Description

Technical Field

[0001] This application relates to the field of automotive glass manufacturing technology, and more particularly to a hot bending forming mold. Background Technology

[0002] In the manufacturing process of automotive windshields, to transform flat glass into a curved windshield, a hot bending furnace and a hot bending forming mold are typically used to process the flat glass. Specifically, the flat glass is first placed on the forming frame of the hot bending forming mold, and then heated in the hot bending furnace to soften it. Due to gravity, the center of the flat glass falls freely from the hollow part of the forming frame, and the edges of the flat glass gradually conform to the edges of the forming frame, thus transforming the flat glass into a windshield.

[0003] In related technologies, hot bending forming molds include forming frames and bases. The forming frames are placed on the bases. Due to the large total height of the forming frames and bases, hot bending forming molds occupy a large space, making them inconvenient for storage and transportation. Utility Model Content

[0008] In some embodiments, the second connector is slidably fitted onto the first connector, the first connector having an inner connecting hole, the locking member passing through the inner connecting hole, and the locking member abutting against the second connector to restrict the second connector from moving toward the support member.

[0009] In some embodiments, the first connector has an inner connecting hole, the second connector has an outer connecting hole, and the locking member passes through the inner connecting hole and the outer connecting hole.

[0010] In some embodiments, the end of the first connector away from the support member is provided with a slot, and the second connector is detachably held in the slot to achieve a detachable connection between the first connector and the second connector.

[0011] In some embodiments, the forming frame includes a fixed frame and a forming frame arranged along a first direction.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0039] References to "one embodiment", "some embodiments", or "an embodiment" in the specification of this application mean that a particular feature, structure, or characteristic described in connection with that embodiment is included in one or more embodiments of this application. Thus, statements such as "in one embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments", etc. that appear at different places in this specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized. Additionally, in one or more embodiments, the particular features, structures, or characteristics may be combined in any suitable manner.

[0040] To illustrate the technical solution of this application, the following will be described with reference to specific drawings and embodiments.

[0041] In the related art, a hot bending forming die includes a forming frame and a base, and the forming frame is disposed on the base. Due to the relatively large total height of the forming frame and the base, the hot bending forming die occupies a large space, which is not convenient for storage and transportation.

[0042] To solve the above problems, this application provides a hot bending forming die, which can solve the problem that the hot bending forming die in the related art occupies a large space and is not convenient for storage and transportation.

[0043] Please refer to Figures 1 to 6 , an embodiment of this application provides a hot bending forming die 100, including a base 10 and a forming frame 20 that are arranged and connected along the first direction. The forming frame 20 can also be separated from the base 10 to increase the overlapping part of the base 10 and the forming frame 20 in the first direction.

[0044] The first direction can be the Z direction in the figure, and the first direction can be the height direction of the hot bending forming die 100. The forming frame 20 is used to carry the planar glass, and the planar glass is placed on the forming frame 20 during use. The base 10 and the forming frame 20 are detachably connected, such as by snap connection, magnetic connection, bolt connection, or screw connection to achieve detachable connection.

[0045] Please specifically refer to Figure 3 , when the base 10 and the forming frame 20 are connected, the overlapping part of the base 10 and the forming frame 20 in the first direction is less or there is no overlapping part. At this time, the size of the hot bending forming die 100 in the first direction is D1.

[0046] Please specifically refer to Figure 4 , when the base 10 and the forming frame 20 are separated, the overlapping part of the base 10 and the forming frame 20 in the first direction is larger. At this time, the size of the hot bending forming die 100 in the first direction is D2, and D2 < D1, so that the size of the hot bending forming die 100 in the first direction can be reduced.

[0047] As can be seen from the above, the hot bending forming mold 100 provided in this application embodiment includes a base 10 and a forming frame 20 arranged and connected along the first direction, and the forming frame 20 can also be separated from the base 10 to increase the overlapping part of the base 10 and the forming frame 20 in the first direction. Therefore, when it is necessary to store and transport the hot bending forming mold 100, the forming frame 20 can be separated from the base 10 to increase the overlapping part of the base 10 and the forming frame 20 in the first direction, thereby reducing the size of the hot bending forming mold 100 in the first direction, that is, reducing the space occupied by the hot bending forming mold 100 in the first direction, which is convenient for storage and transportation.

[0048] In this embodiment, the base 10 includes a support member 11 and a plurality of first connectors 12, the first connectors 12 being connected to the support member 11.

[0049] The forming frame 20 includes a forming component 201 and a plurality of second connecting components 202. The second connecting components 202 are connected to the forming component 201 and are correspondingly arranged with the first connecting components 12. The forming component 201 is located between two of the first connecting components 12 in a second direction, and the first connecting components 12 and the second connecting components 202 are detachably connected. The second direction is perpendicular to the first direction and can be along the X direction in the figure.

[0050] By adopting the above scheme, the structure of the hot bending forming mold 100 can be made simpler, and the base 10 and the forming frame 20 can be detachably connected more easily. Furthermore, after the forming frame 20 is separated from the base 10, the overlapping part of the base 10 and the forming frame 20 in the first direction can be increased.

[0051] Optionally, the first connector 12 and the second connector 202 can be detachably connected by means of snap-fit, magnetic connection, bolt connection, or screw connection. Four of each type of connector are provided.

[0052] The second connector 202 is slidably nested with the first connector 12, and the sliding direction of the second connector 202 relative to the first connector 12 is parallel to the first direction; the hot bending forming mold 100 also includes a locking member 30, and the first connector 12 and the second connector 202 are detachably connected through the locking member 30.

[0053] This configuration allows for a relatively convenient detachable connection between the first connector 12 and the second connector 202.

[0054] Specifically, the second connector 202 is slidably sleeved on the first connector 12. The first connector 12 is provided with an inner connecting hole 121. The locking member 30 passes through the inner connecting hole 121 and abuts against the second connector 202 to restrict the second connector 202 from moving towards the support member 11.

[0055] With this configuration, simply rotating the locking member 30 in different directions relative to the second connector 202 will cause the locking member 30 to abut against the first connector 12 and to separate the locking member 30 from the first connector 12.

[0056] Optionally, the locking member 30 is provided with a locking nut (not shown in the figure) and the two are threaded together, with the locking nut abutting against the second connecting member 202.

[0057] This configuration prevents the locking member 30 from rotating freely and separating from the first connector 12 after the locking member 30 is rotated relative to the second connector 202 and pressed against the first connector 12.

[0058] In other embodiments, the first connector 12 has an inner connecting hole 121, and the second connector 202 has an outer connecting hole (not shown in the figure). The locking member 30 passes through the inner connecting hole 121 and the outer connecting hole. Both the inner connecting hole 121 and the outer connecting hole can be through holes or threaded holes, or one of the inner connecting hole 121 and the outer connecting hole can be a through hole and the other can be a threaded hole. With this configuration, the first connector 12 and the second connector 202 can be connected simply by passing the locking member 30 through the inner connecting hole 121 and the outer connecting hole, and the first connector 12 and the second connector 202 can be separated simply by removing the locking member 30 from the inner connecting hole 121.

[0059] Please refer to Figure 1 , Figure 2 and Figure 3 In this embodiment, the forming frame 20 includes a fixing frame 21 and a forming frame 22 arranged along the first direction. The fixing frame 21 is connected to the base 10, and the fixing frame 21 can also be separated from the base 10.

[0060] The forming frame 20 also includes a plurality of adjusting members 23, which are spaced apart along the edge of the forming frame 22. Both the fixed frame 21 and the forming frame 22 are connected to the adjusting members 23. The adjusting members 23 are used to adjust the distance between the forming frame 22 and the fixed frame 21 in the first direction.

[0061] By adopting the above scheme, the distance between different parts of the forming frame 22 and the fixed frame 21 in the first direction can be adjusted using the adjusting member 23 as needed, thereby adjusting the forming angle of the flat glass.

[0062] Specifically, the molded part 201 includes a fixing frame 21 and a molding frame 22 disposed along a first direction. The fixing frame 21 is connected to the second connector 202.

[0063] It should be noted that the forming frame 22 is used to support the flat glass. When heated, the flat glass softens, and its center falls freely from the hollow part of the forming frame 20. The edges of the flat glass gradually conform to the forming frame 22, transforming the flat glass into a curved windshield. The shape of the flat glass can be controlled by adjusting the heating elements in the hot bending furnace, using zone switches, and controlling the heating temperature and time, thus making it a spherical or curved windshield.

[0064] Optionally, the adjusting element 23 may be a hydraulic cylinder, a pneumatic cylinder, or a linear module.

[0065] In this embodiment, the fixed frame 21 is provided with an adjusting threaded hole (not shown in the figure), the axis of which is parallel to the first direction; the adjusting member 23 passes through the adjusting threaded hole and is threadedly engaged with the fixed frame 21, and the adjusting member 23 is fixedly connected to the forming frame 22. This arrangement simplifies the structure of the adjusting member 23, thereby making it easier to adjust the distance between the forming frame 22 and the fixed frame 21 in the first direction.

[0066] Specifically, the forming frame 20 also includes multiple fastening nuts 24, which are correspondingly arranged with the adjusting member 23. The fastening nuts 24 are provided with fastening threaded holes, the axis of which is parallel to the first direction. The adjusting member 23 passes through the fastening threaded holes and is threadedly engaged with the fastening nuts 24, and the fastening nuts 24 abut against the fixed frame 21. This arrangement can prevent the adjusting member 23 from rotating freely after adjusting the distance between the forming frame 22 and the fixed frame 21 in the first direction by rotating the adjusting member 23 relative to the fixed frame 21.

[0067] Optionally, one adjusting member 23 is provided in correspondence with multiple adjusting members 23, and two of the adjusting members 23 corresponding to the same adjusting member 23 are located on opposite sides of the fixed frame 21. This arrangement can better prevent the adjusting members 23 from rotating freely.

[0068] The base of traditional hot bending forming molds is usually made of iron, which is heavy and difficult to move. In addition, it has low production efficiency and high energy consumption.

[0069] In this embodiment, the base 10 can be made of stainless steel (such as 304 stainless steel) square tubing, which is lighter and thinner, reducing the overall weight of the hot bending forming mold 100 by 40%, making it easier to move and install. It has high strength, and its specific heat capacity is much smaller than that of the original iron base. The specific heat capacity of iron is 0.467 kJ / (kg*°C), and the specific heat capacity of stainless steel is 0.5 kJ / (kg*°C). The base 10 in this embodiment absorbs less heat, which can play a role in energy saving and consumption reduction during its manufacturing process.

[0070] Please refer to Figures 7 to 12 In another embodiment, the first connector 12 is provided with a slot 122 at the end away from the support member 11, and the second connector 202 is detachably held in the slot 122 so as to realize the detachable connection between the first connector 12 and the second connector 202.

[0071] By adopting the above scheme, the structure of the hot bending forming mold 100 can be made simpler, and the base 10 and the forming frame 20 can be detachably connected. After the forming frame 20 is separated from the base 10, the overlapping part of the base 10 and the forming frame 20 in the first direction can be increased, thereby reducing the size of the hot bending forming mold 100 in the first direction, that is, reducing the space occupied by the hot bending forming mold 100 in the first direction, which is convenient for storage and transportation.

[0072] Specifically, the second connector 202 can be configured as a column.

[0073] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
