Description

Technical Field

[0001] This utility model relates to the field of foam material technology, specifically a foaming mold for a missile adapter. Background Technology

[0002] Prior to the 1970s, tactical missiles generally employed exposed rail-launched systems. With advancements in science and technology and the continuous improvement in missile weapon system performance, more and more tactical missiles began adopting box-launch technology. In the storage and launch box, the adapter installed in the annular gap between the missile and the launch box plays a crucial role in the missile's storage, transportation, loading, unloading, and launch. Materials used to manufacture the adapter typically require excellent dynamic and static compression deformation characteristics, as well as superior properties such as creep resistance and aging resistance. The materials used in adapters mainly include rubber, polyurethane elastomers, polyurethane foam, or mixtures of these materials, with polyurethane elastomers and polyurethane foam being the most widely used. The internal foaming of the foam material exhibits strong nonlinear dynamic characteristics and high damping, thus providing excellent impact resistance. Simultaneously, it effectively prevents the generation of multiple resonance peaks, allowing the inherent characteristics of the structure to avoid broadband excitation frequencies, thereby meeting the performance requirements of different launch platforms for the adapter material. Therefore, the design of the adapter foaming mold is particularly important.

[0003] Adapter foam materials foam rapidly, with a short foaming time. During the foaming process, the intense foaming reaction often generates a large number of bubbles that cannot be expelled in time, leading to product defects. Therefore, traditional adapter foaming molds often employ methods such as... Figure 1 The structure of the combined mold shown avoids dead corners inside the mold cavity, allowing gas to escape from the mold seam and ensuring no defects at the product's edges. During product manufacturing, the metal embedded parts and their fixing cylinders are first fixedly connected to the top cover plate. The four side plates of the mold cavity are then fixedly connected to the bottom plate with screws to form the foaming mold cavity. Polyurethane foam material is then poured into the mold cavity, and finally, the top cover plate is fixedly connected to the mold cavity with screws. While traditional foaming molds have solved the problem of product defects caused by the inability to expel air bubbles in a timely manner to some extent, the excessive number of segments in the combined mold leads to difficulties in mold assembly, low assembly accuracy, and inaccurate positioning of the metal embedded parts, resulting in significant dimensional errors in the product. Furthermore, due to the short foaming process, the foaming mold needs to quickly connect and fix the top cover plate to the mold cavity. The screw connection of traditional molds cannot meet the requirements of rapid connection, resulting in some polyurethane foam overflow, seriously affecting product quality. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] In view of the problems existing in the above and / or existing missile adapter foaming molds, this utility model is proposed.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0007] A missile adapter foaming mold includes a mold body, a fixing mechanism on the mold body, a bottom plate at the bottom of the mold body, and an extension plate on one side of the bottom plate.

[0008] As a preferred embodiment of the missile adapter foaming mold of this utility model, the mold body includes a first mold body and a second mold body connected to each other, and the second mold body is slidably assembled in the first mold body. A mold cavity is opened in the second mold body, and a baffle is provided on one side of the second mold body.

[0009] As a preferred embodiment of the missile adapter foaming mold of this utility model, the fixing mechanism includes a fixing plate disposed on the baffle, a movable plate slidably assembled inside the fixing plate, a uniformly distributed insertion rod on the bottom surface of the movable plate, and a uniformly distributed insertion hole corresponding to the insertion rod on the extension plate.

[0010] As a preferred embodiment of the missile adapter foaming mold described in this utility model, a support plate is provided on one side of the fixed plate, and a screw is rotatably installed on the bottom surface of the support plate, and the screw is screwed into the fixed plate.

[0011] As a preferred embodiment of the missile adapter foaming mold of this utility model, a first gear and a second gear are rotatably mounted on the bottom surface of the support plate. The first gear and the second gear mesh with each other, and the second gear is connected to the screw. An adjusting wheel is rotatably mounted on the first gear and is connected to the first gear.

[0012] As a preferred embodiment of the missile adapter foaming mold described in this utility model, a pull plate is provided on the fixing plate.

[0013] As a preferred embodiment of the missile adapter foaming mold described in this utility model, a limiting plate is provided on one side of the second mold body.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Compared to traditional combination molds, the pull-out structure design increases the assembly speed of the mold, makes it easier for operators to master the assembly points, reduces production preparation time, and improves production efficiency. The first mold body and the second mold body respectively undertake the functions of support and containment. When one part is damaged or needs to be replaced, there is no need to disassemble and replace the entire mold. Only the corresponding part needs to be replaced, which reduces maintenance costs and difficulty, and also improves the versatility and service life of the mold.

[0016] The engagement of the insert rod and the insertion hole makes the second mold body more secure. The design of the adjusting wheel allows the operator to easily adjust the fixing mechanism. The meshing transmission of the first gear and the second gear moves the position of the adjusting wheel away from the first mold body, providing the operator with more hand space and making the operation more comfortable and convenient. The combination of multiple meshing forces further enhances the locking effect, enabling the mold to better resist the pressure and vibration generated by the foaming reaction during the foaming process, thus ensuring the overall stability of the mold.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] Please see Figures 1-4 This utility model provides a technical solution: a missile adapter foaming mold, mainly composed of mold body 1, fixing mechanism 4, base plate 2 and extension plate 3, etc. The components cooperate with each other to achieve efficient and precise foaming operation.

[0028] The mold body 1, as the main part of the mold, is made of high-strength, high-temperature resistant and thermally conductive alloy steel, and is precision cast and machined. The mold body 1 is equipped with a fixing mechanism 4 for fixing and limiting related components. A base plate 2 is fixedly installed at the bottom of the mold body 1. The base plate 2 is made of thick steel plate and has anti-slip rubber pads on its bottom, which can increase the stability of the mold when it is placed and prevent wear on the work platform. An extension plate 3 is vertically welded to one side of the base plate 2. The extension plate 3 is used to cooperate with the fixing mechanism 4 to fix some components of the mold.

[0029] The mold body 1 includes a first mold body 5 and a second mold body 7 connected to each other. The first mold body 5 has a rectangular frame structure and is equipped with a guide rail inside to provide guidance and support for the sliding of the second mold body 7. The second mold body 7 is a rectangular box, the size of which is adapted to the internal space of the first mold body 5 and can be slidably assembled in the first mold body 5. A mold cavity 6 is opened in the second mold body 7. The shape and size of the mold cavity 6 are precisely processed according to the design requirements of the missile adapter to accommodate polyurethane foam material. A baffle 8 is fixedly installed on one side of the second mold body 7. The baffle 8 is rectangular plate-shaped and is used to block the internal space of the first mold body (5). A limit plate (not labeled in detail in the figure) is provided on the other side of the second mold body 7. The limit plate is fixed on the first mold body 5 by bolts to limit the sliding stroke of the second mold body 7 and prevent it from being completely pulled out.

[0030] In use, firstly, the second mold 7 is pulled out from the first mold 5, at which point the mold cavity 6 is fully exposed. Place the prepared metal embedded parts in the corresponding positions within the mold cavity 6 according to the design requirements. Then, pour the prepared polyurethane foam into the mold cavity 6. Next, slowly push the second mold 7 along the guide rail inside the first mold 5 until the second mold 7 fits tightly against the first mold 5. Finally, use the fixing mechanism 4 to limit and fix the second mold 7, ensuring its stable position during the foaming process and preventing displacement. After foaming is complete and the polyurethane foam has cured, loosen the fixing mechanism 4 and pull the second mold 7 out of the first mold 5 to remove the formed missile adapter.

[0031] The mold adopts a pull-out structure design, utilizing the sliding fit between the first mold body 5 and the second mold body 7 to achieve the opening and closing of the mold cavity 6. The first mold body 5 serves as a supporting structure, providing a stable sliding track and supporting force for the second mold body 7. The second mold body 7, as a cavity for containing polyurethane foam material, combines and separates from the first mold body 5 during the sliding process. The limiting plate and baffle cooperate with each other to precisely limit the sliding range of the second mold body 7, ensuring the sealing and stability of the mold cavity 6 during the foaming process. During the foaming process, gas can be discharged through the tiny gap between the first mold body 5 and the second mold body 7, as well as other designed venting channels, to avoid residual air bubbles and ensure product quality.

[0032] Example 2

[0033] Please see Figures 1-4 This utility model provides a technical solution: based on embodiment 1, the fixing mechanism 4 is optimized to further improve the fixing effect and operation convenience of the mold.

[0034] The fixing mechanism 4 includes a fixing plate 9 mounted on the baffle 8. The fixing plate 9 is rectangular and is vertically fixed to the baffle 8 by bolts. A rectangular groove is provided inside the fixing plate 9, and a movable plate 10 is slidably mounted thereon. The movable plate 10 can slide up and down within the groove of the fixing plate 9. Evenly distributed insertion rods 17 are vertically arranged on the bottom surface of the movable plate 10. The insertion rods 17 are cylindrical metal rods. Evenly distributed insertion holes 13 corresponding to the insertion rods 17 are provided on the extension plate 3. The size of the insertion holes 13 is adapted to the insertion rods 17 to ensure that the insertion rods 17 can be smoothly inserted into the insertion holes 13. A support plate 11 is vertically fixed to one side of the fixing plate 9. The support plate 11 is rectangular and is used to support and install related transmission components. A screw 16 is rotatably mounted on the bottom surface of the support plate 11 via bearings. The screw 16 passes vertically through the fixed plate 9 and is screwed to the fixed plate 9. A first gear 14 and a second gear 15 are also rotatably mounted on the bottom surface of the support plate 11 via bearings. The first gear 14 and the second gear 15 mesh with each other, and the second gear 15 is fixedly connected to the screw 16. The rotation of the first gear 14 is transmitted to the screw 16 through gear transmission. An adjusting wheel 18 is fixedly mounted on the first gear 14. The adjusting wheel 18 is a circular disc with anti-slip texture on the surface to facilitate rotation by the operator. The adjusting wheel 18 is connected to the first gear 14 by a key to ensure that the two rotate synchronously. A pull plate 12 is also provided on the fixed plate 9. The pull plate 12 is a long strip plate and is fixed to one side of the movable plate 10.

[0035] Compared to Example 1, this example adds a more refined fixing mechanism 4. Example 1 relies solely on the structural fit of the mold body 1 to achieve a certain degree of limitation, resulting in a relatively limited fixing effect. During the foaming process, the second mold body 7 may still experience slight displacement due to factors such as foaming pressure, affecting product quality. In contrast, this example enables precise control of the movable plate 10, and through the cooperation of the insertion rod 17 and the insertion hole 13, it provides a more secure limitation and locking of the second mold body 7, significantly improving the fixing effect. Furthermore, the design of the adjusting wheel 18, the first gear 14, and the second gear 15 provides operators with greater operating space during adjustment, making operation more convenient and faster, and improving work efficiency.

[0036] When the second mold 7 needs to be fixed, the operator rotates the adjusting wheel 18, which drives the first gear 14 to rotate. The first gear 14 transmits the rotation to the second gear 15 through meshing. The second gear 15 then drives the screw 16 to rotate. Since the screw 16 is screwed to the fixed plate 9, the rotation of the screw 16 is converted into its own up and down movement, which in turn pushes the movable plate 10 to slide downward in the groove of the fixed plate 9. When the movable plate 10 slides downward, the insertion rod 17 on its bottom surface gradually inserts into the insertion hole 13 on the extension plate 3. When the insertion rod 17 is fully inserted into the insertion hole 13, the second mold 7 can be limited and locked, ensuring that the second mold 7 is stable in position during the foaming process. When the second mold 7 needs to be released, the operator rotates the adjusting wheel 18 in the opposite direction, and the screw 16 rotates in the opposite direction, driving the movable plate 10 to slide upward. The insertion rod 17 is pulled out from the insertion hole 13, which releases the limitation on the second mold 7, making it easy to pull the second mold 7 out of the first mold 5.

[0037] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
