Detailed implementation mode

[0022] The utility model relates to a device for removing burrs of rubber sealing rings. Through the combined use of a first cylinder and a second cylinder, the automatic movement of the upper mold and the side plate is realized, the need for manual intervention is reduced, and the work efficiency is improved; the turntable and the sub-gear drive the cutter to rotate by using the rotational force, and cooperate with the cutter to cut the burrs of the rubber sealing ring. The following is a specific description of the solution through specific embodiments.

[0023] Refer to Figures 1 - 5 As shown in the figure, a device for removing burrs of rubber sealing rings includes:

[0024] A workbench 1, a lower mold 4 arranged above the workbench 1, and a support plate 2 arranged above the lower mold 4 and mounted on the workbench 1. A first cylinder 22, a second cylinder 21 and a side plate 221 are arranged on the support plate 2. An upper mold 3 is arranged at one end of the side plate 221 close to the lower mold 4; the lower mold 4 is slidably matched with the workbench 1, and a moving cylinder 11 is arranged at the sliding matching position; the support plate 2 is connected to the workbench 1 through a stud, and the moving cylinder 11 drives the lower mold 4 to slide on the workbench 1; the output end of the first cylinder 22 is threadedly connected to the side plate 221, the side plate 221 is slidably matched with the support plate 2, the output end of the second cylinder 21 is movably connected to the upper mold 3, and the upper mold 3 is movably connected to the side plate 221.

[0025] The lower mold 4 is provided with a lower sealing seat 43. A groove is further formed in the lower sealing seat 43, and an air hole 431 is further formed in the groove. The lower sealing seat 43 has the same structure as the upper sealing seat. The lower sealing seat 43 is threadedly connected to the lower mold 4. The turntable 42 passes through the lower mold 4, and the lower mold 4 is provided with a first motor connected to the turntable 42; the turntable 42 placed in the lower sealing seat 43 and mounted on the lower mold 4, a sub-gear 44 sleeved outside the lower sealing seat 43, the sub-gear 44 is rotationally matched with the lower sealing seat 43, and the main gear 41 is provided with a second motor mounted on the upper mold 3; the lower mold 4 is provided with a main gear 41 meshing with the sub-gear 44. Pillars 421 are provided on one side of the turntable 42 and the sub-gear 44 close to the lower sealing seat 43. The pillars 421 are threadedly connected to both the sub-gear 44 and the turntable 42, and a plurality of screw holes are formed in the turntable 42 and the sub-gear 44 at the threaded connection; a cutter 422 is provided on the pillar 421. The cutter 422 is a hot cutter 422. The cutter 422 is located at the mating part of the upper mold 3 and the lower mold 4. A positioning pin is further provided at the mating part of the upper mold 3 and the lower mold 4. The upper mold 3 is provided with an upper sealing seat mating with the lower sealing seat 43.

[0026] Working principle: First, all components of the device are reset to ensure that the first cylinder 22 and the second cylinder 21 are in the initial positions, and the lower mold 4 and the upper mold 3 are separated to facilitate placing the rubber sealing ring. Then, the rubber sealing ring to be processed is placed in the groove of the lower sealing seat 43 to ensure its correct alignment. The first cylinder 22 pushes the side plate 221, and the second cylinder 21 moves following the first cylinder 22, thereby driving the upper mold 3 to descend until the upper sealing seat of the upper mold 3 is in close contact with the lower sealing seat 43 of the lower mold 4, thus fixing the rubber sealing ring. The positioning pin ensures the alignment of the upper and lower molds 4;

[0027] The first motor is started to drive the turntable 42 to rotate, and the second motor is started to drive the main gear 41 to mesh with the sub-gear 44 and rotate, so that the cutter 422 rotates around the rubber sealing ring;

[0028] The cutter 422 on the pillar 421 moves as the turntable 42 and the sub-gear 44 rotate. The cutter 422 is located at the mating part of the upper and lower molds 4, and the cutter 422 can effectively remove the burrs on the rubber sealing ring;

[0029] When the burr removal is completed, the first cylinder 22 retracts, causing the upper mold 3 to rise and separate from the lower mold 4. At this time, the second cylinder 21 remains stationary, then the upper sealing seat flips by a certain angle, and the formed sealing ring is blown out through the air hole 431, and then the second cylinder 21 resets;

[0030] The moving cylinder 11 is started, causing the lower mold 4 to move along the slide rail on the workbench 1, facilitating the operator to take out the rubber sealing ring that has been deburred. The lower mold 4 is reset to the initial position to prepare for the processing of the next rubber sealing ring.
