[0028] Please refer to Figures 1 - 5 , the present utility model provides a technical solution: a die replaceable rubber part stamping and forming device, including a base 1, a plurality of fixing rods 10 are connected to the top of the base 1, and the other ends of the plurality of fixing rods 10 are connected to the same fixing block 7. A first through hole 6 is opened in the fixing block 7, a cylinder 5 is connected to the inner wall of the first through hole 6, the ejector rod of the cylinder 5 is connected to a moving block 9, and two disassembly and assembly mechanisms 3 are provided at the top of the base 1 and the bottom of the moving block 9 respectively. A cooling mechanism 4 is provided on one side of the fixing block 7 and one side of the moving block 9. A plurality of second through holes 8 are opened in the moving block 9, and the inner wall of the second through hole 8 is slidably connected to the outer wall of the fixing rod 10;

[0029] Mounting seats 12 are attached to the top of the base 1 and the bottom of the moving block 9 respectively. A lower die 14 is connected to the top of one of the mounting seats 12, and an upper die 13 is connected to the bottom of the other mounting seat 12. The disassembly and assembly mechanism 3 includes a clamping groove 305 opened on one side of the mounting seat 12. A clamping block 302 is attached to the inner wall of the clamping groove 305. One side of the clamping block 302 extends outside the clamping groove 305 and is connected to a connecting plate 303. Two stroke grooves 18 are opened at the top of the base 1 and the bottom of the moving block 9 respectively. One side of the clamping block 302 is connected to a sliding sleeve 306. The outer wall of the sliding sleeve 306 is slidably connected to the inner wall of the stroke groove 18. One side of the sliding sleeve 306 is connected to a first spring 307, and the other end of the first spring 307 is connected to one side of the inner wall of the stroke groove 18. A sliding rod 301 is slidably connected to the inner wall of the sliding sleeve 306. Both ends of the sliding rod 301 are connected to both sides of the inner wall of the stroke groove 18 respectively. The first spring 307 is sleeved outside the sliding rod 301. A fixing sleeve 304 is slidably connected to the outer wall of the clamping block 302. One side of two of the fixing sleeves 304 is connected to the top of the base 1, and one side of the other two fixing sleeves 304 is connected to the bottom of the moving block 9.

[0030] The specific implementation method is as follows: the connecting plate 303 is driven to move the clamping block 302 so that the clamping block 302 can be disengaged from the clamping groove 305, thereby releasing the restriction on the mounting seat 12. At the same time, the clamping block 302 can drive the first spring 307 to be compressed through the sliding sleeve 306, so that the first spring 307 generates elastic force. The arrangement of the sliding sleeve 306, the sliding rod 301 and the fixing sleeve 304 can make the clamping block 302 more stable when moving. Then, the mounting seat 12 is pushed to drive the limit block 11 to move, so that the limit block 11 is separated from the limit groove 2, so that the two mounting seats 12 can be removed from the base 1 and the moving block 9, and then the upper mold 13 and the lower mold 14 can be removed from the stamping forming device. At this time, the first spring 307 releases its elastic force to drive the sliding sleeve 306 and the clamping block 302 To restore to the original position, during installation, the limit block 11 is inserted into the limit groove 2, so that the mounting seat 12 can slide on the base 1 and the movable block 9, and the arc surface of the mounting seat 12 is used to squeeze the inclined surface of the clamping block 302, so that the clamping block 302 can avoid to one side, and at the same time, it can drive the first spring 307 to be compressed, so that the first spring 307 generates elastic force. When the clamping groove 305 is aligned with the clamping block 302, the first spring 307 releases the elastic force to drive the clamping block 302 into the clamping groove 305, thereby limiting the position of the mounting seat 12, and then the upper mold 13 and the lower mold 14 can be installed on the stamping forming device. Compared with the threaded connection method, this connection method is more convenient to disassemble and assemble, and takes less time, thereby improving the working efficiency of the stamping forming device.

[0031] A limiting groove 2 is provided on the top of the base 1 and the bottom of the moving block 9. The inner wall of the limiting groove 2 is slidably connected to the limiting block 11. One side of the limiting block 11 is connected to one side of the mounting seat 12. A plurality of placement grooves 15 are provided on the inner wall of the lower mold 14. The inner wall of the placement groove 15 is connected to a second spring 16, and the other ends of the plurality of second springs 16 are connected to the same pushing block 17. The outer wall of the pushing block 17 fits the inner wall of the lower mold 14. The cooling mechanism 4 includes two first fixed plates 404. One side of the first fixed plate 404 is connected to one side of the fixed block 7. One side of the first fixed plate 404 is connected to an airbag 405. The other side of the airbag 405 is connected to a second fixed plate 406. One side of the second fixed plate 406 is connected to one side of the moving block 9. One side of the airbag 405 is connected to a guide tube 402. The other end of the guide tube 402 passes through one side of the first fixed plate 404 and is connected to a nozzle 403. The outer wall of the guide tube 402 is connected to a support sleeve 401. One side of the support sleeve 401 is connected to one side of the fixed block 7.

[0032] The specific implementation method is as follows: When the stamping is completed, the air cylinder 5 drives the moving block 9 to move upward through the ejector rod. The upward movement of the moving block 9 drives the two second fixing plates 406 to move. The movement of the two second fixing plates 406 drives the two air bags 405 to be compressed, so that the air bags 405 can generate gas. The gas generated by the air bags 405 flows through the guiding pipe 402 to the nozzle 403 and is ejected from the nozzle 403, so that the rubber parts after stamping can be cooled. The gas ejected from the nozzle 403 shortens the time required for the rubber parts to be completely cooled, thereby improving the working efficiency of stamping. By arranging the nozzle 403 obliquely, the gas can be blown onto the rubber parts after stamping at a suitable angle, so that every part of the rubber parts can be blown, thereby improving the cooling effect of the gas. By arranging the pushing block 17 and the second spring 16, during the stamping process, the pushing block 17 will be squeezed by the rubber parts to drive the second spring 16 to be compressed, and the second spring 16 generates an upward elastic force. After the stamping is completed, the second spring 16 can drive the pushing block 17 to move upward through the elastic force, so that a part of the formed rubber parts can be pushed out of the lower die 14, thereby facilitating the removal of the rubber parts.

[0033] Working principle: When in use, the cylinder 5 is started, the push rod of the cylinder 5 moves downward to drive the moving block 9 to move downward, and the moving block 9 drives the upper mold 13 downward to contact the lower mold 14 through one of the mounting seats 12, so that the stamping operation can be performed. When the mold needs to be replaced, the connecting plate 303 is moved to drive the clamping block 302 to disengage from the clamping groove 305, so that the restriction on the mounting seat 12 can be released. At the same time, the clamping block 302 can drive the first spring 307 to compress and generate elastic force through the sliding sleeve 306, and then push The movable mounting seat 12 drives the limiting block 11 to separate from the limiting groove 2, so that the upper mold 13 and the lower mold 14 respectively connected to the two mounting seats 12 can be disassembled. At this time, the first spring 307 will drive the sliding sleeve 306 and the clamping block 302 to return to their original positions through elastic force. During installation, the limiting block 11 is inserted into the limiting groove 2, and the arc surface side of the mounting seat 12 is used to squeeze the inclined surface side of the clamping block 302, so that the clamping block 302 avoids to one side, and can drive the first spring 307 to compress and generate elastic force. When the clamping groove 305 is aligned with the clamping block 302, the first spring 307 releases its elastic force to drive the clamping block 302 to clamp with the clamping groove 305, so that the position of the mounting seat 12 can be restricted, and then the installation operation of the upper mold 13 and the lower mold 14 can be completed, and the replacement of the upper mold 13 and the lower mold 14 can be realized. When the stamping is completed, the cylinder 5 will drive the moving block 9 and the two second fixing plates 406 to move upward through the ejector rod, and the upward movement of the two second fixing plates 406 can drive the two airbags 40 5 is compressed to make the airbag 405 generate gas. The gas generated by the airbag 405 can flow to the nozzle 403 through the guide tube 402 and be ejected from the nozzle 403, so as to cool the rubber part after stamping. During the stamping process, the push block 17 will be squeezed by the rubber part to drive the second spring 16 to compress and generate elastic force. After the stamping is completed, the second spring 16 can drive the push block 17 to push a part of the formed rubber part out of the lower mold 14 through the elastic force, so as to facilitate the removal of the rubber part.
