Glass utensil mould production method

Abstract

The invention provides the preparing method of glass die, comprising the following steps: 1. making glass die three-dimensional CAD modeling, and making resin master mold used for casting die blank by high-rate forming machine; 2. making resin master mold used for casting spark handling electrode; 3. making core and wood former used for casting die blank; 4. shaping and pouring glass die; 5. making ZrO2 molding pattern and casting spark handling electrode; 6. spark handing glass die, and getting glass die. The invention firstly carries out three-dimensional modeling and makes resin master mold, then uses gypsum model and resin to make core of die blank, and uses blank wood former to shape; the invention uses ZrO2 molding and resin master mold which enlarges the model size to 0.5 - 1.5mm to make spark handling electrode. The method can quickly get die blank and electrode.

Description

Technical field

[0001] The invention provides a method for manufacturing a glass mold, which belongs to the technical field of glass mold processing. Background technique

[0002] Glassware is a living and decorative item widely used in daily life. The traditional production method of glassware is inseparable from glass moulds. In the past, the production process of glass molds generally used the drawings or samples provided by customers to design the mold structure, and then carried out blank production, machining and assembly. When producing glass mold blanks, wooden molds are mostly used for modeling. For wooden molds with complex inner cavity shapes, the production cycle is long and difficult, and the accuracy of wooden mold dimensions is low, resulting in a large machining allowance for mold blanks. In the machining process of molds, CNC machining technology is used for molds with complex curved surface shapes, which need to be completed through CNC programming and CNC...
