Description

Technical Field

[0001] This invention relates to the field of plastic molding, and more particularly to a composite material molding die for a target machine body. Background Technology

[0002] The wings on the target drone's fuselage are made of a composite material with plastic as the matrix, and are formed using wing molds. The plastic matrix in this composite material can be recycled after processing, and the recycled plastic can be reused as raw material for mold forming, forming a circular link of molded products, recycled plastic, and re-molding.

[0003] However, when using existing wing molds, in order to facilitate demolding of the molded wing, it is necessary to wipe the mold release agent on the inner surface of the mold, i.e. the mold cavity, beforehand. The method of wiping the mold release agent is mostly done manually by workers, which greatly increases the labor intensity of workers and makes it inconvenient to use. Summary of the Invention

The limiting wheel is attached to the inner wall of the square frame. A curved shell is fixedly installed at the lower end of the push shell frame. A curved wiping cloth is provided at the lower end of the curved shell.

[0008] Preferably, a wheel seat is fixedly installed on the other side of the sliding sleeve, and a pressure roller is installed at the end of the wheel seat. A slanted pressure frame is fixedly installed on one side of the upper end of the mold base. The slanted pressure frame is located on the side of the lower mold of the wing and is aligned with the pressure roller. A servo motor is provided above the square frame. The servo motor is fixed to the cross frame. The output end of the servo motor and the upper part of the outer surface of the tube shaft are coaxially inlaid with bevel gears, and the two bevel gears mesh with each other.

[0009] Preferably, a second flexible hose is fixedly connected between the curved shell and the tube shaft, a transmission pipe is fixedly installed at the upper end of the cross frame, the transmission pipe is rotatably connected to the upper end of the tube shaft, the end of the transmission pipe is fixedly connected to a first flexible hose, the arc-shaped shell and the concave shell are both fixedly connected to the first flexible hose, and multiple through holes are provided through the curved shell relative to the end face of the curved wiping cloth, the flat shell relative to the end face of the flat wiping cloth, the concave shell relative to the end face of the concave wiping cloth, and the arc-shaped shell relative to the end face of the arc-shaped wiping cloth.

[0010] Preferably, the front and rear ends of the carrier sleeve are fixedly installed with column bases, the upper end of the column base is fixedly installed with a circular guide post, the outer surface of the circular guide post is slidably installed with a column cap, the column cap is fixed to the sliding sleeve, and an upward spring is wound around the outer side of the circular guide post, the two ends of the upward spring are fixed to the column base and the column cap respectively.

[0011] Preferably, two guide columns are slidably installed through the middle of the pusher frame. The ends of the guide columns are fixed to the tube shaft. A tension spring is wound around the outside of the guide columns. The two ends of the tension spring are fixed to the pusher frame and the tube shaft, respectively. The tension spring is in a contracted state.

[0012] Preferably, a hexagonal guide post is fixedly installed at the upper end of the concave shell, the hexagonal guide post is slidably installed at the end of the extension frame, a downward spring is wound around the outer side of the hexagonal guide post, the two ends of the downward spring are respectively fixed to the concave shell and the extension frame, and the downward spring is in a contracted state.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Driven by the servo pusher cylinder, two arc-shaped wiping cloths are pushed towards the space between the upper and lower molds of the wing. At this time, the shrink wheel rolls on the shrink rail. When the arc-shaped wiping cloths are about to approach the edge of the cavity of the lower and upper molds of the wing, the shrink wheel rolls to the end slope of the shrink rail. At this time, under the action of the return spring, the shrink wheel will roll against the end slope of the shrink rail, and then the two arc-shaped wiping cloths will gradually move outward. When the outward-moving arc-shaped wiping cloths press against the edge of the cavity, the shrink wheel separates from the shrink rail. Then the servo pusher cylinder continues to drive the arc-shaped wiping cloths to move, so that the arc-shaped wiping cloths containing the release agent can press against the cavity and move to wipe the release agent on the cavity. The process does not require manual wiping by the worker, thus effectively reducing the labor intensity of the worker and making it convenient to use.

[0014] 2. When the arc-shaped wiping cloth is pushed forward, the concave wiping cloth will also be pushed forward simultaneously. At this time, the upper moving wheel rolls on the upper moving rail. When the concave wiping cloth approaches the long strip mold core on the lower mold of the wing, the upper moving wheel just rolls to the end slope of the upper moving rail. At this time, under the action of the lower moving spring, the upper moving wheel will roll against the end slope of the upper moving rail, thereby causing the concave wiping cloth to move down. When the lowered concave wiping cloth wraps around the outside of the long strip mold core, the upper moving wheel just separates from the upper moving rail. At this time, the pushed concave wiping cloth will wipe the surface of the long strip mold core and the corner of the long strip mold core and the lower mold of the wing, thereby reducing the dead corners of the release agent wiping and ensuring the demolding effect after molding.

[0015] 3. As the advancing arc-shaped wiping cloth approaches the end point of the cavity, the tube shaft is just close to the square groove. At the same time, the pressure roller is in contact with the inclined pressure frame and rolls along the lower inclined surface of the inclined pressure frame, allowing the sliding sleeve to slide down on the carrier sleeve, thereby driving the tube shaft down. When the arc-shaped wiping cloth advances to the end point of the cavity, the downward-moving tube shaft just moves to the center position of the square groove. At the same time, the flat wiping cloth on the tube shaft presses against the inner bottom surface of the square groove, and the curved wiping cloth presses against the edge of the square groove. At this point, the advancement stops, and then the servo motor works to drive the flat and curved wiping cloths on the tube shaft to rotate, so that the rotating flat wiping cloth can wipe the inner bottom surface of the square groove. At the same time, the limiting wheel, pushed by the top spring, will roll along the inner wall of the square frame, allowing the rotating curved wiping cloth to move in a square trajectory, that is, along the edge of the square groove, to wipe the corner of the square groove. This further reduces the dead corners of the release agent wiping and ensures the demolding effect after molding. Attached Figure Description

[0018] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0019] like Figures 1-9The target aircraft fuselage composite material molding die shown includes a mold base 1. A lower wing mold 2 is fixedly installed on one side of the upper end of the mold base 1. An upper wing mold 5 is set above the lower wing mold 2. The upper wing mold 5 is raised and lowered by a hydraulic cylinder or other means to open or close the mold. Since the above operation is existing technology and has been widely used, it is not described in detail here and is not shown in the figure. A servo push cylinder 8 is fixedly installed on the rear part of the other side of the upper end of the mold base 1. A connecting frame 47 is fixedly installed at the output end of the servo push cylinder 8. A carrier sleeve 20 is fixedly installed at the end of the connecting frame 47. The connecting frame 47 serves to connect the carrier sleeve 20. Two shell prisms 21 are symmetrically slidably installed inside the carrier sleeve 20. The carrier sleeve 20 serves to support the shell prisms 21. The two shell prisms 21 extend from the upper and lower ends of the carrier sleeve 20 respectively. An arc-shaped shell 15 is fixedly installed at the opposite ends of the two shell prisms 21. On the opposite side, there are arc-shaped wiping cloths 16. The arc-shaped shell 15 serves to support the arc-shaped wiping cloths 16. A return spring 48 is provided between the opposite ends of the two shell prisms 21 and the carrier sleeve 20. When the return spring 48 is in a contracted state, it can allow the two arc-shaped wiping cloths 16 to gradually move outward and press against the cavity. The front ends of the two shell prisms 21 are extended with a spreading wheel frame 22. The ends of the two spreading wheel frames 22 are equipped with shrinking wheels 12. The spreading wheel frame 22 serves to support the shrinking wheels 12. A fixing frame 17 is fixedly installed on the front part of the other side of the upper end of the mold base 1. Two shrinking rails 13 are symmetrically fixedly installed on the fixing frame 17. The fixing frame 17 serves to fix the shrinking rails 13. The two shrinking wheels 12 are respectively abutted on the two shrinking rails 13. The cooperation between the shrinking wheels 12 and the shrinking rails 13 can allow the two arc-shaped wiping cloths 16 to move inward and detach from the cavity when resetting. A wiping core is provided on the carrier sleeve 20.

[0020] The wiping core component includes an extension frame 24 fixedly installed on the lower edge of the side of the carrier sleeve 20. A concave shell 27 is elastically installed at the end of the extension frame 24, which serves as a connection. The groove of the concave shell 27 is adapted to the elongated mold core 4 on the lower mold of the wing 2, which can ensure that the concave wiping cloth 28 fully contacts the elongated mold core 4 to reduce the wiping dead angle. The lower end of the concave shell 27 is provided with the concave wiping cloth 28. The rear end of the concave shell 27 is fixedly installed with a connecting wheel frame 38. The end of the connecting wheel frame 38 is installed with an upper moving wheel 23, which serves to support the upper moving wheel 23. The lower part of the upper moving wheel 23 is fitted with an upper moving rail 14, which is fixed to the mold base 1. The cooperation between the upper moving wheel 23 and the upper moving rail 14 allows the concave wiping cloth 28 to move upward and disengage from the cavity during reset. A sliding sleeve 19 is slidably installed on the outer surface of the carrier sleeve 20, which serves as a guide.

[0021] A crossbeam 10 is fixedly installed on one side of the sliding sleeve 19, serving as a load-bearing component. A square frame 37 is fixedly installed at the end of the crossbeam 10. The size of the square frame 37 is adapted to the size of the square groove 3 on the lower wing mold 2, allowing the limiting wheel 41 to roll along the inner wall of the square frame 37. When the rotating curved wiping cloth 45 moves along a square trajectory, the curved wiping cloth 45 can move along the edge of the square groove 3 to wipe the corners of the square groove 3. A tube shaft 36 is provided at the center of the square frame 37, and the tube shaft 36 is rotatably connected to the crossbeam 10. The lower end of the tube shaft 36 is fixedly connected to a flat shell 40, and a flat wiping cloth 46 is provided at the lower end of the flat shell 40. The flat shell 40 serves to support the flat wiping cloth 46. A push shell frame 42 is elastically installed on the lower part of the outer surface of the tube shaft 36. A limiting wheel 41 is installed at the upper end of the push shell frame 42. The limiting wheel 41 is attached to the inner wall of the square frame 37, allowing the rotating curved wiping cloth 45 to move in a square trajectory. A curved shell 39 is fixedly installed at the lower end of the push shell frame 42. The push shell frame 42 serves to connect the curved shell 39. The curved wiping cloth 45 is provided at the lower end of the curved shell 39.

[0022] A wheel seat 7 is fixedly installed on the other side of the sliding sleeve 19. A pressure roller 30 is installed at the end of the wheel seat 7. The wheel seat 7 serves to support the pressure roller 30. A slanted pressure frame 6 is fixedly installed on one side of the upper end of the mold base 1. The slanted pressure frame 6 is located on the side of the lower mold 2 of the wing. The slanted pressure frame 6 is aligned with the pressure roller 30. The slanted pressure frame 6 can make the pressure roller 30 move down, thereby making the tube shaft 36 move down, so that the tube shaft 36 moves to the center position of the square groove 3. At the same time, the flat wiping cloth 46 on the tube shaft 36 presses against the inner bottom surface of the square groove 3, and the curved wiping cloth 45 presses against the edge of the square groove 3. A servo motor 9 is set above the square frame 37. The servo motor 9 is fixed to the cross frame 10. The output end of the servo motor 9 and the upper part of the outer surface of the tube shaft 36 are coaxially inlaid with bevel gears 35. The two bevel gears 35 mesh with each other, and the servo motor 9 can drive the tube shaft 36 to rotate through the bevel gears 35.

[0023] A second flexible hose 29 is fixedly connected between the bent shell 39 and the tube shaft 36. The second flexible hose 29 connects the bent shell 39 and the tube shaft 36 and ensures that the movement trajectory of the bent shell 39 is not obstructed. A transmission pipe 11 is fixedly installed at the upper end of the cross frame 10. The transmission pipe 11 is connected to an external facility for conveying release agent, allowing the release agent to be delivered into the bent shell 39, flat shell 40, concave shell 27, and arc-shaped shell 15. Since the delivery of release agent is existing technology and has been widely used, it is not described in detail here and is not shown in the figure. The transmission pipe 11 is rotatably connected to the upper end of the tube shaft 36, and the end of the transmission pipe 11 is fixedly connected to a first flexible hose 18 and the arc-shaped shell 15. Both the concave shell 27 and the first hose 18 are fixedly connected. The first hose 18 can connect the arc shell 15, the concave shell 27 and the transmission pipe 11, and ensure that the movement trajectory of the arc shell 15 and the concave shell 27 is not obstructed. The curved shell 39 relative to the end face of the curved wiping cloth 45, the flat shell 40 relative to the end face of the flat wiping cloth 46, the concave shell 27 relative to the end face of the concave wiping cloth 28, and the arc shell 15 relative to the end face of the arc wiping cloth 16 are all provided with multiple through holes. The design of the through holes allows the release agent in the curved shell 39, the flat shell 40, the concave shell 27 and the arc shell 15 to be discharged, thereby wetting the curved wiping cloth 45, the flat wiping cloth 46, the concave wiping cloth 28 and the arc wiping cloth 16 for wiping.

[0024] Both the front and rear ends of the carrier sleeve 20 are fixedly installed with column bases 31. A circular guide post 33 is fixedly installed on the upper end of the column base 31. The column base 31 serves to fix the circular guide post 33. A column cap 34 is slidably installed on the outer surface of the circular guide post 33. The column cap 34 is fixed to the sliding sleeve 19. An upward spring 32 is wound around the outer side of the circular guide post 33. The two ends of the upward spring 32 are fixed to the column base 31 and the column cap 34 respectively. The column cap 34 can be pushed by the upward spring 32, thereby driving the sliding sleeve 19 to move upward and reset.

[0025] Two guide posts 43 are slidably mounted through the middle of the pusher frame 42. The ends of the guide posts 43 are fixed to the tube shaft 36. The guide posts 43 guide the pusher frame 42. A tension spring 44 is wound around the outside of the guide posts 43. The two ends of the tension spring 44 are fixed to the pusher frame 42 and the tube shaft 36 respectively. When the tension spring 44 is in a contracted state, it can push the pusher frame 42, so that the limiting wheel 41 always rolls along the inner wall of the square frame 37, thereby allowing the rotating curved wiping cloth 45 to move in a square trajectory.

[0026] A hexagonal guide post 25 is fixedly installed at the upper end of the concave shell 27. The hexagonal guide post 25 is slidably installed at the end of the extension frame 24. The hexagonal guide post 25 serves to guide the concave shell 27. A downward spring 26 is wound around the outside of the hexagonal guide post 25. The two ends of the downward spring 26 are fixed to the concave shell 27 and the extension frame 24 respectively. When the downward spring 26 is in a contracted state, it can push the concave shell 27 downward, so that the concave wiping cloth 28 on the concave shell 27 can extend into the cavity and contact the elongated mold core 4.

[0027] In use, driven by the servo push cylinder 8, the two arc-shaped wiping cloths 16 are pushed towards the space between the upper wing mold 5 and the lower wing mold 2. At this time, the retraction wheel 12 rolls on the retraction rail 13. When the arc-shaped wiping cloths 16 are about to approach the edge of the cavity of the lower wing mold 2 and the upper wing mold 5, the retraction wheel 12 just rolls to the end slope of the retraction rail 13. At this time, under the action of the return spring 48, the retraction wheel 12 will roll against the end slope of the retraction rail 13, thereby causing the two arc-shaped wiping cloths 16 to gradually move outward. When the outward-moving arc-shaped wiping cloths 16 press against the edge of the cavity, the retraction wheel 12 just separates from the retraction rail 13, and then the servo push cylinder 8 continues to drive the arc-shaped wiping cloths. 16 moves, allowing the arc-shaped wiping cloth 16 containing the release agent to press against the cavity and move, wiping the release agent onto the cavity. When the arc-shaped wiping cloth 16 is pushed forward, the concave wiping cloth 28 is also pushed forward synchronously. At this time, the upper moving wheel 23 rolls on the upper moving rail 14. When the concave wiping cloth 28 approaches the elongated mold core 4 on the lower mold 2 of the wing, the upper moving wheel 23 just rolls to the end slope of the upper moving rail 14. At this time, under the action of the lower moving spring 26, the upper moving wheel 23 will roll against the end slope of the upper moving rail 14, thereby causing the concave wiping cloth 28 to move downward. When the lowered concave wiping cloth 28 wraps around the outside of the elongated mold core 4, the upper moving wheel 23 is just aligned with the upper moving rail. 14. Separation: At this point, the advancing concave wiping cloth 28 will wipe the surface of the elongated mold core 4 and the corners of the elongated mold core 4 and the lower wing mold 2. When the advancing arc-shaped wiping cloth 16 is about to approach the end of the cavity, the tube shaft 36 is just close to the square groove 3. At the same time, the pressure roller 30 is just in contact with the inclined pressure frame 6 and rolls along the lower inclined surface of the inclined pressure frame 6, allowing the sliding sleeve 19 to slide down on the carrier sleeve 20, thereby driving the tube shaft 36 down. When the arc-shaped wiping cloth 16 advances to the end of the cavity, the downward-moving tube shaft 36 just moves to the center position of the square groove 3. At the same time, the flat wiping cloth 46 on the tube shaft 36 presses against the inner bottom surface of the square groove 3 and the curved wiping cloth. 45 is pressed against the edge of the square groove 3. At this time, the advancement stops. Then, the servo motor 9 works to drive the flat wiping cloth 46 and the curved wiping cloth 45 on the tube shaft 36 to rotate. The rotating flat wiping cloth 46 wipes the inner bottom surface of the square groove 3. At the same time, the limiting wheel 41, under the push of the top spring 44, will roll along the inner wall of the square frame 37, allowing the rotating curved wiping cloth 45 to move in a square trajectory, that is, along the edge of the square groove 3, to wipe the corner of the edge of the square groove 3. This reduces the dead corners of the release agent wiping and ensures the demolding effect after molding. Then, the lower wing mold 2 and the upper wing mold 5 can be used to process and shape the wing.
