Description

Technical Field

[0001] The utility model relates to the relevant field of glass element processing, in particular to an air suction type mold for glass element processing. Background Art

[0002] With the advancement of science and technology, optical glass lenses are often used in daily life and production processes. Electronic products are developing in the direction of being short, light and multifunctional. For example, digital cameras, computer cameras, mobile phone cameras, video equipment (DV) monitoring equipment, etc. all have requirements for video functions. Therefore, the large-scale production of glass components (especially aspherical lenses) is the key to the popularization of imaging equipment.

[0003] The Chinese patent with patent number CN202322269409.0 discloses "A suction mold for glass element processing". By setting a vent hole in the lower mold to connect the inside of the mold, and then connecting the vent hole through a vacuum pumping device to vacuumize, the air in the mold can be extracted, the oxidation rate of the mold is reduced, and the service life of the mold is increased. When the internal air is extracted to form a negative pressure, the upper mold will be sucked downward to improve the pressing effect;

[0004] This structure has certain advantages, but still has some shortcomings:

[0005] When the mold is evacuated, the air inside the mold is sucked in through the two ends of the horizontal vents and collected in the vertical vents for discharge. Affected by the volume of the horizontal and vertical vents, the T-shaped collecting structure slows down the speed of vacuuming, making it difficult for the air in the mold to be discharged quickly. The concave platform effectively avoids the misalignment of the vertical vents and the exhaust holes of the vacuum machine. This structure may result in an unstable connection if an air pipe is used, resulting in vacuum extraction failure. The vacuum machine can only rely on the exhaust holes to directly connect to the vertical vents, and cannot be connected using air pipes, which has great limitations. Utility Model Content

[0006] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides an air suction mold for glass element processing.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a suction mold for glass element processing, comprising a fixed mold, a connecting device, a molding cavity, glass material, and an upper mold, wherein a molding cavity is arranged inside the fixed mold, and the glass material is placed in the molding cavity, and the upper mold is downwardly embedded in the interior of the fixed mold, and the connecting device is embedded in the bottom end of the fixed mold, and the connecting device comprises a lower mold, an upper ventilation channel, a connecting channel, a lower ventilation channel, a concentration area, a conveying channel, and a connecting piece, the lower mold is embedded in the bottom end of the fixed mold, the top of the lower mold is provided with an upper ventilation channel, and the outer side thereof is provided with a connecting channel, the interior of the lower mold is provided with a lower ventilation channel, and the right end of the lower ventilation channel is connected to the connecting channel, the concentration area is arranged inside the lower mold, and it is connected to the lower ventilation channel, the top of the conveying channel is connected to the concentration area, and it is arranged in the middle of the bottom end of the lower mold, and the connecting piece is locked and fixed with the lower mold by bolts.

[0008] As a further solution of the utility model, the connecting member includes a base, an embedding channel, a spring sheet, and a clamping block. The base is locked and fixed with the lower mold by bolts, an embedding channel is opened inside the base, the embedding channel is connected with the conveying channel, a spring sheet is fixed inside the base, and the clamping block is elastically connected to the base by the spring sheet.

[0009] As a further solution of the utility model, the lower ventilation channels are provided with multiple groups, which are evenly distributed along the circumference, so as to accelerate the extraction of air in the molding cavity.

[0010] As a further solution of the utility model, the connecting point between the lower ventilation channel and the connecting channel is inclined, which is convenient for the rapid extraction of air and improves the extraction speed.

[0011] As a further solution of the utility model, the cross section of the base is "T"-shaped, which is convenient for bolting the connecting piece to the bottom end of the lower mold.

[0012] As a further solution of the utility model, the spring sheets and clamping blocks are provided in two groups, symmetrically distributed at the left and right ends of the base, so as to facilitate the fixed installation of the embedded vacuum pipe and realize the rapid connection between the vacuum pump and the mold.

[0013] As a further solution of the utility model, the diameter of the embedding channel is consistent with the diameter of the conveying channel, which facilitates high embedding of the suction pipe used in the vacuum machine.

This structure effectively avoids the situation that the extraction speed of the gas in the molding cavity slows down when the gas is collected and transported. The gas in the molding cavity is extracted in large quantities and quickly to a concentrated area with a large volume for buffered transportation, thereby realizing the rapid formation of a vacuum environment in the molding cavity. The rapid creation of a vacuum environment in the molding cavity effectively isolates the heat transfer caused by the glass material, thereby avoiding the oxidation of the mold caused by the combination of oxygen and high-temperature hot air, and extending the service life of the mold.

[0017] 2. In the utility model, by setting the connecting piece, the connection between the vacuum machine and the mold is no longer limited to the connection method of directly aligning the vacuum hole of the vacuum machine with the conveying channel. By installing the connecting piece, the suction pipe of the vacuum machine can be directly embedded upward into the embedding channel in the base and stabilized with the help of a clamp block, thereby realizing flexible replacement of the two connection methods and improving the connection flexibility between the vacuum machine and the mold.

DETAILED DESCRIPTION

[0025] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0026] See also Figure 1-2 In the present utility model embodiment:

[0027] A vacuum mold for processing glass elements comprises a fixed mold 1, a molding cavity 3, glass material 4, and an upper mold 5. The molding cavity 3 is arranged inside the fixed mold 1, the glass material 4 is placed in the molding cavity 3, and the upper mold 5 is embedded downward into the fixed mold 1.

[0029] The connecting device 2 is embedded in the bottom end of the fixed mold 1, and the connecting device 2 includes a lower mold 21, an upper ventilation channel 22, a connecting channel 23, a lower ventilation channel 24, a concentration area 25, a conveying channel 26, and a connecting piece 27. The lower mold 21 is embedded in the bottom end of the fixed mold 1, and the upper ventilation channel 22 is arranged at the top of the lower mold 21, and the connecting channel 23 is arranged on the outside thereof. The lower ventilation channel 24 is opened inside the lower mold 21, and the right end of the lower ventilation channel 24 is connected to the connecting channel 23. The concentration area 25 is arranged inside the lower mold 21, and the lower ventilation channel 24 is connected to the connecting channel 23. The lower ventilation channel 24 is connected, the top of the conveying channel 26 is connected to the concentration area 25, and it is arranged in the middle of the bottom end of the lower mold 21. The connecting piece 27 is locked and fixed to the lower mold 21 with bolts. The lower ventilation channel 24 is provided with multiple groups, which are evenly distributed along the circumference to facilitate the extraction of air in the molding cavity 3. The connection between the lower ventilation channel 24 and the connecting channel 23 is inclined, which is convenient for the rapid extraction of air and improves the extraction speed. The gap between the upper ventilation channel 22 and the fixed mold 1 is very small to prevent the glass material 4 from sliding down under the suction.

[0030] When the connector 27 is not used to connect the vacuum machine suction pipe to the lower mold 21 , the vacuum hole of the vacuum machine can be directly connected to the conveying channel 26 to achieve the connection between the vacuum machine and the mold.

[0031] refer to Figure 5-6 , in the embodiment of the utility model:

[0032] The connecting member 27 includes a base 271, an embedding channel 272, a spring sheet 273, and a clamping block 274. The base 271 is locked and fixed with the lower mold 21 by bolts. The base 271 is provided with an embedding channel 272, which is connected to the conveying channel 26. The base 271 is fixed with a spring sheet 273. The clamping block 274 is elastically connected to the base 271 by the spring sheet 273. The cross section of the base 271 is "T"-shaped, which is convenient for bolting the connecting member 27 to the bottom end of the lower mold 21. The spring sheet 273 and the clamping block 274 are both provided with two groups, which are symmetrically distributed at the left and right ends of the base 271, so as to facilitate the embedded exhaust pipe. The vacuum machine and the mold are fixedly installed to realize the quick connection between the vacuum machine and the mold, wherein the outer diameter of the suction pipe used by the vacuum machine is consistent with the conveying channel 26, so as to realize a tight connection, and the clamp block 274 is used to squeeze the suction pipe to realize a stable connection, so as to realize efficient vacuum extraction, and a rubber ring is provided at the connection between the base 271 and the lower mold 21 to increase the tightness between the base 271 and the lower mold 21. At the same time, the bottom end of the base 271 is arranged in an inclined shape to facilitate the suction pipe to be embedded in the embedding channel 272 in the base 271, and the diameter of the embedding channel 272 is consistent with the diameter of the conveying channel 26, so as to facilitate the high embedding of the suction pipe used by the vacuum machine.

[0033] refer to Figure 1-Figure 6 When in use, the vacuum hole of the vacuum machine can be directly aligned with the conveying channel 26 to connect the vacuum machine with the lower mold 21, or the connecting piece 27 can be bolted to the bottom of the lower mold 21, and the suction pipe of the vacuum machine can be upwardly embedded into the embedding channel 272 of the base 271. When embedded, the suction pipe squeezes the clamping block 274 to move inward, so that the clamping block is completely embedded in the interior of the base 271, and continues to move upward to the conveying channel 26, thereby increasing the embedding height of the suction pipe and enhancing the stability of the connection. When the suction pipe stops moving upward, the spring sheet 273 pushes the clamping block 274 to squeeze the suction pipe, clamp the suction pipe, and stabilize the suction pipe, and then;

[0034] The glass material 4 is placed in the molding cavity 3. At the same time, the vacuum machine is started, and the upper ventilation channel 22, the connecting channel 23, and the lower ventilation channel 24 are used to quickly extract the air in the molding cavity 3, and the extracted air is collected in the concentration area 25 for buffer extraction, so as to realize the rapid manufacturing of the vacuum environment inside the molding cavity 3. The heat transfer brought by the glass material 4 is isolated by the vacuum environment in the molding cavity 3, and then the air inside the lower mold 21 is completely extracted through the continuous operation of the vacuum machine to realize the overall vacuum. During the extraction, the negative pressure in the molding cavity 3 drives the upper mold 5 to be pressed down, thereby improving the pressing effect. By using the suction mold, the oxidation rate of the mold is effectively avoided, and its service life is extended.

The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and wiring arrangement in detail.
