Description

High-strength energy-saving environment-friendly glass forming device Technical Field The invention relates to the technical field of glass forming, in particular to a high-strength energy-saving environment-friendly glass forming device. Background Glass forming is a key process link in glass product production, and is essentially to put high-temperature glass material in a plastic state into a specific cavity, fill the high-temperature glass material with external force and attach the high-temperature glass material to the inner surface of a mold, and then cool and solidify the high-temperature glass material controllably to finally obtain a product with a preset shape and size. Among the molding methods, press molding is widely used because of its high efficiency and suitability for manufacturing solid or thick-walled products with regular shapes, and is particularly important in mass production of building materials such as glass bricks and glass sheets. The process typically applies vertical pressure to the hot frit placed in the mold cavity by the cooperation of the upper and lower molds and the ram, causing it to flow, deform and fill the mold cavity. The pressure plate or the pressure head commonly adopted in the prior art is in a flat plate form with a simple structure. This design makes it difficult to achieve a desired uniformity of pressure distribution on the moldable frit during the extrusion process due to the flat surface of the press plate and the lack of active guiding and regulating mechanisms for the frit flow behavior. When the frit is pressed, the flow rate and direction of each part of the frit are liable to be different, and uneven flow tends to occur from a high pressure part to a low pressure part and from a low resistance part to a high resistance part. Such uneven flow can lead to inconsistent filling of the frit in the mold cavity, which in turn can cause thickness deviations in different areas of the formed glass block. The thickness error not only directly affects the appearance regularity and the dimensional accuracy of the product, but also forms uneven stress distribution in the product, becomes a weak point on the structure, and remarkably reduces the overall mechanical strength, the impact resistance and the long-term durability of the product. Therefore, the core pressing plate structure of the existing pressing device is optimally designed to improve the uniformity of pressure transmission, guide and control the flow of glass frit, and becomes an important technical improvement direction for improving the quality and performance of the glass products such as glass bricks and the like.
