Sand mixing device with good sand discharging effect for casting machinery

Abstract

The invention discloses a sand mixing device with good sand discharging effect for a casting machinery. The sand mixing device with the good sand discharging effect for the casting machinery comprisesa base and a material shaking device, a supporting column is fixedly connected to the outer wall of the top of the base, a fixing plate is fixedly connected to the end, away from the base, of the supporting column, an outer shell is fixedly connected to the outer wall of the top of the fixing plate, a mixing box is fixedly connected to the outer wall of the top of the fixing plate and located inthe interior of the outer shell, a first mounting plate is fixedly connected to the outer wall of the top of the outer shell, a first motor is fixedly connected to the outer wall of the top of the first mounting plate, a rotating shaft is fixedly connected to an output shaft of the first motor, the outer wall of one side of the rotating shaft is fixedly connected with a connecting rod, and one end, away from the rotating shaft, of the connecting rod is rotationally connected with a grinding roller. By means of up-and-down rotating motion of molding sand, the molding sand is mixed more sufficiently, the mixing efficiency is higher, the working efficiency is improved to a certain extent, and compared with the prior art, the sand mixing efficiency of a casting machine is remarkably improved,and the use requirement is met.

Description

technical field [0001] The invention belongs to the technical field of foundry machinery, and in particular relates to a sand mixing device with good sand output effect for foundry machinery. 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. 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. In the process of mixing molding sand in the traditional sand mixer, the molding sand often accumulates on the inner wall of the sand m...

Problems solved by technology

[0005] The object of the present invention is to provide a kind of sand mixing device with good sand producing effect for foundry machinery, to solve the problem of the existing sand mixing device with good sand producing effect for foundry machinery proposed in the above background technology. When the advanced sand mixing device is in use, the molding sand is prone to stick to the inside of the sand mixer, the mixed molding sand cannot be completely discharged, and the mixing efficiency is low, which leads to the problems of inconvenient unloading of molding sand, waste of molding sand and low mixing efficiency
