[0007] Further, the diameter of the positioning column is matched with the hole diameter of the blind hole of the valve core.

[0008] Further, a plurality of support rings are also evenly provided in the grid of the net frame, the upper surface and the lower surface of the support ring are higher than the upper surface and the lower surface of the net frame by a distance, and the upper surface and the lower surface of the support ring are in flush state.

[0009] Further, the outer side of the net frame is also provided with a reinforcing structure.

[0010] Further, the reinforcing structure is a multi-section reinforcing structure, and there is a gap between adjacent two reinforcing structures.

[0011] Further, the reinforcing structure is reinforcing ring, reinforcing frame or reinforcing rib.

[0012] The utility model has the advantages that: a kind of heat treatment frock of blind hole valve core of the utility model has the characteristics of high yield, less manpower and less material consumption;

[0013] Specifically, since the blind hole of the valve core (product) is used as a support auxiliary loading, the outside of the valve core is in a free state and does not contact any object, the outside (outer circle) of the valve core after heat treatment has no black spots, and the color of the surface of the outside (outer circle) of the valve core can be uniform, thereby solving the problem that the surface of the product after heat treatment has black spots and / or black spots.

[0014] In addition, the product only needs to be placed according to the position of the positioning column, which can save a large amount of labor compared with the existing method, improve the efficiency and reduce the labor intensity of the loading person.

[0015] In addition, the tool is made of heat-resistant stainless steel as a base material, and the tool is integrally formed by casting, which increases the strength and the tool is repeatedly used without obvious deformation, thereby solving the problem of large amount of material consumption in loading.
