Description

Technical Field

[0001] The utility model relates to the technical field of loader hydraulic valve body production, in particular to a loader hydraulic valve body casting mold. Background Art

[0002] The loader hydraulic valve body is an automatic component operated by pressure oil. It is controlled by the pressure oil of the pressure regulating valve. It is usually used in combination with the electromagnetic pressure regulating valve and can be used to remotely control the on and off of the oil, gas and water pipeline systems of the hydropower station. It is often used for clamping, control, lubrication and other oil circuits. There are direct-acting type and pilot type, and the pilot type is mostly used. When processing the loader hydraulic valve body, it needs to be processed through a casting mold.

[0003] During the processing of the existing loader hydraulic valve body casting mold, the required casting temperature is about 1520 degrees. After the finished product is taken out, the remaining debris on the mold needs to be cleaned by an air gun and cloth. However, the cavity of the molding block has a certain curvature. When blowing air through the air gun, it is easy to cause the blown-out residue to fall into the interior of the cavity again through wind force and gravity, which has low practicality.
