Description

Technical Field

[0001] The present invention relates to the technical field of glass molding, and in particular to an open glass molding device and method. Background Art

[0002] In the production process of glass products, molding is a common technical means. During the processing and production, a glass molding device is required.

[0003] The glass molding device consists of a frame, a base, and a mold. The base is mounted on the frame, and the mold is vertically slidably connected to the frame and positioned above the base. The base is provided with a contoured groove, and a pressing head is located at the bottom of the mold. During the production process, workers first heat and soften the glass preform, then place the softened glass in the contoured groove. The mold then moves downward, allowing the pressing head to press down on the softened glass, which then forms a mold in conjunction with the contoured groove. Finally, the glass cools until it solidifies, resulting in a finished glass product.

[0004] However, during the production process of traditional glass molding devices, their bases and molds are usually directly exposed to the workshop environment, and the temperature of the workshop environment is difficult to control. Some glass products with higher process requirements are structurally unstable when they are just pressed and formed, and are easily affected by the ambient temperature, resulting in poor product quality.

DETAILED DESCRIPTION

[0029] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0030] Example 1

[0031] The embodiment of the present application discloses an open glass molding device, referring to Figure 1 、 Figure 2 and Figure 3 , comprising a temperature-controlled box 2, with a material port 21 provided on one side of the temperature-controlled box 2. A mold 3 is vertically slidably mounted on the inner top wall of the temperature-controlled box 2, and a pressure head 31 is provided at the bottom of the mold 3. A mounting plate 11 is welded to the outer wall of the temperature-controlled box 2 at the material port 21. A slide 4 for entering and exiting the material port 21 is horizontally and linearly slidably mounted on the mounting plate 11. A base 5 is provided on the slide 4. A contoured groove 51 is defined at the top of the base 5 for cooperating with the pressure head 31 to press the softened glass material. A baffle 6 for opening and closing the material port 21 is provided on the side of the slide 4 away from the temperature-controlled box 2. A first driving member 32 for driving the mold 3 is mounted on the temperature-controlled box 2, and a second driving member 41 for driving the slide 4 and the baffle 6 is provided on the mounting plate 11.

[0032] In the embodiment of the present application, a base 5 containing a glass softener is mounted on a slide 4; then the second slide 4 moves into the temperature control box 2, and the baffle 6 can block the material port 21; then, the mold 3 moves downward, so that the pressure head 31 can cooperate with the contoured groove 51 to press the glass softener into shape; after the glass softener is shaped, the mold 3 moves upward to expose the formed glass, and the temperature in the temperature control box 2 is gradually reduced so that the glass can be slowly cooled until the glass structure is stable; finally, the slide 4 moves out of the temperature control box 2, and the structurally stable formed glass can be taken out. The temperature range and cooling time in the temperature control box 2 are set by engineers after experiments. During the production process, the glass products are located in the temperature control box 2 and are not affected by the ambient temperature of the workshop, which has the effect of improving the production quality of glass products.

[0033] In the embodiment of the present application, the amount of glass softener used for molding is greater than that required for the actual product. The mold 3 moves downward to allow the pressing head 31 to press the glass softener downward and fill the contoured groove 51. During molding, a gap is left between the bottom of the mold 3 and the top of the base 5. This open glass molding device eliminates the need for workers to precisely control the amount of glass softener to match the actual product. Workers only need to ensure that the amount of glass softener is greater than that required for the actual product, allowing the excess glass softener to be squeezed from the contoured groove 51 into the gap. After the glass is formed and removed, the excess can be polished off.

[0034] The first driving member 32 includes a first driving cylinder, which is mounted on top of the temperature control box 2. The piston rod of the first driving cylinder faces vertically downward and is bolted to the mold 3. The second driving member 41 includes a second driving cylinder, which is mounted horizontally on the mounting plate 11. The piston rod of the second driving cylinder is connected to the baffle 6.

[0035] Furthermore, the base 5 is attached to the top of the slide 4, which is equipped with a first positioning member to limit the horizontal displacement of the base 5 relative to the slide 4. Outside the temperature-controlled chamber 2, a first conveyor 7 for transporting the base 5 loaded with softened glass and a second conveyor 8 for transporting the base 5 loaded with formed glass are installed. Between the first and second conveyors 7 and 8, a mounting frame 1 is installed, on which a transfer mechanism 9 for transferring the base 5 is mounted.

[0036] In this embodiment of the present application, the first conveyor 7 and the second conveyor 8 are chain-type conveyors. The base 5 loaded with the softened glass is transported by the first conveyor 7. A transfer mechanism 9 transfers the base 5 from the first conveyor 7 to the slide 4, allowing the slide 4 to transfer the softened glass into the temperature-controlled chamber 2 for molding. After the molded glass is removed from the temperature-controlled chamber 2, the transfer mechanism 9 transfers the base 5 loaded with the molded glass to the second conveyor 8 for subsequent processing. This eliminates the need for manual handling of the base 5 and glass, reducing labor intensity.

[0037] Reference Figure 4 The transfer mechanism 9 includes a rotating frame 91 and two clamping plates 92. The rotating frame 91 is coaxially mounted on the top of the mounting frame 1. A mounting frame 93 is vertically slidably mounted on the rotating frame 91. Two clamping plates 92 are horizontally slidably mounted on the mounting frame 93. A material-grabbing space for the base 5 to enter is left between the two clamping plates 92. Both clamping plates 92 are mounted with second positioning members for limiting the displacement of the base 5 relative to themselves. A third driving member (not shown) is mounted on the mounting frame 1 for driving the rotating frame 91 to rotate, and a fourth driving member 922 is mounted on the mounting frame 93 for driving the clamping plates 92 to move.

[0038] In the embodiment of the present application, the rotating frame 91 can rotate to move the installation frame 93 and pass over the installation plate 11, the first conveyor 7 and the second conveyor 8. The installation frame 93 moves downward and the base 5 can be clamped by two clamps 92 for subsequent transportation.

[0039] The third drive member includes a drive motor, which is mounted at the bottom of the mounting frame 1. The output shaft of the drive motor is in driving connection with the rotating frame 91. The drive motor used in this embodiment of the application has a reverse function. The fourth drive member 922 includes a third drive cylinder, which is mounted on the rotating frame 91. The piston rod of the third drive cylinder faces vertically downward and is connected to the mounting frame 93.

[0040] Specifically, the first positioning member includes a plurality of first positioning posts 42 integrally fixed to the top of the slide 4, and a plurality of first positioning slots 52 are defined on the bottom of the base 5 for plugging and mating with the first positioning posts 42. The second positioning member includes a plurality of second positioning posts 921 integrally fixed to the clamping plate 92, and a plurality of second positioning slots 53 are defined on the sidewall of the base 5 for plugging and mating with the second positioning posts 921 one by one.

[0041] In the embodiment of the present application, when the clamping plate 92 clamps the base 5 on the first conveyor 7, it is necessary to ensure that the multiple first positioning posts 42 can be inserted into the multiple first positioning grooves 52. Then, when the base 5 is placed on the slide 4, the multiple second positioning posts 921 are inserted into the multiple second positioning grooves 53. In this way, the position of the base 5 is ensured to remain unchanged each time the slide 4 enters the temperature control box 2.

[0042] In order to facilitate the first positioning column 42 to be inserted into the first positioning groove 52, the opening size of the first positioning groove 52 is larger than the size of its own inner bottom wall, and its own inner side wall is conical. The first positioning column 42 is set to a conical shape that matches the first positioning groove 52.

[0043] In order to facilitate the second positioning column 921 to be inserted into the second positioning groove 53, the opening size of the second positioning groove 53 is larger than the size of its own inner bottom wall, and its own inner side wall is also conical. The second positioning column 921 is set to a conical shape that matches the second positioning groove 53.

[0044] Reference Figure 5 A heating device 10 for heating the glass softening material is installed on the first conveyor 7. The heating device 10 includes a cover 101 installed on the first conveyor 7. The cover 101 is provided with a passage for the base 5 loaded with the glass softening material to pass through, and a heating coil 102 is installed on the top wall of the passage.

[0045] In the embodiment of the present application, the glass softener will continue to dissipate heat in the air. When being transported on the first conveyor 7, the heating coil 102 in the cover 101 can continuously heat the glass softener to reduce the heat loss of the glass softener, ensuring that it enters the temperature control box 2 and the temperature is maintained within the temperature range suitable for molding work.

[0046] In order to reduce the resistance caused by friction during the movement of the slide 4, multiple rollers 43 are rotatably arranged at the bottom of the slide 4. The slide 4 is vertically slidably connected to the baffle 6, and grooves 22 for accommodating multiple rollers 43 are opened on the inner bottom wall of the temperature control box 2.

[0047] In the embodiment of the present application, when the slide 4 moves into the temperature control box 2, the roller 43 can pass through the groove 22. At this time, the slide 4 moves down and overlaps the bottom wall of the temperature control box 2. The roller 43 enters the groove 22, which can avoid the roller 43 being damaged by the pressure during molding.

[0048] The temperature of the glass softener will affect its deformation state during molding. In order to facilitate the staff to timely observe the molding state of the glass softener in the profiling groove 51, a detection device 20 is provided in the temperature control box 2, and a display 201 for displaying the pressed shape of the glass softener detected by the detection device 20 is provided on the outer wall of the temperature control box 2.

[0049] In the embodiment of the present application, the detection device 20 is an X-ray detector, which can detect the shape of the glass in the contour groove 51 and display it on the display 201. If there is a gap between the glass and the inner wall of the contour groove 51, it indicates that the glass is unqualified and needs to be removed and re-softened in time.

[0050] In order to improve the production efficiency of glass products, a plurality of temperature control boxes 2 are arranged at intervals along the circumference of the mounting frame 1.

[0051] The operating principle of an open glass molding device according to an embodiment of the present application is as follows: a base 5 containing a glass softener is mounted on a slide 4; a second slide 4 then moves into a temperature-controlled box 2, with a baffle 6 blocking the material port 21; the mold 3 then moves downward, allowing the pressing head 31 to cooperate with the contoured groove 51 to press the glass softener into shape; after the glass softener is formed, the mold 3 moves upward to expose the formed glass, and the temperature in the temperature-controlled box 2 is gradually lowered to allow the glass to cool slowly until the glass structure stabilizes; finally, the slide 4 moves out of the temperature-controlled box 2, and the structurally stable formed glass can be removed. During the production process, the glass products are located in the temperature-controlled box 2 and are not affected by the ambient temperature of the workshop, thereby improving the production quality of the glass products.

[0052] Example 2

[0053] The present embodiment discloses an open glass molding method, which is applied to the open glass molding device disclosed in Example 1, and includes the following steps:

[0054] S1: Place the glass preform into a circulating softening furnace for heating and softening at a softening temperature between 900 and 1100°C (a circulating softening furnace is a commonly used glass softening furnace).

[0055] S2: placing the softened glass in the contoured groove 51 of the base 5 and placing the base 5 in the temperature control box 2;

[0056] S3: The mold 3 moves downward so that the pressing head 31 can cooperate with the contoured groove 51 to press the softened glass into shape;

[0057] S4: The pressed glass is kept in the molded state for at least 7 seconds to set its shape, after which the mold 3 is raised and the temperature in the temperature control box 2 is gradually lowered until the structure of the glass product is stable.

[0058] S5: Take out the glass product with a stable structure from the temperature control box 2.

[0059] In the embodiment of the present application, the temperature and cooling time in the temperature control box 2 can be obtained by engineers through multiple experiments. Glass products produced by different raw material ratios require different cooling times and temperature ranges.
