Injection molding part and air conditioner

Abstract

Embodiments of the present application provide an injection molding part and an air conditioner. The injection molding part is an integrally injection molded part, which comprises a plate body and a reinforcing rib. The surface of one side of the plate body along the thickness direction is an appearance surface, and the surface of the other side is a non-appearance surface. The reinforcing rib is arranged on the non-appearance surface. The reinforcing rib comprises a plurality of annular ribs and a plurality of connecting ribs, and adjacent annular ribs are connected by connecting ribs. Since adjacent annular ribs are connected by connecting ribs, the occurrence of cross-shaped intersecting ribs in the reinforcing rib can be reduced to some extent, thereby improving the problem that the appearance surface of the injection molding part appears to shrink due to the too large thickness of the rib at the intersection position of the cross-shaped intersecting ribs, and thereby facilitating to balance the structural strength, the qualified rate and the aesthetics of the injection molding part. In addition, since the annular ribs are arranged, the density of the reinforcing rib can be relatively reduced under the condition that the reinforcing rib has the same reinforcing effect, thereby facilitating the ejection of the injection molding part and improving the production efficiency.

Description

Technical Field

[0001] This application relates to the field of injection molding technology, and in particular to an injection molded part and an air conditioner. Background Technology

[0002] As consumers demand higher quality products, key product components need to meet both functional and aesthetic requirements.

[0003] In related technologies, shrinkage marks are prone to appear on injection molded parts during injection molding. When severe shrinkage marks appear on the appearance of the product, it not only leads to a low product qualification rate and high cost, but also fails to meet the user's needs. Utility Model Content

[0004] In view of this, the embodiments of this application aim to provide an injection molded part and an air conditioner that can balance the structural strength, yield rate and aesthetics of the injection molded part.

[0005] The embodiments of this application are implemented through the following technical solutions.

[0006] A first aspect of this application provides an injection molded part, the injection molded part being an integrally injection molded part, the injection molded part comprising:

[0007] The plate body has a surface on one side along the thickness direction that is an external appearance surface and a surface on the other side that is not an external appearance surface;

[0008] Reinforcing ribs, wherein the reinforcing ribs are disposed on the non-surface surface.

[0009] The reinforcing ribs include multiple annular ribs and multiple connecting ribs, with adjacent annular ribs connected by the connecting ribs.

[0010] In some embodiments, at least a portion of the annular rib has an ejector position formed inside to mate with the ejector pin.

[0011] In some embodiments, the outline shape of the annular rib includes at least one of a circle, an ellipse, a polygon, or an irregular shape.

[0012] In some embodiments, the injection-molded part further includes sidewalls.

[0013] The sidewall is connected to the non-exterior surface of the plate, and some of the reinforcing ribs are connected to the sidewall.

[0014] In some embodiments, the annular reinforcement further includes a first annular reinforcement and a second annular reinforcement.

[0015] The first annular rib is spaced apart from the side wall, and the second annular rib is connected to the side wall.

[0016] In some embodiments, the outline shape of the second annular rib is the same as the outline shape of the first annular rib, and / or the outline shape of the second annular rib is the same as a partial outline shape of the first annular rib.

[0017] In some embodiments, at least some of the annular ribs are arranged along a first direction, and the spacing between the annular ribs arranged along the first direction is equal.

[0018] In some embodiments, the first end of the reinforcing rib is connected to the plate, and the second end of the reinforcing rib extends away from the plate.

[0019] The ratio of the thickness of the first end of the reinforcing rib to the thickness of the plate is in the range of 0.4 to 0.5.

[0020] In some embodiments, the equivalent diameter of the annular rib is in the range of 4 mm to 12 mm.

[0021] A second aspect of this application provides an air conditioner that includes the injection-molded part described above.

[0022] The injection molded part provided in this application embodiment has reinforcing ribs that include multiple annular ribs and multiple connecting ribs. By setting the annular ribs, the reinforcing effect of the ribs on the sheet body is enhanced, thereby improving the overall structural strength of the injection molded part. Since adjacent annular ribs are connected by connecting ribs, the occurrence of cross-shaped ribs in the reinforcing ribs can be reduced to a certain extent. This can improve the problem of shrinkage on the appearance surface of the injection molded part caused by excessive rib thickness at the intersection of cross-shaped ribs, thus helping to balance the structural strength, yield rate, and aesthetics of the injection molded part. Furthermore, due to the setting of annular ribs, the density of the reinforcing ribs can be relatively reduced while maintaining the same reinforcing effect, thereby facilitating the demolding of the injection molded part and improving production efficiency.

[0037] The following is a detailed description of this application.

[0038] As consumers demand higher quality products, key product components need to meet both functional and aesthetic requirements.

[0039] To achieve the required strength, injection molded parts often require the addition of reinforcing ribs in certain areas. In related technologies, these ribs are frequently arranged in a crisscross pattern, leading to excessive thickness at the intersections and potentially causing shrinkage in the product's appearance. To address this, related technologies typically involve thinning the cross-shaped ribs locally, but this affects the overall strength of the injection molded part. Furthermore, densely packed ribs can cause the product to stick to the mold, making demolding difficult. Research suggests that the reinforcing ribs can consist of multiple annular ribs and multiple connecting ribs. Since adjacent annular ribs are connected by connecting ribs, the occurrence of cross-shaped ribs can be reduced to some extent. This mitigates the shrinkage problem caused by excessive rib thickness at the intersections of cross-shaped ribs, thus helping to balance the structural strength, yield rate, and aesthetics of the injection molded part.

[0040] Based on this design concept, this application provides an air conditioner, which includes an injection-molded part 100 according to any embodiment of this application.

[0041] An air conditioner is a device used to regulate parameters such as indoor temperature, humidity, cleanliness, and airflow speed through functions such as cooling, heating, ventilation, and dehumidification.

[0042] The air conditioner adopts the injection molded part 100 of any embodiment of this application, which can take into account the structural strength, pass rate and aesthetics of the injection molded part 100 of the air conditioner.

[0043] For example, the injection molded part 100 may be an exterior part such as the housing of an air conditioner or a display component.

[0044] Of course, this structure can also be used for other injection-molded parts 100 of the air conditioner.

[0045] This application provides an injection molded part 100. Please refer to [link / reference]. Figures 1 to 3 The injection molded part 100 is an integrally injection molded part, including a plate 10 and reinforcing ribs 20. One surface of the plate 10 along its thickness direction is the visible surface 11, and the other surface is the non-visual surface 12. The reinforcing ribs 20 are disposed on the non-visual surface 12. The reinforcing ribs 20 include multiple annular ribs 21 and multiple connecting ribs 22, with adjacent annular ribs 21 connected by connecting ribs 22.

[0046] The injection molded part 100 of this application embodiment can be used for air conditioners, other household appliances, or other products including plastic parts other than household appliances.

[0047] It is understandable that the non-exterior surface 12 is not exposed on the outside of the air conditioner, while the exterior surface 11 is exposed on the outside of the air conditioner. During normal use of the air conditioner, the user cannot see the non-exterior surface 12, but can see the exterior surface 11.

[0048] Circular reinforcement 21 refers to reinforcement that is in the shape of a ring.

[0049] Adjacent annular ribs 21 are connected by connecting ribs 22. The annular ribs 21 have cavities inside, which reduces the possibility of the connecting ribs 22 intersecting to form cross ribs. In addition, it can enhance the reinforcing effect of the reinforcing ribs 20 on the plate 10.

[0050] The injection molded part 100 provided in this application embodiment includes multiple annular ribs 21 and multiple connecting ribs 22 in its reinforcing ribs 20. By setting the annular ribs 21, the reinforcing effect of the reinforcing ribs 20 on the plate 10 is enhanced, thereby improving the overall structural strength of the injection molded part 100. Since adjacent annular ribs 21 are connected by connecting ribs 22, the occurrence of cross-shaped ribs in the reinforcing ribs 20 can be reduced to a certain extent. This can improve the problem of shrinkage on the appearance surface 11 of the injection molded part 100 caused by excessive thickness of the ribs at the intersection of the cross-shaped ribs. This helps to balance the structural strength, yield rate, and aesthetics of the injection molded part 100. In addition, due to the setting of the annular ribs 21, the density of the reinforcing ribs 20 can be relatively reduced when the reinforcing ribs 20 have the same reinforcing effect, which is beneficial to the demolding of the injection molded part 100 and improves production efficiency.

[0051] In some embodiments, please refer to Figure 1 and Figure 2 At least part of the annular rib 21 has an ejector position 213 formed inside to cooperate with the ejector pin.

[0052] These locations are an important part of the mold design, used to eject the product from the mold using ejector pins after injection molding.

[0053] Ejector pins play a crucial role in injection molds. They are typically located at the bottom of the mold and are used to eject the injection-molded product.

[0054] The protruding position 213 may be formed inside part of the annular reinforcement 21, or the protruding position 213 may be formed inside all the annular reinforcement 21.

[0055] Because the annular rib 21 has a cavity inside, it can reduce the situation where the connecting ribs 22 cross each other to form a cross rib, and at the same time, it can form an ejection position 213 that cooperates with the ejector pin.

[0056] The ejector position 213 can be the cavity area inside the annular rib 21, or it can be a part of the cavity area inside the annular rib 21.

[0057] Since the area of ​​the injection molded part 100 with the annular rib 21 has good structural strength, by forming an ejection position 213 that cooperates with the ejector pin inside at least part of the annular rib 21, the ejector pin ejection force is better. At the same time, it can also improve the situation where the ejector pin forms an ejector pin mark on the injection molded part 100 when ejecting, and can avoid damage to the injection molded part 100 to a certain extent.

[0058] In some embodiments, the outline shape of the annular rib 21 includes at least one of a circle, an ellipse, a polygon, or an irregular shape.

[0059] In other words, the cross-sectional shape of the annular rib 21 includes at least one of the following: circular, elliptical, polygonal, or irregular.

[0060] Here, the outline shape of the annular rib 21 includes one or more of the following: circle, ellipse, polygon, or irregular shape.

[0061] Here, the outline shape of the annular rib 21 can be adapted to the shape of the ejector pin so that an ejector position 213 is formed inside the annular rib 21. For example, the outline shape of the annular rib 21 is circular so as to cooperate with a circular ejector pin.

[0062] Of course, the shape of the annular reinforcement 21 can also be matched with the distribution of the connecting reinforcement 22 to facilitate the connection between the annular reinforcement 21 and the connecting reinforcement 22.

[0063] In some embodiments, please refer to Figures 1 to 2 The injection molded part 100 also includes a side wall 30, which is connected to the non-visual surface 12 of the plate 10, and some reinforcing ribs 20 are connected to the side wall 30.

[0064] Here, the sidewall 30 can be connected to the middle region of the plate 10, the side of the plate 10, or the edge region of the plate 10.

[0065] One end of the side of the plate 10 along the thickness direction is connected to the appearance surface 11, and the other end along the thickness direction is connected to the non-appearance surface 12.

[0066] For example, the sidewall 30 surrounds the periphery of the reinforcing rib 20, that is, the sidewall 30 is connected to the edge area of ​​the reinforcing rib 20.

[0067] The connection between the annular reinforcement 21 and the side wall 30 can be either the connection between the connecting reinforcement 22 and the side wall 30, or a combination of both.

[0068] Since some of the reinforcing ribs 20 are connected to the side wall 30, the reinforcing ribs 20 and the side wall 30 can be connected into a whole. This helps to improve the reinforcing effect of the reinforcing ribs 20, thereby further improving the overall structural strength of the injection molded part 100.

[0069] In some embodiments, please refer to Figure 1 The annular rib 21 also includes a first annular rib 211 and a second annular rib 212. The first annular rib 211 is spaced apart from the side wall 30, and the second annular rib 212 is connected to the side wall 30.

[0070] For example, the first annular rib 211 is located inside the reinforcing rib 20, thus being spaced apart from the side wall 30, and the second annular rib 212 is located at the edge of the reinforcing rib 20, thus being connected to the side wall 30.

[0071] Since the second annular rib 212 is connected to the side wall 30, it helps to improve the reinforcing effect of the reinforcing rib 20, thereby further improving the overall structural strength of the injection molded part 100.

[0072] In some embodiments, please refer to Figures 1 to 2 The outline shape of the second annular rib 212 is the same as the outline shape of the first annular rib 211, and / or the outline shape of the second annular rib 212 is the same as the partial outline shape of the first annular rib 211.

[0073] The outline shape of the second annular rib 212 is the same as that of the first annular rib 211, that is, the interior of the second annular rib 212 is enclosed to form a closed cavity.

[0074] The outline shape of the second annular rib 212 is the same as the partial outline shape of the first annular rib 211. That is to say, the second annular rib 212 and the side wall 30 together form a closed cavity.

[0075] It should be noted that the arrangement of the ring reinforcement 21 is not restricted here.

[0076] For example, the annular ribs 21 are formed in a uniformly distributed manner on the plate 10.

[0077] It should be noted that the annular ribs 21 are "uniformly distributed," meaning that the individual annular ribs 21 are distributed in a matrix or concentric circles. In other words, the arrangement of each annular rib 21 is uniform. It is understandable that the individual annular ribs 21 may not be uniform within the cross-section of the plate 10. That is, although the individual annular ribs 21 are uniformly distributed, they do not uniformly divide the entire plate 10.

[0078] In some embodiments, please refer to Figures 1 to 2At least some of the annular ribs 21 are arranged along the first direction, and the spacing between the annular ribs 21 arranged along the first direction is equal.

[0079] In other words, at least some of the annular ribs 21 are evenly distributed along the first direction.

[0080] For example, please refer to Figure 1 and Figure 2 The first direction is denoted by Z1, and the second direction is denoted by Z2.

[0081] For example, all the annular ribs 21 are distributed on multiple trajectory lines, wherein each annular rib 21 on a single trajectory line is linearly arranged along a first direction Z1, and multiple trajectory lines are linearly arranged along a second direction Z2. The first direction Z1 and the second direction Z2 are not parallel, that is, the multiple air channels are not arranged in a straight line.

[0082] For example, the first direction Z1 and the second direction Z2 are perpendicular to each other.

[0083] In some embodiments, please refer to Figures 1 to 3 The first end of the reinforcing rib 20 is connected to the plate 10, and the second end of the reinforcing rib 20 extends away from the plate 10. The ratio of the thickness of the first end of the reinforcing rib 20 to the thickness of the plate 10 is in the range of 0.4 to 0.5.

[0084] For example, the thickness of the reinforcing rib 20 gradually decreases along the direction from the first end to the second end, which facilitates the demolding of the reinforcing rib 20.

[0085] For example, if the thickness of the plate 10 is H and the thickness of the first end of the reinforcing rib 20 is T, then T is between 0.4H and 0.5H.

[0086] Since the ratio of the thickness of the first end of the reinforcing rib 20 to the thickness of the plate 10 is in the range of 0.4 to 0.5, the thickness within this range is appropriate. On the one hand, the reinforcing rib 20 can have a certain structural strength, thus having a certain strengthening effect and facilitating demolding. On the other hand, it can, to a certain extent, avoid the shrinkage of the appearance surface 11 of the plate 10 caused by the excessive thickness of the first end of the reinforcing rib 20.

[0087] In some embodiments, please refer to Figures 1 to 2 The equivalent diameter of the ring rib 21 is in the range of 4mm to 12mm.

[0088] The equivalent diameter is the diameter calculated by equating an irregular object to a sphere or circle with the same specific properties.

[0089] The equivalent diameter of the ring rib 21 can be 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm, 10.5mm, 11mm, 11.5mm, 12mm, etc.

[0090] By setting the equivalent diameter of the annular rib 21 in the range of 4mm to 12mm, on the one hand, the reinforcing rib 20 can have a certain structural strength, thus having a certain reinforcing effect and facilitating demolding; on the other hand, it can facilitate the formation of an ejector position 213 inside the annular rib 21 that cooperates with the ejector pin.

[0091] In the description of this application, the references to terms such as "in one embodiment," "in some embodiments," "in other embodiments," "in yet another embodiment," or "exemplary," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the embodiments of this application.
