Casting machinery sand mixing device with good sand discharge effect

Abstract

The invention discloses a casting machinery sand mixing device with the good sand discharge effect and specifically relates to the technical field of casting machinery. The casting machinery sand mixing device with the good sand discharge effect comprises a box. A grinding mechanism is fixedly mounted on the top of the box. A dust removal mechanism is connected to the other side of the top of thebox. An inner shell is fixedly connected to an inner cavity of the box. A screening mechanism is arranged at the bottom of the inner shell. One side of the inner shell is connected with a feed hopper.The bottom of the inner shell is connected with an inner discharge pipe. The bottom of the inner discharge pipe is connected with an electric gate plate. The lower portion of the inner cavity of thebox is fixedly connected with a sand mixing box. The bottom of the sand mixing box is provided with a second motor. Through arrangement of a grinding block and a screen plate, the casting machinery sand mixing device can effectively screen out big particles in a sand mold raw material. Stirring rods rotate to mix the sand mold material. The mixing fineness of the sand mold raw material is effectively improved through grinding and screening of the sand mold raw material. Compared with the prior art, the casting machinery sand mixing device with the good sand discharge effect has the advantagesof remarkably increasing the rate of finished products of the casting machinery and meeting the use requirements.

Description

technical field [0001] The invention relates to the technical field of foundry machinery, and more specifically, the invention relates to a sand mixing device for a foundry machine with good sand production effect. Background technique [0002] Casting is one of the basic processes of modern machinery manufacturing industry. As a metal thermal processing technology, casting has gradually matured in my country. Foundry machinery is to use this technology to smelt metal into a liquid that meets certain requirements and pour it into the mold. After cooling, solidification, and cleaning, all the mechanical equipment that can be used to obtain castings with predetermined shape, size and performance, Also known as casting equipment. [0003] In the manufacture of casting molds, it is often necessary to use a sand mixing device to mix the sand to achieve the required hardness. The existing sand mixing device lacks the ability to screen the molding sand material, which leads to t...
