ABSTRACT:
A side core-pulling mechanism of mold includes a slide block, an impacted block and a wobbly block. The bottom of the slide block projects outwards to form a columnar pin. The front surface of the impacted block defines a receiving cavity, a first slot and a second slot. The first slot upright extends downwards to pass through the bottom of the impacted block from the over place of the right end of the receiving cavity and communicates with the right end of the receiving cavity. The second slot extends rightwards and downwards to pass through the bottom of the impacted block from a start end of the first slot. The first and second slots communicate with each other. The columnar pin is movable in the first and second slots. The wobbly block is received in the receiving cavity of the impacted block. The wobbly block is against the bottom wall of the receiving cavity to cut off the first slot at a nature status and rotates upwards in the receiving cavity for making the first slot be in a through status.
