AI Technical Summary
The traditional metal powder sintering method results in a lack of support for thin plate products when placed horizontally, causing product deformation during sintering and reducing yield.
A metal powder sintering jig is designed, which includes a jig plate and a positioning and placement area. The positioning and placement area is provided with a placement slot and a support block. The product stands upright in the placement slot, and the bottom of the product is supported by the support slot and the placement slot to ensure that the product is placed vertically to reduce deformation.
Through the support of the support groove and the placement groove, the deformation of the product during the sintering process is reduced and the product yield is improved.

Technical Field
[0001] The utility model belongs to the technical field of sintering jigs, and more particularly relates to a metal powder sintering jig. Background Art
[0002] Metal Injection Molding (MIM) is a new component forming technology that is formed by combining multiple disciplines such as plastic forming technology, polymer chemistry, powder metallurgy technology and metal materials science. It can use mold injection molding blanks and quickly manufacture high-density, high-precision, three-dimensional complex shape structural parts through sintering; it can quickly and accurately materialize design ideas into products with certain structural and functional characteristics, and can directly carry out mass production.
[0003] like Figure 3 For the product shown, the traditional sintering method is to place the product horizontally on a sintering plate. However, since the product is in the shape of a thin plate and none of its sides are horizontal (there are bumps), there will be an unsupported surface on the placement surface when sintering on a flat surface, which will eventually cause deformation of the product during sintering and reduce the product yield. Utility Model Content
[0004] In view of the deficiencies of the prior art, the utility model provides a metal powder sintering jig to reduce deformation of products during sintering and improve product yield.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a metal powder sintering jig, comprising a jig plate, on which a plurality of positioning and placement areas are provided, and a plurality of placement grooves are provided in the positioning and placement areas. The product is upright in the placement groove, and the bottom plane of the product is in full contact with the bottom surface of the placement groove.
[0006] Furthermore, a plurality of first support blocks and second support blocks are provided in the positioning and placement area, a first placement groove is formed between two adjacent first support blocks, a second placement groove is formed between two adjacent second support blocks, and the first placement groove and the second placement groove correspond to each other, the product is located in the first placement groove and the second placement groove, the width of the first placement groove and the second placement groove is the same and greater than the thickness of the product, and one side of the product is in contact with one of the first support blocks and the second support blocks.
[0007] Furthermore, a first supporting groove is provided between the first supporting block and the second supporting block, a second supporting groove is provided on a side of the second supporting block away from the supporting block, and the bottom surface of the second supporting groove is a supporting step.
[0008] Furthermore, the top of the product is higher than the top surfaces of the first support block and the second support block.
[0009] Furthermore, the fixture material is 99 porcelain.
[0010] Compared with the prior art, the beneficial effects of the sintering jig for metal powder are as follows: when sintering products, the products are vertically placed in the first placing groove and the second placing groove, and one side of the products abuts against the side wall of the first placing groove and the second placing groove, the bottom of the products is supported by the bottom of the first supporting groove, the second supporting groove, the first placing groove and the second placing groove, and then the jig is placed in the sintering device for sintering, in this way, the lower end surface of the product is fully supported when sintering, and the product is supported by the first placing groove and the second placing groove, so that the deformation of the product during sintering is effectively reduced, and the yield of the product is improved.
