A movable frame 43 is slidably connected inside the lower mold 1. A toothed plate 44 is fixedly installed on the outside of the connecting block 42. A gear 45 meshes on the outside of the toothed plate 44. The gear 45 is rotatably connected inside the base 41. A rotating shaft 46 is fixedly installed on the outside of the gear 45. A sliding rod 47 is slidably connected to the surface of the rotating shaft 46. A moving block 48 is fixedly installed on the surface of the sliding rod 47. A moving rod 49 is fixedly installed on the top of the moving block 48. The moving rod 49 is fixedly installed on the outside of the movable frame 43. The four sides of the forming mold can be scraped by moving the movable frame 43.

[0029] Secondly, a pressure plate 410 is fixedly installed on the surface of the lower mold 1. The surface of the pressure plate 410 has holes 411, which allow the insertion rod 412 to pass through the pressure plate 410.

[0030] Furthermore, a rod 412 is fixedly installed on the top of the connecting block 42. The rod 412 passes through the lower mold 1. A limiting rod 413 is hinged to the surface of the rod 412. A fixing plate 414 is fixedly installed on the surface of the limiting rod 413. The limiting rod 412 can be restricted by the limiting rod 413 after it passes through the pressure plate 410.

[0031] Furthermore, a spiral spring 415 is fixedly installed on the outer side of the insertion rod 412. The spiral spring 415 is fixedly installed on the inner side of the limiting rod 413. The spiral spring 415 provided on the surface of the insertion rod 412 can achieve the effect of resetting when the limiting rod 413 is pressed by the pressure plate 410.

[0032] In this embodiment, by setting the movable component 4, after processing, when the upper mold 3 moves upward under the action of the hydraulic rod 2, it will pull the limiting rod 413, connecting block 42 and toothed plate 44 on the surface of the insert rod 412 upward through the pressure plate 410. When the toothed plate 44 moves upward, it will drive the gear 45 and the rotating shaft 46 to rotate. When the rotating shaft 46 rotates in the opposite direction, it will drive the sliding rod 47, moving block 48, moving rod 49 and movable frame 43 to move upward, thereby scraping the four sides of the processed mold body to prevent excess waste and burrs from remaining on the four sides after stamping, which will affect the appearance of the mold body and subsequent use, improve the surface quality of the mold body, make its four sides more regular and smooth, facilitate subsequent assembly, and also prevent the mold from sticking to the inner wall of the lower mold 1 after processing, which would cause damage to the mold body when demolding. Example 2

[0033] like Figures 5-6 As shown, the moving component 5 includes: an abutment shaft 51, which is slidably connected inside the lower mold 1 and passes through the base 41.

The abutting rod 56 is placed on top of connecting bar 52, and can be moved upward by moving the abutting rod 56 to push the bottom of the forming mold.

[0035] Finally, an arc-shaped groove 460 is provided on the surface of the rotating shaft 46. The sliding rod 47 can be driven to slide when the rotating shaft 46 rotates through the arc-shaped groove 460 on the surface of the rotating shaft 46. The cross-section of the moving rod 49 is L-shaped. The L-shaped moving rod 49 can be used to facilitate the connection between the moving rod 49 and the movable frame 43.

[0036] In this embodiment, through the setting of the moving assembly 5, the reverse rotation of the gear 45 will contact the pressing of the contact rod 56 to the connecting strip 52, so that the telescopic rod 53 resets under the action of the fixed spring 54, so that the contact shaft 51 is driven to move upwards and is in contact with the bottom end of the finished mold, and the forming mold is pushed to move upwards in the lower mold 1, so that the mold is prevented from being difficult to be self-disengaged due to the too-tight fit with the inner wall of the lower mold 1, the large friction and the like after the processing is completed, and the mold can be more easily separated from the lower mold 1 by moving the contact shaft 51 upwards, so that the time required for demolding is effectively reduced, the production rhythm of the entire stamping processing is improved, and the production efficiency is improved.

[0037] The stamping die of the automobile lower framework can move the upper die 3 downwards by starting the hydraulic rod 2, and the upper die 3 is moved to the inside of the lower die 1 to process when the upper die 3 moves downwards. The pressing plate 410 is also driven to move downwards when the upper die 3 moves, and the fixed plate 414 is first penetrated by the insertion rod 412 and is in contact with the top end of the fixed plate 414. When the fixed plate 414 is contacted, the connecting block 42 is driven to slide downwards, and the toothed plate 44 is driven to slide downwards when the connecting block 42 slides downwards. The rotation of the gear 45 is driven when the toothed plate 44 slides downwards, and the rotation of the shaft 46 is driven when the gear 45 rotates. The sliding rod 47 is in contact with the sliding rod 47 downwards through the arc-shaped slot 460 formed on the surface of the shaft 46, and the movable frame 43 is driven to move downwards by the moving block 48 and the moving rod 49 when the sliding rod 47 slides downwards. When the processing is completed, the upper die 3 is moved upwards under the action of the hydraulic rod 2, and the limiting rod 413 on the surface of the insertion rod 412 is pulled upwards by the pressing plate 410. The connecting block 42 and the toothed plate 44 are also driven to move upwards when the limiting rod 413 moves upwards, and the gear 45 and the shaft 46 are driven to rotate in the opposite direction when the toothed plate 44 moves upwards. The sliding rod 47, the moving block 48, the moving rod 49, and the movable frame 43 are driven to move upwards when the shaft 46 rotates in the opposite direction, so that the four edges of the processed mold body are scraped, and the appearance and subsequent use of the mold body are prevented from being affected by the residual waste and burrs on the four edges after stamping processing. The surface quality of the mold body is improved, the four edges are more regular and smooth, further assembly is facilitated, and the mold is prevented from being adhered to the inner wall of the lower die 1 after processing, so that the body of the mold is damaged when demolding.

[0038] When the gear 45 rotates, it also drives the rotating rod 55 fixed on the surface to rotate, when the rotating rod 55 rotates, it drives the abutting rod 56 to swing downward, when the abutting rod 56 swings downward, it abuts the top end of the connecting strip 52 and drives the connecting strip 52 to move downward, when the connecting strip 52 moves downward, it drives the telescopic rod 53 to contract, when the telescopic rod 53 contracts, it drives the abutting shaft 51 to move downward, when the processing is completed, the reverse rotation of the gear 45 contacts the abutting rod 56 to press the connecting strip 52, so that the telescopic rod 53 resets under the action of the fixed spring 54, so that it drives the abutting shaft 51 to move upward and abuts the bottom end of the processed mold, pushes the forming mold to move upward in the lower mold 1, prevents the mold from being difficult to be pulled out by itself after the processing is completed due to the too tight fit with the inner wall of the lower mold 1, the large friction force and other reasons, through the upward movement of the abutting shaft 51 abutting the bottom end of the processed mold and pushing it to move upward, the mold can be more easily separated from the lower mold 1, effectively reducing the time required for demolding, improving the production rhythm of the entire stamping processing, and improving the production efficiency.
