[0019] A gear 22 is rotatably arranged inside the core block 16, and a frame plate 20 is arranged below the gear 22. The frame plate 20 is movably sleeved on the middle part of the gear 22, and a rack 21 is arranged on one end surface of the frame plate 20, and the rack 21 meshes with the gear 22. A first L-shaped bar 23 and a second L-shaped bar 24 are movably arranged above and below the end of the gear 22, respectively. The surfaces of the first L-shaped bar 23 and the second L-shaped bar 24 are both provided with rack surfaces that match the gear 22. Clamps 25 are fixedly installed on the tops of the two first L-shaped bars 23 and the tops of the two second L-shaped bars 24, and the two clamps 25 are symmetrically arranged on the tops of the core block 16. Since the first L-shaped bar 23 and the second L-shaped bar 24 are matched with the gear 22 through the rack surface, when the frame plate 20 is lifted, under the cooperation of the rack 21 and the gear 22, the gear 22 rotates forward, at this time, the first L-shaped bar 23 and the second L-shaped bar 24 are simultaneously displaced to the two sides of the core block 16, and the distance between the two clamps 25 increases. When the frame plate 20 descends, with the cooperation of the rack 21 and the gear 22, the gear 22 rotates reversely, at this time, the first L-shaped bar 23 and the second L-shaped bar 24 are simultaneously displaced to the center of the core block 16, and the distance between the two clamps 25 is reduced. A protrusion 29 is fixedly provided on the surface of the clamp 25, and a positioning block 27 is symmetrically installed on the bottom of the core 26. A groove 28 corresponding to the protrusion 29 is provided on the surface of the positioning block 27, and the protrusion 29 is fixedly installed in the groove 28. When the first L-shaped bar 23 and the second L-shaped bar 24 are simultaneously displaced to the center of the core block 16, the protrusion 29 can be snapped into the groove 28 to fix the core 26.

[0020] A strip 18 is fixedly installed at the bottom of the frame plate 20, and the end of the strip 18 protrudes from the lower mold 4. The bottom surface of the end of the strip 18 is set to an arc shape. A support plate 19 is installed in the middle of the strip 18, and a return spring is arranged between the support plate 19 and the core block 16. Lifting blocks 15 are symmetrically installed on the surface of the L-shaped workbench 1 and on both sides of the path groove 14. The lifting blocks 15 correspond to the ends of the strip 18. Through the ends of the strip 18 and the lifting blocks 15, when the lower mold 4 moves as a whole to the other end of the path groove 14, the arc surface of the lifting block 15 has a lifting effect on the strip 18. At this time, the strip 18 moves upward as a whole, and the frame plate 20 is also lifted. When the support plate 19 contacts the bottom of the core block 16, the strip 18 continues to move upward, and the support plate 19 can drive the core block 16 to move upward as a whole, which further facilitates the staff to replace the mold core 26.

[0021] Tension springs 17 are provided at the bottom of the core block 16 and on both sides of the long strip 18. When the lower mold 4 moves away from the lifting block 15, the position of the core block 16 is lowered under the action of the tension springs 17, so that the mold core 26 can be embedded in the interior of the lower mold 4, which has a good fixing effect on the mold core 26 and improves the quality of stamping the workpiece.

[0022] The displacement mechanism 39 includes a first cylinder 7, a movable block 8 is installed at the output end of the first cylinder 7, a first rotating block 9 is rotatably provided on the top of the movable block 8, a second rotating block 10 is rotatably provided on the top of the connecting plate 5, and a light rod 11 is connected between the first rotating block 9 and the second rotating block 10. Under the cooperation of the first rotating block 9, the second rotating block 10 and the light rod 11, when the first cylinder 7 drives the movable block 8 to move forward, the light rod 11 can pull the connecting plate 5 to make the connecting plate 5 move toward the other end of the path groove 14, so that the end of the long strip 18 can contact the lifting block 15 to lift the long strip 18. By setting the displacement mechanism 39 and the core block 16, the displacement mechanism 39 can drive the lower mold 4 to move freely along the path of the path groove 14, and through the cooperation between the internal structure of the core block 16 and the lifting block 15, the efficiency of the staff in replacing the mold core 26 can be greatly improved, and at the same time, the operating environment when replacing the mold core 26 is wider, thereby improving the convenience and comfort of operation.

[0023] A slide groove 12 is provided on the side surface of the L-shaped workbench 1, and a slider 13 corresponding to the slide groove 12 is provided on the surface of the movable block 8. The slider 13 is slidably installed in the slide groove 12. With the cooperation of the slider 13 and the slide groove 12, the stability of the movable block 8 during work can be effectively enhanced, and the operating efficiency of the device can be improved.

[0024] The guide mechanism 36 includes a storage cylinder 33, a storage groove 32 is provided inside the side plate 31, the storage cylinder 33 is movably installed inside the storage groove 32, a through groove 34 is provided on one side of the storage groove 32, a matching block 35 is fixedly provided on the surface of the storage cylinder 33, and the matching block 35 is movably installed in the through groove 34, a trapezoidal block 30 is fixedly provided at the front end of the lower mold 4, an inclined surface is provided on the upper surface of the trapezoidal block 30, a matching inclined surface is provided at the bottom of the matching block 35, the trapezoidal block 30 cooperates with the matching block 35, and the side of the upper mold 3 A guide rod 37 is provided, and the surface of the guide rod 37 is movably installed in the storage tube 33. When the lower mold 4 is located directly below the upper mold 3, the trapezoidal block 30 can be inserted into the through groove 34, and the inclined surface has an extrusion effect on the matching inclined surface, so that the position of the storage tube 33 is lifted upward, so that the bottom of the guide rod 37 can be inserted in the storage tube 33. When the upper mold 3 stamps the lower mold 4, the guide rod 37 and the storage tube 33 have a guiding effect on the upper mold 3 and the lower mold 4, thereby ensuring the stamping quality of the upper mold 3 and the lower mold 4.

[0025] The level of the lifting block 15 is lower than that of the polished rod 11 . When the displacement mechanism 39 is working, the polished rod 11 may swing. Since the level of the lifting block 15 is lower than that of the polished rod 11 , the lifting block 15 will not affect the swing of the polished rod 11 .

[0026] Working principle: First, when the first cylinder 7 drives the movable block 8 to move forward, the light rod 11 can pull the connecting plate 5 to move the connecting plate 5 to the other end of the path groove 14, so that the end of the long strip 18 can contact the lifting block 15, and then the arc surface of the lifting block 15 has a lifting effect on the long strip 18. At this time, the long strip 18 is displaced upward as a whole, and the frame plate 20 is also lifted. With the cooperation of the rack 21 and the gear 22, the gear 22 rotates forward. At this time, the first L-shaped strip 23 and the second L-shaped strip 24 are displaced to both sides of the core block 16 at the same time, and the distance between the two clamping plates 25 increases, and the protrusion 29 is disengaged from the groove 28. Then, when the support plate 19 contacts the bottom of the core block 16, the long strip 18 continues to move upward, and the support plate 19 can drive the core block 16 to move upward as a whole, and the mold core 26 is separated from the lower mold. Tool 4, so as to facilitate the staff to disassemble the core 26, the next step, the first cylinder 7 drives the movable block 8 to move backward, at this time, driven by the light rod 11, the lower mold 4 moves to the bottom of the upper mold 3, because the long strip 18 is away from the lifting block 15, under the action of the tension spring 17, the position of the core block 16 is lowered, and at the same time, under the action of the reset spring, the support plate 19 drives the frame plate 20 to move down, and under the cooperation of the rack 21 and the gear 22, the gear 22 rotates in the opposite direction. At this time, the first L-shaped strip 23 and the second L-shaped strip 24 are simultaneously displaced toward the center of the core block 16, and the spacing between the two clamping plates 25 is reduced. The protrusion 29 can be snapped into the groove 28 to fix the core 26, and the core 26 can be embedded in the lower mold 4 to ensure the stamping quality of the upper mold 3 and the lower mold 4.
