Glass mould classification

Glass mould products forming methods according to can be divided into pressure molding, blow molding and mixed forming die 3 kinds. The internal pressure molding products by the punch determine the shape, size determined by the open cavity, mouth inside must be more than other parts of the inner diameter, so as to facilitate the process of forming the punch exit. Blow mould products of the shape of a cavity sure, internal shape in the process of forming natural form, its mouth than other parts of the inner diameter small. Mixed molded products through use or blow molding pressure distribution of die making, get a transition, reoccupy blow molding make products shape. According to the forming process can be divided into early and forming die mould. According to the lubrication methods can be divided into hot mould and synthesizing chloromethane. Apply a synthesizing chloromethane wall lubrication coating, more for blowing thin-wall products, forming and die when rotating relative products. Generally USES the water cooling, the mould synthesizing chloromethane become. Hot model more used to hollow wall products after forming. Mould often USES air cooled, and oil lubrication or add lubrication coating. According to the classification of die structure can be divided into not detachable mode and detachable module and two classes. According to mould supporting method can be divided into hinge or supporting mode and clamp type supporting mode; According to mould structure can be divided into open CAM combining a model combining a model and cylinder. According to shaping can be divided into artificial forming die and mechanical forming dies. Different forming machine, die structure is also different.
