Production process for molding fully-stereoscopic seamless hollowed-out accessory

Abstract

The invention discloses a production process for molding a fully-stereoscopic seamless hollowed-out accessory at one time, and aims to solve the problems of direct influence on a molding effect of an accessory product caused by unavoidable formation of original traces such as a splicing line, a welding point and a positioning seam allowance on the product through a splicing method in an existing hollowed-out accessory manufacturing process, deformability of the product and difficulty in guaranteeing of accessory quality. A required style is designed through three-dimensional molding, a reinforced plastic (RP) original type is obtained through a quick photo-curing molding machine, and a silicon rubber mold is manufactured according to the RP original type; a corresponding degradable liner is manufactured according to a part of the product, needing to be hollowed out; a casting cavity is formed between the silicon rubber mold and the degradable liner; after centrifugal casting, a cast product is put into water, and the degradable liner is dissolved into the water to obtain a finished product. The production process is high in production efficiency and low in production cost; the product can be cast at one time without welding; the internal quality and external quality of the product are stable; the yield is high.

Description

technical field [0001] The invention relates to the technical field of metal jewelry production, in particular to a production process for one-time forming full three-dimensional seamless hollowed-out jewelry accessories. Background technique [0002] The traditional production process of hollow jewelry accessories adopts the splicing method. After splicing, it needs to be welded and fixed. The product inevitably has original traces such as splicing lines, solder joints, and positioning stops, which directly affects the modeling effect of the jewelry product, and the product is easy to change. The quality of accessories Difficult to guarantee. [0003] The jewelry rapid prototyping process generally consists of three parts: pre-processing, prototype manufacturing and post-processing. Pre-processing refers to the three-dimensional modeling of jewelry, generating a CAD model, and then performing auxiliary graphics processing on the CAD model such as hollowing out, adding supp...
