Description

Technical Field

[0001] This utility model relates to the field of guide structure technology, and in particular to a guide structure for a metal composite part processing mold. Background Technology

[0002] When metal composite parts are processed, they often need to be processed by stamping, punching, casting and other methods using corresponding molds. In order to ensure stable connection between molds during the processing, a special guide structure is often used to keep the mold movement smooth.

[0003] To address this, patent specification CN211161526U discloses a lifting and guiding structure for a mold, including a liftable upper mold unit positioned above a lower mold unit. The upper mold unit is slidably connected to linear guide rail units arranged on both sides of the mold frame. The upper mold unit is connected to a drive unit mounted on the upper end of the mold frame, allowing it to rise and fall along the linear guide rail units under the drive of the drive unit. This invention, through a liftable upper mold unit positioned above the lower mold unit, slidably connected to linear guide rail units arranged on both sides of the mold frame, and connected to a drive unit mounted on the upper end of the mold frame, allows the mold to move and be guided by linear guide rails for stamping operations. The structure is simple and low-cost. While the above-mentioned guiding structure has a good guiding effect when processing metal composite parts, some problems still exist:

[0004] When the above-mentioned guiding structure is in use, its guiding range is often not adjustable. When the stamping pressure is too high when the mold is closed, it is easy to damage the mold.

[0005] After prolonged use, the aforementioned guide structure is prone to wear due to friction, which can lead to slight deviations in the guiding effect. Utility Model Content

[0006] The purpose of this invention is to provide a guide structure for a metal composite parts processing mold, in order to solve the defect that the guide range of the existing guide structure cannot be adjusted.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a guide structure for a metal composite part processing mold, including a metal processing bottom mold and a guide rod. A metal processing top mold is provided above the metal processing bottom mold. Bases are installed on both sides of the top of the metal processing bottom mold. A guide rod is fixedly connected to the top of the base. A push-pull seat is sleeved on the lower outer side of the guide rod. A correction structure is installed on the top of the push-pull seat. An adjustment structure is provided at one end of the guide rod. The adjustment structure includes a support frame, a bidirectional screw, an internal threaded slide, and a hinge rod. The support frame is located inside the two sets of guide rods. A mounting seat is sleeved on the upper outer side of the guide rod. An auxiliary structure is installed inside the mounting seat.

[0008] When in use, the guide structure is installed on the mold equipment used for processing metal composite parts. When the top mold of the metal processing is driven down by the motor or hydraulic equipment to dock and close with the bottom mold of the metal processing, the ball sleeve will move along the outside of the guide rod, thereby keeping the movement of the top mold of the metal processing stable.

[0009] Preferably, the correction structure includes a bottom half-seat, a traction groove, a docking angle, a top half-seat, a protrusion, and traction beads. The bottom half-seat is installed on both sides of the top of the push-pull seat. A traction groove is provided on one side of the top of the bottom half-seat. A docking angle is provided at the bottom of both ends of the bottom half-seat. Top half-seats are installed on both sides of the bottom of the mounting seat. A protrusion is fixedly connected to one side of the bottom of the top half-seat. Traction beads are provided inside both ends of the protrusion.

[0010] Preferably, the cross-sectional area of ​​the inner diameter of the bottom half seat is greater than the cross-sectional area of ​​the outer diameter of the guide rod, and the traction groove and the protrusion are in the same vertical plane.

[0011] Preferably, the support frame is internally rotatably connected to a bidirectional screw, and both ends of the bidirectional screw are threadedly connected to internal thread slides. Both ends of the internal thread slides are hinged to hinge rods. The two sets of internal thread slides control the pushing and pulling of the push-pull seat through the hinge rods, so that the height of the push-pull seat can be adjusted along the guide rod.

[0012] Preferably, the support frame and the internal threaded slide are in a sliding structure, and the internal threaded slide is in a hinged structure with the base and the push-pull seat respectively through the hinge rod, so that the movement of the bidirectional screw can drive the push-pull seat to push and pull.

[0013] Preferably, the auxiliary structure includes a top cover, a ball sleeve, and a sponge sleeve. The top cover is threaded to the top of the mounting base, and the bottom end of the top cover is fixedly connected to the ball sleeve. The mounting base is provided with a sponge sleeve. Since the surface of the sponge sleeve is coated with a large amount of solid lubricant, the wear of the ball sleeve can be reduced.

[0014] Preferably, the ball sleeve and the guide rod have a sliding structure to avoid excessive friction between the ball sleeve and the guide rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by rotating the bidirectional screw, the push-pull seat can be raised and lowered along the outer side of the guide rod, thereby adjusting the guide sliding range of the mounting seat. When the guide structure causes a slight deviation in the downward pressing of the mold, the traction ball and the traction groove can be docked to correct the slight deviation in the guide movement of the mold. At the same time, a sponge sleeve is placed inside the mounting seat so that when the ball sleeve slides, the surface of the inner ball is coated with the sponge sleeve to absorb lubricating oil, thereby reducing the wear of the structure.

[0016] 1. Control the forward and reverse rotation of the bidirectional screw, so that the two sets of internal thread slides can be pushed and pulled by the hinge rod, so that the height of the push-pull seat can be adjusted along the guide rod, thereby adjusting the guide range of the metal processing top mold driven by the mounting seat;

[0017] 2. A sponge sleeve containing a large amount of solid lubricant is placed inside the mounting base. As the metal processing die moves, the balls inside the ball sleeve gradually roll due to friction with the outer wall of the guide rod. During the rolling process, the surface of the balls will be covered with lubricant, thereby reducing the wear between the ball sleeve and the guide rod. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model provides a guide structure for a metal composite part processing mold, including a metal processing bottom mold 1 and a guide rod 4. A metal processing top mold 2 is arranged above the metal processing bottom mold 1. Bases 3 are installed on both sides of the top of the metal processing bottom mold 1. The top of the base 3 is fixedly connected to the guide rod 4. A push-pull seat 5 is sleeved on the lower outer side of the guide rod 4. An mounting seat 8 is sleeved on the upper outer side of the guide rod 4. A correction structure 6 is installed on the top of the push-pull seat 5. The correction structure 6 includes a bottom half seat 601, a traction groove 602, a docking angle 603, a top half seat 604, and a convex... Block 605 and traction bead 606, bottom half seat 601 is installed on both sides of the top of push-pull seat 5, traction groove 602 is opened on one side of the top of bottom half seat 601, and docking corner 603 is provided at the bottom of both ends of bottom half seat 601. Top half seat 604 is installed on both sides of the bottom end of mounting seat 8, and protrusion 605 is fixedly connected to one side of the bottom end of top half seat 604. Traction bead 606 is provided inside both ends of protrusion 605. The cross-sectional area of ​​the inner diameter of bottom half seat 601 is larger than the cross-sectional area of ​​the outer diameter of guide rod 4. Traction groove 602 and protrusion 605 are in the same vertical plane.

[0026] See attached document Figure 1 , Figure 2 and Figure 3 When the metal processing bottom mold 1 and the metal processing top mold 2 are closed, the metal composite can be precisely processed due to the precise alignment of the molds. However, when the guide structure is worn or caused by external force, the metal processing top mold 2 cannot be stably guided downwards, and the metal processing bottom mold 1 and the metal processing top mold 2 cannot be precisely aligned, resulting in the metal composite being produced unqualified. To address this, a bottom half seat 601 and a top half seat 604 are installed at the top of the push-pull seat 5 and the bottom of the mounting seat 8, respectively. When the metal processing bottom mold 1 and the metal processing top mold 2 are closed, the bottom protrusion 605 of the top half seat 604 will gradually insert into the traction groove 602. If the guide is slightly misaligned, the protrusion 605 will forcibly correct the slightly misaligned metal processing top mold 2 along the traction groove 602, thereby preventing the metal composite from being produced unqualified.

[0027] One end of the guide rod 4 is provided with an adjustment structure 7. The adjustment structure 7 includes a support frame 701, a bidirectional screw 702, an internal thread slide 703, and a hinge rod 704. The support frame 701 is located inside the two sets of guide rods 4. The bidirectional screw 702 is rotatably connected inside the support frame 701. Both ends of the outer side of the bidirectional screw 702 are threadedly connected to the internal thread slide 703. Both ends of the internal thread slide 703 are hinged to the hinge rod 704. The support frame 701 and the internal thread slide 703 are in a sliding structure. The internal thread slide 703 is hinged to the base 3 and the push-pull seat 5 respectively through the hinge rod 704.

[0028] See attached document Figure 1 , Figure 2 and Figure 4 When the guide structure guides the metal composite, in order to avoid excessive pressure on the metal processing top mold 2, which would cause excessive force and damage to the metal processing bottom mold 1 and the metal processing top mold 2, a support frame 701 is set on the inner side of the two sets of guide rods 4 on the same side. Rotating the bidirectional screw 702 causes the two sets of internal thread slides 703 on its outer side to move in opposite directions. By controlling the forward and reverse rotation of the bidirectional screw 702, the movement direction of the two sets of internal thread slides 703 is controlled. Then, the push-pull seat 5 is controlled by the hinge rod 704, so that the height of the push-pull seat 5 is adjusted along the guide rod 4. In turn, the mounting seat 8 drives the metal processing top mold 2 to adjust the guiding range. When the metal processing top mold 2 is excessively pressed down, the blocking of the push-pull seat 5 prevents the mounting seat 8 from driving the metal processing top mold 2 to be excessively pressed down.

[0029] An auxiliary structure 9 is installed inside the mounting base 8. The auxiliary structure 9 includes a top cover 901, a ball sleeve 902, and a sponge sleeve 903. The top cover 901 is threaded to the top of the mounting base 8, and the ball sleeve 902 is fixedly connected to the bottom end of the top cover 901. The sponge sleeve 903 is provided inside the mounting base 8, and the ball sleeve 902 has a sliding structure with the guide rod 4.

[0030] See attached document Figure 5 When this guide structure is in use, the metal processing die 2 is driven to move up and down by a motor or hydraulic equipment. During the movement, the mounting base 8 slides along the outside of the guide rod 4. The frequent movement of the metal processing die 2 causes wear between the guide rod 4 and the ball sleeve 902 due to friction. When the wear is excessive, the up and down movement of the metal processing die 2 may be slightly deviated. To reduce wear, a sponge sleeve 903 with a large amount of solid lubricant is placed inside the mounting base 8, and the ball sleeve 902 is fitted inside the sponge sleeve 903. After the top cover 901 is threadedly connected to the mounting base 8 and installed inside the metal processing die 2, the balls inside the ball sleeve 902 gradually roll due to friction with the outer wall of the guide rod 4 as the metal processing die 2 moves. During the rolling process, the surface of the balls will be contaminated with lubricant, thereby reducing the wear between the ball sleeve 902 and the guide rod 4.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
