Description

Technical Field

[0001] This disclosure relates to the field of molding technology, and in particular to an air guiding device and a mold assembly. Background Technology

[0002] In the stamping die production process, closed cavities exist. Poor venting of gas from these cavities can affect the quality of stamped parts. In related technologies, venting structures can negatively impact the appearance and quality of exterior parts, leading to defects. Utility Model Content

[0003] To overcome the problems existing in the related technologies, this disclosure provides an air guiding device and a mold assembly.

[0004] According to a first aspect of the present disclosure, an air guiding device is provided, comprising: a main body for insertion into a mold body; and a pore structure disposed within the main body, wherein the pore structure has a plurality of spaced-apart through holes to allow the cavity of the mold body to communicate with the outside through the through holes, wherein the diameter of the through holes is not greater than 1 mm.

[0005] By incorporating the air guiding device of this embodiment into the mold body, the sealed cavity can be vented. Furthermore, the diameter of the venting hole is no greater than 1 mm, providing effective support to the sheet metal during venting. After the mold body is removed, the molded part will experience slight springback and material surface tension, causing the shallow depression at the orifice to be flattened by the surrounding material, thereby resolving part defects and preventing any impact on the part's appearance.

[0006] In some possible embodiments, the diameter of the via is not less than 0.5 mm to ensure venting effect and reduce damage to the parts.

[0007] In some possible embodiments, the body is constructed as a cavity structure, and the porous structure covers at least a portion of the cavity wall of the body in the extending direction of the body, in order to save manufacturing costs and ensure venting effect.

[0008] In some possible embodiments, the extension length of the via is not less than 20mm, which can ensure that the via has a certain machining allowance and will not be completely machined away due to cutting.

[0009] In some possible embodiments, the main body is constructed as a cavity structure, and the wall thickness of the cavity wall of the main body is not less than 3mm, so that the main body can be matched with different mold bodies for processing and to ensure processing allowance.

[0010] In some possible embodiments, the porous structure is constructed as a 3D printed part.

[0011] 3D printing makes it easier to print through holes no larger than 1mm, and multiple holes can be printed at the same time, improving production efficiency.

[0012] In some possible embodiments, one end of the pore structure is provided with a conical recess, the cone angle of which is 90° to 110°.

[0013] This structure provides support when printing porous structures, making printing easier and eliminating the need for additional support structures, thus saving on materials.

[0014] In some possible embodiments, one end of the main body is formed with a circumferentially outwardly extending shoulder for attaching to the mold body, thereby axially positioning the air guide device and preventing it from extending too far and affecting the mold body's processing and forming of the sheet metal.

[0015] In some possible embodiments, the shoulder has a stop plane formed laterally to mate with a limiting plane on the mold body to restrict the rotation of the air guiding device and ensure the installation stability of the main body.

[0016] In some possible embodiments, the air guiding device includes a clamping member disposed at one end of the main body where the shoulder is formed, for pressing the shoulder against the mold body. The clamping member allows for axial positioning of the main body, restricting axial displacement under the action of the shoulder and the clamping member, thus ensuring the stability of the main body.

[0017] According to a second aspect of the present disclosure, a mold assembly is provided, including a mold body and an air guiding device of the present disclosure. The mold body has an internal cavity and a through hole. The main body is shaped and disposed in the through hole so that the through hole communicates the cavity with the outside.

[0018] The technical solutions provided by the embodiments of this disclosure can include the following beneficial effects: By setting the air guiding device of the embodiments of this disclosure in the mold body, the effect of venting the sealed cavity can be achieved. Furthermore, the diameter of the through hole used for venting is no greater than 1 mm, which can provide effective support for the sheet metal during venting. When the mold body is removed, the molded part will, due to slight springback and material surface tension, cause the shallow depression at the orifice of the through hole to be flattened by the surrounding material, thereby solving the part defect and avoiding any impact on the part's appearance.

[0019] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

Detailed Implementation

[0031] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0032] In the stamping die production process, closed cavities exist. Poor gas venting from these cavities can negatively impact the quality of stamped parts. In related technologies, venting structures can affect the appearance and quality of parts, leading to defects. For example, some existing technologies use venting holes on the die for venting. These venting holes are relatively large, typically over 4mm. At the moment of gas venting, a local pressure difference is created at the venting hole, causing the surface of the stamped part to be drawn towards the venting hole under the pressure difference, leaving a hole mark on the stamped part. This affects both the appearance and quality of the stamped part.

[0033] Therefore, this disclosure provides an air guiding device 100 to solve the above-mentioned defects. (Refer to...) Figures 1 to 8 The air guiding device 100 includes a main body 10 and a porous structure 20. The main body 10 is inserted into a mold body 200. For example, a through hole 203 can be formed in the mold body 200, and the main body 10 can be inserted into the through hole 203 with a form fit. The porous structure 20 is disposed within the main body 10 and has multiple spaced through holes 21 to connect the cavity 201 of the mold body 200 with the outside, thereby venting air from the closed cavity 201. The diameter of the through holes 21 is no greater than 1 mm.

[0034] By using the above technical solution, the air guiding device 100 of this embodiment is provided in the mold body 200, which can achieve the effect of venting the sealed cavity 201. Furthermore, the diameter of the through hole 21 used for venting is no greater than 1 mm, which can provide effective support for the sheet metal 300 during venting. When the mold body 200 is removed, the molded part will, due to slight springback and material surface tension, cause the shallow depression at the opening of the through hole 21 to be flattened by the surrounding material, thereby resolving part defects and avoiding any impact on the appearance of the part.

[0035] The diameter of the through hole 21 shall not be less than 0.5mm to ensure the venting effect and reduce damage to the parts. If the diameter of the through hole 21 is too small, it will affect the venting effect and make it difficult to manufacture. In addition, it is easy to be blocked by residues. If the diameter of the through hole 21 is too large, it will easily produce hole marks on the parts, affecting the appearance and quality of the parts.

[0036] Reference Figure 2 As shown, the main body 10 can be constructed as a cavity structure, in the extending direction of the main body 10, that is, in Figure 2 In the vertical direction shown in the figure, the porous structure 20 can cover at least a portion of the cavity wall of the main body 10 to save manufacturing costs and ensure exhaust effect. In other words, the length extended by the porous structure 20 can be the same as the length extended by the cavity wall of the main body 10, or it can be as follows: Figure 2In this structure, the pore structure 20 extends only to a portion of the cavity wall, rather than completely covering it.

[0037] In this embodiment of the disclosure, reference is made to Figure 2 The length L of the via 21 shall not be less than 20mm. When... Figure 2 When there are multiple through holes 21 of various lengths, the length of all through holes 21 shall not be less than 20mm. That is to say, the length of the shortest through hole 21 can be set to not less than 20mm. Since the mold body 200 is sometimes matched with stamping parts for secondary processing, setting the length of the through hole 21 to not less than 20mm can ensure that the through hole 21 has a certain machining allowance and will not be completely machined away due to cutting.

[0038] It is understood that the length of the main body 10 in this embodiment is not less than 20mm, in order to allow for machining allowance.

[0039] In this embodiment, the main body 10 is constructed as a cavity structure, and the wall thickness D of the cavity wall of the main body 10 is not less than 3mm, so that the main body 10 can be matched with different mold bodies 200 for processing, ensuring processing allowance.

[0040] In this embodiment, the outer diameter of the main body 10 can be no less than 20mm, for example, 20mm. If the outer diameter of the main body 10 is too small, more through holes need to be opened on the mold body 200 to meet the venting effect, which is costly and time-consuming to install. The 20mm outer diameter conforms to the design concept of standard parts, making selection and matching more convenient and reliable.

[0041] In this embodiment, the porous structure 20 can be constructed as a 3D printed part. 3D printing makes it easier to print through holes 21 no larger than 1 mm, and multiple holes can be printed simultaneously, improving production efficiency.

[0042] Reference Figure 2 As shown, one end of the porous structure 20 has a conical recess 22, the cone angle of which is 90°~110°, such as 100°. When printing the porous structure 20, this structure provides support, facilitating printing and eliminating the need for additional support structures, thus saving material.

[0043] In other embodiments, additional support structures may be printed to support the printing of the porous structure 20.

[0044] Reference Figure 2 and Figure 7 One end of the main body 10 may have a circumferentially outwardly extending shoulder 12 for attaching to the mold body 200. For example, see reference... Figure 4 and Figure 6A recessed step 204 can be formed on the mold body 200. After the main body 10 is inserted into the through hole 203, the shoulder 12 can overlap on the recessed step 204, thereby axially positioning the air guide device 100 and avoiding excessive insertion which would affect the processing and forming of the sheet metal 300 by the mold body 200.

[0045] Reference Figure 1 and Figure 2 The air guiding device 100 may further include a clamping member 30, which may be disposed at one end of the main body 10 where a shoulder 12 is formed, for pressing the shoulder 12 against the mold body 200. The clamping member 30 can axially position the main body 10, restricting axial displacement under the action of the shoulder 12 and the clamping member 30, thus ensuring the stability of the main body 10. The clamping member 30 can be fastened to the mold body 200 with bolts. An opening 31 is provided in the middle region of the clamping member 30 to allow air to escape through the through hole 21.

[0046] In this embodiment of the disclosure, reference is made to Figure 7 The shoulder 12 may have a stop plane 121 formed on its side, which is used to mate with the limiting plane 202 on the mold body 200 to limit the rotation of the air guiding device and prevent instability of the main body 10 installation. The limiting plane 202 can be directly machined from the mold body 200, such as... Figure 6 As shown. In other embodiments, the limiting plane 202 can also be provided on the mold body 200 as a limiting member 2021, and is formed by machining on the limiting member 2021. However, when providing the limiting member 2021, refer to... Figure 4 As shown, a recessed notch 205 may be provided on the mold body 200, and a limiting member 2021 may be accommodated in the recessed notch 205. The limiting member 2021 may be fastened in the recessed notch 205 by bolts.

[0047] Reference Figure 1 , Figure 2 and Figure 8 In a second aspect, this disclosure provides a mold assembly including a mold body 200 and the aforementioned air guiding device 100. The mold body 200 has an internal cavity 201, and a through hole 203 is provided on the mold body 200. The main body 10 is shaped and disposed within the through hole 203 so that the through hole 21 communicates the cavity 201 with the outside. The mold body 200 may include a punch and a die, wherein the punch is... Figure 8 The upper middle mold body is 200, and the cavity mold is... Figure 8The lower part of the mold body 200 has a sheet metal 300 placed between the punch and the die. When the sheet metal 300 is formed, a sealed cavity 201 is formed between one side of the mold body 200 and the sheet metal 300. By providing an air guide device 100, the cavity 201 can be vented, solving the problems of springback deformation of parts and material carrying difficulties caused by poor venting. The mold assembly in this embodiment has all the beneficial effects of the air guide device 100, which will not be described in detail here.

[0048] like Figure 8 As shown, multiple air guiding devices 100 can be provided on the mold body 200 to ensure the air exhaust effect. Figure 8 The middle arrow indicates the direction of the exhaust airflow. The number of air guiding devices 100 can be adjusted according to the volume of the cavity 201.

[0049] In the above detailed description, reference has been made to the accompanying drawings, which illustrate specific aspects of this disclosure by way of illustration. In this regard, terms indicating direction or positional relationship, such as “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “clockwise,” “counterclockwise,” “axial,” “radial,” and “circumferential,” are used with reference to the orientation of the described figures. Since components of the described device can be positioned in multiple different orientations, directional terms are used for illustrative purposes and not for limitation. It should be understood that other aspects can be utilized and structural or logical changes can be made without departing from the concept of this disclosure. Therefore, the following detailed description should not be considered limiting.

[0050] It should be understood that, unless otherwise specifically indicated, features of various embodiments of this disclosure described herein can be combined with each other. As used herein, the term “and / or” includes any one of the relevant listed items and any combination of any two or more; similarly, “at least one of…” includes any one of the relevant listed items and any combination of any two or more.

[0051] It should be understood that, unless otherwise expressly specified and limited, the terms "joining," "attaching," "installing," "connecting," "linking," "fixing," etc., used in the embodiments of this disclosure should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms herein based on the specific circumstances.

[0052] Furthermore, the term "above" as used herein with respect to components, elements, or material layers formed or located "above" a surface may be used to indicate that the component, element, or material layer is "indirectly" positioned (e.g., placed, formed, deposited, etc.) on the surface such that one or more additional components, elements, or layers are arranged between the surface and the component, element, or material layer. However, the term "above" as used with respect to components, elements, or material layers formed or located "above" a surface may also optionally have a specific meaning: that the component, element, or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, for example, in direct contact with the surface.

[0053] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited to these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, the first component, part, region, layer, or section mentioned in the examples may also be referred to as the second component, part, region, layer, or section. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0054] It should be understood that spatial relative terms, such as “above,” “upper,” “below,” and “lower,” are used herein to describe the relationship between one element and another shown in the figures. In addition to the orientation depicted in the figures, these spatial relative terms are also intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “above” or “upper” relative to another element would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0055] Furthermore, the term “exemplary” is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as “exemplary” is not necessarily to be construed as advantageous compared to other aspects or designs. Rather, the use of the term “exemplary” is intended to present the concept in a concrete manner. As used herein, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless otherwise specified or clear from the context, “X applies A or B” is intended to mean any of the natural inclusive arrangements. That is, “X applies A or B” satisfies any of the foregoing instances if X applies A; X applies B; or both X applies A and B. Additionally, unless otherwise specified or clear from the context to refer to the singular form, the articles “a” and “an” as used in this application and the appended claims are generally understood to mean “one or more.”

[0056] Similarly, although this disclosure has been shown and described with respect to one or more implementations, equivalent variations and modifications will occur to those skilled in the art upon reading and understanding this specification and the accompanying drawings. This disclosure includes all such modifications and variations and is limited only by the scope of the claims. In particular, with respect to the various functions performed by the components described above (e.g., elements, resources, etc.), unless otherwise indicated, the terminology used to describe such components is intended to correspond to any component (functionally equivalent) that performs the specific function of the described component, even if structurally not equivalent to the disclosed structure.
