Description

Technical Field

[0001] This utility model relates to the field of hot press technology, and in particular to a hot press for resin grinding wheels. Background Technology

[0002] Resin grinding wheels are grinding wheels made from resin. They are generally formed by hot pressing.

[0003] When the hot press is working, the raw materials and binders are added into the mold, and then the hot press block is pressed down and heated in the mold, so that the material is condensed and hardened into a resin grinding wheel.

[0004] The resin grinding wheel formed by hot pressing is completely embedded inside the mold, and the hot pressing process can also cause the formed resin grinding wheel to stick to the inside of the mold, making it very difficult for workers to remove the resin grinding wheel from the mold. For this reason, we provide a hot press for resin grinding wheels that makes demolding easy. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] This utility model provides, for example Figures 1-2 The hot press for resin grinding wheels shown includes a worktable 101, a hot pressing mechanism, and a lifting mechanism. The hot pressing mechanism is located above the worktable 101, and a lifting mechanism is provided at the top of the hot pressing mechanism. The lifting mechanism is located inside the hot pressing mechanism and is used to eject the molded resin grinding wheel. The resin grinding wheel is molded by the hot pressing mechanism, and then the molded resin grinding wheel is ejected upward from the hot pressing mechanism by the lifting mechanism, which makes it convenient for the operator to remove the resin grinding wheel, thereby improving the convenience of resin grinding wheel demolding.

[0033] The hot pressing mechanism includes a mold base 201 and a hot pressing block 202. The mold base 201 is fixedly connected to the top of the worktable 101. A lifting mechanism is located inside the mold base 201. The hot pressing block 202 is located above the mold base 201 and is connected to the lifting mechanism. The material is placed inside the mold base 201, and then the hot pressing block 202 descends into the mold base 201 to hot press the material until the resin grinding wheel is formed.

[0034] The lifting mechanism includes a top seat 301, a first hydraulic cylinder 302, and a lifting seat 303. The top seat 301 is fixedly connected to the top of the workbench 101. The first hydraulic cylinder 302 is installed on the top of the top seat 301. The output end of the first hydraulic cylinder 302 passes through the top of the top seat 301 and is connected to the top of the lifting seat 303. The bottom end of the lifting seat 303 is fixedly connected to the bottom end of the hot pressing block 202. The lifting seat 303 can be lowered by the operation of the first hydraulic cylinder 302. The lowering of the lifting seat 303 can drive the hot pressing block 202 to lower, thereby improving the convenience of the hot pressing mechanism.

[0035] The top of the lifting seat 303 is fixedly connected to a guide rod 401, and the top of the top seat 301 is fixedly inserted with a guide sleeve 402. The outer wall of the guide rod 401 is movably inserted with the inner wall of the guide sleeve 402. The guide sleeve 402 limits and guides the guide rod 401, so that the lifting seat 303 will not rotate during the lifting process, ensuring that the hot pressing block 202 can be stably inserted into the mold seat 201 for hot pressing.

[0036] The lifting mechanism includes a top plate 501 and a fixed plate 502. The top plate 501 is fixedly connected to the inner wall of the mold base 201. The fixed plate 502 is located above the top plate 501 and is inserted into the inner wall of the mold base 201. A connecting mechanism is provided at the bottom end of the fixed plate 502. The resin grinding wheel is formed inside the mold base 201 and at the top of the fixed plate 502. After forming, the resin grinding wheel can be lifted upward by the rise of the fixed plate 502, making it convenient for workers to remove.

[0037] The connecting mechanism includes a connecting rod 602 and a roller 606. The top end of the connecting rod 602 is fixedly connected to the bottom end of the fixed plate 502. A connecting hole 601 is provided at the top end of the top plate 501. The outer wall of the connecting rod 602 is movably inserted into the inner wall of the connecting hole 601. A rotating groove 605 is provided at the bottom end of the connecting rod 602. The roller 606 is rotatably connected to the inner wall of the rotating groove 605. A movable block 603 is slidably arranged inside the mold base 201. The top end of the movable block 603... An inclined surface 604 is provided. A fixing ring 701 is fixedly sleeved on the outer wall of the connecting rod 602. A spring 702 is provided between the fixing ring 701 and the top plate 501. The spring 702 is sleeved on the outer wall of the connecting rod 602. A sliding groove 801 is provided on the outer wall of the mold base 201. A sliding rod 802 is slidably connected to the inner wall of the sliding groove 801. One end of the sliding rod 802 is fixedly connected to one side of the movable block 603. A third hydraulic cylinder 803 is installed at the top of the worktable 101. The output end of 03 is connected to the other end of the slide bar 802. The operation of the third hydraulic cylinder 803 drives the slide bar 802 to move. The movement of the slide bar 802 drives the movable block 603 to move until the inclined surface 604 contacts the roller 606. This causes the connecting rod 602 to be gradually lifted, thereby driving the fixed plate 502 to move upward. This pushes the molded resin grinding wheel upward out of the hot pressing block 202 until the operator removes it. Then, the operation of the third hydraulic cylinder 803 drives the slide bar 802 to move in the opposite direction. At this time, the movable block 603 moves in the opposite direction. Under the elastic force of the spring 702, the connecting rod 602 drives the fixed plate 502 to move downward gradually until the fixed plate 502 returns to its original position. The third hydraulic cylinder 803, the first hydraulic cylinder 302, and the hot pressing block 202 are electrically connected to the external wall power supply through external switches, which facilitates the operator's control of the third hydraulic cylinder 803, the first hydraulic cylinder 302, and the hot pressing block 202, improving the safety and convenience of operation.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
