Description

TECHNICAL FIELD

[0001] The present application relates to a graphite mold, in particular to a graphite mold for product surface treatment, and relates to an assembly method, in particular to an assembly method of a graphite mold for product surface treatment, and belongs to the technical field of graphite molds. BACKGROUND

[0002] However, the glass on the current photovoltaic panel is still a significant technical pain point in the material transfer and transport control process of the graphite mold for its surface forming in actual industrial production, which limits the production efficiency and stability. The specific problems are as follows: On the one hand, in the material transfer and transport link, the glass blank on the photovoltaic panel needs to be positioned by a clamp first, then the top of the mold is accurately rotated by a servo motor, and the depth of the downward movement is accurately controlled by a cylinder. Three steps need to be controlled independently and the time sequence needs to be manually preset. Parameter deviation can easily cause the blank and the mold to be misaligned, causing the blank to be damaged or the mold to be bumped. On the other hand, in the mold assembly and opening control link, after the blank is put into the mold, the hydraulic system needs to be started separately to close the mold, and then the mold is opened manually after forming. An independent device is used to transfer the bottle body. There is no linkage between the links, there is a production gap, and the production rate is reduced.

[0015] The beneficial effects of this invention are as follows: This invention provides a graphite mold and assembly method for product surface treatment. Through a rotary lifting mechanism consisting of a cylinder, an arc-shaped guide groove, a lower vertical groove, an upper vertical groove, and a second slider, a linkage control system is established with a contact switch. This integrates the traditionally separate "clamp positioning, servo motor rotation, and cylinder downward movement" steps into a single process. During operation, the second slider presses the contact switch as it slides along the guide groove, precisely triggering the opening and closing of the clamp. Combined with the rotational motion guided by the arc-shaped guide groove and the downward movement constrained by the upper and lower vertical grooves, the "rotation-downward movement" of the blank from the preheating station to the top of the mold is synchronized, eliminating the need for manually preset timing parameters. This design fundamentally avoids... It eliminates parameter deviations caused by independent control of each step, completely solves the problems of billet breakage and mold collision caused by misalignment between billet and mold, and significantly improves the stability and success rate of billet entry into the mold. In addition, the rotary lifting mechanism can complete the dual actions of rotation and lifting required for billet transfer with only a single cylinder, replacing the combination of multiple independent drive devices such as servo motors and cylinders in the traditional process. On the one hand, it reduces the number of drive components and reduces the manufacturing and procurement costs of the equipment. On the other hand, the design of a single drive source simplifies the installation, commissioning and subsequent maintenance process of the equipment, reduces downtime losses caused by the failure of multiple equipment, and further reduces the operation and maintenance costs in industrial production. The opening and closing mechanism, composed of a rectangular frame plate, support rods, linear guide grooves, inclined guide grooves, a first slider, a first spring, a hook-shaped extrusion rod, and a rotating roller, forms a deep linkage with the rotary lifting mechanism, creating a closed-loop operation chain of "bulk entry into mold - automatic mold closing - molding - automatic mold opening - finished product transfer". The hook-shaped extrusion rod is symmetrically fixed at both ends of the bottom of the upper mounting plate. When the blank is accurately entered into the mold through the rotary lifting mechanism, the action of the rotary lifting mechanism can directly drive the hook-shaped extrusion rod to extrude against the side mold, causing the first slider of the opening and closing mechanism to slide along the linear guide groove and the inclined guide groove, providing stable guidance for the side mold until the side mold and the lower mold are accurately fitted and closed. After molding, the opening and closing mechanism automatically drives the mold to open by the restoring force of the first spring, without manual intervention. Finally, the receiving platform of the receiving mechanism receives the finished product, eliminating the need for manual activation of the hydraulic system, triggering of mold opening, and calling of independent transfer equipment. This completely eliminates the waiting gap between each link, not only reducing the intensity of manual operation and the error rate, but also shortening the operation cycle of a single production line, increasing the number of products formed per unit time, and significantly enhancing the continuity and efficiency of industrial production.

[0018] To enable those skilled in the art to more clearly understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0019] like Figures 1-9 As shown, this embodiment provides a graphite mold for product surface treatment, including a base 1, a lower mold 2 fixed at one end of the top of the base 1, and side molds 3 symmetrically arranged at both ends of the top of the lower mold 2, and the side molds 3 and the lower mold 2 are adapted to form a cavity for product surface molding. The side mold 3 is provided with an opening and closing mechanism 4 on its outer side, which is used to drive the two sets of side molds 3 and the lower mold 2 to close synchronously to form a complete cavity, and to separate synchronously after molding to open the mold. A limiting rod 5 is vertically fixed on the side of the top of the base 1 near the lower mold 2. The top of the limiting rod 5 extends to the top of the lower mold 2. A limiting groove 6 is opened at the top of the limiting rod 5 to assist in limiting the movement trajectory of the blank transfer. A sleeve 7 is vertically fixed at the middle position of the top of the base 1. A sliding rod 8 is slidably arranged inside the sleeve 7. A rotating lifting mechanism 9 is provided inside the sleeve 7 to drive the sliding rod 8 to rise and fall vertically along the axis of the sleeve 7, and at the same time drive the sliding rod 8 to rotate horizontally around the axis. A crossbar 10 is fixed to the top of the slide rod 8. A fixing tube 11 is vertically fixed to the end of the crossbar 10 away from the slide rod 8. An upper mounting plate 12 is fixed to the bottom of the fixing tube 11. A lower mounting plate 13 is horizontally arranged at the bottom of the upper mounting plate 12. A second spring 14 is evenly arranged between the upper mounting plate 12 and the lower mounting plate 13. A clamp 15 is fixed to the bottom of the lower mounting plate 13. An air blowing pipe 16 is vertically arranged through the lower mounting plate 13. The bottom end of the air blowing pipe 16 is connected to the bottom of the lower mounting plate 13. The top end of the air blowing pipe 16 slides out from the inside of the fixing tube 11 and is connected to an external air source. A receiving mechanism 17 is provided at the top of the base 1 away from the lower mold 2, which is used to automatically receive the finished bottle after molding; A switch mechanism is provided on the top side of the sleeve 7 to automatically control the clamping and releasing action of the clamp 15 according to the lifting position of the slide rod 8.

[0020] Overall working principle: In the initial state, the clamp 15 is located at the top of the receiving mechanism 17. At this time, the second slider 905 in the rotary lifting mechanism 9 is at the top of the upper vertical groove 904 and maintains contact with the contact switch 19 in the switching mechanism. Since the contact switch 19 is electrically connected to the drive component of the clamp 15 through a wire, after the contact switch 19 is triggered, it sends an electrical signal to the drive component of the clamp 15, controlling the jaws of the clamp 15 to open, forming a space to accommodate the billet. The operator or conveying equipment places the preheated billet into the open jaws of the clamp 15, completing the initial positioning of the billet. After the billet is placed in place, cylinder 901 starts and retracts. Its output end drives slide rod 8 to move vertically downward through bearing. Slide rod 8 simultaneously drives the second slider 905 on the side wall to move vertically downward along the upper vertical groove 904. As the second slider 905 moves downward, it gradually separates from contact switch 19. Contact switch 19 stops sending electrical signals to the clamp 15 drive assembly. After the clamp 15 drive assembly loses the trigger signal, it automatically controls the jaws to close, firmly clamping the preheated billet and providing a stable clamping force for billet transfer. As cylinder 901 continues to retract, slide rod 8 drives second slider 905 from the top of lower vertical groove 903 into arc-shaped guide groove 902. Since arc-shaped guide groove 902 is arc-shaped and connected to lower vertical groove 903, second slider 905, guided by arc-shaped guide groove 902, drives slide rod 8 to rotate around the axis of sleeve 7 and move downwards. The crossbar 10 fixed at the top of slide rod 8 rotates synchronously with slide rod 8, and the fixing tube 11, upper mounting plate 12, lower mounting plate 13, and clamp 15 at the other end of crossbar 10 also rotate accordingly, thereby causing the clamped blank to rotate around the axis of sleeve 7. During the rotation of the billet, the limiting rod 5 at the top of the base 1 near the lower mold 2 plays a role: the top of the limiting rod 5 extends directly above the lower mold 2, and the limiting groove 6 it has opens to assist in limiting the movement trajectory of the billet. When the billet rotates to near the top of the lower mold 2, the edge of the billet enters the limiting groove 6, and the side wall of the limiting groove 6 forms a block and guide for the billet, correcting the rotation angle of the billet and ensuring that the billet accurately stops directly above the lower mold 2, avoiding rotational deviation that could lead to subsequent misalignment when entering the mold; After the blank is precisely positioned above the lower mold 2 under the limiting action of the limiting groove 6, the cylinder 901 continues to contract, driving the slide rod 8 to continue to move downward. The second slider 905 enters the lower vertical groove 903 from the bottom end of the arc-shaped guide groove 902 and slides vertically downward along the lower vertical groove 903. At this time, the slide rod 8 only performs vertical lifting and lowering movements and no longer rotates, driving the cross bar 10, the fixed tube 11 and the clamp 15 to move vertically downward. The blank held by the clamp 15 also moves vertically downward, gradually approaching the lower mold 2. Finally, the blank completely enters the cavity entrance formed by the lower mold 2 and the side mold 3, preparing for mold closing and forming. After the blank position is defined, the lower mounting plate 13 and the top of the limiting rod 5 are attached, fixing the blank position. The slide rod 8 can continue to move downwards. The slide rod 8 drives the hook-shaped extrusion rod 407 at the bottom of the upper mounting plate 12 to extrude the rotating roller 408 at the top of the side mold 3. This causes the side mold 3 to slide along the straight guide groove 403 of the rectangular frame plate 401 to the inclined guide groove 404 via the first slider 405, stretching the first spring 406 until the side mold 3 and the lower mold 2 close to form a complete cavity. Then, the external air blowing device blows air from the air blowing pipe 16, causing the blank to expand and adhere to the inner wall of the mold to form a shape. After the blank is formed in the cavity, the cylinder 901 drives the slide rod 8 to rise, the hook-shaped extrusion rod 407 disengages from the rotating roller 408, and the first spring 406 resets, pulling the side mold 3 back along the guide groove via the first slider 405 to achieve mold opening. Subsequently, the second slider 905 slides along the arc-shaped guide groove 902, rotating the molding material to the top of the receiving mechanism 17. The second slider 905 enters the upper vertical groove 904, moves up to the highest point and touches the contact switch 19. The contact switch 19 controls the clamp 15 to release, and the finished product falls onto the receiving platform 1702 of the receiving mechanism 17. The limiting sleeve 1703 positions the finished product, completing one molding cycle.

[0021] In this embodiment, guide rods 20 are vertically fixed at both ends of the top of the lower mounting plate 13. The guide rods 20 pass through the inside of the second spring 14 and extend to the top of the upper mounting plate 12. The guide rods 20 and the upper mounting plate 12 are slidably connected. The top of each guide rod 20 is fixed with a limit block 21, and the diameter of the limit block 21 is larger than the diameter of the mating hole between the guide rod 20 and the upper mounting plate 12.

[0022] Local working principle: When the sliding rod 8 drives the upper mounting plate 12 to move up and down, the guide rod 20 can slide along the mating hole of the upper mounting plate 12 to provide guidance for the movement of the lower mounting plate 13 and prevent the lower mounting plate 13 from deviating during the up and down movement. The second spring 14 is located between the upper mounting plate 12 and the lower mounting plate 13. When the clamp 15 clamps the blank and moves down to contact the limit rod 5, the second spring 14 will be squeezed and produce elastic deformation, which plays a buffering role and prevents the blank from being damaged due to excessive force.

[0023] In this embodiment, the rotary lifting mechanism 9 includes a cylinder 901, an arc-shaped guide groove 902, a lower vertical groove 903, an upper vertical groove 904, and a second slider 905. The cylinder 901 is vertically installed at the bottom of the inner end of the sleeve 7. The output end of the cylinder 901 is rotatably connected to the bottom end of the slide rod 8 through a bearing. An arc-shaped guide groove 902 is provided on the side wall of the sleeve 7. The bottom end of the arc-shaped guide groove 902 is connected to the lower vertical groove 903, and the top end of the arc-shaped guide groove 902 is connected to the upper vertical groove 904. The second slider 905 is slidably arranged inside the arc-shaped guide groove 902, the lower vertical groove 903, and the upper vertical groove 904. The end of the second slider 905 away from the guide groove is fixed on the outer side wall of the slide rod 8.

[0024] Partial working principle: When the cylinder 901 extends or retracts, driving the slide rod 8 to move, the second slider 905 slides within the guide groove. When the cylinder 901 retracts, the second slider 905 first slides downwards along the upper vertical groove 904, causing the slide rod 8 to move vertically downwards. Then it enters the arc-shaped guide groove 902. Due to the arc-shaped structure of the guide groove 902, the second slider 905 causes the slide rod 8 to rotate around the axis of the sleeve 7 during sliding, while continuing to move downwards. Finally, it enters the lower vertical groove 903 and moves vertically downwards along it, at which point the slide rod 8 only performs vertical movement. When the cylinder 901 extends, the second slider 905 slides along the opposite trajectory, realizing the upward movement and reverse rotation of the slide rod 8. Thus, through the rotation and lifting / lowering actions of the slide rod 8, the crossbar 10, the fixed tube 11, and the clamp 15 are driven to complete the transfer of the blank.

[0025] In this embodiment, the switching mechanism includes a fixing block 18 and a contact switch 19. The fixing block 18 is fixed on the outer wall of the sleeve 7 and located at the top of the upper vertical groove 904. The contact switch 19 is installed at the bottom of the fixing block 18. The contact switch 19 is electrically connected to the drive assembly of the clamp 15 through a wire, and the second slider 905 contacts the contact switch 19 when it rises to the highest point.

[0026] Local working principle: When the second slider 905 rises to the highest point, it will contact the contact switch 19. After the contact switch 19 is triggered, it sends an electrical signal to the clamp 15 drive assembly to control the clamp 15 to open, so as to place the billet or release the finished product. When the second slider 905 moves down from the highest point and separates from the contact switch 19, the contact switch 19 stops sending signals, and the clamp 15 drive assembly controls the jaws to close, so as to clamp the billet. Thus, the clamping and releasing actions of the clamp 15 are automatically controlled according to the lifting position of the slide rod 8.

[0027] In this embodiment, the opening and closing mechanism 4 includes a rectangular frame plate 401, a support rod 402, a straight guide groove 403, an inclined guide groove 404, a first slider 405, a first spring 406, and a hook-shaped pressing rod 407. The rectangular frame plate 401 is sleeved on the outside of the two sets of side molds 3. The support rod 402 is fixed between the bottom of the rectangular frame plate 401 and the base 1. The straight guide grooves 403 are symmetrically opened on both sides of the rectangular frame plate 401. The straight guide grooves 403 are connected to the inclined guide grooves 404 at the end of the straight guide grooves 403 near the lower mold 2. The first slider 405 is fixed on the side of the side mold 3 near the rectangular frame plate 401. The first slider 405 is slidably embedded in the inside of the straight guide grooves 403 and the inclined guide grooves 404. The first spring 406 is evenly provided between the outer end face of the side mold 3 and the inner end face of the rectangular frame plate 401. The hook-shaped pressing rod 407 is symmetrically fixed at both ends of the bottom of the upper mounting plate 12. The bottom end of the hook-shaped pressing rod 407 is adapted to the top of the side mold 3.

[0028] Local working principle: When the slide rod 8 moves the upper mounting plate 12 downward, the hook-shaped extrusion rod 407 at the bottom of the upper mounting plate 12 will extrude the side mold 3. Under the extrusion force, the side mold 3 drives the first slider 405 to slide along the straight guide groove 403 to the inclined guide groove 404, the first spring 406 is stretched, and the side mold 3 gradually moves towards the middle until it closes with the lower mold 2 to form a complete cavity; when the slide rod 8 moves the upper mounting plate 12 upward, the hook-shaped extrusion rod 407 disengages from the rotating roller 408, the first spring 406 recovers its deformation, pulls the side mold 3 to move the first slider 405 back along the guide groove, and the side mold 3 separates from the lower mold 2 to achieve mold opening.

[0029] In this embodiment, a rotating roller 408 is rotatably mounted on the edge of the top of the side mold 3, and the axis of the rotating roller 408 is parallel to the width direction of the base 1. The bottom end of the hook-shaped extrusion rod 407 rolls in contact with the outer side wall of the rotating roller 408.

[0030] Local working principle: When the hook-shaped extrusion rod 407 moves down to extrude the side mold 3, the bottom end of the hook-shaped extrusion rod 407 rolls into contact with the outer wall of the rotating roller 408, converting the vertical downward movement of the hook-shaped extrusion rod 407 into the rotation of the rotating roller 408, while simultaneously pushing the side mold 3 to move horizontally. This effectively reduces the sliding friction between the hook-shaped extrusion rod 407 and the side mold 3, reduces the wear of the components, and improves the smoothness and service life of the opening and closing mechanism 4.

[0031] In this embodiment, two sets of linear guide grooves 403 are provided at both ends of the rectangular frame plate 401, and the two sets of linear guide grooves 403 are distributed in parallel up and down along the height direction of the rectangular frame plate 401. Each set of linear guide grooves 403 is equipped with a first slider 405.

[0032] Local working principle: When the side mold 3 moves under the action of the hook-shaped extrusion rod 407, the two sets of first sliders 405 slide in the corresponding straight guide grooves 403 respectively, guiding the movement of the side mold 3 from the upper and lower positions, avoiding tilting or offset of the side mold 3 during the movement, ensuring that the side mold 3 can accurately close with the lower mold 2, and improving the accuracy and stability of mold closing.

[0033] In this embodiment, both the second slider 905 and the first slider 405 are cylindrical in shape, and the outer walls of both the second slider 905 and the first slider 405 are coated with a polytetrafluoroethylene wear-resistant coating with a coating thickness of 0.1-0.3 mm.

[0034] Local working principle: The cylindrical structure makes the slider slide more evenly and move more smoothly when sliding in the guide groove; the polytetrafluoroethylene coating has excellent wear resistance and low coefficient of friction, which can significantly reduce the friction and wear between the slider and the guide groove, extend the service life of the slider and the guide groove, and at the same time reduce the resistance when the slider slides, ensuring the stability and reliability of the operation of the rotary lifting mechanism 9 and the opening and closing mechanism 4.

[0035] In this embodiment, the receiving mechanism 17 includes a support column 1701, a receiving platform 1702, and a limiting sleeve 1703. The receiving platform 1702 is horizontally and parallelly arranged at the top of the base 1 away from the lower mold 2. The support column 1701 is evenly arranged between the bottom of the receiving platform 1702 and the base 1. The limiting sleeve 1703 is vertically arranged at the top of the receiving platform 1702, and the inner diameter of the limiting sleeve 1703 is adapted to the outer diameter of the finished bottle.

[0036] Local working principle: After the finished bottle is released by the clamp 15, it will fall onto the receiving platform 1702. The limiting sleeve 1703 can position the finished bottle to prevent it from rolling and shifting on the receiving platform 1702, which facilitates the subsequent collection and transfer of the finished bottle, realizing the automatic acceptance and positioning of the finished bottle after molding.

[0037] likeFigures 1-9 As shown in the figure, this embodiment provides an assembly method for a graphite mold used for product surface treatment. The process is as follows: Step 1: Assembly of base 1 and lower mold 2. Fix the lower mold 2 to one end of the top of base 1 with bolts, ensuring that the center line of the lower mold 2 is parallel to the length direction of base 1, and that the two ends of the lower mold 2 are equidistant from the side of base 1. Step 2: Installation of the opening and closing mechanism 4. On the base 1, located outside the lower mold 2, the rectangular frame plate 401 is fixed by the support rod 402 so that the rectangular frame plate 401 is parallel to the side of the lower mold 2. Then, the first slider 405 is fixed to both ends of the side mold 3. The side mold 3 is then slidably installed in the straight guide groove 403 of the rectangular frame plate 401 by the first slider 405. The first spring 406 is installed between the side mold 3 and the rectangular frame plate 401. Step 3: Assembly of the rotary lifting mechanism 9. The cylinder 901 is vertically fixed to the bottom end inside the sleeve 7. The arc-shaped guide groove 902, the lower vertical groove 903 and the upper vertical groove 904 are machined on the side wall of the sleeve 7. The second slider 905 is fixed to the side wall of the slide rod 8. Then the slide rod 8 is slidably inserted into the sleeve 7 through the cooperation of the second slider 905 and the guide groove. The output end of the cylinder 901 is connected to the bottom end of the slide rod 8 through the bearing. Finally, the assembled sleeve 7 is fixed in the middle position of the top of the base 1. Step 4: Install the blank clamping assembly. Fix one end of the crossbar 10 to the top of the slide rod 8, fix the fixing tube 11 to the other end of the crossbar 10, and fix the upper mounting plate 12 to the bottom of the fixing tube 11. Then, pass the guide rod 20 through the second spring 14 and the upper mounting plate 12. Install the limiting block 21 at the top of the guide rod 20 and fix the lower mounting plate 13 at the bottom. Finally, install the clamp 15 at the bottom of the lower mounting plate 13 and install the air blowing pipe 16 through the lower mounting plate 13 so that the top of the air blowing pipe 16 protrudes from the fixing tube 11. Step 5: Install auxiliary components. Fix the limiting rod 5 on the side of the base 1 near the lower mold 2, and machine the limiting groove 6 at the top of the limiting rod 5. At the same time, fix the fixing block 18 on the top outer side of the sleeve 7, and install the contact switch 19 at the bottom of the fixing block 18. Connect the contact switch 19 to the drive assembly of the fixture 15 through the wire. Step 6: Installation of receiving mechanism 17. At the top of base 1 away from lower mold 2, fix receiving platform 1702 with support column 1701 to ensure that the top surface of receiving platform 1702 is horizontal. Then install limiting sleeve 1703 on the top of receiving platform 1702 to complete the assembly of the entire mold.
