The mold for molding a composite shoe sole according to claim 7, wherein: drive assembly (7) set up in actuating lever (71) of lower mould (2) and rotate through pivot (73) and set up in lever (72) of lower mould (2) including vertical slip, the one end of lever (72) is stretched out lower mould (2), the other end and is articulated with actuating lever (71), actuating lever (71) butt sets up under card (6).

9. The mold for molding a composite shoe sole according to claim 7, wherein: locking Assembly (8) distribute along vertical direction has the multiunit, every group locking Assembly (8) all include horizontal slip set up in locking lever (81) of lower mould (2), be fixed in locking lever (81) and keep away from briquetting (82) of card (6) one side and set up reset spring (83) between briquetting (82) and lower mould (2), set up activity groove (24) that the level extends and communicate with shaping groove (21) on the outer wall of lower mould (2), locking lever (81) slide and set up in activity groove (24), reset spring (83) are used for driving locking lever (81) and shift out shaping groove (21), locking groove (61) with locking lever (81) interference fit is seted up to the side of card (6).

10. The use method of the mold for molding a composite shoe sole according to any one of claims 1 to 9, wherein: comprises the following steps of (a) carrying out,

s1, vertically moving the driving rod (71) by using the lever (72) and pushing the pattern plate (6) until the locking groove (61) on the pattern plate (6) is aligned with the locking rod (81) of one group of locking assemblies (8), and embedding the locking rod (81) of the locking assembly (8) into the locking groove (61), thereby realizing the positioning of the pattern plate (6);

s2, placing the sole raw material above the pattern plate (6), and pushing the baffle (5) to the second chute (34) by using the moving rod (51) so that the baffle (5) shields the through hole (32) and a second molding cavity is formed between the baffle (5) and the lower die (2);

s3, firstly, placing sole raw materials different from those in the step S2 above the baffle (5), and then enabling the upper die (1) to be abutted against the middle cover (3) so as to form a first forming cavity between the upper die (1) and the baffle (5);

s5, pushing the baffle (5) to the first chute (33) by using the moving rod (51) to enable the baffle (5) to move out of the through hole (32); separating the upper die (1) from the middle cover (3); then the lower die (2) and the middle cover (3) are assembled on a punching machine, so that the upper sole and the lower sole are pressed in a compounding manner by utilizing a pressing block (82) which moves vertically in the punching machine.
