Embodiment Construction

[0040] The following is attached Figure 1-4 The application is described in further detail.

[0041] The embodiment of the present application discloses a mold surface strengthening treatment process and system.

[0042] refer to figure 1 , mold surface strengthening treatment process and system, including the following steps:

[0043] S1, cleaning the surface of the mold with a strong cleaning solvent of Methacron to remove surface impurities;

[0044] S2, using quartz sand to blast the surface of the mold with an air gun, sandblasting the mold in a dry and non-liquid medium, and removing rust, scale, and oil on the surface of the mold to enhance surface adhesion Effect;

[0045] S3, the mold is placed in the molten borax mixture, and the metal carbide coating is formed on the surface of the mold by diffusion at a high temperature of 900-1100 ° C. The metal carbide coating can be carbide of vanadium, chromium, tantalum or titanium, A layer of high-hardness metal carbide...

Abstract

The invention relates to a mold surface strengthening treatment process and system, in particular to the field of molds. The mold surface strengthening treatment process comprises the following steps: cleaning the surface of a mold; performing sand blasting treatment on the surface of the mold by using quartz sand through an air pressure gun; placing the mold in a molten borax mixture, and forming a metal carbide coating on the surface of the mold through diffusion action at the high temperature of 900-1100 DEG C; adjusting the position of a heat radiation heating contact on a hanging bracket according to the model of the corresponding processing mold, placing the mold subjected to coating treatment on the hanging bracket, feeding the hanging bracket into a tempering furnace at a uniform speed, and closing a furnace cover; and carrying out tempering treatment in a vacuum atmosphere, heating the tempering furnace to 500-650 DEG C, carrying out tempering heat preservation for 2-3 hours, cooling to 250-500 DEG C, carrying out tempering heat preservation for 1-2 hours, and carrying out uniform temperature control cooling to room temperature along with the furnace. The process and the system have the effect of uniformly regulating and controlling the surface temperature of the mold.
