Description

Technical Field

[0001] This utility model relates to the field of casting production technology, and in particular to a device for cleaning molding sand from the surface of castings. Background Technology

[0002] Molding sand refers to the material used in the casting process to make sand molds and cores. It is mainly composed of raw sand, binder, and additives mixed in a certain proportion. The main function of molding sand is to form the external shape of the casting and to support and protect the casting when molten metal is poured in.

[0003] After casting, molding sand adheres to the surface of the casting due to factors such as compression and heating. In order to remove the casting and recycle the molding sand, it is necessary to effectively clean the molding sand on the surface of the casting. The existing cleaning method mainly involves hammering to break the surface molding sand, and then cleaning it with a high-pressure water gun. Hammering is inefficient, requires a lot of physical strength from workers, and also carries the risk of damaging the casting. The high-pressure water flow causes a large amount of water to enter the molding sand, which is not only detrimental to the recycling of molding sand, but also generates a lot of wastewater. Therefore, a molding sand cleaning device is needed to assist in shaking off the molding sand, reduce the molding sand residue during washing, and facilitate the recycling of molding sand. Utility Model Content

[0004] This utility model addresses the deficiencies in the prior art by providing a device for cleaning molding sand from the surface of castings.

[0005] This utility model is achieved through the following technical solution:

[0006] A casting surface sand cleaning device includes a support mechanism, a mounting frame, a first hydraulic cylinder, a vibration device, and an air blowing device. The mounting frame is fixedly installed on the top of the support mechanism. The first hydraulic cylinder is connected to the top of the mounting frame. The vibration device is installed at the telescopic end of the first hydraulic cylinder. The air blowing device is fixed to the side of the mounting frame. The support mechanism includes a support platform, a barrier, a connecting frame, a guide cover, and a limiting seat. The barrier is fixedly installed on the upper surface of the support platform. The connecting frame is fixedly installed inside the barrier. The guide cover is fixedly installed at the top of the connecting frame. The limiting seat is fixedly installed at the top of the guide cover. The vibration device includes a connecting plate, a guide tube, a telescopic rod, a connecting rod, a spring, a pressure plate, and a vibrator. The connecting plate is fixedly installed at the telescopic end of the first hydraulic cylinder. The guide tube is fixedly installed at the bottom outer edge of the connecting plate. The telescopic rod is clamped at the bottom of the guide tube. The connecting rod is fixedly installed at the top of the telescopic rod. The spring is sleeved on the outside of the connecting rod. The pressure plate is fixedly installed at the bottom of the telescopic rod. The vibrator is installed at the top of the pressure plate.

[0007] In a preferred embodiment of the present invention, the air blowing device includes a second oil cylinder, an air inlet pipe, a guide block and an air nozzle. The second oil cylinder is connected to the outside of the mounting bracket. The air inlet pipe is fixedly disposed on the telescopic end of the second oil cylinder. The guide block is fixedly disposed on the outer surface of the air inlet pipe. The air nozzle is snapped into one end of the air inlet pipe.

[0008] The air blowing equipment uses an external high-pressure air source to spray airflow from top to bottom onto the surface of the forging, achieving an effective cleaning effect.

[0009] In a preferred embodiment of the present invention, the mounting bracket has a sliding groove on its side, and the guide block has slots on both sides. The guide block is engaged in the sliding groove on the side of the mounting bracket, and the slots on both sides are engaged in the outer side of the sliding groove on the inner side of the mounting bracket.

[0010] The guide block is fitted into the sliding groove on the side of the mounting bracket, which not only supports the air intake pipe but also provides effective guidance.

[0011] In a preferred embodiment of the present invention, the top end of the connecting rod extends through and to the top outer side of the connecting plate, and a limiting piece is fixedly provided at the top end of the connecting rod;

[0012] The first hydraulic cylinder presses down, pressing the bottom of the vibrator against the top of the casting. At this time, the telescopic rod is pressed into the guide tube, so that the spring can effectively exert pressure, thereby ensuring that the vibration of the vibrator is transmitted to the surface of the casting, which facilitates the breaking and shaking off of the molding sand on the surface of the casting.

[0013] In a preferred embodiment of the present invention, a molding sand collection groove is provided on the upper surface of the support platform in the middle of the enclosure, and the outer side of the guide cover is inclined downward.

[0014] In a preferred embodiment of the present invention, one end of the vibrator extends through and to the outer side of the bottom of the pressure plate, and the vibrating end of the vibrator is located on the outer side of the top of the limiting seat.

[0015] The beneficial effects of this utility model are:

[0016] The casting surface molding sand cleaning device applies pressure to the top and bottom of the casting and vibrates the compressed casting. The high-frequency vibrator transmits the vibration to the surface of the casting, causing the molding sand on the surface of the casting to break and fall off. The enclosure covers the fallen molding sand, allowing it to fall to the bottom of the support platform. The air blowing equipment sprays high-pressure gas from top to bottom to further clean the surface of the casting, thereby facilitating the recycling of molding sand and reducing the amount of molding sand residue on the surface of the casting when cleaning with a high-pressure water gun.

[0023] like Figure 1-4 The device for cleaning molding sand from the surface of a casting includes a support mechanism 1, a mounting frame 2, a first hydraulic cylinder 3, a vibration device 4, and an air blowing device 5. The mounting frame 2 is fixedly mounted on the top of the support mechanism 1. The first hydraulic cylinder 3 is connected to the top of the mounting frame 2. The vibration device 4 is located at the telescopic end of the first hydraulic cylinder 3. The air blowing device 5 is fixed to the side of the mounting frame 2. The support mechanism 1 includes a support platform 11, a retaining wall 12, a connecting frame 13, a guide cover 14, and a limiting seat 15. The retaining wall 12 is fixedly mounted on the upper surface of the support platform 11. The connecting frame 13 is fixedly mounted inside the retaining wall 12. The guide cover 14 is fixedly mounted on the side of the support platform 11. The top of the connecting frame 13 and the limiting seat 15 are fixedly installed on the top of the guide cover 14. The vibration device 4 includes a connecting plate 41, a guide tube 42, a telescopic rod 43, a connecting rod 44, a spring 45, a pressure plate 46 and a vibrator 47. The connecting plate 41 is fixedly installed at the telescopic end of the first oil cylinder 3. The guide tube 42 is fixedly installed at the bottom outer edge of the connecting plate 41. The telescopic rod 43 is clamped at the bottom of the guide tube 42. The connecting rod 44 is fixedly installed at the top of the telescopic rod 43. The spring 45 is sleeved on the outside of the connecting rod 44. The pressure plate 46 is fixedly installed at the bottom of the telescopic rod 43. The vibrator 47 is installed on the top of the pressure plate 46.

[0024] Specifically, the air blowing device 5 includes a second hydraulic cylinder 51, an air inlet pipe 52, a guide block 53, and a jet nozzle 54. The second hydraulic cylinder 51 is connected to the outside of the mounting frame 2. The air inlet pipe 52 is fixedly installed at the telescopic end of the second hydraulic cylinder 51. The guide block 53 is fixedly installed on the outer surface of the air inlet pipe 52. The jet nozzle 54 is snapped into one end of the air inlet pipe 52. A sliding groove is provided on the side of the mounting frame 2. Slots are provided on both sides of the guide block 53. The guide block 53 is snapped into the sliding groove on the side of the mounting frame 2. The slots on both sides are snapped into the outside of the sliding groove on the inner side of the mounting frame 2. The top of the connecting rod 44 passes through and extends to the top outer side of the connecting plate 41. A limiting piece is fixedly installed at the top of the connecting rod 44. A molding sand collection trough is provided on the upper surface of the support platform 11, located in the middle of the enclosure 12. The outer side of the material guide cover 14 is inclined downward. One end of the vibrator 47 passes through and extends to the bottom outer side of the pressure plate 46. The vibrating end of the vibrator 47 is located on the top outer side of the limiting seat 15.

[0025] In this embodiment, the casting that needs to be cleaned of surface molding sand is first placed inside the top of the limiting seat 15. The top slot of the limiting seat 15 has an effective limiting effect, and its bottom is set up to facilitate the discharge of the molded sand. Then, the first hydraulic cylinder 3 extends and the connecting plate 41 descends until the bottom of the vibrator 47 contacts the top of the casting. The first hydraulic cylinder 3 extends further until the telescopic rod 43 extends into the guide tube 42. The top of the connecting rod 44 pushes out from the top of the connecting plate 41, and the spring 45 is compressed and contracted. Its reaction force firmly presses the bottom of the vibrator 47 against the top of the casting. Then, the vibrator 47 is started, and high-frequency vibration is transmitted to the surface of the casting, causing the casting to vibrate, thereby loosening and breaking the molding sand on the surface of the casting and shaking it off.

[0026] Furthermore, a high-pressure air source is connected to the end of the air inlet pipe 52. After the airflow passes through the air inlet pipe 52, it is ejected from the air outlet at the end of the jet nozzle 54. Since the jet nozzle 54 is fan-shaped and its air outlet is tilted downward, it can better act on the surface of the casting. At this time, the second hydraulic cylinder 51 retracts, driving the air inlet pipe 52 to descend, causing the guide block 53 to slide within the mounting frame 2, so that the airflow acts on the surface of the casting from top to bottom, further effectively cleaning the molding sand on the surface of the casting. The shaken and blown molding sand will be effectively blocked by the enclosure 12 and fall to the bottom of the support platform 11 through the molding sand collection groove on the surface of the support platform 11, which facilitates the collection and reuse of molding sand.
