This application provides a structural component, a foaming assembly, and an air conditioner for foaming. The structural component includes: a main body with a foaming cavity for accommodating foaming material; and an exhaust section connected to the main body and arranged circumferentially along the opening of the foaming cavity. The exhaust section has multiple protrusions spaced apart circumferentially along the foaming cavity, the protrusions being configured to abut against an upper mold so that the structural component can be pressed between the upper and lower molds; an exhaust gap communicating with the foaming cavity is formed between adjacent protrusions, the exhaust gap being configured to communicate with the external space. By directly setting the exhaust gap on the structural component, there is no need to reserve a gap between the structural component and the upper mold, allowing the structural component to be pressed between the upper and lower molds.

Description

Technical Field

[0001] This application relates to, but is not limited to, the field of foaming technology, specifically to a structural component, foaming assembly, and air conditioner for foaming. Background Technology

[0002] In the molding process of foamed components, the structural component is placed between the upper and lower molds. The structural component has a foaming cavity, and foaming material is injected into the foaming cavity to form a foamed part through foaming. The molded foamed part and the structural component are then integrated to form a foamed component. In related technologies, such as Figure 11 and Figure 12 As shown, a certain gap needs to be reserved between structural component 1 and upper mold 3 for overflow and venting. Overflow and venting directly affect the quality of foamed component 2. Since structural component 1 may warp and deform, and dimensional deviations are unavoidable, the size of the venting gap 122 between structural component 1 and mold is unstable, which can easily cause the quality of foamed component 2 to be unstable.

Detailed Implementation

[0019] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0020] This application provides a structural component 1 for foaming, including: a main body 11 and an exhaust section 12, such as... Figure 15 As shown.

[0021] like Figure 15 As shown, the main body 11 has a foaming cavity 110 for accommodating foamed material. An exhaust vent 12 is connected to the main body 11 and is arranged circumferentially along the opening of the foaming cavity 110. The exhaust vent 12 has a plurality of protrusions 121 spaced apart circumferentially along the foaming cavity 110. The plurality of protrusions 121 are configured to abut against the upper mold 3, so that the structural member 1 can be pressed between the upper mold 3 and the lower mold 4. An exhaust gap 122 communicating with the foaming cavity 110 is formed between adjacent protrusions 121, and the exhaust gap 122 is configured to communicate with the external space.

[0022] In related technologies, such as Figure 11 and Figure 12 As shown, a certain gap needs to be reserved between structural component 1 and upper mold 3 for overflow and venting. Overflow and venting directly affect the quality of foamed component 2. Since structural component 1 may warp and deform, and dimensional deviations are unavoidable, the size of the venting gap 122 between structural component 1 and mold is unstable, which can easily cause the quality of foamed component 2 to be unstable.

[0023] In this embodiment, the exhaust gap 122 is directly set on the structural component 1, such as... Figure 13 and Figure 14 As shown, there is no need to leave a gap between the structural component 1 and the upper mold 3, so that the structural component 1 can be pressed between the upper mold 3 and the lower mold 4. This can improve the problem of unstable size of the venting gap 122 caused by warping or dimensional deviation of the structural component 1, thereby helping to improve the quality stability of the foamed part 2.

[0024] The multiple protrusions 121 can be evenly spaced or non-evenly spaced, and can be reasonably adjusted according to the specific structure of the structural component 1 and the foaming component 2.

[0025] The connection between the venting gap 122 and the external space is unrestricted. It can be that the entire structural component 1 is located within the cavity enclosed by the upper mold 3 and the lower mold 4, with an air passage gap communicating with the venting gap 122 at the joint between the upper mold 3 and the lower mold 4. Alternatively, the main body 11 of the structural component 1 is located within the cavity enclosed by the upper mold 3 and the lower mold 4, with the venting section 12 sandwiched between the joint surfaces of the upper mold 3 and the lower mold 4, and the venting gap 122 directly communicating with the external space.

[0026] In other embodiments, the protrusion 121 can also be provided on the upper mold 3 or the lower mold 4, so that the venting gap 122 is located on the mold, and the structural component 1 is pressed between the upper mold 3 and the lower mold 4. This can also improve the problem of unstable size of the venting gap 122 caused by warping or dimensional deviation of the structural component 1, thereby helping to improve the quality stability of the foamed part 2.

[0027] In some exemplary embodiments, structural component 1 is provided with an overflow surface 130, which is located at the opening of the foaming cavity 110 and adjacent to the foaming cavity 110. The width of the overflow surface 130 is less than or equal to 2 mm. Structural component 1 is the skeleton of the foaming assembly and is used to contain the foaming material during the foaming process. After the foaming material is foamed, molded, and cured, it is connected to the structural component.

[0028] In related technologies, due to the foaming characteristics of the foaming material itself, there will be a phenomenon of glue overflow (burrs). The overflow is difficult to handle, which leads to a decrease in the quality of the foamed components and problems with the appearance of the parts. The main reason why the overflow is difficult to handle is that the overflow surface 130 of the structural component 1 is relatively wide (usually greater than 2mm), resulting in a large area covered by the overflow, making it difficult to maintain neatness and consistency when removing the overflow surface.

[0029] Therefore, this application embodiment improves the structure of the foaming component 1 by reducing the width of the overflow surface 130 to no more than 2mm, thereby reducing the coverage area of ​​the overflow. This facilitates neatness and consistency during overflow removal, reducing the cost of overflow removal and improving the aesthetics of the overflow surface 130 after removal, thus enhancing the quality of the foamed component. Furthermore, the narrower overflow surface 130 reduces the venting path length during the foaming process, facilitating venting and preventing poor foam adhesion and uneven overflow that could lead to unsatisfactory appearance. This improves the stability of the foaming quality and reduces the adverse effects of overflow warping.

[0030] Since the venting area is accompanied by adhesive overflow, the inner surface of the venting gap 122 forms at least a portion of the adhesive overflow surface 130 of the structural component. By setting the venting path length of the venting gap 122 (i.e., the length of the venting gap 122 along the venting direction) within a range of no more than 2 mm, the width of the adhesive overflow surface 130 at this location can be made no more than 2 mm.

[0031] The shape / width of the overflow surface 130 in different parts can be the same or different, and can be reasonably adjusted according to the specific structure of structural component 1 and foam component 2.

[0032] In some embodiments, the position and shape of the adhesive overflow surface 130 may change with the shape of the structural member 1 and the foaming cavity 110. Therefore, the width of the adhesive overflow surface 130 being less than or equal to 2 mm means that the width of all adhesive overflow surfaces 130 is less than or equal to 2 mm. In other words, the maximum width of the adhesive overflow surface 130 is less than or equal to 2 mm.

[0033] In some exemplary embodiments, the width of the adhesive overflow surface 130 may be in the range of, but not limited to, 0.5 mm to 1.0 mm, such as 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, etc.

[0034] Verification showed that limiting the width of the excess adhesive surface 130 within the above-mentioned range resulted in a more stable quality of the foamed part 2, and the excess adhesive was easy to remove, leaving the excess adhesive surface 130 neat and aesthetically pleasing.

[0035] In some exemplary embodiments, the opening of the foam cavity 110 includes a first edge 141, such as... Figure 7 As shown. At least a portion of the cavity wall of the foaming cavity 110 corresponding to the first edge 141 extends obliquely towards the outer edge of the structural member 1, so that the foaming cavity 110 forms an open structure, as shown. Figure 2 As shown. The surface between the first edge 141 and the outer edge of the structural member 1 forms a first adhesive overflow surface 131, and the adhesive overflow surface 130 includes the first adhesive overflow surface 131, as shown. Figure 2 As shown.

[0036] The first edge 141 refers to the edge where the opening of the foam cavity 110 is relatively close to the outer edge of the structural member 1. In conventional designs, the cavity wall of the foam cavity 110 is usually parallel to the outer wall of the structure. However, in this embodiment, at least a portion of the cavity wall of the foam cavity 110 corresponding to the first edge 141 (at least a portion of the cavity wall located relatively to the outer edge) is set as an inclined surface, thus enlarging the opening of the foam cavity 110. This further reduces the distance between the first edge 141 of the foam cavity 110 and the outer edge of the structural member 1, thereby reducing the width of the first overflow surface 131. Please refer to [further details to be added]. Figure 1 and Figure 2 The width W1 of the overflow adhesive surface 130 located on the upper right side is reduced from 2.9mm to 1mm, and the width W2 of the overflow adhesive surface 130 located on the lower right side is reduced from 2.7mm to 1mm.

[0037] The first edge 141 can be a part of the opening of the foam cavity 110 (i.e., only part of the edge of the opening of the foam cavity 110 is close to the outer edge of the structural member 1), or it can be the entire opening of the foam cavity 110 (i.e., the circumferential edge of the opening of the foam cavity 110 is close to the outer edge of the structural member 1).

[0038] In some exemplary embodiments, the opening of the foam cavity 110 includes a second edge 142, such as Figure 2 As shown, the surface of structural component 1 is provided with an overflow groove 113. The overflow groove 113 is located on the surface of the side where the opening of the foaming cavity 110 is located. The surface between the second edge 142 and the groove opening of the overflow groove 113 forms a second overflow surface 132. The overflow surface 130 includes the second overflow surface 132, as shown. Figure 2 As shown.

[0039] In conventional designs, at least a portion of the opening of some foaming cavities 110 (i.e., the second edge 142) has a large gap with the outer edge of the structural member 1, resulting in a relatively wide overflow surface 130 at the second edge 142. Due to the large gap, it is not suitable to reduce the width of the overflow surface 130 at the second edge 142 by setting a slope. Therefore, this embodiment uses an overflow groove 113 to interrupt the flow path of the overflow at the second edge 142, ensuring that the overflow can only flow to the overflow groove 113 and cannot continue flowing further. Thus, the overflow surface 130 at the second edge 142 is reduced from the portion between the second edge 142 and the outer edge of the structural member 1 to the portion between the overflow groove 113 and the second edge 142, thereby achieving the goal of reducing the width of the overflow surface 130. Please refer to [further details]. Figure 1 and Figure 2 The width W3 of the overflow adhesive surface 130 located on the upper left side is reduced to 0.5mm.

[0040] By controlling the distance between the glue overflow groove 113 and the second edge 142 to no more than 2 mm, the width of the second glue overflow surface 132 can be controlled to no more than 2 mm. Furthermore, the glue overflow within the glue overflow groove 113 accumulates easily and is thus easier to handle.

[0041] The second edge 142 can be a part of the opening of the foam cavity 110 (i.e., only part of the edge of the opening of the foam cavity 110 is far from the outer edge of the structural member 1), or it can be the entire opening of the foam cavity 110 (i.e., the circumferential edge of the opening of the foam cavity 110 is far from the outer edge of the structural member 1).

[0042] Therefore, when the circumferential edges of the opening of the foaming cavity 110 are all first edges 141, the width of the overflow surface 130 can be reduced by using an inclined cavity wall. When the circumferential edges of the opening of the foaming cavity 110 are all second edges 142, the width of the overflow surface 130 can be reduced by using an overflow groove 113. When the circumferential edges of the opening of the foaming cavity 110 include both first edges 141 and second edges 142, the width of the overflow surface 130 can be reduced at the first edge 141 by using an inclined cavity wall, and at the second edge 142 by using an overflow groove 113.

[0043] In some embodiments, the circumferential edge of the opening of the foaming cavity 110 may also include a third edge. The overflow surface 130 corresponding to the third edge may reduce the width of the overflow surface 130 by neither using the method of tilting the cavity wall nor by using the method of setting the overflow groove 113, but by directly thinning or setting a step.

[0044] In other embodiments, masking tape can be applied to the excess adhesive surface 130 of the structural component 1, and the excess adhesive can be removed by peeling off the masking tape after molding. The masking tape should not extend beyond the outer edge of the structural component 1.

[0045] In some exemplary embodiments, such as Figure 15 As shown, the plurality of protrusions 121 include at least one of the following: a rib extending along the exhaust direction of the exhaust portion 12, and a boss extending along the length direction of the exhaust portion 12. This design has a simple structure and is easy to process and form. Of course, the structural form of the protrusions 121 is not limited to this, and can also be other shapes, which will not be listed here.

[0046] In some exemplary embodiments, the number of foaming cavities 110 is two, and the two foaming cavities 110 are respectively referred to as the first foaming cavity 111 (e.g., Figure 19 (As shown in the figure) and the second foaming cavity (not shown in the figure; the cavity corresponding to the second insulation layer 62 is the second foaming cavity). The first foaming cavity 111 is recessed on one side of the thickness direction of the main body 11, and the first foaming cavity 111 is surrounded by the circumferential edge of the main body 11, as shown in the figure. Figure 3 The area corresponding to the first insulation layer 61. Therefore, the opening area of ​​the first foaming cavity 111 is relatively large, and the opening of the first foaming cavity 111 is relatively close to the outer edge of the structural member 1. Thus, at least part of the edge of the opening of the first foaming cavity 111 is the first edge 141.

[0047] The second foaming cavity is recessed on the other side of the thickness direction of the main body 11, and the second foaming cavity is a strip-shaped groove, as can be seen from... Figure 4 The area corresponding to the second insulation layer 62. Therefore, the opening area of ​​the second foaming cavity is small, and at least a portion of the opening of the second foaming cavity is far from the outer edge of the structural member 1. Thus, at least a portion of the edge of the opening of the second foaming cavity is the second edge 142.

[0048] Structural component 1 is also provided with an overflow hole 114 connecting the first foaming cavity 111 and the second foaming cavity, such as Figure 19 As shown. Therefore, during the foaming process, the foaming material can flow between the first foaming cavity 111 and the second foaming cavity, allowing double-sided foaming to be achieved in a single foaming process, resulting in an integrally foamed part 2. This simplifies the processing steps of the foamed component, reduces the risk of the foamed part 2 falling off, and improves the deformation resistance of the foamed component. An exhaust vent 12 is provided at the opening of the first foaming cavity 111 and / or the second foaming cavity, as shown in the reference. Figure 18 and Figure 19 As shown.

[0049] like Figure 1 , Figure 2 and Figure 14As shown in the embodiments of this application, a foaming component is also provided, including: a structural member 1 and a foaming member 2 as described in any of the above embodiments. The foaming member 2 is connected to the structural member 1 and fills the foaming cavity 110.

[0050] The foaming component provided in this application includes the foaming structural component 1 of any of the above embodiments, and therefore has all the above-mentioned beneficial effects, which will not be repeated here.

[0051] In some exemplary embodiments, such as Figures 1 to 10 As shown, the foamed component is an air guide plate assembly, structural component 1 is the air guide plate substrate 5, and foamed component 2 is the insulation layer 6. The resulting air guide plate assembly has good appearance consistency, which is beneficial to improving the yield and aesthetics of the air guide plate assembly.

[0052] In some exemplary embodiments, there are two foaming cavities 110, which are referred to as the first foaming cavity 111 and the second foaming cavity, respectively.

[0053] like Figure 19 As shown, the first foaming cavity 111 is recessed on one side of the thickness direction of the air guide plate substrate 5. The second foaming cavity is recessed on the other side of the thickness direction of the air guide plate substrate 5. The foaming component 2 includes a first insulation layer 61 and a second insulation layer 62, as shown... Figure 1 and Figure 2 As shown. The first insulation layer 61 fills the first foaming cavity 111, and the second insulation layer 62 fills the second foaming cavity.

[0054] This design ensures that both sides of the air guide plate have insulation layers 6, which improves the insulation effect. Furthermore, the narrow adhesive overflow surface 130 of the air guide plate assembly facilitates adhesive overflow management, improves the stability of the foaming quality of the air guide plate assembly, and optimizes its appearance.

[0055] In some exemplary embodiments, the air guide plate substrate 5 is provided with an overflow hole 114 connecting the first foaming cavity 111 and the second foaming cavity, such as... Figure 19 As shown. Therefore, during the foaming process, the foaming material can flow between the first foaming cavity 111 and the second foaming cavity, allowing double-sided foaming to be achieved in a single foaming process, resulting in an integrally foamed insulation component, which simplifies the processing steps of the air guide plate. Furthermore, the two insulation layers 6 are integrally connected together, as shown... Figure 1 and Figure 2 As shown, they can restrain each other, which helps to reduce the risk of insulation components falling off and also helps to improve the deformation resistance of the air guide plate.

[0056] In one embodiment, at least a portion of the edge of the opening of the first foaming cavity 111 is a first edge 141, such as... Figure 2As shown. The opening of the second foaming chamber includes a first edge 141 and a second edge 142, as... Figure 7 As shown. The second foaming chamber is U-shaped, including two strip-shaped grooves extending along the width direction of the air guide plate base 5 and a strip-shaped groove extending along the length direction of the air guide plate base 5, as shown. Figure 4 As shown. The long side of the outer edge of this type of U-shaped groove can be the second edge 142, and the two short sides can be the first edge 141. The inner edge of this type of U-shaped groove can be the second edge 142.

[0057] Figure 1 , Figure 5 , Figure 7 , Figure 9 , Figure 16 and Figure 17 The diagram illustrates the structure of the air guide plate assembly before the improvement. Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 8 , Figure 10 , Figure 18 and Figure 19 The diagram illustrates the improved structure of the air guide plate assembly.

[0058] The adhesive overflow surface 130 of the air guide plate substrate 5 includes a first plate adhesive overflow surface surrounding the opening of the first foaming cavity 111 and a second plate adhesive overflow surface surrounding the opening of the second foaming cavity.

[0059] Among them, such as Figure 3 As shown, the first panel's adhesive overflow surface includes a first long-side adhesive overflow surface 501, a second long-side adhesive overflow surface 502, a first short-side adhesive overflow surface 503, and a second short-side adhesive overflow surface 504. The first long-side adhesive overflow surface 501 and the second long-side adhesive overflow surface 502 are spaced apart on both sides of the first foaming cavity 111 along the width direction of the air guide plate base 5, and both extend along the length direction of the air guide plate base 5. The first short-side adhesive overflow surface 503 and the second short-side adhesive overflow surface 504 are spaced apart on both sides of the first foaming cavity 111 along the length direction of the air guide plate base 5, and both extend along the width direction of the air guide plate base 5.

[0060] like Figure 4As shown, the second panel's adhesive overflow surface includes a third long-side adhesive overflow surface 505, a fourth long-side adhesive overflow surface 506, a third middle-side adhesive overflow surface 507, a fourth middle-side adhesive overflow surface 508, a fifth middle-side adhesive overflow surface 509, a sixth middle-side adhesive overflow surface 510, a third short-side adhesive overflow surface 511, and a fourth short-side adhesive overflow surface 512. The third long-side adhesive overflow surface 505 and the fourth long-side adhesive overflow surface 506 are spaced apart on both sides of the second foaming cavity along the width direction of the air guide plate substrate 5, and both extend along the length direction of the air guide plate substrate 5. Specifically, the third long-side adhesive overflow surface 505 is located on the side of the second foaming cavity closer to the rotation axis of the air guide plate substrate 5, and the fourth long-side adhesive overflow surface 506 is located on the side of the second foaming cavity away from the rotation axis of the air guide plate substrate 5; therefore, the length of the third long-side adhesive overflow surface 505 is greater than the length of the fourth long-side adhesive overflow surface 506. The third, fourth, fifth, and sixth middle edge adhesive overflow surfaces 507, 508, 509, and 510 all extend along the width direction of the air guide plate base 5 and are sequentially spaced along the length direction of the air guide plate base 5. The length of the third middle edge adhesive overflow surface 507 is greater than the length of the fourth middle edge adhesive overflow surface 508, and the length of the fifth middle edge adhesive overflow surface 509 is greater than the length of the sixth middle edge adhesive overflow surface 510. The third short edge adhesive overflow surface 511 and the fourth short edge adhesive overflow surface 512 are spaced apart at both ends of the length direction of the first foaming cavity 111 along the length direction of the air guide plate base 5, and both extend along the length direction of the air guide plate base 5.

[0061] In one embodiment, combined Figure 5 , Figure 7 and Figure 9 It can be seen that before the improvement of the air guide plate assembly, the width W4 of the first long side overflow surface 501 was 3.3mm, and the width W8 of the first short side overflow surface 503 was 2.7mm. The overflow surface 130 corresponding to the inner edge of the opening of the second mounting cavity (i.e., the second edge 142) is connected as one piece, that is: the entire arc surface 513 adjacent to the inner edge of the U-shaped groove is an overflow surface, and there are no separate fourth middle side overflow surface 508, fourth long side overflow surface 506, and fifth middle side overflow surface 509. The width W9 of the third middle side overflow surface 507 is 2.9mm.

[0062] Combination Figure 6 , Figure 8 and Figure 10As can be seen, after the improvement of the air guide plate assembly, due to the setting of the step, the width W4 of the first long side overflow surface 501 is reduced to 1mm. Due to the inclined cavity wall corresponding to the first edge 141, the width W8 of the first short side overflow surface 503 is reduced to 1mm. Due to the inclined cavity wall corresponding to the first edge 141, the width W9 of the third middle side overflow surface 507 is reduced to 1mm. Due to the setting of the overflow groove 113, the width W6 of the third long side overflow surface 505 is reduced to 1mm. Due to the setting of the overflow groove 113, the overflow surface corresponding to the inner edge of the opening of the second mounting cavity (i.e., the second edge 142) is separated by the overflow groove 113, forming a separate fourth middle side overflow surface 508, fourth long side overflow surface 506, and fifth middle side overflow surface 509, and the width W7 of the fourth long side overflow surface 506 is 0.5mm, and the width W10 of the fourth middle side overflow surface 508 is 1mm.

[0063] Thus, the maximum width of the overflow surface 130 of the air guide plate assembly is less than 2mm, that is, the width of all overflow surfaces 130 is less than or equal to 2mm.
