Technical Field

[0001] This utility model relates to the field of metal forming technology, and more specifically, it relates to a screw mold that is easy to disassemble. Background Technology

[0002] In metal forming technology, screw dies are key equipment for manufacturing fasteners such as screws.

[0003] Traditional screw mold designs typically fix the mold body directly inside the workbench, forming a whole with the workbench through welding, riveting, or other non-removable connection methods.

[0004] For example, the welding screw forming mold disclosed in application publication number CN102601234A includes an upper mold, a lower mold, and a product ejector pin disposed in the lower mold. The upper mold has an upper mold core with a screw head forming cavity at the bottom. The lower mold has a lower mold core with a screw shank forming cavity inside. The bottom of the screw shank forming cavity is a conical cavity. The end face of the lower mold core has an annular groove with a V-shaped cross-section.

[0005] In the above, the screw rod forming cavity is fixed inside the lower mold core, and the screw rod forming cavity and the lower mold core are not detachable. When the screw rod forming cavity is worn or damaged due to long-term use, the entire lower mold core needs to be disassembled and repaired, which increases the difficulty and cost of maintenance. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a screw mold that is easy to disassemble, convenient to maintain, and reduces costs.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An easy-to-disassemble screw mold, including a mounting plate,

[0009] The mounting plate is equipped with a lower mold component, which is detachably connected to the mounting plate.

[0010] The mounting plate has a storage slot for the lower mold component to extend into. The lower mold component connects to the inner wall of the storage slot. The lower mold component includes a connecting tube and two snap-fit ​​plates, which are symmetrically distributed and hinged to the outer wall of the connecting tube.

[0011] So that the connecting pipe can be placed in the storage slot, and the bottom surfaces of the two snap-fit ​​plates can be connected to the mold frame.

[0012] Both snap-fit ​​plates are equipped with movable plates. One side of the movable plate is hinged to the snap-fit ​​plate, and the opposite side is connected to the mounting plate. The mounting plate has several connection holes. Both snap-fit ​​plates have several plug-in blocks on their bottom surfaces. The plug-in blocks are elastic and extend into the connection holes to connect with them.

[0013] The present invention is further configured such that: a positioning groove is provided on the mounting plate, and a guide strip is provided on the movable plate, which is placed in the positioning groove. The guide strip is elastic and is connected to the positioning groove.

[0014] The present invention is further configured such that: a slot is formed on the outer wall of the connecting pipe, and a protrusion is provided on the inner wall of the storage groove, the protrusion being elastic and connected to the slot.

[0015] The present invention is further configured such that: a first adjustment groove is provided on one side of the snap-fit ​​plate and a second adjustment groove is provided on the other side; a first rotating rod is provided in the first adjustment groove and both ends of the first rotating rod are connected to the first adjustment groove; a first sleeve rod is provided on the movable plate and extends into the first adjustment groove; the first sleeve rod is sleeved on the first rotating rod and rotatably connected to the first rotating rod.

[0016] The present invention is further configured such that: a second rotating rod is provided in the second adjusting groove, both ends of the second rotating rod are connected to the second adjusting groove, and a second sleeve rod is provided on the connecting pipe that extends into the second adjusting groove, and the second sleeve rod is sleeved on the second rotating rod and rotatably connected to the second rotating rod.

[0017] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0018] Rotate the plate outwards, and the positioning groove will snap out of the guide bar. At the same time, the movable plate will rotate around the first rotating rod, causing the movable plate to separate from the mounting plate. Then, pry the snap-fit ​​plate outwards, and the plug-in block will snap out of the connecting hole. At the same time, the snap-fit ​​plate will rotate around the second rotating rod, causing the snap-fit ​​plate to separate from the mounting plate. Finally, pull the connecting tube upwards from the storage slot. The protrusion on the inner wall of the storage slot will snap off from the connecting tube slot, thus completely removing the lower mold part from the mounting plate. When the screw rod is used for molding, the lower mold part may wear or be damaged due to long-term use. Simply remove the lower mold part from the mounting plate to facilitate maintenance and reduce costs. Attached Figure Description

A storage groove 5 is provided on the mounting plate 1 so that the lower mold 2 can extend into the storage groove 5. The lower mold 2 is connected to the inner wall of the storage groove 5.

[0026] The lower mold part 2 includes a connecting pipe 3 and two snap-fit ​​plates 4. The two snap-fit ​​plates 4 are symmetrically distributed and are hinged to the outer wall of the connecting pipe 3, so that the connecting pipe 3 is placed in the storage groove 5. The bottom surface of the two snap-fit ​​plates 4 is connected to the mold frame, and the inner wall of the connecting pipe 3 is threaded.

[0027] A slot 11 is provided on the outer wall of the connecting pipe 3, and a protrusion 12 is installed in the slot 11 on the inner wall of the storage groove 5. The protrusion 12 is elastic and engages with the slot 11. When the connecting pipe 3 is fixed in the storage groove 5, the protrusion 12 engages in the slot 11. When the connecting pipe 3 is pulled out from the storage groove 5, the protrusion 12 is pulled out from the slot 11.

[0028] The snap-fit ​​plate 4 has a first adjustment groove on one side and a second adjustment groove on the other side. A second rotating rod 15 is installed in the second adjustment groove. Both ends of the second rotating rod 15 are connected to the second adjustment groove. A second sleeve rod 16 is installed on the connecting pipe 3 and extends into the second adjustment groove. The second sleeve rod 16 is sleeved on the second rotating rod 15 and rotates with the second rotating rod 15. When the second sleeve rod 16 rotates around the second rotating rod 15, the snap-fit ​​plate 4 rotates around the connecting pipe 3.

[0029] Movable plates 6 are installed on both snap-fit ​​plates 4. One side of the movable plate 6 is hinged to the snap-fit ​​plate 4, and the other side is connected to the mounting plate 1. A first rotating rod 13 is installed in the first adjustment groove. Both ends of the first rotating rod 13 are connected to the first adjustment groove.

The movable plate 6 has a plate that can apply force to the movable plate 6, making it easier to move the movable plate 6.

[0031] Working principle: Rotate the plate outward, and the positioning groove 9 will be disengaged from the guide bar 10. At the same time, the movable plate 6 will rotate around the first rotating rod 13, causing the movable plate 6 to separate from the mounting plate 1. Both movable plates 6 on the snap-fit ​​plate 4 will separate from the mounting plate 1. Then, pry the snap-fit ​​plate 4 outward, and the plug block 8 will be disengaged from the connecting hole 7. At the same time, the snap-fit ​​plate 4 will rotate around the second rotating rod 15, causing the snap-fit ​​plate 4 to separate from the mounting plate 1. Finally, pull the connecting tube 3 upward from the storage groove 5. The protrusion 12 on the inner wall of the storage groove 5 will be disengaged from the slot 11 of the connecting tube 3, so that the lower mold part 2 can be completely removed from the mounting plate 1. When the screw rod is used for a long time during the molding process, the lower mold part 2 will wear or be damaged. Simply remove the lower mold part 2 from the mounting plate 1 to facilitate maintenance and reduce costs.

[0032] After maintenance, when the lower mold 2 needs to be installed on the mounting plate 1, first place the connecting pipe 3 into the storage groove 5, the protrusion 12 engages in the slot 11, the snap-fit ​​plate 4 rotates around the connecting pipe 3, and the plug-in block 8 on the two snap-fit ​​plates 4 engages and fixes with the connecting hole 7. Finally, the movable plate 6 rotates around the snap-fit ​​plate 4, and the guide strip 10 on the movable plate 6 engages and fixes in the positioning groove 9. By installing the snap-fit ​​plate 4 and the movable plate 6 on the connecting pipe 3, the snap-fit ​​plate 4 and the movable plate 6 fix the mounting plate 1 on both sides at once, improving the stability of the lower mold 2 and the mounting plate 1.
