Description

Technical Field

[0001] This invention relates to a carbon fiber back mold assembly and disassembly device, belonging to the technical field of back mold assembly and disassembly devices. Background Technology

[0002] Carbon fiber molding dies typically use an upper and lower mold assembly. The carbon fiber needs to be manually distributed and filled into the cavities of both molds, necessitating the flipping of the upper mold. Since a single mold weighs 200-250 kg, mold assembly and disassembly equipment is required. Traditional equipment simply lifts the top mold vertically to disassemble it, generally without flipping it over. This mold requires a separate flipping device. However, existing flipping devices have horizontally oriented flipping ends. When flipping a 200-250 kg top mold, the screws at the horizontal connections of the flipping ends are prone to breakage and loosening due to excessive load. Furthermore, excessive lateral support can deform and damage the horizontal structure on the flipping end, making it unsuitable for the disassembly and flipping of this heavy-duty mold. To address these needs, this invention proposes a carbon fiber back-mounted mold assembly and disassembly device. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a carbon fiber back mold assembly and disassembly device to solve the existing problems.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a carbon fiber back-mounted mold assembly and disassembly device, the structure of which includes a conveyor frame, and a flip-back gantry frame is provided on the top surface of the rear end of the conveyor frame. Two automatic force conveying wheel bodies are longitudinally symmetrically arranged on the left and right sides of the top surface of the conveyor frame, and mold components are placed back and forth on the two automatic force conveying wheel bodies. An auxiliary mold pulling mechanism is longitudinally mounted on the middle of the front end of the top surface of the conveyor frame to assist in pulling backward when the automatic force conveying wheel bodies do not provide sufficient power to the mold components at the front end. Four bottom mold fixing mechanisms are symmetrically mounted on the rear end of the top surface of the conveyor frame. Two top mold pushing mechanisms are provided on the left and right sides of the rear end of the top surface of the conveyor frame. Two load-bearing and dispersing flip-back devices are symmetrically mounted on the left and right sides of the inner end of the flip-back gantry frame. A car-locking mechanism body is provided on the front side of the conveyor frame for car-locking after the external moving vehicle is assembled and spliced. The two load-bearing distributed flipping devices include a main load-bearing hanger assembly, and a rotating spline seat assembly is laterally nested at the lower end of the main load-bearing hanger assembly. A spline moving shaft assembly is laterally telescopically fitted in the middle of the rotating spline seat assembly. A drive shaft assembly is laterally arranged on the right side of the spline moving shaft assembly. Multiple rotating force-bearing sliding rods are arranged in a circular array between the right side of the spline moving shaft assembly and the left side of the drive shaft assembly. A stabilizing mechanism for pressing and supporting the drive shaft assembly after repeated 180º rotation is provided on the lower right side of the main load-bearing hanger assembly. A servo motor is driven to the right tail of the drive shaft assembly. The upper end of the main load-bearing hanger assembly is vertically fixed to the bottom surface of the upper end of the flipping gantry frame. The right end of the drive shaft assembly is laterally fitted onto the left side frame of the flipping gantry frame. The mold assembly is formed by the upper and lower molds of the bottom mold and the top mold. Multiple trapezoidal slots are opened in the middle of the front and rear sides of the top mold, and multiple hanging columns are extended outward from the sides of the front and rear sides of the top mold. A pull ring seat is provided in the middle of the right side of the top mold. The rotary spline seat assembly includes a spline seat body, and a spline slide is provided through the middle of the spline seat body. Two pressure-bearing turntable bodies are nested on the front and rear sides of the spline seat body. The spline moving shaft assembly includes a spline transverse slide column that engages with the spline slide rail, and a trapezoidal sleeve block that movably engages with the trapezoidal sleeve groove is provided in the middle of the left side of the spline transverse slide column, and a buffer pressure seat body is provided in the middle of the right side of the spline transverse slide column.

[0005] A further improvement is that a longitudinal pull slide is longitudinally opened at the middle of the front end of the top surface of the conveyor frame to assist the pulling mold mechanism in lifting and moving, and multiple movable openings are spaced apart at the rear end of the top surface of the conveyor frame for the bottom mold fixing mechanism to lift and move.

[0006] A further improvement is that the auxiliary pulling mechanism includes two tracks, on which pull seats are fitted, and a lead screw is threaded to the bottom of the pull seat. A motor is driven to the rear end of the lead screw, and a pull hook assembly is lifted and fitted in the middle of the pull seat. The hook assembly includes a first support, and a first hydraulic cylinder is vertically mounted in the middle of the first support. A lifting support seat is horizontally arranged on the top surface of the first hydraulic cylinder. A hook component is horizontally hinged on the lifting support seat. A first tension spring is hooked and connected in the middle between the lifting support seat and the hook component. Multiple first sliding rods for passing through the first support are vertically arranged on the left and right sides of the lifting support seat. The left end of the hook component is respectively provided with a hook opening and an arc-shaped push surface.

[0007] A further improvement is that each of the aforementioned bottom mold fixing mechanisms includes a second support, and the upper end of the second support is hinged to a multi-chain rod body, and the upper end of the multi-chain rod body is laterally hinged to a longitudinal push rod. A second hydraulic cylinder is vertically arranged on the right side of the second support, and the top surface of the second hydraulic cylinder is provided with an arc-shaped triangular abutment block that moves to push the bottom surface of the right end of the multi-chain rod body. A second tension spring is hooked and connected between the right end of the longitudinal push rod and the second support.

[0008] A further improvement is that each of the top mold lifting mechanisms includes a third hydraulic cylinder, and a lifting frame is horizontally arranged on the top surface of the third hydraulic cylinder. Two push seats are arranged on the left and right sides of the top surface of the lifting frame. A hanging column positioning sleeve is opened in the middle of the two push seats. An anti-jamming groove is opened in the middle of the lifting frame. Two second slide rods are vertically arranged on the left and right sides of the lifting frame and are fitted onto the conveyor frame.

[0009] A further improvement is that the main load-bearing hanger assembly includes a circular sleeve, and the central part of the circular sleeve has a rotating opening for the nesting of the rotating spline seat assembly, and the front and rear edges of the rotating opening have pressure-bearing turntable grooves, and the top surface of the circular sleeve is vertically provided with a load-bearing hanger beam.

[0010] A further improvement is that the drive shaft assembly includes a drive spindle, and a bearing is fitted on the right side of the drive spindle shaft body. A telescopic groove is opened at the left end of the drive spindle. A fourth hydraulic cylinder is fitted in the middle of the left groove wall of the telescopic groove. The right ends of each of the rotating force-bearing slide rods are inserted into the telescopic groove in a circular array. Two stable abutments are horizontally aligned on the left side of the drive spindle shaft body.

[0011] A further improvement is that the stabilizing mechanism includes a third support, on which a fifth hydraulic cylinder is vertically mounted, and an inverted U-shaped abutment is mounted at the lower end of the fifth hydraulic cylinder. Two stabilizing blocks are mounted on the left and right ends of the bottom surface of the inverted U-shaped abutment to move and abut against the stabilizing abutment.

[0012] A further improvement is that the main body of the automatic force conveying wheel, the main body of the kala mechanism, the main body of the multi-chain rod, and the main body of the buffer pressure seat are all existing technologies, and their structures will not be described in detail here.

[0013] A further improvement is that the external mobile vehicle is also equipped with an automatic force conveying wheel body and an auxiliary pulling mechanism.

[0014] The beneficial effects of this invention are: This invention provides a carbon fiber backing mold assembly and disassembly device. Through a structural combination design of a conveyor frame, a flipping gantry frame, an automatic force conveying wheel body, a mold assembly, an auxiliary mold pulling mechanism, a bottom mold fixing mechanism, a top mold pushing mechanism, a load-bearing distributed flipping device, and a karaoke mechanism body, a carbon fiber backing mold assembly and disassembly device is formed. The auxiliary mold pulling mechanism assists in pulling the mold assembly when it is initially guided to the front end of the automatic force conveying wheel body, as insufficient power prevents the mold assembly from being fully guided to the front end of the automatic force conveying wheel body. Furthermore, the auxiliary mold pulling mechanism also has an automatic push-hook function, which effectively reduces the alignment and hooking steps, making operation simpler.

[0015] The bottom mold fixing mechanism assists the automatic force conveying wheel body in accurately guiding the mold assembly to the top mold pushing mechanism, and can also fix the bottom mold, so that when the top mold pushing mechanism vertically pushes the top mold, it prevents the bottom mold from being lifted up by the carbon fiber molding parts, thus preventing the bottom mold from being lifted up and falling and damaging the automatic force conveying wheel body.

[0016] The top mold lifting mechanism vertically lifts the top mold to a horizontal alignment with the load-bearing and distributing flipping device. After the load-bearing and distributing flipping device extends outward and engages with the top mold for support, the main load-bearing weight of the top mold is concentrated on the main load-bearing hanger assembly, the rotating spline seat assembly, and the spline moving shaft assembly. This ensures that the load-bearing and distributing flipping device will not experience screw breakage or structural deformation during long-term heavy-duty use. The drive shaft assembly and rotating force-bearing slide rod only bear rotational torque and can be used for a long time without damage. In addition, the stabilizing mechanism provides horizontal pressure support to the drive shaft assembly. Due to the different weight distribution of the top mold, the self-braking strength built into the servo motor is insufficient, which could easily lead to the servo motor rotating under the drive of the top mold. The above-mentioned load-bearing and distributing flipping device reasonably distributes the load of the top mold, reduces the use of screws on the main load-bearing hanger assembly, the rotating spline seat assembly, and the spline moving shaft assembly on the main load-bearing end, and shortens the lateral structure, making the flipping operation of heavy mold components such as the load-bearing and distributing flipping device more efficient and stable.

[0025] The drive shaft assembly 84 includes a drive spindle 841, and a bearing 842 is fitted on the right side of the shaft of the drive spindle 841. A telescopic groove 843 is provided on the left end of the drive spindle 841. A fourth hydraulic cylinder 844 is fitted in the middle of the left groove wall of the telescopic groove 843.

[0026] The stabilizing mechanism 86 includes a third support 861, on which a fifth hydraulic cylinder 862 is vertically arranged, and an inverted U-shaped abutment 863 is arranged at the lower end of the fifth hydraulic cylinder 862. Two stabilizing blocks 864 are arranged at the left and right ends of the bottom surface of the inverted U-shaped abutment 863 to move and abut against the stabilizing abutment 845.

[0027] Working principle: During operation, the mold assembly 4 is first transferred by an external moving vehicle. After the external moving vehicle is transferred and aligned with the front end of the conveyor frame 1, it is tightened and positioned by the main body 9 of the karaoke mechanism. This is existing technology and will not be described in detail here.

[0028] Then, the automatic force conveying wheel body 3 on the external moving vehicle conveys the mold assembly 4 towards the conveyor frame 1. When it is conveyed to the front end of the automatic force conveying wheel body 3 on the conveyor frame 1, because the mold assembly 4 is in the closed state, the weight of the mold assembly 4 reaches 400-500kg, and only a small part of the front end of the mold assembly 4 is on the front end of the automatic force conveying wheel body 3. Directly guiding it through the automatic force conveying wheel body 3 will result in insufficient power and failure to guide it. At this time, it is necessary to use the auxiliary mold pulling mechanism 5 to assist in pulling the mold. First, the first cylinder 552 pushes the hook part 554 upward in the first stroke, so that the hook part 554 is horizontally aligned with the pull ring seat 45. Then, the motor 54 drives the lead screw 53 to rotate forward and backward, so that the pull ring seat 554 is horizontally aligned with the pull ring seat 45. 52 moves longitudinally back and forth on two tracks 51. When moving forward, the hook 554 moves towards the pull ring seat 45. Under the action of the arc-shaped push surface 558 and the first tension spring 555, the front end of the hook 554 is pushed up so that the hook opening 557 hooks and connects with the pull ring seat 45, reducing the alignment steps between the hook opening 557 and the pull ring seat 45. Then, the auxiliary pulling mold mechanism 5 pulls the mold assembly 4 backward, so that the mold assembly 4 is placed on the front end of the automatic force conveying wheel body 3. Then, the second stroke of the first oil cylinder 552 pushes the hook 554 to rise again, so that the hook opening 557 disengages from the pull ring seat 45. Then, the hook 554 is moved backward, and finally the hook 554 is lowered to below the bottom surface of the mold assembly 4.

[0029] Then, the automatic force conveying wheel body 3 transports the mold assembly 4 backward to the relative positions of the two top mold lifting mechanisms 7. Then, the four bottom mold fixing mechanisms 6 precisely push the mold assembly 4 to align and fix the bottom mold 41. The second oil cylinder 64 drives the arc-shaped triangular abutment block 65 to rise and push the multi-chain rod body 62 to move, so that the longitudinal push rod 63 rises and moves longitudinally towards the bottom mold 41. The hinged design of the multi-chain rod body 62 and the longitudinal push rod 63 increases the longitudinal pushing force, realizes the precise alignment of the mold assembly 4, and makes the hanging column 44 vertically aligned with the hanging column positioning sleeve 74. When the longitudinal push rod 63 is subsequently reset, the second tension spring 66 plays a role in assisting the longitudinal push rod 63 to pull outward and prevent jamming and descent.

[0030] Then, the third hydraulic cylinder 71 pushes the lifting frame 72 to rise. During this process, the hanging column 44 and the hanging column positioning sleeve 74 will be engaged, pushing the top mold 42 vertically. Under the action of the bottom mold fixing mechanism 6, the bottom mold 41 will not be lifted together with the carbon fiber forming part. When the top mold 42 is pushed up to be horizontally aligned with the two load-bearing and dispersing flipping devices 8, the trapezoidal sleeve groove 43 and the trapezoidal sleeve block 832 are horizontally aligned. Then, the bottom mold fixing mechanism 6 descends and resets, and moves the bottom mold 41 forward to offset it from the top mold 42, so as to facilitate the descent of the top mold 42 after the subsequent flipping operation.

[0031] Then the fourth cylinder 844 extends, causing the spline horizontal slide column 831 to move laterally within the spline slide rail 822, allowing the trapezoidal sleeve groove 43 and the trapezoidal sleeve block 832 to engage. In addition, the buffering and pressing action of the buffer pressing seat body 833 ensures that the trapezoidal sleeve groove 43 and the trapezoidal sleeve block 832 can be properly engaged during long-term use, and will not experience wear and disengagement problems due to long-term use. Then the top mold pushing mechanism 7 first resets, so that the main load of the top mold 42 is concentrated on the main load-bearing hanging seat assembly 81, the rotating spline seat assembly 82, and the spline moving shaft assembly 83, so that the load-bearing distribution flipping device 8 will not experience screw breakage or structural deformation problems during long-term load-bearing use.

[0032] When the load-bearing distributed flipping device 8 flips, the servo motor 87 drives the drive shaft assembly 84 to rotate 180º back and forth. Under the main rotational torque carried by the rotating force slide bar 85, the spline moving shaft assembly 83 and the rotating spline seat assembly 82 rotate on the two pressure-bearing turntable bodies 823. The spline horizontal slide column 831 and the spline slide rail 822 adopt a spline sleeve meshing method to increase the meshing torque and prevent wear due to long-term use. This causes the top mold 42 to flip. Then, the fifth oil cylinder 862 descends, so that the stabilizing block 864 and the stabilizing seat 845 abut against each other for stable support. Because the weight distribution of the top mold 42 is different, the self-braking strength built into the servo motor 87 alone is not enough. The servo motor 87 is prone to transmission and rotation problems under the drive of the top mold 42.

[0033] Then the top mold lifting mechanism 7 rises to support the top mold 42, and then the load-bearing dispersing and flipping device 8 resets, so that the trapezoidal sleeve groove 43 and the trapezoidal sleeve block 832 are disengaged. Then the top mold lifting mechanism 7 descends to place the top mold 42 on the automatic force conveying wheel body 3. Finally, the bottom mold 41 and the top mold 42 are transported forward to the external moving vehicle to complete the mold assembly 4 demolding and flipping operation. The mold closing method can be operated in the opposite way.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
