[0002] A glass hot bending machine is a device used to process glass workpieces into various shapes as needed. In order to produce high-quality glass products, people have designed and manufactured various types of hot bending forming machines. The hot bending glass production process includes steps such as heating, forming, and cooling. The glass hot bending machine integrates these steps into one machine, saving labor costs.

[0003] A simplified version of a fully automatic glass hot bending forming machine is disclosed in patent document CN220642904U. The machine includes a base on which a feeding mechanism, a forming assembly, and a cooling section are sequentially arranged. The forming assembly includes a main furnace cavity, within which a preheating section, a forming section, and a slow cooling section are sequentially arranged. The preheating section includes preheating units, including end preheating units and middle preheating units. The cooling assembly includes a cooling cavity, with an upper cooling plate lifting device on the top plate of the cooling cavity. An upper cooling plate is located at the bottom of the upper cooling plate lifting device. In this design, the middle preheating unit maintains a fixed height during operation and does not undergo lifting or lowering motion. The upper cooling plate in the cooling assembly also adopts a fixed height, replacing the existing structure that uses a single actuator to control the lifting and lowering of the upper cooling plate. These two measures effectively reduce manufacturing costs and simplify the machine structure.

[0004] However, the aforementioned machine consists of multiple workstations. Sometimes, it is necessary to make samples during production. If a single sample is made using this machine, it takes a long time, consumes a lot of electricity, wastes machine resources, and increases production costs. Summary of the Invention

[0005] The present invention aims to solve the technical problem of resource waste when using existing machines to produce samples.

[0006] To solve the above-mentioned technical problems, this utility model provides a single-station hot bending forming machine, including a frame, a forming component on the frame, and an inlet / outlet platform component for supporting the mold on one side of the forming component; the forming component includes a forming furnace body, with a first mold inlet / outlet on the side of the forming furnace body near the inlet / outlet platform component; an inlet pushing device is provided on the side of the inlet / outlet platform component to push the mold on the inlet / outlet platform component into the forming furnace body; an outlet pushing device is provided on the frame or the forming furnace body to push the mold inside the forming furnace body onto the inlet / outlet platform component; the forming component also includes a lower forming component located at the bottom of the forming furnace body; and an upper forming component corresponding to the lower forming component is provided at the top of the forming furnace body. A cooling box assembly is provided above the inlet / outlet platform component; the cooling box assembly includes a cooling box body that communicates with the forming furnace body, a second mold inlet / outlet is provided on the side of the cooling box body adjacent to the first mold inlet / outlet, a liftable cooling component is provided at the top of the cooling box body; and an outlet pushing device is provided on the side of the cooling box body opposite to the second mold inlet / outlet.

[0007] This scheme places the sample to be produced on the mold entry and exit platform. The sample enters and exits the molding furnace through the furnace entry and exit pushing devices. After exiting the furnace, the sample first enters the cooling box and is cooled by the cooling components. Then, the cooled sample is pushed out of the cooling box by the box exit pushing components, thus completing the sample production.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] like Figures 1 to 6 As shown, a single-station hot bending forming machine includes a frame 1, a forming component 2 on the frame 1, and an inlet / outlet platform component 3 for supporting the mold on one side of the forming component 2. The forming component 2 includes a forming furnace body 21, and a first mold inlet / outlet 211 is provided on the side of the forming furnace body 21 near the inlet / outlet platform component 3. An inlet pushing device 23 for pushing the mold on the inlet / outlet platform component 3 into the forming furnace body 21 is provided on one side of the inlet / outlet platform component 3. An outlet pushing device 22 for pushing the mold in the forming furnace body 21 onto the inlet / outlet platform component 3 is provided on the frame 1 or the forming furnace body 21. The forming component 2 also includes a lower forming component 25 located at the bottom of the forming furnace body 21. An upper forming component 24 corresponding to the lower forming component 25 is provided on the top of the forming furnace body 21.

[0018] During the manufacturing process, the workpiece sample requiring hot bending is pushed into the forming furnace body 21 by the furnace inlet pushing device 23. At this time, the first inlet and outlet door plate 26 is raised by the first door plate cylinder 27. After the sample enters the forming furnace body 21, the first door plate cylinder 27 lowers the first inlet and outlet door plate 26, so that the forming furnace body 21 is in a closed state. The sample is hot-bent by the cooperation of the upper forming component 24 and the lower forming component 25. After the sample in the forming furnace body 21 is hot-bent, the first door plate cylinder 27 raises the first inlet and outlet door plate 26, and the furnace outlet pushing device 22 pushes the sample out of the forming furnace body 21. In this embodiment, both the furnace outlet pushing device 22 and the furnace inlet pushing device 23 are controlled by cylinders. The cylinder push rod is connected to a push block, which pushes the mold 6.

[0019] like Figures 5 to 6 In this embodiment, a cooling box assembly 4 is provided above the mold entry and exit platform assembly 3; the cooling box assembly 4 includes a cooling box 41, which is connected to the molding furnace body 21. A second mold entry and exit 411 is provided on the side of the cooling box 41 adjacent to the first mold entry and exit 211. A second entry and exit door plate 45 is provided at the second mold entry and exit 411. A second door plate cylinder 44 is connected above the second entry and exit door plate 45, and the lifting and lowering of the second entry and exit door plate 45 is controlled by the second door plate cylinder 44.

[0020] A liftable cooling assembly 42 is provided on the top of the cooling box 41; the cooling assembly 42 includes a cold water plate 421, which is located inside the cooling box 41. The cold water plate 421 has a first water inlet 4211 and a first water outlet 4212. The first water outlet 4212 of the first water inlet 4211 extends out of the cooling box 41 and is connected to a water pipe. A cooling cylinder is also provided on the cooling box 41. The push rod of the cooling cylinder extends into the cooling box 41 and is connected to the cold water plate 421.

[0021] The sample that has undergone hot bending treatment in the molding furnace body 21 is pushed into the cooling box 41 by the furnace pusher 22. The cold water plate 421 located at the top of the box is lowered by the cooling cylinder. At this time, the cold water plate 421 is attached to the mold 6. Since water is injected into the channel of the cold water plate 421 through the first water inlet 4211 through the water pipe and then discharged from the first water outlet 4212, the liquid in the cold water plate 421 is always kept at a low temperature. The liquid in the cold water plate 421 cools the mold 6.

[0022] like Figures 7 to 8 As shown, in this embodiment, a first cooling passage 412 is provided in the wall of the cooling box 41, and a second water inlet 4121 and a second water outlet 4122 are provided at both ends of the first cooling passage 412. A second cooling passage 36 is provided in the part of the mold platform assembly 3 located inside the cooling box 41, and a third water inlet 361 and a third water outlet 362 are provided at both ends of the second cooling passage 36. When the mold 6 in the molding furnace 21 is pushed into the cooling box 41, the high temperature of the mold 6 will heat the air inside the cooling box 41. The hot air inside the box comes into contact with the box wall, and the liquid in the first cooling passage 412 is continuously replaced by the second water inlet 4121 and the second water outlet 4122 inside the box wall. In this process, the liquid in the first cooling passage exchanges heat with the hot air inside the cooling box 41 through the cooling box 41, thereby cooling the air inside the cooling box.

[0023] Meanwhile, the mold entry and exit platform assembly 3 includes an mold entry and exit platform 30. The portion of the mold entry and exit platform 30 located inside the cooling box 41 is provided with a second cooling passage 36. Through the third water inlet 361 and the third water outlet 362, the water in the second cooling passage 36 is kept at a low temperature. Since the mold entry and exit platform 30 is in contact with the bottom of the mold 6, the bottom of the mold 6 is cooled. As the liquid flows continuously in the passage, the temperature of the mold entry and exit platform 30 is kept within a constant range, which increases the cooling effect on the mold 6.

[0024] An entry mold pusher block 31 is provided on the entry mold platform 30, and a pusher block through slot 32 is provided on the entry mold platform 30. An entry mold cylinder 33 is provided at the bottom of the entry mold platform 30. The entry mold pusher block 31 is connected to a cylinder connecting block 34, which passes through the pusher block through slot 32 and is connected to the entry mold cylinder 33. A guide plate 35 is also provided on the entry mold platform 30. An exit mold pushing device 43 is provided on the side of the cooling box 41 opposite to the second mold inlet and outlet 411. The entry mold pusher block 31 and the exit mold pushing device 43 are controlled by cylinders to realize automated operation and reduce manual operation costs.

[0025] like Figures 1 to 2 As shown, a first viewing window 212 is provided on both sides of the furnace wall adjacent to the first mold inlet and outlet 211 on the molding furnace body 21, through which the internal condition of the molding furnace body 21 can be observed; a second viewing window 413 is provided on the top of the cooling box 41, through which the internal condition of the cooling box 41 can be observed; during the molding and cooling processes, the mold 6 is in a closed state, and the first viewing window 212 and the second viewing window 413 facilitate the operator to observe the specific condition of the sample in the closed environment, thereby deciding on the next operation.

[0026] In this embodiment, protective covers 5 are provided above the furnace discharge pushing device 22, the furnace infeed pushing device 23, and the box discharge pushing device 43; the protective covers 5 prevent bumps and collisions, thereby avoiding damage to the furnace discharge pushing device 22, the furnace infeed pushing device 23, and the box discharge pushing device 43.

[0027] In this embodiment, an overall control system is provided in the frame 1, and an operating platform 11 is provided on the frame 1. The operating platform 11 is connected to the control system in the frame 1. The operator only needs to input instructions through the operating platform 11 to operate the whole machine through the control system, which facilitates the operation of the staff.

[0028] The above structure places the sample to be made on the mold entry and exit platform 30. The sample enters and exits the molding furnace 21 through the furnace entry push device 23 and the furnace exit push device 22. After exiting the furnace, the sample first enters the cooling box 41 and is cooled by the cooling component 42. Then, the cooled sample is pushed out of the cooling box 41 by the box exit push device 43, thus completing the sample making. The whole device occupies relatively little space, and one operator can complete the making of a single sample. It does not require the use of a machine with multiple workstations, saving machine resources, shortening the sample making time, and reducing costs.
