Formation post-processing machine for precise cast three-way valve

Abstract

The invention relates to a formation post-processing machine for a precise cast three-way valve. The formation post-processing machine comprises a working frame, an electric slider, a clamping device,a connecting rod, a push cylinder, an air charging device and a core removing device; the electric slider is installed at the left end of the working frame; the clamping device is arranged on the electric slider; the connecting rod is installed at the right end of the working frame; the push-out end of the connecting rod is connected with the core removing device by virtue of the push cylinder; and the air charging device is arranged between the core removing device and the connecting rod and is installed at the bottom end of the working frame. The formation post-processing machine provided by the invention can solve the problems that the internal space of the three-way valve is relatively small, the sight is relatively blurry, the inside of the three-way valve cannot be cleaned completely by manual sand removal, the inner wall of the three-way valve may be abraded when sand is removed by overuse of a cutter, the cutter is easily deformed after having direct collision with inner coresand when a person usually uses the cutter to randomly smash the inner core sand, and the high temperature generated by friction of the cutter and the inner core sand can easily cause overheating of the surface of the cutter and the like.

Description

technical field [0001] The invention relates to the field of three-way valve processing, in particular to a precision casting three-way valve post-processing processing machine. Background technique [0002] Precision casting refers to the general term for the process of obtaining precision-sized castings. The products processed by precision casting are precise, complex, and close to the final shape of the parts, and can be used directly without or with little processing. Precision casting includes sand cavity casting and ceramic casting. , metal mold casting, pressure casting, lost foam casting, commonly used three-way valves usually use sand cavity casting, three-way valves need shelling and sand cleaning after production, and the commonly used sand cleaning work usually manually cleans the inner wall of the three-way valve. This sand cleaning method often has the following defects: [0003] 1. Due to the small internal space of the three-way valve and the blurred vision,...

AI Technical Summary

Problems solved by technology

[0003] 1. Due to the small internal space of the three-way valve and the blurred vision, it is difficult to completely clean the inside of the three-way valve by manual sand cleaning. Excessive use of tools for sand cleaning may cause wear on the inner wall of the three-way valve;

[0004] 2. Personnel usually use knives to randomly crush the inner core sand. When the tool directly collides with the inner core sand, it is easy to cause the tool to deform, and the high temperature generated by the friction between the two is likely to cause the surface of the tool to overheat, thereby shortening its service life.
