Technical Field

[0001] The utility model relates to the technical field of electrode coating pressing molds, and particularly relates to a novel electrode coating pressing mold. Background Technique

[0002] An electrode consists of a welding core and a coating. The coating (coating) is evenly and concentrically pressed onto the welding core outside the metal welding core. Different types of electrodes have different welding cores. The welding core is the metal core of the electrode. To ensure the quality and performance of the weld seam, strict regulations are imposed on the content of each metal element in the welding core, especially on the content of harmful impurities (such as sulfur, phosphorus, etc.), which should be strictly restricted and be better than the base material. In the production and manufacturing of electrodes, there are two common methods for pressing the electrode coating: machine pressing and manual rubbing.

[0003] After retrieval, a coating pressing device for electrode production disclosed in a Chinese patent with the publication number CN218502505U can realize the pressing of small-sized electrodes through a pressing component, thus achieving a simple structure, easy operation, low cost for small-batch production of electrodes, dense and smooth surface of the produced electrodes, small consumption of powder, effectively improving the quality and production efficiency of the electrode coating, being suitable for small-batch production and manufacturing of electrodes, and meeting the needs of teaching experiments and scientific research and development of electrodes.

[0004] However, this device cannot quickly compact the coating in the mold plate, easily resulting in insufficient amount of coating for the produced electrodes, and low quality of electrode production, leading to unsatisfactory effects during the use of the produced electrodes and the problem of loose powder.

[0005] Therefore, a new solution is needed to solve this problem. Content of the Utility Model

[0006] Aiming at the problem in the above background technique that the existing technology cannot quickly compact the coating in the mold plate.

[0007] The novel electrode coating pressing mold disclosed by the utility model includes a fixed frame. The inner wall of the fixed frame is rotatably connected with two bidirectional screws. The inner wall of the fixed frame is fixedly connected with two sliding rods. The inner wall of the fixed frame is slidably connected with a connecting plate and a mold plate. The inner walls of the connecting plate and the mold plate are both slidably connected with the two sliding rods. The outer surface of each bidirectional screw is threadedly connected with the connecting plate and the mold plate. The inner wall of the connecting plate is slidably connected with a connecting rod. The bottom end of the connecting rod is fixedly connected with a pressing plate. The outer surface of the connecting rod is sleeved with a spring. The bottom end of the spring is fixedly connected with the pressing plate, and the other end is fixedly connected with the connecting plate. The top end of the connecting rod is fixedly connected with a fixing plate.

[0008] Further, a number of extrusion blocks are fixedly connected to the bottom surface of the pressing plate, and a number of loading grooves are formed inside the die plate, and the outer surface of each extrusion block is inserted into the corresponding loading groove.

[0009] Further, two hydraulic rods are provided above the fixing plate, and the upper surface of the fixing frame is fixedly connected to both hydraulic rods.

[0010] Further, a double-shaft motor is fixedly installed on the upper surface of the fixing frame, and fixing rods are fixedly connected to both output ends of the double-shaft motor, and first bevel gears are fixedly connected to the mutually remote ends of the two fixing rods.

[0011] Further, a second bevel gear is meshed with the outer surface of each first bevel gear, and the bottom surface of each second bevel gear is fixedly connected to the corresponding bidirectional screw.

[0012] Further, two connecting frames are fixedly installed on the upper surface of the fixing frame, and the inner walls of each connecting frame are rotatably connected to the corresponding fixing rod and bidirectional screw.

[0013] Further, an extrusion rod is fixedly connected to the upper surface of the fixing frame, the outer surface of each extrusion rod is inserted into the corresponding loading groove, a welding core is inserted into the inner wall of each loading groove, a stopper is slidably connected to the outer surface of each welding core, and the outer surface of each stopper is slidably connected to the corresponding loading groove.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. By arranging components such as a fixing frame, a bidirectional screw, a connecting plate, a die plate, a sliding rod, a connecting rod, a pressing plate, and a fixing plate, the present utility model drives the connecting plate and the die plate to move towards or away from each other simultaneously through the mutual cooperation and rotation of the two bidirectional screws. During this process, the pressing plate will contact and press the die plate, and the spring will be compressed, and the connecting rod will slide vertically along the connecting plate. At this time, the elastic force of the spring acts on the pressing plate and presses the coating in the die plate, thereby achieving the effect that the device can quickly compact the coating in the die plate through the setting of the pressing plate.

[0016] 2. By arranging components such as an extrusion rod, a loading groove, a welding core, and a stopper, the present utility model inserts the stopper into the corresponding welding core, then inserts the welding core with the stopper into the corresponding loading groove, and then pours the coating into the loading groove. At this time, the setting of the baffle can prevent the coating from leaking out of the loading groove. After the production of the welding rod is completed, by moving the die plate to move vertically downward along the fixing frame, the extrusion rod will squeeze the corresponding welding core and enter the corresponding loading groove, thereby achieving the effect that the device can facilitate the removal of the welding rod through the setting of the extrusion rod.
