Description
Technical Field
[0001] The present application relates to the technical field of injection molding die holders, in particular to an automatic flipping fixture for a small injection molding die. Background Art
[0002] A fixture for a small injection molding die is a special tool or device used to fix, position and support the die template in the injection molding process. Its main structure includes a bottom plate, a support bracket installed on the bottom plate, and a mounting plate installed on the support bracket for fixing the injection molding die. The mounting plate is provided with a clamping device for clamping the injection molding die. The clamping device includes two opposite fixing plates, a clamping cylinder arranged on the opposite sides of the two fixing plates and with its output end passing through the fixing plate, and a clamping plate fixedly arranged on the output end of the clamping cylinder. The staff places the injection molding die to be processed on the mounting plate, then starts the clamping cylinder to make the clamping cylinder push the clamping plate to clamp the injection molding die to be processed, and then processes the injection molding die.
[0003] However, in the prior art, some injection molding dies need to be processed on both sides, which leads to the situation that after the staff finishes processing the injection molding die, they need to disassemble the injection molding die, turn it over, and then clamp it again for continuous processing. However, repeated clamping may cause positioning deviation and affect the processing accuracy. Therefore, the present application proposes an automatic flipping fixture for a small injection molding die, which is used to flip the clamped injection molding die, so as to prevent the occurrence of repeated clamping and improve the processing accuracy of the injection molding die. Summary of the Invention
[0004] Aiming at the deficiencies of the prior art, the purpose of the present application is to provide an automatic flipping fixture for a small injection molding die, which is used to flip the clamped injection molding die, so as to prevent the occurrence of repeated clamping and improve the processing accuracy of the injection molding die.
[0005] The above object of the present application is achieved through the following technical solutions: An automatic flipping fixture for a small injection molding die includes a bottom plate, two relatively installed mounting brackets installed on the bottom plate, two relatively installed mounting blocks respectively installed at the tops of the two mounting brackets, a semi-conical groove opened on the opposite sides of the two mounting blocks and penetrating the mounting blocks, a conical rotating column installed in the semi-conical groove, a clamping box fixedly connected to both sides of the two rotating columns, a through hole opened at the upper and lower ends of the clamping box and penetrating the clamping box, a clamping structure installed in the clamping box, and a support assembly installed on the bottom plate directly below the clamping box.
[0006] Further, the clamping structure includes a connecting sliding groove formed on one inner surface of the clamping box along the height direction of the clamping box, a through sliding groove formed on the inner surface of the clamping box opposite to the connecting sliding groove along the height direction of the clamping box and penetrating the clamping box, a positioning plate slidably connected to the inside of the clamping box through the connecting sliding groove, a sliding block slidably connected to the clamping box through the through sliding groove, a connecting screw rod passing through the sliding block and extending into the inside of the clamping box, and a clamping plate provided at one end of the connecting screw rod extending into the inside of the clamping box and rotatably connected to the connecting screw rod. The connecting screw rod is threadedly connected to the sliding block.
[0007] Further, the supporting assembly includes a supporting electric cylinder installed on the bottom plate directly below the clamping box and a supporting plate installed on the output end of the supporting electric cylinder for supporting the injection molding template. The output end of the supporting electric cylinder faces upward.
[0008] By adopting the above technical solutions, when the staff clamps the injection molding template, first start the output end of the supporting electric cylinder to extend, so that the output end of the supporting electric cylinder pushes the supporting plate into the clamping box. Then the staff places the injection molding template on the supporting plate, and then turns the connecting screw rod, so that the connecting screw rod extends into the inside of the clamping box, and the clamping plate cooperates with the positioning plate to clamp the injection molding template. Then the staff continues to start the supporting electric cylinder, so that the output end of the supporting electric cylinder pushes the supporting plate to continue to rise, so that the clamped injection molding template drives the positioning plate and the clamping plate to move upward, so that the injection molding template moves to the upper end of the clamping box. Then the staff can process the injection molding template. When it needs to be turned over, just start the output end of the supporting electric cylinder to contract, so that the supporting plate disengages from the clamping box. Then the staff only needs to turn over the clamping box so that the other side of the injection molding template faces upward. Then start the output end of the supporting electric cylinder to extend again, so that the supporting plate pushes the injection molding template to move to the upper end of the clamping box, and then process the injection molding template. In this way, the staff does not need to repeatedly clamp the injection molding template to turn it over, realizing the flipping of the clamped injection molding template, thereby preventing the occurrence of repeated clamping and achieving the purpose of improving the processing accuracy of the injection molding template.
[0009] Further, extension structures are provided on the end faces at the upper and lower ends of the clamping box to enable the clamping structure to extend out of the clamping box.
[0010] Further, the extension structure includes two groups of first connection blocks and second connection blocks provided on the end faces at the upper and lower ends of the clamping box, which are collinear with the connecting sliding groove and the through sliding groove respectively. An auxiliary sliding groove communicating with the connecting sliding groove is formed on the first connection block, and an extension sliding groove communicating with the through sliding groove is formed on the second connection block.
[0011] By adopting the above technical solution, although the setting of the clamping box allows the staff to turn over the injection molding template without repeatedly clamping the injection molding template, some sides of the injection molding template also need to be processed, and the setting of the clamping box restricts the injection molding template within the clamping box, and the staff cannot process the sides of the injection molding template. The setting of the extension structure solves this technical problem. Through the setting of the extension structure, the clamping structure can extend out of the clamping box through the auxiliary slide groove and the extension slide groove, so that the staff can process the sides of the injection molding template.
[0012] Furthermore, a limiting structure for preventing the clamping box from getting stuck when rotating is provided on one side opposite to the two mounting brackets, and the limiting structure is located below the clamping box.
[0013] Furthermore, the limiting structure includes a receiving circular groove opened on the mounting bracket, a limiting cylinder inserted in the receiving circular groove, and a supporting spring arranged in the receiving circular groove for pushing the limiting cylinder to extend out of the receiving circular groove, and the end of the limiting cylinder away from the supporting spring is a hemispherical portion.
[0014] By adopting the above technical solution and setting the limiting structure, in a normal state, the limiting cylinder is in a state of extending out of the storing circular groove and the top surface abutting against the bottom surface of the clamping box. When the clamping box rotates, the clamping box presses the limiting cylinder to retract into the storing circular groove. When the clamping box rotates 180 degrees, the limiting cylinder is pushed out by the supporting spring, so that the limiting cylinder abuts against the bottom surface of the clamping box again. At this time, if the staff continues to rotate the clamping box, they will feel an obvious sense of jamming. In this way, the staff can accurately rotate the clamping box 180 degrees, preventing the staff from rotating the clamping box too much, and allowing the staff to quickly flip the clamping box.
[0015] Furthermore, a fixing structure for fixing the clamping box is provided on a side of one of the two rotating columns away from the other rotating column.
[0016] Furthermore, the fixing structure includes a control shaft fixedly connected to the rotating column, a plurality of fixing rods arranged on the end of the control shaft away from the rotating column and arranged in a circular array on the axial surface of the control shaft with the center of the control shaft as the base point, a connecting screw hole opened on the fixing rod, a fixing screw hole opened on the mounting bracket opposite to the connecting screw hole, and a fixing bolt which passes through the connecting screw hole and is threadedly connected to the mounting bracket through the fixing rod.
[0017] By adopting the above technical solution and setting up the fixed structure, the staff can rotate the clamping box through the fixed rod, and can fix the clamping box by screwing the connecting screw hole through the fixed rod threaded connection to the mounting bracket, thereby improving the stability of the clamping box and preventing the clamping box from shaking during processing.
[0018] Furthermore, elastic rubber spheres for enhancing the surface friction of the positioning plate and the clamping plate are provided on the mutually opposite surfaces of the positioning plate and the clamping plate, and the elastic rubber spheres are embedded in the surfaces of the positioning plate and the clamping plate.
[0019] By adopting the above technical solution, the stability of the clamping of the positioning plate and the clamping plate is enhanced by the elastic rubber spheres, preventing the injection mold from shifting when the clamping box rotates.
[0020] In summary, the present application includes at least one of the following beneficial technical effects: Through the arrangement of the rotating column, the clamping box, the clamping structure and the supporting assembly, when clamping the injection mold, first start the output end of the supporting electric cylinder to extend, so that the output end of the supporting electric cylinder pushes the supporting plate into the clamping box, then place the injection mold on the supporting plate, and then turn the connecting screw rod so that the connecting screw rod extends into the clamping box, so that the clamping plate cooperates with the positioning plate to clamp the injection mold, and then continue to start the supporting electric cylinder, so that the output end of the supporting electric cylinder pushes the supporting plate to continue to rise, so that the clamped injection mold drives the positioning plate and the clamping plate to move upward, so that the injection mold moves to the upper end of the clamping box, and then the injection mold can be processed. When it is necessary to turn over the injection mold, only need to start the output end of the supporting electric cylinder to contract, so that the supporting plate disengages from the clamping box, and then only need to turn over the clamping box so that the other side of the injection mold faces upward, and then start the output end of the supporting electric cylinder to extend, so that the supporting plate pushes the injection mold to move to the upper end of the clamping box, and then process the injection mold again. In this way, the injection mold can be turned over without repeated clamping of the injection mold, realizing the turning over of the clamped injection mold, thereby preventing the occurrence of repeated clamping and achieving the purpose of improving the processing accuracy of the injection mold.

Detailed implementation manners
[0023] The present application will be further described in detail below with reference to the accompanying drawings.
[0024] Example, refer to Figure 1, An automatic flipping fixture for a small injection molding template, comprising a bottom plate 1, two relatively installed mounting brackets 10 mounted on the bottom plate 1, and then two opposite mounting blocks 11 respectively mounted on the tops of the two mounting brackets 10. Semi-conical grooves penetrating the mounting blocks 11 are formed on the opposite sides of the two mounting blocks 11. A conical rotating column 12 is installed in the semi-conical grooves. A clamping box 13 is located between the two rotating columns 12 and is fixedly connected to the rotating columns 12 on both sides. Through openings penetrating the clamping box 13 are formed at the upper and lower ends of the clamping box 13. A clamping structure 2 is installed in the clamping box 13, and a support assembly 3 is installed on the bottom plate 1 at a position directly below the clamping box 13. The clamping structure 2 includes a connecting chute 20 formed on the inner surface of the clamping box 13 along the height direction of the clamping box 13, a through chute 21 formed on the inner surface of the clamping box 13 opposite to the connecting chute 20 along the height direction of the clamping box 13 and penetrating the clamping box 13, a positioning plate 22 slidably connected to the inside of the clamping box 13 through the connecting chute 20, a sliding block 23 slidably connected to the clamping box 13 through the through chute 21, a connecting screw rod 24 passing through the sliding block 23 and extending into the inside of the clamping box 13, and a clamping plate 25 provided at one end of the connecting screw rod 24 extending into the inside of the clamping box 13 and rotatably connected to the connecting screw rod 24. The connecting screw rod 24 is threadedly connected to the sliding block 23. The support assembly 3 includes a support electric cylinder 30 installed on the bottom plate 1 at a position directly below the clamping box 13 and a support plate 31 installed on the output end of the support electric cylinder 30 for supporting the injection molding template. The output end of the support electric cylinder 30 faces upward. When the staff clamps the injection molding template, first start the extension of the output end of the support electric cylinder 30, so that the output end of the support electric cylinder 30 pushes the support plate 31 into the clamping box 13. Then the staff places the injection molding template on the support plate 31, and then turns the connecting screw rod 24, so that the connecting screw rod 24 extends into the inside of the clamping box 13, so that the clamping plate 25 cooperates with the positioning plate 22 to clamp the injection molding template. Then the staff continues to start the support electric cylinder 30, so that the output end of the support electric cylinder 30 pushes the support plate 31 to continue to rise, so that the clamped injection molding template drives the positioning plate 22 and the clamping plate 25 to move upward, so that the injection molding template moves to the upper end of the clamping box 13. Then the staff can process the injection molding template. When it needs to be turned over, just start the contraction of the output end of the support electric cylinder 30, so that the support plate 31 disengages from the clamping box 13. Then the staff only needs to turn over the clamping box 13 so that the other side of the injection molding template faces upward. Then start the extension of the output end of the support electric cylinder 30 again, so that the support plate 31 pushes the injection molding template to move to the upper end of the clamping box 13, and then process the injection molding template. In this way, the staff does not need to repeatedly clamp the injection molding template to turn it over, realizing the flipping of the clamped injection molding template, thus preventing the occurrence of repeated clamping to improve the processing accuracy of the injection molding template.
[0025] Although the setting of the clamping box 13 allows the staff to turn over the injection molding template without repeatedly clamping the injection molding template, some sides of the injection molding template also need to be processed, and the setting of the clamping box 13 restricts the injection molding template in the clamping box 13, and the staff cannot process the side of the injection molding template. In order to solve this technical problem, refer to Figure 2 In this embodiment, an extension structure 4 is provided on the end surfaces of the upper and lower ends of the clamping box 13 to enable the clamping structure 2 to extend out of the clamping box 13. The extension structure 4 includes two groups of first connecting blocks 40 and second connecting blocks 41 arranged on the end surfaces of the upper and lower ends of the clamping box 13, which are respectively collinear with the connecting slide 20 and the through slide 21. The first connecting block 40 is provided with an auxiliary slide 42 connected to the connecting slide 20, and the second connecting block 41 is provided with an extension slide 43 connected to the through slide 21. Through the provision of the extension structure 4, the clamping structure 2 can extend out of the clamping box 13 through the auxiliary slide 42 and the extension slide 43, so that the staff can process the side of the injection mold.
[0026] Reference Figure 3 as well as Figure 4 In this embodiment, a limiting structure 5 is provided on one side opposite to the other of the two mounting brackets 10 for preventing the clamping box 13 from getting stuck when rotating. The limiting structure 5 is located below the clamping box 13. The limiting structure 5 includes a receiving circular groove 50 provided on the mounting bracket 10, a limiting cylinder 51 inserted into the receiving circular groove 50, and a supporting spring 52 provided in the receiving circular groove 50 for pushing the limiting cylinder 51 out of the receiving circular groove 50. The end of the limiting cylinder 51 away from the supporting spring 52 is a hemispherical portion. Through the setting of the limiting structure 5, in a normal state, the limiting cylinder 51 extends out of the receiving circular groove 50 and the top surface abuts against the supporting spring 52. The state of the bottom surface of the clamping box 13 is that when the clamping box 13 rotates, the clamping box 13 presses the limiting cylinder 51 to retract into the storage groove 50. When the clamping box 13 rotates 180 degrees, the limiting cylinder 51 is pushed out by the supporting spring 52, so that the limiting cylinder 51 abuts against the bottom surface of the clamping box 13 again. At this time, if the staff continues to rotate the clamping box 13, they will feel an obvious sense of jamming, so that the staff can accurately rotate the clamping box 13 180 degrees, preventing the staff from rotating the clamping box 13 too much, so that the staff can quickly flip the clamping box 13.
[0027] In this embodiment, a fixing structure 6 for fixing the clamping box 13 is provided on one side of one of the two rotating columns 12 away from the other rotating column 12. The fixing structure 6 includes a control shaft 60 fixedly connected to the rotating column 12, a plurality of fixing rods 61 arranged at one end of the control shaft 60 away from the rotating column 12 and annularly arrayed on the axial surface of the control shaft 60 with the center of the control shaft 60 as the base point, a connecting screw hole 62 opened on the fixing rod 61, a fixing screw hole opened on the mounting bracket 10 opposite to the connecting screw hole 62, and a fixing bolt 63 that passes through the connecting screw hole 62 and threadedly connects to the mounting bracket 10 through the fixing rod 61. Through the setting of the fixing structure 6, the staff can rotate the clamping box 13 through the fixing rod 61, and can fix the clamping box 13 by screwing the connecting screw hole 62 through the fixing rod 61 and threadedly connecting to the mounting bracket 10, improving the stability of the clamping box 13 and preventing the clamping box 13 from shaking during the processing.
[0028] In this embodiment, elastic rubber spheres 26 for increasing the surface friction of the positioning plate 22 and the clamping plate 25 are provided on the mutually opposite surfaces of the positioning plate 22 and the clamping plate 25. The elastic rubber spheres 26 are embedded in the surfaces of the positioning plate 22 and the clamping plate 25. Through the elastic rubber spheres 26, the clamping stability of the positioning plate 22 and the clamping plate 25 is improved, and the situation of the injection mold shifting when the clamping box 13 rotates is prevented.
[0029] Specific implementation process: When clamping the injection mold, first start the output end of the support electric cylinder 30 to extend, so that the output end of the support electric cylinder 30 pushes the support plate 31 into the clamping box 13. Then place the injection mold on the support plate 31, and then turn the connecting screw 24 so that the connecting screw 24 extends into the clamping box 13, so that the clamping plate 25 cooperates with the positioning plate 22 to clamp the injection mold. Then continue to start the support electric cylinder 30, so that the output end of the support electric cylinder 30 pushes the support plate 31 to continue to rise, so that the clamped injection mold drives the positioning plate 22 and the clamping plate 25 to move upward, so that the injection mold extends out of the clamping box 13 through the auxiliary chute 42 and the extension chute 43, and then the injection mold can be processed. When it needs to be turned over, just start the output end of the support electric cylinder 30 to contract, so that the support plate 31 disengages from the clamping box 13. Then just turn the clamping box 13 so that the other side of the injection mold faces upward. Then start the output end of the support electric cylinder 30 to extend again, so that the support plate 31 pushes the injection mold to extend out of the clamping box 13 through the auxiliary chute 42 and the extension chute 43, and then the injection mold can be processed.
[0030] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of the application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
