Description

Technical Field

[0001] This utility model relates to the field of glass injection molding technology, and in particular to a glass edging production device. Background Technology

[0002] Currently, traditional circular vacuum suction cups are used in the glass injection molding process for PVC (polyvinyl chloride) edge-wrapping molds, with different sized suction cups applied for different glass sizes. However, when injection molding smaller glass areas, such as automotive corner window glass, the smaller glass size, the requirement for sufficiently uniform suction, and the limited internal space of the mold limit the size of the suction cups that can be selected. This results in insufficient suction to provide adequate force to the glass, causing glass displacement during the injection molding process and affecting the product yield. Utility Model Content

[0028] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0029] Please refer to Figure 1 and Figure 2A glass edging production device includes a suction cup body 1, which has an adsorption surface 11 and an air extraction port 12. The adsorption surface 11 is triangular in shape. The air extraction port 12 is used to connect to an external negative pressure air source.

[0030] As can be seen from the above description, the beneficial effects of this utility model are as follows: the suction cup body 1 is provided with an adsorption surface 11 and an air extraction port 12. The shape and size of the adsorption surface 11 are similar to those of the glass product 2, so as to achieve the conformal function of adapting to the glass product 2. While ensuring that the adsorption surface 11 does not exceed the edge of the glass product 2, the adsorption area is maximized to enhance the adsorption effect on the glass, prevent it from shifting during the injection molding process, and improve the product yield.

[0031] Furthermore, it also includes a suction cup base 3; the suction cup base 3 is provided with a first suction pipe 4; the suction cup body 1 is located on the suction cup base 3, one end of the first suction pipe 4 is connected to the suction port 12, and the other end of the first suction pipe 4 is used to connect to an external negative pressure air source.

[0032] As can be seen from the above description, the suction cup base 3 provides a stable support foundation for the suction cup body 1, ensuring that the suction cup body 1 can withstand a certain weight and external force in the suction state, and ensuring that the equipment or object connected to it will not fall off or shake due to gravity or other external forces; at the same time, the first air extraction pipe 4 is provided to facilitate the connection of the air extraction interface 12 to an external negative pressure air source.

[0033] Furthermore, it also includes a support base 5; the support base 5 is provided with a limiting groove 6 adapted to the suction cup base 3; the suction cup base 3 is located in the limiting groove 6.

[0034] As can be seen from the above description, a support base 5 is provided to facilitate the placement of the entire contour suction cup on the edge-wrapping mold operation site; a limiting groove 6 is provided on the support base 5 to prevent the contour suction cup from shifting position.

[0035] Furthermore, the cross-sectional shape of the support base 5 is the same as that of the adsorption surface 11, and the area of ​​the cross-section is larger than that of the adsorption surface 11.

[0036] As can be seen from the above description, not only does the suction cup body 1 adopt a contour-following design, but the support base 5 also adopts a corresponding contour-following design. While providing a support base, the space occupied by the support base 5 at the work site can only fall within the range that the front projection of the glass product can cover. Compared with some support structures that exceed the range that the front projection of the glass product can cover, it can save the space occupied by the device at the work site.

[0037] Furthermore, the support base 5 is provided with a second air extraction pipe 7; one end of the second air extraction pipe 7 is connected to the end of the first air extraction pipe 4 away from the air extraction interface 12, and the other end of the second air extraction pipe 7 is used to connect to an external negative pressure air source.

[0038] As can be seen from the above description, the support base 5 has a built-in second air extraction pipe 7; the second air extraction pipe 7 works in conjunction with the first air extraction pipe 4 to connect the external negative pressure air source and the air extraction interface 12; the built-in air circuit design structure is stable and not easily affected by external interference.

[0039] Furthermore, a sealing ring 8 is provided at the connection between the first air extraction pipe 4 and the second air extraction pipe 7.

[0040] As can be seen from the above description, a sealing ring 8 is set between the first suction pipe 4 and the second suction pipe 7 to improve the airtightness of the connection, so as to prevent gas from leaking into the pipe and affecting the suction effect, and to ensure that the suction cup body 1 on the glass product 2 remains in a vacuum adsorption state after suction.

[0041] Furthermore, the shape and size of the support surface of the suction cup base 3 are the same as those of the suction surface 11.

[0042] As can be seen from the above description, the shape and size of the support surface of the suction cup base 3 are the same as those of the adsorption surface 11, so as to form a rigid support for the entire adsorption surface 11, ensuring that it is in close contact with the glass product 2 and enhancing the adsorption effect.

[0043] Furthermore, the suction surface 11 of the suction cup body 1 is provided with a groove 13; the groove 13 is connected to the air extraction port 12.

[0044] As can be seen from the above description, the groove 13 effectively increases the vacuum area of ​​the adsorption surface 11 at the air extraction port, strengthens the adsorption effect of the suction cup body 1, and prevents the glass product 2 from shifting during the injection molding process.

[0045] Furthermore, the number of grooves 13 is at least two.

[0046] As can be seen from the above description, multiple grooves 13 are provided on the adsorption surface 11 to form a strong adsorption at multiple points, thereby enhancing the adsorption effect.

[0047] Furthermore, the suction cup body 1 is provided with a soft material layer 14, and the adsorption surface 11 is located on the soft material layer 14.

[0048] As can be seen from the above description, using the surface of the soft material layer 14 on the suction cup body 1 as the adsorption surface 11 can ensure that the adsorption surface 11 is in close contact with the surface of the glass product 2, thus ensuring the adsorption effect.

[0049] Furthermore, the flexible material layer 14 can be natural rubber, nitrile rubber, or polyvinyl chloride.

[0050] As can be seen from the above description, the rubber layer has good elasticity and flexibility, and can closely adhere to the glass surface to form a sealed space, thereby generating an adsorption force.

[0051] Please refer to Figure 1 and Figure 2 Embodiment 1 of this utility model is as follows:

[0052] A glass edging production device includes a suction cup body 1, which has an adsorption surface 11 and an air extraction port 12. The adsorption surface 11 is triangular in shape. The air extraction port 12 is used to connect to an external negative pressure air source.

[0053] In this embodiment, the shape of the adsorption surface 11 of the suction cup body 1 is the same as that of the glass product 2, and the size of the adsorption surface 11 is smaller than that of the glass product 2, such as... Figure 1 As shown, glass product 2 is a triangular corner window glass, so the adsorption surface 11 is designed as a triangle.

[0054] Furthermore, to enhance the adsorption effect, a groove 13 is provided on the adsorption surface 11 of the suction cup body 1; the groove 13 is connected to the air extraction port 12. In use, the adsorption surface 11 of the suction cup body 1 is in contact with the surface of the glass product 2; an external negative pressure air source, such as a vacuum pump, extracts the air between the adsorption surface 11 and the surface of the glass product 2, forming a vacuum space in the groove 13.

[0055] The number of grooves 13 is at least two. Specifically, as follows: Figure 1 As shown, a large groove 13 and four small grooves 13 are provided; on the adsorption surface 11, the four small grooves 13 are arranged around the large groove 13. In other equivalent embodiments, the number of grooves 13, the size of the grooves 13, and their distribution positions can be designed according to the actual shape of the adsorption surface 11.

[0056] In addition, the suction cup body 1 is provided with a soft material layer 14, and the adsorption surface 11 is located on the soft material layer 14. The soft material layer 14 can be made of soft materials such as natural rubber, nitrile rubber, and polyvinyl chloride.

[0057] Please refer to Figure 2 Embodiment two of this utility model is as follows:

[0058] A glass edging production device, based on the above embodiment 1, further includes a suction cup base 3; the suction cup base 3 is provided with a first air extraction pipe 4; the suction cup body 1 is located on the suction cup base 3, one end of the first air extraction pipe 4 is connected to the air extraction interface 12, and the other end of the first air extraction pipe 4 is used to connect to an external negative pressure air source.

[0059] In this embodiment, as Figure 2 As shown, the suction cup base 3 is also provided with a relief groove for the fitting groove 13, so that the bottom of the entire suction cup body 1 is partially embedded in the suction cup base 3, while the soft material layer 14 on the top of the suction cup body 1 is located on the surface of the base.

[0060] Furthermore, the shape and size of the support surface of the suction cup base 3 are the same as those of the adsorption surface 11. For example, if the adsorption surface 11 is designed as a triangle, then the support surface of the suction cup base 3 is also a triangle, providing full support for the adsorption surface 11.

[0061] Please refer to Figure 2 Embodiment three of this utility model is as follows:

[0062] A glass edging production apparatus, based on the above-described embodiment two, further includes a support base 5; the support base 5 is provided with a limiting groove 6 adapted to a suction cup base 3; the suction cup base 3 is located within the limiting groove 6. The cross-sectional shape of the support base 5 is the same as that of the adsorption surface 11, and the area of ​​the cross-section is larger than that of the adsorption surface 11.

[0063] like Figure 2 As shown, the support base 5 provides height support for the suction cup base 3 and the suction cup body 1, enabling the suction cup body 1 to contact the glass product 2. Simultaneously, the support base 5 contains a second suction pipe 7; one end of the second suction pipe 7 is connected to the end of the first suction pipe 4 furthest from the suction port 12, and the other end of the second suction pipe 7 is used to connect to an external negative pressure air source.

[0064] In this embodiment, the upper end of the second suction pipe 7 passes through the top of the support base 5 and is located in the limiting groove 6, thereby connecting with the first suction pipe 4 of the suction cup base 3 in the limiting groove 6. In order to improve air tightness, a sealing ring 8 is provided at the connection between the first suction pipe 4 and the second suction pipe 7.

[0065] In summary, the glass edging production device provided by this utility model has an adsorption surface and an air extraction port on the suction cup body. The adsorption surface is triangular in shape to achieve a conformal effect to the glass product. While ensuring that the adsorption surface does not exceed the edge of the glass product, the adsorption area is maximized to enhance the adsorption effect on the glass, prevent displacement during injection molding, and improve the product yield. At the bottom of the suction cup body, there is a suction cup base with the same conformal design and a support base mounted on the suction cup base to provide rigid support for the suction cup body. An air extraction pipe is set inside the suction cup base and the support base, which connects the air extraction port to an external negative pressure air source to improve the stability of the air circuit connection. A sealing ring is set on the basis of the internal air circuit to ensure the adsorption effect.

[0066] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
