The utility model provides a preforming die and a forming device. The pre-forming mold comprises a first mold, a second mold, a separator, a first insert block and a second insert block. The first mold and the second mold are buckled to form a mounting cavity and a pre-forming cavity which communicate with each other. The separator divides the pre-molding cavity into a first channel and a second channel. The first insert block is arranged in the mounting cavity and provided with a third channel communicating with the first channel and a fourth channel communicating with the second channel. The second insert block is arranged on the side, close to the inlet end, of the pre-forming cavity and provided with a fifth channel communicating with the first channel and a sixth channel communicating with the second channel. In this way, when fiber yarn penetrates through the pre-forming mold, the first insert block and the second insert block can prevent the fiber yarn from entering a gap between the first mold and the
