Sintering jig for products with grooves

Abstract

The utility model discloses a sintering jig for products with grooves, which comprises a bottom plate and a support plate, the top surface of the bottom plate is provided with a placing groove and a clearance groove which are communicated with each other, and the support plate is arranged in the placing groove. The supporting plate of the sintering jig for the products with the grooves is used for being matched with the grooves of the products to be sintered, and the situation that the yield is affected due to the fact that the grooves of the products contract after being sintered can be prevented. The receding groove is used for receding a protruding part on the side of the groove part of the to-be-sintered product. The supporting plates are clamped into the containing grooves so that the supporting plates and the to-be-sintered products can be prevented from deviating in the transportation process, and therefore the situation that the adjacent to-be-sintered products make contact with one another during sintering, and consequently the products are poor is avoided.

[0030] Furthermore, there are multiple air-avoiding grooves 12 , and the multiple air-avoiding grooves 12 are distributed along the length direction of the support plate 2 .

[0031] It can be seen from the above description that the same support plate 2 can be used to support the grooves of multiple products to be sintered, and the multiple avoidance grooves 12 are respectively used to avoid the protruding parts of multiple products to be sintered.

[0032] Furthermore, the cross section of the air-avoiding groove 12 is rectangular.
