Casting sand box turnover machine

Abstract

The invention relates to a casting sand box turnover machine. The casting sand box turnover machine comprises a rotary unit, a bearing unit, a chute unit and a limiting unit, wherein the rotary unit comprises brackets on both sides and a rotary shaft which is rotatably arranged between the brackets on the both sides; the bearing unit is arranged on the lower part of the rotary unit, and the bearing unit comprises lower clamping seats on both sides, a connecting plate which is used for connecting the clamping seat on the both sides and a support frame which is arranged below the connecting plate; the chute unit is arranged on the upper part of the rotary shaft, the chute unit comprises upper clamping seats on both sides and a chute which is connected with the upper clamping seats on the both sides, and the upper clamping seats and the lower clamping seats are buckled on the rotary shaft; and the limiting unit is rotatably arranged in the chute, the limiting unit comprises a limiting frame and a grate plate which is arranged in the limiting frame, a plurality of connecting rods are arranged between the limiting frame and the support frame, and a dust hood is arranged on the upper part of the limiting frame. The casting sand box turnover machine has the advantage of the reasonable structure, casting sand and castings can be preferably separated once, the diffusion of flying dust can be avoided, and the clean operating environment is guaranteed.

Description

technical field [0001] The invention relates to the technical field of V-method casting, in particular to a casting sand box turning machine. Background technique [0002] V-method casting uses plastic film to seal the sand box, and the air in the mold is drawn out by the vacuum pumping system. There is a pressure difference between the inside and outside of the mold, which makes the dry sand dense and forms the required cavity. The casting is solidified, the negative pressure is released, and the molding sand collapses to obtain the casting. [0003] After the required castings are obtained, the sand box needs to be placed on the box turning machine. The worker is in the sand shakeout position and operates the box turner to turn the box and dump the sand to take out the model and castings. As far as the sand shakeout position is concerned, the safety factor is low. When pouring the sand, the flying dust is so diffuse that the working environment is poor and the pollution i...

Problems solved by technology

[0005] In order to solve the problem that the traditional sand pouring has a lot of dust and cannot separate the molding sand from the casting well, the present invention provides a foundry sand box turning machine, which can ensure good fixing of the sand box and clean working environment, and realizes one-time separation of molding sand. and castings
