At present, the forming method based on the autoclave process in the industry is mainly metal core mold forming or soft mold auxiliary metal mold forming. When the soft mold assists the metal mold in molding, the original end head packaging scheme is that rubber and sealing rubber strips are filled between the soft mold and a metal molding tool to achieve the purpose that the soft mold is connected with the metal tool, and the soft tool is prevented from deforming. However, when the method is used for filling the gap between the flexible mold and the metal tool, a large amount of sealing rubber strips and rubber are consumed, and the price of the two materials is high, so that cost reduction and efficiency improvement are not facilitated; the rubber blocks used in the method cannot be effectively kept flush with the metal tooling bottom plate, so that the deformation of the soft die is easily caused, and the scrap risk of the soft die and parts is increased; in addition, the soft die for forming the I-beam is a soft long and thin cylindrical workpiece made of composite materials, rubber and sealing rubber strips are filled between the soft die and the metal tool, and if the sealing rubber strips are not filled fully, the sealing rubber strips are easily broken through by pressure to form a channel under the influence of pressure to generate the condition of explosion bags when the sealing rubber strips are cured and pressed, so that the parts are unqualified in production. Therefore, an effective method for encapsulating the terminals is needed to solve the problems of deformation of the flexible mold and cost reduction.
