A low-pressure casting mold for truck aluminum wheels

Abstract

The invention provides a low-pressure casting mold for aluminum wheels of trucks. The low-pressure casting mold comprises an upper mold, a lower mold and side molds. An ejector rod plate, an ejector rod press plate and an ejecting mold plate are sequentially arranged at the upper end of the upper mold, the lower mold is arranged at the lower end of the upper mold, the side molds are arranged on sides of the upper mold, an upper ceramic template is arranged in the center of the upper mold, the upper mold is provided with a venting plug, the lower mold is provided with a lower ceramic pouring gate, and a heating resistor and a thermocouple are arranged at throat and neck positions of the lower mold. By the aid of the low-pressure casting mold for the aluminum wheels of the trucks, closing and stripping circulation can be realized, and the low-pressure casting mold has the advantages of low investment and cost and capability of being quickly used in production. In addition, investment on a blank stage is only one-fifth of that of a rotary forging process, and production cost of the low-pressure casting mold is only one-third of that of the rotary forging process. Besides, the low-pressure casting mold for the aluminum wheels of the trucks is provided with an annular runner, a center hole of a blank can be cast, the usage amount of molten aluminum of the blank is reduced by 4 kilograms, and heat load of a casting system is reduced.

Description

technical field [0001] The invention relates to a mold, in particular to a low-pressure casting mold for an aluminum wheel of a truck. Background technique [0002] The load of aluminum wheels of trucks is very large, four times that of passenger cars. In order to achieve the required metallurgical quality, there are high requirements for casting technology and casting equipment. The low-pressure casting truck aluminum wheel process is a production method for this type of product. Compared with the forging process, it has the advantages of less investment, low cost, and quick start-up. However, the design of low-pressure casting equipment determines the production quality and production cost of truck aluminum wheels. Therefore, how to make the low-pressure casting molds of truck aluminum wheels convenient for the production of truck aluminum wheels and improve the production quality of truck aluminum wheels Production efficiency, cost saving, and production efficiency im...
