Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of fixture technology, and more specifically, to a multi-degree-of-freedom fixture for processing glass molds into preliminary molds. Background Technology

[0002] The initial mold and the preliminary mold are key components in glass forming. They are used to initially shape the high-temperature molten glass droplets into a preliminary shape that is close to the outline of the finished product, laying the foundation for the final shaping in the forming mold. The initial mold and the preliminary mold are mostly made of high-temperature resistant materials such as cast iron and heat-resistant steel. The surface is specially treated to prevent sticking and is also equipped with a cooling system to control the temperature. The cavity of the preliminary mold is relatively simple and focuses on guiding the distribution of the droplets. Although the glass temperature in contact with it is higher and the requirements for high temperature resistance are more stringent, the precision is lower than that of the forming mold. Its design and performance directly affect the quality of the product and the stability of production.

[0003] In the glass mold processing process, the initial mold and the first mold are usually processed by a five-axis milling machine. During the processing, the initial mold and the first mold are clamped and fixed by a fixture. The angle of the initial mold and the first mold is adjusted by rotating the multi-axis support fixture. However, the curvature inside the existing fixture is generally fixed, which makes it difficult to adapt to the clamping and fixing of the initial mold and the first mold of different specifications of glass molds, which can easily affect the processing efficiency of the first mold of different specifications of glass molds. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a multi-degree-of-freedom fixture for processing glass molds into preliminary molds. This fixture addresses the technical problem that the curvature inside the fixture is generally fixed in the prior art, making it difficult to adapt to the molding and clamping of glass molds of different specifications, which in turn easily affects the molding and processing efficiency of glass molds of different specifications.

[0005] According to one aspect, at least one embodiment of this disclosure provides a multi-degree-of-freedom fixture for processing glass molds into preliminary molds, including a rotating shaft, a base plate rotatably connected to the rotating shaft, a plurality of mounting slots being formed at the top of the base plate, and further including: a base plate, support blocks, pressing blocks, and a moving mechanism.

Support blocks are fixedly connected to the top of each of the two base plates, and each of the two support blocks has an arc surface at one opposite end. Two pressing blocks are provided at the top of each of the two support blocks via a clamping mechanism. The clamping mechanism is used to fix the glass mold forming and preliminary mold between the arc surfaces of the two support blocks. The moving mechanism is disposed on the two support blocks and is used to adjust the distance between the two support blocks.

A screw hole is provided on the top plate, and the drive screw is threaded into the screw hole. The limiting nut is threaded onto the drive screw. The support assembly is mounted on the top plate and is used to support the forming and preliminary molds of glass molds of different specifications.

The top of each of the two blocks is fixedly connected to two support springs, and the tops of each pair of adjacent support springs are respectively fixedly connected to the two fixing frames.

[0008] To adjust the spacing between the two support blocks, the moving mechanism includes a bidirectional screw and a guard plate. Each of the two support blocks has a screw hole, and the bidirectional screw is threaded into the two screw holes. Each of the two support blocks has a sliding groove, and the guard plate is slidably connected into the two sliding grooves.

[0009] To install the support block on the top of the substrate, the mounting assembly includes: a connecting block, a stabilizing plate, and a tightening bolt. There are two connecting blocks, each set in a corresponding mounting slot. There are two stabilizing plates, each fixedly connected to both sides of the two connecting blocks. Each stabilizing plate has a screw hole, and the tightening bolt is threaded into the two screw holes.

[0010] To increase the stability of the sliding rods, two sliding holes are provided at the top of the support block, and the two sliding rods are slidably connected in the two sliding holes respectively.

[0011] To increase the stability of the pad when it swings, a rotating groove is provided at the top of the support block, and a rotating block is fixedly connected to the pad, and the rotating block is rotatably connected in the rotating groove.

[0022] like Figures 1-4As shown, this invention discloses a multi-degree-of-freedom fixture for processing glass molds into preliminary molds according to an embodiment of the present invention. The fixture includes a rotating shaft 1, a base plate 2 rotatably connected to the rotating shaft 1, and multiple mounting slots on the top of the base plate 2. It also includes a base plate 3, support blocks 4, a pressing block 6, and a moving mechanism. Two base plates 3 are provided, both mounted on the top of the base plate 2 via mounting components. Support blocks 4 are fixedly connected to the top of each of the two base plates 3. An arc surface 5 is formed on the opposite end of each of the two support blocks 4. The top of each support block 4 is provided with a clamping mechanism. Two pressing blocks 6 and a clamping mechanism are used to fix the glass mold forming and preliminary mold between the arc surfaces 5 of the two support blocks 4. A moving mechanism is set on the two support blocks 4 to adjust the distance between the two support blocks 4. Through the arrangement of the base plate 3, support blocks 4, pressing blocks 6, mounting components, clamping mechanism and moving mechanism, the support position can be adjusted according to the glass mold forming and preliminary mold of different specifications, so as to clamp and fix the glass mold forming and preliminary mold of different specifications, thereby improving the processing efficiency of glass mold forming and preliminary mold of different specifications.

[0023] The clamping mechanism includes: slide rods 7, top plate 8, drive screw 9, limit nut 10, and support assembly. Two slide rods 7 are slidably connected to the top of support block 4. Two sliding holes are formed at the top of support block 4, and the two slide rods 7 are slidably connected within these holes. The top plate 8 is fixedly connected to the top of the two slide rods 7. Two lower pressure blocks 6 are fixedly connected to one side of the top plate 8. The drive screw 9 is rotatably connected to the top of support block 4. A screw hole is formed on the top plate 8, and the drive screw 9 is threaded into the screw hole. The limiting nut 10 is threaded onto the drive screw 9. The support assembly is set on the top plate 8 and is used to support the molding and initial molding of glass molds of different specifications. The support assembly includes: pad 11, pad block 12, fixing frame 13 and support spring 14. Multiple pads 11 are made of rubber. The top of the support block 4 is provided with a rotating groove. A rotating block 20 is fixedly connected to the pad block 12 and rotatably connected in the rotating groove. There are two pads 11, and both pads 11 are fixedly connected to the arc surface 5. The pad block 12 is provided with... There are two pads 12, each rotatably connected to one side of the top plate 8. Two fixing frames 13 are provided, each fixedly connected to the top of the top plate 8. Two support springs 14 are fixedly connected to the top of each of the two pads 12. The tops of each pair of adjacent support springs 14 are respectively fixedly connected to the two fixing frames 13. The operator rotates the drive screw 9, causing the top plate 8 to descend. As the top plate 8 descends, it causes the lower pressure block 6 to press down, thereby forming the glass mold and the initial mold. Pressed on the two pads 11, when the size of the glass mold's final mold and initial mold is small, the top plate 8 descends, causing the pad 12 to descend synchronously, thereby inserting the pad 12 between the glass mold's final mold and initial mold and the support block 4, thus supporting both sides of the glass mold's final mold and initial mold. When the pad 12 contacts the arc surface 5 and continues to descend, the pad 12 will swing around the rotating block 20, thereby driving the pad 12 to be supported and rebounded by the support spring 14 of the fixed frame 13 during the swing process.

[0024] The moving mechanism includes a bidirectional screw 15 and a guard plate 16. Both support blocks 4 have screw holes, and the bidirectional screw 15 is threaded into the two screw holes. Both support blocks 4 have sliding grooves, and the guard plate 16 is slidably connected into the two sliding grooves. When it is necessary to adjust the distance between the two support blocks 4, the operator twists the bidirectional screw 15 to rotate, thereby driving the two support blocks 4 to move relative to each other or move away from each other. In order to prevent the chips during processing from falling onto the bidirectional screw 15, a guard plate 16 is set above the bidirectional screw 15 to prevent the chips from falling onto the bidirectional screw 15.

[0025] The mounting assembly includes: a connecting block 17, a stabilizing plate 18, and a tightening bolt 19. There are two connecting blocks 17, which are respectively set in two corresponding mounting slots. There are two stabilizing plates 18, which are respectively fixedly connected to both sides of the two connecting blocks 17. Each of the two stabilizing plates 18 has a screw hole, and the tightening bolt 19 is threaded into the two screw holes. By inserting the connecting block 17 into the mounting slot and pressing the base plate 2 with the tightening bolt 19, the connecting block 17 is tightened in the connecting slot, thereby stably mounting the base plate 3 on the base plate 2.

[0026] Working principle: When it is necessary to clamp and fix the glass mold forming and initial mold pressing, the glass mold forming and initial mold pressing are placed between two support blocks 4. The operator twists the bidirectional screw 15 to rotate, thereby causing the two support blocks 4 to move relative to each other or move away from each other. The mold forming and initial mold pressing are supported by the pads 11 on the two support blocks 4. The operator twists the drive screw 9 to rotate, which causes the top plate 8 to descend. When the top plate 8 descends, it causes the lower pressing block 6 to press down, thereby pressing the glass mold forming and initial mold pressing. The mold and the initial mold are pressed on two pads 11. When the size of the mold and the initial mold of the glass mold is small, the top plate 8 descends and drives the pad 12 to descend synchronously, thereby inserting the pad 12 between the mold and the initial mold of the glass mold and the support block 4, thus supporting both sides of the mold and the initial mold of the glass mold. When the pad 12 contacts the arc surface 5 and continues to descend, the pad 12 will swing around the rotating block 20. During the swing, the pad 12 is supported and rebounded by the support spring 14 of the fixed frame 13.

[0027] It should also be noted that the support height of the pad 11 is higher than that of the guard plate 16. Therefore, when the glass mold is placed on the pads 11 on both sides, it will not be affected by the guard plate 16.

[0028] It should also be noted that the mold and the primary mold are not installed simultaneously between the two support blocks 4. In actual use, the mold or the primary mold can be installed separately according to the processing flow, or the mold and the primary mold can be installed on two separate machines.

[0029] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
