[0024] In order to solve the problems of long cycle and low efficiency in tire mold processing in the prior art, the present invention provides a tire mold split multi-head wire cutting machine.

[0025] like Figures 1 to 3 A tire mold splitting multi-head wire cutting machine shown in the figure includes a machine base 10 and a plurality of cutting mechanisms 20. The machine base 10 has an inner guide rail 11 and an outer guide rail 12 in the shape of a ring. The outer guide rail 12 is located at the inner circle of the inner guide rail 11, and a workpiece 40 is installed at the inner guide rail 11. Each cutting mechanism 20 is arranged on the outer guide rail 12 along the circumferential movement of the outer guide rail 12. The cutting mechanism 20 includes a moving part 21 and a cutting part 22. The cutting part 22 is connected to the moving part 21. The moving part 21 drives the cutting part 22 to rotate circumferentially on the outer guide rail 12. At least a part of the moving part 21 can move radially relative to the outer guide rail 12, and drives the cutting part 22 to move radially along the outer guide rail 12, approaching or moving away from the workpiece 40 on the inner guide rail 11, so as to split the workpiece 40.

[0026] In this embodiment, an inner guide rail 11 and an outer guide rail 12 are arranged on a machine base 10, wherein the inner guide rail 11 is used to install a workpiece 40 such as a tire mold raw material in a fixed annular shape, and a cutting mechanism 20 is installed on the outer guide rail 12, and a plurality of cutting mechanisms 20 are arranged. In this way, when cutting the workpiece 40, the workpiece 40 is installed on the inner guide rail 11, and the position of the workpiece 40 is adjusted by aligning the workpiece 40, and then the position of each cutting mechanism 20 on the outer guide rail 12 is adjusted, so that each cutting mechanism 20 is respectively facing a position on the workpiece 40 that needs to be cut, and the moving part 21 of the cutting mechanism 20 drives the cutting part 22 to move toward the direction close to the workpiece 40, and the cutting part 22 of each cutting mechanism 20 cuts the workpiece 40, thereby achieving the effect of multi-head cutting of the workpiece 40. The above arrangement can cut a whole circle of workpiece 40 into multiple pieces at one time, reducing the number of cutting times, reducing the cutting cycle, and greatly improving the processing efficiency. For example, when the workpiece 40 needs to be cut into 8 pieces, it only needs to adjust the cutting mechanism 20 twice to complete the cutting. In addition, the overall structure is simple, and only a few cutting mechanisms 20 are needed to complete the cutting, reducing the investment cost.

[0027] like Figure 1 As shown, the base 10 of this embodiment includes an outer base 13 and an inner base 14, the outer base 13 is annular, the inner base 14 is disc-shaped, and the inner base 14 is arranged inside the outer base 13. Among them, the inner guide rail 11 is arranged on the inner base 14, and the outer guide rail 12 is arranged on the outer base 13. The outer base 13 and the inner base 14 can be arranged separately or integrated as needed. The outer base 13 and the inner base 14 of this embodiment are arranged separately to facilitate processing, assembly and other operations.

[0028] like Figure 2 As shown, the inner seat 14 includes a base 141, a turntable 142, a workbench 143 and a locking fixture 144. The turntable 142 is arranged on the base 141, and the workbench 143 is rotatably arranged on the turntable 142. The turntable 142 has an inner guide rail 11, so that the workbench 143 can be rotated relative to the base 141, thereby realizing the adjustment of the workpiece 40 on the workbench 143; the locking fixture 144 is arranged at the outer edge of the workbench 143, and the present embodiment is provided with a plurality of locking fixtures 144, each locking fixture 144 is arranged at the edge along the circumference of the workbench 143, thereby forming a ring shape matching the shape of the workpiece 40. When in use, the position state of the workpiece 40 is adjusted, and then the locking fixtures 144 work together to fix and lock the workpiece 40 on the machine base 10, thereby realizing the fixation of the workpiece 40. Of course, the specific number and setting method of the locking fixture 144 can also be adjusted as needed.

[0029] like Figure 3As shown, the moving part 21 comprises a first moving member 211, a second moving member 212 and a driving motor 213. The first moving member 211 and the second moving member 212 of the present embodiment are both plate-shaped members. Of course, the first moving member 211 and the second moving member 212 of other structural forms can also be adopted. The first moving member 211 is arranged on the outer guide rail 12, and can move circumferentially along the outer guide rail 12, thereby realizing that the cutting mechanism 20 as a whole moves on the outer guide rail 12 to adjust the position of the cutting mechanism 20. The present embodiment is provided with a linear guide 214 on the first moving member 211, and the second moving member 212 is movably arranged on the linear guide rail 214, and the second moving member 212 moves relative to the first moving member 211 along the linear guide rail 214. Since the cutting part 22 is arranged on the second moving member 212, the cutting part 22 follows the second moving member 212 to move synchronously. The driving motor 213 is disposed on the second moving member 212 , and is used to drive the second moving member 212 to move on the linear guide rail 214 , so that the cutting portion 22 can move close to or away from the workpiece 40 , thereby achieving cutting of the workpiece 40 .

[0030] Preferably, the linear guide rail 214 of the present embodiment extends radially along the outer guide rail 12. Thus, by driving the second movable member 212 to move along the linear guide rail 214, the second movable member 212 can be moved closer to or farther away from the workpiece 40 radially along the outer guide rail 12, thereby making the cutting portion 22 closer to or farther away from the workpiece 40, thereby enabling the cutting portion 22 to cut the workpiece 40.

[0031] In this embodiment, the cutting part 22 includes a wire rolling barrel 221, a column 222, an upper wire guide rail 223 and a lower wire guide rail 224. The wire rolling barrel 221 is wound with a cutting wire for cutting the workpiece 40. The wire rolling barrel 221 can be set on the driving motor 213 or on the second movable member 212; the column 222 is erected on the movable part of the moving part 21, that is, it is erected on the second movable member 212, and the column 222 is used to install and fix the upper wire guide rail 223 and the lower wire guide rail 224. The upper wire guide rail 223 is connected to the column 222 and is arranged horizontally. The cutting wire is passed through the upper wire guide rail 223. Similarly, the lower wire guide rail 224 is connected to the column 222 and is arranged horizontally. The lower wire guide rail 224 is located below the upper wire guide rail 223, and there is a certain distance between the two. The cutting wire passed through the upper wire guide rail 223 extends downward and is passed through the lower wire guide rail 224. Since there is a gap between the upper wire guide rail 223 and the lower wire guide rail 224, a cutting wire with one end suspended is formed between the upper wire guide rail 223 and the lower wire guide rail 224. This part of the cutting wire is used to cut the workpiece 40. More specifically, as the cutting portion 22 approaches the workpiece 40 driven by the second moving member 212, the cutting wire between the upper wire guide rail 223 and the lower wire guide rail 224 can perform wire cutting on the workpiece 40. Multiple cutting portions 22 cooperate together to achieve petal multi-head wire cutting of the annular workpiece 40.

[0032] Optionally, the upper wire guide rail 223 and the lower wire guide rail 224 are movably connected to the column 222, so as to facilitate the adjustment of the positions of the upper wire guide rail 223 and the lower wire guide rail 224 on the column 222, so as to meet different processing requirements. The lower wire guide rail 224 of this embodiment is fixedly arranged, and the upper wire guide rail 223 is movably arranged, so that the distance between the two can be adjusted by only adjusting the position of the upper wire guide rail 223.

[0033] Preferably, the upper wire guide rail 223 and the lower wire guide rail 224 of this embodiment are arranged in parallel, and the length direction of the two is along the radial direction of the outer guide rail 12, that is, the upper wire guide rail 223, the lower wire guide rail 224, and the linear guide rail 214 of the same cutting portion 22 have the same extension direction and all extend along the radial direction of the outer guide rail 12. Of course, the specific extension direction of the above-mentioned parts can also be adjusted accordingly as needed.

[0034] In this embodiment, the end of the upper wire guide rail 223 away from the workpiece 40 is the upper inlet end, the end of the upper wire guide rail 223 close to the workpiece 40 is the upper outlet end, and the end of the lower wire guide rail 224 close to the workpiece 40 is the lower inlet end. After the cutting wire is extended from the wire rolling barrel 221, it passes through the upper wire guide rail 223 through the upper inlet end in turn, and passes through the upper wire guide rail 223 from the upper outlet end and extends downward, and then passes through the lower wire guide rail 224 from the lower inlet end. It can pass through the lower outlet end of the lower wire guide rail 224 away from the workpiece 40, or it can be fixed in the lower wire guide rail 224. In this way, the cutting wire that cuts the workpiece 40 is relatively close to the workpiece 40, ensuring the cutting effect of the cutting wire on the workpiece 40, while avoiding interference between the workpiece 40 and other components of the cutting part 22.

[0035] like Figure 1 As shown, the tire mold split multi-head wire cutting machine also includes a plurality of locking switches 30, which are arranged at the outer guide rail 12 and located on the side of the cutting mechanism 20. The locking switch 30 is used to fix and lock the position of the cutting mechanism 20, so as to lock and fix the cutting mechanism 20 at a predetermined position of the outer guide rail 12. When in use, the workpiece 40 is first installed and adjusted in position, and then the position of the cutting mechanism 20 is adjusted so that the cutting wire on the cutting mechanism 20 is aligned and calibrated to the position on the workpiece 40 that needs to be cut, and then the locking switch 30 is locked to lock the position of the cutting mechanism 20. Multiple cutting mechanisms 20 perform the above process in sequence until all cutting mechanisms 20 are calibrated and fixed, and the driving motor 213 of each cutting mechanism 20 is controlled to drive the second moving member 212 and the cutting portion 22 thereon to approach the workpiece 40, so as to realize the split multi-head wire cutting of the workpiece 40.

[0036] Preferably, a plurality of locking switches 30 are provided, and in this embodiment, locking switches 30 are provided on opposite sides of each cutting mechanism 20, thereby restricting the cutting mechanism 20 in both directions on the outer guide rail 12 to ensure the stable and reliable position of the cutting mechanism 20.

[0037] It should be noted that, the multiple in the above embodiments refers to at least two.
