[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3 This utility model provides an embodiment of a split-type fastener trimming assembly mold, including a base plate 1, which serves as the basic support component of the mold and is installed on the press workbench, providing a stable installation reference for the entire mold system. A guide post 2 is fixedly connected to the upper part of the base plate 1, cooperating with a sliding sleeve 3 to form a guiding mechanism. This ensures the linear accuracy of the upper mold 6 when the top plate 4 moves up and down, avoiding trimming errors caused by mold closing misalignment. A sliding sleeve 3 is slidably connected to the outer side of the guide post 2, lubricated with grease. The sliding cooperation guides the up and down movement of the top plate 4 while reducing friction. The sliding sleeve 3 is fixedly connected to the top plate 4, which is connected to the moving end of the press and transmits the stamping power to the upper mounting plate 5 and the upper die 6. At the same time, the sliding sleeve 3 and the guide column 2 maintain the motion accuracy. The lower part of the top plate 4 and the upper part of the bottom plate 1 are both fixedly connected to the mounting plates 5, which are divided into upper and lower groups and fixed on the top plate 4 and the bottom plate 1 respectively. They are used to install the upper die 6 and the lower die 7. The mold can be quickly disassembled and assembled by the disassembly component 8. The upper die 6 is set at the lower part of the upper mounting plate 5, and the cutting edge punch is set at the lower part. It cooperates with the lower die 7 to complete the fastener cutting process.

[0032] Reference Figures 1-3The lower set of mounting plates 5 has a lower mold 7 inserted into its lower part and a concave die cutting edge set on its upper part to accommodate fastener blanks and provide a cutting edge positioning reference. It forms a shearing pair with the upper mold 6. The inner wall of the mounting plate 5 is provided with a disassembly component 8. The disassembly component 8 includes a mounting groove 81 opened on the opposite side of the two sets of mounting plates 5, which cooperates with the slider 82 to provide a sliding mounting track for the upper mold 6 and the lower mold 7, and is limited by the insertion rod 84. The slider 82 is inserted into the inner wall of the mounting groove 81. After being inserted into the mounting groove 81, it can slide along the groove to realize the installation and disassembly of the upper mold 6 and the lower mold 7. The slider 82 is fixedly connected to the upper part of the upper mold 6. The slider 82 has a slot 83 that is horizontally opened through it. The right side of the slot 83 is set as an inclined surface for the insertion of the insertion rod 84. The inclined surface design on the right side can guide the insertion rod 84 to be inserted quickly and reduce friction.

[0033] Reference Figures 1-3 A rod 84 is inserted into the inner wall of the upper mold 6 and the inner wall of the slot 83 on the right side, locking the slider 82 in the mounting groove 81 to prevent the upper mold 6 and the lower mold 7 from loosening during stamping. An operating component 85 is rotatably connected to the inner wall of the right side of the rod 84. The rear side of the rod 84 is L-shaped, and the front side of the rod 84 is cylindrical. The rod 84 and the operating component 85 are elastically connected by a torsion spring 86. One end is fixedly connected to the inner wall of the connecting rod 84, and the other end is fixedly connected to the operating component 85 to provide elastic restoring force. When the operating component 85 rotates, the torsion spring 86 pushes the rod 84 to maintain the engagement with the slot 87 to prevent loosening. A slot 87 is opened on the right side of the mounting plate 5. The left side of the operating component 85 is engaged with the inner wall of the slot 87. The left side of the operating component 85 is L-shaped, and it can be inserted into the inner wall of the slot 87 by rotating 90 degrees. The right side of the operating component 85 is T-shaped, which is convenient for finger rotation.

[0034] Reference Figures 2-4 An auxiliary component 9 is provided on the right side of the insertion rod 84. The auxiliary component 9 includes a sleeve 91. The left side of the sleeve 91 is fixedly connected to the right side of the insertion rod 84. The right side of the sleeve 91 has evenly spaced notches, which engage with the fitting groove 93 of the operating member 85 through limiting protrusions 92, enhancing the locking stability of the operating member 85 after rotation. The notches give the sleeve 91 elasticity, which can adaptively adjust the tightness of the engagement. Multiple sets of limiting protrusions 92 are fixedly connected to the inner side of the sleeve 91. The limiting protrusions 92 are hemispherical. The hemispherical limiting protrusions 92 engage with the fitting groove 93 of the operating member 85 to prevent the operating member 85 from rotating on its own during stamping vibration, ensuring that the insertion rod 84 is always in a locked state. Multiple sets of fitting grooves 93 are evenly spaced on the outer side of the operating member 85. The outer side of the limiting protrusions 92 engages with the inner wall of the fitting grooves 93, providing multiple locking positions to facilitate the stable fixation of the operating member 85 at different angles.

[0035] Working principle: During use, the mold is fixed to the press worktable via the base plate 1, and the top plate 4 is connected to the movable end of the press. The press drives the opening and closing of the upper and lower molds. The upper mold 6 and lower mold 7 are respectively installed on the upper and lower mounting plates 5 via the disassembly assembly 8. The sliding engagement of the slider 82 and the mounting groove 81, as well as the locking of the insertion rod 84, ensures stable positioning during operation. During the trimming process, the upper mold 6 moves downward with the top plate 4, forming a shearing pair with the lower mold 7 to complete the trimming process of the fastener blank.

[0036] When it is necessary to disassemble the upper mold 6 and the lower mold 7, manually rotate the T-shaped structure on the right side of the operating component 85 to overcome the elastic force of the torsion spring 86, causing the L-shaped structure on the left side of the operating component 85 to disengage from the slot 87. At the same time, the insert rod 84 is pulled out from the slot 83, releasing the limit on the slider 82. Simultaneously, when the operating component 85 rotates, the limiting protrusion 92 on the sleeve 91 disengages from the fitting groove 93 of the operating component 85, and slides the upper mold 6 along the mounting groove 81 to separate it from the mounting plate 5, completing the disassembly. Repeat the operation to disassemble the lower mold 7.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
