Description

Technical Field

[0001] This utility model relates to the field of precision casting demolding technology, specifically to an ultrasonic vibration-assisted precision casting demolding device. Background Technology

[0002] Precision castings refer to metal parts formed through precision casting processes. Precision casting is an advanced technology that uses precise molding methods to obtain castings with high-precision dimensions and good surface finish. Compared to traditional sand casting, precision casting produces castings with more accurate dimensions and better surface finish. Ultrasonic vibration demolding of precision castings is a method that uses ultrasonic vibration technology to assist in demolding. Specifically, this method applies high-frequency vibration between the casting and the mold, reducing the adhesion between them and making it easier to remove the casting from the mold.

[0003] Existing ultrasonic demolding devices do not have the function of protecting castings. Castings that fall off under the action of ultrasonic vibration will fall directly onto the metal table. Precision castings are easily damaged by the impact force generated by the fall, which will affect the production qualification rate of precision castings.

[0004] Therefore, those skilled in the art provide an ultrasonic vibration-assisted precision casting demolding device to solve the problems mentioned in the background art. Utility Model Content

This ring structure can receive the falling castings. The impact force generated by the castings can be driven by the ring structure to make the buffer support foot slide on the outer wall of the smooth rod, while compressing the elastic element, thereby absorbing the impact force and ensuring the safety of the castings. At the same time, the rubber sleeve can also produce elastic deformation to absorb the impact force on the castings, fully ensuring the safety of the shaken castings and improving the production qualification rate of castings.

[0016] 2. This utility model, through the overall design of the lower die head replacement mechanism, inserts the fitting block into the inside of the groove, and then tightens the threaded part to complete the installation of the lower die head body.

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figures 1-5 As shown, this utility model provides a technical solution: an ultrasonic vibration-assisted precision casting demolding device, including a worktable 1, a circular base 14 fixedly installed on the top of the worktable 1, a casting protection mechanism 2 provided on the circular base 14, and a lower mold head replacement mechanism 3 provided at the center of the top of the circular base 14.

[0026] The casting protection mechanism 2 includes a support foot 21, which is fixedly connected to the outer wall of the circular base 14. A smooth rod 211 is fixedly installed on the top of the support foot 21. A buffer support foot 213 is slidably connected to the outer wall of the smooth rod 211. A connecting plate 212 is detachably connected to the top of the support foot 21. An elastic element 214 is fixedly installed on the top of the connecting plate 212. The top of the elastic element 214 is movably connected to the bottom of the buffer support foot 213. When the casting is shaken off, it will generate an impact force. The buffer support foot 213 can slide downward on the outer wall of the smooth rod 211 and compress the elastic element 214 at the same time. The elastic deformation generated by the elastic element 214 absorbs the impact force, fully ensuring the safety of the shaken casting. The connecting plate 212 is installed on the top of the support foot 21 by bolts. After the elastic element 214 is worn out, the user can replace the connecting plate 212 and the elastic element 214 on its top by removing and installing bolts, thus extending the overall service life of the structure.

[0027] As one implementation method in this embodiment, please refer to Figure 1 As shown, a lifting column 11 is fixedly installed on the top of the workbench 1. An ultrasonic generator 12 is fixedly installed on the telescopic end of the lifting column 11. A vibrating mold head 13 is fixedly installed on the bottom of the ultrasonic generator 12. After the casting mold is stuck on the top of the lower mold head body 34, the ultrasonic generator 12 is controlled to drive the vibrating mold head 13 to vibrate. Then, the lifting column 11 is controlled to retract, which can drive the vibrating mold head 13 to move down, so as to realize the function of ultrasonic vibration demolding of the casting mold. The ultrasonic generator 12 and the vibrating mold head 13 are existing devices, which use an oscillation frequency of 15kHz.

[0028] As one implementation method in this embodiment, please refer to Figure 4 As shown, an outer ring seat 22 is fixedly installed on the outer wall of the buffer support 213, and multiple connecting rods 221 are fixedly installed on the inner wall of the outer ring seat 22. The end of the connecting rod 221 away from the outer ring seat 22 is fixedly connected to an inner ring seat 222. Through the design of the outer ring seat 22, the connecting rods 221 and the inner ring seat 222, a ring structure can be formed, which can receive the falling casting.

[0029] As one implementation method in this embodiment, please refer to Figure 4 As shown, multiple support rods 223 are fixedly connected to the inner wall of the outer ring seat 22. Rubber sleeves 224 are fixedly sleeved on the outer walls of the connecting rods 221 and the support rods 223. Through the design of the support rods 223, the gap between the connecting rods 221 can be reduced. The rubber sleeves 224 can also produce elastic deformation to absorb the impact force on the casting and fully ensure the safety of the casting that is shaken off.

[0030] As one implementation method in this embodiment, please refer to Figure 5As shown, the lower die head replacement mechanism 3 includes a die base 31, which is fixedly installed at the center of the top of the workbench 1. A groove 32 is provided on the top of the die base 31, and a fitting block 33 is movably inserted into the inner cavity of the groove 32. The lower die head body 34 is fixedly installed on the top of the fitting block 33. By inserting or removing the fitting block 33 into the inner cavity of the groove 32, the lower die head body 34 can be replaced to accommodate castings of different specifications.

[0031] As one implementation method in this embodiment, please refer to Figure 5 As shown, a threaded part 35 is threadedly connected to the outer wall of the groove 32. The threaded end of the threaded part 35 extends into the inner cavity of the groove 32 and is rotatably connected to a translation plate 37. A limit rod 36 is fixedly connected to the outer wall of the translation plate 37. The limit rod 36 is slidably connected to the inner wall of the mold base 31. When the threaded part 35 is rotated manually, the limit rod 36 will slide and limit the translation plate 37, thereby causing the translation plate 37 to move toward or away from the mating block 33, which is convenient for positioning or releasing the positioning of the mating block 33.

[0032] As one implementation method in this embodiment, please refer to Figure 5 As shown, an insert block 38 is fixedly connected to the side of the translation plate 37 away from the threaded part 35. The insert block 38 is movably inserted into the inside of the mating block 33. After the mating block 33 is inserted into the inside of the groove 32, the insert block 38 can be driven to insert into the mating block 33 by rotating the threaded part 35 to position the mating block 33. Alternatively, the threaded part 35 can be rotated to drive the insert block 38 out of the inside of the mating block 33 to release the positioning of the mating block 33.

[0033] Working principle: During use, the casting mold is clamped on the top of the lower mold head body 34. The ultrasonic generator 12 is controlled to drive the vibrating mold head 13 to vibrate. Then, the lifting column 11 is controlled to retract, which can drive the vibrating mold head 13 to move down, realizing the function of ultrasonic vibration demolding of the casting mold. Through the design of the outer ring seat 22, connecting rod 221, inner ring seat 222 and support rod 223, a ring structure can be formed. This ring structure can receive the falling casting. The impact force generated by the casting can be absorbed through the ring. The structure drives the buffer support 213 to slide on the outer wall of the smooth rod 211, while compressing the elastic element 214, thereby absorbing the impact force. During maintenance, if the lower die head body 34 needs to be replaced, the threaded part 35 is rotated to drive the embedded block 38 to be withdrawn from the inside of the mating block 33. The mating block 33 is inserted or pulled out in the inner cavity of the groove 32, which can realize the function of replacing the lower die head body 34. The threaded part 35 is rotated again to drive the embedded block 38 to be inserted into the mating block 33.
