Problems solved by technology

During the production process of the shell core machine, sand will fall into the mold when the sand cylinder advances in place, and the falling sand will solidify quickly in the mold, resulting in unqualified product surface
At present, the shell core machines on the market do not have a very effective solution to the problem of sand falling out of the sand drum. This invention provides an effective method to solve this problem.

Abstract

The invention provides an anti-shakeout method for a shell core machine. The shell core machine is characterized by consisting of a hydraulic buffer, a buffer rod, a sand ejecting cylinder rail, rail wheels and a sand ejecting cylinder bracket, wherein the rail wheels are mounted at the upper part of the sand ejecting cylinder bracket, and are arranged in the sand ejecting cylinder rail; and the buffer is mounted on the sand ejecting cylinder bracket. With the adoption of a buffering device combining the hydraulic buffer with the buffer rod, the simplicity and the convenience can be realized; the shakeout problem of a sand ejecting cylinder in a sand ejecting process can be effectively solved; and the product quality and the working efficiency can be improved.

Description

technical field [0001] The invention relates to a method for preventing falling sand of a shell core machine, which is applied in the field of aluminum alloy casting, especially the casting of a compressor shell of a turbocharger. Background technique [0002] In the automotive turbocharger manufacturing industry, the cores used in casting superchargers are all produced by shell core machines. During the production process of the shell core machine, sand will fall into the mold when the sand cylinder advances in place, and the falling sand will solidify quickly in the mold, resulting in unqualified product surface. At present, the shell core machines on the market do not have a very effective solution to the problem of sand shakeout from the sand drum. The present invention provides an effective method to solve this problem. Contents of the invention [0003] A method for preventing sand falling of a shell core machine, which is characterized in that it is composed of a h...
