Abstract
The invention discloses a noble metal coin with a transparent anti-counterfeit window, and a manufacturing technology thereof. The coin is composed of a coin substrate and the transparent anti-counterfeit window. The transparent anti-counterfeit window is embedded in the coin substrate. The transparent anti-counterfeit window is formed by a base film and composite surface films on the two faces of the base film. An optical anti-counterfeit mark is printed on the base film, and the surface films are transparent films. The manufacturing technology comprises steps that: a coining mould is manufactured; the transparent anti-counterfeit window is manufactured; a noble metal coin blank is manufactured; the blank is subject to primary coining; an obtained noble metal coin half-finished product is punched; the window sheet is blanked on a set position; and the noble metal coin is subject to secondary coining. According to the invention, the transparent anti-counterfeit window is applied on the noble metal coin, such that a novel approach of noble metal coin anti-counterfeiting is provided. With the technology, anti-counterfeiting performance of the noble metal coin is greatly improved, and a novel technology is combined with a traditional coinage technology. The embedding technology that can not be directly used on metal coins is attached to the metal coin by using the transparent anti-counterfeit window. Therefore, the anti-counterfeiting performance of the product is improved, and a traditional monotonous manifestation that metal is adopted as a coinage material is out-broken.
Description
Technical field
The present invention relates to coinage technical field, the particularly anti-counterfeiting technology of precious metal coin chapter, specifically a kind of precious metal coin chapter and manufacture craft thereof with penetrating false proof form.
Background technology
Along with the fast development of China's economy and improving constantly of living standards of the people, the market demand of gold and silver coin chapter increases day by day, driven by interests, and offender is also becoming increasingly rampant to the imitated of gold and silver coin chapter.The anti-counterfeiting performance that how to improve China's precious metal coin chapter has become very urgent problem.
The false proof process of traditional precious metal coin chapter is mainly manifested in and adopts different sandblast, shot-peenings and regurgitate the local pattern such as sand and process above, also comprises partially plating gold, irregular coin etc. simultaneously.But along with the development of modern industrial technology, improving constantly of process equipment performance, makes the reliability of these traditional coin anti-counterfeiting technologies and security be subject to great challenge, and false proof advantage is no longer obvious.CN101856166A is the immediate prior art of the present invention.
Summary of the invention
A kind of precious metal coin chapter and the manufacture craft thereof with penetrating false proof form providing for the deficiencies in the prior art is provided, and it has improved the anti-counterfeiting performance of precious metal coin chapter greatly, and has visual effect attractive in appearance.Manufacture craft implement after, penetrating false proof form is formed on precious metal coin chapter smoothly, form a kind of have have the precious metal coin of form antifalse effect chapter.Can make masses very clear, improve the anti-counterfeiting performance of product, enrich the artistic expression of precious metal coin chapter.
The object of the present invention is achieved like this:
A precious metal coin chapter with penetrating false proof form, feature is: this coin chapter is made up of matrix and penetrating false proof form, and penetrating false proof form is embedded in matrix.
Described penetrating false proof form forms by basement membrane and at the compound facial mask of positive and negative of basement membrane, wherein, is printed with optical anti-counterfeiting mark on basement membrane, and facial mask is transparent membrane.
Described basement membrane forms for one or more layers Film laminated.
Being shaped as of described penetrating false proof form is circular, quincunx, rectangle, pentalpha or triangle.
The manufacture craft of above-mentioned precious metal coin chapter comprises following concrete steps:
A, making impressing mould
Design is made into after plasterboard and turns over and make resin mold, then adopt horizontal type profiling engraving machine, carve by designing requirement, by repairing a die, machined and heat treatment step make impressing mould;
B, make penetrating false proof form
Penetrating false proof form adopts basement membrane and the structure at basement membrane positive and negative laminated film, first different optical anti-counterfeiting mark is replicated on the basement membrane of tens micron order thickness, at the tow sides transparent membrane of compound hundreds of micron order thickness respectively of this basement membrane, with punch die, its stamping-out is become to difform penetrating false proof form sheet by designing requirement again;
C, making noble metal coin badge blank cake
Adopt existing technology to make noble metal base cake;
D, base cake is impressed for the first time
The mould of making of step a, adopt hydraulic press to impress base cake, form one at the outer shroud at the pre-embedded anti-counterfeiting form sheet of base cake place and be raised in base cake plane and there is certain width and the platform of height, until figure line is all pressed foot, form precious metal coin chapter semi-finished product;
E, to the punching of precious metal coin chapter semi-finished product
Adopt the punch die of the penetrating false proof form sheet of step b stamping-out to carry out punching to the semi-finished product of steps d;
F, to form sheet location blanking
Form sheet is put into the semi-finished product punching position of step e;
G, secondary impression
Adopt marking press to carry out closed impression to the semi-finished product of step f, until form sheet and protruding outer shroud are combined closely.
Manufacture craft of the present invention is to utilize precious metal coin Zhang Yinmo in formation figure line, to form a platform with certain width and height that is raised in precious metal coin chapter plane at the outer shroud of the pre-embedded anti-counterfeiting form of precious metal coin chapter on metal coin stamp; Again to its punching; Utilize secondary impressing mould to pack the form sheet under stamping-out into punching position, and the metal at top is flattened, utilize the mobile of metal to fill form sheet and noble metal gap, and play fixing effect, overall patience reaches existing precious metal coin chapter standard.
The present invention is applied to penetrating false proof form on precious metal coin chapter, open up the new way of precious metal coin chapter anti-counterfeiting technology, not only greatly improve the anti-counterfeiting performance of precious metal coin chapter, and state-of-the-art technology is incorporated in traditional coinage technology, can not be directly used in the technology of putting on metal coin stamp, utilize penetrating form to append to metal coin stamp, the anti-counterfeiting performance of improving product, has broken through coinage material and has adopted the tradition single form of expression of metal.By effective combination of form pattern and product design theme, also can enrich the form of expression of coin chapter, the sensation of finding everything fresh and new to people.
