Description

Technical Field

[0001] The present invention relates to the technical field of molds, and in particular to an edge-wrapped injection mold for a glass assembly. Background Art

[0002] Glass edging assemblies are used in automobiles, passenger cars, buses, taxis and other vehicles. Glass edging assemblies are usually manufactured by integral injection molding, which helps to speed up the manufacturing efficiency of the glass edging assembly and improve the quality of the glass edging assembly. In this field, guide rails, glass, iron parts, etc. with a black high-gloss appearance are placed together in a mold, and then molten plastic is injected into the mold by an injection molding machine. After the injection molding material cools, the injection molding material connects the glass, guide rails, and iron parts together. After the mold is opened, the glass edging assembly can be taken out. Glass is a fragile and explosive material, especially laminated glass. The lower strength of laminated glass makes it more prone to cracking. Due to the instability of glass, very high requirements are placed on the structure and precision of the mold used for edging injection molding.

[0003] The typical glass thickness tolerance is limited to ±0.2mm, and the glass surface fluctuation is limited to ±0.75mm. Injection molds are designed to ensure rigid contact between the glass surface around the glass rim and the upper and lower mold cores, ensuring mold sealing. The typical sealing width is 7mm-25mm. If the glass thickness and surface tolerances cannot be guaranteed, the glass can easily be crushed during mold closing and injection molding, or it can easily break under stress during the injection molding process. This not only affects product yield and production efficiency, but also easily scratches the mold surface. Therefore, how to better adapt injection molds to glass surface fluctuations to improve product quality has become a pressing technical issue. Summary of the Invention

[0058] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0059] Please refer to Figures 1 to 11As shown, an embodiment of the present invention provides a rim injection mold for a glass assembly, which includes a mold body 100 and an adaptive elastic structure 200. The mold body 100 includes a detachable upper mold 110 and a lower mold 120. When the upper mold 110 and the lower mold 120 are combined, a first rim injection molding chamber 130 is formed around at least a portion of the glass assembly 10; the adaptive elastic structure 200 is arranged on the upper mold 110 and / or the lower mold 120, and the adaptive elastic structure 200 is formed with an elastic rest surface 20 facing the glass assembly 10, and the elastic rest surface 20 can float against the glass assembly 10.

[0060] Generally speaking, when the hemming injection mold for a glass assembly is used, the glass assembly 10 to be hemmed is placed at a target position of the lower mold 120, and the attachments on the glass assembly 10 can be simultaneously placed on the lower mold 120. The upper mold 110 and the lower mold 120 are then closed together, thereby forming a first hemming injection molding cavity 130 that surrounds at least a portion of the glass assembly 10. By injecting the hot-melt material into the first hemming injection molding cavity 130, the hemming structure can be formed on the glass assembly 10 through a single injection molding process, and the attachments can be simultaneously injection-molded and fixed to the glass assembly 10, significantly improving the processing efficiency of the hemming 30.

[0061] In addition, an adaptive elastic structure 200 is also provided on the upper mold 110 and / or the lower mold 120. The adaptive elastic structure 200 can form an elastic break surface 20 facing the glass assembly 10. The elastic break surface 20 can float against the glass assembly 10, so that it can play an adaptive adjustment role according to the surface shape of the glass assembly 10, so that the injection mold of the present invention can better adapt to the fluctuation of the glass surface, avoid the upper mold 110 and the lower mold 120 rigidly abutting against the glass assembly 10 after the mold is closed, and cause damage to the glass assembly 10, thereby reducing the risk of damage to the glass assembly 10, and improving the finished product rate of the edging 30, thereby improving product quality.

[0062] In the embodiment of the present invention, designers can adjust the specific structure of the glass assembly 10 according to usage requirements. For example, the glass assembly 10 includes but is not limited to single glass or laminated glass, which is not specifically limited here.

[0063] In one possible embodiment of the present invention, Figure 1 and Figure 6 In the illustrated embodiment, the upper mold 110 includes an upper positioning portion 140 protruding toward the glass assembly 10 . A rigid break surface facing the glass assembly 10 is formed on the upper positioning portion 140 , and the rigid break surface can abut against the glass assembly 10 .

[0064] By setting an upper positioning portion 140 on the upper mold 110, the rigid supporting surface of the upper positioning portion 140 can be abutted against the glass assembly 10, thereby more stably fixing the glass assembly 10 and avoiding the problem of movement of the glass assembly 10 during the injection molding process of the edging 30.

[0065] The designer can adjust the specific shape, structure and size of the upper positioning portion 140 according to the use requirements, and no specific limitation is imposed here. Preferably, the cross section of the upper positioning portion 140 is substantially rectangular.

[0066] Furthermore, along the circumference of the glass assembly 10, as shown in FIG. Figure 7 In the embodiment shown, the upper positioning portion 140 can be gradually configured so that the upper positioning portion 140 has different radial dimensions, thereby being able to adjust the size and coverage of the first edge-wrapping injection molding cavity 130 according to preset targets to better meet the needs of the edge wrapping 30 .

[0067] Furthermore, along the circumference of the glass assembly 10 , the upper positioning portion 140 may be continuously arranged, or the upper positioning portion 140 may be formed by splicing a plurality of upper positioning blocks, which is not specifically limited herein.

[0068] In an embodiment of the present invention, Figure 2 In the illustrated embodiment, 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 portion 140 , and an elastic support surface 20 is formed on the upper elastic block 210 .

[0069] By arranging the upper elastic block 210 on the upper mold 110, the elastic breaking surface 20 of the upper elastic block 210 can float and abut against the upper end surface of the glass assembly 10, thereby playing a floating adjustment role, which is convenient for absorbing the fluctuation tolerance of the thickness and profile of the glass assembly 10, so that the upper mold 110 can better adapt to the upper end surface of the glass assembly 10, which helps to reduce the risk of the glass assembly 10 being broken.

[0070] The designer can adjust the specific shape, structure and size of the upper elastic block 210 according to the use requirements, and no specific limitation is imposed here. Preferably, the cross section of the upper elastic block 210 is substantially rectangular.

[0071] Furthermore, the upper elastic block 210 may be gradually arranged along the circumference of the glass assembly 10 , so that the elastic abutment surface 20 of the upper elastic block 210 has different radial dimensions, thereby being able to better abut against different positions of 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 formed by splicing a plurality of elastic blocks, which is not specifically limited herein.

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

[0074] In another possible embodiment of the present invention, Figure 3 and Figure 9 In the illustrated embodiment, the upper mold 110 further includes an upper positioning portion 140 protruding toward the glass assembly 10, and a first modifying body 141 disposed on the upper positioning portion 140. At least a portion of the first modifying body 141 protrudes into the first edge-molding cavity 130. The first modifying body 141 is formed with a rigid support surface and / or an elastic support surface 20 facing the glass assembly 10.

[0075] By arranging the first modification body 141 on the upper positioning portion 140 and protruding at least a portion of the first modification body 141 in the first hemming injection molding cavity 130 , the edge of the hemming 30 on the upper end surface of the glass assembly 10 can be recessed into the hemming 30 body, thereby preventing the edge of the hemming 30 from being exposed. This improves the aesthetics of the edge of the hemming 30 and eliminates the need for repairing burrs and scraping primer.

[0076] In one embodiment, the first trimming body 141 includes a first trimming elastic block. Specifically, the first trimming elastic block is fitted onto the upper positioning portion 140 , and one end of the first trimming elastic block, which is adjacent to the first edge-molding cavity 130 , is protruded into the first edge-molding cavity 130 . This creates a concave structure between the edge-molding 30 and the upper end surface of the glass assembly 10 , thereby eliminating the problem of flash.

[0077] In another specific embodiment, the first modification body 141 includes a first mold slider. Specifically, the first mold slider is mounted on the upper positioning portion 140, and one end of the first mold slider, which is adjacent to the first edge-molding cavity 130, is projected into the first edge-molding cavity 130. This forms a concave structure between the edge 30 and the upper end surface of the glass assembly 10, thereby eliminating the problem of flash.

[0078] Furthermore, in order to avoid sudden changes in shape that affect the edge quality of the edging 30, a chamfer is provided on the first modification elastic block or the first mold slider to ensure a smooth transition between the end of the first modification elastic block or the first mold slider and the upper positioning portion 140. No specific restrictions are imposed here.

[0079] The designer can adjust the specific shape of the first modification elastic block or the first mold slider according to the use requirements, and no specific limitation is imposed here. Preferably, the first modification elastic block or the first mold slider is constructed in a plate shape.

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

[0081] By arranging the first lower elastic block 220 on the lower mold 120, the elastic fracture 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, which is convenient for absorbing the fluctuation tolerance of the thickness and profile of the glass assembly 10, so that the lower mold 120 can better adapt to the lower end surface of the glass assembly 10, which helps to reduce the risk of the glass assembly 10 being crushed.

[0082] Designers can adjust the specific shape, structure and size of the first lower elastic block 220 according to usage needs, and no specific restrictions are imposed here. Preferably, the cross section of the first lower elastic block 220 is substantially rectangular.

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

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

[0085] In an embodiment of the present invention, Figure 2 、 Figure 3 and Figure 4 In the embodiment shown, the adaptive elastic structure 200 also includes a second lower elastic block 230 arranged on the lower mold 120. The second lower elastic block 230 is spaced apart and arranged on the inner side of the first lower elastic block 220. The second lower elastic block 230 is formed with an elastic support surface 20 facing the glass assembly 10. The gap between the second lower elastic block 230 and the first lower elastic block 220 forms a second edge-wrapped injection molding chamber 150.

[0086] By spacing the second lower elastic block 230 from the first lower elastic block 220 , a second edge-wrapping injection molding chamber 150 can be formed. The second edge-wrapping injection molding chamber 150 can be used to form an edge-wrapping structure on the lower end surface of the glass assembly 10 , thereby better meeting the setting requirements of the edge-wrapping 30 on the glass assembly 10 .

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

[0088] In an embodiment of the present invention, Figure 3 In the illustrated embodiment, a second modifying body 221 is provided on the first lower elastic block 220, and at least a portion of the second modifying body 221 is protruded into the first edge-wrapped injection molding cavity 130 and / or the second edge-wrapped injection molding cavity 150; and / or a third modifying body 231 is provided on the second lower elastic block 230, and at least a portion of the second modifying body 221 is protruded into the second edge-wrapped injection molding cavity 150.

[0089] Preferably, at least part of the second trimming body 221 is respectively protruded in the first edge molding cavity 130 and the second edge molding cavity 150. In addition, a third trimming body 231 is provided on the second lower elastic block 230, and at least part of the second trimming body 221 is protruded in the second edge molding cavity 150.

[0090] By arranging the second modifying body 221 on the first lower elastic block 220 and protruding at least a portion of the second modifying body 221 in the first hemming injection molding chamber 130, the edge of the hemming 30 on the lower end surface of the glass assembly 10 can be recessed into the hemming 30 body, thereby preventing the edge of the hemming 30 from being exposed, thereby improving the aesthetics of the edge of the hemming 30 and achieving the effect of eliminating the need for repairing burrs and scraping primer.

[0091] Furthermore, at least a portion of the second modification body 221 is protruded into the second edging injection molding chamber 150 , so that the edge of the edging 30 on the lower end surface of the glass assembly 10 can be recessed into the edging body, thereby preventing the edge of the edging 30 from being exposed, thereby improving the aesthetics of the edge of the edging 30 and avoiding the need for repairing burrs and scraping primer.

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

[0093] In a specific embodiment, if Figure 3In the illustrated embodiment, the second modification body 221 includes two second modification elastic blocks, which are respectively arranged on the two side walls of the first lower elastic block 220 and protrude into the first edge injection molding cavity 130 and the second edge injection molding cavity 150 .

[0094] The second modified elastic block is externally connected to the side wall of the first lower elastic block 220 , or the second modified elastic block and the first lower elastic block 220 are integrally provided, which is not specifically limited here.

[0095] Further, such as Figure 3 In the illustrated embodiment, the third modification body 231 includes a third modification elastic block, which is disposed on a side wall of the second lower elastic block 230 and protrudes into the second edge-wrapping injection molding cavity 150 .

[0096] The third modified elastic block is externally connected to the side wall of the second lower elastic block 230 , or the third modified elastic block and the second lower elastic block 230 are integrally provided, which is not specifically limited here.

[0097] Of course, in other feasible embodiments, designers can adjust the specific configuration of the second modification body 221 and the third modification body 231 according to usage requirements, and no specific limitation is made here.

[0098] In an embodiment of the present invention, Figure 3 and Figure 4 In the illustrated embodiment, along the height direction, the projection of the upper positioning portion 140 is located within the projection range of the first lower elastic block 220 .

[0099] By ensuring that the projection of the upper positioning portion 140 is within the projection range of the first lower elastic block 220 , the first lower elastic block 220 has a larger support area than the upper positioning portion 140 , thereby avoiding shear force generated by the staggered arrangement between the upper positioning portion 140 and the first lower elastic block 220 , thereby reducing the risk of the glass assembly 10 being broken.

[0100] Designers can adjust the projected area of ​​the upper positioning portion 140 and the projected area of ​​the first lower elastic block 220 according to usage requirements, and no specific limitation is imposed herein.

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

[0102] By providing a first abutting portion 111 on the upper mold 110 and a second abutting portion 121 on the lower mold 120, the first abutting portion 111 and the second abutting portion 121 can cooperate and abut on both sides of the guide rail 11, thereby limiting the guide rail 11, so that the guide rail 11 can cooperate with the glass assembly 10 according to the preset position.

[0103] Moreover, after the upper mold 110 and the lower mold 120 are closed, at least a portion of the first edge-wrapped injection molding 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-wrapped injection molding cavity 130, a partial edge 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.

[0104] In an embodiment of the present invention, Figure 5 In the illustrated embodiment, the upper mold 110 is further provided with a fourth modification body 112, and at least a portion of the fourth modification body 112 is protruded in the gap between the glass assembly 10 and the guide rail 11; and / or, the lower mold 120 is further provided with a fifth modification body 122, and at least a portion of the fifth modification body 122 is protruded in the gap between the glass assembly 10 and the guide rail 11.

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

[0106] By providing the fourth modification body 112 and protruding at least a portion of the fourth modification body 112 in the gap between the glass assembly 10 and the guide rail 11, after injection molding in the first edge molding chamber 130, the edge of the edge 30 between the end of the guide rail 11 and the upper end surface of the glass assembly 10 can also be recessed into the guide rail 11, thereby preventing the edge of the edge 30 from being exposed, thereby improving the aesthetics of the edge of the edge 30 and eliminating the need for repairing burrs and scraping primer.

[0107] Similarly, by providing the fifth trimming body 122 and positioning at least a portion thereof protruding within the gap between the glass assembly 10 and the guide rail 11, the edge of the edging 30 located between the end of the guide rail 11 and the lower end surface of the glass assembly 10 can be recessed into the guide rail 11 after injection molding in the first edging injection molding chamber 130, thereby preventing the edge of the edging 30 from being exposed. Designers can adjust the specific shapes and structures of the fourth trimming body 112 and the fifth trimming body 122 according to specific needs and are not specifically limited here.

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

[0109] In one embodiment, the fourth and fifth modified bodies 112 and 122 are provided with a clearance fit to the guide rail 11. By providing a clearance fit to the fourth and fifth modified bodies 112 and 122 to the guide rail 11, the fourth and fifth modified bodies 112 and 122 are prevented from affecting the guide rail 11.

[0110] The fourth modified body 112 and the fifth modified body 122 can be made of elastic material or rigid material, which is not specifically limited here.

[0111] In another feasible embodiment, the fourth modified body 112 and the fifth modified body 122 are both formed by elastic materials, and the fourth modified body 112 and the fifth modified body 122 are interference fit with the guide rail 11 .

[0112] By providing an interference fit between the fourth and fifth modification bodies 112 and 122 and the guide rail 11, the fourth and fifth modification bodies 112 and 122 eliminate the gap between the glass assembly 10 and the guide rail 11, thereby providing isolation and preventing the injection molding material from flowing out. Furthermore, the edge of the edging 30 can be recessed into the guide rail 11, thereby preventing the edge of the edging 30 from being exposed.

[0113] Furthermore, the fourth modified body 112 may be externally connected to the upper mold 110 or integrally formed with the upper mold 110, without specific limitations. The fifth modified body 122 may be externally connected to the lower mold 120 or integrally formed with the lower mold 120, without specific limitations.

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

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

[0116] By forming elastic abutment surfaces 20 on the first straight section and the first arc section, and elastic abutment surfaces 20 on the second straight section and the second arc section, the first abutment portion 111 and the second abutment portion 121 can float and abut on the guide rail 11, and can play a role of adaptive adjustment according to the surface shape of the guide rail 11, thereby avoiding the upper mold 110 and the lower mold 120 from being too tight after the mold is closed and damaging the guide rail 11, and also avoiding the problem of flash caused by the upper mold 110 and the lower mold 120 being too loose after the mold is closed, thereby improving the injection molding quality of the guide rail 11.

[0117] Designers can adjust the specific shapes and structures of the first abutting portion 111 and the second abutting portion 121 according to usage requirements, and no specific limitation is imposed herein.

[0118] Preferably, the first abutting portion 111 is provided with a first elastic layer facing the guide rail 11, forming an elastic abutting surface 20. The second abutting portion 121 is provided with a second elastic layer facing the guide rail 11, forming an elastic abutting surface 20.

[0119] In an embodiment of the present invention, Figure 10 In the illustrated embodiment, the upper mold 110 is further provided with a first trimming groove 114, which communicates with the first edging injection molding cavity 130. A first trimming tongue 113 can be formed in the first trimming groove 114 by injection molding the edging 30. The first trimming tongue 113 is used to cover the gap between the guide rail 11 and the edging 30. And / or, the lower mold 120 is further provided with a second trimming groove 125, which communicates with the first edging injection molding cavity 130. A second trimming tongue 123 can be formed in the second trimming groove 125 by injection molding the edging 30. The second trimming tongue 123 is used to cover the gap between the guide rail 11 and the edging 30. Preferably, the upper mold 110 is provided with the first trimming groove 114, and the lower mold 120 is also provided with the second trimming groove 125.

[0120] By providing a first trimming groove 114 on the upper mold 110 and connecting it to the first edge-wrapping injection molding chamber 130, during injection molding in the first edge-wrapping injection molding chamber 130, the molding material can be simultaneously injected into the first trimming groove 114 to form the first trimming tongue 113. After the upper mold 110 is demolded, the first trimming tongue 113 is tilted toward the guide rail 11, and the first trimming tongue 113 is used to cover the gap between the guide rail 11 and the edge 30, thereby achieving a beautifying effect.

[0121] Furthermore, a second trimming groove 125 is provided on the lower mold 120 and is connected to the second edge-wrapping injection molding chamber 150. Thus, during the injection molding process in the second edge-wrapping injection molding chamber 150, the molding material can be simultaneously injected into the second trimming groove 125 to form the second trimming tongue 123. After the lower mold 120 is demolded, the second trimming tongue 123 is tilted toward the guide rail 11, thereby covering the gap between the guide rail 11 and the edge 30, thereby achieving a beautifying effect.

[0122] Designers can adjust the specific shapes and structures of the first trimming groove 114 and the second trimming groove 125 according to the needs of use, and no specific limitation is imposed here. Preferably, the first trimming groove 114 and the second trimming groove 125 are substantially symmetrically arranged relative to the glass assembly 10.

[0123] In an embodiment of the present invention, Figure 4 In the illustrated embodiment, the lower mold 120 is further provided with an injection channel 124 . The injection channel 124 is embedded in the lower mold 120 . The injection channel 124 communicates with the first edge-wrapped injection cavity 130 and the second edge-wrapped injection cavity 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-wrapped injection molding chamber 130 can reach the second edge-wrapped injection molding chamber 150 without passing through the lower end surface of the glass assembly 10, thereby avoiding the injection material from remaining on the lower surface of the glass assembly 10.

[0125] Further, such as Figure 4 In the embodiment shown, at least one connecting member 12 is further provided on the glass assembly 10, and at least one card slot is provided on the lower mold 120. The card slot is arranged corresponding to the connecting member 12, and the card slot is connected to the second edge injection molding chamber 150, and the card slot is used to place the connecting member 12.

[0126] By arranging the connecting member 12 in the second edging injection molding chamber 150, after injection molding in the second edging injection molding chamber 150, the edging 30 formed by injection molding can fix the connecting member 12 to the glass assembly 10, which helps to simultaneously fix the guide rail 11 and each connecting member 12 through one injection molding, thereby significantly improving manufacturing efficiency.

[0127] Furthermore, when the lower mold 120 is demolded, the injection channel 124 can automatically fall off along with the lower mold 120 , thereby reducing the gate cutting action and the risk of scratching the glass.

[0128] The designer can adjust the specific structure of the connecting member 12 according to the use requirements, and no specific limitation is made here. Preferably, the connecting member 12 is a nail post.

[0129] In an embodiment of the present invention, Figure 8 and Figure 9 In the illustrated embodiment, a lower limiting structure 300 is further provided on the lower mold 120 . The lower limiting structure 300 can limit the first lower elastic block 220 along the radial direction of the glass assembly 10 .

[0130] By providing the lower limiting structure 300 on the lower mold 120, the lower limiting structure 300 can limit the first lower elastic block 220, thereby preventing the first lower elastic block 220 from moving and improving the stability of the first lower elastic block 220. Designers can adjust the specific structure of the lower limiting structure 300 according to actual needs and are not specifically limited here.

[0131] Preferably, the lower limiting structure 300 includes a plurality of limiting blocks provided on the lower mold 120 , and each limiting block is provided on one side or both sides of the first lower elastic block 220 to play a limiting role.

[0132] More preferably, the setting height of the limit block is lower than the setting height of the first lower elastic block 220 , so as to avoid affecting the adaptive adjustment amount of the elastic supporting surface 20 of the first lower elastic block 220 .

[0133] In an embodiment of the present invention, Figure 11 In the illustrated embodiment, the mold body 100 further includes a floating mechanism 400 disposed on the lower mold 120 . The floating mechanism 400 is connected to the first edge-wrapped injection molding cavity 130 and is used for floating adjustment based on the pressure in the first edge-wrapped injection molding cavity 130 .

[0134] By arranging the floating mechanism 400 on the lower mold 120 , the lower mold 120 can be floated and adjusted under pressure, which significantly improves the adaptability of the lower mold 120 .

[0135] In a 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-wrapping injection molding cavity 130 .

[0136] By connecting the floating elastic block to the first edge-wrapped injection molding chamber 130, when the pressure in the first edge-wrapped injection molding 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-wrapped injection molding chamber 130, playing a role of automatic pressure relief, so that the pressure in the first edge-wrapped injection molding chamber 130 does not exceed the target value, and has a better adaptive adjustment effect.

[0137] Designers can adjust the floating elastic block's adjustment rules based on actual use, and there are no specific restrictions here. For example, when the pressure in the first edge-molding chamber 130 reaches 20 bar, the thickness of the floating elastic block changes by 0.2 mm; when the pressure in the first edge-molding 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-molding 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, which is electrically connected to the floating core. The pressure sensor is arranged in the first edge-wrapped injection molding chamber 130. The floating core is embedded in the lower mold 120 and connected to the first edge-wrapped injection molding chamber 130. The floating core is used to perform floating adjustment based on the pressure signal of the pressure sensor.

[0139] Of course, in other feasible embodiments, designers can adjust the specific structure of the floating mechanism 400 according to usage requirements, and no specific limitation is made here.
