Description

Technical Field

[0001] This utility model relates to the field of rearview mirror processing technology, and in particular to a cooling device for hot-bent rearview mirrors. Background Technology

[0002] Rearview mirrors are a very important component of automobiles and other vehicles. They are mainly used to help drivers observe the situation behind or to the side of the vehicle to ensure driving safety. During processing, they need to be hot-bent. After hot bending, they need to be placed in a cooling equipment along with the outer mold for cooling. Therefore, a cooling equipment is required.

[0003] Patent CN112079554A discloses a cooling device for hot bending glass processing equipment, including a support frame, an upper cooling plate, and a lower cooling base plate. A water inlet connector for the lower cooling base plate is installed in the middle of the upper end of the upper cooling plate, and water outlet connectors for the lower cooling base plate are installed on both sides of the upper end of the upper cooling plate. A lower cooling pipe is installed between the water inlet connector and the water outlet connector, and the density of the lower cooling pipe decreases from the middle to both sides. A second connecting hose and a third connecting hose are installed in the middle of the interior of the lower cooling base plate.

[0004] In the above case, the equipment pushes the mold between the upper cooling platen and the lower cooling base plate and clamps it. Cooling is achieved through the serpentine cooling pipes inside the upper cooling platen and the lower cooling base plate. However, after cooling is completed, each mold needs to be manually unloaded, which increases the labor burden. Cooling is achieved by the coolant flowing inside the cooling pipes. The coolant is separated from the mold by the pipes and the platen, resulting in a slow cooling speed and reduced cooling efficiency. At the same time, the coolant flows in the pipes, causing different contact times with different areas of the mold's exterior, resulting in uneven cooling and easily affecting the cooling effect. Utility Model Content

[0005] The purpose of this invention is to provide a cooling device for hot-bent rearview mirrors to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hot-bent rearview mirror cooling device, comprising a processing table, a cooling box fixedly connected to the top of the processing table, and side frames fixedly connected to the front and rear ends of the top of the processing table. The cooling box passes through the inner side of the side frame, and a clamping assembly is slidably connected to the inner side of the side frame. A lead screw is rotatably connected to the inner side of the side frame, and the clamping assembly is threadedly connected to the outer side of the lead screw. The cooling box includes a first cavity, a second cavity, and a third cavity opened sequentially from left to right on the inner side. A pre-cooling assembly is fixedly connected to the inner side of the first cavity, and a cooling assembly is fixedly connected to the inner side of the second cavity.

[0007] In a preferred embodiment, a transport mechanism is fixedly connected to both sides of the top of the processing table, a support is fixedly connected to the top of the processing table inside the two clamping components, and a forward and reverse motor is fixedly connected to the outer side of the side frame, with its output end fixedly connected to the lead screw on the same side.

[0008] In a preferred embodiment, the clamping assembly includes a sliding seat slidably connected to the inner side of the side frame, the sliding seat being threadedly connected to the outer side of the lead screw, and an inner groove for the movement of the two sliding seats being provided inside the cooling box.

[0009] In a preferred embodiment, the upper and lower ends of the two adjacent sides of the moving seats are provided with sliding grooves, and clamping plates are slidably connected to the inner side of the sliding grooves. A bidirectional electric cylinder is fixedly connected to the inner side of the moving seat, and its upper and lower ends are respectively fixedly connected to the two clamping plates on the same side.

[0010] In a preferred embodiment, the precooling assembly includes an air-cooled box fixedly connected to the inside of the first cavity. The air-cooled box includes a flow pipe with its two ends fixedly connected. Several internal holes are opened at the upper and lower ends of the inner side of the air-cooled box. A cold air pump is fixedly connected to the bottom of the first cavity, and its output end is fixedly connected to the bottom of the air-cooled box.

[0011] In a preferred embodiment, the bottom of the inner side of the second cavity is filled with coolant, and the cooling assembly includes a spray nozzle fixedly connected to the upper and lower ends of the inner side of the second cavity, and a condenser fixedly connected to the bottom of the inner side of the second cavity.

[0012] In a preferred embodiment, several flow holes are provided at the adjacent ends of the two spray seats. The diameter of the flow holes gradually decreases towards the third cavity. A water pump is fixedly connected to the inside of the second cavity. A double-ended pipe is fixedly connected to the output end of the water pump, and its other end is fixedly connected to the two spray seats. An input pipe is fixedly connected to the input end of the water pump, which extends to the bottom of the second cavity.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This utility model, by setting up a side frame, lead screw, and clamping assembly, uses a transport mechanism to transport the mold to the support. When the mold is transported to the support, a two-way electric cylinder can drive two clamping plates to move in opposite directions in the slide. The clamping plates on both sides hold the mold, and the lead screw can drive the transfer seat and the mold to move in the cooling box for cooling. Finally, the mold is removed from the cooling box and placed on the transport structure on the other side. No manual loading and unloading is required, which improves the working efficiency of the equipment.

[0014] This utility model, by setting up a cooling box, a pre-cooling component, and a cooling component, allows the mold to pre-cool its outer side by inputting cold air into the air-cooling box through a cold air pump in the first cavity. Coolant is then input into two spray nozzles through a water pump in the second cavity and sprayed directly onto the mold through flow holes, ensuring efficient and uniform cooling. The reduced diameter of the flow holes gradually reduces the cooling effect, preventing the rearview mirror from breaking due to a rapid drop in mold temperature. Finally, the mold is allowed to cool naturally to room temperature through the third cavity, thus improving the cooling effect of the equipment. Attached Figure Description

[0017] The present invention will be further described below with reference to the embodiments.

[0018] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention; the conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0019] Please see Figures 1-4This utility model provides a cooling device for a hot-bent rearview mirror, including a processing table 1. A cooling box 2 is fixedly connected to the top of the processing table 1. Side frames 4 are fixedly connected to the front and rear ends of the top of the processing table 1. The cooling box 2 passes through the inner side of the side frames 4. A clamping assembly is slidably connected to the inner side of the side frames 4. A lead screw 6 is rotatably connected to the inner side of the side frames 4. The clamping assembly is threadedly connected to the outer side of the lead screw 6. A transport mechanism 3 is fixedly connected to both sides of the top of the processing table 1. A support 16 is fixedly connected to the top of the processing table 1 inside the two clamping assemblies. A forward and reverse motor is fixedly connected to the outside of the side frame 4, and its output end is fixedly connected to the lead screw 6 on the same side. The clamping assembly includes a sliding seat 5 slidably connected to the inside of the side frame 4. The sliding seat 5 is threadedly connected to the outside of the lead screw 6. The cooling box 2 has an inner groove for the movement of the two sliding seats 5. The upper and lower ends of the adjacent sides of the two sliding seats 5 are provided with sliding grooves 8. The inner side of the sliding grooves 8 is slidably connected to a clamping plate 9. A bidirectional electric cylinder 10 is fixedly connected to the inside of the sliding seat 5, and its upper and lower ends are fixedly connected to the two clamping plates 9 on the same side, respectively. The two forward and reverse motors are synchronous motors.

[0020] After hot bending, the rearview mirror, along with the external mold, is transported by the existing external equipment to the transport mechanism 3 on the left. The transport mechanism 3 transports the mold to the support 16, activates the bidirectional electric cylinders 10 on both sides, pushes the corresponding clamping plates 9 to slide along the slide groove 8, clamps the two sides of the mold, and simultaneously activates the positive and negative motors on both sides to drive the lead screw 6 to rotate, so that the shift seat 5 moves along the side frame 4 into the cooling box 2.

[0021] The bidirectional electric cylinder 10 can push two corresponding clamping plates 9 along the slide 8 towards the mold until the clamping plates 9 are tightly attached to the mold. The clamping operation is completed by the clamping components on both sides. The lead screw 6 can drive the transfer seat 5 to move along the side frame 4, so that the mold moves together with the transfer seat 5 in the cooling box 2 for cooling. During the cooling process, the mold is always firmly fixed by the clamping components to avoid the mold displacement or deformation caused by temperature changes during the cooling process. After the cooling operation is completed, the transfer seat 5 can remove the mold from the cooling box 2. Finally, the transport mechanism 3 on the other side can transport and unload the cooled mold. The whole process does not require manual intervention and fully realizes automated loading and unloading. It not only improves work efficiency, but also reduces the errors and safety hazards that may be caused by manual operation, and improves the automation level and stability of the entire production process.

[0022] Please see Figures 1-4The cooling box 2 includes three chambers, namely, a first chamber 11, a second chamber 12, and a third chamber 13, which are opened sequentially from left to right on the inner side. A pre-cooling component is fixedly connected to the inner side of the first chamber 11, and a cooling component is fixedly connected to the inner side of the second chamber 12. The pre-cooling component includes an air-cooled box 14 fixedly connected to the inner side of the first chamber 11. The air-cooled box 14 includes a flow pipe 15 with its two ends fixedly connected. Several internal holes are opened at the upper and lower ends of the inner side of the air-cooled box 14. A cold air pump is fixedly connected to the bottom of the first chamber 11, and its output end is fixedly connected to the bottom of the air-cooled box 14. The second chamber 11... The inner bottom of cavity 2 is filled with coolant. The cooling assembly includes a spray seat 17 fixedly connected to the upper and lower ends of the inner side of cavity 2. A condenser is fixedly connected to the inner bottom of cavity 2. Several flow holes 18 are opened at the adjacent ends of the two spray seats 17. The diameter of the flow holes 18 gradually decreases towards cavity 3. A water pump 7 is fixedly connected to the inner side of cavity 2. A double-ended pipe is fixedly connected to the output end of the water pump 7. Its other end is fixedly connected to the two spray seats 17. An input pipe is fixedly connected to the input end of the water pump 7, which extends to the bottom of cavity 2.

[0023] After the mold enters cavity 11, the forward and reverse motors stop, and the cold air pump is started to deliver cold air through the flow pipe 15 to the upper and lower ends of the air-cooling box 14. The air is then blown evenly onto the mold surface through the inner hole to lower its temperature for pre-cooling. Then, the forward and reverse motors drive the mold to move to cavity 12, and the water pump 7 is started to draw the coolant from the bottom of cavity 12 into the cavity through the input pipe. The coolant is then delivered to two sprayers 17 through the double-ended pipe and sprayed onto the mold surface through the flow holes 18 of the sprayers 17. At the same time, the mold moves slowly, cooling the mold through the gradually decreasing diameter flow holes 18. The condenser works to cool the coolant, ensuring that the temperature of the coolant is always kept at a low level, until the mold moves to cavity 13. The mold is cooled to a suitable temperature in cavity 13. Then, the forward and reverse motors drive one end of the mold to move onto the right-side transport mechanism 3. The bidirectional electric cylinder 10 drives the clamping plate 9 to release the mold, and the transport mechanism 3 transports the mold to the subsequent external existing working equipment.

[0024] Cooling box 2 is divided into three independent chambers, each with a different cooling task to ensure the orderly progress of the cooling process. A cold air pump delivers cooled air to the air-cooled box 14. This cold air passes through specially designed flow pipes 15 and internal holes within the air-cooled box 14, forming a uniform airflow that directly acts on the outer side of the mold. This reduces the temperature of the mold surface, allowing it to smoothly transition from a high-temperature state to a relatively low temperature range. This effectively reduces the temperature difference between the mold and the cooling medium and prevents stress concentration on the mold surface caused by a sudden temperature drop. The diameter of the flow holes 18 inside the spray holder 17 gradually decreases from chamber 11 to chamber 13. When the coolant is sprayed out from the flow hole 18, it forms a uniform liquid flow that is directly sprayed onto the mold surface. This not only ensures that the coolant can efficiently cover every corner of the mold, but also gradually reduces the cooling effect through the gradually decreasing diameter of the flow hole 18. This effectively avoids a rapid drop in mold temperature, thereby reducing the risk of rearview mirror glass breakage due to excessive temperature difference and ensuring the safety and stability of the cooling process. In the third cavity 13, the mold can gradually cool to room temperature in this relatively stable environment, providing a buffer stage for the mold so that the internal and surface temperatures can reach a uniform balance. This further reduces the generation of residual stress and ensures the quality and performance of the rearview mirror product.

[0025] The working principle and usage process of this utility model: After hot bending, the rearview mirror, along with the external mold, is transported by external equipment to the left-side transport mechanism 3. The transport mechanism 3 transports the mold to the support 16. The two-way electric cylinders 10 on both sides are activated, pushing the corresponding clamping plates 9 to slide along the slide groove 8, clamping both sides of the mold. Simultaneously, the two-way motors on both sides are activated, driving the lead screw 6 to rotate, causing the shift seat 5 to move along the side frame 4 into the cooling box 2. After the mold enters the first cavity 11, the motors on both sides stop, and the cold air pump is activated, delivering cold air through the flow pipe 15 to the upper and lower ends of the air-cooling box 14. The cold air is then evenly blown onto the mold surface through the inner hole to lower its temperature for pre-cooling. Afterward, the motors on both sides drive the mold to move. Upon reaching cavity 12, water pump 7 is activated to draw coolant from the bottom of cavity 12 into the cavity through the input pipe. The coolant is then transported through a double-ended pipe to two spray nozzles 17, where it is sprayed onto the mold surface through the flow holes 18. Simultaneously, the mold moves slowly, cooling itself through the gradually decreasing diameter flow holes 18. The condenser operates to cool the coolant, ensuring that its temperature remains consistently low until the mold moves to cavity 13. Once the mold has cooled to a suitable temperature in cavity 13, the forward and reverse motors drive one end of the mold to move onto the right-side transport mechanism 3. The bidirectional electric cylinder 10 drives the clamping plate 9 to release the mold, and the transport mechanism 3 transports the mold to the subsequent external working equipment.

[0026] In the above scheme, it should be noted that: the transport mechanism 3 in this application is an existing "conveyor belt" structure, and the transport mechanism 3, the bidirectional electric cylinder 10, the forward and reverse motor, the cold air pump, the water pump 7 and the condenser are all existing products. Furthermore, the specific structure, electrical connection method (circuit layout) and working principle of the transport mechanism 3, the bidirectional electric cylinder 10, the forward and reverse motor, the cold air pump, the water pump 7 and the condenser are all existing publicly disclosed technical means, and will not be described in detail here. It should also be noted that the cooling equipment of this application can also be used with an existing controller (or control system) to regulate the operating status of the transport mechanism 3, the bidirectional electric cylinder 10, the forward and reverse motor, the cold air pump, the water pump 7 and the condenser. The telecommunication connection and control methods between the controller (or control system) and the transport mechanism 3, the bidirectional electric cylinder 10, the forward and reverse motor, the cold air pump, the water pump 7 and the condenser all adopt existing publicly available technical means, which will not be described in detail here.
