Technical Field

[0001] This utility model relates to the field of graphite electrode mold technology, and in particular to a graphite electrode processing mold. Background Technology

[0002] Graphite electrodes are high-temperature resistant graphite conductive materials made from petroleum coke and pitch coke as aggregates and coal tar pitch as binders through processes such as calcination, crushing and grinding, batching, mixing, molding, baking, impregnation, graphitization, and machining. They are called artificial graphite electrodes (or simply graphite electrodes) to distinguish them from natural graphite electrodes made from natural graphite.

[0003] Currently, conventional graphite electrode molds are difficult to demold after injection molding, which affects processing efficiency and demolding safety. In addition, fixing the upper and lower molds is also quite troublesome.

[0004] Therefore, those skilled in the art have provided a graphite electrode processing mold to solve the problems mentioned in the background art. Utility Model Content

Through the set demolding mechanism, the graphite electrode can be quickly removed from the mold, making the operation more convenient. Furthermore, through the set fixing mechanism, the upper and lower molds can be quickly fixed together, making mold opening more convenient and improving processing efficiency to a certain extent.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0008] The demolding mechanism includes a motor, the output end of which passes through the outer wall of the lower mold and is connected to a bidirectional threaded rod. The outer walls of both ends of the bidirectional threaded rod are threaded with sliders. A second rotating seat is provided at the upper end of the slider. A base plate is provided at the bottom of the lower mold. Damping rods are provided at both ends of the lower end face of the base plate. A first spring is sleeved on the outer wall of the damping rod. A first fixing plate is provided at the bottom end of the damping rod. A first rotating seat is provided at the middle of the bottom end face of the first fixing plate. A connecting plate is rotatably connected between the first rotating seat and the second rotating seat.

[0009] The above technical solution allows the graphite electrode to be quickly removed from the mold using the designed demolding mechanism, making the operation relatively convenient.

[0010] Furthermore, the fixing mechanism includes a second fixing plate, a rotating rod is provided inside the second fixing plate, a first bevel gear is provided at both ends of the rotating rod, the first bevel gear is meshed with a second bevel gear, a threaded rod is provided at the lower end of the second bevel gear, an upper mold is provided on the upper end face of the lower mold, the two ends of the upper mold are threadedly connected to the threaded rod, and a driven wheel is provided at one end of the rotating rod;

[0011] The above technical solution, through the setting of a fixing mechanism, can quickly fix the upper and lower molds together, making mold opening more convenient and improving processing efficiency to a certain extent.

[0012] Furthermore, a drive wheel is provided at one end of the bidirectional threaded rod, and a belt connects the drive wheel and the driven wheel;

[0013] The above technical solution enables the demolding mechanism and the fixing mechanism to work together.

[0014] Furthermore, fixing rods are provided on both sides of the lower end face of the upper mold, and a slot is provided on one side of the lower end of the outer wall of the fixing rod;

[0018] Furthermore, an anti-slip pad is provided at the bottom of the base;

[0019] The above technical solutions can improve the stability of the device.

[0020] Furthermore, a controller is provided on one side of the upper surface of the base, and the controller and the motor cooperate with each other;

[0021] The above technical solution facilitates the control of internal electrical components and makes operation convenient.

[0022] Furthermore, sealing strips are provided at the joints between the upper mold and the lower mold, as well as between the bottom plate and the lower mold.

[0023] The above technical solutions improve the sealing performance of the device's internal components.

[0024] This utility model has the following beneficial effects:

[0025] 1. The graphite electrode processing mold proposed in this utility model, before injection molding, controls the rotation of the bidirectional threaded rod by the controller, thereby driving the two sliders to move. Since the upper end of the slider and the lower end of the first fixed plate are respectively provided with the connecting plate between the second rotating seat and the first rotating seat, the first fixed plate drives the bottom plate to move downward. When the upper mold reaches the lower mold, the damping rod has been pulled out a certain distance. After injection molding is completed, the first fixed plate moves upward at the same time, and after the damping rod is compressed to its original position, the upper mold has moved upward a certain position, which facilitates the removal of the graphite electrode after injection molding. Through the set demolding mechanism, the graphite electrode can be quickly removed from the mold, and the operation is relatively convenient.

[0026] 2. The graphite electrode processing mold proposed in this utility model has a belt connecting the driving wheel and the driven wheel, which causes the rotating rod to drive the second bevel gear, which is meshed with the first bevel gear, to rotate. This causes the threaded rod to rotate, thereby moving the upper mold. When the upper mold moves onto the lower mold, the slot and the locking block on one side of the outer wall of the fixing rod engage, thereby fixing the upper mold. When demolding, it is only necessary to pull the pull rod outward to disengage the slot and the locking block, and then move the upper mold upward through the electrode to remove the graphite electrode. Through the fixed mechanism, the upper and lower molds can be quickly fixed together, and the mold opening is also relatively convenient, which improves the processing efficiency to a certain extent.

[0036] The demolding mechanism 1 includes a motor 101. The output end of the motor 101 passes through the outer wall of the lower mold 5 and is connected to a bidirectional threaded rod 102. The outer walls of both ends of the bidirectional threaded rod 102 are threaded with sliders 106. The upper end of the sliders 106 is provided with a second rotating seat 107. The bottom end of the lower mold 5 is provided with a base plate 103. The lower end face of the base plate 103 is provided with damping rods 110 at both ends.

The middle of the bottom end face of the first fixing plate 108 is provided with a first rotating seat 104. The first rotating seat 104 and the second rotating seat 107 are rotatably connected by a connecting plate 105. Through the demolding mechanism 1, the graphite electrode can be quickly removed from the mold, which is convenient to operate. One end of the bidirectional threaded rod 102 is provided with a driving wheel 111. The driving wheel 111 and the driven wheel 202 are connected by a belt 203, so that the demolding mechanism 1 and the fixing mechanism 2 can be linked together.

[0037] Reference Figure 1 , Figure 2and Figure 5 The fixing mechanism 2 includes a second fixing plate 201, inside which a rotating rod 207 is provided. First bevel gears 208 are respectively provided at both ends of the rotating rod 207, and the first bevel gears 208 are meshed with a second bevel gear 209. A threaded rod 204 is provided at the lower end of the second bevel gear 209. An upper mold 205 is provided on the upper surface of the lower mold 5, and both ends of the upper mold 205 are threadedly connected to the threaded rod 204. A driven wheel 202 is provided at one end of the rotating rod 207. Through the fixing mechanism 2, the upper and lower molds can be quickly fixed together, and mold opening is also relatively convenient, improving processing efficiency to a certain extent. Fixing rods 210 are provided on both sides of the lower surface of the upper mold 205, and one side of the lower end of the outer wall of the fixing rod 210... A slot 211 is provided to facilitate the insertion of the locking block 212 into the slot 211. A pull rod 206 is provided through both sides of the outer wall of the lower mold 5. A second spring 213 is sleeved on the outer wall of the pull rod 206. A locking block 212 is provided at one end of the pull rod 206. The locking block 212 and the slot 211 cooperate with each other to fix the upper mold 205 onto the lower mold 5. An anti-slip pad 4 is provided at the bottom of the base 3 to improve the stability of the device. A controller 8 is provided on one side of the upper surface of the base 3.

[0038] Working principle: Before injection molding, the controller 8 controls the rotation of the bidirectional threaded rod 102, thereby driving the two sliders 106 to move. Since the upper end of the slider 106 and the lower end of the first fixed plate 108 are respectively provided with connecting plates 105 connecting the second rotating seat 107 and the first rotating seat 104, the first fixed plate 108 drives the base plate 103 to move downward. When the upper mold 205 reaches the lower mold 5, the damping rod 110 has been pulled out a certain distance. After injection molding is completed, the first fixed plate 108 moves upward and compresses the damping rod 110 to its original position. The upper mold 205 has moved upward a certain position, thus facilitating the completion of injection molding. After the graphite electrode is removed, the belt 203 connecting the drive wheel 111 and the driven wheel 202 causes the rotating rod 207 to drive the second bevel gear 209, which is meshed with the first bevel gear 208, to rotate, causing the threaded rod 204 to rotate, thereby driving the upper mold 205 to move. When the upper mold 205 moves onto the lower mold 5, the slot 211 and the locking block 212 on one side of the outer wall of the fixing rod 210 engage, thereby fixing the upper mold 205. When demolding, it is only necessary to pull the pull rod 206 outward to disengage the slot 211 and the locking block 212, and then the upper mold 205 is moved upward by the motor 101, thereby removing the graphite electrode.
