The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0019] The utility model provides a lathe clamp for mold production, and its structure is as follows Figures 1 to 3As shown, it includes a support frame 1, which has two sections of slide grooves 2 and is provided with two side plates 3, a bearing 4 is fixed to the inner bottom surface and is provided with a driving mechanism, the inner sides of the two side plates 3 are fixed with a carrying plate 8 through two connecting rods 7, and the bottom ends are fixed with sliders 29 slidably connected to the slide grooves 2, the side of the carrying plate 8 has two straight grooves 9 and is provided with a clamping mechanism, the bottom ends of the two sliders 29 are fixed with a first column 10, the side of the first column 10 is movably connected to the first round tube 11, the bearing 4 is connected to the shaft 5, the other end of the shaft 5 is fixed with a turntable 6, the top edge of the turntable 6 is fixed with two second columns 12, the sides of the two second columns 12 are movably connected to the second round tubes 13, and the two second round tubes 13 are respectively fixedly connected to the two first round tubes 11 through driving rods 14. By using the lathe clamp for mold production, the position of the clamping mechanism is adjusted by driving one end of the two driving rods 14 through the turntable 6 so that the other ends of the two driving rods 14 drive the side plates 3 to move inward through the slider 29, so that the operator can adjust the position of the clamping mechanism without disassembly, ensuring that the user is more convenient to use.

[0020] Specifically, the driving mechanism includes a hydraulic cylinder 16 and a first gear 15. The first gear 15 is fixed to the side of the rotating shaft 5. The hydraulic cylinder 16 is fixed to the inner bottom surface of the support frame 1 through a support seat 17 and its piston rod is connected to a moving rod 18. A plurality of first racks 19 meshing with the moving rod 18 are fixed to the side of the moving rod 18 close to the first gear 15. The moving rod 18 is driven by the piston rod of the hydraulic cylinder 16 to move so that the plurality of first racks 19 mesh with the first gear 15. At this time, the rotating shaft 5 drives the turntable 6 and one end of the two driving rods 14 to rotate. Finally, the other ends of the two driving rods 14 drive the side plate 3 to move inward through the slider 29 to adjust the position of the clamping mechanism so as to adapt to molds of different specifications.

[0021] Specifically, the clamping mechanism includes two clamping plates 20 and a driving motor 24, and sliding rods 21 are fixed on the two clamping plates 20. The two sliding rods 21 are slidably connected to the straight slot 9 and an L-shaped rod 22 is fixed at the other end thereof, and a plurality of second racks 23 are fixed on the inner sides of the two L-shaped rods 22. The output end of the driving motor 24 is connected to a second gear 26 that meshes with the second rack 23 for transmission. The second gear 26 is driven to rotate by the output end of the driving motor 24 so that it meshes with the second racks 23 on the two L-shaped rods 22 for transmission. Finally, the two L-shaped rods 22 drive the clamping plates 20 to move inward through the sliding rod 21 to fix and tighten the two ends of the mold to avoid displacement during the processing and thus affecting the processing effect.

[0022] Furthermore, the two L-shaped rods 22 are relatively arranged on the side of the second gear 26 to facilitate the meshing transmission between the second gear 26 and the second rack 23 and to enable relative movement, thereby achieving the clamping effect of the clamping block 20.

[0023] Furthermore, two round rods 27 are fixed to the inner sides of the two clamping plates 20, and a clamping block 28 is fixed to the other end of the round rod 27. By performing two-point clamping, the clamping is tightened and the effect is better.

[0024] Furthermore, the driving motor 24 and the two connecting rods 7 are fixed by a connecting block 25 for fixing the driving motor 24 .

[0025] The working principle of the utility model is as follows: first, the mold is placed between the two supporting plates 8, and then the hydraulic cylinder 16 is started, and its piston rod drives the moving rod 18 to move so that a plurality of first racks 19 are meshed with the first gear 15 for transmission. At this time, the rotating shaft 5 drives the turntable 6 and one end of the two driving rods 14 to rotate, and the other ends of the two driving rods 14 drive the side plates 3 to move inward through the sliders 29 to adjust the positions of the two supporting plates 8 so that both ends of the mold are located between the two clamping plates 20; then the two driving motors 24 are started, and the output ends of the two driving motors 24 drive the second gear 26 to rotate so that they are meshed with the second racks 23 on the two L-shaped rods 22 for transmission. Finally, the two L-shaped rods 22 drive the clamping plates 20 to move inward through the sliding rods 21 to fix and tighten the mold through a plurality of clamping blocks 28, so as to facilitate the smooth progress of subsequent processing work.

[0026] The whole process is simple and convenient to operate, and a plurality of clamping blocks 20 can be easily adjusted to a suitable position so as to be suitable for the clamping requirements of the current mold.

[0027] The above description is only a description of the preferred embodiment of the utility model, and is not any limitation on the scope of the utility model. Any changes and modifications made by ordinary technicians in the field of the utility model based on the above disclosure shall fall within the scope of protection of the claims.
