Description

Make main body of articles be the casting method that surperficial jewelry, decoration are exposed and had in the part

The present invention relates to a kind of casting method of article, particularly relate to casting Stereo decoration articles, the decoration different on main body of articles with main material, and the casting method that expose the main body of articles part, set off mutually with the primary colors that shows main body of articles itself or speciality and with institute's casting surface jewelry or decoration, thereby improve the economic benefit and the whole sense of worth of main body.

In the past in order to make the article sophistication, decorating on the surface of article (as a tool) has Stereo decoration articles, decoration, with a tool, has the people to bore with artificial edge at pen on one's body, but this pen carve on one's body edge bore pedestal that work spent was artificial many, in the time of can increasing worker or manufacturing cost.Someone makes the three-dimensional decoration of etching on one's body at pen, but etching can only be made the decoration on same plane, can't make more three-dimensional surperficial decoration, and will adopt manually, can increase man-hour and output can't improve.

As shown in Figure 1, be example with another kind of article scent flask, in order to improve the outward appearance of article, cast three-dimensional decoration 10 earlier, normally just, two decorations 100,101 on back of the body two sides, and then two decorations 100,101 are welded on the main body 11 of scent flask, but still have following shortcoming:

(1) can't make one-step casting, can not be one-body molded.

(2) weld has tangible lapping defect, and is not attractive in appearance.

(3) pad is more, is difficult for connecing neat.

(4) speed of production is slow, the cost height.

Another kind method is that the three-dimensional decoration of casting object itself and appearance is one-body molded with mould; but this kind forming method all is to adopt the rigidity mould; and the three-dimensional decoration angle depth and directionality can be subjected to the restriction of rigidity mould; and repair a die or Kai Xinmo very expensive; style also can not change too much because of the costliness of die sinking, and style can't be made too much.

The object of the present invention is to provide a kind of main body of articles to be the part and expose the also casting method of tool surface jewelry, decoration, its characteristics are: on the main body of article, utilize the method for centrifugal casting on main body, to be cast with three-dimensional surface jewelry or the decoration different with main material, and expose with primary colors that shows main body of articles itself or speciality the main body of articles part, and set off mutually with surperficial jewelry of being cast or decoration, improve the economic benefit and the whole sense of worth of main body.

Another object of the present invention is: this main body of articles is the part and exposes the also casting method of tool surface jewelry, decoration, making the groove that is provided with cooperation decoration trend when being shaped on the main body of articles, so that the surface three-dimensional jewelry of diverse location or decoration can process at one time, and make the material of Stereo decoration articles, decoration adhere to more firm.
