Description

Technical Field

[0001] This utility model relates to the field of green body sintering support technology, specifically a vertical sintering support for preventing deformation of the green body. Background Technology

[0002] For core components such as liquid-cooled connectors, block copolymers with specially synthesized structures are used as compatibilizers to significantly improve the compatibility of two polymers that were originally incompatible. This reduces the mixing time of the adhesive system, decreases the amount of adhesive used, and increases the volume content of solid powder in the injection-molded preform. The feedstock prepared with the adhesive reduces the shrinkage rate of the preform during sintering, minimizing sintering deformation and increasing the sintering density of the final sintered body. This allows for efficient and stable fusion of the metal material and modified additives, achieving high-precision and controllable process control. Ultimately, this results in the production of low-cost, highly consistent, reliable, stable, high-density, and highly sealing liquid-cooled connector core components. During sintering, to improve sintering quality, densify the powder, and remove most of the porosity, careful attention should be paid to the placement of the preform during sintering.

[0003] The gear heat treatment placement rack disclosed in the existing patent publication number CN223134511U includes a base plate and a placement assembly. The placement assembly includes multiple placement plates, multiple limiting blocks and cylinders. Each limiting block is fixedly connected to a corresponding placement plate and is located around the bottom of the corresponding placement plate. The base plate and each placement plate have multiple grooves. Each placement plate has a circular hole. Each placement plate is arranged sequentially and sleeved on the cylinder. Each circular hole is adapted to the cylinder. Each limiting block is inserted into a corresponding groove.

[0004] In the aforementioned placement rack, the placement plates need to be removed one by one from the cylinder and then stacked one by one into the heating furnace; after heat treatment, they need to be removed one by one from the furnace and then put back onto the cylinder. During stacking, the limiting blocks and grooves need to be aligned, requiring repeated operations and switching, resulting in poor stability. To address these issues, a vertical sintering support for preventing deformation of the billet is proposed. Utility Model Content

[0032] The protective frame 1 includes a protective frame body 11 and a plurality of placement slots 12 disposed within the protective frame body 11; the plurality of placement slots 12 within the protective frame body 11 can realize the stacking and installation of multiple layers of placement frames 4, thereby increasing the single sintering capacity.

[0033] A closed structure 2 is installed at the opening of the protective frame 11;

[0034] The locking structure 3 is used to fix the closed structure 2 to the opening of the protective frame 11;

[0035] The placement frame 4 is installed inside the protective frame 11. It includes the placement frame 41 and several limiting rods 42 installed on the top of the placement frame 41. Each limiting rod 42 has a limiting groove 43 on both sides and an extension block 44 connected to both ends of the limiting rod 42. One set of extension blocks 44 is provided with a fixing component for fixing the position of the limiting rod 42 on the placement frame 41. The position between two adjacent sets of limiting rods 42 can be adjusted according to actual use needs, or the limiting rods 42 and other components can be replaced.

[0036] The placement mold 5 is provided, with its two sides aligned with the limiting grooves 43. The two sides of the placement mold 5 are aligned with the limiting grooves 43 on the limiting rod 42, and the placement mold 5 is inserted along the limiting grooves 43. The placement mold 5 can be set according to the structure of the blank, so that the blank can be stably placed in the placement mold 5, and the blank is suspended after the placement mold 5 is placed on the placement frame 4.

[0037] Please see Figure 1 and Figure 2 The enclosed structure 2 includes a graphite plate 21 and an L-shaped block 22. The L-shaped block 22 is connected to the side of the graphite plate 21 away from the protective frame 11, and two sets of L-shaped blocks 22 are provided. Specifically, the graphite plate 21 covers the opening of the protective frame 11, and the enclosed structure 2 is fixed by the operating locking structure 3. The graphite plate 21 has the characteristics of high temperature resistance and uniform heat conduction. On the one hand, it can isolate the high-temperature airflow in the sintering furnace from directly impacting the billet, reducing the temperature difference on the surface of the billet; on the other hand, it can make the heat in the furnace evenly transferred to the interior of the protective frame 1, ensuring that multiple layers of billets are heated simultaneously, thus improving the sintering quality.

[0038] Please see Figure 1 and Figure 2The locking structure 3 includes a locking rod 31, a locking hook 32, and a groove 33. The locking hook 32 is installed on the outer wall of the opening of the protective frame 11. The locking hook 32 is provided with a groove 33 that engages with the end of the locking rod 31. The L-shaped block 22 engages with the locking rod 31. The bottom of the protective frame 11 is connected to a support block 34 that contacts the bottom of the graphite plate 21. Specifically, the locking rod 31 is slid down from the top of the L-shaped block 22 against the graphite plate 21. Both ends of the locking rod 31 are engaged in the groove 33 on the locking hook 32. The locking rod 31 is placed in the L-shaped block 22, fixing the position of the graphite plate 21. The support block 34 supports the graphite plate 21.

[0039] Please see Figure 4 and Figure 5 Both sets of extension blocks 44 are provided with sliders 45 on the side near the placement frame 41. The outer side of the placement frame 41 is provided with a moving groove 47 for sliding the sliders 45. One set of sliders 45 is fixedly connected to one side of the extension block 44, and the other set of sliders 45 is movably disposed on one side of the extension block 44. Specifically, by dragging the limiting rod 42, the sliders 45 can slide in the moving groove 47.

[0040] Furthermore, both ends of the movable groove 47 are connected to the outside; specifically, the slider 45 slides out to facilitate the removal of the limiting rod 42.

[0041] Please see Figure 5 The fixing component includes a locking bolt 46 threadedly connected to the extension block 44. The locking bolt 46 extends into the moving groove 47 and rotatably connects to the slider 45. Specifically, by rotating the locking bolt 46 on the extension block 44, since the locking bolt 46 is threadedly connected to the extension block 44 and extends into the moving groove 47 to rotatably connect with the slider 45, loosening the locking bolt 46 can release the tight fit between the slider 45 and the moving groove 47, move the limiting rod 42, and adjust the distance between the two sets of limiting rods 42 according to the size of the placement mold 5. After the adjustment is completed, tighten the locking bolt 46 to press the slider 45 and lock the position of the limiting rod 42 on the placement frame 41.

[0042] Furthermore, both ends of the limiting groove 43 are connected to the outside; specifically, this facilitates the insertion and removal of the mold 5. The limiting groove 43 is connected to the outside to facilitate the quick docking of the mold 5. The limiting groove 43 can restrict the lateral displacement of the mold 5 and ensure the stability of the position after the subsequent blank is placed.

[0043] Furthermore, one end of the placement slot 12 near the opening of the protective frame 11 is connected to the outside, and the placement frame 41 is slidably engaged with the placement slot 12; specifically, to facilitate the placement of the placement frame 41, the placement frame 41 is aligned with the placement slot 12 inside the protective frame 11 and pushed into the placement frame 4 along the placement slot 12.

[0044] The working principle of this utility model is as follows: Based on the size of the blank to be sintered, a suitable placement mold 5 is selected. After loosening the locking bolt 46, the tight fit between the slider 45 and the moving groove 47 is released. The limiting rod 42 is moved, and the distance between the two sets of limiting rods 42 is adjusted according to the size of the placement mold 5. After adjustment, the locking bolt 46 is tightened to press the slider 45, locking the position of the limiting rod 42 on the placement frame 41. The two sides of the placement mold 5 are aligned with the limiting grooves 43 on the limiting rods 42, and the placement mold 5 is inserted along the limiting grooves 43. The limiting grooves 43 restrict the lateral displacement of the placement mold 5, ensuring stable placement of the blank. The blank is placed in the placement mold 5. The placement frame 41 with the placement mold 5 is aligned with the placement groove 12 in the protective frame 11. The placement frame 4 is pushed in along the placement groove 12. Multiple layers of placement frames 4 are stacked in several placement grooves 12 in the protective frame 11. The graphite plate 21 covers the opening of the protective frame 11. The locking rod 31 slides down from the top of the L-shaped block 22 against the graphite plate 21. The two ends of the locking rod 31 are inserted into the grooves 33 on the locking hook 32. The locking rod 31 is placed in the L-shaped block 22 to fix the position of the graphite plate 21. The support block 34 supports the graphite plate 21. The entire bracket enters the sintering furnace in a vertical state.
