Abstract
Description
Technical Field
[0001] This application relates to the field of injection molding technology, and in particular to an injection mold and an injection molding device. Background Technology
[0002] The application of injection molding is becoming increasingly common. For example, an air conditioner indoor unit includes a frame with a grille. The frame is formed using an injection mold. The injection mold needs to be designed with a slider for ejection at the grille location. The slider of the injection mold interacts with the inner mold, and the contact surface between the slider and the inner mold is also the sealing surface. The sealing surface and the glue-forming surface at the grille location on the inner mold are coplanar. The glue-forming surface needs to be polished to facilitate frame demolding and meet gloss requirements, while the sealing surface does not need polishing to avoid over-cutting. However, in related technologies, during the manual polishing of the glue-forming surface of the inner mold, the sealing surface is easily polished, leading to over-cutting of the sealing surface. Utility Model Content
[0003] This application provides an injection mold and an injection device, wherein at least a portion of the transition surface and the glue surface are not in the same plane, which makes it easy for operators to visually distinguish the second sealing surface and the glue surface, and can avoid the problem of overcutting caused by polishing the second sealing surface to a certain extent.
[0004] The technical solution of this application embodiment is implemented as follows:
[0005] This application provides an injection mold, including:
[0006] A first slider, the first slider including a first sealing surface;
[0007] The inner mold includes a second sealing surface, a glue-positioning surface, and a transition surface.

The glue-positioning surface and the transition surface are both part of the cavity wall surface. The second sealing surface and the glue-positioning surface are located in the same plane. At least a portion of the transition surface and the glue-positioning surface are not in the same plane.
[0008] In some embodiments, both the second sealing surface and the adhesive surface are located on the first plane, and at least a portion of the transition surface is located on the second plane, which intersects with the first plane.

[0010] In some embodiments, the distance between the first end and the second end in the second direction is L1, where 1mm≤L1≤2mm.
[0011] In some embodiments, the distance between the first end and the second end in the first direction is L2, wherein 0.1mm≤L2≤0.2mm.
[0012] In some embodiments, the transition surface includes a second sub-surface that connects the second end and the second sealing surface, and the second sub-surface and the second sealing surface are located in the same plane.
[0013] In some embodiments, the second sub-surface has a third end and a fourth end opposite each other in a second direction, the third end being connected to the first sub-surface and the fourth end being connected to the second sealing surface, and the distance between the third end and the fourth end in the second direction is L3, wherein 0.5mm≤L3≤1mm.
[0014] In some embodiments, the injection mold includes:
[0015] The second slider and the first slider are disposed on opposite sides of the inner mold along the first direction, and the second sealing surface, the transition surface and the glue position surface are connected in sequence along the second direction;
[0016] Two third sliders are disposed on opposite sides of the inner mold along a third direction, wherein the first direction, the second direction, and the third direction are perpendicular to each other.
[0017] In some embodiments, the injection mold includes:
[0018] A fixed mold, wherein the fixed mold forms a first inner mold groove;

The second inner mold groove and the first inner mold groove enclose an inner mold cavity. The inner mold, the first slider, the second slider and the two third sliders are all located in the inner mold cavity to jointly define the cavity.

[0021] In the injection mold provided in this application embodiment, the second sealing surface and the glue position surface are located in the same plane, while the transition surface connects the second sealing surface and the glue position surface.

[0031] To make the objectives, technical solutions, and advantages of this application clearer, embodiments of the technical solutions of this application will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solutions of this application more clearly, and are therefore merely examples and should not be used to limit the scope of protection of this application.
[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this application.
[0033] In the description of the embodiments of this application, the technical terms "first", "second", etc. are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features.
[0034] In this document, the term "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that combinations can be made in any suitable manner without contradiction; for example, different combinations of specific technical features / embodiments can form different implementations. To avoid unnecessary repetition, the various possible combinations of specific technical features / embodiments in this application will not be described separately.
[0035] Please see Figures 1 to 6 This application provides an injection mold, which includes a first slider 1 and an inner mold 2. The first slider 1 includes a first sealing surface 11, and the inner mold 2 includes a second sealing surface 21, a glue position surface 22, and a transition surface 23. The transition surface 23 connects the second sealing surface 21 and the glue position surface 22. The second sealing surface 21 is in contact with the first sealing surface 11. The glue position surface 22 and the transition surface 23 are both part of the cavity wall surface of the cavity 10a. The second sealing surface 21 and the glue position surface 22 are located in the same plane, and at least a portion of the transition surface 23 and the glue position surface 22 are not in the same plane.
[0036] Cavity 10a is a closed space formed by the injection mold. Cavity 10a is used to form product 100. The shape and size of cavity 10a match product 100. It is a space in which the melt is filled, cooled and solidified under the action of injection pressure.
[0037] Melt is a plastic raw material in a molten state.
[0038] In the embodiments of this application, please refer to Figure 7Product 100 can be the frame of an indoor air conditioner unit. An indoor air conditioner unit is a device used indoors to regulate indoor temperature and / or humidity. In use, the indoor air conditioner unit can be mounted on a wall or other indoor structure. The frame is generally a hollow frame structure, forming an air inlet and an air outlet. The space inside the frame can be used to house components such as a fan and heat exchanger. In this embodiment, product 100 is used as an example for illustration. Please refer to [link to relevant documentation]. Figure 7 The face frame includes a grid 110 composed of intersecting horizontal and vertical ribs.
[0039] The first slider 1 is slidable. For example, the first slider 1 can slide in a direction intersecting the mold opening direction. The first slider 1 can be used for demolding structures such as the grid 110 of the product 100.
[0040] The first slider 1 and the inner mold 2 can cooperate to form part of the cavity 10a, and the melt fills the cavity to form part of the structure of the product 100.
[0041] The first sealing surface 11 and the second sealing surface 21 are mating surfaces used to seal the cavity 10a to prevent the melt from overflowing from the cavity 10a.
[0042] The adhesive surface 22 and the transition surface 23 are both part of the cavity wall surface of the cavity 10a, that is, the adhesive surface 22 and the transition surface 23 are the molding surfaces of the cavity 10a. The adhesive surface 22 and the transition surface 23 are used to directly contact the melt in the cavity 10a and finally form part of the surface of the product 100.
[0043] Taking the face frame as an example, the second sealing surface 21 is bonded to the first sealing surface 11 to seal the cavity 10a and prevent the melt from overflowing from the cavity 10a. The adhesive surface 22 and the transition surface 23 are both used to form at least part of the surface of the grid 110.
[0044] The second sealing surface 21 is bonded to the first sealing surface 11, so that the second sealing surface 21 and the first sealing surface 11 are sealed and abutted.
[0045] If the second sealing surface 21 and the adhesive surface 22 are located in the same plane, then the second sealing surface 21 and the adhesive surface 22 are coplanar.
[0046] The statement that at least a portion of the transition surface 23 and the adhesive surface 22 are not in the same plane means that either a part of the structure of the transition surface 23 and the adhesive surface 22 are not in the same plane, or the entire structure of the transition surface 23 and the adhesive surface 22 are not in the same plane.
[0047] If at least a portion of the transition surface 23 and the adhesive surface 22 are not in the same plane, then at least a portion of the transition surface 23 and the adhesive surface 22 are not coplanar.
[0048] In related technologies, during the manual polishing of the inner mold's adhesive surface, the sealing surface and the adhesive surface of the inner mold are directly connected and coplanar. It is difficult for operators to distinguish the boundary between the sealing surface and the adhesive surface, and it is easy to polish the sealing surface, resulting in overcutting of the sealing surface. After the sealing surface is overcut, it cannot be sealed, which will cause burrs to appear on the product, such as the grille of the face frame. Burrs refer to the burrs or flash on the edge of the product.
[0049] In the injection mold provided in this embodiment, the second sealing surface 21 and the glue position surface 22 are located in the same plane, while the transition surface 23 connects the second sealing surface 21 and the glue position surface 22. Thus, the transition surface 23 is between the second sealing surface 21 and the glue position surface 22, and the transition surface 23 becomes the boundary between the second sealing surface 21 and the glue position surface 22. Since at least a part of the transition surface 23 and the glue position surface 22 are not in the same plane, it is easy for operators to distinguish the second sealing surface 21 and the glue position surface 22 with the naked eye. During the polishing of the glue position surface 22, the polishing operation on the second sealing surface 21 can be avoided to a certain extent. In this way, the problem of over-cutting caused by polishing the second sealing surface 21 can be avoided to a certain extent, and the risk of burrs can be reduced.
[0050] In some embodiments, there may be one first slider 1. In other embodiments, there may be multiple first sliders 1.
[0051] It should be noted that "multiple" refers to two or more items.
[0052] In some embodiments, the second sealing surface 21 and the adhesive surface 22 are both located on the first plane, and at least a portion of the transition surface 23 is located on the second plane, which intersects with the first plane.
[0053] The phrase "at least part of the transition surface 23 is located in the second plane" means that either a portion of the structure of the transition surface 23 is located in the second plane, or the entire structure of the transition surface 23 is located in the second plane.
[0054] In this embodiment, at least a portion of the transition surface 23 is an inclined flat surface. The second plane where at least a portion of the transition surface 23 is located intersects with the first plane where the glue position surface 22 is located. This facilitates the transition surface 23 to clearly separate the second sealing surface 21 and the glue position surface 22, and also facilitates the separation of the transition surface 23 from the product 100 after injection molding.
[0055] In some embodiments, the transition surface 23 can be a curved surface. In this way, at least a portion of the transition surface 23 and the adhesive surface 22 are not in the same plane, and the transition surface 23 can also be distinguished from the two planes of the second sealing surface 21 and the adhesive surface 22, becoming a visible boundary.
[0056] In some embodiments, please refer to Figure 4The first slider 1 is located on one side of the inner mold 2 in the first direction X. The transition surface 23 includes a first sub-surface 231. The first sub-surface 231 has a first end 2311 and a second end 2312 opposite to each other in the second direction Y. The first end 2311 is connected to the glue surface 22. The second end 2312 is inclined to the side away from the first slider 1. The second direction Y is perpendicular to the first direction X.
[0057] For example, the second sealing surface 21 and the adhesive surface 22 are both located on the first plane, and the first sub-surface 231 can be located on the second plane.
[0058] In this embodiment, the first sub-surface 231 is an inclined flat surface. The first sub-surface 231 extends inclinedly away from the first slider 1. The plane containing the first sub-surface 231 intersects with the plane containing the glue-position surface 22. In this way, the first sub-surface 231 can provide a relatively clear visual boundary, which is beneficial for operators to see the first sub-surface 231, thereby avoiding the problem of polishing the second sealing surface 21 during the polishing of the glue-position surface 22. The first sub-surface 231 extends inclinedly away from the first slider 1, which facilitates the movement of the first slider 1 along the first direction X away from the inner mold 2 during the demolding process.
[0059] In some embodiments, please refer to Figure 4 The distance between the first end 2311 and the second end 2312 in the second direction Y is L1, where 1mm≤L1≤2mm.
[0060] For example, the distance L1 between the first end 2311 and the second end 2312 in the second direction Y can be any value among 1mm, 1.1mm, 1.3mm, 1.5mm, 1.8mm and 2mm or any value between two of them.
[0061] It should be noted that the distance L1 between the first end 2311 and the second end 2312 in the second direction Y refers to the perpendicular distance between the first end 2311 and the second end 2312 in the second direction Y.
[0062] In this embodiment, the first sub-surface 231 is in direct contact with the melt. The first sub-surface 231 is the forming surface. The distance L1 between the first end 2311 and the second end 2312 in the second direction Y is between 1 mm and 2 mm. The size of the first sub-surface 231 is appropriate, which makes it easy for operators to visually view the first sub-surface 231, and also does not affect the surface of the product 100. This prevents obvious steps from forming on the surface of the product 100 that are scratchy, thus improving the quality of the product 100.
[0063] The unit "mm" stands for millimeter.
[0064] In some embodiments, please refer to Figure 4The distance between the first end 2311 and the second end 2312 in the first direction X is L2, where 0.1mm≤L2≤0.2mm.
[0065] For example, the distance L2 between the first end 2311 and the second end 2312 in the first direction X can be any value among 0.1mm, 0.11mm, 0.13mm, 0.15mm, 0.18mm and 0.2mm or any value between two of them.
[0066] It should be noted that the distance L2 between the first end 2311 and the second end 2312 in the first direction X refers to the perpendicular distance between the first end 2311 and the second end 2312 in the first direction X.
[0067] In this embodiment, the first sub-surface 231 is in direct contact with the melt. The first sub-surface 231 is the forming surface. The distance L2 between the first end 2311 and the second end 2312 in the first direction X is between 0.1mm and 0.2mm. The size of the first sub-surface 231 is appropriate, which makes it easy for operators to visually view the first sub-surface 231, and also does not significantly affect the surface of the product 100.
[0068] Understandably, the first sub-surface 231 is used to form part of the surface of the grille 110 of the product 100, such as the face frame. The first sub-surface 231 can also be polished. Of course, if the size of the first sub-surface 231 is relatively small, the first sub-surface 231 can also be left unpolished, which will basically not affect part of the surface of the grille 110.
[0069] In some embodiments, please refer to Figure 4 The transition surface 23 includes a second sub-surface 232, which connects the second end 2312 and the second sealing surface 21. The second sub-surface 232 and the second sealing surface 21 are located in the same plane.
[0070] For example, the second sealing surface 21 and the second sub-surface 232 are both located on the first plane.
[0071] In this embodiment, the second sub-surface 232 is a flat surface. Since the second sub-surface 232 and the second sealing surface 21 are located in the same plane, the second sub-surface 232 and the first sub-surface 231 are not in the same plane, that is, the second sub-surface 232 and the first sub-surface 231 are not coplanar. With this design, the first sub-surface 231 connects the second sub-surface 232 and the adhesive surface 22. The connection between the first sub-surface 231 and the second sub-surface 232 forms a step. The second sub-surface 232 can further isolate the adhesive surface 22 and the second sealing surface 21, making it easy to distinguish with the naked eye. This avoids polishing operations on the second sealing surface 21, improving reliability. The second sub-surface 232 can also isolate the second sealing surface 21 and the first sub-surface 231, which can hide the first sub-surface 231 and further reduce the impact on the surface of the product 100.
[0072] In some embodiments, the transition surface 23 may also not have a second sub-surface 232, and the first sub-surface 231 connects the adhesive surface 22 and the second sealing surface 21.
[0073] In some embodiments, please refer to Figure 4 The second sub-surface 232 has a third end 2321 and a fourth end 2322 in the second direction Y. The third end 2321 is connected to the first sub-surface 231, and the fourth end 2322 is connected to the second sealing surface 21. The distance between the third end 2321 and the fourth end 2322 in the second direction Y is L3, where 0.5mm≤L3≤1mm.
[0074] For example, the distance L3 between the third end 2321 and the fourth end 2322 in the second direction Y can be any value of 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm and 1mm or a value between any two of them.
[0075] It should be noted that the distance L3 between the third end 2321 and the fourth end 2322 in the second direction Y refers to the perpendicular distance between the third end 2321 and the fourth end 2322 in the second direction Y.
[0076] In this embodiment, the second sub-surface 232 is in direct contact with the melt and is a molding surface. The distance L3 between the third end 2321 and the fourth end 2322 in the second direction Y is between 0.5mm and 1mm. The size of the second sub-surface 232 is appropriate, which can separate the first sub-surface 231 and the second sealing surface 21, and can basically not affect the surface of the product 100.
[0077] Understandably, the second sub-surface 232 is used to form part of the surface of the grille 110 of the product 100, such as the face frame. The size of the second sub-surface 232 is relatively small, and the second sub-surface 232 does not need to be polished, so it will not have much impact on part of the surface of the grille 110.
[0078] In some embodiments, please refer to Figure 1 The injection mold includes a second slider 3 and two third sliders 4. The second slider 3 and the first slider 1 are disposed on opposite sides of the inner mold 2 along the first direction X. The second sealing surface 21, the transition surface 23 and the glue position surface 22 are connected in sequence along the second direction Y. The two third sliders 4 are disposed on opposite sides of the inner mold 2 along the third direction Z. The first direction X, the second direction Y and the third direction Z are perpendicular to each other.
[0079] The first slider 1 is capable of sliding; for example, the first slider 1 can slide in a first direction X.
[0080] The second slider 3 can slide, for example, the first slider 1 can slide in the first direction X.
[0081] The third slider 4 is capable of sliding; for example, the third slider 4 can slide in the third direction Z.
[0082] In this embodiment, the first slider 1, the second slider 3, and the two third sliders 4 together form a placement space, and the inner mold 2 is located in the placement space. In this way, the first slider 1, the second slider 3, the two third sliders 4, and the inner mold 2 can form a cavity for accommodating the melt.
[0083] In some embodiments, please refer to Figure 1 The injection mold includes a fixed mold 5 and a moving mold. The fixed mold 5 forms a first inner mold groove. The moving mold and the fixed mold 5 are arranged along the second direction Y. The moving mold forms a second inner mold groove. The second inner mold groove and the first inner mold groove enclose each other to form an inner mold cavity. The inner mold 2, the first slider 1, the second slider 3 and the two third sliders 4 are all located in the inner mold cavity to jointly define the cavity 10a.
[0084] The fixed mold 5 can remain stationary, while the moving mold can move relative to the fixed mold 5 along the second direction Y, which can be the mold opening direction.
[0085] The injection mold has an injection position and a demolding position. In the injection position, the moving mold and the fixed mold 5 are closed, and the second inner mold groove and the first inner mold groove are enclosed to form an inner mold cavity. In the demolding position, the moving mold separates from the fixed mold 5 along the second direction Y.
[0086] When the injection mold is in the demolding position, the moving mold moves away from the fixed mold 5 along the second direction Y to separate from the fixed mold 5, allowing the molded product 100 to be removed, thus achieving demolding. When the injection mold is in the injection position, the moving mold moves closer to the fixed mold 5 along the second direction Y to close with the fixed mold 5, thereby performing injection molding. The inner mold cavity is formed by the second inner mold groove and the first inner mold groove. When the moving mold is separated from the fixed mold 5, the first slider 1, the second slider 3, and the two third sliders 4 can all slide, allowing them to separate from the inner mold 2, enabling the product 100 to detach from the inner mold 2. After the moving mold and the fixed mold 5 close, the inner mold 2, the first slider 1, the second slider 3, and the two third sliders 4 are embedded within the inner mold cavity.
[0087] This application also provides an injection molding apparatus, including the injection mold in any embodiment of this application.
[0088] The injection molding apparatus may also include an injection molding machine that injects the melt into the cavity 10a of the injection mold.
[0089] An injection molding machine is a device used to heat and melt plastic raw materials into a molten substance, which is then injected into an injection mold to form the final product.
[0090] Injection molding machines can adopt existing structures, and this application does not impose any restrictions.
[0091] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application. In particular, as long as there is no structural conflict, the various technical features mentioned in each embodiment can be combined in any way.
