Description

Technical Field

[0001] This utility model relates to the field of LED photomask technology, specifically a demolding device for LED photomask casting and curing. Background Technology

[0002] A lampshade, also known as a light cover, is a light-transmitting or light-diffusing component that covers the outside of an LED light source in LED lighting products. It mainly serves to protect and control the light. Some lampshades are combined with metal or thermally conductive plastic to assist in heat dissipation. In the manufacturing process of LED light covers, it is often necessary to use corresponding light cover processing molds to make the light cover.

[0003] The patent CN222473099U discloses a new type of lower template for LED lampshade molds. This patent discloses a technical solution to improve cooling efficiency, which solves the problem that after the existing LED lampshade is heated and formed in the lower mold, the device can only cool the LED lampshade by natural cooling. This not only takes a long time, but also the cooling quality is not ideal, which is not conducive to demolding.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 4 In this embodiment, a demolding device for casting and curing LED photomasks includes a fixing ring 1, a lower mold 4 placed inside the fixing ring 1, an upper mold 6 placed on the top surface of the lower mold 4, and a demolding component for demolding the LED photomask on the fixing ring 1.

[0026] The demolding assembly includes a first electric push rod 20, which is fixedly installed on the bottom surface of the lower mold 4. The output end of the first electric push rod 20 is fixedly connected to a push plate 19. The inner bottom wall of the lower mold 4 has an installation groove 18, and the push plate 19 is placed inside the installation groove 18. The output end of the first electric push rod 20 passes through the lower mold 4 and extends into the installation groove 18. The output end of the first electric push rod 20 and the push plate 19 are fixedly connected. The left and right sides of the lower mold 4 are provided with connection holes 7. A drive rod 3 with one end passing through the connection hole 7 and extending to the outside of the fixing ring 1 is fixedly connected inside each of the two connection holes 7. A drive motor 15 is fixedly installed on the left side of the fixing ring 1. The output shaft of the drive motor 15 is fixedly installed with a driving bevel gear 14. The outer peripheral wall of the drive rod 3 on the left side is fixedly installed with a driven bevel gear 12 that meshes with the driving bevel gear 14.

[0027] Among them, the fixed ring 1 is a rectangular ring, and the two drive rods 3 are rotatably connected to the fixed ring 1 through bearings. The push plate 19 is an arc plate, and the bottom surface of the lower mold 4 is provided with a first through hole. The output end of the first electric push rod 20 passes through the first through hole and is fitted with it with a clearance.

[0028] Specifically, the upper mold 6 and the lower mold 4 are fitted together. Under the action of the upper mold 6 and the lower mold 4, the LED photomask is cast. After the LED photomask has cooled down, the upper mold 6 moves upward and the drive motor 15 is started. The output shaft of the drive motor 15 drives the active bevel gear 14 to rotate. The meshing between the active bevel gear 14 and the driven bevel gear 12 drives the drive rod 3 to rotate, thereby causing the lower mold 4 to rotate. This causes the first electric push rod 20 to be located at the top, and then the first electric push rod 20 is started. The output end of the first electric push rod 20 drives the push plate 19 to move, pushing the LED photomask away from the lower mold 4, and performing demolding of the LED photomask.

[0029] Please see Figures 1 to 4 In this embodiment, the fixed ring 1 is provided with a cooling assembly for cooling the upper mold 6 and the lower mold 4. The cooling assembly includes a water inlet pipe 2. One end of the water inlet pipe 2 is rotatably connected to the right drive rod 3 via a bearing, and the other end passes through the right drive rod 3 and extends into the interior of the lower mold 4. Water storage tanks 8 are provided on opposite sides of the upper mold 6 and the lower mold 4. The water inlet pipe 2 extends into the interior of the bottom water storage tank 8. A water outlet pipe 13 is rotatably connected to the left side of the drive rod 3 on the left side via a bearing. One end of the outlet pipe 13 passes through the left drive rod 3 and extends into the interior of the bottom water storage tank 8. A connecting ring 9 is fixedly connected to the interior of the top water storage tank 8. A connecting groove 16 is provided on the top surface of the connecting ring 9. Rubber rings 17 are fixedly embedded in both the outer and inner peripheral walls of the connecting ring 9.

[0030] Among them, the connecting ring 9 is a rectangular ring, and the two rubber rings 17 are both attached to the bottom water storage tank 8. The lower mold 4 has two support holes, and the water inlet pipe 2 and the water outlet pipe 13 pass through the two support holes and are fitted with them with a gap.

[0031] Specifically, the connecting ring 9 is inserted into the bottom water tank 8. Under the action of the rubber ring 17, the connection between the connecting ring 9 and the bottom water tank 8 is sealed. The coolant enters the bottom water tank 8 under the delivery of the inlet pipe 2. Under the action of the connecting groove 16, the coolant is delivered into the top water tank 8. The coolant cools the LED photomask. Under the delivery of the outlet pipe 13, the coolant is discharged from the water tank 8.

[0032] It should be noted that both the inlet pipe 2 and the outlet pipe 13 are connected to the external coolant storage area.

[0033] Please see Figures 1 to 4 In this embodiment, the fixed ring 1 is provided with a driving component for moving the upper mold 6. The driving component includes two support plates 10, both of which are fixedly connected to the top surface of the upper mold 6. Support grooves 11 are provided on the left and right inner walls of the fixed ring 1. The two support plates 10 extend into the interior of the two support grooves 11 respectively. Two second electric push rods 5 are fixedly installed on the top surface of the fixed ring 1. The output ends of the two second electric push rods 5 pass through the fixed ring 1 and extend to the upper mold 6. The output ends of the two second electric push rods 5 are fixedly connected to the upper mold 6.

[0034] The support plate 10 and the support groove 11 are slidably connected. The top surface of the fixing ring 1 has two second through holes. Two second electric push rods 5 pass through the two second through holes and are fitted with them with a clearance.

[0035] Specifically, the second electric push rod 5 is activated, and the output end of the second electric push rod 5 drives the upper mold 6 to move downward, so that the upper mold 6 and the lower mold 4 fit together. The sliding connection between the support plate 10 and the support groove 11 supports the upper mold 6 and improves the stability of the upper mold 6.

[0036] It should be noted that the first electric actuator 20 and the second electric actuator 5 are both conventional devices known in the prior art, and their specific structures and working principles will not be described in detail here. Furthermore, this application can ensure that the output ends of the two second electric actuators 5 extend and retract simultaneously by using a synchronization controller or other synchronization device, thereby achieving synchronous operation. These synchronization devices are common and mature in the field of electric control, and therefore will not be described in detail in the specific embodiments.

[0037] The working principle of the above embodiments is as follows:

[0038] The second electric push rod 5 is activated, and its output end drives the upper mold 6 to move downward, so that the upper mold 6 and the lower mold 4 fit together. The connecting ring 9 is inserted into the bottom water storage tank 8. Under the action of the rubber ring 17, the connection between the connecting ring 9 and the bottom water storage tank 8 is sealed. Under the action of the upper mold 6 and the lower mold 4, the LED photomask is poured. The coolant is delivered into the bottom water storage tank 8 by the water inlet pipe 2, and the LED photomask is cooled by the coolant. Under the delivery of the water outlet pipe 13, the coolant is discharged from the water storage tank 8. After the LED photomask is cooled, the upper mold 6 is reset, and the drive motor 15 is activated. The meshing between the active bevel gear 14 and the driven bevel gear 12 drives the drive rod 3 to rotate, which in turn causes the lower mold 4 to rotate. Then the first electric push rod 20 is activated, and its output end drives the push plate 19 to move, pushing the LED photomask away from the lower mold 4, and the LED photomask is demolded.

[0039] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
