Description

Technical Field

[0001] This utility model belongs to the technical field of sand removal equipment, specifically, it relates to a sand removal device for silica sol investment casting precision casting parts. Background Technology

[0002] In the process of silica sol investment casting, after casting, the surface and interior of the parts are often covered with impurities such as sand particles. If these impurities are not removed in time, they will not only affect the appearance quality of the parts, but may also adversely affect their subsequent processing and performance. Traditional sand removal methods often use manual knocking or simple mechanical devices for cleaning. These methods are not only inefficient, but also often fail to guarantee the cleaning effect. A search revealed a silica sol precision casting vibrating shell sand removal machine with publication number CN222001831U, which relates to the field of precision casting. A silica sol precision casting vibrating shell sand removal machine includes a processing box, a first box door rotatably connected to the material inlet of the processing box, and symmetrical openings on both sides of the processing box. It also includes a drive shaft disposed in the opening, and a shock-absorbing rubber ring fixedly connected to the drive shaft at the opening. However, the disadvantage of the above technical solution is that it mainly relies on the vibration generated by the vibrator to clean the sand particles on the surface of the parts. However, this cleaning method may not be ideal for some sand particles or impurities with strong adhesion. Especially when dealing with components that are complex in shape or have delicate internal structures, vibration alone is often insufficient to achieve a comprehensive and thorough cleaning effect. Furthermore, vibration treatment may cause some damage to the components themselves, such as creating micro-cracks or deformation, thereby affecting their quality and performance.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0027] A sand-removing device for precision casting parts using silica sol investment casting includes an angle adjustment module 1 and a water spray module mounted on a support platform 3.

[0028] The support platform 3 is a movable bracket and is equipped with a push handle, which can be pushed to move it to a suitable location.

[0029] The angle adjustment module 1 is used to place accessories and drive the accessories to rotate to adjust their angle. It includes a support frame 102, within which a placement groove 103 is rotatably disposed. The placement groove 103 has several evenly arranged mounting holes 1031, which correspond to through holes on the accessories for fixing them in place within the placement groove 103 using screws. The support frame 102 has an opening on one side; this U-shaped opening facilitates support for the placement groove 103. The placement groove 103 corresponds to one of the nozzles 6 of the water spray module. The side is a recessed placement area. The upper and lower ends of the support frame 102 are respectively rotatably connected to the upper and lower middle round shafts fixed in the middle of the placement groove 103. The upper round shaft of the placement groove 103 is fixedly connected to the output shaft of the first motor 101. The first motor 101 is fixed on the support frame 102. The first motor 101 should also be provided with a motor cover. The motor cover can protect the first motor 101 and is fixed on the support frame 102. The first motor 101 can drive the placement groove 103 to rotate, thereby driving the internal accessories to rotate.

[0030] It also includes a second motor 2, the output shaft of which is fixedly connected to the end of the rotating shaft of the support frame 102. The rotating shaft of the support frame 102 is fixed to the center of the other side of the support frame 102. The rotating shaft of the support frame 102 is rotatably connected to the support platform 3. The second motor 2 is fixedly connected to the support platform 3. The second motor 2 is also provided with a matching motor cover. The motor cover serves as a protective cover and is fixed on the support platform 3. The rotation of the output shaft of the second motor 2 can drive the support frame 102 to rotate, thereby driving the placement slot 103 to rotate.

[0031] In this embodiment, the placement trough 103 is rotated in two different directions through the coordinated action of the first motor 101 and the second motor 2. The first motor 101 drives the placement trough 103 to rotate around the circular shaft fixed in the middle of its upper and lower sides to adapt to the sand cleaning requirements in different directions. The second motor 2 drives the support frame 102 to rotate around the pivot fixed on the support platform 3. This rotation method further expands the angle adjustment range of the accessory. Through the cooperation of these two motors, the accessory can be flexibly adjusted in three-dimensional space, thereby ensuring that the sand cleaning process can be carried out comprehensively and thoroughly.

[0032] The water spray module is mounted on the support platform 3 and includes a water tank, a water pump, a water pipe 5, and a nozzle 6. It is used to spray water to rinse the accessories placed in the placement tank 103. The water pipe 5 is fixed on the support platform 3, and one end of the water pipe 5 is fixedly connected to a connecting pipe 502. The nozzle 6 is installed at the end of the connecting pipe 502. The nozzle 6 can be fixedly installed at the end of the connecting pipe 502 and the spray angle can be adjusted by adjusting the angle of the connecting pipe 2. Alternatively, it can be an existing universal adjustable nozzle that can be manually rotated 360 degrees to adjust the angle. The nozzle 6 is positioned corresponding to the placement tank 103. The connecting pipe 502 is a flexible metal conduit. A switch 501 is installed on the water pipe 5. The other end of the water pipe 5 is fixedly connected to the outlet of the water pump on the water tank through a flexible hose. When the switch 501 and the water pump on the water pipe 5 are turned on, water can be sprayed out through the nozzle 6 to rinse the accessories placed in the placement tank 103 for sand removal. The flexible metal conduit allows for easy adjustment of the angle and position of the nozzle 6.

[0033] Example 2: The support platform 3 has four downward-facing drainage channels formed by four connected inclined surfaces 301 on its lower side corresponding to the placement trough 103. These channels facilitate the collection of wastewater. A drainage pipe 302 is installed at the bottom of each drainage channel, and a discharge valve is mounted on the pipe 302. When the discharge valve is opened, wastewater is discharged from the pipe 302. When the valve is closed, the wastewater collects in the drainage channel. A holding tank 4 is located below the support platform 3 and below the drain outlet of the drainage pipe 302, and is used to hold the wastewater. The holding tank 4 is used to collect wastewater generated during the sand cleaning process. The holding tank 4 is placed on the support platform 3, and handles are provided at both ends for easy handling and emptying of the wastewater.

[0034] Example 3: A filter tank 303 is installed at the upper inlet of the drainage pipe 302 to filter impurities.

[0035] Example 4: During use, since some accessories do not have through holes, a positioning module 7 is provided on the side of the placement slot 103 away from the second motor 2. The positioning module 7 includes a pair of connecting rods 704, which are slidably connected to the placement slot 703. One end of the connecting rod 704 is screwed with a bolt 705, and the bolt 705 is fixedly connected to a positioning block 703 at one end of the placement slot 703. The connecting rod 704 is L-shaped, and the other end is fixedly connected to a slider 702. The slider 702 is slidably connected to a groove 701 opened on one side of the placement slot 703. A guide shaft is provided in the groove 701. There is a preload between the slider 702 and the guide shaft. The preload provides a certain damping when the slider 702 slides on the guide shaft, preventing it from sliding easily. To ensure the stability of the positioning block 703 during positioning, when positioning accessories without through holes is required, the accessory is first placed in the placement groove 103, then the connecting rod 704 is slid to adjust the position of the slider 702 on the guide shaft, thereby adjusting the position of the connecting rod 704 so that the positioning block 703 is close to the accessory. By rotating the bolt 705, the positioning block 703 is made to press tightly against the accessory, thus achieving the positioning of the accessory. This allows the positioning block 703 to adjust its position according to the height of the accessory. Users only need to rotate the bolt 705 to quickly adjust the position of the positioning block 703 without complicated tools or steps, greatly improving the applicability and working efficiency of the sand cleaning device. The guide shaft fixes the placement groove 103, the guide shaft passes through the slider 702, and the slider 702 is fixedly connected to the other end of the connecting rod 704.

[0036] Example 5: The positioning block 703 is made of a flexible material, such as rubber or silicone, to adapt to accessories of different shapes and sizes, while avoiding scratches or damage to the surface of the accessories.

[0037] In conjunction with Embodiments 1-5, the method of using this utility model is as follows:

[0038] First, move the silica sol investment casting precision casting parts sand removal device to a suitable working location. The support platform 3 can be easily moved by pushing the handle.

[0039] If the accessory has a through hole, place the accessory in the placement slot 103 so that the through hole on the accessory corresponds to the mounting hole 1031 on the placement slot 103. Then screw in the screw to securely fix the accessory in the placement slot 103. If the accessory does not have a through hole, use the positioning module 7 for positioning. Slide the connecting rod 704, adjust the position of the slider 702 on the guide shaft so that the positioning block 703 is close to the accessory, and rotate the bolt 705 to make the positioning block 703 press tightly against the accessory to complete the positioning.

[0040] Next, according to the sand removal requirements, the first motor 101 and the second motor 2 are started. The first motor 101 drives the placement groove 103 to rotate around the circular shaft fixed in the middle of its upper and lower sides. The second motor 2 drives the support frame 102 to rotate around the rotating shaft fixed on the support platform 3. The synergistic effect of the two motors allows the placement groove 103 to be flexibly adjusted in three-dimensional space, ensuring that all parts of the accessories can be fully exposed during the sand removal process, so as to carry out comprehensive and thorough sand removal.

[0041] Turn on the switch 501 and water pump on the water pipe 5. Water flows through the water tank, water pump, hose, water pipe 5 and flexible metal conduit, and finally sprays out from the nozzle 6 to rinse the accessories placed in the placement trough 103. The flexible metal conduit design allows the angle and position of the nozzle 6 to be adjusted at will to meet the sand cleaning needs of accessories of different shapes and sizes.

[0042] During the sand cleaning process, the wastewater will converge along the downward-concave drainage channel formed by the inclined surface 301. Open the discharge valve on the drainage pipe 302, and the wastewater will be discharged from the drainage pipe 302 and enter the holding tank 4. The filter tank 303 at the upper inlet of the drainage pipe 302 can filter out impurities in the wastewater to prevent them from clogging the drainage pipe 302 or affecting subsequent treatment. When the wastewater in the holding tank 4 accumulates to a certain level, it can be carried to a designated location by the handle to empty the internal sewage for continued use.

[0043] After the sand removal is completed, turn off the switch 501 and water pump on the water pipe 5 to stop the water spraying. Remove the accessories from the placement tank 103 and check the sand removal effect. If the sand removal effect is not ideal, the above sand removal steps can be repeated until a satisfactory sand removal effect is achieved.

[0044] The above-disclosed embodiments are merely specific examples of this utility model. However, this utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
