Low-pressure cantilever casting production line

Abstract

The invention discloses a low-pressure cantilever casting production line which comprises low-pressure casting gantry equipment (1-1), a sand core grabbing manipulator (1-2), low-pressure cantilever casting machines (1-3-1) , a feeding conveyer belt (1-4) and a finished product conveying belt (1-5) . Each low-pressure cantilever casting machine (1-3-1), a hydraulic device, a temperature maintaining furnace, an electric control cabinet, a hydraulic station, a mold opening and closing mechanism and the like form a casting unit (1-3). The low-pressure casting production line consists of a lineararray of four casting units. Almost all casting process actions can be completed in an unmanned environment, the low-pressure cantilever casting production line can provide a closed, dry and constant-temperature production environment, and the defect of relatively poor compactness of low-pressure casting products can be overcome. At the same time, low-pressure casting gantry equipment is used foroperating a plurality of sets of low-pressure cantilever casting machines with the advantage of long pressure maintaining cooling time in low-pressure casting. The compactness of the casting is improved, the off-line time of the finished casting is shortened, and the actual production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of modern mechanical design. Specifically related to the low pressure cantilever casting production line. Background technique [0002] With the rapid economic development, the manufacturing industry has an increasing demand for thin-walled alloy products. In particular, the automobile industry is accelerating the lightweight of the whole vehicle, and magnesium and aluminum alloys are favored by more and more automobile manufacturers. Among them, aluminum alloys have been widely used in the manufacture of auto parts. For example, most parts such as car wheel hubs, cylinder heads, and cylinder blocks are made of aluminum alloys. With the continuous improvement of the industrial level, more and more fields have new requirements for aluminum alloys. [0003] Low-pressure casting is a casting form in which the molten metal at high temperature is forced into the cavity against gravity through a liquid riser after applyi...

AI Technical Summary

Problems solved by technology

Due to the limitations of its own structure, the traditional low-pressure casting equipment, such as grabbing and placing sand cores, sand suction, baking molds, graphite spraying and other processes, requires multiple people to cooperate with the casting machine to complete, it is difficult to realize automatic production, and the production efficiency is low
