Description

Technical Field

[0001] This disclosure relates to the field of lens forming equipment technology, and in particular to a novel air-suction forming equipment. Background Technology

[0002] Glass lens forming equipment involves placing a mold containing the workpiece into the cavity of the forming equipment, and then removing it after heating, forming, and cooling. Ordinary forming equipment prevents the workpiece inside the mold from oxidizing by introducing nitrogen into the cavity, which would affect the forming quality. However, the presence of air inside the mold and workpiece can easily lead to poor air venting during the pressing process. To avoid this, current forming equipment requires evacuating the entire forming cavity, which is costly. Utility Model Content

[0014] The main advantages of this disclosure are as follows: This utility model sets a vacuum module in the lower module of the molding mechanism, and connects the lower molding module through the vacuum module to perform a vacuum operation on the mold located on the surface of the lower molding module, thereby removing the air from the mold and the workpiece. Only the vacuum inside the mold needs to be removed, without removing the air from the entire molding cavity, which reduces costs, avoids poor exhaust, and improves the molding effect. Furthermore, when removing the air from the entire molding cavity, it is impossible to guarantee that the air inside the mold is completely removed, resulting in an insufficient molding effect.

[0022] Example like Figure 1-5 As shown, this embodiment provides a novel air-suction molding equipment, including a molding cavity 100. The molding cavity 100 has an inlet 101 and an outlet 102 at its two ends, respectively. The inlet 101 and the outlet 102 are respectively connected to an infeeding mechanism and an outlet mechanism. The infeeding mechanism and the outlet mechanism are cylinder pushing structures in the prior art, used to push the mold containing the workpiece into the molding cavity 100 and finally push it out from the outlet mechanism.

[0023] Specifically, at least one heating mechanism 200, at least one molding mechanism 300, and at least one cooling mechanism are arranged in parallel in the direction from the feed inlet 101 to the discharge outlet 102 within the molding cavity 100.

[0024] The molding mechanism 300 includes an upper molding module and a lower molding module. The upper molding module includes a first lifting module 301 and an upper molding module 302. The first lifting module 301 drives the upper molding module 302 to move closer to or away from the lower molding module. The lower molding module includes a lower molding module 303 and a vacuum module. The vacuum module is connected to the lower molding module 303 and is used to vacuum the mold located in the lower molding module 303. In this embodiment, the vacuum module is used to vacuum the inside of the mold, eliminating the need to remove air from the entire molding cavity 100, resulting in better vacuuming performance and lower cost.

[0025] In this embodiment, the first lifting module 301 is a cylinder used to drive the upper molding module 302 to move up and down, so that it moves closer to or away from the lower molding module. The vacuum module is used to vacuum the mold on the surface of the lower molding module 303, remove the air from the mold and the workpiece, avoid poor exhaust during molding, and improve the quality of workpiece molding.

[0026] Specifically, the molding lower module includes a first heat spreader 3031, a first heating plate 3032, a first heat insulation plate 3033, and a first cooling plate 3034 arranged sequentially from top to bottom. The first heat spreader 3031 has an air intake hole 30311 in the middle and an air intake channel 30312 that is connected to the air intake hole 30311 on the side. One end of the air intake channel 30312 is connected to the vacuum module. The first heating plate 3032 has a first heating element 30321 embedded in it. The first cooling plate 3034 has a first cooling water channel 30341. The first cooling water channel 30341 has a first cooling water inlet 30342 and a first cooling water outlet 30343 at both ends. The first heat spreader 3031 and the first heating plate 3032 are in contact. The first heating plate 3032 has a first heating element 30321 embedded within it. The first heating element 30321 is a common heating element such as a heating wire or heating tube. Heat is transferred through the first heating plate 3032 to the mold located on the surface of the first heat spreader 3031, thereby heating the mold and melting the workpiece for easier pressing and molding. When the mold moves to the surface of the first heat spreader 3031, the through hole at the bottom of the mold aligns with the suction hole 30311. The vacuum module performs vacuuming through the suction channel 30312. Air inside the mold is drawn away through the suction hole 30311 and the suction channel 30312, achieving vacuuming. This equipment requires a mold with a special structure, such as... Figure 6As shown, the mold has a through hole at the bottom, which connects to the cavity inside the mold where the workpiece is placed. When the through hole at the bottom of the mold corresponds to the suction hole 30311, a vacuum operation can be performed inside the mold. The first heat insulation plate 3033 is used to separate the first cooling plate 3034 and the first heating plate 3032, preventing rapid heat loss and saving electricity. Although this will reduce the cooling speed, it is more reasonable from the perspective of energy conservation. The first cooling plate 3034 has a first cooling water channel 30341 inside, which is used to introduce cooling water to cool the mold and regulate the temperature. Cooling water is introduced through the first cooling water inlet 30342. The cooling water exchanges heat during the movement of the first cooling water channel 30341, and the cooled water is discharged from the first cooling water outlet 30343. The cooling operation is continuously carried out by the flowing cooling water.

[0027] Specifically, the vacuum module includes a vacuum pump 503, a vacuum tank 502, a vacuum pipe 501, and a solenoid valve 504. One end of the vacuum pipe 501 is connected to the suction channel 30312, and the other end is connected to the vacuum tank 502. The vacuum tank 502 is connected to the vacuum pump 503 via a pipe. The solenoid valve 504 is located within the vacuum pipe 501. The suction channel 30312 forms a loop through the vacuum pipe 501, the vacuum tank 502, and the vacuum pump 503. The vacuum pump 503 removes air from inside the mold, and the solenoid valve 504 controls the opening and closing of the loop.

[0028] Specifically, the upper molding module 302 includes a second cooling plate 3024, a second heat insulation plate 3023, a second heating plate 3022, and a second heat spreader 3021 connected in sequence. The second heating plate 3022 has a second heating element 30221 embedded in it. The second cooling plate 3024 has a second cooling water channel 30241. The two ends of the second cooling water channel 30241 are respectively provided with a second cooling water inlet 30242 and a second cooling water outlet 30243. In this embodiment, the structure of the upper molding module 302 is basically the same as that of the lower molding module 303, except that the second heat spreader 3021 does not have a suction hole 30311 and a suction channel 30312. The upper molding module 302 and the lower molding module 303 are symmetrically arranged. The structure and working principle of the second cooling plate 3024, the second heat insulation plate 3023, the second heating plate 3022, and the second heat spreader 3021 are the same as those of the lower molding module 303, and will not be described in detail here.

[0029] Similarly, the heating mechanism 200 and the cooling mechanism have the same structure, and the heating mechanism 200 includes an upper heating module and a lower heating module.

[0030] The upper heating module includes a second lifting module 201 and an upper heating module 202. The second lifting module 201 drives the upper heating module 202 to move closer to or away from the lower heating module 203. The upper heating module 202 includes a third cooling plate 2024, a third heat insulation plate 2023, a third heating plate 2022, and a third heat spreader 2021 connected in sequence. The third heating plate 2022 is embedded with a third heating element 20221. The third cooling plate 2024 is provided with a third cooling water channel 20241. The two ends of the third cooling water channel 20241 are respectively provided with a third cooling water inlet 20242 and a third cooling water outlet 20243.

[0031] The heating lower module 203 includes a fourth cooling plate 2034, a fourth heat insulation plate 2033, a fourth heating plate 2032, and a fourth heat spreader 2031 connected in sequence. The fourth heating plate 2032 is embedded with a fourth heating element 20321. The fourth cooling plate 2034 is provided with a fourth cooling water channel 20341. The two ends of the fourth cooling water channel 20341 are respectively provided with a fourth cooling water inlet 20342 and a fourth cooling water outlet 20343.

[0032] In this embodiment, the heating mechanism 200 and the cooling mechanism have the same structure, and the second lifting module 201 is a cylinder used to drive the upper heating module 202 to move closer to or away from the lower heating module 203. Similarly, the upper heating module 202 and the lower heating module 203 have the same structure and are symmetrically arranged. The structure of the upper heating module 202 and the lower heating module 203 is also the same as that of the upper forming module 302, and their functions and principles are the same, so they will not be described in detail here.

[0033] In one embodiment, the heating mechanism 200 can be 1 to 5, and in this embodiment there are three.

[0034] In one embodiment, there are 1 to 3 forming mechanisms 300; in this embodiment, there are two.

[0035] In one embodiment, there are 2 to 6 cooling mechanisms; in this embodiment, there are two.

[0036] The working principle of this utility model is as follows: The mold is pushed into the feed port 101 by the feeding mechanism. The mold enters the first heating mechanism 200 in the forming cavity 100. The upper heating module 202 is driven to move downward by the second lifting module 201, so that the upper heating module 202 and the lower heating module 203 abut against both ends of the mold to heat the mold. After heating one end for a period of time, the mold is transferred to the second heating mechanism 200 by the robot arm set in the forming cavity 100. The robot arm in this embodiment is existing technology. As long as it can transfer the mold from one station to the next station, its specific structure and working principle will not be described in detail here. After the mold enters the second heating station, it continues to be heated. After passing through three heating stations in sequence, it enters the forming mechanism 300. The forming mechanism 300 first removes the air in the mold by the vacuum module, and then drives the upper forming module 302 to move downward by the second lifting module 201 to abut against the top of the mold to press the mold and form the workpiece in the mold. After being pressed by the two forming mechanisms 300, it continues to be moved by the robot arm to the two cooling mechanisms for cooling in sequence. This embodiment sets up three heating mechanisms 200, two forming mechanisms 300, and two cooling mechanisms to gradually heat, form, and cool the mold. Each mechanism operates for the same amount of time. The above only describes the forming process of a single mold. In reality, this equipment can process seven molds simultaneously. The three heating mechanisms 200, two forming mechanisms 300, and two cooling mechanisms work at the same time. When the robot arm moves the molds, it moves all seven molds in the forming cavity 100 at the same time, so that they pass through multiple forming steps in sequence, thereby improving the molding efficiency.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit them. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this disclosure.
