Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pressureless sintering, and particularly relates to a pressureless sintering die. Background Art
[0002] Pressureless sintering is a sintering method in which, under normal pressure (or vacuum), powder particles are bonded and densified through heating; existing sintering dies are usually placed horizontally in a sintering furnace. This method not only occupies a large amount of space inside the furnace, limits the number of sintered products, reduces the total number of molds loaded in one furnace, greatly reduces the sintering efficiency, increases the production cost, and has low production efficiency. Moreover, since the bottom of the die directly contacts the bottom of the sintering furnace, temperature differences at the furnace bottom will cause uneven heating of the materials at the bottom of the die, thereby affecting the quality of the entire sintered product. Therefore, a pressureless sintering die is needed. Summary of the Utility Model
[0003] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a pressureless sintering die, which can not only reduce the floor area of the die in the sintering furnace, increase the number of sintered products, but also make the materials inside the die evenly heated and improve the sintering efficiency.
[0004] The above technical purpose of the utility model is achieved through the following technical solutions: a pressureless sintering die includes a body. A rotating member is provided on each side of the body. The rotating member includes a turntable, and a cross bar is provided on the turntable. A U-shaped groove is provided on the surface of the body near the rotating member. A strip-shaped hole is opened in the U-shaped groove, and a handle is connected to the body through the strip-shaped hole.
[0005] In some embodiments, a concave surface portion is provided on the handle, and a plurality of the concave surface portions are arranged at intervals.
[0006] In some embodiments, a pull rod is rotatably connected to the turntable.
[0007] In some embodiments, the body includes two cover plates, two baffle plates and two moving plates. Convex blocks are provided at the ends of the two cover plates. The moving plates are connected to the cover plates through the convex blocks, and the cover plates are connected to the baffle plates through bolts.
[0008] In some embodiments, two cross bars are provided.
[0009] In some embodiments, the body is made of a high-strength wear-resistant material.
[0010] In summary, the utility model has the following beneficial effects:
[0011] The utility model sinterizes by vertically placing a mold into a sintering furnace, reducing the floor area of the mold in a limited space, thereby increasing the number of molds placed, improving the sintering output of products. At the same time, by the mutual restriction between the handle and the rotating part, not only can the mold be completely closed, improving the tightness of the mold and preventing material leakage, but also the direct contact between the bottom of the mold and the sintering furnace can be avoided, playing a certain spacing role, enabling the materials inside the mold to be heated completely evenly and improving the sintering efficiency.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0017] To make the purpose, technical solution and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the drawings. It should be understood that these descriptions are only exemplary and do not intend to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.
[0018] See Figure 1-2 Figure 1-2 , a pressureless sintering die, including a body 1, with a rotating member 5 provided on each side of the body 1. The rotating member 5 includes a turntable 51, and a cross bar 52 is provided on the turntable 51. A U-shaped groove 11 is provided on the surface of the body 1 near the rotating member 5, and a strip-shaped hole 12 is opened in the U-shaped groove 11. A handle 4 is connected to the body 1 through the strip-shaped hole 12. During sintering, after the operator places the material into the body 1, the operator pulls the handles 4 at both ends of the body 1, causing the two handles 4 to move away from each other. Taking one of them as an example, the handle 4 moves in the strip-shaped hole 12, causing a part of the handle 4 to extend beyond the end of the body 1. Subsequently, the operator rotates the turntable 51, causing the cross bar 52 on the turntable 51 to rotate into the gap between the handle 4 and the body 1, which not only serves to limit the reset of the handle 4 but also restricts the movement of the rotating member 5, strengthening the fixation of the body 1, that is, preventing the removal of the baffle 2, thereby ensuring the tightness of the internal material. Then, the operator places the body 1 in a vertical state into the sintering furnace, which can improve the occupancy rate of the internal space of the sintering furnace and increase the production volume of the product. The turntable 51 and the pulled-out handle 4 are at the same height, thus preventing the body 1 in the vertical state from tipping over in the sintering furnace and affecting the sintering of the internal material. Moreover, the turntable 51 and the handle 4 separate the material inside the body 1 from the inside of the sintering furnace by a certain distance, so that the material inside the body 1 is heated evenly, improving the sintering effect.
[0019] In some embodiments, a concave surface portion 41 is provided on the handle 4, and a plurality of concave surface portions 41 are arranged at intervals. The concave surface portion 41 can fit the finger positions of the operator when holding the handle 4, thereby enhancing the friction between the operator's hand and the handle 4, improving the operator's gripping strength, and ensuring that the die does not slip out of the hand during the handling of the die and damaging the sintered material inside the die.
[0020] In some embodiments, a pull rod 53 is rotatably connected to the turntable 51. The pull rod 53 can facilitate the operator to push the moving plate 3, thereby quickly pushing out the internally sintered material, and can also facilitate the operator to rotate the turntable 51, enhancing the operation efficiency, accelerating the filling and removal of the material, accelerating the sintering rate, and at the same time enabling the operator to more quickly turn the body 1 into a vertical state, facilitating the operation.
[0021] In some embodiments, the body 1 includes two cover plates 6, two baffle plates 2 and two moving plates 3. Bumps 13 are provided at the ends of the two cover plates 6. The moving plates 3 are connected to the cover plates 6 through the bumps 13, and the cover plates 6 are connected to the baffle plates 2 by bolts. During manufacturing, the operator only needs to place the two baffle plates 2 between the two cover plates 6 respectively, and then use bolts to fix the cover plates 6 and the baffle plates 2 together. Finally, insert the two moving plates 3 at both ends of the object formed by the two baffle plates 2 and the two cover plates 6 to seal it, and the manufacturing of the mold is completed. The operation is simple and fast, and the disassembly and assembly are convenient. When the molds are placed vertically for sintering, the molds will not interfere with or collide with each other, reducing the occupied position of the molds in the sintering furnace, increasing the number of molds sintered, and accelerating the sintering efficiency of the molds.
[0022] In some embodiments, two cross bars 52 are provided. With two cross bars 52 provided, when the operator places the handles 4 on the two cover plates 6 above the cross bars 52, two force points can be formed on the turntable 51 to achieve balance, preventing the turntable 51 from being lifted by the handle 4 due to a single force point, resulting in an imbalance in the internal pressure of the body 1 and affecting the sintering effect. Moreover, the two cross bars 52 can limit the two handles 4, thereby enhancing the limitation of the baffle plate 2 by the handle 4 and preventing the baffle plate 2 from being easily dropped or displaced due to external factors.
[0023] In some embodiments, the body 1 is made of a high-strength wear-resistant material. It can be a graphite material with high thermal conductivity, low cost and good processing performance, or an alloy steel with good thermal conductivity, resistance to thermal cracking, cracking, thermal wear and plastic deformation ability, but not limited thereto.
[0024] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
