid lifting pipe. The second mold cavity communicates with a second mold above the second mold cavity through a liquid lifting pipe. The public mold cavity communicates with the first mold cavity and the second mold cavity through liquid supplementing ports. The upper portion of the public mold cavity is provided with a feeding inlet, and a heater and a temperature detector are arranged in the public mold cavity. The invention further discloses the pouring method for the automobile hub pouring system. The pouring method comprises the steps of feeding, liquid supplementing, liquid lifting, molding filling pressurizing, pressure maintaining and pressure relief demolding. According to the automobile hub pouring system and the pouring method, melting liquid is supplemented into the first mold cavity and the second mold cavity by arranging the public mold cavity, the generating probability of oxide is greatly reduced, the influence of the liquid supplementation process on a hub is eliminated, uninterrupted production of hub casting is effectively achieved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of wheel hub casting, in particular to an automobile wheel casting system and a pouring method suitable for the automobile wheel casting system. Background technique [0002] Wheels are one of the parts related to automobile safety, which can be divided into steel wheels and aluminum alloy wheels. Compared with steel wheels, aluminum alloy wheels have light weight, high strength, good braking balance performance, high precision, and heat conduction. There are many advantages such as good performance and low fuel consumption of automobiles, so aluminum alloy wheels have broad application prospects. [0003] The manufacturing technology of aluminum alloy wheels mainly includes casting and forging, among which the widely used casting technology is divided into gravity casting and low pressure casting. The manufacturing process of the former is simple, you only need to pour the liquid alloy into the mold for co...

Problems solved by technology

Since the melt will lose heat during the replenishment process, it is necessary to heat the melt for a period of time before using it after replenishing the liquid; and when the liquid is replenished, the aluminum liquid is in contact with the air, which will produce more oxides. The impact is that the oxides, slag and other substances in the mold cavity need to be cleaned out before casting. This process is time-consuming and laborious, which greatly reduces production efficiency and is not conducive to the continuous production of aluminum alloy wheels.
