Description

Technical Field

[0001] This utility model relates to the field of composite material molding die technology, and in particular to an integrated molding die for a projectile wing. Background Technology

[0002] As a crucial component of a missile, the fins effectively provide lift, influencing the missile's range, maximum altitude, and maneuverability. For instance, the fin design of a cruise missile can provide approximately 80% of its lift, necessitating a lightweight design. As a key component ensuring the missile's critical tactical performance, fin design is of paramount importance.

[0003] Therefore, composite material wings will play a crucial role. However, the design and manufacturing of composite material compression molding molds are relatively complex, and the products are easily restricted by the cavity during the mold opening process, making demolding difficult. An unreasonable mold structure design will cause uneven pressure on the molded products and poor internal quality. Therefore, it is urgent to design molding molds to ensure the production quality and efficiency of wings.

[0004] Therefore, it is necessary to design an integrated mold for the missile wing to solve the above problems. Utility Model Content

[0006] The technical solution of this utility model is: an integrated mold for a missile wing, including an upper mold and a lower mold; the upper mold has an upper cavity; the lower mold has a lower cavity; after the upper mold and the lower mold are closed, the upper cavity and the lower cavity form a missile wing cavity with one end open.

[0007] The lower mold has centrally symmetrical guide members at both ends; the upper mold has guide holes that cooperate with the guide members; the guide members include guide posts and guide sleeves sleeved on the guide posts; a number of steel balls that roll and cooperate with the guide holes are evenly distributed on the outer circumferential surface of the guide sleeves.

[0008] The upper mold has downwardly protruding positioning bosses arranged in a matrix on its edge; the lower mold has positioning grooves corresponding to the positioning bosses, and the two sides of the positioning bosses and the positioning grooves are in contact with inclined surfaces.

[0009] The lower mold is provided with overflow grooves symmetrically arranged on both sides of the lower cavity along the length of the lower cavity.

[0010] The lower cavity is fitted with a release module; the release module is locked to the lower mold by a locking screw at the bottom of the lower mold; the bottom of the release module is provided with a push rod that penetrates the lower mold.

[0011] Temperature measuring holes that communicate with the wing cavity are evenly distributed on both sides of the upper and lower molds.

[0012] The lower mold has an exhaust port that communicates with the wing cavity at the end away from the opening of the wing cavity.

[0013] The lower mold has a positioning post at one end of the wing cavity opening that mates with the wing handle.

[0035] Furthermore, the upper mold 1 has downwardly protruding positioning bosses 1-2 arranged in a matrix on its edge; the lower mold 2 has positioning grooves 2-2 corresponding to the positioning bosses 1-2, and the two sides of the positioning bosses 1-2 and the positioning grooves 2-2 are in inclined contact, which further ensures the mold closing accuracy of the upper mold 1 and the lower mold 2, greatly improving the efficiency of mold opening and closing, thereby improving production efficiency.

[0036] Furthermore, the lower mold 2 is provided with overflow grooves 2-3 symmetrically arranged on both sides of the lower cavity 2-1 along the length of the lower cavity 2-1. These grooves can store excess resin generated during molding, preventing it from flowing from the surface of the assembly block into the top screw hole and the mating surface of the upper and lower molds 2, thus reducing the difficulty of subsequent mold opening and cleaning.

[0037] Furthermore, a demolding module 2-4 is embedded in the lower cavity 2-1; the demolding module 2-4 is locked to the lower mold 2 by a locking screw at the bottom of the lower mold 2; the bottom of the demolding module is provided with a push rod that penetrates the lower mold 2 to facilitate demolding of the product.

[0038] Furthermore, temperature measuring holes 4, which communicate with the wing cavity, are evenly distributed on both sides of the upper mold 1 and the lower mold 2. This allows for the monitoring of the tooling temperature throughout the molding process, ensuring that the molding and curing of the wing strictly follows the set procedure, thereby guaranteeing product quality.

[0039] Furthermore, the lower mold 2 is provided with an exhaust hole 2-5 at the end away from the opening of the wing cavity, which is connected to the wing cavity.

[0040] Furthermore, the lower mold 2 is provided with a positioning post 2-6 at one end of the open cavity of the missile wing, which cooperates with the wing handle. The positioning post 2-6 cooperates with the wing handle to ensure the positioning of the product. The forming mold also serves as an assembly tooling, so the missile wing can be formed in one piece, eliminating the assembly process and greatly improving the production efficiency of the product.

[0041] Furthermore, the upper mold 1 and the lower mold 2 are provided with secondary processing reference surfaces 5 at the four corners of the projectile, which provide a reference for secondary processing for product updates and iterations, reduce the cost of secondary tooling material feeding, and can also quickly complete the feedback of updates and iterations to ensure subsequent product delivery.

[0043] In this embodiment, the integrated molding mold for the missile wing uses an upper mold 1 and a lower mold 2 to form a missile wing cavity with one open end after they are closed. The aerodynamic shape of the missile wing is used as the forming surface of the mold, which can ensure the smoothness of the aerodynamic shape of the missile wing. At the same time, the mold structure design is optimized, the number of parts is reduced, and the possibility of defects caused by assembly processes such as gluing and mechanical connection is avoided. This effectively reduces the weight of the missile wing and improves its load-bearing capacity.
