Description

Technical Field

[0001] This utility model belongs to the field of casting production, and in particular relates to a tool that facilitates the turning and cleaning of casting molds. Background Technology

[0002] In the casting process, sand casting is one of the most widely used casting methods. It involves placing casting sand and a wooden mold into a sand box and compacting them to form a mold for later use. After each casting is produced, the mold needs to be cleaned and dried using air guns and heat treatment before reuse. During cleaning and drying, the mold needs to be lifted, tilted, or even inverted to remove any residual waste material. To prevent waste material from sticking to the mold after it has completely cooled, and to increase production efficiency, workers need to clean the mold while it is still warm. In existing technologies, the mold flipping process still requires workers to maintain a close distance to the mold, which can easily lead to burns. Utility Model Content

[0007] The control unit includes a handwheel and a second limiting ring coaxially arranged with the handwheel. The first limiting wheel and the second limiting wheel are fixedly connected by a connecting handle. The handwheel rotates synchronously with the second transmission wheel, and the first transmission wheel and the second transmission wheel are connected by transmission.

[0008] Furthermore, the inner wall of the first limiting ring and / or the second limiting ring has a circumferential groove, and the connecting part extends outward to form a retaining edge, which is placed inside the circumferential groove.

[0009] Furthermore, the first limiting ring and / or the second limiting ring include a ring cover and an L-shaped ring body, and the ring groove is formed by the ring body and the ring cover surrounding it.

[0010] Furthermore, the connecting portion extends outward from the first limiting ring to form a first synchronous shaft, and the first transmission wheel is connected to the first synchronous shaft.

[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] In this embodiment of the tool for facilitating the turning and cleaning of casting sand boxes, the sand box 4 has columnar lifting lugs extending outward from both sides. A crane or other lifting device is connected to the lifting lugs via wire ropes or straps to lift the sand box 4. A torque plate is welded to the end of at least one lifting lug, allowing the sand box 4 to rotate around the axis of the lifting lug. To prevent the wire rope from slipping off the lifting lug during lifting, protective edges 42 extend radially outward from both ends of each lifting lug 41.

[0033] The cleaning tool includes a working part 2 and a control part 3, connected by a connecting handle 1. The position of the working part 2 can be adjusted via the connecting handle 1. The working part 2 includes a connecting part 21 that can drive the sand box 4 to rotate around a rotation axis, and a first transmission wheel 22 that rotates synchronously with the connecting part 21. The connecting part 21 is detachably connected to the sand box 4. In this embodiment, the connecting part 21 is disc-shaped with a insertion hole 211 on its axis. The torque plate can be inserted into the insertion hole 211, and when the connecting part 21 rotates around its own axis, the torque plate can drive the sand box 4 to rotate synchronously. The edge of the insertion hole 211 is chamfered. In other embodiments, the lifting lug of the sand box 4 can also have a torque hole, and the connecting part 21 extends outward to form a plug that mates with the torque hole for detachable insertion. The connecting part 21 is provided with a first limiting ring 23. In this embodiment, the first limiting ring 23 includes a ring body 231 and a ring cover 232. The cross-section of the ring body 231 is shaped like a ring. The ring cover 232 can be connected to the edge of the ring body 231 by screwing, snap-fitting, or embedding, so that the ring cover 232 is fixed on the ring body 231. The ring cover 232 and the ring body 231 surround and form an annular groove on the inner side of the limiting ring. The edge of the connecting part 21 extends radially outward to form a retaining edge 213. The retaining edge 213 is placed in the annular groove and limits the connecting part 21 to prevent the connecting part 21 from separating from the first limiting ring 23. The first synchronous shaft 212 extends outward from the first limiting ring 23. The first transmission wheel 22 is connected to the first synchronous shaft 212. In this embodiment, the first synchronous shaft 212 and the first transmission wheel 22 are connected by a key. Optionally, the two can also be fixedly connected by a set screw passing through the first transmission wheel 22, so that the first transmission wheel 22 and the connecting part 21 rotate coaxially and synchronously. When the connection method is key connection, the first synchronous shaft is provided with a clearance gap 2121. The edge of the L-shaped ring 231 can pass through the clearance gap 2121, and a clearance slot 2311 is opened on the inner side of the ring. The key on the first synchronous shaft can pass through the clearance slot 2311 for easy installation and use.

[0034] The control unit 3 includes a handwheel 31 and a second limiting ring 33 coaxially arranged with the handwheel 31. The handwheel 31 rotates synchronously with the second transmission wheel 32. In this embodiment, the second limiting ring 33 has the same structure as the first limiting ring 23. A second synchronous shaft 311 extends outward from the middle of the handwheel 31. The second synchronous shaft 311 is coaxially connected to a second transmission wheel 32. Similarly, in this embodiment, the second transmission wheel 32 and the second synchronous shaft 311 can be connected by a key or a set screw. The first transmission wheel 22 and the second transmission wheel 32 are connected by transmission. In this embodiment, the first transmission wheel 22 and the second transmission wheel 32 are sprockets, and they are connected by transmission through a chain 5. Optionally, the first transmission wheel 22 and the second transmission wheel 32 can also be pulleys or synchronous pulleys, and they can be connected by transmission through belts or synchronous belts or other transmission methods. The two ends of the connecting handle 1 are respectively fixed to the ring body 231 of the first connecting ring and the second connecting ring.

[0035] The tool described in this utility model facilitates gradual sand box rotation and cleaning. During use, the position of the working part 2 and the angle of the insertion hole 211 of the connecting part 21 are controlled by the connecting handle 1 and the handwheel 31. The torque plate is inserted into the insertion hole 211, and the sand box 4 is rotated by rotating the handwheel 31, thereby changing the posture of the sand box 4 until it is adjusted to a predetermined angle. The mold inside the sand box 4 is then cleaned by blowing with an air gun.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
