The pull rod 14 drives the second limiting rod 13 to move in the direction away from the third limiting rod 16. When the pull rod 14 passes through the two limiting cavities 17, under the action of the tension of the two third springs 18, one end of the two third limiting rods 16 Both limit cavities 17 are extended out and inserted into the positioning grooves 22 of the upper mold core 3 respectively, and the upper mold core 3 and the lower mold core 25 are fixed together with the positioning plate 4. At this time, the second limit rod 13 abuts against the third limit rod 16, and the second spring 12 is in a compressed state. The lower mold core 25 is fixed by the same operation, and the corresponding shoe sole material is injected into the lower mold core 25, and then the two bottom molds 1 are closed, and the plug block 26 of one bottom mold 1 is inserted into the slot 23 of the other bottom mold 1. When the two bottom molds 1 are closed, the pull rod 14 is inserted into the limit groove 11 of the other bottom mold 1, and the two bottom molds 1 are fixed together with the plug block 26 to prevent displacement. When the upper mold core 3 and the lower mold core 25 need to be replaced, the first limiting rod 8 is pushed inward into the slide groove 24, the positioning plate 4 is slid away from the upper mold core 3, the limiting block 10 leaves the positioning groove 22, the cross bar 15 is pulled outward, and the third limiting rod 16 is separated from the upper mold core 3 and the limiting groove 11 in turn. The third limiting rod 16 does not contact the second limiting rod 13. The second limiting rod 13 moves to the other end of the limiting groove 11 under the action of the second spring 12, and the cross bar 15 is released. The two third limit rods 16 abut against the second limit rod 13, and the handle 20 is rotated to make the two sliders 7 move toward each other. The inclined surfaces on the two sliders 7 abut against the inclined surfaces of the upper mold core 3, and the two sliders 7 simultaneously push the upper mold core 3 to move away from the groove, thereby taking out the upper mold core 3, and taking out the lower mold core 25 according to the taking-out operation of the upper mold core 3, and putting another style of upper mold core 6 and lower mold core 25 into the placement groove 2 respectively, and fix the limit component and positioning plate 4 according to the same operation to complete the replacement.
