[0023] Embodiment 1

[0024] like Figure 1-4As shown, the utility model proposes a drawer-type universal mold with a limiting structure, comprising a base 1, an upper mold 9 and a lower mold 10. A servo motor 2 is fixedly installed on the right inner wall of the base 1, and a bidirectional screw rod 3 is fixedly connected to the output end of the servo motor 2. The left end of the bidirectional screw rod 3 is rotatably connected to the left wall of the base 1. The left and right inner walls of the base 1 are commonly fixedly connected with a slide rod 4. The peripheries of the bidirectional screw rod 3 and the slide rod 4 are commonly slidably connected with two moving blocks 5. The tops of the moving blocks 5 are fixedly connected with connecting blocks 6. A long notch 7 is provided on the top wall of the base 1. The connecting blocks 6 all penetrate the long notch 7 and are fixedly connected with a clamping block 8. Two sliding grooves are provided on the opposite sides of the clamping block 8. A slider 1 11 and a slider 2 12 are fixedly connected on both sides of the upper mold 9 and the lower mold 10, respectively, and the slider 1 11 and the slider 2 12 are matched with the sliding grooves provided on the clamping block 8. A fixing component is provided on the top of the clamping block 8 for limiting and fixing the slider 1 11 and the slider 2 12 in the sliding groove of the clamping block 8.

[0025] In this embodiment: the fixing assembly includes a circular groove 13 opened on the top of the clamping block 8, and a plurality of springs 14 are evenly fixedly connected to the bottom of the circular groove 13, and a circular ring plate 15 is fixedly connected to the top of the spring 14. Through this arrangement, when the circular ring plate 15 is pressed, the spring 14 will be deformed; the inner ring of the circular ring plate 15 is movably sleeved with a plug post 16, and the outer bottom of the plug post 16 is symmetrically fixedly connected with two clamping blocks 18. Through this arrangement, the plug post 16 can be in the inner ring of the circular ring plate 15. The circular groove 13 and the bottom of the sliding groove of the clamping block 8, as well as the slider 11 and the slider 2 12 are all provided with through holes. The through hole at the bottom of the sliding groove of the clamping block 8 is provided with a card slot on the periphery, and the card slot matches the card block 18. Through this arrangement, the plug post 16 can be inserted to the bottom of the through hole and then rotated to make the card block 18 engage with the card slot, thereby limiting and fixing the slider 11 and the slider 2 12 in the sliding groove of the clamping block 8, and then fixing the upper mold 9 and the lower mold 10.

[0026] Embodiment 2

[0027] like Figure 1-4As shown, the utility model proposes a drawer-type universal mold with a limiting structure. Compared with the first embodiment, the top of the plug post 16 is fixedly connected with a twist block 17, and the bottom of the twist block 17 abuts against the top of the circular ring plate 15. Through this arrangement, the plug post 16 can be pressed and rotated by the twist block 17. When it is necessary to release the fixation of the upper mold 9 and the lower mold 10, the twist block 17 is rotated to make the block 18 at the bottom of the outer periphery of the plug post 16 be pulled out of the slot. At the same time, the spring 14 loses the pressing force of the circular ring plate 15 and will rebound quickly, The plate 15 is lifted up, and the annular plate 15 lifts up the torsion block 17, so that the plug post 16 can be quickly pulled out of the through hole, so that the fixation of the upper mold 9 and the lower mold 10 can be released very quickly; the bottom of the upper mold 9 abuts against the top of the lower mold 10, and the bottom of the lower mold 10 abuts against the top of the base 1. Through this arrangement, plastic leakage is avoided; threaded holes and sliding holes are provided on the moving block 5, and they are matched with the bidirectional screw rod 3 and the sliding rod 4 respectively. Through this arrangement, the moving block 5 can slide more smoothly around the bidirectional screw rod 3 and the sliding rod 4.

[0028] Working principle: When using this device, first start the servo motor 2 to drive the bidirectional screw 3 to rotate on the inner wall of the base 1, thereby driving the two moving blocks 5 to move toward each other at the periphery of the bidirectional screw 3 and the slide bar 4 at the same time. The two moving blocks 5 respectively drive the two clamping blocks 8 to move toward each other through the top fixed connection blocks 6, and stop after adjusting the distance between the two clamping blocks 8 to a suitable position. Slide the slider 1 11 fixedly connected to both sides of the upper mold 9 and the slider 2 12 fixedly connected to both sides of the lower mold 10 are slid and inserted into the slide grooves provided on the two clamping blocks 8, so that the device can clamp molds of any size, increasing the adaptability of the device. When the upper mold 9 and the lower mold 10 are inserted After reaching between the two clamping blocks 8, insert the plug post 16 downward from the circular groove 13, and the plug post 16 passes through the through holes on the slider 11 and the slider 2 12 until the bottom end of the plug post 16 is inserted into the through hole opened at the bottom of the slide groove of the clamping block 8, and then rotate the twist block 17 to drive the block 18 at the bottom of the outer periphery of the plug post 16 to engage with the two side grooves of the through hole opened at the bottom of the slide groove of the clamping block 8, thereby fixing the slider 11 and the slider 2 12 in the slide groove of the clamping block 8, and then fixing the upper mold 9 and the lower mold 10. When it is necessary to replace the upper mold 9 or the slider 11, just rotate the twist block 17 in the opposite direction to release the engagement of the block 18 with the groove, and then the upper mold 9 or the lower mold 10 can be replaced.

[0029] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
