the molds for forming and cutting preform of composite and the preform forming press therewith and the preform manufacturing system therewith

摘要

The present invention relates to a mold for forming and cutting a composite preform, the mold comprising a lower mold and an upper mold positioned in the lower mold; And the lower cushion portion is formed with a main penetration portion penetrated to allow the lower molding portion to pass therethrough, and the lower molding portion is positioned inside the main penetration portion, And the lower cushion part and the upper surface of the support plate are spaced apart from each other by a predetermined distance and the height of the portion where the lower molding part and the lower cushion part meet is the same or the lower cushion part is further projected, The spring cushion is provided between the spring seat and the lower cushion portion so that both ends of the spring come into contact with the upper surface of the support plate and the bottom surface of the lower cushion portion and the retainer bolt is inserted through the bolt head seat provided on the support plate, And an end portion of the retainer bolt is assembled to be fixed to the lower cushion portion; The upper mold is constituted by an upper pusher portion and an upper molding portion. The upper pusher portion is integrated with the lower portion of the support plate. The upper mold is formed with a main groove on the bottom surface of the upper pusher portion, So that the upper portion of the upper molding portion is spaced apart from the upper surface of the upper portion of the upper molding portion by a predetermined distance, And the retainer bolt is assembled to the female screw of the upper forming part through the respective holes provided in the upper pusher part so that the retainer bolt The upper end of the upper molding part is fixed to the upper molding part, And the upper mold is coupled to the upper mold. When the material including the reinforcing fiber and the thermally-deformable resin film is positioned between the lower mold and the upper mold, And the upper pusher portion is further lowered together with the lower cushion portion to cut the edge of the product, so that the composite preform can be easily manufactured and the productivity is high.
