Novel vibration type shakeout machine for sand mold casting

Abstract

The invention provides a novel sand casting vibration type shakeout machine which comprises a shell, a screen drum is arranged on the inner side of the shell, a plurality of springs are arranged between the screen drum and the shell, a first hydraulic air cylinder is arranged at one end of the inner side wall of the shell, the other end of the inner side wall of the shell is connected with a distance sensor, the bottom of the screen drum is connected with a first universal wheel, and the bottom of the first universal wheel is connected with a second universal wheel. The first universal wheels are in rolling connection with the bottom plate, the bottom plate is fixedly connected with the inner side wall of the shell, the two ends of the upper portion of the inner side of the shell are connected with fixing plates correspondingly, and the two ends of the top face of the screen drum are connected with second universal wheels correspondingly. According to the casting desanding device, the screen drum is arranged, the springs are arranged between the screen drum and the shell, the screen drum is driven to move through the elastic force of the springs, and therefore vibration desanding is conducted on a casting, the desanding efficiency is greatly improved, and the stability of the screen drum during moving is greatly improved through second universal wheels; and a closing assembly is arranged, so that the top of the screen drum is closed.

Description

technical field [0001] The invention belongs to the technical field of casting, and in particular relates to a novel vibration type shakeout machine for sand casting. Background technique [0002] Sand casting, a casting method for producing castings in sand. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting; the casting process requires smelting the metal into a liquid and then pouring it into a casting mold made of molding sand. After the mold is cooled to a certain temperature, in order to obtain the casting, the vibration generated by the shakeout machine is required to break the casting mold, so that the casting and the molding sand are separated. [0003] In the prior art, the shakeout efficiency of the shakeout machine is low, and the loss to the machine itself is relatively large; castings are often put in or moved manually, and the shakeout machine is often inefficient, thereby greatly increasing the production cost of the enterprise. ...
