DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0025] Reference Figure 1-Figure 6 A bonded abrasive cold press forming device comprises a machine body 1, an upper die 2 and a lower die 3. A hydraulic cylinder 4 is fixedly mounted on the top wall of the machine body 1. A circular placement groove 5 is provided at the bottom of the machine body 1. The lower die 3 is vertically placed in the placement groove 5. The upper die 2 is located at the bottom end of the driving shaft of the hydraulic cylinder 4. The left and right side walls of the lower die 3 and the upper die 2 are both horizontally provided with slots 6.

[0026] A mounting block is fixedly installed at the bottom end of the driving shaft of the hydraulic cylinder 4, and a straight groove is vertically opened on the lower surface of the mounting block. A plug rod 17 is fixedly installed on the upper surface of the upper mold 2, and the plug rod 17 is inserted into the straight groove. Spring rods 7 are fixedly installed on the left and right side walls of the mounting block, and a plug plate 8 is fixedly installed on one end of the spring rod 7. A mounting plate 9 is provided below the plug plate 8, and a slide groove is vertically opened on the upper surface of the mounting plate 9. Two plug plates 8 are respectively slidably inserted in two slide grooves. Locking rods 10 are fixedly installed on the surfaces of the plug plate 8 and the mounting plate 9, and one end of the multiple locking rods 10 is respectively inserted in multiple slots 6. Inclined plates 11 are symmetrically fixedly installed on the inner wall of the body 1, and a pressure rod 12 is fixedly installed on the surface of the plug plate 8. The lower surfaces of the two pressure rods 12 correspond to the upper surface positions of the two inclined plates 11 respectively.

[0027] When the upper mold 2 and the lower mold 3 need to be installed, the lower mold 3 is first placed vertically in the placement groove 5, and then the insertion rod 17 at the top of the upper mold 2 is controlled to be inserted into the straight groove until the top of the upper mold 2 abuts against the lower surface of the mounting block. At this time, the upper mold 2 and the lower mold 3 are rotated so that the two slots 6 on their side walls correspond to the positions of the multiple locking rods 10 respectively, and then the multiple locking rods 10 are controlled to be inserted into the multiple slots 6 respectively, so that the upper mold 2 and the lower mold 3 can be locked. When disassembly is required, the upper mold 2 and the lower mold 3 can be unlocked by controlling the two spring rods 7 to stretch and controlling the ends of the multiple locking rods 10 to be moved out of the multiple slots 6 respectively, which is convenient and quick.

[0028] When the device is working, that is, when the upper mold 2 moves downward, the two plug plates 8 will move vertically in the two slide grooves respectively, and the two pressure rods 12 will slide and contact with the two inclined plates 11 respectively. Under the action of the inclined surface pressure, the two spring rods 7 will shrink together, and multiple locking rods 10 will move toward the slot 6. The spring rod 7 cannot be stretched at this time, thereby strengthening the locking of the upper mold 2 and the lower mold 3, avoiding the spring rod 7 from being stretched by the vibration force during the operation of the device, thereby improving the stability of locking the upper mold 2 and the lower mold 3. When the device is not working, that is, the upper mold 2 is at the top, the pressure rod 12 will not contact the inclined plate 11. By pulling the spring rod 7 to stretch, the end of the locking rod 10 is controlled to move out of the slot 6 to release the lock of the upper mold 2 and the lower mold 3, which is convenient, and the locking and unlocking of the upper mold 2 and the lower mold 3 can be completed at the same time, avoiding the cumbersome steps of using screw and nut fixings, and improving the efficiency of mold replacement.

[0029] A spherical groove is formed on the lower surface of the mounting plate 9, in which a rolling ball is embedded and rolled. The rolling ball is in rolling contact with the inner bottom wall of the body 1, and the rolling ball can reduce the friction between the mounting plate 9 and the inner bottom contact surface of the body 1.

[0030] A limiting assembly is provided on the surface of the mounting plate 9, and the limiting assembly is used to limit the downward movement distance of the upper mold 2. The limiting assembly includes a threaded rod 13 and a limiting plate 14 threadedly sleeved on the threaded rod 13. A sliding opening 15 is vertically opened on the surface of the mounting plate 9, and a fixing plate is fixedly installed on the surface of the mounting plate 9. The threaded rod 13 is vertically rotatably installed on the upper surface of the fixing plate. One end of the limiting plate 14 passes through the sliding opening 15. A scale 16 is provided on the surface of the mounting plate 9. An adjusting wheel is fixedly installed on the top of the threaded rod 13, and the surface of the adjusting wheel is provided with anti-slip grooves;

[0031] By rotating the threaded rod 13, the limiting plate 14 threadedly sleeved on the threaded rod 13 will move vertically under the limiting action of the sliding mouth 15, and the distance between the limiting plate 14 and the inserting plate 8 can be adjusted, so as to limit the downward movement distance of the upper mold 2 and control the length of the upper mold 2 entering the lower mold 3, so as to realize the control of the thickness of the finished product of the consolidated abrasive tool, better meet the actual use needs, and improve the practicality. According to the scale 16, the limiting plate 14 can be quickly adjusted to move to the appropriate position.

[0032] In the utility model, when it is necessary to install the upper mold 2 and the lower mold 3, the lower mold 3 is first placed vertically in the placement groove 5, and then the insertion rod 17 at the top of the upper mold 2 is controlled to be inserted into the straight groove until the top of the upper mold 2 is against the lower surface of the mounting block. At this time, the upper mold 2 and the lower mold 3 are rotated so that the two slots 6 on their side walls correspond to the positions of the multiple locking rods 10 respectively, and then the multiple locking rods 10 are controlled to be inserted into the multiple slots 6 respectively, so that the locking of the upper mold 2 and the lower mold 3 can be completed. When disassembly is required, it is only necessary to control the two spring rods 7 to stretch and control the ends of the multiple locking rods 10 to move out of the multiple slots 6 respectively to release the locking of the upper mold 2 and the lower mold 3, which is convenient and quick.

[0033] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
