Description

Technical Field

[0001] This utility model relates to the field of aircraft aerodynamic system technology, and in particular to an S-curve air intake forming mold. Background Technology

[0002] As a crucial component of aerospace vehicles, the manufacturing quality of the S-curve air intake directly impacts engine efficiency. Currently, the molding dies for traditional S-curve air intakes often employ a one-piece rigid male mold structure, which presents the following technical problems: Due to the complex double-bend geometry and large length-to-diameter ratio of the S-curve air intake, the use of an integral rigid male mold results in severe interference during demolding. Demolding requires pulling the mold out along the air intake axis, but the S-shaped bend makes this straight-line demolding method impossible. Forced demolding can damage the inner surface of the product or even jam the mold, affecting yield.

[0003] In summary, there is an urgent need for a molding die that can be quickly and fully demolded after the S-curve air intake is formed, without damaging the air intake structure. Utility Model Content

[0004] To solve the above problems, this utility model provides an S-curve air intake forming mold.

[0005] The technical solution adopted in this utility model is as follows: An S-curve air intake forming mold includes: The male mold body includes a base, a head male mold, and a tail male mold, wherein... The middle part of the base is bent into an S-shape and is adapted to the inner wall shape of the S-curve section of the required S-curve air intake. The end of the base near the head end of the S-curve air intake is the large end, which is provided with a first inclined surface. The end near the tail end of the S-curve air intake is the small end, which is provided with a second inclined surface. A first groove is provided on the first inclined surface, and a second groove is provided on the second inclined surface. The head end male mold is provided with a third inclined surface that matches the shape of the first inclined surface. A first slider is provided on the third inclined surface. The first slider is slidably connected to the first groove. When the third inclined surface covers and fits the first inclined surface, the head end male mold is spliced ​​with the large end to form a shape that matches the inside of the S-curve air intake head end. The tail end male mold is provided with a fourth inclined surface that matches the shape of the second inclined surface. A second slider is provided on the fourth inclined surface. The second slider is slidably connected to the second groove. When the fourth inclined surface covers and fits the second inclined surface, the tail end male mold is spliced ​​with the small end to form a shape that matches the inside of the tail end of the S-curve air intake channel. A support clamp is located below the base and clamps the base.

[0006] In one possible implementation, The first inclined surface is located at the edge of the large end near the head of the S-curve air intake, and the opposite side is located in the middle of the base and on the side away from the first side. The second inclined surface is located at the edge of the small end near the tail end of the S-curve air intake, and the opposite side is located in the middle of the base and on the side away from the opposite side.

[0007] In one possible implementation, A first spring is provided inside the first slide groove. The first spring is at least located on one side of the first slider. One end of the first spring is installed on the inner wall of the first slide groove, and the other end is installed on the side wall of the first slider. A second spring is provided inside the second slide groove. The second spring is at least located on one side of the second slider. One end of the second spring is installed on the inner wall of the second slide groove, and the other end is installed on the side wall of the second slider.

[0008] In one possible implementation, The substrate includes a first unit and a second unit. The first unit has a first connecting surface and the second unit has a second connecting surface. The first connecting surface and the second connecting surface are attached to each other at the S-curve section of the S-curve intake. Multiple connecting ball heads and connecting ball grooves are alternately arranged on both the first and second connecting surfaces. The multiple connecting ball heads and multiple connecting ball grooves correspond one-to-one and are embedded and connected.

[0009] In the above possible implementations, further, It also includes a third slider and a third groove, wherein: The third slider is located at the bottom of the support fixture, the third groove is located below the support fixture, and the third slider is slidably connected in the third groove. The sliding direction of the third groove is parallel to the length direction of the S-curve air intake; There are multiple support clamps, which respectively clamp the first unit and the second unit.

[0010] In one possible implementation, It also includes mold plates, multiple mold plates are magnetically connected to the outer wall of the male mold body, and multiple mold plates are spliced ​​with the male mold body to form a shape that fits the required S-curve air intake channel.

[0011] The technical solution provided in this application has at least the following technical effects or advantages: The S-bend air intake molding die provided in this application features sliding head and tail male molds. After the S-bend air intake is fitted into the die and cured, pulling out the head and tail male molds shortens the diameter of the die at the head and tail ends, allowing the formed air intake to fully detach from the die. The air intake can then be loosened and pulled out from the smaller-diameter tail end. Compared to commonly used rigid one-piece molding dies, demolding is faster and more complete, and the formed air intake will not be damaged during demolding. Attached Figure Description

Detailed Implementation

[0015] The specific implementation of the present invention will now be described with reference to the accompanying drawings.

[0016] Example 1 like Figures 1-2 As shown, this embodiment provides an S-curve intake manifold forming mold, which includes: The male mold body includes a base 1, a head male mold 2, and a tail male mold 3, wherein... The middle part of the base 1 is bent into an S-shape and is adapted to the inner wall shape of the S-curve section of the required S-curve air intake. The end of the base 1 near the head end of the S-curve air intake is the large end, which is provided with a first inclined surface. The end near the tail end of the S-curve air intake is the small end, which is provided with a second inclined surface. A first groove 6 is provided on the first inclined surface, and a second groove 9 is provided on the second inclined surface. The head end male mold 2 is provided with a third inclined surface that matches the shape of the first inclined surface. A first slider 5 is provided on the third inclined surface. The first slider 5 is slidably connected to the first groove 6. When the third inclined surface covers and fits the first inclined surface, the head end male mold 2 is spliced ​​with the large end to form a shape that matches the inside of the S-curve air intake. The tail end male mold 3 is provided with a fourth inclined surface that matches the shape of the second inclined surface. A second slider 8 is provided on the fourth inclined surface. The second slider 8 is slidably connected to the second slide groove 9. When the fourth inclined surface covers and fits the second inclined surface, the tail end male mold 3 is spliced ​​with the small end to form a shape that matches the inside of the tail end of the S-curve air intake channel. Support clamp (4) is located below the base 1 and clamps the base 1.

[0017] like Figure 1 As shown, in this embodiment, the support clamp (4) is clamped at the bottom of the base 1, providing support for the entire male mold body. The first inclined surface on the large end side of the base 1 is inclined to the lower left, and the second inclined surface on the small end side is inclined to the lower right. Taking the working mode of the head end male mold 2 in this mold as an example: when the third inclined surface of the head end male mold 2 slides down along the inclined direction of the first inclined surface, it will slide out of the head end of the formed S-curve air intake channel and empty the internal space near the head end of the S-curve air intake channel. At this time, the head end of the air intake channel has completed rapid demolding. The same applies to the tail end male mold 3. When it slides out of the tail end of the air intake channel, the tail end of the air intake channel has also completed demolding. At this time, it is only necessary to pull out the entire air intake channel to achieve complete demolding. Compared with the commonly used rigid one-piece mold, demolding is fast and does not damage the formed air intake channel.

[0018] In this embodiment, The first inclined surface is located at the edge of the large end near the head end of the S-curve air intake, and the opposite side is located in the middle of the base 1 and on the side away from the first side. The second inclined surface is located at the edge of the small end near the tail end of the S-curve air intake, and the opposite side is located in the middle of the base 1 and on the side away from the opposite side.

[0019] like Figure 1 , 2As shown in this embodiment, this configuration can increase the slope of the first and second inclined surfaces, enabling the head end male mold 2 and the tail end male mold 3 to achieve a larger mold diameter change within a shorter sliding distance, resulting in faster demolding.

[0020] In this embodiment, A first spring 7 is provided inside the first slide groove 6. The first spring 7 is provided at least on one side of the first slider 5. One end of the first spring 7 is installed on the inner wall of the first slide groove 6, and the other end is installed on the side wall of the first slider 5. A second spring 10 is provided inside the second slide groove 9. The second spring 10 is provided at least on one side of the second slider 8. One end of the second spring 10 is installed on the inner wall of the second slide groove 9, and the other end is installed on the side wall of the second slider 8.

[0021] like Figure 2 As shown, in this embodiment, a first spring 7 is provided in the first slide groove 6 and a second spring 10 is provided in the second slide groove 9, which can keep the head end male mold 2 and the tail end male mold 3 in contact with the base 1 during use, thereby ensuring the molding effect and bonding stability when the air intake is bonded and molded; and after the head end male mold 2 and the tail end male mold 3 are pulled out and demolded, the head end male mold 2 and the tail end male mold 3 can quickly and automatically rebound under the action of the first spring 7 and the second spring 10.

[0022] Example 2 like Figures 3-4 As shown, this embodiment provides an S-curve intake manifold forming mold, the structure of which is basically the same as that of Embodiment 1, the difference being: The substrate 1 includes a first unit 101 and a second unit 102. The first unit 101 has a first connecting surface and the second unit 102 has a second connecting surface. The first connecting surface and the second connecting surface are attached to each other at the S-curve section of the S-curve intake. Multiple connecting ball heads 1101 and connecting ball grooves 1102 are alternately arranged on both the first and second connecting surfaces. The multiple connecting ball heads 1101 and the multiple connecting ball grooves 1102 correspond one-to-one and are embedded and connected.

[0023] like Figure 3 , 4 As shown, this embodiment differs from Embodiment 1 primarily in its configuration of the substrate 1. It is now designed as a split structure, with the separate first unit 101 and second unit 102 connected and fixed to each other via staggered connecting ball heads 1101 and connecting ball grooves 1102. The split substrate 1 at the S-bend is more suitable for demolding complex or highly curved S-bend structures compared to Embodiment 1. Furthermore, the detachable and interlocking connection between the first unit 101 and the second unit 102 via the connecting ball heads 1101 and connecting ball grooves 1102 facilitates easy disassembly and connection, resulting in high demolding efficiency and good bonding stability and integrity during molding.

[0024] Example 3 like Figure 5 As shown, this embodiment provides an S-curve intake manifold forming mold, the structure of which is basically the same as that of embodiment 2, the difference being: It also includes a third slider 13 and a third groove 14, wherein: The third slider 13 is disposed at the bottom of the support clamp (4), the third slide groove 14 is disposed below the support clamp (4), and the third slider 13 is slidably connected in the third slide groove 14; The sliding direction of the third slide groove 14 is parallel to the length direction of the S-curve air intake; There are multiple support clamps (4), which are respectively clamped on the first unit 101 and the second unit 102.

[0025] like Figure 5 As shown, compared to Embodiment 2, this embodiment further adds a third slide groove 14 and a third slider 13, which facilitates flexible assembly and disassembly of the first unit 101 and the second unit 102, making demolding more convenient. Furthermore, in a further preferred embodiment, a spring can be added between the two third sliders 13 to tighten them, thereby further improving the fit stability and integrity during air channel molding.

[0026] Example 4 like Figure 6 As shown, this embodiment provides an S-curve intake manifold forming mold, the structure of which is basically the same as that of Embodiment 1, the difference being: It also includes mold plates 12, multiple mold plates 12 are magnetically connected to the outer wall of the male mold body, and multiple mold plates 12 are spliced ​​with the male mold body to form a shape that fits the required S-curve air intake channel.

[0027] Specifically, the shape of the S-curve air intake is often adjusted according to various factors such as target performance parameters and usage scenarios. In this embodiment, by setting up a magnetically connected mold plate 12, and by splicing the mold plate 12 with the male mold body, this mold can be expanded to realize the manufacturing of air intakes with more different shapes. The specific shape, quantity, and magnetic connection position of the mold plate 12 need to be determined according to the requirements of the actual application.

[0028] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on its differences from other embodiments. The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit this application. 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; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of this application.
