Due to the lack of protection measures during the sliding process of the products, the products may be damaged, and there may be problems with poor refrigeration effect, and the fluidity and stability of the refrigerating liquid cannot be maintained. Therefore, the technical personnel in this field provide a forming device for producing large-diameter optical glass to solve the problems raised in the above background technique. Content of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art, and a forming device for producing large-diameter optical glass is proposed. After the forming platform is driven by the first electric telescopic rod to descend to a suitable position, the second electric telescopic rod pushes the push plate to push the product onto the inclined discharge plate. The design of the inclined discharge plate enables the product to slide smoothly into the collection box. At the same time, the protective pad protects the product from being damaged during the sliding process, realizing the automatic discharge and collection of the product, reducing manual operation, and improving production efficiency. Through components such as the refrigerating liquid storage tank, self-priming pump, and cold transmission pipe, the refrigerating liquid is circulated through the circulating cold transmission and reflux system to maintain the fluidity and stability of the refrigerating liquid, improve the refrigeration effect, ensure the normal operation of the equipment, and improve the efficiency and stability of the refrigeration system. Through the cushion block and the protective shell, the upper die is supported and stabilized by the cushion block, and the protective shell forms a protective outer shell, improving the reliability and service life of the equipment, protecting the equipment from external environments and factors, and at the same time ensuring the production safety of the staff and avoiding accidents.

[0033] When preparing for forming, the first electric telescopic rod 4 contracts, so that the distance between the forming platform 5 and the groove 12 is reduced to the required range, and then the glass melt is poured into the groove 12. After high-temperature processing, it becomes a glass product of the required shape.

[0039] Working principle: When preparing for molding, the first electric telescopic rod 4 contracts, so that the distance between the molding platform 5 and the groove 12 is reduced to the required range. Then the molten glass is poured into the groove 12 and becomes a glass product of the required shape after high-temperature processing. During the molding process, the upper mold 8 rises under the control of the third electric telescopic rod 13 and closely fits with the lower mold 10 to form a molding space. At the same time, the refrigerant storage tank 701 stores the refrigerant, and the self-priming pump 702 pumps out the refrigerant.

The circulation pump 706 pumps the refrigerant out of the circulation tank 705 and injects it back into the refrigerant storage tank 701 through the circulation pipe 707, forming a circulating and reciprocating cold liquid reflux system, maintaining the fluidity and stability of the refrigerant, improving the refrigeration effect, realizing the circulation and reflux of the refrigerant, being beneficial to improving the efficiency and stability of the refrigeration system, ensuring the normal operation of the equipment, and achieving rapid cooling.

[0040] After the forming is completed, the first electric telescopic rod 4 drives the forming platform 5 to descend to a suitable position, and then the second electric telescopic rod 601 extends to push the pushing plate 602 to push the formed product outwards. After the product is pushed onto the inclined discharge plate 603, the inclined angle of the inclined discharge plate 603 causes the product to slide through the discharge port 607 into the collection box 605. During the sliding process of the product, the protective pad 604 is used to protect the product from being damaged during the sliding process. The product is finally collected in the collection box 605, making the discharge and collection of the product automated and efficient, reducing the complexity and labor intensity of manual operation, improving production efficiency and saving production costs.
