A sand-shocking process after casting molds for three-way valves

Abstract

The invention provides a three-way valve casting sand shakeout process, which comprises a fixed base, a support plate, a fixed locking mechanism, a vertical sand shakeout mechanism and a horizontal sand shakeout mechanism. The present invention solves the need to manually use a rubber hammer or an inverted sand pestle to perform shakeout treatment on sand castings after the existing sand castings have been removed from the mold. Manual shakeout has low production efficiency, much dust and long working hours, and the traditional method The shakeout tool is difficult to handle valve pipes with different diameters and pipes in different directions at the same time. The design of the invention improves the working efficiency of the shakeout operation, and has a wide range of applications and a strong shakeout effect. and high work efficiency.

Description

technical field [0001] The invention relates to the technical field of sand shakeout of castings, in particular to a sand shakeout process after casting a three-way valve casting mold. Background technique [0002] Shaking of castings refers to the operation process of separating castings from molding sand and sand boxes by hand or machinery. The general term for the process of removing surface sticky sand, molding sand, excess metal, etc. from castings after sand falling is called casting cleaning. The production of three-way valves by sand casting is relatively common in actual production. After the three-way valve is cast, the workpiece is taken out, and the sand is removed from the inside of the workpiece after fixing the workpiece. This is a commonly used process. [0003] However, the following problems exist in the shakeout treatment of existing sand castings after mold removal. 1. Traditional shakeout operations generally use rubber hammers or sand-inverting pestles...

Problems solved by technology

[0003] However, the following problems exist in the shakeout treatment of existing sand castings after mold removal. 1. Traditional shakeout operations generally use rubber hammers or sand-inverting pestles to perform shakeout treatment on sand castings, and the production efficiency of manual shakeout is low. , a lot of dust, high temperature, poor working conditions, and long working hours, which are easy to cause physical injury to the staff. Second, sand castings need to be continuously turned over during work, resulting in the inability to collect the casting sand
