Description

Technical Field

[0001] This utility model relates to the field of cold heading mold technology, and in particular to a high-efficiency cold heading mold for thin plate nuts. Background Technology

[0002] Cold heading dies are a type of process equipment used for cold heading of metal. By applying pressure or impact to the metal through the die, plastic deformation is caused, thereby obtaining a metal part of the required shape and size. Among them, the cold heading die for thin plate nuts is a type of cold heading die specifically used for producing thin plate nuts.

[0003] In existing technology, thin plate nuts are difficult to detach from the mold quickly after molding. This not only prolongs the production cycle, but may also cause scratches or deformation on the product surface, affecting the appearance quality and dimensional accuracy of the product. In addition, the difficulty in demolding will increase the wear of the mold, reduce the service life of the mold, and thus increase the production cost. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology does not have a structure for quick demolding of the formed thin plate nuts, which not only prolongs the production cycle of the nuts, but may also cause scratches or deformation on the surface of the product. To this end, we propose an efficient cold heading mold for thin plate nuts.

[0005] To achieve the above objectives, this application adopts the following technical solution: a high-efficiency cold heading mold for thin plate nuts, comprising a housing, a mold body installed at one end of the housing, a push rod slidably connected to the inner wall of the mold body, a pull handle fixedly connected to one end of the push rod, and a top block fixedly connected to the other end of the pull handle.

[0006] Preferably, a limiting groove is provided on both sides of the inner wall of the housing, and a slider is slidably connected to the inner wall of the limiting groove. One side of the slider is fixedly connected to one end of the push rod surface.

[0007] Preferably, a spring is fixedly connected to one side of the inner wall of the push rod, and the other end of the spring is fixedly connected to one side of the inner wall of the housing.

[0008] Preferably, the inner wall of the mold body is provided with a sliding groove at all four ends, a baffle is slidably connected to the inner wall of the sliding groove, and a force-bearing block is fixedly connected to one side of the baffle.

[0009] Preferably, a protective pad is installed on one side of the baffle.

[0010] Preferably, the top block is made of rubber.

[0011] Preferably, the surface of the mold body has a plurality of ventilation holes.

[0012] Technical effects and advantages of this utility model: In this invention, the user pushes the sliders on both sides outward along the inner wall of the limiting groove. After the nut inside the mold body is formed, the user pulls the handle backward, causing the push rod to compress the spring. At this time, the user releases the handle, causing the top block at one end of the push rod to impact the force block, which pushes the formed nut inside the mold body outward, moving the push rod out of the mold body. The push rod drives the top block to impact the formed thin plate nut inside the mold body, causing it to quickly detach from the mold body. This effectively avoids quality problems such as product deformation or surface scratches that may be caused by manual removal, reduces the time spent on manual operation during demolding, and significantly improves the overall processing efficiency of the mold.

[0015] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0016] Reference Figure 1 - Figure 5As shown, this utility model provides a technical solution: a high-efficiency cold heading mold for thin plate nuts, including a shell 1, a mold body 2 installed at one end of the shell 1, a push rod 3 slidably connected to the inner wall of the mold body 2, a pull handle 4 fixedly connected to one end of the push rod 3, a top block 5 fixedly connected to the other end of the pull handle 4, a limiting groove 6 opened on both sides of the inner wall of the shell 1, a slider 7 slidably connected to the inner wall of the limiting groove 6, a side of the slider 7 fixedly connected to one end of the surface of the push rod 3, a spring 8 fixedly connected to one side of the inner wall of the push rod 3, the other end of the spring 8 fixedly connected to one side of the inner wall of the shell 1, a sliding groove 9 opened at all four ends of the inner wall of the mold body 2, a baffle 10 slidably connected to the inner wall of the sliding groove 9, a force-bearing block 11 fixedly connected to one side of the baffle 10, a protective pad 12 installed on one side of the baffle 10, the top block 5 is made of rubber, and a plurality of vent holes 13 are opened on the surface of the mold body 2; Specifically: When the user prepares to process the raw material, the raw material is first loaded into the mold body 2 through the feeding device, and then the raw material inside the mold body 2 is stamped into shape by the stamping machine. The air vents 13 on the surface of the mold body 2 can be used to timely discharge the air and small debris generated during the stamping process, avoiding the problem of bulging or uneven surface of the nut after forming due to residual gas. The protective pads 12 on the surface of the baffle 10 can buffer the impact force on the mold body 2 during stamping. At this time, the raw material being stamped inside the mold body 2 squeezes the baffle 10, causing the baffle 10 to squeeze the top block 5 through the force block 11. The top block 5 pushes the push rod 3 outward along the inner wall of the limiting groove 6 through the sliders 7 on both sides. After the nut inside the mold body 2 is formed, the user pulls the handle 4 backward, causing the push rod 3 to compress the spring 8, which in turn compresses the spring 8. At this point, the user releases the handle 4, causing the spring 8 to release and rebound, pulling the push rod 3. This causes the top block 5 at one end of the push rod 3 to impact the force block 11, which in turn pushes the formed nut inside the mold body 2 outward, moving the push rod 3 out of the mold body 2. The push rod 3 drives the top block 5 to impact the formed thin plate nut inside the mold body 2, causing it to quickly detach from the mold body 2. This effectively avoids quality problems such as product deformation or surface scratches that may be caused by manual removal, reduces the time spent on manual operation during demolding, and significantly improves the overall processing efficiency of the mold.

[0017] Working Principle: When the user prepares to process the raw material, the raw material is first loaded into the mold body 2 through the feeding device, and then the raw material inside the mold body 2 is stamped and formed by the stamping machine. During the stamping process, the vent holes 13 on the surface of the mold body 2 can timely discharge the generated air and small debris, effectively avoiding the problem of bulging or uneven surface of the nut after forming due to gas residue. At the same time, the protective pads 12 on the surface of the baffle 10 can buffer the impact force on the mold body 2 during stamping. When the raw material inside the mold body 2 is stamped, the raw material will squeeze the baffle 10, causing the baffle 10 to squeeze the top block 5 through the force block 11, which in turn causes the top block 5 to push the push rod 3, and move outward along the inner wall of the limiting groove 6 through the sliders 7 on both sides. After the nut is formed, the user pulls the pull handle 4 backward, causing the push rod 3 to squeeze the spring 8, allowing the spring 8 to store and compress. Subsequently, the user releases the pull handle 4, the spring 8 releases its rebound force, and pulls the push rod 3, causing the top block 5 at one end of the push rod 3 to strike the force block 11. The force block 11 then pushes the formed nut outward from inside the mold body 2. Finally, the push rod 3 drives the top block 5 to strike the formed thin plate nut, causing it to quickly detach from the inside of the mold body 2.

[0018] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
