[0018] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0019] Example: like Figure 1-5 As shown, this embodiment provides a rapid mold changing device for an automobile structural part mold, comprising a carrying plate 1, a carrying frame 2 and a vertical plate 3 are fixedly mounted on the upper end surface of the carrying plate 1, a driving groove 4 is provided through a groove in the middle of the carrying frame 2, a rotating rod 5 is provided on the side walls of both sides of the carrying frame 2 and is rotatably connected to a clamping plate 7 through the rotating rod 5, and a driving hole 8 is provided through an opening on the clamping plate 7; The side walls of the carrying frame 2 are provided with a through hole 6, a driving rod 9 is slidably connected in the hole 6, and a driving plate 10 is integrally provided at one end of the driving rod 9 close to the clamping plate 7; The bottom of the carrier frame 2 is penetrated by an opening and a hook spring 11 is arranged in the hole, and the two ends of the hook spring 11 are respectively hooked with the bottom of the two clamping plates 7; A mold part 13 is placed on the upper end surface of the carrying frame 2 , a hydraulic cylinder 14 is mounted on the vertical plate 3 , and a driving block 15 is fixedly mounted on the output end of the hydraulic cylinder 14 .

[0020] In a specific application scenario, the hook spring 11 pulls the bottom of the clamping plates 7 hooked at both ends through its own elastic force, so that the turning parts at the top of the two clamping plates 7 are in an expanded state, for the base of the mold part 13 to be placed in, and is vertically inserted through the guide column 12 to keep the mold part 13 stably placed. The "V"-shaped driving block 15 respectively contacts the round head ends of the two driving rods 9 through the inclined surfaces on both sides, and slides and drives the driving rods 9, so that the turning parts at the top of the two clamping plates 7 are rotated to move closer to each other, and then the base at the bottom of the mold part 13 is clamped and fixed to complete the installation of the mold part 13; when changing the mold, the hydraulic cylinder 14 drives the driving block 15 to slide out of the driving groove 4 through the output end, releases the sliding drive of the driving rod 9, and makes the bottom of the clamping plate 7 move closer to each other under the elastic action of the hook spring 11, driving the turning parts at the top of the two clamping plates 7 to reset to the expanded state to wait for the installation of the next mold part 13, thereby completing the rapid mold change operation of the mold part 13. The rapid mold changing device for an automobile structural part mold of the present invention is further described below in conjunction with the application scenario.

[0021] For more details, see Figure 1-5 A base is provided at the bottom of the mold part 13, and a turning arrangement is provided at the top of the clamping plate 7 to clamp the base of the mold part 13 by rotating.

[0022] In this embodiment, since the mold part 13 needs to undergo different processes such as stamping and casting after bearing loads during the automobile manufacturing process, in order to maintain the stability of the mold part 13 and prevent the mold part 13 from shifting in subsequent construction processes such as stamping and casting, when the rapid mold changing device performs a mold changing operation, a clamping plate 7 is provided with a turning point at the top end and the base of the mold part 13 is clamped by rotation, thereby providing sufficient clamping force to firmly fix the mold part 13 on the construction, maintain the stability of subsequent construction, and thereby avoid improper installation of automobile structural parts, avoid damage to the mold part 13 or the product, and reduce the risk of causing safety accidents.

[0023] More preferably, referring to Figure 1-5 The driving plates 10 are arranged in pairs and are respectively located on both sides of the clamping plate 7, and a gap is reserved between the driving plates 10 and the two sides of the clamping plate 7.

[0024] In this embodiment, during the mold changing operation of the quick mold changing device, since it is necessary to push the clamping plate 7 through the driving rod 9 so that the clamping plate 7 rotates with the rotating rod 5 as a fulcrum to realize the clamping and fixing function, an integrated driving plate 10 is provided on the driving rod 9 so that the clamping plate 7 can be pushed by the driving plate 10 during the sliding of the driving rod 9. In order to avoid the small distance between the paired driving plates 10, which may interfere with the surface of the clamping plate 7 and affect the rotation of the clamping plate 7, a reserved gap is provided between the driving plate 10 and both sides of the clamping plate 7 to facilitate the rotation of the clamping plate 7, keep the rotation and clamping of the clamping plate 7 smooth, and thus keep the mold changing operation stable.

[0025] More preferably, referring to Figure 1-5 A guide column 12 is fixedly mounted on the upper end surface of the carrying frame 2 , and a guide groove matched with the guide column 12 is opened on the base of the mold member 13 .

[0026] In this embodiment, during the mold changing operation of the quick mold changing device, in order to enable the replaced mold part 13 to be quickly and stably placed on the upper end surface of the supporting frame 2, two guide columns 12 are fixedly installed on the upper end surface of the supporting frame 2, and the guide columns 12 are adapted to the bottom of the mold part 13, so that the mold part 13 can be vertically inserted and the mold part 13 can be limited in the horizontal direction to prevent the mold part 13 from shifting and shaking, thereby keeping the mold part 13 stably placed.

[0027] Furthermore, refer to Figure 1-5 The driving block 15 is matched with the driving groove 4 and inserted into the driving groove 4 to slide.

[0028] In this embodiment, during the mold changing operation of the quick mold changing device, the hook spring 11 pulls the bottom of the clamping plates 7 hooked at both ends through its own elastic force, so that the two clamping plates 7 rotate as a whole with the rotating rod 5 as the fulcrum, so that the turning parts at the top of the two clamping plates 7 are in an unfolded state. In order to clamp and fix the mold part 13 after it is placed, a driving block 15 is provided to adapt to the driving groove 4 and is inserted into the driving groove 4 to slide, so that the driving rod 9 is driven by the driving block 15 to keep the clamping stable.

[0029] Furthermore, refer to Figure 1-5 The driving block 15 is arranged in a "V" shape with inclined surfaces on both sides. The end of the driving rod 9 close to the driving groove 4 is arranged in a round head and maintains a sliding connection with the inclined surface of the driving block 15.

[0030] In this embodiment, during the mold changing operation of the quick mold changing device, when the driving block 15 is driven by the output end of the hydraulic cylinder 14 to advance, the "V"-shaped driving block 15 respectively contacts the round head ends of the two driving rods 9 through the inclined surfaces on both sides thereof, and as the driving block 15 is continuously advanced, the round head ends of the two driving rods 9 are squeezed out, so that the two driving rods 9 slide out of the insertion holes 6 on both sides of the driving groove 4 respectively. When the driving rod 9 slides out, it also drives the driving plate 10 at the other end to move synchronously, so that the driving plate 10 contacts the surface of the clamping plate 7 to push the bottom of the clamping plate 7, and then drives the clamping plate 7 as a whole to rotate with the rotating rod 5 as the fulcrum, so that the turning parts at the top of the two clamping plates 7 are brought closer to each other through rotation, and then the base at the bottom of the mold part 13 is clamped and fixed, and the installation of the mold part 13 is completed.

[0031] More specifically, see Figure 1-5 The diameter of the insertion hole 6 is larger than the diameter of the driving rod 9 and a clearance for movement is reserved.

[0032] In this embodiment, during the mold changing operation of the quick mold changing device, since the rotational clamping of the clamping plate 7 needs to be carried out through a rotational connection with the rotating rod 5, the clamping plate 7 will drive the bottom of the clamping plate 7 to rotate synchronously during the rotation, which will cause the driving hole 8 to move with the rotation of the bottom of the clamping plate 7. In order to prevent the driving rod 9 that maintains a sliding connection with the driving hole 8 from interfering with the rotation of the clamping plate 7 in turn, the aperture of the jack 6 is set to be larger than the diameter of the driving rod 9 and a movable gap is reserved, so that the clamping plate 7 can rotate through the reserved movable gap during rotation without affecting the contact and push between the driving plate 10 and the surface of the clamping plate 7, thereby avoiding motion interference between the clamping plate 7 and the driving rod 9 and maintaining smooth rotation clamping of the clamping plate 7.

[0033] More specifically, see Figure 1-5 The clamping plate 7 is flat as a whole.

[0034] In this embodiment, during the mold changing operation of the rapid mold changing device, in order to improve the clamping effect of the clamping plate 7 on the base of the mold part 13, the clamping plate 7 is set to be flat as a whole, and the contact area between the clamping plate 7 and the base of the mold part 13 is increased, thereby maintaining the stability of the mold part 13, improving the adaptability after the mold changing operation and the stability in the subsequent processing technology.

[0035] More specifically, see Figure 1-5 , the sliding distance of the driving block 15 in the driving groove 4 is less than the length of the driving block 15 .

[0036] In this embodiment, during the process of the rapid mold changing device performing mold changing operation, the excessive sliding of the driving block 15 in the driving groove 4 will cause the driving block 15 to separate from the end of the driving rod 9, and after the driving block 15 slides, the driving rod 9 will move towards each other under the elastic force of the hook spring 11, thereby blocking the rear end of the driving block 15 and blocking the reset channel of the driving block 15. As a result, the rapid mold changing device cannot perform repeated operations, so the sliding distance of the driving block 15 in the driving groove 4 is set to be smaller than the length of the driving block 15, so that the driving block 15 will not separate from the end of the driving rod 9 due to excessive sliding, and the sliding connection between the driving block 15 and the end of the driving rod 9 is kept stable and convenient for repeated use, thereby improving the practicality of the rapid mold changing device.

[0037] More specifically, see Figure 1-5 , the two driving rods 9 are arranged opposite to each other, and the driving block 15 slides in the middle of the driving groove 4.

[0038] In this embodiment, during the mold changing operation of the quick mold changing device, in order to keep the sliding distance of the driving rods 9 on both sides of the supporting frame 2 consistent, thereby forming a synchronous drive of the clamping plates 7 and maintaining the stability of the opposite clamping of the two clamping plates 7, the two driving rods 9 are arranged opposite to each other, and the driving block 15 slides in the middle of the driving groove 4, so that the "V"-shaped inclined surface of the driving block 15 is consistent with the distance between the two driving rods 9, thereby maintaining the consistency of the push on the two driving rods 9 through the interference of the inclined surfaces.

[0039] Working principle: In the quick mold-changing device for automobile structural parts mold of the present invention, during the process of installing the mold part 13, the hook spring 11 pulls the bottom of the clamping plate 7 hooked at both ends by its own elastic force, so that the two clamping plates 7 are rotated as a whole with the rotating rod 5 as the fulcrum, so that the turning parts at the top of the two clamping plates 7 are in an unfolded state, so that the base of the mold part 13 is placed, and the mold part 13 is vertically inserted through the guide column 12 to keep the mold part 13 placed stably; Then the hydraulic cylinder 14 is started to work, and the hydraulic cylinder 14 then drives the driving block 15 to advance in the driving groove 4 through the output end. During the advancement of the driving block 15, the "V"-shaped driving block 15 respectively contacts the round head ends of the two driving rods 9 through the inclined surfaces on both sides thereof, and as the driving block 15 continues to advance, the round head ends of the two driving rods 9 are squeezed out, so that the two driving rods 9 slide out of the jacks 6 on both sides of the driving groove 4, respectively. When the driving rod 9 slides out, it also drives the driving plate 10 at the other end to move synchronously, so that the driving plate 10 contacts the surface of the clamping plate 7 to push the bottom of the clamping plate 7, and then drives the clamping plate 7 as a whole to rotate with the rotating rod 5 as the fulcrum, so that the turning parts at the top of the two clamping plates 7 are brought closer to each other through rotation, and then the base at the bottom of the mold part 13 is clamped and fixed, and the installation of the mold part 13 is completed; When the mold needs to be changed, the hydraulic cylinder 14 drives the driving block 15 to slide out of the driving groove 4 through the output end, so that as the driving block 15 withdraws, the inclined surfaces on both sides of the driving block 15 are disengaged from the round head end of the driving rod 9, thereby releasing the sliding drive of the driving rod 9, so that the bottom of the clamping plate 7 moves towards each other under the elastic action of the hook spring 11, driving the turning part at the top of the two clamping plates 7 to reset to the expanded state, waiting for the installation of the next mold part 13, thereby completing the rapid mold change operation of the mold part 13.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
