Compression-casting production method of zinc alloy spectacles frame, spectacles arm or spectacles arm head

Abstract

The invention discloses a method for producing a zinc alloy spectacles frame, zinc alloy spectacles feet or zinc alloy spectacles foot heads through pressure die casting, which comprises the following steps: (1) producing corresponding casting dies according to the spectacles frame, the spectacles feet or the spectacles foot heads, which are required to be subjected to machine shaping; (2) performing hot-melting on pressure die casting zinc alloy, and injecting the molten zinc alloy into the casting dies for primary machine shaping through a pressure die casting machine; and (3) performing demoulding after cooling the molten zinc alloy, and performing machine processing, polishing and electroplating. Compared with the prior spectacles raw material, the zinc alloy has the characteristics of good casting property, capability of performing cathode treatment of electroplating, good normal-temperature mechanical property and abrasion resistance, and low melting point, so that the method is suitable for producing various spectacles; manufactured spectacles finished products have diversified colors and are more fashionable; and the method has the advantages of simple production process of pressure die casting, low cost, small labor and high grade.

Description

Technical field [0001] The invention and the field of spectacles, in particular, relate to the field of production methods for manufacturing spectacle frames, spectacle legs or spectacle legs. Background technique [0002] At present, there are two main types of materials for making spectacle frames, temples, or temples: [0003] One type of material is plastic, such as PC, CP, nylon, rubber, TR90 (transparent nylon), etc. Its advantages are good molding, more changes in the body structure, and lower cost, but because of its surface color, it can only be painted with paint , Can't do high-grade surface treatment or electroplating, and the finished product has no metallic texture and is relatively low-grade. [0004] One type of material is metal materials, such as cupronickel, copper alloy, titanium alloy, aluminum-magnesium alloy, magnesium alloy and so on. [0005] Among them, the processing of cupronickel, copper alloy, and titanium alloy cannot be die-casting or injection mol...

AI Technical Summary

Problems solved by technology

Although this production method does not use traditional stamping, extrusion and other methods to avoid the production hazard caused by magnesium molecules, the production process is complicated and the production cost is high, especially for finished glasses with high fineness or small lens rings. , easy to make mistakes when cutting the outside and cutting the inside

In addition, although a variety of research results have shown that the ignition point of magnesium alloys can be improved by adding various metal elements and rare earth elements to magnesium alloys, the cost is too high and it is not suitable for the production of glasses industry.
