Description

Technical Field

[0001] This utility model relates to the technical field of mold repair for stretch molds, and in particular to an auxiliary device for mold repair of stretch molds. Background Technology

[0002] A drawing die is a type of mold used for drawing metal sheets. It can stretch metal sheets into various complex shapes, such as L-shaped, U-shaped, and T-shaped. This type of die is widely used in the aerospace field for the manufacture of aircraft skin.

[0003] The forming mold mainly consists of an upper mold body and a lower mold body. Both mold bodies have stepped templates on their backs. Before manufacturing the skin, the mold surface of the forming mold needs to be repaired. In the existing technology, when repairing the mold surface of the forming mold, it is necessary to use a crane or other lifting tools to lift the upper mold body of the forming mold, and then adjust the position of the mold body by flipping it. After the adjustment is completed, the mold repair personnel repair the mold from the bottom of the mold body, or place the forming mold on a support frame and then the mold repair personnel repair the mold from one side. During this process, in order to prevent the forming mold from falling, the crane needs to be connected to the forming mold at all times, which makes the mold repair work a significant safety hazard. Furthermore, since the lifting and flipping of the mold body using cranes and other tools requires constant adjustment according to the lifting height on site, it will consume a lot of time and ultimately result in low mold repair efficiency.

[0004] Therefore, there is an urgent need for a flipping device that can achieve high lifting height and flipping efficiency of the mold while minimizing safety risks. Utility Model Content

[0052] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0053] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0054] In the description of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0055] Furthermore, the terms "first," "second," and "third" are used only for distinguishing descriptions and should not be interpreted as indicating or implying relative importance.

[0056] Furthermore, the use of terms such as "horizontal," "vertical," and "suspended" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0057] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0058] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0059] It should be understood that before manufacturing the skin, the mold surface of the drawing die needs to be repaired. In the existing technology, when repairing the mold surface of the drawing die, it is necessary to use a crane or other lifting tools to lift the upper mold body 21 of the drawing die, and then adjust the position of the mold body by flipping it. After the adjustment is completed, the mold repair personnel repair the mold from the bottom of the mold body, or place the drawing die on a support frame and then the mold repair personnel repair the mold from one side. During this process, in order to prevent the drawing die from falling, the crane needs to be connected to the drawing die at all times, which makes the mold repair work a significant safety hazard. Furthermore, since the lifting and flipping of the mold body using cranes and other tools needs to be adjusted according to the lifting height on site, it will take a lot of time, ultimately resulting in low mold repair efficiency.

[0060] To address the aforementioned problems, this embodiment provides a die repair auxiliary device for drawing dies, such as... Figure 1 and Figure 2 As shown, it mainly includes a base 1, a transfer platform 2, a load-bearing frame 3, a lifting frame 4, and a tilting frame 6. This device is mainly used to lift and tilt the upper mold body 21 during mold repair, and to reduce safety hazards during mold repair.

[0061] In this embodiment, the base 1 adopts a rectangular structure, and in order to facilitate the installation of other components, the base 1 adopts a frame structure.

[0062] Among them, such as Figure 4 and 5 As shown, the upper surface of the rectangular body is provided with multiple transfer slide rails 11. The multiple transfer slide rails 11 are spaced apart and face the same direction. Specifically, the multiple slide rails are parallel to the long side of the base 1. In order to avoid the influence of dust on the slide rails, the upper surface of the base 1 is provided with multiple removable cover plates 14. The multiple removable cover plates 14 can be directly covered on the upper side of the base 1 to block dust and provide a stable flat surface for personnel to stand on when repairing the mold later.

[0063] In this embodiment, as Figures 1-8As shown, a transfer platform 2 is provided on the upper side of the base 1. The transfer platform 2 has a rectangular structure and its width is adapted to the base 1. The lower surface of the transfer platform 2 is provided with a transfer motor 21 and a transfer protrusion 22. A transfer screw seat 13 is provided inside the base 1, and the transfer screw seat 13 is located at the end of the base 1 away from the initial position of the transfer platform 2. The transfer motor 21 is located away from the transfer screw seat 13. A transfer screw 12 is provided inside the base 1, and one end of the transfer screw 12 is rotatably connected to the transfer screw seat 13. One end of the transfer screw 12 passes through the transfer protrusion 22 and is connected to the transfer motor 21. The axial direction of the transfer screw 12 is consistent with the laying direction of the transfer slide rail 11. The transfer screw 12 and the transfer protrusion 22 are slidably connected. The axis of the transfer screw 12 is located in the same plane as the center line of the base plate and the transfer platform 2, so that the transfer motor 21 drives the transfer screw 12 to rotate, thereby rotating relative to the transfer protrusion 22, and thus driving the transfer protrusion 22 and the transfer platform 2 to move along the slide rail or the axial direction of the transfer screw 12.

[0064] In this embodiment, as Figure 5 As shown, the rail body of the transfer slide rail 11 is fitted with two transfer sliders 15. The transfer sliders 15 can be displaced relative to the transfer slide rail 11, and the two transfer sliders 15 are spaced apart. The two transfer sliders 15 respectively set on the multiple transfer slide rails 11 are connected to the lower surface of the transfer platform 2, so that the transfer platform 2 can be stably displaced along the transfer slide rail 11.

[0065] The support frame 3 is located on one side of the base 1, and the extension direction of the transfer slide rail 11 is toward the support frame 3, thereby causing the transfer platform 2 to move toward the support frame 3.

[0066] The lifting frame 4 is located on the side of the bearing frame 3 facing the displacement platform. Both sides of the lifting frame 4 are provided with lifting screws 5 in the vertical direction, and the two ends of the lifting frame 4 are slidably connected to the two lifting screws 5 respectively. The two lifting screws 5 drive the lifting frame 4 to rise and fall in the vertical direction.

[0067] Among them, such as Figure 1 and 3 As shown, the device also includes a motor assembly 8, and both lifting screws 5 are connected to the motor assembly 8, thereby enabling the motor assembly 8 to drive the two lifting screws 5 to rotate simultaneously.

[0068] like Figure 1 , Figure 2 , Figure 9 and Figure 12As shown, the surface of the supporting frame 3 facing the lifting frame 4 is provided with two diagonal braces 31, which are arranged opposite each other on both sides of the flipping frame 6. The upper end of the diagonal brace 31 is provided with a lead screw bearing 32. The end faces of both sides of the lifting frame 4 are provided with lifting blocks 43. The two lifting blocks 43 are respectively arranged on the lower side of the two lead screw bearings 32. Specifically, the two lifting blocks 43 are provided with lead screw holes 431, and the two lead screw holes 431 are opened in the vertical direction. The lower surface of the lifting block 43 is provided with multiple threaded holes 432 for connection. The lifting lead screw 5 is fitted with a lifting base 511. The lifting base 511 is threadedly connected to the lifting lead screw 5, so that the lifting base 511 can rotate relative to the lifting lead screw 5 and can rise or fall.

[0069] In this embodiment, as Figures 9-12 As shown, two lifting bases 511 are respectively disposed on the lower side of two lifting blocks 43, and the upper surfaces of the two lifting bases 511 are respectively attached to and abut against the lower surfaces of the two lifting blocks 43. The two lifting bases 511 are respectively threadedly connected to the two lifting blocks 43 through threaded holes 432. One end of the two lifting screws 5 passes through the two screw bearings 32 and the two lifting blocks 43 in sequence, so that when the lifting screws 5 rotate and rise or fall relative to the lifting screws 5, the lifting frame 4 rises or falls, thereby driving the tilting frame 6 to move back to the vertical direction. The motor assembly 8 drives the lifting screws 5 to rotate.

[0070] In this embodiment, as Figure 2 , Figure 3 and Figure 9 As shown, the side of the supporting frame 3 facing the lifting frame 4 is provided with multiple lifting slide rails 33, and the multiple lifting slide rails 33 are laid in the vertical direction. For ease of description, in this embodiment, there are two lifting slide rails 33. The two lifting slide rails 33 are arranged in the vertical direction and are arranged opposite to each other on the side of the lifting frame 4. The two lifting slide rails 33 are respectively arranged on both sides of the side of the lifting frame 4 and extend along the axial direction of the lifting screw 5.

[0071] The lifting frame 4 is slidably connected to the surface of the supporting frame 3 and the two lifting slide rails 33. Specifically, each of the two lifting slide rails 33 is fitted with a plurality of lifting sliders 34, and the lifting sliders 34 are detachably connected to the surface of the lifting frame 4 facing the supporting frame 3. The plurality of lifting sliders 34 on the same lifting slide rail 33 are spaced apart in the vertical direction, and the lifting sliders 34 can move back and forth in the laying direction of the lifting slide rail 33, thereby making the lifting frame 4 move back and forth in the vertical direction stably.

[0072] The axial direction of the lifting screw 5 and the lifting slide rail 33 are both in the vertical direction.

[0073] The motor assembly 8 may be provided with a dust cover 10 or other structure to prevent dust from falling onto the surface of the motor assembly 8.

[0074] In this embodiment, as Figure 10 As shown, the motor assembly 8 includes a drive motor 81, a reducer 82, an intermediate commutator 83, and two end commutators 84. The drive motor 81 is connected to the reducer 82. One end of the reducer 82 is connected to one side of the intermediate commutator 83 via a drive shaft. The two end commutators 84 are positioned opposite each other on both sides of the intermediate commutator 83 and are connected to the two sides of the intermediate commutator 83 via a drive shaft. The two end commutators 84 are respectively connected to the lower ends of two lifting screws 5 via drive shafts, thereby driving the lifting screws 5 to rotate. The lifting screws 5 are arranged vertically, and one end is connected to one end of the drive shaft via a commutator. The connection method and direction of the end commutators 84, the intermediate commutator 83, and the drive shaft are all existing technologies and will not be described in detail.

[0075] In this embodiment, as Figure 1 , Figure 2 and Figure 11 As shown, the lifting frame 4 has connecting protrusions 41 on both ends. The two connecting protrusions 41 extend along the direction perpendicular to the surface of the lifting frame 4 and face the transfer platform 2. The flipping frame 6 is horizontally set on the upper side of the transfer platform 2, and its two ends are rotatably connected to the surfaces of the two connecting protrusions 41, so that the flipping frame 6 can be flipped relative to the connecting protrusions 41.

[0076] The flipping frame 6 has a rectangular structure, with its rear end facing the lifting frame 4 and its front end away from the lifting frame 4.

[0077] In this embodiment, as Figure 1 , Figure 2 and Figure 11 As shown, the upper end face of the connecting convex plate 41 is provided with a flip bearing seat 44, and one end of the rotating shaft 441 of the flip bearing seat 44 is connected to the flip frame 6, so that the flip frame 6 can rotate.

[0078] In this embodiment, as Figure 1 , Figure 2 , Figure 11 and Figure 12 As shown, a plurality of spaced electric pull rods 42 are provided between the upper surface of the flipping frame 6 and the side surface of the lifting frame 4 facing the transfer platform 2. The two ends of the electric pull rods 42 are rotatably connected to the upper surface of the flipping frame 6 and the side surface of the lifting frame 4, respectively. Specifically, for ease of description, in this embodiment, two electric pull rods 42 are used. One end of the two electric pull rods 42 is disposed opposite to the side of the lifting frame, and the other end is disposed opposite to the upper surface of the flipping frame 6, thereby causing the flipping frame 6 to rotate.

[0079] Among them, the electric pull rod 42 can be connected to the side of the lifting frame 4 and the side of the flipping frame 6 by means of hinge, base 1 plus pivot, etc.

[0080] Among them, the electric pull rod 42 can adopt a hydraulic cylinder, electric pull cylinder or other structure, and the drive end is set close to the lifting frame 4.

[0081] In this embodiment, the electric pull rod 42 extends or shortens to push or pull the flipping frame 6. The two ends of the flipping frame 6 are rotatably connected to two connecting protrusions 41 respectively. The electric pull rod 42 is rotatably connected to the flipping frame 6 and the lifting frame 4, so that the electric pull rod 42 drives the flipping frame 6 to flip. The flipping angle of the flipping frame 6 can be set according to the requirements. In this embodiment, the flipping frame 6 flips 90 degrees.

[0082] The rotation angle of the flipping frame 6 can be controlled according to the extension or shortening length of the electric pull rod 42, which is existing technology and will not be described in detail.

[0083] The transfer slide rail 11, the transfer screw 12, and the transfer screw seat 13 are all connected at one end and are located on the lower side of the flip frame 6, so that the transfer platform 2 can be moved to the lower side of the flip frame 6, thereby transferring the drawing die to the lower side of the flip frame 6.

[0084] like Figure 17 As shown, both the upper mold body 21 and the lower mold body 22 of the drawing die have stepped surfaces 23. In order to stably clamp and flip the upper mold body 21, in this embodiment, as follows... Figure 2 , Figure 13 , Figure 14 and Figure 15 As shown, the lower surface of the flipping frame 6 is provided with a clamping component 7 for clamping the pull mold 20, and is adapted to the upper mold body 21 of the pull mold. Specifically, the clamping component 7 includes a front clamping plate 71 and a rear clamping plate 72. When the flipping frame 6 is placed horizontally, both the front clamping plate 71 and the rear clamping plate 72 are placed horizontally.

[0085] In this embodiment, as Figure 1 , Figure 2 , Figure 11 , Figure 13 and Figure 15As shown, both ends of the flipping frame 6 are provided with front pull rods 73 and rear pull rods 74, and the front pull rods 73 and rear pull rods 74 on the same side face opposite directions. The front pull rods 73 and rear pull rods 74 are at the same height. The two front pull rods 73 are connected to the two ends of the front clamping plate 71, and the two rear pull rods 74 are connected to the two ends of the rear clamping plates 72. The lower side of the flipping frame 6 is provided with multiple spaced clamping slide rails 61. The front pull rods 73 and rear pull rods 74 are parallel to the clamping slide rails. When the flipping frame 6 is horizontal, the laying direction of the multiple clamping slide rails 61 is consistent with the laying direction of the transfer slide rail 11. The upper surfaces of the front clamping plate 71 and the rear clamping plate 72 are slidably disposed at the two ends of the multiple clamping slide rails 61, so that the front clamping plate 71 and the rear clamping plate 72 can be relatively displaced, thereby clamping the upper mold body 21.

[0086] The clamping slide rail 61 is fitted with two clamping sliders 62. Both clamping sliders 62 can slide relative to the clamping slide rail 61. The two clamping sliders 62 are connected to the upper surfaces of the front clamping plate 71 and the rear clamping plate 72, respectively. This allows the front clamping plate 71 and the rear clamping plate 72 to be positioned under the flipping frame 6 while also being able to move stably in opposite directions along the clamping slide rail 61.

[0087] In this embodiment, both ends of the upper surfaces of the front clamping plate 71 and the rear clamping plate 72 are provided with two oppositely arranged connecting lugs 75, and a connecting shaft 751 is provided between the two connecting lugs 75. One end of the front pull rod 73 and the rear pull rod 74 is provided with a ring head 76, which is adapted to the connecting shaft 751. The connecting shaft 751 between the two connecting lugs 75 of the front clamping plate 71 passes through the ring head 76 at one end of the two front pull rods 73, and the connecting shaft 751 between the two connecting lugs 75 of the rear clamping plate 72 passes through the ring head 76 at one end of the two front pull rods 73. The connecting shaft 751 between the ear plates 75 passes through the annular head 76 at one end of the two rear pull rods 74 respectively. The front pull rod 73 and the rear pull rod 74 are both fixedly installed on the flip frame 6, so that the front pull rod 73 and the rear pull rod 74 can pull the front clamping plate 71 and the rear clamping plate 72 by telescopic movement, thereby causing the front clamping plate 71 and the rear clamping plate 72 to move in opposite directions along the clamping slide rail 61, thereby adapting to the stepped layer of the upper mold body 21 of the drawing mold, and thus clamping the upper mold body 21 of the drawing mold.

[0088] Multiple clamping grooves 231 are provided on both sides of the stepped layer of the upper mold body 21 of the drawing die. The cross-sections of the multiple clamping grooves 231 in the vertical direction are all convex structures. In order to stably clamp the upper mold body 21 of the drawing die, in this embodiment, as shown in 13 and... Figure 15As shown, multiple lifting motors 30 are provided on the upper surfaces of the front clamping plate 71 and the rear clamping plate 72. The multiple lifting motors 30 are spaced apart along the direction of extension of the vertical clamping guide rail. Specifically, one end of each of the multiple lifting motors 30 is provided with a lifting rod 31. One end of the lifting rod 31 of the multiple lifting motors 30 passes through the plates of the front clamping plate 71 and the rear clamping plate 72 respectively, and is located on the lower side of the front clamping plate 71 and the rear clamping plate 72. Guide rods 32 are provided on both sides of the lifting motors 30. The guide rods 32 are parallel to the lifting rods 31, and the multiple guide rods 32 pass through the front clamping plate 71 or the rear clamping plate 72 respectively. The lower ends of the lifting rods 31 and the guide rods 32 are provided with convex plates 33. The multiple convex plates 33 are parallel to the front clamping plate 71 or the rear clamping plate 72 respectively. The smaller ends of the convex plates 33 are arranged facing each other and are adapted to the clamping groove 231 of the step layer of the drawing die, so that one end of the convex plate 33 can be inserted into the clamping groove 231 of the step layer.

[0089] In this embodiment, such as 13 and Figure 15 As shown, both the front clamping plate 71 and the rear clamping plate 72 have protruding plates 77 at their lower ends, and both protruding plates 77 are perpendicular to the lower surfaces of the front clamping plate 71 and the rear clamping plate 72. Multiple convex plates 33, respectively disposed on the front clamping plate 71 and the rear clamping plate 72, are respectively disposed on the outer sides of the two protruding plates 77. In this embodiment, when it is necessary to clamp the upper mold body 21, the upper mold body 21 is first transferred to the lower side of the flipping frame 6 via the transfer platform 2. Then, the flipping platform is lowered to a position approximately 2mm away from the upper surface of the step layer of the upper mold body 21 between the front clamping plate 71 and the rear clamping plate 72. Then, the front pull rod 73 and the rear pull rod... 74. Pull the front clamping plate 71 and the rear clamping plate 72 so that the front clamping plate 71 and the rear clamping plate 72 move towards each other, so that the facing surfaces of the two protruding plates 77 abut against the side surfaces of the step layer of the upper mold body 21. At this time, one end of the multiple protruding plates 33 located on both sides of the step layer is inserted into the clamping groove 231 of the step layer of the upper mold body 21. Then, the lifting motor 30 drives the lifting rod 31 to move upward, which in turn drives the guide rod 32 and the protruding plates 33 to move upward, so that the upper surface of the protruding plate 33 abuts against the upper inner wall of the clamping groove 231, thereby stably clamping the upper mold body 21.

[0090] In this embodiment, the lifting motor 30 enables the device to adapt to step layers of different thicknesses while also applying force to stably clamp the upper mold body 21 with multiple convex plates 33. At the same time, the upper mold body 21 is clamped from different directions by the front clamping plate 71 and the rear clamping plate 72, thereby making the clamping of the upper mold body 21 more stable.

[0091] Among them, multiple convex plates 33 are parallel to the lower surfaces of the front clamping plate 71 and the rear clamping plate 72, respectively.

[0092] In some embodiments, such as Figure 4 , such as 7 and Figure 8As shown, a rotating platform 9 is provided on the upper side of the transfer platform 2. Multiple bullseye wheels 91 are provided between the transfer platform 2 and the rotating platform 9. The multiple bullseye wheels 91 are arranged sequentially at intervals on the upper surface of the transfer platform 2 and abut against the lower surface of the rotating platform 9. The device also includes a side rotating screw 23. A side support block 24 is provided on one side end surface of the transfer platform 2. A side screw seat 25 is provided on the upper surface of the side support block 24. One end of the side rotating screw 23 passes through the side screw seat 25 and is connected to the side end of the rotating platform 9, thereby pushing the rotating platform 9 to move axially toward the side rotating screw 23.

[0093] In this embodiment, as Figure 4 , such as 7 and Figure 8 As shown, the device also includes a front rotating lead screw 26, a front support block 27 on the front surface of the transfer platform 2, a front lead screw seat 28 on the upper surface of the front support block 27, one end of the front rotating lead screw 26 passing through the front lead screw seat 28, one end of the front rotating lead screw 26 and one end of the side rotating lead screw 23 being rotatably connected to the front and side end faces of the rotating platform 9 respectively, and the axis of rotation is in the vertical direction. A bearing seat 29 is provided on the upper surface of the front lead screw seat 28, and the front lead screw seat 28 and the bearing seat 29 are rotatably connected. Thus, when it is necessary to adjust the position of the drawing mold 20, the side rotating lead screw 23 and the front rotating lead screw 26 can be turned at the same time, thereby causing the turntable to rotate on the transfer platform 2, thereby adjusting the position of the drawing mold. Thus, when the transfer platform 2 transfers the drawing mold to the lower side of the flipping frame 6, the drawing mold is located on the lower side of the clamping assembly on the lower side of the flipping frame 6, thereby allowing the clamping assembly to easily clamp the upper mold body 21 of the drawing mold.

[0094] In this embodiment, as Figure 4 , such as 7 and Figure 8 As shown, the upper surface of the rotating platform 9 is provided with a plurality of spaced fixing holes 92, and the fixing holes 92 are provided with internal threads. The device also includes a plurality of machine tool clamping plates 40. For ease of description, the number of machine tool clamping plates 40 is eight. The machine tool clamping plates 40 are provided with a groove 41 in the center. In this embodiment, when the lower mold body 22 is placed on the upper surface of the rotating platform 9, the eight machine tool clamping plates 40 are respectively inserted into the clamping grooves 231 of the step layer of the lower mold body 22. Then, bolts are inserted into the grooves 41 of the machine tool clamping plates 40 and threadedly connected to the fixing holes 92 of the transfer platform 2, thereby stably fixing the machine tool clamping plates 40 to the transfer platform 2, and simultaneously limiting and fixing the drawing die, so that the drawing die is relatively stable when the transfer platform 2 is displaced.

[0095] The length of the machine tool clamping plate 40 and the length of the groove 41 can be set according to requirements, so that after one end of the machine tool clamping plate 40 is inserted into the clamping groove 231, a bolt can be easily inserted into the other end.

[0096] In this embodiment, a perimeter fence 50 is also provided around the device to prevent personnel from accidentally entering.

[0097] In this embodiment, the device is also equipped with an industrial control computer 60 and multiple sensors, including detection components such as probes, limit switches, and ultrasonic sensors, which are used to control and detect the displacement, flipping, or extension and retraction of related structures in the device, such as the displacement or rotation of the transfer platform 2, lifting frame 4, flipping frame 6, front clamping plate 71, and rear clamping plate 72. Since these are all existing technologies, they will not be described in detail in this embodiment.

[0098] In this embodiment, when mold repair work of the drawing die is required, the drawing die is first placed on the rotating platform 9 on the upper side of the transfer platform 2 for limiting and fixing. Then, the position is adjusted by the front rotating screw 26 and the side rotating screw 23. After that, the transfer platform 2 moves the drawing die to the lower side of the flipping frame 6. Then, the lifting screw 5 rotates, driving the lifting frame 4 to descend, thereby causing the flipping frame 6 to be lowered. When the lower surfaces of the front clamping plate 71 and the rear clamping plate 72 are displaced to the upper surface of the step layer of the upper mold body 21 of the drawing die, the displacement of the lifting frame 4 is stopped. Then, the front pull rod 73 and the rear pull rod 74 pull the front clamping plate 71 and the rear clamping plate 72 respectively, causing them to move towards each other, thereby causing the front clamping plate 71 to... The surface of the lower convex plate 77 of the rear clamping plate 72 abuts against the end faces of both sides of the stepped layer of the upper mold body 21. At the same time, one end of the convex plate 33 is inserted into the clamping groove 231 of the stepped layer of the upper mold body 21. Then, the lifting motor 30 drives the convex plate 33 to move upward and clamp the upper mold body 21 of the pull mold 20. Finally, the lifting frame 4 moves upward and separates the upper mold body 21 from the lower mold body 22. After the upper mold body 21 moves to the preset height, the two electric pull rods 42 pull the flipping frame 6. The two ends of the flipping frame 6 are connected to the convex plate 41 and rotate. The flipping frame 6 rotates so that the mold surface of the upper mold body 21 is horizontal to one side, so that personnel can repair the mold on one side of the upper mold body 21.

[0099] When the upper mold body 21 and the lower mold body 22 are separated, the transfer platform 2 is moved to the initial position, and then the lower mold body 22 can be repaired.
