[0022] The technical effects achieved by the present invention are:

[0023] The first rotating mechanism and the second rotating mechanism of the present invention are arranged such that the first rotating shaft rotates to drive the first worm to rotate, the first worm cooperates with the first worm wheel to drive the first gear on the second rotating shaft to rotate, the first gear meshes with the tooth column, so that the first gear rotates around the tooth column and drives the mounting plate to rotate left and right, thereby adjusting the left and right position of the clamped mold; when the first limiting shaft rotates, the second worm drives the second worm wheel to rotate, the second worm wheel drives the third worm on the third rotating shaft to rotate, the third worm meshes with the third worm wheel to drive the mounting shaft to rotate, and the clamped mold can be adjusted to rotate up and down, thereby improving the flexibility of mold welding, meeting the welding requirements of different angles, and improving the welding quality.

[0024] The setting of the linkage adjustment mechanism of the present invention realizes the power supply to the first rotating mechanism, the clamping mechanism and the second rotating mechanism through the cooperation of a rotating motor, the second hydraulic cylinder and the adjusting plate. Only one rotating motor is used to meet the power requirements of multiple working mechanisms. Compared with the traditional multi-motor driving method, the number of motors used is greatly reduced, which not only reduces the manufacturing cost of the equipment, but also significantly reduces the total energy consumption of the equipment during operation due to the reduction in the number of motors.

[0025] The flexible clamping claw mechanism of the present invention is arranged with push rods distributed in an array on the box body, and the rubber push blocks at the front end thereof will first contact the mold surface in all directions. As the clamping action proceeds, each rubber push block independently produces deformation according to the contour characteristics of the mold surface, so as to achieve preliminary adaptation to the complex shape of the mold. In this process, after all the rubber push blocks are fully fitted with the mold, the internal trigger mechanism is started, and through ingenious circuit control, the electromagnet is energized to generate magnetic force, and the card plate is driven to move up to firmly lock each push rod; at this time, the locked push rod array has perfectly adapted to the outer contour of the mold, forming a stable contact relationship, and then, the support plate moves smoothly under the drive of the power mechanism, further tightening the clamping force on the mold, relying on the precise displacement of the support plate and the coordinated action of the push rod array that has been adapted and locked to the mold, a uniform clamping force distribution is achieved, ensuring all-round and stable clamping of the special-shaped mold, and ensuring that the mold will not be displaced or shaken in the subsequent welding process.

[0039] In order to make the purpose and advantages of the present invention clearer, the present invention will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present invention, and does not strictly limit the specific protection scope claimed by the present invention.

[0040] As Figures 1 - 3 shown, a welding fixture for mold manufacturing includes a base 1, a mounting plate 2 is arranged above the base 1, and a first rotating mechanism 3 for driving the mold to rotate left and right is arranged on the top of the base 1; the first rotating mechanism 3 includes a tooth column 31 fixed in the middle of the top of the base 1, the top of the tooth column 31 is rotatably connected to the bottom of the mounting plate 2, a first rotating shaft 32 is arranged on one side of the bottom of the mounting plate 2, a first worm 33 is fixed at one end of the first rotating shaft 32, a second rotating shaft 34 is arranged on the bottom of the mounting plate 2 and on one side of the first worm 33, a first worm gear 35 meshing with the first worm 33 is fixed on the outer wall of the second rotating shaft 34, and a first gear 36 meshing with the tooth column 31 is fixed at the bottom of the second rotating shaft 34.

[0041] According to the above structure, when the first rotating shaft 32 rotates, it drives the first worm 33 to rotate. The first worm 33 drives the first worm gear 35 to rotate. The first worm gear 35 drives the first gear 36 to rotate through the second rotating shaft 34. The first gear 36 meshes with the tooth column 31, causing the first gear 36 to rotate around the tooth column 31 and driving the mounting plate 2 to rotate left and right. Furthermore, the left and right positions of the clamped mold are adjusted, improving the flexibility of mold welding. The cooperation of the first worm gear 35 and the first worm 33 is set to lock the second rotating shaft 34 when the rotation of the first rotating shaft 32 stops, avoiding the rotation of the mounting plate 2 during operation.

[0042] As Figures 1 - 2 shown, a clamping mechanism 4 is provided at the top of the mounting plate 2; the clamping mechanism 4 includes two moving grooves 41 opened at the top of the mounting plate 2. A double-headed screw rod 43 is arranged between the interiors of the two moving grooves 41. Moving blocks 42 are threadedly connected to the outer wall of the double-headed screw rod 43 and are located within the moving grooves 41. Support plates 44 are fixed to the tops of the moving blocks 42. Mounting shafts 45 are symmetrically and rotatably installed through the outer walls of the two support plates 44.

[0043] A second rotating mechanism 5 for driving the mold to rotate up and down is provided on the clamping mechanism 4. The second rotating mechanism 5 includes a third worm gear 57 fixed to one end of the mounting shaft 45. A third rotating shaft 54 is arranged on one side of the support plate 44. A third worm 56 meshing with the third worm gear 57 is arranged at the top end of the third rotating shaft 54. A second worm gear 55 is arranged at the bottom end of the third rotating shaft 54. A first bushing 52 is arranged through the outer wall of the support plate 44 and is located on one side of the second worm gear 55. A second worm 53 meshing with the second worm gear 55 is arranged on the outer wall of the first bushing 52. A first limiting groove is arranged inside the first bushing 52. A first limiting shaft rod 51 is slidably installed between the interiors of the two first limiting grooves. A support ear rotatably connected to the first limiting shaft rod 51 is fixed to the top of the mounting plate 2.

[0044] According to the above structure, when the double-headed lead screw 43 rotates, it drives the two moving blocks 42 to move synchronously. The moving block 42 drives the support plates 44 to move relative to each other. The support plates 44 drive the flexible jaw mechanism 6 on the mounting shaft 45 to move relative to each other, thereby completing the stable clamping of the mold. When the first limit shaft rod 51 rotates, it drives the second worm 53 to rotate. The second worm 53 drives the second worm gear 55 to rotate. The second worm gear 55 drives the third worm 56 on the third rotating shaft 54 to rotate. The third worm 56 meshes with the third worm gear 57 to drive the mounting shaft 45 to rotate, which can adjust the up and down rotation of the clamped mold, further improving the flexibility of mold welding. The cooperation of the first bushing 52 and the first limit shaft rod 51 is set. When the support plate 44 moves, it can drive the first bushing 52 to move on the first limit shaft rod 51, avoiding affecting the normal movement of the support plate 44 and improving the perfection of the equipment. The setting of the first limit shaft rod 51 can drive the second worm 53 on the two first bushings 52 to rotate synchronously, improving the stability of the equipment operation. The third worm gear 57 and the third worm 56 are set. When the mounting shaft 45 stops, it can lock the mounting shaft 45, improving the stability of mold clamping.

[0045] As Figures 4 - 8 shown, a flexible jaw mechanism 6 for clamping special-shaped molds is provided on the clamping mechanism 4. The flexible jaw mechanism 6 includes boxes 61 fixed to opposite ends of two mounting shafts 45. A plurality of first insertion holes 62 are equidistantly arranged in an array on the outer walls of opposite sides of the two boxes 61. A push rod 63 is inserted into the first insertion hole 62. A plurality of anti-slip lines are equidistantly arranged at the bottom of the push rod 63. The other end of the push rod 63 is fixed with a first mounting plate 64 inside the box 61. A second insertion hole 65 is opened on one side of the first mounting plate 64, and the second insertion hole 65 extends into the push rod 63. First conductive contacts 66 electrically connected to each other through wires are arranged on the outer wall of the first mounting plate 64 and on both sides of the second insertion hole 65. A third insertion rod 610 is inserted into the second insertion hole 65. One end of the third insertion rod 610 is fixed with a second mounting plate 68 outside the second insertion hole 65. A second spring 611 is sleeved on the outer wall of the third insertion rod 610 between the first mounting plate 64 and the second mounting plate 68. Two second conductive contacts 612 cooperating with the first conductive contacts 66 are arranged on one side of the second mounting plate 68. The second conductive contacts 612 on adjacent second mounting plates 68 are electrically connected in series with each other. A second insertion rod 67 is fixed to the other side of the second mounting plate 68. A guide hole slidably connected to the second insertion rod 67 is opened inside the box 61. A first spring 69 is arranged on the outer wall of the second insertion rod 67 and on one side of the second mounting plate 68, and both ends of the first spring 69 are in contact with the inner side of the box 61 and the outer side of the second mounting plate 68 respectively;

[0046] One end of the ejector rod 63 extends outside the first insertion hole 62 and is provided with a rubber ejecting block 620. An installation cavity is arranged inside the rubber ejecting block 620. A conductive sheet 622 is arranged on the inner side of the installation cavity. Two third conductive contact blocks 623 cooperating with the conductive sheet 622 are arranged on the other inner side of the installation cavity. The third conductive contact blocks 623 and the second conductive contact blocks 612 are electrically connected in series through wires. A fifth spring 621 is arranged inside the installation cavity.

[0047] Installation ears 613 are fixed on both sides inside the box body 61. A connecting rod 614 is slidably installed through the outer wall of the installation ear 613. A clamping plate 615 for locking the ejector rod 63 is fixed between the outer walls of the two connecting rods 614. The clamping plate 615 is arc-shaped at the lower part of the ejector rod 63. A third spring 616 connected to the clamping plate 615 is fixed at the bottom of the installation ear 613. A connecting rod 614 is fixed between the tops of the two connecting rods 614. An electromagnet 618 is fixed at the top of the connecting rod 614. An iron plate 619 cooperating with the electromagnet 618 is arranged above the electromagnet 618 on the inner side of the box body 61.

[0048] According to the above structure, when clamping the mold, place the mold between the two box bodies 61. By moving the two support plates 44 closer to each other, the box bodies 61 on the mounting shafts 45 are driven to move. During the movement, the rubber ejecting block 620 contacts the mold first. As the box body 61 continues to move, since there is a cavity inside the rubber ejecting block 620, when being squeezed, the rubber ejecting block 620 is compressed, causing the conductive sheet 622 inside to contact the two third conductive contact blocks 623. At the same time, the rubber ejecting block 620 pushes the ejector rod 63 to move. The ejector rod 63 drives the first conductive contact block 66 on one side of the first mounting plate 64 to move, making the first conductive contact block 66 contact the opposite second conductive contact block 612. Then continue to move the box body 61 until all the rubber ejecting blocks 620 contact the mold. At the same time, all the first conductive contact blocks 66 on the first mounting plates 64 contact the second conductive contact blocks 612, forming a series circuit for the first conductive contact block 66, the second conductive contact block 612, the conductive sheet 622, the third conductive contact block 623, and the electromagnet 618 through wires, and powering the electromagnet 618 through an external power supply. The electromagnet 618 is energized to generate a magnetic force, attracting the iron plate 619. During the process of attracting the iron plate 619, the connecting rod 614 at the bottom of the mounting plate 617 is driven to move upward. The connecting rod 614 drives the clamping plate 615 to move upward. The clamping plate 615 locks the ejector rod 63 to fix the ejector rod 63, enabling both the ejector rod 63 and the rubber ejecting block 620 to contact the mold. When clamping a special-shaped mold, they can also contact the special-shaped mold, making the clamping force received by the mold more uniform, and thus improving the stability of clamping the mold.

[0049] After welding is completed, it moves through the principle of the two support plates 44 until the rubber top block 620 disengages from the mold. Driven by the elastic force of the fifth spring 621, the conductive sheet 622 is separated from the third conductive contact block 623, the series circuit is disconnected, the electromagnet 618 loses magnetic force, and driven by the elastic force of the third spring 616, the clamping plate 615 on the connecting rod 614 moves downward, canceling the locking of the ejector rod 63. Driven by the elastic force of the second spring 611, the first conductive contact block 66 is separated from the second conductive contact block 612. Driven by the elastic force of the first spring 69, the second plugging rod 67 is pushed to move. The second plugging rod 67 then drives the ejector rod 63 to move back to its original position through the second spring 611 and the third plugging rod 610, facilitating subsequent repeated use.

[0050] As Figure 1 , Figure 2 , Figure 9 and Figure 10 shown, one side of the mounting plate 2 is provided with a linkage adjustment mechanism 7 for providing power to the first rotation mechanism 3, the clamping mechanism 4, and the second rotation mechanism 5 respectively; the linkage adjustment mechanism 7 includes a second hydraulic cylinder 71 fixed to one side of one of the support ears, the output shaft of the second hydraulic cylinder 71 is fixed with an adjustment plate 72, four second bushings 73 are rotatably arranged through the outer wall of the adjustment plate 72, a second gear 74 is arranged on the outer wall of the second bushing 73, a third gear 75 is arranged on the outer wall of the adjustment plate 72 and between adjacent two second gears 74, the third gear 75 meshes with the second gear 74, double cone teeth 77 are arranged on the outer walls of the first rotating shaft 32, the double-headed lead screw 43, and the first limit shaft rod 51 passing through the inside of the second bushing 73, the lateral distance between adjacent two double cone teeth 77 is greater than the width of the double cone teeth 77, internal meshing teeth 76 matched with the double cone teeth 77 are arranged inside three of the second bushings 73, a rotating motor 78 is fixed to the outer wall of the mounting plate 2, the output shaft of the rotating motor 78 is fixed with a second limit shaft rod 79, one end of the second limit shaft rod 79 passes through the inside of one of the second bushings 73, a second limit groove 710 matched with the second limit shaft rod 79 is arranged inside one of the second bushings 73, a guide rod 712 slidably connected with the adjustment plate 72 is fixed to one side of the mounting plate 2, and a fixing plate 711 rotatably connected with the first rotating shaft 32, the double-headed lead screw 43, the first limit shaft rod 51, and the second limit shaft rod 79 respectively is fixed to the other end of the guide rod 712.

[0051] According to the above structure, start the rotating motor 78. The rotating motor 78 drives the second limit shaft rod 79 to rotate. The second limit shaft rod 79 cooperates with the second limit groove 710 to drive the second gear 74 on the corresponding second shaft sleeve 73 to rotate. The second gear 74 cooperates with the third gear 75 to drive the remaining second gears 74 and second shaft sleeves 73 to rotate. The regulating plate 72 is driven to move by the second hydraulic cylinder 71. The regulating plate 72 drives the internal meshing teeth 76 in the second shaft sleeve 73 to move. When the internal meshing teeth 76 mesh with the corresponding double-cone teeth 77, the first rotating shaft 32, the double-headed screw rod 43 or the first limit shaft rod 51 is driven to rotate. The structure is simple and the operation is convenient, which increases the energy-saving effect of the equipment and can also reduce the number of motors used.

[0052] As Figure 1 and Figure 11 As shown in the figure, a collection mechanism 8 for processing welding debris is provided on the clamping mechanism 4. The collection mechanism 8 includes first umbrella-shaped plates 81 fixed to the opposite sides of two support plates 44 and located below the box body 61. A second umbrella-shaped plate 85 is arranged below the first umbrella-shaped plate 81. One sides of the two second umbrella-shaped plates 85 are hermetically attached to each other. A plurality of second sliding grooves 82 are formed in the outer wall of the first umbrella-shaped plate 81. Second sliders 83 fixed to the second umbrella-shaped plate 85 are slidably installed in the second sliding grooves 82. A fourth spring 84 fixed to the inner side of the second sliding groove 82 is fixed to one side of the second slider 83. A vibration motor 86 is arranged at the bottom of the second umbrella-shaped plate 85. An annular collection groove 9 is arranged at the top of the base 1. A cleaning port 10 is formed in the inner bottom of the annular collection groove 9. A brush plate 11 capable of cleaning the annular collection groove 9 is arranged at the bottom of the mounting plate 2.

[0053] According to the above structure, the debris generated during welding falls onto the first umbrella-shaped plate 81 and the second umbrella-shaped plate 85 and slides into the annular collection groove 9 along the inclined surfaces of the first umbrella-shaped plate 81 and the second umbrella-shaped plate 85. Start the vibration motor 86, which can make the first umbrella-shaped plate 81 and the second umbrella-shaped plate 85 vibrate, avoiding the accumulation of debris on the first umbrella-shaped plate 81 and the second umbrella-shaped plate 85. The debris that falls into the annular collection groove 9 drives the brush plate 11 to rotate in the annular collection groove 9 when the mounting plate 2 rotates, and the debris is cleaned into the cleaning port 10 and collected by an external collection device. The cooperation of the second sliding groove 82, the second slider 83 and the fourth spring 84 enables the second umbrella-shaped plate 85 to move on the second umbrella-shaped plate 85. Then, due to the elastic force of the fourth spring 84, the two second umbrella-shaped plates 85 are always in sealed contact, effectively preventing debris from entering the moving groove 41. It is quite practical.

[0054] As Figure 1 and Figure 11As shown, a first hydraulic cylinder 12 is provided at the top of one of the second umbrella-shaped plates 85. A storage plate 13 is provided at the top of the first hydraulic cylinder 12, and a plurality of rubber protrusions are provided at the top of the storage plate 13.

[0055] According to the above structure, when clamping the mold, the mold can be first placed on the storage plate 13 for preliminary positioning at the top. After the mold is clamped and fixed, the first hydraulic cylinder 12 drives the storage plate 13 to move downward to avoid affecting the up and down rotation of the mold.

[0056] The working principle of the present invention is as follows: Before clamping the mold, the mold can be first placed on the storage plate 13, and the plurality of rubber protrusions at the top of the storage plate 13 are used for preliminary positioning and support of the mold; the rotation motor 78 is started, and the rotation motor 78 drives the second limiting shaft rod 79 to rotate. The second limiting shaft rod 79 drives the second gear 74 on the corresponding second shaft sleeve 73 to rotate through the second limiting groove 710; since the third gear 75 meshes with the second gear 74, the rotation of one second gear 74 drives the rest of the second gears 74 and the second shaft sleeves 73 to rotate synchronously;

[0057] The second hydraulic cylinder 71 is started, and the second hydraulic cylinder 71 pushes the adjusting plate 72 to move along the guide rod 712; during the movement of the adjusting plate 72, the internal meshing teeth 76 of one of the second shaft sleeves 73 are engaged with the double-cone teeth 77 on the double-headed screw rod 43; at this time, the power of the rotation motor 78 is transmitted to the double-headed screw rod 43 through the second shaft sleeve 73, driving the double-headed screw rod 43 to rotate;

[0058] When the double-headed screw rod 43 rotates, since the thread directions at both ends are opposite, the two moving blocks 42 move synchronously towards each other in the moving groove 41; the moving blocks 42 drive the support plates 44 to approach each other, and the support plates 44 further drive the boxes 61 on the mounting shafts 45 to move towards each other; during the movement of the boxes 61 towards each other, the rubber top blocks 620 on the boxes 61 first come into contact with the mold; because the rubber top block 620 has a mounting cavity inside and is provided with a fifth spring 621, when being squeezed, the rubber top block 620 is compressed, and the internal conductive sheet 622 contacts the two third conductive contact blocks 623, forming part of the circuit connection;

[0059] At the same time, the compression of the rubber top block 620 pushes the ejector rod 63 to move into the box 61; the ejector rod 63 drives the first conductive contact block 66 on one side of the first mounting disc 64 to move, so that the first conductive contact block 66 contacts the opposite second conductive contact block 612; as the boxes 61 continue to move until all the rubber top blocks 620 are in contact with the mold, at this time, all the first conductive contact blocks 66 on the first mounting discs 64 are in contact with the second conductive contact blocks 612;

[0060] In this way, the first conductive contact block 66, the second conductive contact block 612, the conductive sheet 622, the third conductive contact block 623, and the electromagnet 618 form a complete series circuit through wires, and the electromagnet 618 is powered by an external power source;

[0061] After the electromagnet 618 is energized, it generates a magnetic force and attracts the iron plate 619; during the process of attracting the iron plate 619, the connecting rod 614 at the bottom of the mounting plate 617 is driven to move upward, and the connecting rod 614 drives the clamping plate 615 to move upward; the clamping plate 615 is arc-shaped at the part below the ejector rod 63. During the upward movement, it locks the ejector rod 63 and fixes the ejector rod 63 to ensure that the ejector rod 63 and the rubber ejector block 620 are in close and uniform contact with the mold, completing the stable clamping of the mold;

[0062] If it is necessary to adjust the left and right positions of the mold, start the second hydraulic cylinder 71 to push the adjusting plate 72 to move; when the adjusting plate 72 moves, the internal meshing teeth 76 of one of the second bushings 73 are engaged with the double-cone teeth 77 on the first rotating shaft 32;

[0063] Keep the rotating motor 78 running. It drives the second limiting shaft rod 79 to rotate. Through a series of transmission components such as the second bushing 73, the second gear 74, and the third gear 75, the first rotating shaft 32 is finally driven to rotate;

[0064] The first rotating shaft 32 drives the first worm 33 to rotate. The first worm 33 is engaged with the first worm gear 35 to drive the first worm gear 35 to rotate; the first worm gear 35 drives the first gear 36 to rotate through the second rotating shaft 34. Since the first gear 36 is engaged with the tooth column 31, the first gear 36 rotates around the tooth column 31, thereby driving the mounting plate 2 to rotate left and right, realizing the precise adjustment of the left and right positions of the mold to meet the requirements of the welding process for the mold position;

[0065] When it is necessary to adjust the mold for up and down rotation, start the second hydraulic cylinder 71 and push the adjusting plate 72 to move again, so that the internal meshing teeth 76 of one of the second bushings 73 are engaged with the double-cone teeth 77 on the first limiting shaft rod 51;

[0066] The rotating motor 78 continues to work, driving the second limiting shaft rod 79 to rotate, and driving the first limiting shaft rod 51 to rotate through the transmission mechanism;

[0067] The first limiting shaft rod 51 drives the second worm 53 to rotate. The second worm 53 is engaged with the second worm gear 55 to drive the second worm gear 55 to rotate; the second worm gear 55 drives the third worm 56 on the third rotating shaft 54 to rotate. The third worm 56 is engaged with the third worm gear 57 to drive the mounting shaft 45 to rotate, thereby realizing the up and down rotation adjustment of the clamped mold and facilitating the welding operation of different angular parts of the mold;

[0068] After the mold clamping is completed, start the first hydraulic cylinder 12 again to drive the placement plate 13 to move downward, so as to prevent the placement plate 13 from hindering the rotation adjustment of the subsequent mold.

[0069] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. The structures, devices and operation methods not specifically described and explained in the present invention, unless otherwise specified and limited, are implemented according to the conventional means in the art.
