Description

Technical Field

[0001] This application relates to the field of glass accessory installation, and more particularly to a glass assembly, vehicle, and mold. Background Technology

[0002] Currently, the peripheral components of automotive window glass are generally fixedly connected to the glass through integrated injection molding to form a glass assembly. However, due to the matching precision of the injection mold, production defects such as burrs can easily occur at the edge of the molding during the injection molding process. These production defects usually need to be handled and repaired manually. However, manual trimming is inefficient and the degree of repair is random and cannot be standardized, so product stability is difficult to guarantee, and poor trimming can easily lead to the scrapping of the entire glass assembly. Summary of the Invention

[0003] The embodiments of this application provide a glass assembly, a vehicle, and a mold, which can improve the processing accuracy of the glass assembly, avoid flash in the glass assembly, and thus improve the production yield of the glass assembly.

[0004] In a first aspect, this application provides a glass assembly, comprising:

[0005] Glass body;

[0006] The injection-molded body is attached to the edge of the glass body;

[0007] The encapsulated part includes a connecting portion and a functional portion connected together. The connecting portion is embedded in the injection molded body, and the functional portion is exposed relative to the injection molded body. The functional portion includes a first abutting surface and a second abutting surface. In the thickness direction of the glass assembly, a portion of the first abutting surface and the second abutting surface are disposed opposite to each other. The first abutting surface is a curved surface. The first abutting surface is used to abut against a first mold. The second abutting surface is connected to the first abutting surface and is used to abut against a second mold. The connection between the second abutting surface and the first abutting surface is used to contact the second mold.

[0008] In this embodiment, since the first contact surface is a continuous curved surface, during the manufacturing process, the first contact surface and the first mold are aligned through the curved surface, and there are no sharp corners. If sharp corners exist, leakage points are easily generated with the mold surface during injection molding, causing the injection fluid to flow out from the leakage points and form flash.

[0009] Sharp corners are prone to friction and pressure with the mold, leading to scratches on the mold surface. Scratches not only affect the mold's precision and surface quality but can also cause defects in the injection-molded product. The absence of sharp corners on the encapsulated part significantly reduces the direct contact area and friction with the mold surface, thus lowering the risk of mold scratches. Reduced mold scratches mean the mold can remain in good condition for a longer period, extending its lifespan and preventing defects in the injection-molded body. Furthermore, the absence of sharp corners on the first contact surface of the encapsulated part helps maintain mold precision and surface quality, thereby improving the quality and appearance of the injection-molded body.

[0010] Furthermore, the curved surface of the first contact surface eliminates the sharp corners of the covered part, simplifying its structure and reducing its volume, thus achieving a lightweight design. Moreover, due to the simplified structure of the covered part, the corresponding mold structure can also be simplified, making mold processing easier and avoiding dead zones that are difficult for fluid to reach, thereby improving the molding integrity of the injection molded part.

[0011] In one possible implementation, one end of the first abutting surface and the second abutting surface intersects to form an intersection line, and the thickness of the functional part gradually increases from the intersection line in a direction away from the intersection line.

[0012] In this embodiment, the thickness at the intersection of the functional parts is relatively thin, and the intersection can be clamped by the first mold and the second mold. The intersection can be aligned with the parting line of the first mold and the second mold. The thickness of the functional parts can gradually increase in the direction away from the intersection line, thereby increasing the end face area of ​​the connection between the functional parts and the connecting parts, and increasing the structural stability of the covered part.

[0013] In one possible implementation, the glass assembly further includes a sealing protrusion, which protrudes from the first abutment surface and extends circumferentially along the outer edge of the first abutment surface. Both ends of the sealing protrusion extend to the intersection line in the length direction, and the sealing protrusion and the functional part are integrally formed.

[0014] In this embodiment, a sealing protrusion is used to seal the connection between the functional part and the first mold. When space is limited in some molds and a sealing body cannot be used, the sealing protrusion can be integrally molded with the functional part. During the glass assembly molding process, the end of the sealing protrusion contacts the second boss of the second mold, and the side of the sealing protrusion facing away from the first contact surface abuts against the first mold. The first mold can crush the sealing protrusion, thereby sealing any gaps that may exist between the functional part and the first and second molds, preventing leakage and flash from the injection molded body.

[0015] In one possible implementation, the functional part is provided with a first groove, which extends through the first abutting surface, the second abutting surface, and part of the intersection line in the thickness direction of the glass assembly. The sealing protrusion is arranged around the first groove and is located between the first groove and the connecting part.

[0016] In this embodiment, the first groove can provide a clearance position or a slot structure for other components of the vehicle, so that the glass assembly can be connected to the vehicle body structure.

[0017] In one possible implementation, the connecting portion further includes a first limiting body, which is connected to one end of the functional portion along its length. The first limiting body protrudes relative to the first abutting surface and is embedded in the injection molding body.

[0018] In this embodiment, the first limiting body can limit the covered part to the injection molded body, so that the connection between the covered part and the injection molded body is more secure, thereby improving the overall structural stability of the glass assembly.

[0019] In one possible implementation, the connecting portion is provided with a second groove, the second groove being recessed by the connecting portion toward the surface of the second mold, the second groove being disposed around the second abutment surface, the bottom wall of the second groove being recessed relative to the second abutment surface, and a portion of the injection molded body being located within the second groove.

[0020] In this embodiment, the second groove can increase the surface area of ​​the connection part in contact with the injection molded body, thereby increasing the bonding area between the connection part and the injection molded body, making the connection between the covered part and the injection molded body more stable and improving the overall structural stability of the glass assembly.

[0021] In one possible implementation, in the thickness direction of the glass assembly, at least a portion of the connecting portion is stacked and spaced apart from the glass body, and the functional portion protrudes relative to the edge of the glass body.

[0022] In this embodiment, the overlapping arrangement of the connecting portion and the edge of the glass body increases the bonding area by increasing the overlap between them. This allows the injection-molded body to be more evenly distributed between the two sheets, forming a more stable connection structure. A larger bonding area means more bonding points, thereby improving the overall strength of the glass assembly.

[0023] In one possible implementation, one end of the injection molded body is connected to the edge of the glass body, and the other end of the injection molded body opposite to it is provided with a receiving groove. In the thickness direction of the glass assembly, the receiving groove penetrates the injection molded body and penetrates the end face of the injection molded body opposite to the glass body. At least a portion of the functional part is located in the receiving groove.

[0024] Secondly, this application provides a vehicle, which includes a vehicle body and a glass assembly as described above, the glass assembly being connected to the vehicle body.

[0025] Thirdly, this application provides a mold for preparing the glass assembly as described above. The mold includes a first mold and a second mold, which are joined together to form a mold cavity for accommodating the glass body, the injection molded body, and the encapsulated part.

[0026] In one possible implementation, the first mold is further provided with a sealing body for sealingly connecting the first mold and the first abutting surface. The sealing body is used to extend circumferentially along the outer edge of the first abutting surface. The sealing body includes a first end and a second end disposed along the extension direction, and both the first end and the second end extend to the intersection of the first abutting surface and the second abutting surface.

[0027] In this embodiment, a sealing body is provided between the first mold and the first abutment surface of the functional part of the encapsulated component, allowing the first abutment surface to be sealed to the bottom wall of the clearance groove of the first mold. This prevents the injection fluid from passing through the gap between the first mold and the functional part of the encapsulated component, avoiding the formation of flash after the injection fluid leaks and solidifies. Flash is also prevented from affecting the appearance quality, dimensional accuracy, and function of the glass assembly.

[0028] In one possible implementation, the end face of both the first end and the end face of the second end are flush with the second abutment surface.

[0029] In this embodiment, the end face of the first end, the end face of the second end, and the second abutting surface can all abut against the surface of the second mold, thereby avoiding gaps between the second mold and the sealing body and preventing injection fluid from leaking between the second mold and the sealing body.

Detailed Implementation

[0045] For ease of understanding, the terminology used in the embodiments of this application will be explained first.

[0046] And / or: This is simply a way of describing the relationship between related objects. It indicates that there can be three kinds of relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0047] Multiple: refers to two or more.

[0048] Connection: should be interpreted broadly. For example, the connection between A and B can be a direct connection between A and B, or an indirect connection between A and B through an intermediary.

[0049] The specific embodiments of this application will now be clearly described in conjunction with the accompanying drawings.

[0050] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a vehicle 100 provided in an embodiment of this application. The vehicle 100 includes a vehicle body 10 and a glass assembly 20. The glass assembly 20 is connected to the vehicle body 10.

[0051] It should be noted that, Figure 1 The purpose is merely to illustratively describe the connection relationship between the vehicle body 10 and the glass assembly 20, and is not to specifically limit the connection positions, specific structures, or quantities of the various devices. Furthermore, the structures illustrated in the embodiments of this application do not constitute a specific limitation on the vehicle 100. In other embodiments of this application, the vehicle 100 includes... Figure 1This may involve more or fewer components, or combining certain components, or splitting certain components, or different component arrangements.

[0052] The integral injection-molded edging is fixedly connected to the glass to form a glass assembly. However, due to the matching precision of the injection mold, flash can easily form at the edge of the edging during the injection molding process. Especially when the covered part in the glass assembly has relatively sharp corners, gaps can easily appear between the corners and the mold during injection molding, which can easily lead to leakage of the injection fluid and the formation of flash.

[0053] Because the location of burrs is random and the burrs are relatively thin, they usually need to be processed and repaired manually. However, manual trimming depends on the trimmer's skill and cannot be standardized, making it difficult to guarantee product stability and easily leading to the scrapping of the entire product due to poor trimming. At the same time, manual trimming is slow and inefficient, and it is difficult to trim large glass products manually. Therefore, glass trimming can become a bottleneck process on the production line, requiring multiple trimmers to ensure process balance.

[0054] Based on this, this application provides a glass assembly 20 that can improve the processing accuracy of the glass assembly 20, avoid flash in the glass assembly 20, and thus improve the production yield of the glass assembly 20. The glass assembly 20 can be integrally injection molded in a mold.

[0055] For ease of description, please refer to Figure 2 , Figure 2 This is a schematic diagram of the structure of the mold 30 provided in the embodiment of this application.

[0056] The mold 30 includes a first mold 31 and a second mold 32. The first mold 31 and the second mold 32 can be assembled to form an injection cavity 33, which is used for integral injection molding of the glass assembly 20.

[0057] Please see Figure 3 , Figure 3 yes Figure 2 The diagram shows the structure of the first mold 31. The first mold 31 includes a first mold surface 311 and a second mold surface 312. The first mold surface 311 and the second mold surface 312 are arranged opposite to each other in the thickness direction of the first mold 31.

[0058] The first mold 31 is provided with a first groove 3111 and a second groove 3112. Both the first groove 3111 and the second groove 3112 are recessed from the first mold surface 311. The depth of the first groove 3111 can be greater than the depth of the second groove 3112.

[0059] The first mold 31 is provided with a first boss 3113, which protrudes from the bottom wall of the second groove 3112. The first boss 3113 is connected to the side wall of the second groove 3112 away from the first groove 3111. The surface of the first boss 3113 facing away from the bottom wall of the second groove 3112 is flush with the first mold surface 311. The first boss 3113 is recessed with a relief groove 3114, which is recessed from the edge of the surface of the first boss 3113 facing away from the second mold surface 312. The relief groove 3114 penetrates the peripheral side of the first boss 3113. The relief groove 3114 communicates with the second groove 3112. The bottom wall of the relief groove 3114 is a curved surface. In this embodiment, the curved surface can be regarded as the trajectory formed by a moving line (straight line or curve) moving continuously in space. It should be noted that a plane is also a special kind of curved surface.

[0060] Please see Figure 4 , Figure 4 yes Figure 2 The diagram shows the structure of the second mold 32. The second mold 32 includes a third mold surface 321 and a fourth mold surface 322. The third mold surface 321 and the fourth mold surface 322 are arranged opposite to each other in the thickness direction of the second mold 32. The second mold 32 is provided with a third groove 3211 and a second boss 3212. The third groove 3211 is recessed from the third mold surface 321. The second boss 3212 protrudes from the bottom wall of the third groove 3211. The second boss 3212 is connected to one side wall of the third groove 3211. The surface of the second boss 3212 facing away from the bottom wall of the third groove 3211 can be flush with the third mold surface 321.

[0061] Please refer to the following: Figure 2 , Figure 3 and Figure 4 After the first mold 31 and the second mold 32 are joined, the first mold surface 311 of the first mold 31 and the third mold surface 321 of the second mold 32 are connected. The first groove 3111 and the second groove 3112 are both opposite to the third groove 3211. The space between the first groove 3111 and the third groove 3211 is used to accommodate part of the glass body, part of the covered component, and part of the injection molded component. The space between the second groove 3112 and the third groove 3211 can be used to accommodate part of the covered component and part of the injection molded component.

[0062] The first boss 3113 of the first mold 31 is connected to the second boss 3212 of the second mold 32. The space between the clearance groove 3114 of the first boss 3113 and the second boss 3212 is used to accommodate the functional part of the covered component. The intersection line between the bottom wall of the clearance groove 3114 and the surface of the second boss 3212 is the parting line 34 of a part of the first mold 31 and the second mold 32.

[0063] Please see Figure 5 , Figure 5 yes Figure 1 The diagram shows a structural schematic of the glass assembly 20. The glass assembly 20 includes a glass body 21, an injection-molded body 22, and a covered component 23. The glass body 21 is injection-molded in a mold 30. The glass body 21 can be a side window, sunroof, or windshield of a vehicle 100, etc. This application does not limit the location of the glass body 21. The covered component 23 is fixed to the glass body 21 by the injection-molded body 22. The covered component 23 can be any accessory that needs to be connected to the glass body 21, such as a reinforcing member to enhance the overall strength of the glass assembly 20, a fixing slot, a buckle, or a pin for fixing the glass assembly 20 to the vehicle body 10, etc. The following example illustrates the covered component 23 as a slot structure.

[0064] The glass body 21 can be tempered glass. Tempered glass can be transparent low-iron glass (also known as ultra-clear glass), soda-lime glass, borosilicate glass, aluminosilicate glass, or K glass, etc. The glass body 21 can also be tempered glass. Tempering the glass body 21 increases its rigidity and reduces deformation. In practical use, this increased rigidity makes the glass body 21 less susceptible to damage from external forces, allowing it to adapt to a wider range of applications. The glass body 21 can also be semi-tempered glass. This type of glass body combines the high strength of tempered glass with the disadvantage of fully tempered glass, which is prone to shattering upon breakage. When a semi-tempered glass body 21 is broken, it can radially crack along the crack source, generally without tangential crack propagation, thus maintaining its integrity after breakage without collapsing.

[0065] The glass body 21 can also be laminated glass. Laminated glass is a composite glass product made by sandwiching one or more layers of organic polymer interlayer between two or more panes of glass, and then undergoing special high-temperature pre-pressing (or vacuuming) and high-temperature and high-pressure processes to permanently bond the glass and interlayer together. Laminated glass has good safety performance. It also has functions such as sound insulation and control of sunlight and ultraviolet rays.

[0066] The glass body 21 can also be any type of commonly used vehicle window glass. This application does not limit the specific structure of the glass body 21. The above description of the glass body 21 is merely illustrative.

[0067] Please see Figure 6 , Figure 6 This is a schematic diagram of the structure of the glass body 21 located inside the mold 30. During the preparation of the glass assembly 20, the glass body 21 can be located inside the first groove 3111, and the glass body 21 can be attached to the bottom wall of the first groove 3111, and has a gap with the side wall of the first groove 3111 near the second groove 3112.

[0068] Please refer to the following: Figure 7 and Figure 8 , Figure 7 yes Figure 5 The diagram shows a structural schematic of the covered component 23 at one angle. Figure 8 yes Figure 5 This is a structural schematic diagram of the covered component 23 from another angle. The covered component 23 includes a connecting portion 231 and a functional portion 232 connected together. The connecting portion 231 is used for fixed connection with the injection molded body 22. The functional portion 232 can be exposed relative to the injection molded body 22, so that it can be used for connection with other structural components, etc.

[0069] The connecting portion 231 includes a first segment 2311, a second segment 2312, and a third segment 2313. The first segment 2311 and the second segment 2312 are bent and connected to opposite sides of the third segment 2313, respectively. The first segment 2311 and the second segment 2312 extend in opposite directions.

[0070] The second segment 2312 includes a first surface 2314 and a second surface 2315. In the thickness direction of the glass assembly 20, the first surface 2314 and the second surface 2315 are arranged opposite to each other.

[0071] The second segment 2312 is provided with a second groove 2316 and a third groove 2317. The second groove 2316 is recessed from the second surface 2315 of the second segment 2312.

[0072] In the thickness direction of the glass assembly 20, the third groove 2317 penetrates the first surface 2314, the second surface 2315, and the end face of the second segment 2312 facing away from the third segment 2313. The third groove 2317 is surrounded by the second groove 2316.

[0073] Along the length of the covered part 23, the second section 2312 on both sides of the third groove 2317 forms a first limiting body 2318 and a second limiting body 2319. Both the first limiting body 2318 and the second limiting body 2319 can be embedded in the injection molded body 22.

[0074] The functional section 232 includes a first abutment surface 2321 and a second abutment surface 2322. The first abutment surface 2321 is curved, while the second abutment surface 2322 can be planar. In the thickness direction of the glass assembly 20, portions of the first abutment surface 2321 and the second abutment surface 2322 are disposed opposite to each other. Along the width direction of the functional section 232, the distance between the first abutment surface 2321 and the second abutment surface 2322 gradually decreases. The ends of the first abutment surface 2321 and the second abutment surface 2322 intersect, forming an intersection line 2323. The thickness of the functional section 232 gradually increases from the intersection line 2323 in a direction away from it.

[0075] In this embodiment, the thickness at the intersection line 2323 of the functional part 232 is relatively thin. The intersection line 2323 can be clamped by the first mold 31 and the second mold 32, and the intersection line 2323 can be aligned with the parting line 34 of the first mold 31 and the second mold 32. The thickness of the functional part 232 can gradually increase in the direction away from the intersection line 2323, thereby increasing the end face area of ​​the functional part 232 connected to the connecting part 231 and increasing the structural stability of the covered part 23.

[0076] The functional part 232 is also provided with a first groove 2324. In the thickness direction of the glass assembly 20, the first groove 2324 passes through the first abutment surface 2321, the second abutment surface 2322, and the intersection line 2323 of part of the first abutment surface 2321 and the second abutment surface 2322.

[0077] In this embodiment, the first groove 2324 can provide a clearance position or a slot structure for other components of the vehicle 100 so that the glass assembly 20 can be connected to the body 10 structure of the vehicle 100.

[0078] The side of functional part 232 facing away from the intersection line 2323 and the two end faces of functional part 232 facing away from each other along the length direction are connected to the groove wall of the third groove 2317 of the second segment 2312. The first abutting surface 2321 is provided on the same side as the first surface 2314 of the second segment 2312. The second abutting surface 2322 is provided on the same side as the second surface 2315. One end of the first abutting surface 2321 is smoothly connected to the second surface 2315. The other end of the first abutting surface 2321 extends towards the edge of the second abutting surface 2322. The first abutting surface 2321 is recessed relative to the first surface 2314, so that the first limiting body 2318 and the second limiting body 2319 located at both ends of the functional part 232 along the length direction protrude relative to the first abutting surface 2321. The second abutting surface 2322 can be flush with the second surface 2315. The three sides of the second abutting surface 2322 are surrounded by the second groove 2316. The bottom wall of the second groove 2316 is recessed relative to the second abutment surface 2322.

[0079] Please see Figure 9 , Figure 9 yes Figure 1The diagram shows a cross-sectional view of the glass assembly 20. During the fabrication of the glass assembly 20, the encapsulated part 23 can be located within the cavity of the mold 30 between the first mold 31 and the second mold 32. Specifically, the first segment 2311 of the connecting portion 231 of the encapsulated part 23 can be located within the third groove 3211 of the second mold 32, with the first segment 2311 spaced apart from the groove wall of the third groove 3211. The second segment 2312 of the connecting portion 231 is located within the second groove 3112 of the first mold 31. Part of the second segment 2312 is located between the first boss 3113 and the second boss 3212. Another portion of the second segment 2312 is located within the second groove 3112, spaced apart from both the groove wall of the second groove 3112 and the groove wall of the third groove 3211. A portion of the third segment 2313 of the connecting portion 231 is located within the first groove 3111, and a portion of the third segment 2313 is located within the third groove 3211 of the second mold 32. The first segment 2311 of the connecting part 231 is stacked and spaced apart from the glass body 21. The functional part 232, the first segment 2311, the second segment 2312 and the third segment 2313 of the connecting part 231 may protrude relative to the edge of the glass body 21.

[0080] In this embodiment, the overlapping arrangement of the connecting portion 231 and the glass body 21 at their edges increases the bonding area by increasing the overlap between them. This allows the injection-molded body 22 to be more evenly distributed between them, forming a more stable connection structure. A larger bonding area means more bonding points, thereby improving the overall strength of the glass assembly 20.

[0081] Please refer to the following: Figure 2 , Figure 7 and Figure 9 The functional part 232 of the covered part 23 is located between the first boss 3113 and the second boss 3212. The functional part 232 is embedded in the relief groove 3114 of the first boss 3113. The first abutting surface 2321 is used to abut against the first mold 31, and the second abutting surface 2322 is used to abut against the second mold 32. The intersection line 2323 of the first abutting surface 2321 and the second abutting surface 2322 can coincide with the parting line 34 of the mold 30.

[0082] The injection molded part 22 is used for injection molding in the cavity of the mold 30 formed by the joining of the first mold 31 and the second mold 32. Please refer to Figure 10 , Figure 10 yes Figure 1The diagram shows the structure of the injection-molded body 22 of the glass assembly 20. The injection-molded body 22 includes a third surface 221 and a fourth surface 222 arranged opposite to each other along the thickness direction, and a fifth surface 223 and a sixth surface 224 arranged opposite to each other along the width direction. It should be noted that in this embodiment, the thickness direction can be the same as the thickness direction of the glass body 21, and the length direction is also the direction extending along the edge of the glass body 21. The width direction can be perpendicular to the thickness direction and the length direction.

[0083] One end of the injection molded body 22 in the width direction is connected to the glass body 21. The other end of the injection molded body 22 in the width direction is used to expose the functional part 232 of the covered part 23.

[0084] The injection-molded body 22 may be provided with a first connecting groove 225, a second connecting groove 227, and a receiving groove 226. The first connecting groove 225 is recessed by a fifth surface 223 and penetrates through the third surface 221 of the injection-molded body 22. The first connecting groove 225 is connected to the edge of the glass body 21. The surface of the glass body 21 may be flush with the third surface 221. The receiving groove 226 is recessed by a sixth surface 224 and penetrates through the third surface 221 and the fourth surface 222 of the injection-molded body 22. That is, the receiving groove 226 penetrates through the glass assembly 20 along the thickness direction of the glass assembly 20. The second connecting groove 227 is located inside the injection-molded body 22 and communicates with the receiving groove 226.

[0085] Please refer to the following: Figure 5 , Figure 7 and Figure 10 The covered part 23 is connected within the second connecting groove 227. The first segment 2311, the second segment 2312, and the third segment 2313 of the connecting portion 231 of the covered part 23 are all covered by the injection molded body 22. The functional portion 232 of the covered part 23 is located within the receiving groove 226, thus protruding relative to the injection molded body 22. A portion of the injection molded body 22 is connected within the second groove 2316 of the second segment 2312. The injection molded body 22 covers the first limiting body 2318 and the second limiting body 2319 of the second segment 2312.

[0086] In this embodiment, the first limiting body 2318 and the second limiting body 2319 can limit the covered part 23 to the injection molded body 22, so that the connection between the covered part 23 and the injection molded body 22 is more secure, thereby improving the overall structural stability of the glass assembly 20.

[0087] Furthermore, the second groove 2316 increases the contact surface between the connecting part 231 and the injection molded body 22, thereby increasing the bonding area between the connecting part 231 and the injection molded body 22. This makes the connection between the covered part 23 and the injection molded body 22 more stable, improving the overall structural stability of the glass assembly 20. This prevents the glass assembly 20 from falling off or breaking due to poor structural strength during vehicle 100 use.

[0088] During the molding process of the glass assembly 20, the injection molded body 22 fills the first groove 3111, the second groove 3112 of the first mold 31, and the third groove 3211 of the second mold 32. After the injection molded body 22 solidifies, it connects the glass body 21 and the covered part 23 located in the mold 30.

[0089] In the first possible embodiment, please refer again. Figure 11 , Figure 11 yes Figure 1 A schematic diagram of another possible partial structure of the glass assembly 20 shown.

[0090] The mold 30 may also include a sealing body 40. The sealing body 40 may be a deformable flexible material such as an adhesive sealant. The sealing body 40 is connected to the first mold 31.

[0091] The sealing body 40 can be C-shaped. During the molding process of the glass assembly 20 in the mold 30, the sealing body 40 extends along the edge of the first abutment surface 2321 toward the connection portion 231, and the sealing body 40 is used to seal the first abutment surface 2321 to the first mold 31. The sealing body 40 can be arranged around the first groove 2324.

[0092] The sealing body 40 includes a first end and a second end disposed opposite to each other along the extending direction, both of which extend to the parting line 34. The end faces of both the first and second ends are flush with the second abutment surface 2322. The end face of the first end can fit against the surface of the second boss 3212 of the second mold 32. The end face of the second end can fit against the surface of the second boss 3212 of the second mold 32.

[0093] In this embodiment, since the first contact surface 2321 is a continuous curved surface, during the manufacturing process, the first contact surface 2321 and the first mold 31 are aligned through the curved surface, and there are no sharp corners. Sharp corners are prone to friction and extrusion with the surface of the mold 30 during injection molding, resulting in scratches on the surface of the mold 30. Scratches not only affect the precision and surface quality of the mold 30, but may also further lead to defects in the injection molded body 22. However, the covered part 23 has no sharp corners, which greatly reduces the direct contact area and friction with the surface of the mold 30, thereby reducing the risk of the mold 30 being scratched. Reducing scratches on the mold 30 means that the mold 30 can maintain a good condition for a longer time, thereby extending its service life. The precision and surface quality of the mold 30 directly affect the quality and appearance of the injection molded body 22. After the mold 30 is scratched, its surface quality decreases, which may lead to defects or flaws in the injection molded body 22. However, the covered part 23 has no sharp corners, which helps to maintain the precision and surface quality of the mold 30, thereby improving the quality and appearance of the injection molded body 22.

[0094] Furthermore, the curved surface of the first contact surface 2321 can eliminate the sharp corners of the covered part 23, thereby simplifying the structure of the covered part 23 and reducing its volume, achieving the goal of lightweight design. Moreover, due to the simplified structure of the covered part 23, some structures of the mold 30 corresponding to the covered part 23 can also be simplified, making mold 30 easier to process and avoiding dead corners in the mold 30 that are difficult for fluid to reach, thus improving the molding integrity of the injection molded body 22.

[0095] Furthermore, the end face of the first end, the end face of the second end, and the second abutment surface 2322 can all abut against the surface of the second mold 32, thereby preventing gaps from appearing between the second mold 32 and the sealing body 40, and preventing the injection fluid from leaking between the second mold 32 and the sealing body 40.

[0096] Please refer to the following: Figure 2 and Figure 11 In this embodiment, during the fabrication of the glass assembly 20, the sealing body 40 allows the first contact surface 2321 to be sealed to the bottom wall of the clearance groove 3114 of the first mold 31. This prevents the injection molding fluid from passing through the gap between the first mold 31 and the functional part 232 of the covered component 23. It also prevents the formation of flash after the injection molding fluid solidifies, thus avoiding flash affecting the appearance quality, dimensional accuracy, and function of the glass assembly 20.

[0097] For the second possible implementation, please refer to [the relevant documentation]. Figure 12 and Figure 13 , Figure 12 yes Figure 1 A schematic diagram of another possible partial structure of the glass assembly 20 shown. Figure 13 yes Figure 12 The diagram shows a cross-sectional view of the glass assembly 20 at point AA. Unlike the first possible embodiment, the covered component 23 in this embodiment is provided with a sealing protrusion 60.

[0098] During the fabrication of the glass assembly 20, a sealing protrusion 60 is formed on the first abutment surface 2321. The sealing protrusion 60 is located between the first groove 2324 and the connecting portion 231. The sealing protrusion 60 extends along the first abutment surface 2321 toward the edge of the connecting portion 231. Please refer to the reference section. Figure 2 and Figure 12 The sealing protrusion 60 extends to the parting line 34 at both ends along its length. Both end faces of the sealing protrusion 60 along its length are used to abut against the second mold 32. The side of the sealing protrusion 60 facing away from the first abutment surface 2321 is used to abut against the first mold 31. The height D1 of the sealing body 40 can be greater than or equal to 0.05 mm. The width D2 of the sealing protrusion 60 can be greater than or equal to 0.1 mm.

[0099] In this embodiment, a sealing body may not be required, and a sealing protrusion 60 can be used to seal the connection between the functional part 232 and the first mold 31. In cases where space is limited in some molds 30 and a sealing body cannot be used, the sealing protrusion 60 can be integrally formed with the functional part 232. During the molding process of the glass assembly 20, the end of the sealing protrusion 60 contacts the second boss 3212 of the second mold 32, and the side of the sealing protrusion 60 facing away from the first abutment surface 2321 abuts against the first mold 31. The first mold 31 can crush the sealing protrusion 60, thereby sealing any gaps that may exist between the functional part 232 and the first and second molds 31, preventing leakage and flash from the injection molded body 22.

[0100] In practical use, when the height of the sealing protrusion 60 is less than 0.05 mm, it is usually unable to completely fill the gap between the first mold 31 and the first abutment surface 2321 after being crushed. When the width of the sealing protrusion 60 is less than 0.1 mm, the connection between the sealing protrusion 60 and the first abutment surface 2321 is unstable after being crushed, causing the sealing protrusion 60 to detach from the gap between the first abutment surface 2321 and the first mold 31, thus affecting the sealing effect. Therefore, this application sets the height of the sealing protrusion 60 to be greater than or equal to 0.05 mm and the width of the sealing protrusion 60 to be greater than or equal to 0.1 mm.

[0101] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
