[0001] The utility model relates to the technical field of molds, in particular to a mold for high-temperature environments. Background Art

[0002] A forging die is a die used in the forging process, mainly for plastic deformation of raw materials under the action of external forces to obtain parts with the required shape and size:

[0003] Publication number "CN220259449U" discloses a high-temperature forging die, including a die base, a lower die and a stable stamping mechanism. The lower die is located at the upper end of the die base. The two sides of the die base are fixedly connected with support frames. A die groove is opened at the upper end of the lower die, and a quick demolding mechanism is positioned inside the die groove. The high-temperature forging die of the utility model can drive a first piston rod by a first air cylinder to drive a stamping plate and an upper die to stamp and shape the raw materials below. The guide rods are positioned at the four corners of the upper end of the die base and penetrate through the stamping plate and the stable frame at the upper end for positioning, strengthening the stability of the stamping plate when moving downward. When the raw materials are stamped and formed, a second piston rod can be driven by a second air cylinder to drive a demolding plate to eject the formed raw materials, which is very convenient and fast. Wear-resistant steel sheets reduce friction and at the same time reduce wear around the demolding plate;

[0004] The demolding plate in the above patent is supported by a second air cylinder, and the pressure borne by the raw materials during stamping will be transmitted to the demolding plate and the second air cylinder, resulting in the second air cylinder bearing a large pressure and increasing the probability of damage. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0018] Embodiment: As Figures 1-4 shown, the present utility model provides a mold for high-temperature environments, including a bottom plate 1. The top end of the bottom plate 1 is fixedly installed with a workbench 11. An empty groove 12 is opened at the top end of the bottom plate 1. A lower mold 13 is fixedly arranged in the empty groove 12. The top end of the workbench 11 is fixedly installed with a bracket 14. The top end of the bracket 14 is fixedly installed with a first hydraulic rod 15. The output end of the first hydraulic rod 15 penetrates the top of the bracket 14. The output end of the first hydraulic rod 15 is fixedly installed with a connecting plate 16. The bottom end of the connecting plate 16 is fixedly installed with an upper mold 17. The upper mold 17 and the lower mold 13 are used in cooperation. A load-bearing plate 18 is fixedly installed inside the workbench 11. A lifting plate 19 is placed on the top end of the load-bearing plate 18. Symmetrically distributed fixed blocks 191 are fixedly installed on the outer side of the lifting plate 19. Positioning rods 192 penetrate the top ends of both fixed blocks 191. A plurality of positioning rods 192 all penetrate the load-bearing plate 18. A lifting plate 193 is movably clamped on the top end of the load-bearing plate 18. The upper surface of the inner wall of the workbench 11 is fixedly installed with a second hydraulic rod 194. The output end of the second hydraulic rod 194 penetrates the load-bearing plate 18. The output end of the second hydraulic rod 194 is fixedly connected to the lifting plate 193.

[0019] At the top of the workbench 11, symmetrically distributed support plates 2 are fixedly installed. On the side of the support plates 2 close to the lower mold 13, symmetrically distributed fixing rods 21 are fixedly installed. A positioning plate 22 is movably sleeved on the outer sides of the two fixing rods 21. The positioning plate 22 is made of titanium alloy, reducing the probability of damage to the positioning plate 22. At the same time, the titanium alloy material is lighter, enabling the first spring 23 to smoothly push the positioning plate 22 to move. The positioning plate 22 and the support plate 2 are fixedly connected by two first springs 23.

[0020] At the bottom end of the positioning plate 22, symmetrically distributed clamping blocks 3 are integrally formed. On the top of the workbench 11, two groups of symmetrically distributed clamping grooves 31 are formed. The clamping blocks 3 are movably clamped in the clamping grooves 31. By providing the clamping blocks 3 and the clamping grooves 31, the stability of the positioning plate 22 during movement is improved, thereby better positioning the raw materials.

[0021] At the four corners of the bottom end of the load-bearing plate 18, stabilizing rods 4 are fixedly installed. The stabilizing rods 4 are fixedly connected to the lower surface of the inner wall of the workbench 11. By providing the stabilizing rods 4, the bearing capacity of the load-bearing plate 18 is increased, thereby improving its stability.

[0022] At the bottom of the positioning rod 192, a clamping ring 5 is fixedly provided. At the top of the clamping ring 5, a second spring 51 is fixedly installed. The other end of the second spring 51 is fixedly connected to the load-bearing plate 18. By providing the clamping ring 5 and the second spring 51, when the lifting plate 19 rises, it can drive the fixing block 191, the positioning rod 192, and the clamping ring 5 to rise, causing the clamping ring 5 to squeeze the second spring 51. When the lifting plate 193 descends, the lifting plate 19 loses the thrust. At this time, the second spring 51 releases its elastic force and drives the clamping ring 5, the positioning rod 192, the fixing block 191, and the lifting plate 19 to reset, facilitating the next use.

[0023] On the upper surface of the inner wall of the bracket 14, symmetrically distributed limiting rods 6 are fixedly installed. The limiting rods 6 penetrate through the connecting plate 16. By providing the limiting rods 6, the stability of the connecting plate 16 during movement is improved.

[0024] On the top of the load-bearing plate 18, a placement groove 7 is formed. The lifting plate 193 is movably clamped in the placement groove 7. By providing the placement groove 7, the lifting plate 19 can be in contact with the load-bearing plate 18, enabling the load-bearing plate 18 to share the pressure of the lifting plate 19.

[0025] Working principle: During actual use, place the raw material on the top of the lower die 13. Drive the first hydraulic rod 15 to drive the connecting plate 16 to descend. The connecting plate 16 drives the upper die 17 to descend until it enters the lower die 13. At the same time, the jacking plate 19 supports the raw material, thus realizing the stamping of the raw material. Drive the second hydraulic rod 194 so that its output end drives the lifting plate 193 to rise. The lifting plate 193 drives the jacking plate 19 to rise, thereby ejecting the stamped raw material from the lower die 13. Through the set bearing plate 18, the pressure borne by the jacking plate 19 during stamping can be transmitted to the jacking plate 19. By pulling the positioning plate 22 in the direction away from the lower die 13, the positioning plate 22 applies pressure to the first spring 23 and causes deformation. When the raw material is placed on the top of the lower die 13, stop applying the pulling force to the positioning plate 22, so that the first spring 23 releases its elastic force and drives the positioning plate 22 to move towards the lower die 13, thereby positioning the raw material.

[0026] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these modifications and variations.
