Abstract

The invention discloses a casting mold for a multiple directional control valve. The casting mold for the multiple directional control valve comprises a sand box, outer shells and a mud core. The mudcore is horizontally arranged in the outer shells, and the outer shells are embedded in the sand box. A cavity for the multiple directional control valve is formed between the outer shells and the mudcore. The number of the outer shells is two, the outer shells refer to the outer shell I and the outer shell II, the outer shell I and the outer shell II are arranged in the sand box side by side, and the two corresponding outer side surfaces of the outer shell I and the outer shell II are attached to each other. The mud core comprises a main core and a plurality of small cores, the main core andthe multiple small cores are assembled into the whole mud core through auxiliary holes, a core rod for forming the multiple directional control valve is arranged in the whole mud core, an air outlethole is formed in the top of the whole mud core, and the air outlet hole is guided out through a steel wire. By means of the casting mold for the multiple directional control valve, assembling difficulty of the mud core can be solved, and the number of defects of castings can be reduced.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a casting mold for a multi-way reversing valve. Background technique [0002] The multi-way reversing valve is a combination of more than two valve blocks to manipulate the movement of multiple actuators. According to the requirements of different hydraulic systems, it can combine safety valves, overload valves, oil supplement valves, diverter valves, brake valves, check valves, etc., so it has compact structure, simple pipeline, small pressure loss, and It is easy to install, so it is widely used in construction machinery, hoisting and transportation machinery and other walking machinery that requires the manipulation of multiple actuators. [0003] The multi-way reversing valve designed by Changde Zoomlion Hydraulic Co., Ltd. has advanced design, small size, reliable action, multiple functions, long service life and can replace imported ones. It has the characteristics of high i...
