Overmolding mold for a glass assembly

Abstract

This invention provides a edging injection mold for a glass assembly, comprising a mold body and an adaptive elastic structure. The mold body includes a detachably disposed upper mold and a lower mold, which, when closed, form a first edging injection chamber surrounding at least a portion of the glass assembly. The adaptive elastic structure is disposed on the upper mold and / or the lower mold, and has an elastic break-resistant surface facing the glass assembly, which can float and abut against the glass assembly. This invention, through its adaptive elastic structure, forms an elastic break-resistant surface facing the glass assembly, which can float and abut against the glass assembly. This allows the injection mold to better adapt to fluctuations in the glass surface, avoiding rigid contact between the upper and lower molds after mold closing, thus preventing damage to the glass assembly. This reduces the risk of glass assembly damage, increases the edging yield, and ultimately improves product quality.

Description

Technical Field

[0001] This invention relates to the field of mold technology, and in particular to an edge-wrapping injection mold for glass assemblies. Background Technology

[0002] Glass edging assemblies are used in vehicles such as automobiles, passenger cars, buses, and taxis. These assemblies are typically manufactured using integral injection molding, which helps to accelerate manufacturing efficiency and improve the quality of the glass edging assembly. In this field, guide rails, glass, and iron parts with a high-gloss black surface are placed together in a mold. Molten plastic is then injected into the mold using an injection molding machine. After the injection material cools, it connects the glass, guide rails, and iron parts together. The glass edging assembly can then be removed after the mold is opened. Glass is a fragile and brittle material, especially laminated glass, which has lower strength and is more prone to cracking. Due to the instability of glass, high requirements are placed on the structure and precision of the molds used for edging injection molding.

[0003] The thickness tolerance of general glass is only ±0.2mm at most, and the surface variability is only ±0.75mm. Injection molds are typically designed to rigidly contact the glass rim with the upper and lower mold cores to ensure proper sealing, with a sealing width generally ranging from 7mm to 25mm. If the glass thickness and surface tolerances cannot be guaranteed, the glass is easily crushed during injection molding or may crack under stress. This not only affects product yield and production efficiency but also causes the broken glass to scratch the mold surface. Therefore, how to make injection molds better adapt to glass surface variability to improve product quality has become a pressing technical problem. Summary of the Invention

[0058] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] Please refer to the following: Figures 1 to 11As shown, an embodiment of the present invention provides an edge-wrapping injection mold for a glass assembly. The edge-wrapping injection mold for a glass assembly includes a mold body 100 and an adaptive elastic structure 200. The mold body 100 includes a detachably disposed upper mold 110 and a lower mold 120. After the upper mold 110 and the lower mold 120 are closed, a first edge-wrapping injection chamber 130 is formed surrounding at least a portion of the glass assembly 10. The adaptive elastic structure 200 is disposed on the upper mold 110 and / or the lower mold 120. The adaptive elastic structure 200 has an elastic abutment surface 20 facing the glass assembly 10. The elastic abutment surface 20 can float and abut against the glass assembly 10.

[0060] Overall, when using this edge-wrapping injection mold for glass assemblies, the glass assembly 10 to be edge-wrapped is placed at the target station of the lower mold 120, and the attachments on the glass assembly 10 can be simultaneously placed on the lower mold 120. Then, the upper mold 110 and the lower mold 120 are closed, thereby forming a first edge-wrapping injection chamber 130 surrounding at least a portion of the glass assembly 10 through the cooperation of the upper mold 110 and the lower mold 120. By injecting the molten material into the first edge-wrapping injection chamber 130, an edge-wrapping structure can be formed on the glass assembly 10 through a single injection molding process, and the attachments are simultaneously injection-molded and fixed in the glass assembly 10, significantly improving the processing efficiency of the edge-wrapping 30.

[0061] Furthermore, an adaptive elastic structure 200 is provided on the upper mold 110 and / or the lower mold 120. The adaptive elastic structure 200 can form an elastic break-resistant surface 20 facing the glass assembly 10. The elastic break-resistant surface 20 can float and abut against the glass assembly 10, thereby playing an adaptive adjustment role according to the shape of the glass assembly 10. This allows the injection mold of the present invention to better adapt to the fluctuation of the glass surface, avoids the upper mold 110 and the lower mold 120 rigidly abutting against the glass assembly 10 after mold closing, which would cause damage to the glass assembly 10, reduces the risk of damage to the glass assembly 10, improves the yield of the edge banding 30, and thus improves product quality.

[0062] In embodiments of the present invention, designers may adjust the specific structure of the glass assembly 10 according to usage needs. For example, the glass assembly 10 may include, but is not limited to, single-pane glass or laminated glass, without specific limitations.

[0063] In one feasible embodiment of the present invention, such as Figure 1 and Figure 6 In the embodiment shown, the upper mold 110 includes an upper positioning portion 140 that protrudes towards the glass assembly 10. The upper positioning portion 140 has a rigid abutment surface facing the glass assembly 10, and the rigid abutment surface can abut against the glass assembly 10.

[0064] By providing an upper positioning part 140 on the upper mold 110, the rigid contact surface of the upper positioning part 140 can abut against the glass assembly 10, thereby providing a more stable fixation for the glass assembly 10 and preventing the glass assembly 10 from shifting during the edge-wrapping 30 injection molding process.

[0065] Designers can adjust the specific shape and size of the upper positioning part 140 according to usage needs, and no specific restrictions are imposed here. Preferably, the cross-section of the upper positioning part 140 is approximately rectangular.

[0066] Furthermore, along the circumference of the glass assembly 10, such as Figure 7 In the embodiment shown, the upper positioning part 140 can be arranged in a gradient, so that the upper positioning part 140 has different radial dimensions, thereby adjusting the size and coverage of the first edge-sealing injection cavity 130 according to a preset target, so as to better meet the needs of the edge-sealing 30.

[0067] Furthermore, along the circumference of the glass assembly 10, the upper positioning part 140 may be continuously arranged, or the upper positioning part 140 may be composed of multiple upper positioning blocks spliced ​​together, without specific limitations here.

[0068] In embodiments of the present invention, such as Figure 2 In the embodiment shown, the adaptive elastic structure 200 includes at least one upper elastic block 210 disposed on the upper mold 110. The upper elastic block 210 is disposed inside the upper positioning part 140, and an elastic breaking surface 20 is formed on the upper elastic block 210.

[0069] By setting an upper elastic block 210 on the upper mold 110, the elastic breaking surface 20 of the upper elastic block 210 can float against the upper end surface of the glass assembly 10, thereby playing a floating adjustment role. This facilitates the absorption of the thickness and surface fluctuation tolerances of the glass assembly 10, allowing the upper mold 110 to better fit the upper end surface of the glass assembly 10, which helps to reduce the risk of the glass assembly 10 breaking.

[0070] Designers can adjust the specific shape and size of the upper elastic block 210 according to usage needs, and no specific restrictions are imposed here. Preferably, the cross-section of the upper elastic block 210 is approximately rectangular.

[0071] Furthermore, along the circumference of the glass assembly 10, the upper elastic block 210 can be arranged in a gradually varying manner, so that the elastic contact surface 20 of the upper elastic block 210 has different radial dimensions, thereby being able to better abut against different positions on the upper end surface of the glass assembly 10.

[0072] Furthermore, along the circumference of the glass assembly 10, the upper elastic block 210 may be continuously arranged, or the upper elastic block 210 may be composed of multiple elastic blocks spliced ​​together, without specific limitations here.

[0073] The amount of interference between the elastic surface 20 of the upper elastic block 210 and the glass assembly 10 can be adjusted by adjusting the gap between the upper mold 110 and the lower mold 120 or by replacing the upper elastic block 210 with one of different thicknesses. Furthermore, the elastic material used in the upper elastic block 210 does not adhere to the edge 30, thus facilitating demolding.

[0074] In another feasible embodiment of the invention, such as Figure 3 and Figure 9 In the embodiment shown, the upper mold 110 further includes an upper positioning portion 140 protruding towards the glass assembly 10, and a first decorative body 141 disposed on the upper positioning portion 140. At least a portion of the first decorative body 141 protrudes into the first edge-sealing injection cavity 130. The first decorative body 141 has a rigid break-resistant surface and / or an elastic break-resistant surface 20 facing the glass assembly 10.

[0075] By setting the first trimming body 141 on the upper positioning part 140 and at least a portion of the first trimming body 141 protruding in the first edge-sealing injection cavity 130, the edge of the edge-sealing 30 located on the upper end surface of the glass assembly 10 can be recessed into the edge-sealing 30 body, preventing the edge of the edge-sealing 30 from being exposed, thereby improving the aesthetics of the edge of the edge-sealing 30, and also serving to eliminate the need for trimming burrs and applying the base coat.

[0076] In one specific embodiment, the first decorative body 141 includes a first decorative elastic block. Specifically, the first decorative elastic block is fitted onto the upper positioning portion 140, and one end of the first decorative elastic block near the first edge-sealing injection chamber 130 protrudes into the first edge-sealing injection chamber 130, so that a concave structure is formed between the edge-sealing 30 and the upper end surface of the glass assembly 10, thereby eliminating the problem of flash.

[0077] In another specific embodiment, the first trimming body 141 includes a first mold slider. Specifically, the first mold slider is fitted onto the upper positioning part 140, and one end of the first mold slider near the first edge-sealing injection chamber 130 protrudes into the first edge-sealing injection chamber 130, so that a concave structure is formed between the edge-sealing 30 and the upper end face of the glass assembly 10, thereby eliminating the problem of flash.

[0078] Furthermore, in order to avoid abrupt changes in shape affecting the edge quality of the edging 30, the first decorative elastic block or the first mold slider is provided with a chamfer, so that the end of the first decorative elastic block or the first mold slider and the upper positioning part 140 are smoothly transitioned, without specific limitations here.

[0079] Designers can adjust the specific shape and structure of the first decorative elastic block or the first mold slider according to the needs of use, and no specific limitations are imposed here. Preferably, the first decorative elastic block or the first mold slider is constructed as a plate.

[0080] In embodiments of the present invention, such as Figure 1 In an embodiment, the adaptive elastic structure 200 includes a first lower elastic block 220 disposed on the lower mold 120, and an elastic break-resistant surface 20 facing the glass assembly 10 is formed on the first lower elastic block 220.

[0081] By setting a first lower elastic block 220 on the lower mold 120, the elastic breaking surface 20 of the first lower elastic block 220 can float against the lower end surface of the glass assembly 10, thereby playing a floating adjustment role. This facilitates the absorption of the thickness and surface fluctuation tolerances of the glass assembly 10, allowing the lower mold 120 to better fit the lower end surface of the glass assembly 10, which helps to reduce the risk of the glass assembly 10 breaking under pressure.

[0082] Designers can adjust the specific shape and size of the first lower elastic block 220 according to usage needs, without making specific limitations here. Preferably, the cross-section of the first lower elastic block 220 is approximately rectangular.

[0083] Furthermore, along the circumference of the glass assembly 10, the first lower elastic block 220 can be arranged in a gradually varying manner, so that the elastic abutment surface 20 on the first lower elastic block 220 has different radial dimensions, thereby being able to better abut against different positions on the lower end surface of the glass assembly 10.

[0084] Furthermore, along the circumference of the glass assembly 10, the first lower elastic block 220 can be continuously arranged, or the first lower elastic block 220 can be composed of multiple lower elastic blocks spliced ​​together, without specific limitations. The elastic material used for the first lower elastic block 220 does not adhere to the edge 30, thus facilitating demolding.

[0085] In embodiments of the present invention, such as Figure 2 , Figure 3 and Figure 4 In the embodiment shown, the adaptive elastic structure 200 further includes a second lower elastic block 230 disposed on the lower mold 120. The second lower elastic block 230 is spaced apart inside the first lower elastic block 220. An elastic breaking surface 20 facing the glass assembly 10 is formed on the second lower elastic block 230. The gap between the second lower elastic block 230 and the first lower elastic block 220 forms a second edge-sealing injection cavity 150.

[0086] By spaced apart from the first lower elastic block 220, a second edge-sealing injection molding chamber 150 can be formed. The second edge-sealing injection molding chamber 150 can be used to form an edge-sealing structure on the lower end surface of the glass assembly 10, thereby better meeting the setting requirements of the edge-sealing 30 on the glass assembly 10.

[0087] Furthermore, by setting a second lower elastic block 230, the first lower elastic block 220 and the second lower elastic block 230 can cooperate to form a larger area of ​​elastic support surface 20, thereby providing better support for the glass assembly 10. The specific arrangement of the second lower elastic block 230 can be referred to that of the first lower elastic block 220, and will not be repeated here.

[0088] In embodiments of the present invention, such as Figure 3 In the embodiment shown, a second decorative body 221 is provided on the first lower elastic block 220, and at least a portion of the second decorative body 221 protrudes from the first edge-sealing injection chamber 130 and / or the second edge-sealing injection chamber 150; and / or, a third decorative body 231 is provided on the second lower elastic block 230, and at least a portion of the second decorative body 221 protrudes from the second edge-sealing injection chamber 150.

[0089] Preferably, at least a portion of the second decorative element 221 protrudes from the first edge-sealing injection chamber 130 and the second edge-sealing injection chamber 150, respectively. Furthermore, the second lower elastic block 230 is provided with a third decorative element 231, and at least a portion of the second decorative element 221 protrudes from the second edge-sealing injection chamber 150.

[0090] By setting the second trimming body 221 on the first lower elastic block 220 and at least a portion of the second trimming body 221 protruding in the first edge-sealing injection cavity 130, the edge of the edge-sealing 30 located on the lower end surface of the glass assembly 10 can be recessed into the edge-sealing 30 body, preventing the edge of the edge-sealing 30 from being exposed, thereby improving the aesthetics of the edge of the edge-sealing 30, and also serving to eliminate the need for trimming burrs and applying the base coat.

[0091] Furthermore, at least a portion of the second trim body 221 protrudes into the second edge-sealing injection cavity 150, thereby allowing the edge of the edge-sealing 30 located on the lower end face of the glass assembly 10 to be recessed into the edge-sealing body, preventing the edge of the edge-sealing 30 from being exposed, thus improving the aesthetics of the edge of the edge-sealing 30, and also serving to eliminate the need for trimming burrs and applying the base coat.

[0092] Similarly, by setting the third trimming body 231 on the second lower elastic block 230 and at least a portion of the third trimming body 231 protruding in the second edge-sealing injection cavity 150, the edge of the edge-sealing 30 located on the lower end surface of the glass assembly 10 can be recessed into the edge-sealing body, preventing the edge of the edge-sealing 30 from being exposed, thereby improving the aesthetics of the edge of the edge-sealing 30.

[0093] In one specific embodiment, such as Figure 3In the embodiment shown, the second modification body 221 includes two second modification elastic blocks, which are respectively disposed on the two side walls of the first lower elastic block 220 and protrude from the first edge-sealing injection chamber 130 and the second edge-sealing injection chamber 150.

[0094] The second decorative elastic block is externally connected to the side wall of the first lower elastic block 220, or the second decorative elastic block and the first lower elastic block 220 are integrally formed, without specific limitations.

[0095] Furthermore, such as Figure 3 In the embodiment shown, the third trimming body 231 includes a third trimming elastic block, which is disposed on the side wall of the second lower elastic block 230 and protrudes into the second edge-sealing injection molding chamber 150.

[0096] The third decorative elastic block is externally connected to the side wall of the second lower elastic block 230, or the third decorative elastic block and the second lower elastic block 230 are integrally formed, without specific restrictions.

[0097] Of course, in other feasible embodiments, designers may adjust the specific settings of the second modifier 221 and the third modifier 231 according to the needs of use, and no specific restrictions are imposed here.

[0098] In embodiments of the present invention, such as Figure 3 and Figure 4 In the embodiment shown, the projection of the upper positioning part 140 is located within the projection range of the first lower elastic block 220 along the height direction.

[0099] By positioning the projection of the upper positioning part 140 within the projection range of the first lower elastic block 220, the first lower elastic block 220 has a larger supporting area than the upper positioning part 140, thus avoiding the shearing force generated by the staggered arrangement between the upper positioning part 140 and the first lower elastic block 220, thereby reducing the risk of the glass assembly 10 breaking.

[0100] Designers can adjust the projected area of ​​the upper positioning part 140 and the projected area of ​​the first lower elastic block 220 according to the needs of use, without making specific restrictions here.

[0101] In embodiments of the present invention, such as Figure 5 In the embodiment shown, the glass assembly 10 is provided with a guide rail 11, and the mold body 100 also includes a first abutting part 111 provided on the upper mold 110 and a second abutting part 121 provided on the lower mold 120. After the upper mold 110 and the lower mold 120 are closed, the first abutting part 111 and the second abutting part 121 abut against the two sides of the guide rail 11 respectively.

[0102] The first abutting part 111 provided on the upper mold 110 and the second abutting part 121 provided on the lower mold 120 can cooperate to abut against both sides of the guide rail 11, thereby limiting the guide rail 11 and enabling the guide rail 11 to cooperate with the glass assembly 10 according to the preset position.

[0103] Furthermore, after the upper mold 110 and the lower mold 120 are closed, at least a portion of the first edge-sealing injection cavity 130 can be formed between the guide rail 11, the glass assembly 10, the upper mold 110 and the lower mold 120. By injection molding the first edge-sealing injection cavity 130, a partial edge-sealing 30 can be formed between the guide rail 11 and the glass assembly 10 to fix the guide rail 11 and the glass assembly 10 together.

[0104] In embodiments of the present invention, such as Figure 5 In the embodiment shown, the upper mold 110 is further provided with a fourth decorative body 112, at least a portion of which protrudes from the gap between the glass assembly 10 and the guide rail 11; and / or, the lower mold 120 is further provided with a fifth decorative body 122, at least a portion of which protrudes from the gap between the glass assembly 10 and the guide rail 11.

[0105] Preferably, the upper mold 110 is further provided with a fourth decorative body 112, at least a portion of which protrudes from the gap between the glass assembly 10 and the guide rail 11; and the lower mold 120 is further provided with a fifth decorative body 122, at least a portion of which protrudes from the gap between the glass assembly 10 and the guide rail 11.

[0106] By providing a fourth trimming body 112 and having at least a portion of the fourth trimming body 112 protrude into the gap between the glass assembly 10 and the guide rail 11, after injection molding in the first edge-sealing injection chamber 130, the edge of the edge-sealing 30 located between the end of the guide rail 11 and the upper end face of the glass assembly 10 can also be recessed into the guide rail 11, thereby preventing the edge of the edge-sealing 30 from being exposed, thus improving the aesthetics of the edge of the edge-sealing 30, and also serving to eliminate the need for trimming burrs and applying a base coat.

[0107] Similarly, by providing a fifth decorative element 122 and having at least a portion of it protrude into the gap between the glass assembly 10 and the guide rail 11, after injection molding in the first edge-sealing injection chamber 130, the edge of the edge-sealing 30 located between the end of the guide rail 11 and the lower end face of the glass assembly 10 can also be recessed into the guide rail 11, thereby preventing the edge of the edge-sealing 30 from being exposed. Designers can adjust the specific shape and structure of the fourth decorative element 112 and the fifth decorative element 122 according to usage needs, and no specific limitations are made here.

[0108] Preferably, the fourth trimming body 112 includes a fourth trimming block, and the fifth trimming body 122 includes a fifth trimming block. More preferably, the fourth trimming body 112 and the fifth trimming body 122 are symmetrically arranged opposite to the glass assembly 10.

[0109] In one feasible embodiment, the fourth modification body 112 and the fifth modification body 122 are in clearance fit with the guide rail 11. By making the fourth modification body 112 and the fifth modification body 122 in clearance fit with the guide rail 11, the fourth modification body 112 and the fifth modification body 122 are prevented from affecting the guide rail 11.

[0110] The fourth modification 112 and the fifth modification 122 can be made of elastic or rigid materials, and no specific restrictions are imposed here.

[0111] In another feasible embodiment, the fourth modification 112 and the fifth modification 122 are both formed of elastic material, and the fourth modification 112, the fifth modification 122 and the guide rail 11 are in an interference fit.

[0112] By making the fourth trim body 112 and the fifth trim body 122 in an interference fit with the guide rail 11, the gap between the glass assembly 10 and the guide rail 11 is eliminated by the fourth trim body 112 and the fifth trim body 122, which plays an isolation role and prevents the injection molding material from flowing out. This also allows the edge of the edging 30 to be recessed into the guide rail 11, thereby preventing the edge of the edging 30 from being exposed.

[0113] Furthermore, the fourth decorative body 112 can be externally connected to the upper mold 110, or it can be integrally formed with the upper mold 110; no specific restrictions are imposed here. The fifth decorative body 122 can be externally connected to the lower mold 120, or it can be integrally formed with the lower mold 120; no specific restrictions are imposed here.

[0114] In embodiments of the present invention, such as Figure 5 In the embodiment shown, the first abutting portion 111 includes a first straight segment and a first arc segment disposed facing the guide rail 11, and an elastic abutting surface 20 is formed on the first straight segment and / or the first arc segment; and / or, the second abutting portion 121 includes a second straight segment and a second arc segment disposed facing the guide rail 11, and an elastic abutting surface 20 is formed on the second straight segment and / or the second arc segment.

[0115] Preferably, the first abutting portion 111 includes a first straight segment and a first arc segment disposed facing the guide rail 11, and an elastic abutting surface 20 is formed on the first straight segment and the first arc segment; and the second abutting portion 121 includes a second straight segment and a second arc segment disposed facing the guide rail 11, and an elastic abutting surface 20 is formed on the second straight segment and the second arc segment.

[0116] By forming elastic abutment surfaces 20 on the first straight segment and the first arc segment, and forming elastic abutment surfaces 20 on the second straight segment and the second arc segment, the first abutment part 111 and the second abutment part 121 can float and abut against the guide rail 11. This can play an adaptive adjustment role according to the shape of the guide rail 11, avoiding the upper mold 110 and the lower mold 120 from being too tight after mold closing and damaging the guide rail 11, and also avoiding the problem of the upper mold 110 and the lower mold 120 being too loose after mold closing and causing flash, thus improving the injection molding quality of the guide rail 11.

[0117] Designers may adjust the specific shape and structure of the first abutment part 111 and the second abutment part 121 according to the needs of use, and no specific restrictions are imposed here.

[0118] Preferably, a first elastic layer facing the guide rail 11 is provided on the first abutting portion 111, and an elastic breaking surface 20 is formed by the first elastic layer. A second elastic layer facing the guide rail 11 is provided on the second abutting portion 121, and an elastic breaking surface 20 is formed by the second elastic layer.

[0119] In embodiments of the present invention, such as Figure 10 In the illustrated embodiment, the upper mold 110 is further provided with a first decorative groove 114, which connects to the first edge-sealing injection chamber 130. A first decorative tongue 113 can be formed within the first decorative groove 114 by injection molding through the edge-sealing 30. The first decorative tongue 113 is used to cover the gap between the guide rail 11 and the edge-sealing 30. And / or, the lower mold 120 is further provided with a second decorative groove 125, which connects to the first edge-sealing injection chamber 130. A second decorative tongue 123 can be formed within the second decorative groove 125 by injection molding through the edge-sealing 30. The second decorative tongue 123 is used to cover the gap between the guide rail 11 and the edge-sealing 30. Preferably, the upper mold 110 is provided with a first decorative groove 114, and the lower mold 120 is also provided with a second decorative groove 125.

[0120] By providing a first decorative groove 114 on the upper mold 110 and connecting the first decorative groove 114 to the first edge-sealing injection chamber 130, injection material can be simultaneously injected into the first decorative groove 114 to form a first decorative tongue 113 during injection molding in the first edge-sealing injection chamber 130. After demolding of the upper mold 110, the first decorative tongue 113 is tilted towards the guide rail 11, thereby covering the gap between the guide rail 11 and the edge 30 and achieving an aesthetic effect.

[0121] Furthermore, a second decorative groove 125 is provided on the lower mold 120, and the second decorative groove 125 is connected to the second edge-sealing injection chamber 150. This allows the injection material to be simultaneously injected into the second decorative groove 125 to form the second decorative tongue 123 during injection molding in the second edge-sealing injection chamber 150. After demolding from the lower mold 120, the second decorative tongue 123 is tilted towards the guide rail 11, thus covering the gap between the guide rail 11 and the edge-sealing 30, thereby achieving an aesthetic effect.

[0122] Designers can adjust the specific shape and structure of the first trimming groove 114 and the second trimming groove 125 according to the needs of use, and no specific limitations are imposed here. Preferably, the first trimming groove 114 and the second trimming groove 125 are arranged approximately symmetrically with respect to the glass assembly 10.

[0123] In embodiments of the present invention, such as Figure 4 In the embodiment shown, the lower mold 120 is also provided with an injection channel 124, which is embedded inside the lower mold 120 and connects the first edge-sealing injection chamber 130 and the second edge-sealing injection chamber 150.

[0124] By embedding the injection channel 124 inside the lower mold 120, the injection channel 124 forms a "suspended" channel on the lower mold 120, so that the injection material injected into the first edge-sealing injection chamber 130 does not need to pass through the lower end face of the glass assembly 10 to reach the second edge-sealing injection chamber 150, thereby avoiding the injection material remaining on the lower surface of the glass assembly 10.

[0125] Furthermore, such as Figure 4 In the embodiment shown, the glass assembly 10 is further provided with at least one connector 12, and the lower mold 120 is provided with at least one slot. The slot is correspondingly provided with the connector 12, and the slot is connected to the second edge-sealing injection molding chamber 150. The slot is used to place the connector 12.

[0126] By placing the connector 12 in the second edge-sealing injection chamber 150, after injection molding in the second edge-sealing injection chamber 150, the edge formed by injection molding 30 can fix the connector 12 to the glass assembly 10, which helps to fix the guide rail 11 and each connector 12 at the same time through one injection molding, significantly improving manufacturing efficiency.

[0127] Furthermore, when the lower mold 120 is demolded, the injection channel 124 can automatically detach along with the lower mold 120, reducing the need for gate cutting and also reducing the risk of scratching the glass.

[0128] Designers can adjust the specific structure of connector 12 according to usage needs, and no specific restrictions are imposed here. Preferably, connector 12 is a nail post.

[0129] In embodiments of the present invention, such as Figure 8 and Figure 9 In the embodiment shown, the lower mold 120 is further provided with a lower limiting structure 300, which can limit the first lower elastic block 220 radially along the glass assembly 10.

[0130] By setting a lower limit structure 300 on the lower mold 120, the lower limit structure 300 can limit the first lower elastic block 220, thereby preventing the first lower elastic block 220 from moving around and improving the stability of the first lower elastic block 220. Designers can adjust the specific structure of the lower limit structure 300 according to the needs of use, and no specific restrictions are made here.

[0131] Preferably, the lower limit structure 300 includes a plurality of limit blocks disposed on the lower mold 120, each limit block being disposed on one or both sides of the first lower elastic block 220 to perform a limiting function.

[0132] More preferably, the setting height of the limiting block is lower than the setting height of the first lower elastic block 220, thereby avoiding affecting the adaptive adjustment amount of the elastic bearing surface 20 of the first lower elastic block 220.

[0133] In embodiments of the present invention, such as Figure 11 In the embodiment shown, the mold body 100 also includes a floating mechanism 400 disposed on the lower mold 120. The floating mechanism 400 is connected to the first edge-sealing injection chamber 130 and is used to adjust the floating based on the pressure in the first edge-sealing injection chamber 130.

[0134] By setting a floating mechanism 400 on the lower mold 120, the lower mold 120 can float and adjust under pressure, which significantly improves the adaptability of the lower mold 120.

[0135] In one feasible embodiment, the floating mechanism 400 includes at least one floating elastic block, which is embedded in the lower mold 120 and communicates with the first edge-sealing injection cavity 130.

[0136] By connecting the floating elastic block to the first edge-sealing injection chamber 130, when the pressure inside the first edge-sealing injection chamber 130 increases to a preset value, the floating elastic block can be compressed by the pressure, thereby increasing the volume of the first edge-sealing injection chamber 130 and playing the role of automatic pressure relief, so that the pressure inside the first edge-sealing injection chamber 130 does not exceed the target value, and has a better adaptive adjustment function.

[0137] Designers can adjust the adjustment rules of the floating elastic block according to the usage requirements, and no specific restrictions are imposed here. For example, when the pressure in the first edge-sealing injection chamber 130 reaches 20 bar, the thickness of the floating elastic block changes by 0.2 mm; when the pressure in the first edge-sealing injection chamber 130 reaches 30 bar, the thickness of the floating elastic block changes by 0.5 mm; and when the pressure in the first edge-sealing injection chamber 130 reaches 40 bar, the thickness of the floating elastic block changes by 0.8 mm.

[0138] In another feasible embodiment, the floating mechanism 400 includes at least one floating core and a pressure sensor. The pressure sensor is electrically connected to the floating core and is disposed in the first edge-sealing injection chamber 130. The floating core is embedded in the lower mold 120 and communicates with the first edge-sealing injection chamber 130. The floating core is used for floating adjustment based on the pressure signal of the pressure sensor.

[0139] Of course, in other feasible embodiments, designers may adjust the specific structure of the floating mechanism 400 according to the needs of use, and no specific restrictions are imposed here.
