A powder metallurgy mold pressing heating device

Abstract

The utility model provides a powder metallurgy mold pressing heating device, which belongs to the technical field of powder metallurgy; it comprises: a bottom plate and a cover plate; a square groove is provided at the bottom of the cover plate, a circular groove is provided on the inner wall of the square groove, and a spring is fixedly installed on the inner wall of the circular groove. The utility model aligns the square groove at the bottom of the cover plate with the fixing pin and inserts it. When the clamping block is squeezed by the fixing pin, the clamping block moves to the depth of the circular groove. When the fixing pin is fully inserted into the square groove, the clamping block loses the squeezing. At this time, the spring pushes the connecting block and the clamping block to move to the fixing pin and is clamped and fixed with the fixing pin. When the heating is finished, by pulling the pull rod, the connecting block and the clamping block are driven to move to the depth of the circular groove, so that the cover plate can be separated from the bottom plate, which is beneficial to improve the tightness of the connection between the bottom plate and the cover plate during heating, ensure the uniformity of heating, and facilitate the disassembly and assembly of the cover plate.

[0002] Powder metallurgy is a process technology that produces metal powder or uses metal powder (or a mixture of metal powder and non-metallic powder) as raw material, and manufactures metal materials, composite materials and various types of products through forming and sintering.

[0003] An existing powder metallurgy mold pressing and heating device can refer to the utility model patent with Chinese patent announcement number CN208450601U, which discloses a powder metallurgy mold pressing and heating device, including a metallurgical mold base plate and a heating block. A metallurgical mold frame is fixedly connected to the central position of the top plate wall of the metallurgical mold base plate, and a powder material cavity is provided inside the metallurgical mold frame. The side walls around the outside of the metallurgical mold frame are fixedly connected to limited heating blocks.

[0004] However, during the actual use of the device, it was found that although the device can limit the position of the heating block by limiting the heating block, thereby improving the density, strength and other parameters of the workpiece after molding, in the prior art, the base plate and the heating block are fixed by clamping, which makes it not firm enough when fixed. When heating the powder metallurgy mold, there will be problems of heat leakage, resulting in uneven heating. Therefore, the present application provides a powder metallurgy mold pressing heating device to meet the needs. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a powder metallurgy mold pressing heating device to solve the problem that the existing prior art is fixed by clamping a bottom plate and a heating pressing block, which makes the fixation not firm enough, and there is a problem of heat leakage when heating the powder metallurgy mold, resulting in uneven heating.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A powder metallurgy mold pressing heating device comprises: a base plate and a cover plate; a square groove is provided at the bottom of the cover plate, a circular groove is provided on the inner wall of the square groove, a spring is fixedly mounted on the inner wall of the circular groove, a connecting block is fixedly mounted on the end of the spring away from the circular groove, a clamping block is fixedly mounted on the side of the connecting block away from the spring, a fixing pin is clamped on the outer wall of the clamping block, the bottom of the fixing pin is fixedly connected to the top of the base plate, a through hole is provided on the outer wall of the cover plate, a pull rod is fixedly mounted on the outer wall of the connecting block, and the pull rod passes through the through hole.

[0009] A groove is provided on the top of the cover plate, and a handle is fixedly mounted on the inner wall of the groove.

[0010] The inner wall of the through hole is fixedly equipped with a folded cloth, and the side of the folded cloth away from the through hole is fixedly connected to the pull rod.

[0011] A sealing gasket is fixedly mounted on the top of the bottom plate, and the top of the sealing gasket abuts against the bottom of the cover plate.

[0012] The number of the springs, the connecting blocks, the clamping blocks and the fixing pins is four, and the four springs, the connecting blocks, the clamping blocks and the fixing pins are evenly distributed at the four corners of the top of the bottom plate.

[0013] Compared with the prior art, the utility model has at least the following beneficial effects:

[0014] 1. In the above scheme, the square groove at the bottom of the cover plate is aligned with the fixing pin and inserted. When the card block is squeezed by the fixing pin, the card block moves to the depth of the circular groove. When the fixing pin is fully inserted into the square groove, the card block is no longer squeezed. At this time, the spring pushes the connecting block and the card block to move toward the fixing pin and are clamped and fixed with the fixing pin. When the heating is finished, the cover plate can be separated from the bottom plate by pulling the pull rod to drive the connecting block and the card block to move to the depth of the circular groove.

[0032] like Figure 1 and Figure 3 As shown, a metallurgical frame 101 is fixedly assembled on the top of the base plate 1, a limit block 102 is fixedly assembled on the outer wall of the metallurgical frame 101, and a heat conducting rod 103 is fixedly assembled on the outer wall of the limit block 102; a metallurgical groove 201 is provided at the bottom of the cover plate 2, a limit groove 202 is provided on the outer wall of the cover plate 2, a heating rod 203 is fixedly assembled on the inner wall of the metallurgical groove 201, and a feed pipe 204 is fixedly connected to the inner wall of the cover plate 2. By putting the raw material into the metallurgical frame 101 through the feed pipe 204, and then connecting and fixing the cover plate 2 to the base plate 1, and then heating it through the heating rod 203 on the inner wall of the cover plate 2, it is beneficial to improve the heating effect of the powder metallurgy mold.

[0033] like Figure 1 As shown, a groove 10 is provided on the top of the cover plate 2, and a handle 11 is fixedly mounted on the inner wall of the groove 10.
