Casting sand removing device

Abstract

The invention belongs to the field of casting equipment, and particularly discloses a casting sand removing device. The casting sand removing device comprises a sand removing box; a horizontal first movable plate and a horizontal second movable plate are sequentially arranged in the sand removing box from top to bottom in a sliding manner; the first movable plate and the second movable plate are both inclined; the first movable plate and the second movable plate are inclined in opposite directions; sand through holes are formed in the first movable plate and the second movable plate; a first push rod is vertically connected between the first movable plate and the second movable plate in a sliding manner; the top end of the first push rod is propped against the first movable plate; the bottom end of the first push rod is propped against the second movable plate; a first passage is arranged at the low end of the first movable plate; a second passage is rotationally connected with the inner side wall of the sand removing box below the first passage; spiral bulges are arranged on the inner wall of the first passage and the inner wall of the second passage; bristles are densely distributed on the bulges; a receiving slot is arranged between the first passage and the second passage; and a second push rod is connected with the receiving slot in a sliding manner. The device can turn over automatically when used for sand removal of castings.

Description

technical field [0001] The invention relates to the field of casting equipment, in particular to a casting sand removal device. Background technique [0002] Sand cleaning of castings is a very important process in the casting process. At present, the work of sand cleaning is generally carried out by manual sand cleaning. However, sand cleaning is a job with high labor intensity and harsh working environment in the casting industry, which will have a great impact on the health and safety of workers in the process of sand cleaning. Moreover, the cleaning speed of castings in this way is relatively slow, the processing efficiency is very low, and the cost of cleaning is relatively high. [0003] At present, there are also some sand cleaning machines for sand cleaning. However, the existing sand cleaning machines still need to manually put the castings in place during the sand cleaning process. In order to remove sand more thoroughly, the castings often need to be manually tu...

Problems solved by technology

However, sand cleaning is a job with high labor intensity and harsh working environment in the casting industry, which will have a great impact on the health and safety of workers during the process of sand cleaning

Moreover, the cleaning speed of castings in this way is slow, the processing efficiency is very low, and the cost of cleaning is relatively high

[0003] At present, there are also some sand cleaning machines for sand cleaning. However, the existing sand cleaning machines still need to manually put the castings in place during the sand cleaning process. In order to remove sand more thoroughly, it is often necessary to manually turn the castings

Although this method reduces the labor load of manual cleaning, it still requires manual operation during the process of placing and turning the casting, and manual operation is prone to fatigue, which ultimately leads to low sand cleaning efficiency.
