Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to an air conditioner panel, a mold for manufacturing the air conditioner panel, and an air conditioner. Background Art

[0002] An air conditioner has functions such as adjusting the indoor temperature and improving the indoor air quality, and has now become an indispensable electrical appliance in households. An air conditioner generally has an indoor unit and an outdoor unit. Among them, in order to enable users to more intuitively see the current operating condition of the air conditioner, a display window is usually provided on the air conditioner indoor unit, and information such as temperature is displayed by digital display or the like. Currently, it has become a market trend to combine the air conditioner display window and the front panel of the air conditioner, which can simplify the product appearance, reduce both the number of product parts and the manufacturing cost. However, the overall wall thickness of the air conditioner panel is locally thinned for light transmission display, and the poor plastic flow caused by the wall thickness difference will lead to defects such as air entrapment, weld lines, and deformation on the product surface, which limits the wall thickness of the display window position and affects the display effect. Summary of the Utility Model

[0003] The purpose of this application is to provide an air conditioner panel, a mold for manufacturing the air conditioner panel, and an air conditioner, so that the air conditioner panel can be better formed and the wall thickness of the display window can be optimized.

[0004] The purpose of this application is achieved through the following technical solutions:

[0005] An air conditioner panel, comprising:

[0006] A panel main body, the panel main body has a first plate body, a first transition area, a second plate body, a first transition area, and a first plate body connected in sequence along its length direction, a second transition area is provided on the second plate body, the thickness of the first plate body is greater than the thickness of the second plate body, an installation hole penetrating through the front and back is provided on the second transition area, the thickness of the first transition area gradually decreases from the first plate body to the second plate body, and the thickness of the second transition area gradually decreases from the second plate body to the installation hole; and

[0007] A display window, the display window is embedded in the installation hole, and the thickness of the display window is less than the thickness of the second plate body;

[0008] Wherein, the thickness of the first plate body is D1, the thickness of the second plate body is D2, the thickness of the display window is D3, and D1, D2, D3 satisfy the following relationship: 2.5:1.6:1 < D1:D2:D3 < 2.5:2:1.

[0009] Beneficial effects: The air conditioner panel has a structure with a display window. Users can see the air conditioner status display part behind the air conditioner panel through the display window, which is convenient for users to understand the real-time situation of the air conditioner. For clear display, the thickness of the display window is relatively thin, and there is a certain gap in the wall thickness between the panel body and the display window. Therefore, the wall thickness of the panel body can gradually decrease towards the mounting hole of the display window in a multi-stage transition manner. This can avoid sudden changes in the wall thickness between the panel body and the display window and prevent defects such as incomplete filling, gas entrapment, weld lines, and stress marks during the molding process. At the same time, the multi-stage transition method is more suitable for situations with a large wall thickness difference, enabling each position of the panel body to be molded perfectly; moreover, the thicknesses of the first plate body, the second plate body, and the display window satisfy 2.5:1.6:1 < D1:D2:D3 < 2.5:2:1. This can not only avoid excessive wall thickness difference between the panel body and the display window, which may still cause injection molding defects even with a transition method, but also prevent the problem of too low strength of the air conditioner panel due to too small a thickness of the panel body, taking into account both the yield rate and reliability of the air conditioner panel.

[0010] In some embodiments of the present application, the thickness D1 of the first plate body is 2 mm to 3 mm, the thickness D2 of the second plate body is 1.6 mm to 2 mm, and the thickness D3 of the display window is 0.8 mm to 1.2 mm.

[0011] Beneficial effects: For a conventional air conditioner panel, as the thickest part, the thickness D1 of the first plate body is between 2 mm and 3 mm, which can ensure the strength of the air conditioner panel. The thickness D3 of the display window is between 0.8 mm and 1.2 mm, which can make the display clearer, and the power of the display light source at the back of the air conditioner panel can be lower. At the same time, it will not cause problems of easy damage due to too thin a wall thickness, taking into account both energy conservation and stability. The second plate body is located between the first plate body and the display window and is connected to them through the first transition area and the second transition area respectively. Therefore, the thickness of the second plate body should be between the first plate body and the display window and preferably at the median of their thicknesses to ensure a smooth transition of the two transition areas, prevent the thickness difference from being too large, and improve the stability and reliability of the air conditioner panel.

[0012] In some embodiments of the present application, the length L of the first transition area in the length direction of the panel body is at least 60 mm.

[0013] Beneficial effects: The first plate body needs to be smoothly transitioned to the second plate body through the first transition area. To avoid a sudden change in thickness between the first plate body and the second plate body due to too large an inclination of the first transition area, the length of the first transition area needs to be at least 60 mm. Such a size can ensure a smooth transition of the thickness for most air conditioners, further ensuring the molding performance of the air conditioner panel.

[0014] In some embodiments of the present application, it further includes flanges. The flanges are provided on both side edges in the length direction and the width direction of the panel body, and the flanges extend towards the rear side of the panel body.

[0015] Beneficial effects: On the one hand, the flange structure can increase the strength of the air conditioner panel. In the case where the air conditioner panel adopts a large flat injection-molded plate structure, setting the flanges at the edge positions of the panel body can effectively improve the anti-torsion performance and bending performance of the panel body. On the other hand, the flange structure can facilitate the installation of the air conditioner panel. By inserting the flanges into other structures of the air conditioner indoor unit at the rear side of the air conditioner panel, the purpose of snap connection can be achieved. At the same time, the flange part is hollowed out, and the main body of the indoor unit and the hollowed-out part of the flange are locked by means of fasteners, etc., so that the installation of the air conditioner panel and the main body of the indoor unit can be simply and conveniently realized.

[0016] In some embodiments of the present application, the air conditioner panel is of a rectangular structure, the display window is located in the middle of the panel body, and the second transition region extends around the edge of the display window.

[0017] Beneficial effects: The air conditioner panel is of a rectangular plate structure, which has good adaptability and can meet the installation requirements of most air conditioners. The display window is located in the middle of the panel body, and the rest gradually transitions towards the middle and is symmetrically arranged in the length direction of the panel body, making the overall structural layout more reasonable, the stress of each part more balanced, and the molding easier. During the use of the air conditioner, users do not need to know many operating parameters, and only need to know key operating parameters such as temperature and wind speed. Therefore, the size of the display window should not be too large to ensure the reliability of the air conditioner panel. On this basis, the second transition region can select an appropriate extension length according to the thickness difference between the second plate body and the display window and extend around the edge position of the display window.

[0018] A mold for manufacturing the air conditioner panel as described above includes:

[0019] A mold body, the interior of the mold body defines a cavity for molding the air conditioner panel; and

[0020] A glue inlet nozzle, the bottom of the glue inlet nozzle is communicated with the cavity for introducing the material for forming the air conditioner panel into the cavity;

[0021] Among them, the glue inlet nozzle includes a first glue inlet nozzle, a second glue inlet nozzle, and a third glue inlet nozzle. The first glue inlet nozzle, the second glue inlet nozzle, and the third glue inlet nozzle are all located at the top of the cavity. The cavity includes a first cavity for forming the first plate body, a second cavity for forming the first transition area, a third cavity for forming the second plate body, a fourth cavity for forming the second transition area, and a fifth cavity for forming the display window. The first glue inlet nozzle is arranged at the first cavity, the second glue inlet nozzle is arranged at the second cavity, and the third glue inlet nozzle is arranged near the fifth cavity and is respectively arranged at the front side and the rear side of the fifth cavity.

[0022] Advantageous effects: The air-conditioning panel is formed by mold injection molding. To ensure the yield of the air-conditioning panel, the arrangement of the nozzles on the mold is crucial. Among them, the glue inlet nozzle is generally divided into three parts. The first glue inlet nozzle is located above the first cavity, and the first cavity corresponds to the first plate body part of the air-conditioning panel and is used for injecting plastic into the first cavity. The second glue inlet nozzle is located above the second cavity, and the second cavity corresponds to the first transition area part of the air-conditioning panel and is used for injecting plastic into the first cavity, the second cavity, and the third cavity. The third glue inlet nozzle corresponds to the second transition area part of the air-conditioning panel and is used for injecting plastic into the third cavity, the fourth cavity, and the fifth cavity. The plastic entering the cavity through the glue inlet nozzle flows in the cavity, thereby filling the cavity. The layout of each part of the glue inlet nozzle is reasonable, which can ensure the yield of the air-conditioning panel and reduce defects such as air entrapment, weld lines, and deformation on the product surface.

[0023] In some embodiments of the present application, the distance between the third glue inlet nozzle located at the front side and the front end of the fifth cavity is 20 mm to 30 mm, and the distance between the third glue inlet nozzle located at the rear side and the rear end of the fifth cavity is 20 mm to 30 mm.

[0024] Advantageous effects: The glue inlet nozzle has a cooling sleeve with a diameter of 20 mm. If the glue inlet position of the glue inlet nozzle is less than 20 mm away from the fifth cavity, the parting line of the cooling sleeve will affect the forming of the display window, resulting in a poor display effect of the display window; if the glue inlet position is too far from the fifth cavity, greater than 30 mm, the filling resistance of the fifth cavity will become very large, resulting in its inability to be filled, and air entrapment defects will form at the display window position. Therefore, the distance between the third glue inlet nozzle and the fifth cavity is preferably in the range of 20 mm to 30 mm.

[0025] In some embodiments of the present application, the center point of the third glue inlet nozzle is located on the center line in the horizontal direction of the fifth cavity.

[0026] Beneficial effects: The third glue inlet nozzle is located at the middle position in the horizontal direction. Since the cavities on both sides of the third glue inlet nozzle are symmetrically arranged, it can ensure that the plastic entering the cavity from the third glue inlet nozzle can be evenly filled to the left and right sides of the third glue inlet nozzle, ensuring the filling balance on both sides of the third glue inlet nozzle.

[0027] In some embodiments of the present application, the mold body has a mold block located at the top of the cavity. The mold block is provided with a cut-off portion close to one side of the cavity and extending towards the bottom of the mold body. The cut-off portion is located on the left and right sides of the third glue inlet nozzle and is used to form a cut-off area at the corresponding position of the panel body. The thickness of the cut-off portion is 0.1 mm to 0.7 mm.

[0028] Beneficial effects: The top of the cavity is defined by the mold block. The cut-off portion provided on the mold block is a downward protruding structure compared to other smoothly transitioning parts. This part is arranged on the left and right sides of the third glue inlet nozzle, which makes the plastic filled by the third glue inlet nozzle flow towards the position of the fifth cavity as much as possible when filling the plastic, reducing the amount of plastic filled to the left and right sides of the third glue inlet nozzle. In this way, the thinner fifth cavity can be filled more easily. Otherwise, due to resistance problems, a large amount of plastic will flow towards the third cavity during the plastic flow, resulting in the fifth cavity not being filled; in addition, the thickness of the cut-off portion is between 0.1 mm and 0.7 mm, so the thickness of the cut-off area of the air conditioner panel is 1.1 mm to 1.7 mm. This thickness is between the thickness of the second plate body and the thickness of the display window, which can effectively achieve the purpose of cut-off.

[0029] An air conditioner, comprising:

[0030] An air conditioner indoor unit for heat exchange with indoor air. The air conditioner indoor unit has an indoor unit main body and the above-mentioned air conditioner panel, and the air conditioner panel covers the front end of the indoor unit main body; and

[0031] An air conditioner outdoor unit for heat exchange with outdoor air. The air conditioner outdoor unit is connected to the indoor unit main body.

[0032] Beneficial effects: The air conditioner includes an air conditioner indoor unit and an air conditioner outdoor unit. The air conditioner indoor unit is used for heat exchange with indoor air, and the air conditioner outdoor unit is used for heat exchange with outdoor air, so as to adjust the indoor temperature to a suitable temperature. The front end of the air conditioner indoor unit is installed with an air conditioner panel. The air conditioner panel is formed by a uniform multi-stage transition method for each part, which not only has a good forming effect but also does not affect the normal use of the air conditioner. At the same time, when observing the air conditioner panel from the outside, it is a whole smooth transition board, and after opening, it can display the air conditioner operation parameters at the display window position, ensuring both practicality and aesthetics.

[0033] The beneficial effects of the present application are as follows: The air-conditioning panel has a structure with a display window. Users can see the air-conditioning status display part behind the air-conditioning panel through the display window, which is convenient for users to understand the real-time situation of the air conditioner. For clear display, the thickness of the display window is relatively thin, and there is a certain gap in the wall thickness between the panel body and the display window. Therefore, the wall thickness of the panel body can be gradually reduced in a multi-stage transition manner towards the mounting hole of the display window, so as to avoid sudden changes in the wall thickness between the panel body and the display window and prevent defects such as incomplete filling, air entrapment, weld lines, and stress marks during the molding process. At the same time, the multi-stage transition method is also more suitable for the case of a large wall thickness difference, enabling each position of the panel body to be molded perfectly; moreover, the thicknesses of the first plate body, the second plate body, and the display window need to be within the specified range, which can not only avoid too large a wall thickness difference between the panel body and the display window, resulting in injection molding defects even with the transition method, but also prevent the problem of too low strength of the air-conditioning panel caused by too small a wall thickness of the panel body, taking into account both the yield rate and reliability of the air-conditioning panel.

Specific Embodiment

[0045] The following combines the accompanying drawings and embodiments to further describe in detail the specific embodiments of the present utility model. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0046] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0047] The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise stated, the meaning of "a plurality" is two or more.

[0048] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0049] In this application, the air conditioner performs the refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes, involving compression, condensation, expansion, and evaporation, and supplying refrigerant to the air that has been conditioned and heat-exchanged.

[0050] The compressor compresses the refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0051] The expansion valve expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by exchanging heat with the material to be cooled by utilizing the latent heat of evaporation of the refrigerant. Throughout the cycle, the air conditioner can adjust the temperature of the indoor space.

[0052] The outdoor unit of the air conditioner refers to the part of the refrigeration cycle including the compressor and the outdoor heat exchanger. The indoor unit of the air conditioner includes the indoor heat exchanger, and the expansion valve can be provided in the indoor unit or the outdoor unit.

[0053] The indoor heat exchanger and the outdoor heat exchanger serve as condensers or evaporators. When the indoor heat exchanger serves as a condenser, the air conditioner serves as a heater in the heating mode. When the indoor heat exchanger serves as an evaporator, the air conditioner serves as a cooler in the cooling mode.

[0054] Based on the above structure, as Figures 1 - 4 shown, a first aspect of the present application proposes an air-conditioning panel 100, including: a panel main body 1 and a display window 2. The panel main body 1 has a first plate body 11, a first transition area 12, a second plate body 13, a first transition area 12, and a first plate body 11 connected in sequence along its length direction. A second transition area 14 is provided on the second plate body 13. The thickness of the first plate body 11 is greater than the thickness of the second plate body 13. An installation hole 15 penetrating through the front and back is provided on the second transition area 14. The thickness of the first transition area 12 gradually decreases from the first plate body 11 to the second plate body 13. The thickness of the second transition area 14 gradually decreases from the second plate body 13 to the installation hole 15. The display window 2 is embedded in the installation hole 15, and the thickness of the display window 2 is less than the thickness of the second plate body 13. Wherein, the thickness of the first plate body 11 is D1, the thickness of the second plate body 13 is D2, and the thickness of the display window 2 is D3. D1, D2, and D3 satisfy the following relationship: 2.5:1.6:1 < D1:D2:D3 < 2.5:2:1.

[0055] Based on the above technical solution, the air conditioner panel 100 has a structure with a display window 2. Users can see the air conditioner status display part behind the air conditioner panel 100 through the display window 2, which is convenient for users to understand the real-time situation of the air conditioner. For clear display, the thickness of the display window 2 is relatively thin, and there is a certain gap between the wall thickness of the panel body 1 and the display window 2. Therefore, the wall thickness of the panel body 1 can be gradually reduced in a multi-stage transition manner towards the mounting hole 15 of the display window 2. In this way, the sudden change in the wall thickness between the panel body 1 and the display window 2 can be avoided, and defects such as incomplete filling, gas entrapment, weld line, and stress mark during the molding process can be avoided. At the same time, the multi-stage transition method is also more beneficial for the situation with a large wall thickness difference, enabling each position of the panel body 1 to be molded perfectly; moreover, the thicknesses of the first plate body 11, the second plate body 13, and the display window 2 need to be within a specified range. This can not only avoid too large a wall thickness difference between the panel body 1 and the display window 2, resulting in injection molding defects even with the transition method, but also avoid the problem of too low strength of the air conditioner panel 100 caused by too small a thickness of the panel body 1, taking into account both the yield rate and reliability of the air conditioner panel 100.

[0056] In some embodiments of the present application, as Figure 3 shown, the thickness D1 of the first plate body 11 is 2 mm to 3 mm, the thickness D2 of the second plate body 13 is 1.6 mm to 2 mm, and the thickness D3 of the display window 2 is 0.8 mm to 1.2 mm. For a conventional air conditioner panel 100, as the part with the largest thickness, the thickness D1 of the first plate body 11 being between 2 mm and 3 mm can ensure the strength of the air conditioner panel 100, while the thickness D3 of the display window 2 being between 0.8 mm and 1.2 mm can make the display clearer, the power of the display light source behind the air conditioner panel 100 can be lower, and at the same time, the problem of easy damage due to too thin a wall thickness can be avoided, taking into account both energy conservation and stability. The second plate body 13 is located between the first plate body 11 and the display window 2 and is connected to them through the first transition area 12 and the second transition area 14 respectively. Therefore, the thickness of the second plate body 13 should be between the first plate body 11 and the display window 2 and preferably be at the median of their thicknesses to ensure a smooth transition of the two transition areas, so that the thickness difference is not too large, improving the stability and reliability of the air conditioner panel 100. Preferably, the thickness D1 of the first plate body 11 is 2.5 mm, the thickness D2 of the second plate body 13 is 1.8 mm, and the thickness D3 of the display window 2 is 1 mm. Such a thickness design can better balance the display performance and stability performance.

[0057] In some embodiments of the present application, as Figure 3As shown in the figure, the length L of the first transition region 12 in the length direction of the panel body 1 is at least 60 mm. The first plate body 11 and the second plate body 13 need to be smoothly transitioned through the first transition region 12. In order to avoid a large slope of the first transition region 12 resulting in a thickness mutation between the first plate body 11 and the second plate body 13, the length of the first transition region 12 needs to be at least 60 mm. Such a size can ensure a smooth transition of the thickness for most air conditioners, further ensuring the forming performance of the air conditioner panel 100.

[0058] In some embodiments of the present application, as Figures 1 - 3 shown in the figure, it further includes a flanging 3. The flanging 3 is provided on both side edges of the panel body 1 in the length direction and the width direction, and the flanging 3 extends towards the rear side of the panel body 1. On the one hand, the flanging 3 structure can increase the strength of the air conditioner panel 100. In the case where the air conditioner panel 100 adopts a large flat injection-molded plate structure, setting the flanging 3 at the edge position of the panel body 1 can effectively improve the torsional resistance and bending performance of the panel body 1. On the other hand, the flanging 3 structure can facilitate the installation of the air conditioner panel 100. By inserting the flanging 3 into other structures of the air conditioner indoor unit at the rear side of the air conditioner panel 100, the purpose of clamping can be achieved. At the same time, the flanging 3 is partially hollowed out, and the indoor unit body and the hollowed-out part of the flanging 3 can be locked through fasteners and other means, which can simply and conveniently realize the installation of the air conditioner panel 100 and the indoor unit body. It should be noted that the flanging 3 in the length direction of the air conditioner panel 100 can be synchronously transitioned according to the thickness of each part in the length direction to balance the stability performance and forming performance of the flanging 3.

[0059] In some embodiments of the present application, as Figures 1 - 4 shown in the figure, the air conditioner panel 100 is of a rectangular structure, the display window 2 is located in the middle of the panel body 1, and the second transition region 14 extends around the edge of the display window 2. The air conditioner panel 100 is of a rectangular plate structure, which has good adaptability and can meet the installation requirements of most air conditioners. The display window 2 is located in the middle of the panel body 1, and the rest gradually transitions towards the middle and is symmetrically arranged in the length direction of the panel body 1, making the overall structural layout more reasonable, the stress of each part more balanced, and the forming easier. During the use of the air conditioner, users only need to know key operating parameters such as temperature and wind speed, so the size of the display window 2 should not be too large to ensure the reliability of the air conditioner panel 100. On this basis, the second transition region 14 can select an appropriate extension length according to the thickness difference between the second plate body 13 and the display window 2 and extend around the edge position of the display window 2.

[0060] As Figures 5 - 10As shown in the figure, the second aspect of the present application provides a mold for manufacturing the air conditioner panel 100 as described above, including: a mold body 4 and a feed nozzle 5. An internal cavity 41 for molding the air conditioner panel 100 is defined inside the mold body 4. The bottom of the feed nozzle 5 is communicated with the cavity 41 for introducing the material for forming the air conditioner panel 100 into the cavity 41. Among them, the feed nozzle 5 includes a first feed nozzle 51, a second feed nozzle 52, and a third feed nozzle 53. The first feed nozzle 51, the second feed nozzle 52, and the third feed nozzle 53 are all located at the top of the cavity 41. The cavity 41 includes a first cavity 411 for molding the first plate body 11, a second cavity 412 for molding the first transition area 12, a third cavity 413 for molding the second plate body 13, a fourth cavity 414 for molding the second transition area 14, and a fifth cavity 415 for molding the display window 2. The first feed nozzle 51 is arranged at the position of the first cavity 411, the second feed nozzle 52 is arranged at the position of the second cavity 412, and the third feed nozzle 53 is arranged close to the fifth cavity 415 and is respectively arranged at the front side and the rear side of the fifth cavity 415.

[0061] Based on the above technical solution, the air conditioner panel 100 is molded by the injection molding method of the mold. In order to ensure the yield of the air conditioner panel 100, the arrangement of the nozzles on the mold plays a crucial role. Among them, the feed nozzle 5 is generally divided into three parts. The first feed nozzle 51 is located above the first cavity 411. The first cavity 411 corresponds to the first plate body 11 part of the air conditioner panel 100 and is used for injecting plastic into the first cavity 411. The second feed nozzle 52 is located above the second cavity 412. The second cavity 412 corresponds to the first transition area 12 part of the air conditioner panel 100 and is used for injecting plastic into the first cavity 411, the second cavity 412, and the third cavity 413. The third feed nozzle 53 corresponds to the second transition area 14 part of the air conditioner panel 100 and is used for injecting plastic into the third cavity 413, the fourth cavity 414, and the fifth cavity 415. The plastic entering the cavity 41 through the feed nozzle 5 flows in the cavity 41, thereby filling the cavity 41. The layout of each part of the feed nozzle is reasonable, which can ensure the yield of the air conditioner panel 100 and reduce defects such as air entrapment, weld lines, and deformation on the product surface. In addition, according to the actual product structure characteristics of the air conditioner panel 100, if there are rib positions or other structures on the side of the air conditioner panel 100, then one or more feed nozzles need to be placed at the parting surface position for pressure holding of the side wall to avoid shrinkage marks and enable the air conditioner panel 100 to be successfully molded.

[0062] In some embodiments of the present application, such as Figure 5 , Figure 6 , Figure 8As shown, the distance between the front third glue inlet nozzle 53 and the front end of the fifth cavity 415 is 20 mm to 30 mm, and the distance between the rear third glue inlet nozzle 53 and the rear end of the fifth cavity 415 is 20 mm to 30 mm. The glue inlet nozzle has a cooling sleeve with a diameter of 20 mm. If the glue inlet position of the glue inlet nozzle is less than 20 mm away from the fifth cavity 415, the parting line of the cooling sleeve will affect the molding of the display window 2, resulting in a poor display effect of the display window 2; if the glue inlet position is too far from the fifth cavity 415, greater than 30 mm, then the filling resistance of the fifth cavity 415 will become very large, resulting in its inability to be filled, and air entrapment defects will form at the position of the display window 2. Therefore, the distance between the third glue inlet nozzle 53 and the fifth cavity 415 is preferably 20 mm to 30 mm. It should be noted that the above-mentioned glue inlet position is located at the center position of the glue inlet nozzle, which can ensure the smooth discharge of the material; preferably, the distance between the third glue inlet nozzle 53 and the fifth cavity 415 is 25 mm, which makes the display window 2 easier to mold and avoids the interference of the third glue inlet nozzle 53.

[0063] In some embodiments of the present application, as Figure 5 , Figure 6 and Figures 8 - 10 shown, the center point of the third glue inlet nozzle 53 is located on the center line of the fifth cavity 415 in the horizontal direction. The third glue inlet nozzle 53 is located at the middle position in the horizontal direction. Since the cavities 41 on both sides of the third glue inlet nozzle 53 are symmetrically arranged, it can ensure that the plastic entering the cavity 41 from the third glue inlet nozzle 53 can be evenly filled to the left and right sides of the third glue inlet nozzle 53, ensuring the filling balance on both sides of the third glue inlet nozzle 53.

[0064] Specifically, as Figure 1 , Figure 2 , Figure 9 , Figure 10As shown, the mold body 4 has a mold block 42 located at the top of the cavity 41. The mold block 42 is provided with a current intercepting portion 421 that is close to one side of the cavity 41 and extends towards the bottom of the mold body 4. The current intercepting portion 421 is located on the left and right sides of the third gate 53 and is used to form a current intercepting area 16 at the corresponding position of the panel body 1. The thickness of the current intercepting portion 421 is 0.1 mm to 0.7 mm. The top of the cavity 41 is defined by the mold block 42. The current intercepting portion 421 provided on the mold block 42 is a downward protruding structure compared to other smoothly transitioning parts. This part is provided on the left and right sides of the third gate 53, which enables the third gate 53 to flow the plastic towards the position of the fifth cavity 415 as much as possible when filling the plastic, reducing the amount of plastic filled to the left and right sides of the third gate 53. In this way, the thinner fifth cavity 415 can be more easily filled. Otherwise, due to resistance problems, a large amount of plastic will flow towards the third cavity 413 during the plastic flow, resulting in the fifth cavity 415 not being filled; in addition, the thickness of the current intercepting portion 421 is between 0.1 mm and 0.7 mm, so the thickness of the current intercepting area 16 of the air conditioner panel 100 is 1.1 mm to 1.7 mm. This thickness is between the thickness of the second plate body 13 and the thickness of the display window 2, which can effectively achieve the purpose of current interception. Preferably, the thickness of the current intercepting portion 421 is 0.4 mm, that is, the thickness of the current intercepting area 16 of the air conditioner panel 100 is 1.4 mm. The current intercepting portion 421 with this thickness can balance the forming performance of the third cavity 413 and the fifth cavity 415, making the finally formed air conditioner panel 100 have fewer defects and a higher yield rate.

[0065] In a third aspect of the present application, an air conditioner is proposed, including: an air conditioner indoor unit and an air conditioner outdoor unit. The air conditioner indoor unit is used for heat exchange with indoor air. The air conditioner indoor unit has an indoor unit main body and the air conditioner panel 100 as described above. The air conditioner panel 100 is covered on the front end of the indoor unit main body. The air conditioner outdoor unit is used for heat exchange with outdoor air. The air conditioner outdoor unit is connected to the indoor unit main body. The air conditioner includes an air conditioner indoor unit and an air conditioner outdoor unit. The air conditioner indoor unit is used for heat exchange with indoor air, and the air conditioner outdoor unit is used for heat exchange with outdoor air, so as to adjust the indoor temperature to a suitable temperature. The air conditioner panel 100 is installed at the front end of the air conditioner indoor unit. The air conditioner panel 100 is formed by using a uniform multi-stage transition method for each part, which not only has a good forming effect but also does not affect the normal use of the air conditioner. At the same time, when observing the air conditioner panel 100 from the outside, it is a whole plate with a smooth transition. After being opened, the air conditioner operation parameters can be displayed at the position of the display window 2, which not only ensures the practicability but also takes into account the aesthetics.

[0066] In summary, for the air conditioner panel 100 of the present application, the mold for manufacturing the air conditioner panel 100, and the air conditioner, the air conditioner panel 100 has a structure with a display window 2. Users can see the air conditioner status display part behind the air conditioner panel 100 through the display window 2, which is convenient for users to understand the real-time situation of the air conditioner. For clear display, the thickness of the display window 2 is relatively thin, and there is a certain gap in the wall thickness between the panel main body 1 and the display window 2. Therefore, the wall thickness of the panel main body 1 can be gradually reduced in a multi-stage transition manner towards the mounting hole 15 of the display window 2. In this way, the sudden change in the wall thickness between the panel main body 1 and the display window 2 can be avoided, and defects such as incomplete filling, gas entrapment, weld line, and stress mark during the molding process can be avoided. At the same time, the multi-stage transition method is also more beneficial for the case where the wall thickness difference is large, enabling each position of the panel main body 1 to be molded perfectly; moreover, the thicknesses of the first plate body 11, the second plate body 13, and the display window 2 need to be within a specified range. This can not only avoid the problem that the wall thickness difference between the panel main body 1 and the display window 2 is too large, resulting in injection molding defects even with the transition method, but also avoid the problem that the strength of the air conditioner panel 100 is too low due to the too small thickness of the panel main body 1, taking into account the yield and reliability of the air conditioner panel 100.

[0067] The above is only the preferred embodiment of the present application. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present application, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present application.
