Problems solved by technology
[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: when the air compressor injects the filtrate in the holding furnace into the mold cavity, due to the large volume of the inner cavity of the holding furnace, the air compressor needs to pass into the holding furnace. A large amount of compressed gas makes the air compressor load larger, thereby reducing the service life of the air compressor, and the low-pressure casting machine needs to be shut down when maintaining or replacing the air compressor, thereby reducing the production efficiency of the low-pressure casting machine

The application relates to a low-pressure casting machine, a low-pressure casting machine, comprising a frame, a holding furnace and an air compressor are arranged on the frame, a liquid riser is arranged in the holding furnace, an adjusting mechanism is arranged in the holding furnace, and the adjusting mechanism It includes a pressure cylinder block and a one-way assembly. The pressure cylinder block is installed in the holding furnace and forms a sealed cavity with the holding furnace. The riser pipe penetrates into the sealed cavity, and the one-way assembly is installed on the pressure cylinder block and makes the liquid one-way. Flow into the sealing cavity, and the air compressor communicates with the interior of the sealing cavity. The application has the advantages of reducing the load of the air compressor, thereby increasing the service life of the air compressor; at the same time, the service life of the castings; and increasing the service life of the pressure cylinder, reducing the time of the low-pressure casting machine downtime for maintenance, thereby improving the low-pressure casting machine. The effect of production efficiency.
Description
technical field [0001] The present application relates to the technical field of low pressure casting machines, in particular to a low pressure casting machine. Background technique [0002] Low pressure casting machine is a general equipment for low pressure casting of aluminum alloy, which can be widely used in the production of aluminum alloy castings in automobiles, motorcycles, instruments, textile machinery and aerospace industries. [0003] In the related art, a low-pressure casting machine includes a frame, and the frame is slidably provided with a mold, a hydraulic system connected to the mold, a molten pool type holding furnace and an air compressor under the mold, and the like. The holding furnace is fixedly provided with a The riser pipe connected to the mold cavity; when casting aluminum alloy castings, the air compressor feeds compressed gas into the holding furnace, and the pressure of the gas acts on the liquid level of the aluminum water, so that the aluminu...
