Mold and method for preparing fiber composite material part with V-shaped opening structure

The invention discloses a mold for preparing a fiber composite material workpiece with a V-shaped opening structure, which comprises an upper mold and a lower mold, the upper mold and the lower mold form a cavity of a transverse part of the workpiece with the V-shaped structure, and the lower mold comprises a lower mold main body and a detachable sliding block. The detachable sliding block is installed on the lower die body and corresponds to a deep part (longitudinal bending part) of a workpiece, and the detachable sliding block and the lower die body form a deep part (longitudinal bending part) cavity of the workpiece of a V-shaped structure. And the problems of disordered lines, product scrapping and the like caused by bridging, bag explosion and the like of the vacuum bag in the product forming process can be effectively solved. 本发明公开了一种用于制备V型开口结构纤维复合材料制件的模具，包括上、下模具，所述上模和下模构成V型结构制件横向部分的型腔，所述下模具包括下模具主体以及可拆卸滑块，所述可拆卸滑块安装在下模具主体对应制件进深部分（纵向弯折部分），与下模主体构成V型结构制件的进深部分（纵向弯折部分）型腔，在制备具体制件时，通过在纵向型腔塞入随形膨胀块，可以有效解决产品成型过程中
