[0022] To describe in detail the technical content, the achieved purpose and the effects of the present utility model, the following is described in conjunction with the embodiments and with reference to the drawings.

[0023] Please refer to Figures 1 to 3 , a sintering fixture for grooved products, comprising a bottom plate 1 and a support member 2. A card slot 11 is provided on the bottom plate 1. The support member 2 includes a connected support part 21, a product adaptation part 22 and a limit bump 23. The product adaptation parts 22 are respectively arranged at both ends of the support part 21. The limit bump 23 is provided below the support part 21, and the limit bump 23 is snapped into the card slot 11.

[0024] As can be seen from the above description, the beneficial effects of the present utility model are as follows: The two product adaptation parts 22 of the sintering fixture for grooved products are adapted to the groove parts of the products to be sintered, which can prevent the products from undergoing excessive shrinkage during sintering and affecting the yield. The limiting convex blocks 23 are snapped into the card slots 11 to prevent the products to be sintered from shifting in position during transportation, thereby avoiding the contact between adjacent products to be sintered and resulting in defective products.

[0025] Furthermore, a plurality of lifting bosses 12 are also provided on the bottom plate 1, and the top surfaces of the plurality of lifting bosses 12 respectively abut against the bottom surface of the support part 21.

[0026] As can be seen from the above description, the lifting bosses 12 are used to lift the height of the support member 2, avoiding the pressure exerted by the support member 2 on the product and causing defective product dimensions.

[0027] Furthermore, the lifting bosses 12 are respectively provided on both sides of the card slot 11.

[0028] As can be seen from the above description, the lifting bosses 12 are respectively arranged on both sides of the card slot 11 so that the two ends of the support member 2 are balanced in force, avoiding the skewing of the support member 2.

[0029] Furthermore, extension parts 211 are respectively provided on both sides of the support part 21, and the bottom surfaces of the two extension parts 211 respectively abut against the top surfaces of at least one of the lifting bosses 12.

[0030] As can be seen from the above description, the arrangement of the extension parts 211 in contact with the lifting bosses 12 can prevent the lifting bosses 12 from squeezing the space of the product adaptation parts 22, which is beneficial to reducing the length of the product adaptation parts 22, and further reducing the overall length of the sintering fixture for grooved products, facilitating the staff to assemble the sintering fixture for grooved products and the products to be sintered.

[0031] Furthermore, a chamfer structure is provided at the edge of the top surface of the lifting boss 12.

[0032] As can be seen from the above description, the chamfer structure is provided to facilitate the snapping of the limiting convex blocks 23 into the card slots 11.

[0033] Furthermore, the product adaptation part 22 is in the shape of a rectangular body.

[0034] As can be seen from the above description, the sintering fixture for grooved products is used to support the products to be sintered with a rectangular groove structure.

[0035] Furthermore, the support part 21, the product adaptation part 22 and the limiting convex blocks 23 are of an integrally formed one-piece structure.

[0036] As can be seen from the above description, the one-piece forming structure has high structural strength and fewer manufacturing processes.

[0037] Furthermore, a reinforcing rib 24 is provided at the connection between the limiting convex block 23 and the supporting portion 21.

[0038] As can be seen from the above description, the reinforcing rib 24 can increase the structural strength at the connection between the limiting convex block 23 and the supporting portion 21, and reduce the risk of the supporting member 2 being scrapped due to deformation of the limiting convex block 23 during the forming process.

[0039] Furthermore, the supporting member 2 and / or the bottom plate 1 is made of ceramic material.

[0040] As can be seen from the above description, the supporting member 2 and / or the bottom plate 1 is not easily deformed in a high-temperature environment.

[0041] Furthermore, the number of the supporting members 2 is multiple.

[0042] As can be seen from the above description, providing multiple supporting members 2 can improve work efficiency.

[0043] Please refer to Figures 1 to 3 , Embodiment 1 of the present utility model is: a sintering fixture for a grooved product, including a bottom plate 1 and a supporting member 2. A clamping groove 11 is provided on the bottom plate 1. The supporting member 2 includes a connected supporting portion 21, a product adaptation portion 22, and a limiting convex block 23. Product adaptation portions 22 are respectively provided at both ends of the supporting portion 21. A limiting convex block 23 is provided below the supporting portion 21, and the limiting convex block 23 is snapped into the clamping groove 11. Specifically, the product adaptation portion 22 is adapted to the groove portion of the product to be sintered. The clamping groove 11 is a rectangular groove, and the limiting convex block 23 is in the shape of a rectangular body. The number of the supporting members 2 is multiple, and the multiple supporting members 2 are arranged in an array. A plurality of clamping grooves 11 are provided on the bottom plate 1, and the plurality of clamping grooves 11 are arranged in parallel. The multiple supporting members 2 arranged along the extending direction of the clamping groove 11 share one clamping groove 11. In this embodiment, the product adaptation portion 22 is in the shape of a rectangular body. In other embodiments, it is also feasible to set the product adaptation portion 22 as a trapezoidal prism, a cylinder, or other shapes.

[0044] In order to raise the height of the supporting member 2 and avoid the product adaptation portion 22 applying excessive pressure to the product to be sintered, a plurality of lifting bosses 12 are further provided on the bottom plate 1. The top surfaces of the plurality of lifting bosses 12 are flush, and the top surfaces of the plurality of lifting bosses 12 respectively abut against the bottom surface of the supporting portion 21.

[0045] In order to prevent the supporting member 2 from being skewed, lifting bosses 12 are respectively provided on both sides of the clamping groove 11. Specifically, the lifting boss 12 and the bottom plate 1 are an integrally formed one-piece structure.

[0046] In this embodiment, the bottom plate 1 is made of ceramic material.

[0047] On both sides of the supporting part 21, there are respectively provided extending parts 211, and the bottom surfaces of the two extending parts 211 respectively abut against the top surfaces of at least one lifting boss 12. Specifically, both ends of the bottom surface of each extending part 211 are respectively in contact with a lifting boss 12. It is easy to understand that setting the extending part 211 to be in contact with the lifting boss 12 can prevent the lifting boss 12 from squeezing the space of the product adaptation part 22, which is beneficial to reducing the length of the product adaptation part 22, and further reducing the overall length of the sintering fixture for this grooved product, facilitating the staff to assemble the sintering fixture for this grooved product and the product to be sintered.

[0048] In order to facilitate the limiting bump 23 to be inserted into the card slot 11, a chamfer structure is provided at the edge of the top surface of the lifting boss 12.

[0049] A reinforcing rib 24 is provided at the connection between the limiting bump 23 and the supporting part 21. Specifically, the supporting part 21, the product adaptation part 22, the limiting bump 23 and the reinforcing rib 24 are of an integrally formed one-piece structure. It is easy to understand that the reinforcing rib 24 can increase the structural strength at the connection between the limiting bump 23 and the supporting part 21, reduce the risk of the limiting bump 23 deforming during the forming process and causing the support member 2 to be scrapped, and improve the production yield of the support member 2.

[0050] In this embodiment, the support member 2 is made of ceramic material.

[0051] In summary, the two product adaptation parts of the sintering fixture for grooved products provided by the present utility model are adapted to the groove parts of the products to be sintered, which can prevent the products from undergoing excessive shrinkage during the sintering process and affecting the yield. The limiting bumps are inserted into the card slots to prevent the products to be sintered from shifting in position during transportation, thereby avoiding the adjacent products to be sintered from contacting each other and causing product defects. Setting the product adaptation parts at both ends of the supporting part can prevent the support member from skewing and resulting in product size defects.
