Description

Technical Field

[0001] This utility model relates to the field of conveyor belt technology, specifically a synchronous vulcanization mold for rubber conveyor belts. Background Technology

[0002] Rubber conveyor belts are used in transportation across numerous industries. Different industries have different strength requirements for conveyor belts. For example, industries like coal mining and metallurgy handle large volumes of transport and require specialized high-strength conveyor belts. These belts often incorporate high-strength structures such as steel cables and fiber fabrics, and may even require bonding separate, high-strength upper and lower sheets to form a single conveyor belt to ensure overall strength. Vulcanization is a crucial step in the processing of rubber conveyor belts. Traditional vulcanization equipment typically processes the upper and lower sheets separately, requiring separate adjustments to molds and processing conditions, resulting in low efficiency. Therefore, how to reduce or even eliminate the need for separate adjustments to molds and processing conditions for the upper and lower sheets during the vulcanization process to improve efficiency has become an increasingly urgent problem for relevant technical personnel. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a synchronous vulcanization mold for rubber conveyor belts.

[0004] A synchronous vulcanizing mold for rubber conveyor belts includes an upper mold, a middle mold, and a lower mold. The upper mold, middle mold, and lower mold are arranged horizontally from top to bottom. The middle mold includes a first middle mold and a second middle mold. There are two sets of first middle molds, symmetrically arranged at both ends of the second middle mold. The lower part of the upper mold has an upper punch hole, the upper part of the middle mold has an upper pin, the lower part of the middle mold has a lower punch hole, and the upper part of the lower mold has a lower pin. The positions of the upper punch hole, upper pin, lower punch hole, and lower pin correspond one-to-one.

[0005] Furthermore, the lower middle part of the upper mold and the middle mold are both concave, while the upper part of the middle mold and the lower mold are both horizontal.

[0006] Furthermore, upper pads are symmetrically arranged on both sides of the upper part of the middle mold, and lower pads are symmetrically arranged on both sides of the upper part of the lower mold.

[0007] Furthermore, the first middle mold is symmetrically provided with a first upper flow groove, the second middle mold is symmetrically provided with a second upper flow groove, and the lower mold is symmetrically provided with a lower flow groove. The direction of the first and second upper flow grooves is parallel to the long side of the lower mold, and the direction of the lower flow groove is perpendicular to the long side of the lower mold.

[0008] Furthermore, the upper part of the lower mold is symmetrically provided with baffles, the direction of the baffles is parallel to the long side of the lower mold, and the baffles intersect with the inner end of the lower flow groove.

[0009] Furthermore, positioning grooves are symmetrically arranged in the middle of the first and second intermediate molds, and positioning holes are symmetrically arranged on both sides of the positioning grooves. A large positioning post is fixedly arranged on the upper part of the lower mold at the position corresponding to the positioning groove, and a small positioning post is fixedly arranged on the upper part of the lower mold at the position corresponding to the positioning hole. When the intermediate mold and the lower mold are closed, the large positioning post is inserted into the positioning groove, and the small positioning post is inserted into the positioning hole.

[0010] Furthermore, mold-lifting grooves are provided at positions corresponding to the junctions of the first and second intermediate molds on both sides of the lower part of the upper mold and the upper part of the lower mold.

[0011] Furthermore, handles are symmetrically fixed on both sides of the first and second intermediate molds.

[0012] The beneficial effects of this utility model of a synchronous vulcanizing mold for rubber conveyor belts are as follows:

[0013] 1. The upper mold, middle mold, and lower mold provide a good structural foundation, allowing workers to simply place the lower piece on the upper part of the lower mold and the upper piece on the upper part of the middle mold, and then feed the lower mold, lower piece, middle mold, and upper piece as a whole into the vulcanizing equipment and move the upper mold down to close the mold. This allows for simultaneous vulcanization of the upper and lower pieces, effectively reducing or even avoiding the need to adjust the molds and processing conditions of the upper and lower pieces separately as required by traditional vulcanizing equipment, thereby effectively improving efficiency.

[0014] 2. The fit between the large positioning pin and the positioning groove, and the fit between the small positioning pin and the positioning hole, effectively ensures the accuracy of the middle mold as an intermediate transition structure. The fit between the first upper flow groove, the second upper flow groove, and the lower flow groove effectively ensures the smooth discharge of excess rubber during vulcanization. The baffle effectively prevents excess rubber from flowing back, thereby effectively ensuring the processing quality.

[0015] 3. The upper and lower backing plates allow workers to adjust the distance between the upper mold and the middle mold, and between the middle mold and the lower mold, according to the required thickness of the upper and lower pieces, effectively meeting the processing needs of upper and lower pieces with different thicknesses.

[0016] 4. The mold release groove and handle effectively ensure the convenience of mold opening. Attached Figure Description

The positions of the upper punch 11, upper punch 10, lower punch 9, and lower punch 6 correspond one-to-one.

[0026] Furthermore, the lower middle part of the upper mold 1 and the middle mold 2 are both concave, while the upper part of the middle mold 2 and the lower mold 4 are both horizontal.

[0027] Furthermore, upper pads 8 are symmetrically arranged on both sides of the upper part of the middle mold 2, and lower pads 5 are symmetrically arranged on both sides of the upper part of the lower mold 4.

[0028] Furthermore, the first middle mold 18 is symmetrically provided with a first upper flow groove 21 on its upper part, the second middle mold 19 is symmetrically provided with a second upper flow groove 20 on its upper part, and the lower mold 4 is symmetrically provided with a lower flow groove 14 on its upper part. The direction of the first upper flow groove 21 and the second upper flow groove 20 is parallel to the long side of the lower mold 4, and the direction of the lower flow groove 14 is perpendicular to the long side of the lower mold 4.

[0029] Furthermore, the lower mold 4 is symmetrically provided with baffles 12 on its upper part. The direction of the baffles 12 is parallel to the long side of the lower mold 4, and the baffles 12 intersect with the inner end of the lower glue groove 14.

[0030] Furthermore, positioning grooves 16 are symmetrically arranged in the middle of the first intermediate mold 18 and the second intermediate mold 19, and positioning holes 17 are symmetrically arranged on both sides of the positioning grooves 16. A large positioning post 7 is fixedly arranged on the upper part of the lower mold 4 at the position corresponding to the positioning groove 16, and a small positioning post 3 is fixedly arranged on the upper part of the lower mold 4 at the position corresponding to the positioning hole 17. When the intermediate mold 2 and the lower mold 4 are closed, the large positioning post 7 is inserted into the positioning groove 16, and the small positioning post 3 is inserted into the positioning hole 17.

[0031] Furthermore, mold-lifting grooves 13 are provided at the positions corresponding to the junctions of the upper mold 1 and the lower mold 4 on both sides and the first middle mold 18 and the second middle mold 19.

[0033] The working principle of this utility model for a synchronous vulcanizing mold for rubber conveyor belts is as follows: In the initial state, the lower mold 4 is located outside the vulcanizing equipment. The upper pad 8, which meets the processing requirements, is fixed to the upper part of the middle mold 2, and the lower pad 5 is fixed to the upper part of the lower mold 4. The lower sheet to be vulcanized is placed flat in the middle position of the upper part of the lower mold 4, and the middle mold 2 is placed flat on the upper part of the lower sheet, so that the positioning groove 16 corresponds to the large positioning post 7 and the positioning hole 17 is located directly above the small positioning post 3. The lower mold 4, lower sheet, middle mold 2, and upper sheet are fed into the vulcanizing equipment as a whole, and the upper mold 1 is moved down until the mold is closed. At this time, the large positioning post 7 is inserted into the positioning groove 16, and the small positioning post 3 is inserted into the positioning hole 17, and then the vulcanizing equipment can be vulcanized. Simultaneously, the upper and lower pieces are vulcanized. During vulcanization, the lower punch 6 is inserted into the lower punch hole 9, and the upper punch 10 is inserted into the upper punch hole 11. Excess rubber material at the lower piece position flows out through the lower flow groove 14, and excess rubber material at the upper piece position flows out through the first upper flow groove 21 and the second upper flow groove 20. After vulcanization is completed, the upper mold 1 is separated from the upper piece through the mold release grooves 13 on both sides of the upper mold 1, and the upper mold 1 is moved up and reset. After the lower mold 4, lower piece, middle mold 2, and upper piece are moved out as a whole, the upper piece is removed. The middle mold 2 is separated from the lower piece through the mold release grooves 13 on both sides of the lower mold 4. By holding the handle 15, the middle mold 2 is removed, and then the lower piece is removed, thus completing a complete vulcanization process.
