Sand turning device for casting piece processing

Abstract

The invention belongs to the technical field of casting, and particularly relates to a sand turning device for casting part processing. The sand turning device comprises a stirring barrel and a stirring motor fixed at the bottom end of the stirring barrel, wherein the stirring motor is electrically connected with an external power supply, the output end of the stirring motor is fixedly connected with a stirring paddle, the stirring paddle is positioned inside the stirring barrel, a discharging mechanism is further mounted at the bottom end of the stirring barrel, and a screening mechanism is further installed at the top end of the inner portion of the stirring barrel. According to the sand turning device, the required fine sand is firstly put through a feeding hopper and screened through ascreening mechanism, and the fine sand falls into the stirring barrel for stirring and mixing. While the fine sand is stirred and mixed, the fine sand can be screened and filtered, impurities in thefine sand are removed, the fine sand does not need to be screened and filtered separately, the transferring times of the fine sand is reduced, the production efficiency is improved, the labor intensity of personnel is relieved, the occupied area of the equipment can be reduced at the same time, and the space utilization rate in the factory is improved.

Description

technical field [0001] The invention belongs to the technical field of casting, and in particular relates to a foundry device for processing castings. Background technique [0002] Casting is to melt a metal into a liquid, and then inject hydraulic pressure into the mold to obtain a casting. Because the metal has a strong adhesiveness after hydraulic cooling and solidification, only fine sand is used to make casting molds, but fine sand is made into casting molds. It is necessary to add a certain amount of bonding colloid to the fine sand, and mix the fine sand with the bonding colloid evenly. Since the fine sand needs to be used repeatedly, in the process of recycling and transporting, there will be impurities in the fine sand. Before the sand is mixed and stirred, the fine sand needs to be screened and filtered to remove impurities in the fine sand. [0003] The existing sand foundry device can only stir and mix the fine sand, and it is necessary to screen and filter the ...

AI Technical Summary

Problems solved by technology

[0003] The existing sand foundry device can only stir and mix the fine sand, and it is necessary to screen and filter the fine sand separately, and then put the fine sand into the sand foundry device for stirring and mixing, which increases the number of transfers of the fine sand, and the production efficiency of the fine sand cannot be achieved. Further improvement, at the same time, the separate screening equipment occupies a limited space in the factory, and the space utilization rate is low
