Embodiment 1

[0049] Such as Figure 1 ~ Figure 3 As shown, the mold for forming the guide rail of the composite launch box includes a lower mold 2 and an upper mold 1 which are arranged oppositely. The lower mold 2 is provided with a guide rail cavity. The bolt assembly 3 is connected, and the pressure generated by the screwing of the bolt assembly 3 causes the guide rail to be formed to be pressurized and solidified in the guide rail cavity.

[0050] The lower mold 2 includes a lower mold frame 21 welded by several steel plates, the lower mold frame 21 is provided with a lower mold panel 22, and the working surface of the lower mold panel 22 is processed by a high-precision numerical control machine tool to ensure dimensional accuracy and surface quality, thereby ensuring The molding dimensional accuracy and surface quality of the guide rail. The guide rail cavity is located on the lower mold panel 22 . During processing, after the lower mold panel 22 and the lower mold frame 21 are wel...

Embodiment 2

[0059] Compared with Embodiment 1, this embodiment differs in that, as image 3 , Figure 5 As shown, the two ends of the cavity of the guide rail are provided with end stoppers 5, and the end stoppers 5 are arranged at both ends of the working surface of the lower die for controlling the length of the guide rail and the shape of the end face of the guide rail. The working surface of the lower mold refers to the bottom surface of the molding cavity.

[0060] The end block 5 is installed on the lower die 2 through the block connecting assembly 6. One end of the lower die panel 22 is provided with an insert 4. The block connecting assembly 6 includes a connecting plate 61 and a plurality of fastening screws 62. The connecting plate 61 passes through The fastening screw 62 fixes the end block 5 to one end of the lower mold frame 21 .

[0061] Both ends of the end block 5 and the fixing frame 211 are provided with a plurality of threaded holes, and the threaded holes on the fixi...

Embodiment 3

[0064] Compared with Embodiment 2, this embodiment differs in that, as Figure 8 As shown, both the insert 4 and the end stopper 5 are provided with mirror-image symmetrical parts to realize symmetrical rail molding. Since the guide rails of the launching box are usually symmetrical parts, by designing mirror-image symmetrical inserts 4 and end stoppers 5, it is possible to use one set of molds to form two symmetrical guide rails. Part 4 and end stopper 5 to form another symmetrical guide rail. The end block 5 and the insert 4 are threadedly connected to the connecting piece, the screw and the lower die.

Abstract

The invention provides a composite material launching box guide rail forming mold and a guide rail forming method.The guide rail forming mold comprises a lower mold, an upper mold, an insert and a bolt assembly, the lower mold is provided with a guide rail cavity, the upper mold is formed by splicing multiple sections, and the multiple sections of upper mold are connected with the lower mold through the bolt assembly; pressure generated by connection of the bolt assembly enables the guide rail to be formed to be pressurized, cured and formed in the guide rail forming mold cavity. By means of the guide rail forming die, the forming size precision, the surface smoothness and the material compactness of the launching box guide rail can be effectively guaranteed, and high-precision and ultra-slenderness-ratio composite guide rail forming can be economically and efficiently achieved. The guide rail is formed by adopting a resin pre-soaking method pressure forming process method, so that the production efficiency can be remarkably improved, the waste of auxiliary materials is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of forming a launch box guide rail, in particular to a composite material launch box guide rail forming mold and a guide rail forming method. Background technique [0002] The launch box is the core and key of the box-type launch technology. The composite launch box will gradually replace the metal launch box due to its advantages of light weight and excellent corrosion resistance. The guide rail in the launch box is the carrier to ensure the accuracy of the weapon out of the box. In order to meet the angle of the out of the box, the guide rail must have very high surface quality and dimensional accuracy, especially for the height, straightness, and flatness of the working surface of the guide rail. high demands. [0003] The guide rails in composite launch boxes are usually slender parts composed of continuous fiber-reinforced resin-based composite materials on the surface and lightweight filler materials ...
