Abstract
The invention discloses an anti-corrosion die which comprises a forming die core of the die. The surface of the forming die core is coated with an anti-corrosion layer. The anti-corrosion layer is made of Cr-Ni alloy. The mass percent of Cr in the anti-corrosion layer is 60% to 70% and the mass percent of Ni in the anti-corrosion layer is 30% to 40%. The thickness of a high-temperature resistant coating is 0.4mm to 0.6mm. According to the mode, the anti-corrosion performance of the anti-corrosion die is improved, the size and the glossiness of the surface of the die are stable, and the service life of the anti-corrosion die is guaranteed.
Description
Technical field
The present invention relates to a kind of mould that in use there is corrosion-resisting function.
Background technology
In industrial production, can often use various moulds.Under different environments for use to the requirement difference of mould, some injection molds and casting mould in use can be used has corrosive material, these corrosive materials can be corroded mould, and die surface size and smooth finish are changed, and affect the life-span of mould.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of protection against corrosion mould, and this protection against corrosion mould can improve the corrosion resistance of mould, makes die surface size and smooth finish keep stable, is conducive to guarantee the working life of mould.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of protection against corrosion mould is provided, it comprises the formation die core of mould, be coated with corrosion-resistant coating on the surface of described formation die core, described corrosion-resistant coating is the Cr-Ni alloy, the mass percentage content of described Cr in described corrosion-resistant coating is 60%～70%, and the mass percentage content of described Ni in described corrosion-resistant coating is respectively 30%～40%.
In a preferred embodiment of the present invention, the thickness of described high-temperaure coating is 0.4mm～0.6mm.
In a preferred embodiment of the present invention, the mass percentage content of described Cr in described corrosion-resistant coating is 65, and the mass percentage content of described Ni in described corrosion-resistant coating is respectively 35%.
The invention has the beneficial effects as follows: this protection against corrosion mould can improve the corrosion resistance of mould, makes die surface size and smooth finish keep stable, is conducive to guarantee the working life of mould.
Embodiment
Below will the technical scheme in the embodiment of the present invention be clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making all other embodiment that obtain under the creative work prerequisite, belong to the scope of protection of the invention.
Protection against corrosion mould of the present invention comprises the formation die core of mould, be coated with corrosion-resistant coating on the surface of described formation die core, described corrosion-resistant coating is the Cr-Ni alloy, the mass percentage content of described Cr in described corrosion-resistant coating is 60%～70%, and the mass percentage content of described Ni in described corrosion-resistant coating is respectively 30%～40%.The Cr-Ni alloy has good corrosion resistance, can make die surface size and smooth finish keep stable, is conducive to guarantee the working life of mould.
Preferably, the thickness of described high-temperaure coating is 0.5 mm～0.8mm.
Preferably, the mass percentage content of described Cr in described corrosion-resistant coating is 65, and the mass percentage content of described Ni in described corrosion-resistant coating is respectively 35%.Can use method or the electric plating method of spraying the Cr-Ni alloy to be worked into to the surface of formation die core.
Be different from prior art, this protection against corrosion mould of the present invention can improve the corrosion resistance of mould, makes die surface size and smooth finish keep stable, is conducive to guarantee the working life of mould.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
