Description

Technical Field

[0001] This utility model belongs to the field of glass manufacturing technology, and specifically relates to a glass product forming equipment. Background Technology

[0002] Irregularly shaped quartz glass refers to quartz glass products with non-standard geometric shapes (such as complex curved surfaces, irregular cavities, special apertures, irregular contours, etc.). They are all made from quartz grinding wheels as raw materials and processed through a series of steps (such as cutting, rough grinding, fine grinding, external cylindrical grinding, chamfering, cleaning, etc.). For example: (1) Ring-shaped quartz glass products: The quartz ball is cut to obtain multiple arc-shaped strip structures, which are then welded together to form a ring structure. The ring structure is then polished, chamfered, and cleaned to obtain the final product. (2) Regular-shaped products with a hollow center: The plate-shaped or rod-shaped quartz ball is cut into a regular-shaped primary product, and then a through hole is processed in the center of the primary product to form a secondary product. Finally, the final product is obtained through grinding, chamfering, cleaning, etc.

[0003] It is evident that the traditional processing of irregularly shaped quartz glass with a hollow center is cumbersome, has a low yield, and consumes a significant amount of time for raw materials and manual labor, resulting in high costs and poor product consistency. Furthermore, the processing of irregularly shaped quartz glass is greatly affected by the skill level of manual heat treatment, and chipping is likely to occur at the inner and outer edges of the product, leading to an unsatisfactory product qualification rate. Utility Model Content

[0004] This utility model provides a glass product forming equipment, which aims to solve the technical problems of traditional irregular quartz glass processing, such as cumbersome process, low yield, high processing cost, poor product consistency, reliance on operator skill, and unsatisfactory product qualification rate.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a glass product forming equipment, comprising: The main body has an upper hoisting channel and a lower heating zone inside, and the hoisting channel is connected to the heating zone; A hoisting structure, located at the top of the main body, is used to hoist the original weight through the hoisting channel into the heating zone; A molding structure is located within the heating zone, and the molding structure includes an annular outer molding ring and an inner molding block fixed inside the outer molding ring; A fastener, connected to the inner forming block and extending beyond the top of the inner forming block, is used to fix the original weight.

[0006] In one possible implementation, the molding structure further includes a base with a slot, and the outer molding ring is detachably engaged with the slot.

[0007] In one possible implementation, the outer forming ring is a ring structure composed of multiple sheets.

[0008] In one possible implementation, the base is provided with a slot that mates with the fastener.

[0009] In one possible implementation, the fastener penetrates the inner molded block and engages with the slot; Alternatively, the fixing member includes a first fixing rod and a second fixing rod, the first fixing rod being connected to the top of the inner molding block for fixing the original weight, and the second fixing rod being connected to the bottom of the inner molding block and engaging with the slot.

[0010] In one possible implementation, the glass forming equipment further includes: A lifting structure is located below the main body. The lifting structure has a lifting part that extends into the heating zone and is fixed to the bottom of the base.

[0011] In one possible implementation, the bottom of the base is provided with a mating groove that cooperates with the lifting part.

[0012] In one possible implementation, the cross-sectional area of ​​the inner forming block gradually decreases from bottom to top.

[0013] In one possible implementation, the subject further includes: An insulation layer is located in the heating zone and surrounds the outer periphery of the molded structure; A heating element is embedded in the insulation layer, and the heating element is used to heat the molded structure.

[0014] In one possible implementation, the main body is provided with an observation window at the position corresponding to the heating zone.

[0015] In this embodiment, compared with the prior art, the height of the original molding blanks may vary depending on their size. After the original molding blank is fixed on the inner forming block, part of it may be located within the lifting channel. The lifting channel can accommodate original molding blanks of different sizes for forming, especially for the production of large-sized glass products. To accommodate original molding blanks of different sizes, the lifting channel has a certain height in the vertical direction, making it convenient to place the original molding blank into the lifting structure. This facilitates operation, and the blank can be removed after forming. The space between the inner forming block and the outer forming ring encloses a forming cavity. The molten glass flows into the forming cavity and cools to solidify. Compared with the traditional process that requires cutting and splicing to form, this forming process has fewer steps, ensures forming quality, and does not generate cutting waste, thus reducing manufacturing costs.

[0024] Please refer to the following: Figures 1 to 4 The glass product forming equipment provided by this utility model will now be described. The glass product forming equipment includes a main body 10, a lifting structure 20, a forming structure 30, and a fixing member 40. The main body 10 has a lifting channel 11 located at the top and a heating zone 12 located at the bottom, and the lifting channel 11 is connected to the heating zone 12. The lifting structure 20 is located at the top of the main body 10 and is used to lift the raw material 60 through the lifting channel 11 into the heating zone 12. The forming structure 30 is located in the heating zone 12 and includes an annular outer forming ring 31 and an inner forming block 32 fixed inside the outer forming ring 31. The fixing member 40 is connected to the inner forming block 32 and extends out of the top of the inner forming block 32 to fix the raw material 60.

[0025] Optionally, the cross-section of the outer forming ring 31 in the forming structure 30 can be triangular, rectangular, circular, hexagonal, or other shapes, depending on the production requirements; the cross-section of the inner forming block 32 can also be triangular, rectangular, circular, hexagonal, or other shapes. The cross-sections of the outer forming ring 31 and the inner forming block 32 can be the same or different. When the cross-sectional shapes of the inner forming block 32 and the outer forming ring 31 are the same, the cross-sectional size of the inner forming block 32 is proportional to the cross-sectional size of the outer forming ring 31.

[0026] To ensure the quality of the glass products after molding, the main body 10 is provided with an air inlet 13 and an air outlet 14. The air inlet 13 is connected to the hoisting channel 11, and the air outlet 14 is connected to the heating zone 12. During the heating process, inert gas is introduced into the main body 10 through the air inlet 13 and then flows out from the air outlet 14. This can achieve inert gas protection and remove volatile impurities, thus preventing bubbles from forming in the glass products.

[0027] The glass forming equipment provided in this embodiment uses a glass blank 60 which is fed into the heating zone 12 inside the main body 10 through the hoisting structure 20 and fixed to the top of the inner forming block 32 by the fixing member 40. The forming structure 30 is heated by the heating zone 12. At this time, inert gas is continuously circulated through the air inlet 13 and the air outlet 14 for protection. During the heating process, the blank 60 fixed on the inner forming block 32 melts and flows into the space between the inner forming block 32 and the outer forming ring 31. After cooling, it forms a glass product.

[0028] Compared with the prior art, the glass forming equipment provided in this embodiment allows for different sizes of raw materials 60 with varying heights. After the raw material 60 is fixed on the inner forming block 32, a portion of it may be located within the lifting channel 11. The lifting channel 11 can accommodate raw materials 60 of different sizes for forming, especially suitable for the production of large-sized glass products. To accommodate raw materials 60 of different sizes, the lifting channel 11 has a certain height in the vertical direction, facilitating the placement of the raw material 60 via the lifting structure 20. This makes operation convenient, and the raw material 60 can be removed via the lifting structure 20 after forming. The space between the inner forming block 32 and the outer forming ring 31 encloses a forming cavity. Molten glass flows into the forming cavity and cools to solidify. Compared with the traditional process that requires cutting and splicing for forming, this forming process has fewer steps, ensures forming quality, and eliminates cutting waste, thus reducing manufacturing costs.

[0029] The aforementioned hoisting structure 20 can be a commonly used hoisting structure 20 in this field, such as a vacuum suction cup hoist, which uses a vacuum suction cup to adsorb the glass weight 60 and then uses a crane for hoisting.

[0030] In some embodiments, an improved implementation of the above-described molding structure 30 may employ, as follows: Figures 1 to 2 The structure shown. See also Figures 1 to 2 The molding structure 30 also includes a base 33, on which a slot is provided, and the outer molding ring 31 is detachably engaged with the slot.

[0031] The groove between the outer forming ring 31 and the base 33 facilitates the disassembly of the outer forming ring 31. After the molten glass cools and solidifies in the forming cavity, the glass product can be removed by removing the outer forming ring 31, which facilitates demolding.

[0032] As an improved implementation, slots of different shapes can be provided on the base 33 to facilitate the installation of different outer forming rings 31, thereby adapting to the production of molded products of different specifications. It should be noted that in the actual production process, if there are multiple slots, unused slots need to be filled in to avoid leaving marks on the bottom surface of the glass products.

[0033] Specifically, the outer forming ring 31 is a ring structure composed of multiple sheets. These sheets can be connected using flexible connections or by adjacent sheets abutting against each other, as long as the flow of molten glass is prevented. The outer forming ring 31, being composed of multiple sheets, can be easily arranged into any structure required for forming, further expanding the forming range of the equipment; and if any sheet is damaged, it can be easily replaced, reducing maintenance costs.

[0034] In some embodiments, an improved implementation of the base 33 described above can adopt the following approach: Figures 1 to 2 The structure shown. See also Figures 1 to 2The base 33 is provided with a slot that mates with the fixing member 40. The fixing member 40 is used to fix the original weight 60, but it is also connected to the base 33, which improves the stability of the fixing member 40 and prevents the original weight 60 from shifting due to shaking of the fixing member 40 during the heating and melting process. This ensures the relative positional accuracy of the original weight 60 and the forming structure 30, and ensures that the centers of the original weight 60, the inner forming block 32 and the outer forming ring 31 are aligned, thereby ensuring the dimensional accuracy and forming consistency of the glass products.

[0035] Specifically, there are two ways to connect the fastener 40 to the base 33: The fastener 40 penetrates the inner molded block 32 and mates with the slot; Alternatively, the fastener 40 includes a first fixing rod 41 and a second fixing rod 42. The first fixing rod 41 is connected to the top of the inner molding block 32 to fix the original weight 60, and the second fixing rod 42 is connected to the bottom of the inner molding block 32 and mates with the slot.

[0036] When the fastener 40 passes through the inner molding block 32 and engages with the slot, the fastener 40 is an integral structure. The inner molding block 32 and the original weight 60 are fixed by the same fastener 40, which has good integrity, high structural strength, and simplifies the installation steps. When the fixing component 40 includes a first fixing rod 41 and a second fixing rod 42, the first fixing rod 41 is used to fix the original weight 60, and the second fixing rod 42 is used to fix the inner forming block 32. Their positions overlap vertically, ensuring the consistency of the center of the inner forming block 32 and the original weight 60, thereby improving the forming accuracy.

[0037] It should be noted that the bottom of the original weight 60 has a groove into which the fixing member 40 can be inserted. Therefore, when the lifting structure 20 lifts the original weight 60 into the heating zone, it is placed directly on the fixing member 40, so that the fixing member 40 is in the groove at the bottom of the original weight 60, thus fixing the original weight 60 on the fixing member 40.

[0038] In some embodiments, an improved implementation of the above-described glass product forming equipment may employ, as follows: Figure 1 The structure shown. See also Figure 1 The glass product forming equipment also includes a lifting structure 50, which is located below the main body 10. The lifting structure 50 has a lifting part 51 that extends into the heating zone 12 and is fixed to the bottom of the base 33.

[0039] Optionally, the lifting structure 50 can be driven by a cylinder to lift the lifting part 51. Since the lifting part 51 is located in the heating zone 12, it needs to be made of a material that can withstand the high temperature in the heating zone 12.

[0040] In this embodiment, the lifting part 51 can drive the forming structure 30 to move up and down within the heating zone 12. When the original weight 60 is hoisted into the heating zone 12, the lifting part 51 can move upward to connect with the original weight 60, thereby improving hoisting efficiency. During the heating process, the lifting part 51 can drive the forming structure 30 to move up and down repeatedly within the heating zone 12, thereby ensuring that the molten glass in the forming structure 30 is heated evenly, ensuring its fluidity, reducing the generation of internal bubbles, and improving the quality of the final glass product.

[0041] In some embodiments, a specific connection method between the base 33 and the lifting part 51 can be as follows: Figures 1 to 2 The structure shown. See also Figures 1 to 2 The bottom of the base 33 is provided with a mating groove that cooperates with the lifting part 51. The lifting part 51 can be a cylindrical structure that is fixed to the piston rod of the cylinder, and the corresponding mating groove can also be a circular groove. By engaging the lifting part 51 with the mating groove on the base 33, it is convenient for the base 33 and the lifting part 51 to be connected, simplifying the assembly process and reducing labor intensity.

[0042] In some embodiments, an improved implementation of the aforementioned internal molding block 32 may employ, as follows: Figures 1 to 4 The structure shown. See also Figures 1 to 4 The cross-sectional area of ​​the inner forming block 32 gradually decreases from bottom to top. The blank 60 is fixed at the top of the inner forming block 32. During the melting process of the blank 60, the molten glass flows downward under the action of gravity. When it falls onto the inner forming block 32, it will gradually flow along the outer peripheral surface of the inner forming block 32 to the space between the inner forming block 32 and the outer forming ring 31, and gradually fill the space between the inner forming block 32 and the outer forming ring 31. Finally, it cools and solidifies to form the final glass product. This structure can prevent molten glass from falling directly from a height to this location, which would cause air bubbles to be generated inside, and reduce defects such as air bubbles and incomplete filling.

[0043] At the same time, this structure can also form a draft angle after the glass product cools, which facilitates demolding and avoids damage to the inner cavity surface of the glass product during the demolding process.

[0044] In some embodiments, an improved implementation of the aforementioned body 10 may employ, as follows: Figure 1 The structure shown. See also Figure 1 The main body 10 also includes a heat insulation layer 15 and a heating element 16. The heat insulation layer 15 is located in the heating zone 12 and surrounds the outer periphery of the molded structure 30. The heating element 16 is embedded in the heat insulation layer 15 and is used to heat the molded structure 30.

[0045] It should be noted that the insulation layer 15 can be fixed on the inner wall of the main body 10 corresponding to the heating zone 12; or the insulation layer 15 can also be fixed on the base 33, spaced apart from the outer forming ring 31 and also spaced apart from the inner wall of the main body 10 corresponding to the heating zone 12.

[0046] In this embodiment, by setting the insulation layer 15, heat loss in the heating zone 12 can be avoided, thus improving energy utilization efficiency; the heating element 16 is embedded in the insulation layer 15, which can directly and uniformly heat the molded structure 30, avoiding the problem of uneven temperature in traditional heating methods, ensuring that the glass melt is heated evenly, reducing internal stress or cracking caused by local temperature differences, and improving product quality stability.

[0047] To further prevent heat loss from the heating zone 12, the bottom of the hoisting channel 11 is connected to the heating zone 12. An openable and closable insulation cover can be installed on the top of the hoisting channel 11. The insulation cover is only opened when there is a hoisting requirement and closed at other times to prevent heat from the heating zone 12 from being lost through the hoisting channel 11.

[0048] Specifically, the insulation layer 15 can be made of materials such as aluminum silicate cotton, and the heating element 16 is a structure commonly used in the field for heating glass cores 60, which is existing technology and will not be described in detail here.

[0049] In some embodiments, an improved implementation of the aforementioned body 10 may employ, as follows: Figure 1 The structure shown. See also Figure 1 The main body 10 is provided with an observation window 17 at the position corresponding to the heating zone 12. The observation window 17 facilitates real-time observation during the molding process and allows for manual intervention to control factors such as adding or removing material, air flow, and heating temperature.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
