A nut processing mold

Abstract

This application discloses a nut processing mold, belonging to the field of mold processing technology. The nut processing mold includes a mold body with multiple grouting grooves on its upper surface and multiple movable plates below it. A pair of limiting grooves are formed inside the lower part of each grouting groove, and a connecting groove is formed inside the lower part of each limiting groove, penetrating the mold body. A top block is provided inside each limiting groove. Through a targeted demolding structure design, the problem of nut blanks getting stuck in the grouting grooves is efficiently solved, while also ensuring ease of operation. When the nut blank becomes difficult to remove due to adhesion to the inner wall of the grouting groove after cooling, the operator only needs to flip the mold so that the grouting groove faces downwards, and then press down on the movable plates. The movable plates will drive the movable rod to move downwards synchronously, causing the top block at the upper end of the movable rod to precisely act on the bottom of the nut blank in the grouting groove. The top block can push the nut blank out of the groove, making it convenient for the operator to remove.

[0018] The present application will be further described in detail below with reference to the accompanying drawings.

[0019] Reference Figures 1-4This application provides a nut processing mold, including a mold body 1. The upper end face of the mold body 1 is provided with a plurality of grouting grooves 8. During grouting, the plurality of grouting grooves 8 can be injected with molten raw materials at the same time, which can process a plurality of nut blanks at one time and improve processing efficiency. Multiple movable plates 9 are provided below the mold body 1. A support spring 10 is fixedly connected to the upper end of the movable plate 9, and the upper end of the support spring 10 is fixedly connected to the lower end of the mold body 1. A pair of limiting grooves 11 are provided in the lower part of the grouting groove 8. A connecting groove 12 is provided in the lower part of the limiting groove 11, and the connecting groove 12 penetrates the mold body 1. A top block 13 is provided inside the limiting groove 11. A movable rod 14 is fixedly connected to the lower end of the top block 13, and the movable rod 14 is located in the connecting groove 12. The lower end of the movable rod 14 is fixedly connected to the movable plate 9. When the nut blank is difficult to detach from the inner wall of the grouting groove 8 due to cooling, the operator only needs to flip the mold so that the grouting groove 8 faces downward, and then press down the movable plate 9. The movable plate 9 can drive the movable rod 14 to move down synchronously, so that the top block 13 at the upper end of the movable rod 14 can accurately act on the bottom of the nut blank in the grouting groove 8. The top block 13 can push the nut blank out of the groove for easy access by workers. At the same time, the support spring 10 under the moving plate 9 is naturally compressed when pressed and can automatically spring back after demolding, which drives the moving plate 9, the moving rod 14 and the top block 13 to quickly return to the initial position without the need for additional manual adjustment, simplifying the preparation steps after demolding.

[0020] A pair of fixing blocks 2 are fixedly connected to both sides of the outer wall of the mold body 1. A threaded rod 3 is fixedly connected to the upper end face of the fixing block 2. A fixing nut 15 is rotatably connected to the outer wall of the threaded rod 3 through the thread. A limit ring 4 is fixedly connected to the upper end face of the mold body 1. A pair of slots 5 are opened on both sides of the upper end face of the limit ring 4. A sealing cover plate 6 is provided above the mold body 1, and the sealing cover plate 6 is located inside the limit ring 4. A pair of extension blocks 7 are fixedly connected to both sides of the outer wall of the sealing cover plate 6, and the threaded rod 3 passes through the extension block 7. The sealing cover plate 6 is embedded in the limit ring 4 and the extension block 7 is inserted into the slot 5 to initially fix its position. Rotating the fixing nut 15 moves it down along the threaded rod 3 and close to the extension block 7, which can tightly press the sealing cover plate 6 onto the mold body 1, effectively preventing raw material leakage and ensuring molding quality.

[0021] Working principle: During preparation for processing, molten nut material is injected into multiple grouting grooves 8 until the grooves are completely filled, ensuring that the material fully fills every corner of the grooves. After grouting, the sealing cover plate 6 is placed above the mold body 1, aligning the extension blocks 7 on both sides of the outer wall of the sealing cover plate 6 with the threaded rods 3 on the fixing blocks 2 on the outer wall of the mold body 1, allowing the threaded rods 3 to pass through the extension blocks 7. Simultaneously, ensure that the sealing cover plate 6 is embedded in the limiting ring 4, and that the extension blocks 7 are engaged in the slots 5 on the upper end face of the limiting ring 4, initially fixing the position of the sealing cover plate 6. The fixing nut 15 on the outer wall of the threaded rod 3 is rotated, and through the threaded engagement, the fixing nut 15 moves downwards along the threaded rod 3 until the lower end face of the fixing nut 15 is tightly pressed against the upper end face of the extension block 7, tightly pressing the sealing cover plate 6 onto the mold body 1, completing the sealing assembly of the mold and preventing material leakage during subsequent grouting. Then, wait for the material to cool and solidify, forming a nut blank.

[0022] After the nut solidifies, remove the sealing cover plate 6. Rotate the fixing nut 15 in the opposite direction to move it upward along the threaded rod 3 and disengage it from the extension block 7. Then lift the sealing cover plate 6 upward to separate the extension block 7 from the threaded rod 3 and the sealing cover plate 6 from the limiting ring 4, exposing the nuts in the multiple grouting grooves 8 on the upper end face of the mold body 1.

[0023] During demolding, some nuts may get stuck in the grouting groove 8. Flip the mold body 1 so that the grouting groove 8 is facing down, press down on the moving plate 9, the moving plate 9 compresses the support spring 10, and at the same time drives the fixedly connected moving rod 14 to move down along the connecting groove 12. The top block 13 at the upper end of the moving rod 14 moves down accordingly, and the top block 13 contacts the nut blank that has cooled and formed in the grouting groove 8 and pushes it out of the grouting groove 8.

[0024] Collect the ejected nut blank to complete one nut processing cycle; if further processing is required, repeat the above operations, and perform grouting, cooling and demolding again.

[0025] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
