AI Technical Summary
Existing molds suffer from problems such as low processing efficiency, insufficient positioning accuracy, and unstable forming quality in bushing processing. In particular, the raw materials are difficult to automatically detach from the mold during the stamping process, resulting in inaccurate positioning and poor product quality.
A bushing mold was designed, comprising a stamping unit and a shaping unit, which are connected by a conveying assembly. It adopts a stamping structure combining elastic elements and clearance rods, and combined with the arc groove of multiple cutters, to achieve automatic unloading and precise forming.
This improved processing efficiency, ensured the positioning accuracy and forming quality of the bushing, avoided manual intervention, and guaranteed the compatibility between the bushing and the instrument groove.

Abstract
Claims
1. A bushing mold assembled on a machining apparatus, characterized by: It includes a stamping unit and a shaping unit, which are connected by a conveying assembly; the stamping unit includes a fixed die and a moving die, and the shaping unit includes multiple forming tools, each of which is fixed to the tool holder of the processing equipment.
2. The bushing mold of claim 1, wherein: The fixed mold includes a lower template and a lower mold base stacked on top of each other. The lower template is provided with a first limiting groove and a first clearance groove. The lower mold base is provided with a second limiting groove corresponding to the first limiting groove and a second clearance groove corresponding to the first clearance groove.
3. The bushing mold of claim 2, wherein: An elastic element and a clearance rod are provided in the second clearance groove. The elastic element is connected to the clearance rod and drives it to move up and down in the first and second clearance grooves.
4. The bushing mold of claim 1, wherein: The moving mold includes a stacked upper mold base, an upper clamping plate, and a stripping plate. The upper mold base is connected to a displacement device of the processing equipment. The upper mold base is provided with a guide corresponding to the limiting groove and a stamping part corresponding to the first clearance groove.
5. The bushing mold of claim 4, wherein: The stripper plate is provided with guide limit holes corresponding to the guide and stamping limit holes corresponding to the stamping. The guide and stamping pass through the stripper plate and are exposed.
6. The bushing mold of claim 1, wherein: The shaping unit includes a first cutting tool, a second cutting tool, a third cutting tool, a fourth cutting tool, and a fifth cutting tool.
7. The bushing mold of claim 6, wherein: The first cutting tool is inclinedly mounted on the tool holder at the lower left of the processing equipment, and has a first arc-shaped groove at the top and a first clearance opening at the edge of the first arc-shaped groove.
8. The bushing mold of claim 6, wherein: The second cutting tool is located directly below the processing equipment. It has a second arc-shaped groove on its top and a second cutting head that is movably connected to its side through a recess. The cutting surface of the second cutting head corresponds to the cutting surface of the first cutting head located on the side of the conveying assembly near the shaping unit.
9. The bushing mold of claim 6, wherein: The third and fourth cutting tools are symmetrically and obliquely installed on the upper left and upper right tool holders of the processing equipment. Both of them are provided with arc-shaped grooves and clearance openings on their tops, namely the third arc-shaped groove and the third clearance opening, and the fourth arc-shaped groove and the fourth clearance opening, respectively.
10. The bushing mold of claim 6, wherein: The fifth cutting tool is mounted on the tool holder directly above the processing equipment, and has a semi-circular fifth arc groove on the top for stamping the stitching thread.
