Description

Technical Field

[0001] The invention relates to the technical field of resin lens production, in particular to a casting and molding device with a defoaming function for producing resin lenses. Background Art

[0002] Resin lenses are optical lenses made of resin materials. They are widely used in optical products such as glasses, photographic equipment, and telescopes because of their lightness, strong impact resistance, good processability, and good UV protection. The production of resin lenses is mostly done by a casting process, where the prepared resin mixture is poured into a mold to ensure that the mold is completely filled, and then demolded after curing.

[0003] However, in the process of introducing the resin mixture into the mold, air is easily filled into the resin mixture in the mold due to the too fast material collection at the end of manual injection, resulting in bubbles, which affects the molding effect of the resin lens and further affects the overall production quality of the resin lens. After the injection is completed, the mold needs to be manually sealed and placed in a curing device for curing, which slows down the overall processing efficiency. For this reason, we propose a casting and molding device with a defoaming function for the production of resin lenses to solve the above problems. Summary of the invention

[0047] After the bubbles are eliminated, the first linear electric rail 11 is controlled to be turned on again to drive the molding mechanism 3 to move horizontally, and the molding mechanism 3 is moved to the curing chamber 6 for curing processing, thereby realizing the synchronous molding processing of multiple resin lenses;

[0048] After molding, the first linear electric rail 11 is controlled to be turned on again to drive the molding mechanism 3 to move horizontally, and the molding mechanism 3 moves out of the curing chamber 6. Subsequently, the driving motors 3561 on both sides are controlled to drive the driving worms 3562 on both sides to drive the driven worm gears 356 to control the rotating horizontal axis 352 to rotate, thereby controlling the driving longitudinal frames 353 on both sides to rotate synchronously, and cooperating with the driving cam 3551 to be movably engaged in the corresponding driven longitudinal groove 3531 and the connection of the driving cross bar 355, driving the top rack 3542 and the bottom rack 3543 to move synchronously in opposite directions, thereby controlling the gear ring frame 354 to rotate, thereby controlling the second side mold 323 to rotate in the molding outer frame 321 through the connection of the connecting rod 324, and demolding the resin lens and the second side mold 323, thereby realizing automatic demolding of the resin lens, and further improving the production efficiency of the resin lens.
