Special-shaped adapter integrated forming die and method

Abstract

The invention provides a special-shaped adapter integrated forming die. The special-shaped adapter integrated forming die comprises a bottom plate, wherein a die frame is vertically and fixedly connected to the bottom plate, an upper die is rotatably fixed in the middle of the die frame, and the upper die, the die frame and the bottom plate form a hollow cavity; the top face of the upper die is parallel to the plane of an adapter guide rail groove to be formed, and the top face of the upper die is not parallel to the upper surface of the bottom plate. The invention further provides a special-shaped adapter integrated forming method. According to the forming die, various dimensional precision requirements and functional requirements of an adapter are ensured, and the economical efficiency and the practicability are high; a polytetrafluoroethylene film is effectively prevented from falling off, and the integrity of the adapter is ensured; not only is the effective sliding of the adapteron the guide rail surface ensured, but also the requirements of wear resistance, high temperature resistance and adhesion resistance are met; the positioning requirement is guaranteed, the inclined drawing design is met, and the structure and function integrated design is met; and the requirements of economical efficiency, manufacturability, practicability and operability of die design are met.

Description

technical field [0001] The invention relates to an integral molding mold and method for a special-shaped adapter. Background technique [0002] As an important part of the aircraft ejection device, the adapter is the connection and support device between the aircraft and the ejection device. Its main function is to slow down the impact and vibration of the aircraft due to overload during the storage, lifting, transportation and ejection of the aircraft. , which plays a guiding role when the aircraft is ejected. In recent years, through continuous development, in order to adapt to different platforms, adapter materials have continued to progress. The materials used mainly include rubber (such as natural rubber, nitrile rubber, butyl rubber, ethylene propylene rubber, neoprene, etc.), Polyurethane elastomer, polyurethane foam and other materials or a mixture of the above materials. Judging from the relevant literature, polyurethane elastomers and polyurethane foams are the m...

AI Technical Summary

Problems solved by technology

The adapter structure has also developed in a variety of ways, and the processing and forming methods are also different. At present, there is no ready-made solution to solve the forming problem of some special-shaped adapters, which can meet the functional requirements of the adapter and improve the performance at the same time.
