High-pressure heating sand mold casting device

Abstract

The invention discloses a high-pressure heating sand mold casting device, and belongs to the technical field of sand mold casting. The device comprises a fixed plate, vertical rods, a high-pressure heating assembly and four clamping fixing assemblies, wherein four supporting rods are fixed to the bottom of the fixed plate, the vertical rods are fixed to the upper end of the fixed plate and are symmetrically arranged relative to the middle of the fixed plate, a lifting assembly is slidably connected into each vertical rod, the high-pressure heating assembly is fixed between the two lifting assemblies, and the four clamping fixing assemblies are fixed to the upper end of the fixed plate and located at the four corners of the fixed plate respectively. According to the device, motors drive screws to rotate, a fixing frame can be controlled to be adjusted up and down, and when a sand mold needs to be replaced for heating, the sand mold is convenient to dismount and mount; and meanwhile, thevalue of internal air pressure can be controlled to be the optimal value through pressurizing valves, the optimal pressure value of sand mold heating is ensured, and the mold manufacturing quality isimproved.

Description

technical field [0001] The invention belongs to the technical field of sand casting, in particular to a high-pressure heating sand casting device. Background technique [0002] Sand casting refers to the casting method of producing castings in sand molds. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting methods. Because the molding materials used in sand casting are cheap and easy to obtain, the casting molds are easy to manufacture. It can be adapted to piece production, batch production and mass production. It has been the basic process in casting production for a long time. [0003] However, in the existing sand casting device, the temperature and pressure cannot be raised during the casting process, so that when casting some special metal materials, the casting requirements cannot be met, the performance of the casting product is not perfect, and the casting mold cannot be replaced. When people need When replacing castings, the entire ca...

[0003] However, in the existing sand casting device, the temperature and pressure cannot be raised during the casting process, so that when casting some special metal materials, the casting requirements cannot be met, the performance of the casting product is not perfect, and the casting mold cannot be replaced. When people need When replacing castings, the entire caster has to be replaced, wasting the caster, etc.
