Abstract

The invention discloses a spinning and molding device for glassware, which comprises a molding operation system consisting of an upper operating floor and a lower operating floor. A pair of vertically opposite moulds is arranged between the upper operating floor and the lower operating floor; the upper mould is a male mould and the lower mould is a female mould; a pressing jacking device provided with one end connected with the male mould is arranged on the upper operating floor; a positioning mechanism used for positioning the female mould in an operating position and a driving and rotating device used for driving the female mould to rotate are arranged on the lower operating floor; the positioning mechanism comprises a liftable support platform used for supporting the female mould, and a holder arranged on the supporting platform; the holder can be used for positioning the female mould through clamping the female mould in the circumferential direction. As the positioning of the female mould of the molding device is accurate, the molding precision of the obtained glassware is largely improved, and the male mould is preheated in the molding operation system, so that time and labor are saved.

Description

technical field [0001] The invention relates to a glass product molding device, in particular to a large-diameter, high-precision, deep-dome spherical shell glass product molding device. Background technique [0002] With the continuous development of glass application technology, the demand for large-diameter, deep-dome spherical shell hemispherical glass products used in high-level lighting, scientific instruments and photoelectric detection systems is increasing. Generally speaking, the demand for such glass products Forming is usually obtained by pressing, hot bending or rotary methods. Among them, the pressing method is to cast molten glass with a specified weight and a molding viscosity into a mold of a certain shape, and the product is formed according to the shape of the mold under the action of an external force. It has the characteristics of short production cycle and high efficiency, but using this A molding method, due to the high temperature of the molten glass...
