Abstract

The invention relates to the technical field of casting and particularly relates to a hydraulic steering gear shell casting mold. The hydraulic steering gear shell casting mold comprises a base, a movable mold and a fixed mold; a portal frame is fixedly mounted on the upper surface of the base; a moving assembly used for fixing the movable mold is arranged in the portal frame; a driving assembly is arranged on the portal frame; and the driving assembly is used for driving the moving assembly to move up and down. According to the hydraulic steering gear shell casting mold, the driving assembly is matched with the moving assembly to achieve precise closing between the movable mold and the fixed mold; the casting precision is improved; meanwhile, a rapid mold withdrawing function is achieved through a mold withdrawing assembly; the casting efficiency is improved while manpower consumption is reduced; an electromagnet is matched with a magnet block, and and handle bolts are matched with T-shaped inserting blocks and the T-shaped inserting grooves, so that the fixed mold and the movable mold are quickly disassembled and assembled; and the fixed mold and the movable mold can be quickly replaced when casting parts with different sizes are cast. The invention further relates to a method for casting shells by using the hydraulic steering gear shell casting mold.

Description

technical field [0001] The invention relates to the field of casting technology, in particular to a casting mold for a casing of a hydraulic steering gear, and in particular to a method for casting a casing by using the casting mold for a casing of a hydraulic steering gear. Background technique [0002] The hydraulic steering machine, namely the hydraulic power steering machine, is a set of gear mechanisms that complete the transformation from rotary motion to linear motion (or approximate linear motion). It is also the reduction gear in the steering system. It is the most important part of the steering system. The hydraulic steering machine is a cycloidal valve type full hydraulic steering machine composed of a follow-up rotary valve and a pair of cycloidal rotor stators. It is connected with the oil supply pump, overflow valve (or diverter valve), steering cylinder and other The accessories make up the full hydraulic steering system. [0003] The hydraulic steering gear ...
