[0027] like Figure 1-Figure 7As shown, an injection mold for efficiently producing a rope saw includes an upper mold 1, a middle plate 2, a lower mold 3, and a beading cavity 5. The beading cavity 5 is arranged on the lower mold 3 and the lower side of the middle plate 2, which means that the structures of the lower mold 3 and the middle plate 2 are both provided with the beading cavity 5. The middle plate 2 is provided with a gate sleeve 4, a main channel 21, a branch channel 22, and a middle plate gate 23. The gate sleeve 4, the main channel 21, the branch channel 22, the middle plate gate 23 and the beading cavity 5 are mutually connected after the injection mold is closed. The material body is injected from the gate sleeve 4 and enters the branch channel 22 along the main channel 21. The material body on the branch channel 22 then enters the complete beading cavity formed by the combination of the middle plate 2 and the lower mold 3 through the middle plate gate 23, and then a TPU wrapping structure is formed in the corresponding structure of the product structure. The middle plate gate 23 is a cavity structure in the middle plate 2, which can be flexibly set so that the branch channel 22 is connected with the beading cavity 5. At least two beading cavities 5 are provided, and the middle plate 2 is provided with the same number of beading cavities 5 as that on the lower mold 3, which are used to place beads. That is, the beading cavities 5 on the middle plate 2 and the beading cavities 5 on the lower mold 3 are combined to form a complete cavity structure for placing beads. The middle plate gate 23 can connect the cavities at two positions to each other by providing a flow port 6, and can indirectly control the flow speed of the material by changing the size of the cavity, and indirectly control the flow direction of the material by changing the path of the cavity.

[0028] Furthermore, a plurality of beading positions are set on a beading cavity 5. If the injection mold is used to prepare a rope saw with equal diameter, the specifications of the beading positions set on the beading cavity 5 are all the same; if the injection mold is used to prepare a rope saw with unequal warp, the specifications of the beading positions set on the beading cavity 5 can be set according to the requirements and the corresponding setting rules.

[0029] Furthermore, the specifications of the beading positions are the same or different, and the corresponding beading positions can be set according to the required beading position sizes.

[0030] Furthermore, a positioning column 121 is provided on the upper mold 1, and a plurality of positioning holes are provided on the middle plate 2 and the lower mold 3. The positioning column 121 passes through the positioning hole 24 on the middle plate 2 and the positioning hole on the lower mold 3 in sequence, so that the upper mold 1, the middle plate 2, and the lower mold 3 are tightly fitted in sequence.

[0031] Furthermore, the upper mold 1 includes a top plate 11 and a covering portion 12 . The top plate 11 and the covering portion 12 have different widths, and the top plate 11 and the covering portion 12 are combined to form a T-shaped structure.

[0032] Furthermore, the lower mold 3 is a T-shaped structure.

[0033] Furthermore, the sprue bushing 4 is located at the side end of the middle plate 2 .

[0034] Furthermore, a plurality of main flow channels 21 are provided, and all of them are connected with the branch flow channel 22 , and different main flow channels 21 flow to different positions of the branch flow channel 22 .

[0035] Furthermore, four positioning posts 121 and four positioning holes 24 are provided.

[0036] Furthermore, the positioning columns 121 are installed and locked at the four corner points of the upper mold 1 , the positioning holes on the middle plate 2 are arranged at the four corner points of the middle plate 2 , and the positioning holes of the lower mold 3 are arranged at the four corner points of the lower mold 3 .

[0037] The injection mold for efficiently producing rope saws in the utility model, when in use, follows the principle: injection molding of TPU → middle plate gate sleeve → middle plate main flow channel → middle plate branch flow channel → transfer to the lower model cavity; the method of use is: before preparation, the beads are placed on the beading position on the beading cavity 5 in the lower mold 3, the rope body (such as: wire rope) connecting the beads passes through several beads in sequence, and then the upper mold 1, the middle plate 2, and the lower mold 3 are covered together and locked firmly, and finally injection molding is started to ensure the molding effect of the prepared product.

[0038] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
