Description

Technical Field

[0001] This utility model belongs to the field of metallurgical casting technology, specifically relating to a 3.1-4t integral octagonal steel ingot mold for casting. Background Technology

[0002] Currently, small-sized products of special steel still account for a large proportion in the field of die casting technology. The smaller the size, the more production quantity will increase in the same batch. If one mold is used for one ingot type, the number of tooling will increase more than tenfold. This not only involves huge investment amounts but also occupies a lot of space and is difficult to manage. By designing 3.1-4t molds, it is possible to achieve forging and processing of small-sized products of any steel grade from 3.1-4t, reducing investment and improving efficiency.

[0006] The inner cavity of the mold body has a taper of 0 mm 600 mm below the top opening, and the remaining tapers have a = 1.2~2.1%.

[0007] The inner cavity of the mold body has a straight section 600±10mm below the upper opening. The 3.1-4t ingot is cast by the heat-insulating cap floating up and down in the straight section of the inner cavity of the mold body.

[0008] A conical bottom hole is opened at the center of the bottom of the inner cavity of the mold body. The upper diameter is 100±1mm, the lower diameter is 117±1mm, and the height is 135±2mm.
