Description

Technical Field

[0001] This utility model relates to the field of casting production, and in particular to a device for cleaning iron pellets from the surface of a box. Background Technology

[0002] In the casting industry, hydrostatic molding production lines are key equipment for achieving automated and efficient sand casting production, widely used in the mass production of metal castings such as automotive parts and engineering machinery components. One of the core steps of this production line is molten metal pouring, where high-temperature molten metal is introduced into the sand mold cavity through a gating system, and the casting is formed after the molten metal cools and solidifies. During the pouring process, due to factors such as the impact of the molten metal flow and poor venting of the sand mold cavity, some molten metal splashes. These splashed droplets, upon contact with air and the surface of the low-temperature sand box, rapidly cool and solidify, forming iron pellets (or "iron filings" or "small iron pieces") of varying diameters, which adhere to the surface of the sand box. For hydrostatic molding production lines, the resulting splashed iron pellets and small iron pieces, if not properly cleaned, can enter the equipment, causing anything from minor equipment malfunctions and shutdowns to severe equipment damage, ultimately impacting production efficiency.

[0003] Currently, cleaning iron pellets from the surface of sand boxes mainly relies on manual operation. After the sand box is transported to the designated workstation by the production line, the operator uses a tool to manually scrape the surface of the sand box and collect the iron pellets into a container. This is not only inefficient, but also increases the workload and cleaning cost. Furthermore, the sand box may still retain a certain temperature after cooling, posing a risk of burns when operating manually at close range. In addition, the sharp edges of the iron pellets can easily cut the operator, posing a certain safety hazard. In order to solve the above problems, we propose a device for cleaning iron pellets from the surface of the sand box. Utility Model Content

[0004] The purpose of this invention is to provide a device for cleaning iron pellets on the surface of a box, which has the advantage of high cleaning efficiency.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a box surface iron bean cleaning device, including a fixed frame, two rotating shafts rotatably sleeved between the inner walls of the fixed frame, sprockets fixedly sleeved on the surface of the rotating shafts, a chain drivingly connected between the surfaces of the sprockets, a slide block bolted between the two ends of the chain, a moving mechanism provided between the slide block and the inner wall of the fixed frame, a motor bolted to one end of the rotating shaft on the right side, and the motor bolted to the surface of the fixed frame, a hydraulic lifting rod bolted to the top of the slide block, a lifting plate bolted to the bottom of the hydraulic lifting rod, an electromagnetic chuck provided at the bottom of the lifting plate, and a collecting mechanism provided at the bottom of the fixed frame.

[0006] Using the above technical solution, the electromagnetic chuck is lowered by the hydraulic lifting rod and brought close to the surface of the sand box. The electromagnetic chuck is then energized and magnetized, which can pick up the iron beans and iron blocks on the surface of the sand box. The electromagnetic chuck is then raised and moved to the slag collection bucket. The power is turned off and the magnetization is demagnetized, which can release the adsorbed iron beans. Then it returns to the adsorption station. The adsorption efficiency is high, unnecessary downtime is avoided, production efficiency is greatly improved, and labor is also saved.

[0007] The present invention is further configured such that: the moving mechanism includes a slide rail, the top and bottom of the slide rail are tumblingly connected to first rollers, and the first rollers are bolted to the surface of the slide block; the two sides of the slide block are bolted to second rollers, and the second rollers are tumblingly connected to the surface of the slide rail.

[0008] By adopting the above technical solution, a moving mechanism is set up, and the first and second rollers limit the slide block. By reducing friction with the slide rail, energy consumption is reduced and stability is improved.

[0009] The present invention is further configured such that: the collecting mechanism includes a collecting hopper, the collecting hopper is located at the bottom of the fixed frame, a trolley is provided at the bottom of the collecting hopper, a slag collection bucket is provided at the top of the trolley, and the slag collection bucket is located at the bottom of the discharge port of the collecting hopper.

[0010] By adopting the above technical solution, a collection mechanism is set up to collect the iron beans, which facilitates subsequent cleaning.

[0011] The present invention is further configured such that: a fixing plate is bolted to the inner wall of the fixing frame, and the fixing plate is rotatably sleeved with the surface of the rotating shaft.

[0012] By adopting the above technical solution, the rotating shaft is fixed by setting a fixing plate, thereby improving stability.

[0013] The present invention is further configured such that: bolts are provided through the inner walls of the lifting plate and the electromagnetic chuck, and nuts are threaded onto the surface of the bolts.

[0014] By adopting the above technical solution and setting bolts and nuts, the electromagnetic chuck can be easily assembled and disassembled.

[0015] The present invention is further configured such that: four guide rods are bolted to the top of the lifting plate, and the guide rods are slidably sleeved with the inner wall of the slide block.

[0016] By adopting the above technical solution and setting guide rods, the stability of the lifting platform is improved.

[0017] The present invention is further configured such that baffles are bolted between the inner walls of the collecting hopper.

[0018] By adopting the above technical solution, a baffle is set to limit the movement of the trolley, making it easy to align the discharge ports of the slag collection bucket and the collection hopper, thus facilitating use.

[0019] The present invention is further configured such that limit plates are bolted to both ends of the slide rail.

[0020] By adopting the above technical solution, a limiting plate is set to prevent the slide from slipping out and improve stability.

[0021] In summary, this utility model has the following beneficial effects:

[0022] This invention uses a hydraulic lifting rod to lower an electromagnetic chuck. Once the chuck is close to the surface of the sand box, it is energized and magnetized, thus picking up iron beads and iron blocks from the surface of the sand box. The chuck then rises and moves to the slag collection bucket, where it is de-energized and demagnetized, releasing the adsorbed iron beads. It then returns to the adsorption station. This design offers high adsorption efficiency, avoids unnecessary downtime, greatly improves production efficiency, and saves labor. Attached Figure Description

After approaching the surface of the sand box, the electromagnetic chuck 10 is energized and magnetized, which can pick up the iron beans and iron blocks on the surface of the sand box. Then the electromagnetic chuck 10 is raised and moved to the slag collection bucket 17 to de-energize and release the adsorbed iron beans. Then it returns to the adsorption station. The adsorption efficiency is high, avoiding unnecessary downtime, greatly improving production efficiency, and also saving labor.

[0030] refer to Figure 2 and Figure 3 The moving mechanism 6 includes a slide rail 12, with first rollers 13 rollingly connected to the top and bottom of the slide rail 12. The first rollers 13 are bolted to the surface of the slide block 5.

By setting the moving mechanism 6, the first rollers 13 and the second rollers 14 limit the slide block 5, thereby reducing friction with the slide rail 12, reducing energy consumption, and improving stability.

[0031] refer to Figure 1 The collection mechanism 11 includes a collection hopper 15, which is located at the bottom of the fixed frame 1. A trolley 16 is provided at the bottom of the collection hopper 15, and a slag collection bucket 17 is provided at the top of the trolley 16.

[0037] Brief description of the operation: When the sand box after pouring and cooling passes through this device, the hydraulic lifting rod 8 drives the lifting plate 9 to lower the electromagnetic chuck 10. When the electromagnetic chuck 10 approaches the surface of the sand box, it is energized and magnetized. The magnetic force can be adjusted according to the actual adsorption situation, which can pick up the iron beans and iron blocks on the surface of the sand box. Then, the hydraulic lifting rod 8 drives the electromagnetic chuck 10 to rise. Then, the motor 7 rotates and drives the rotating shaft 2 to rotate. The rotating shaft 2 rotates and drives the sprocket 3 to rotate. The rotating sprocket 3 rotates and drives the chain 4 to move the slide 5, moving the electromagnetic chuck 10 to the collection hopper 15. Then, the power is turned off and the magnetization is demagnetized, and the adsorbed iron beans are released. The iron beans enter the slag collection bucket 17 from the collection hopper 15 for collection. Then, the motor 7 rotates in the opposite direction, so that the electromagnetic chuck 10 returns to the adsorption position. This cycle is repeated. The reciprocating efficiency matches the efficiency of the static pressure production line. After the slag collection bucket 17 is full, it is manually pushed away for cleaning.
