Description
Technical field
The present invention and eyewear art relate in particular to the field of production that is used to make spectacle-frame, earpiece or spectacles arm head.
Background technology
The material of making spectacle-frame, earpiece or spectacles arm head at present mainly contains two big classes:
One class material is a plastic cement, as PC, CP, nylon, rubber, TR90 (transparent nylon) etc., its advantage has been that moulding, the variation of type body structure are more, and cost is lower, but because of the colouring of can only spraying paint of its surface color, can not do high-grade surface treatment or plating, finished product does not have metal-like, does not have class.
One class material is a metal material, as copper-nickel alloy, copper alloy, titanium alloy, almag, magnesium alloy etc.
Wherein the processing of copper-nickel alloy, copper alloy, titanium alloy can not be with die casting or ejection formation, can only use common molding modes such as punching press, roll bending, weld again Deng after the moulding, the glasses finished product that the type material is made is simple, lines are single, do not have third dimension, solder joint easily comes off, fastness is bad, operation is various, the lost labor.
And the intensity of almag is better, density is less, available CNC (Computer numerial control, computer numerical control (CNC) lathe) processing, but its thinner lines and lines can only be made by handwork by the road, back, its processing charges height, yield poorly, the finished product lines are asymmetric, crest line has some setbacks, and moulding is imperfect, and are unsuitable for plating look with common cathodic electricity, usually use anodization, the cost of plating is very high and finished color is single.
The intensity height of magnesium alloy, density are little; material price is low; adding man-hour can be with die casting or ejection formation; can satisfy different Mechanical Builds and fine line; but it is unsuitable for plating look with common cathodic electricity; usually use anodization; the more important thing is that the magnesium molecule is very active; low, the easy blast of its burning-point; so the die casting machinery of magnesium alloy involves great expense, between RMB 1,200,000～1,500,000, the aeration of its job shop requires high greatly; the magnesium molecule that can not contain high concentration in the air, otherwise easily explosion caused.Patent of invention " production method of the die casting magnesium alloy spectacles frame " (patent No.: disclose a kind of production method of making magnesium alloy spectacles frame ZL200710008413.4), as shown in Figure 1 and Figure 2, it adopts the method for die casting to make one and the corresponding integral entity structure of spectacle-frame profile earlier, this structure constitutes by two totally enclosed dull and stereotyped 4,5, again the spectacle-frame semi-finished product being carried out the outside cuts edge, cut out the shape of spectacle-frame, then the half-finished inside of spectacle-frame is cut, car goes out required have square frame 4 ', 5 ' spectacle-frame framework.Though this production method is not used methods such as traditional punching press, extruding, the production danger of having avoided the magnesium molecule to cause, but its production process complexity, the production cost height, especially the glasses finished product higher for fineness or the mirror circle is less is easily slipped up when cutting outside and cutting inside.In addition, though at present existing multiple achievement in research shows the burning-point that can improve magnesium alloy by the method for adding multiple metallic element, rare earth element etc. in magnesium alloy, its cost is too high, is not suitable for the production of spectacles industry.
Summary of the invention
The object of the present invention is to provide that a kind of production process is simple, production cost is lower, and the raw material casting character is good, the production method that can carry out manufacturing spectacle-frame, earpiece or spectacles arm head that the cathode of surface plating handles.

(2), zinc die casting alloys is carried out hot melt, by preliminary working moulding in the die casting machine injection die casting;
(3), treat that the kirsite liquation cools off the back demoulding, carries out machined, polishing, plating again.
Kirsite is the alloy that mainly is added with elements such as aluminium, copper and magnesium, it can be divided into deformation kirsite and cast zinc alloy two classes by processing technology, wherein the flowability of cast zinc alloy and corrosion resistance are all better, now be used for die casting instrument, auto parts shell, household ornaments etc., but in the glasses manufacture field, also be not used for production and processing spectacle-frame, earpiece or spectacles arm head.
Kirsite is compared with glasses raw material such as above-mentioned copper-nickel alloy, copper alloy, titanium alloy, almag, magnesium alloys, has the following advantages:
1, good casting property can satisfy different shaping and meticulousr lines, complicated structure, and cast(ing) surface is smooth;
The surface treatment of 2, can spray, spraying paint, the also cathode treatment that can electroplate;
3, do not inhale iron when fusing and die casting, do not corrode die casting machine inside and die casting, sticking die casting;
4, good normal temperature mechanical performance and wearability are arranged;
5, fusing point is low, at 380 ℃ of i.e. fusings, die casts easily.
The glasses finished color made of kirsite can variation in a word, the production process of more fashion, and die casting is simple, cost is lower, manually less, class is higher.
