Description

Technical Field

[0001] This utility model relates to the field of optical lens equipment technology, and specifically discloses a mold for manufacturing optical lenses. Background Technology

[0002] Optical glass is made by mixing high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc., according to a specific formula, melting them at high temperature in a platinum crucible, and then stirring them ultrasonically to remove air bubbles. It is then slowly cooled over a long period to prevent internal stress in the glass block. After cooling, the glass block must be measured with optical instruments to check whether its purity, transparency, uniformity, refractive index, and dispersion meet specifications. Qualified glass blocks are then heated and pressed to form optical lens blanks. Molds are required in the manufacturing process of optical lenses.

[0003] The existing molds used for manufacturing optical lenses have the following defects:

[0004] One model of optical lens corresponds to one mold. Multiple varieties require a large amount of material to process and manufacture concave molds, which is very costly.

[0005] Furthermore, the existing optical lens manufacturing molds require the molds to be left to cool naturally after molding, which is a slow molding process, increasing working time and reducing work efficiency. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0024] Please see Figure 1-4 A mold for manufacturing optical lenses includes a base 1 and a mold support 2 located on top of the base 1. The mold support 2 has a gantry structure. The top of the mold support 2 has an installation groove 3, and a mold base 4 is provided in the installation groove 3. A guide block 5 is provided on one side of the upper outer wall of the mold base 4, and a guide groove 6 adapted to the guide block 5 is provided on one side of the installation groove 3. A hidden groove 7 and a locking groove 8 are respectively provided on the inner wall of the installation groove 3 and the outer wall of the mold base 4. A locking block 9 is provided in the hidden groove 7, and one end of the locking block 9 is inserted into the locking groove 8. A telescopic device 10 is provided on the mold support 2, and the output end of the telescopic device 10 is provided on the locking block 9. Handle grooves 11 are provided on both sides of the top of the mold base 4. The telescopic device 10 is an electric telescopic rod, a pneumatic telescopic rod, or a hydraulic telescopic rod.

[0025] In this embodiment: all the die holders 4 have the same external structure and are adapted to the mounting groove 3 on the top of the die holder 2. Mold core cavities for processing optical lenses of different models and specifications are respectively opened on the top of multiple die holders 4. The die holder 4 is placed in the mounting groove 3 by aligning the guide block 5 on the die holder 4 with the guide groove 6. The guide block 5 is locked in the guide groove 6, facilitating quick and easy alignment and leveling of the die holder 4, ensuring that the top ends are in the same plane, thus guaranteeing the overall stability and balance of the equipment. Furthermore, when the telescopic device 10 is activated, one end of the locking block 9 moves out of the hidden groove 7. The locking block 9 is locked in the locking groove 8, which restricts and fixes the die holder 4, so that the die bracket 2 and the die holder 4 form a complete die assembly. When replacing, the locking block 9 resets, and the die holder 4 in the die bracket 2 can be easily taken out through the handle groove 11. The die holder 4 to be replaced can be assembled into the mounting groove 3 on the top of the die bracket 2. The die bracket 2 is shared, and only the die holder 4 needs to be replaced. This mold greatly reduces the die processing cost, maintenance and management cost, and labor intensity of operators when changing molds, while improving the changeover speed.

[0026] As a technical optimization of this utility model, a groove 12 is opened at the bottom of the die holder 4, and a cooling coil 13 is provided in the groove 12 and is attached to the die holder 4; a chiller 14 is provided below the die bracket 2 and is fixedly connected to the top of the base 1, and the water inlet pipe and water outlet pipe of the chiller 14 are connected to the cooling coil 13 through pipes respectively.

[0027] In this embodiment: the cooling coil 13 is in contact with the die holder 4. When the chiller 14 is started, cooling water can be circulated to the cooling coil 13, which makes it easy to cool down the die holder 4.

[0028] As a technical optimization of this utility model, the top of the inner cavity mold bracket 2 is provided with a through groove 15 that communicates with the mounting groove 3, and a fan 16 is provided in the through groove 15.

[0029] In this embodiment: Activating the fan 16 in the through slot 15 makes it easy to deliver cold air into the mounting slot 3, and the cold air makes it easy to cool down the die holder 4 again.

[0030] As a technical optimization of this utility model, a rectangular groove 17 is opened on the inner wall edge of the groove 12, and a first through hole 18 is opened inside the rectangular groove 17. A second through hole 19 communicating with the first through hole 18 is opened on the die bracket 2.

[0031] In this embodiment: the first through hole 18 and the second through hole 19 further facilitate the airflow out of the mounting groove 3, and the airflow in the mounting groove 3 facilitates the rapid cooling of the die holder 4.

[0032] As a technical optimization of this utility model, a filter cover 20 that is detachable from the through groove 15 is provided below the fan 16.

[0033] In this embodiment, the filter cover 20 filters the air entering the channel 15, preventing dust and impurities in the fresh air from accumulating on the fan blades of the fan 16.

[0034] Working principle and usage process of this utility model:

[0035] The guide block 5 on the die holder 4 is aligned with the guide groove 6. The die holder 4 is placed in the mounting groove 3, and the guide block 5 is locked in the guide groove 6. The telescopic device 10 is activated, and one end of the locking block 9 moves out from the hidden groove 7 and is locked in the locking groove 8, which restricts and fixes the die holder 4, so that the die holder 2 and the die holder 4 form a complete combined die part. When replacing, the locking block 9 is reset, and the die holder 4 in the die holder 2 can be easily taken out through the handle groove 11. During processing, the chiller 14 and the fan 16 are started. The chiller 14 circulates cooling water to the cooling coil 13, which can easily cool the die holder 4. The cold air enters the groove 12 and flows through the first through hole 18 and the second through hole 19, which can make the internal airflow flow quickly, which can easily carry away some of the heat on the die holder 4 and make the die holder 4 cool down quickly.
