Abstract
The invention relates to a device for rapidly manufacturing a mould through spray forming, and a method for manufacturing the mould. The device comprises a cavity, an induction smelting furnace, a tundish, an atomization spraying mechanism, a whole of a ceramic receiver and a heating device, a three-dimensional oblique rotating device, a lifting device, an axial compression device, an inert gas quenching device, a plurality of operating handles and operating gloves. The method comprises the steps that spray-formed tool and mould steel on the surface of the ceramic receiver is axially compressed in the cavity, holes are completely eliminated, and the surface geometrical morphology and smooth finish of the ceramic receiver are completely replicated; when a cooling pipeline is placed in or the mould does not contain the cooling pipeline, the axially compressed tool and mould steel is subjected to direct gas quenching in the cavity into of a martensite structure, the outer profile is machined outside the cavity, and tempering is conducted; and after axial compression, the tool and mould steel can also be removed from the cavity to be annealed, the cooling pipe and the outer profile aremachined, and quenching and tempering are conducted. The holes in the mould can be reliably and thoroughly eliminated, and the completely accurate mould cavity is obtained.

Double-scanning spray forming preparation method of high-carbon wear resisting tool and mold steel

TL;DR: In this paper, a double-scanning spray forming method for high-carbon wear resisting tool and mold steel was proposed, which has the following advantages: (1) the material structure is more uniform; the performance is higher; and the mass and heat distribution of alloy atomization molten drips of double-nozzle spray is uniform; a deposition blank is more regular in shape; and in two scanning nozzles, one nozzle is used for forming a cylindrical blank, and the other nozzle is mainly used for filling and feeding the middle mass of the blank;
