[0002] Rubber vulcanization is one of the most important links in the production process of rubber products. The rubber vulcanization temperature directly affects the rubber vulcanization speed and the quality of the products. After vulcanization, the rubber has excellent tensile strength, wear resistance, heat resistance, cold resistance, chemical stability and other characteristics, and is suitable for the production of various rubber products.

[0003] The rubber ring is a common sealing material that can isolate liquids and prevent liquid leakage. During the processing of the rubber ring, the staff will place the rubber strip in the mold, and heat the rubber strip after the mold is closed to make it vulcanized and formed. The Chinese patent with publication number CN211164898U discloses a vulcanizer that is easy to replace molds, relates to the technical field of rubber processing, and aims to solve the more cumbersome technical problems when replacing molds of vulcanizers. The key points of its technical solution are: it includes a machine base and an upper mold and a lower mold. The machine base is provided with a push plate for placing the lower mold, and two locking holes are provided on the push plate, and the two locking holes are respectively located on both sides of the upper mold; a mounting hole is penetrated through the side wall of the lower mold, and a mounting plate is inserted in the mounting hole, a magnet sheet is provided on the upper surface of the mounting plate, and a first adsorption iron sheet that is magnetically attracted to the magnet sheet is provided on the top wall of the mounting hole; locking blocks are respectively provided on the two lower end faces of the mounting plate, and each locking block is respectively inserted in the locking hole at the corresponding position.

[0004] To summarize, when replacing the mold, the above patent first selects a lower mold that matches the size of the workpiece, pushes it along the upper surface of the push plate to just below the upper mold, and then separates the mounting plate from the top wall of the mounting hole and moves downward, so that the locking blocks are respectively inserted into the locking holes, thereby achieving the installation and fixation of the lower mold. However, since the upper mold and the lower mold are installed independently, the above patent needs to disassemble and assemble the upper mold and the lower mold separately when disassembling and assembling the mold, which will make the disassembly and assembly of the upper mold and the lower mold more troublesome and the disassembly and assembly efficiency low, which will in turn affect the processing efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a rubber ring vulcanization mold to solve the problem raised in the above background technology that since the upper mold and the lower mold are installed independently, the upper mold and the lower mold need to be disassembled and assembled separately when disassembling the mold in the above patent, which will cause the disassembly and assembly of the upper mold and the lower mold to be more troublesome, the disassembly and assembly efficiency is low, and then the processing efficiency will be affected.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a rubber ring vulcanization mold, comprising a frame,

A clamping strip is fixed to the output end of the hydraulic cylinder. A slot is provided on the top of the upper die seat, and the clamping strip is located in the slot.

[0011] In the above technical scheme, the extension of the hydraulic cylinder will drive the clamping strip, the upper mold base and the upper mold to descend, so that the upper mold and the lower mold are closed, and the rubber strip can be heated to make it vulcanized and formed. During the descending process of the upper mold, it will simultaneously drive the vertical rod to move vertically on the lower mold base. When disassembling and assembling the lower mold base, the fixation of the lower mold base can be released by the fixing assembly, and then the support plate and the lower mold base can be driven to move laterally by the transverse movement assembly. At the same time, the lower mold base will drive the upper mold base to move laterally through the vertical rod. Compared with the comparative case, the lower mold base and the upper mold base can be disassembled at the same time, and the disassembly and assembly efficiency is high, which can shorten the disassembly and assembly time and improve the processing efficiency.

[0012] Preferably, a fixing block is fixed to the bottom of the vertical rod, and a spring 1 is sleeved below the vertical rod, and two ends of the spring 1 are respectively connected to the fixing block and the bottom of the lower mold base.

[0016] Preferably, limiting bolts are installed at both ends of the side of the lower die seat, and one end of the limiting bolt is in contact with the vertical rod.

[0017] In the above technical solution, after the lower die base and the upper die base are disassembled, the limit bolt can be rotated to lock the vertical rod, thereby reducing the tension borne by the spring 1 and increasing its service life.

[0018] Preferably, the transverse movement assembly includes a second screw rod, which is installed at one end of the interior of the rectangular groove, and a guide rod is fixed to the other end of the interior of the rectangular groove. A motor is fixed to the side of the frame, and the output end of the motor is connected to the second screw rod. The second screw rod and the guide rod respectively pass through the two ends of the support plate, and the second screw rod and the support plate are threadedly connected.

[0020] Preferably, a limiting rod is provided through the side of the upper die seat, and a pull ring is fixed to the end of the limiting rod away from the upper die seat, a second spring is sleeved on the limiting rod, and both ends of the second spring are respectively connected to the pull ring and the outer wall of the upper die seat.

[0021] In the above technical solution, after the fixing assembly releases the fixation of the lower die base, the pull ring can be pulled to drive the limit rod to move out of the slot to prevent the limit rod from blocking the card strip. Thereafter, when the lower die base and the upper die base move laterally, the card strip can be pulled out of the slot to separate the hydraulic cylinder from the upper die base.

[0022] Compared with the prior art, the utility model has the following beneficial effects: the rubber ring vulcanization mold,

When the lower die base is disassembled, the fixing assembly can be used to release the fixation of the lower die base, and then the lateral movement assembly can be used to drive the support plate and the lower die base to move horizontally. At the same time, the lower die base will drive the upper die base to move horizontally through the vertical rod. Compared with the comparative case, the lower die base and the upper die base can be disassembled at the same time, and the disassembly and assembly efficiency is high, thereby shortening the disassembly and assembly time and improving the processing efficiency;

[0024] (2) A spring 1 and a limit bolt are provided. Under the elastic force of the spring 1, the fixed block and the vertical rod can be moved upward. When the hydraulic cylinder is separated from the upper die seat, the upper die seat can be supported to prevent the upper die from hitting the lower die and causing damage.
