Technical Field
[0001] The utility model relates to the technical field of mold cleaning, in particular to a novel cleaning device for sand casting molds. Background Art
[0002] Sand casting refers to a casting method that produces castings in sand molds. It changes the shape of the metal molding by changing the shape of the sand accumulation inside the casting mold. Therefore, when the metal casting is completed, some of the sand inside the casting mold will adhere to the inner wall of the casting mold due to extrusion. At this time, the sand on the inner wall needs to be cleaned by a cleaning device. The most common method is to use the gas generated by an air pump to impact the inner wall of the mold to achieve the cleaning effect.
[0003] The existing air pump will generate a lot of sand and dust when cleaning the sand on the inner wall of the mold, which leads to a poor working environment and operators are prone to inhale a large amount of sand and dust, which is not good for their health. Utility Model Content

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0018] Reference Figure 1-Figure 5 As shown, a novel cleaning device for sand casting molds comprises an air pump 1, an air jet pipe 2 is fixedly installed at the air outlet interface of the air pump 1, a mounting port is horizontally penetrated through the surface of the air jet pipe 2, a rotating shaft 3 is horizontally sealed and rotatably installed in the mounting port, a rotating plate 4 is fixedly sleeved on the rotating shaft 3, the rotating shaft 3 is connected to the air jet pipe 2 through an elastic component, the elastic component comprises two torsion springs 11 symmetrically sleeved on the rotating shaft 3, mounting blocks are fixedly installed at both ends of the rotating shaft 3, the two ends of the torsion spring 11 are respectively fixedly connected to the mounting block and the air jet pipe 2, an air outlet bag 8 is fixedly installed at the bottom end of the air jet pipe 2; a mounting plate is fixedly installed on the surface of the air jet pipe 2, a water storage tank 5 is fixedly installed on the upper surface of the mounting plate, An arc-shaped hollow rod 6 connected to the water tank 5 is fixedly mounted on the lower surface of the mounting plate, a through hole is opened on the surface of the jet pipe 2, an arc-shaped piston rod 7 is fixedly mounted on the lower surface of the rotating plate 4, the end of the piston rod 7 away from the rotating plate 4 passes through the through hole and is sealed and slidably inserted in the hollow rod 6, an outlet pipe 9 is fixedly mounted on the surface of the hollow rod 6, a nozzle 10 is fixedly mounted on one end of the outlet pipe 9, and the nozzle 10 corresponds to the position of the air outlet tube 8, a one-way valve is arranged in the top end of the hollow rod 6 and in the outlet pipe 9, the conducting direction of the one-way valve in the top end of the hollow rod 6 is from the water tank 5 to the hollow rod 6, and the conducting direction of the one-way valve in the outlet pipe 9 is from the hollow rod 6 to the nozzle 10.
[0019] In the initial state, that is, when the air pump 1 is not working, the rotating plate 4 will be in a horizontal state in the jet pipe 2 under the elastic potential energy of the torsion spring 11. When the air pump 1 is working and the gas passes through the jet pipe 2, the rotating plate 4 will rotate under the push of the gas. During the rotation, the piston rod 7 will move in the hollow rod 6, the volume in the hollow rod 6 will decrease, and the pressure will increase. The water in the hollow rod 6 will enter the nozzle 10 from the water outlet pipe 9, be sprayed out in the form of mist and act on the air outlet 8, which can play a certain dust suppression effect and avoid dust in the cleaning process. In the process, more sand and dust are generated, which affects the working environment and the health of the operators, and the spraying of water mist does not require an additional electric drive device, which reduces the electricity cost; then when the gas is no longer introduced into the jet pipe 2, the rotating plate 4 will quickly rotate and reset under the elastic potential energy of the torsion spring 11, and the piston rod 7 will move in the hollow rod 6. The volume in the hollow rod 6 becomes larger, while the pressure decreases, and the water in the water tank 5 will enter the hollow rod 6. When the gas is introduced into the jet pipe 2 next time, the water in the hollow rod 6 will be sprayed out from the nozzle 10 in the form of mist.
[0020] The water tank 5 is made of transparent material and has a scale on its surface. The transparent water tank 5 allows the operator to know the water level in the water tank 5 in a timely manner. When the water is less, water can be added quickly to a suitable level according to the scale.

[0022] In the initial state, that is, when the air pump 1 is not working, the rotating plate 4 will be in a horizontal state in the jet pipe 2 under the elastic potential energy of the elastic component. When the air pump 1 is working and the gas passes through the jet pipe 2, the rotating plate 4 will rotate under the push of the gas. During the rotation, the piston rod 7 will move in the hollow rod 6, the volume in the hollow rod 6 will decrease, and the pressure will increase. The water in the hollow rod 6 will enter the nozzle 10 from the water outlet pipe 9, be sprayed out in the form of mist and act on the air outlet 8, which can play a certain dust suppression effect and avoid dust in the cleaning process. In the process, more sand and dust are generated, which affects the working environment and the health of the operators, and the spraying of water mist does not require an additional electric drive device, which reduces the electricity cost. Then, when the gas is no longer introduced into the jet pipe 2, the rotating plate 4 will quickly rotate and reset under the elastic potential energy of the elastic component, and the piston rod 7 will move in the hollow rod 6. The volume in the hollow rod 6 becomes larger, and the pressure decreases. The water in the water tank 5 will enter the hollow rod 6. When the gas is introduced into the jet pipe 2 next time, the water in the hollow rod 6 will be sprayed out from the nozzle 10 in the form of mist.
