Description

Technical Field

[0001] This utility model relates to the field of counterweight casting, and in particular to a sand box turning device for counterweight casting. Background Technology

[0002] Counterweights are used to increase their own weight to maintain balance. Counterweights require V-process casting sand boxes during production. V-process casting is a green and environmentally friendly casting method. The advantages of using V-process casting are that the molding sand does not use binders, the sand removal is simple, the amount of molding sand is reduced to a minimum, and most sand particles can be reused, saving costs. Generally, V-process casting requires the use of machinery to turn the sand box over.

[0003] A search of Chinese patents revealed publication number CN221473452U, which discloses a sand box turning device for casting. The device includes a water platform, a motor on one side of the upper surface of the water platform, and a turning mechanism on the other side. A sand box fixing box is located between the turning mechanism and the motor. The sand box fixing box has a placement groove inside, and a sand box is placed inside the placement groove. A support structure is fitted around the sand box fixing box. Two locking blocks are located inside each side of the support structure, and each locking block has a slot. A limiting groove is located inside the support structure, and a fixing block is located inside the limiting groove. A pull rod, which penetrates the support structure, is fixed to the upper surface of the fixing block. A spring A is fitted around the pull rod and located inside the limiting groove. A spring B is located inside the fixing block and located inside the spring groove. This invention improves the efficiency of subsequent turning by strengthening the fixation of the sand box.

[0004] Existing sand box turning devices have limited applicability. Generally, the spacing between the fixing heads of sand box turning devices is fixed, and they can only be used for sand boxes of a fixed size. If it is necessary to turn sand boxes of different sizes, the turning device needs to be replaced, which increases the cost of use, reduces practicality, and is also inconvenient for installing and disassembling sand boxes. Generally, the sand box is fixed to the fixing head with multiple bolts, and tools are needed for installation and disassembly, which is cumbersome, increases workload, and reduces work efficiency. In order to solve the above problems, we propose a sand box turning device for counterweight block casting. Utility Model Content

[0005] The purpose of this utility model is to provide a sand box flipping device for counterweight casting, which has the advantages of high applicability and inconvenience in assembling and disassembling the sand box.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a sand box turning device for casting counterweight blocks, comprising a fixed frame, a lifting mechanism provided on the top of the fixed frame, two sliding grooves opened on the surface of the fixed frame, sliders slidably connected to the inner walls of the sliding grooves, a lifting rod bolted between the two sliders, two sliding grooves opened on the inner wall of the lifting rod, sliding blocks slidably sleeved on the inner walls of the sliding grooves, a double-acting screw threadedly connected to the inner wall of the sliding block, the double-acting screw rotatably sleeved with the inner wall of the lifting rod, and the double-acting screw rotatably sleeved with the inner wall of the left slider, a transmission block bolted to the surface of the sliding block, the transmission block slidably connected to the inner wall of the lifting rod, and a sliding cylinder bolted to the surface of the transmission block, the sliding cylinder slidably sleeved with the surface of the lifting rod.
