Apparatus for opening a mold which includes a body section, having an opening and a curled rim, and a closure section, having a lid removably applied to the opening of the body section, a crossbar resiliently urged away from the lid, a first ratchet hingedly connected to the crossbar so as to releasably engage the rim of the body section when the lid of the closure section is applied to the opening of the body section and a second ratchet hingedly connected to the crossbar so as to releasably engage the rim of the body section when the lid of the closure section is applied to the opening of the body section, said apparatus comprising arranging means for arranging the mold such that the body section is above the closure section during the opening of the mold;
- urging means for urging the crossbar of the closure section towards the lid of the closure section;
- first pivoting means for automatically pivoting the first ratchet of the closure section out of engagement with the rim of the body section when the crossbar is urged towards the lid by said urging means;
- second pivoting means for automatically pivoting the second ratchet of the closure section out of engagement with the rim of the body section when the crossbar is urged towards the lid by said urging means;
- first pushing means for pushing a first end of the closure section away from the body section after the first and second ratchets are disengaged from the rim of the body section;
- second pushing means for pushing a second end of the closure section away from the body section after the first and second ratchets are disengaged from the rim of the body section and after the first end of the closure section is pushed away from the body section;
- ejecting means for ejecting an article from the body section after the closure section has been pushed away from the body section by said first and second pushing means;
- catching means movable between a first position in which said catching means catches the closure section after the closure section has been pushed away from the body section by said first and second pushing means and in which said catching means discharges therefrom an article ejected from a previously opened mold and a second position in which said catching means catches the article ejected from the body section by said ejecting means and in which said catching means discharges the closure section caught by said catching means when said catching means was in said first position;
- and moving means for moving said catching means between said first and second positions.
Apparatus for opening a mold which includes a body section, having an opening and first and second coil springs releasably attached to the body section, and a closure section, having a lid removably applied to the opening of the body section and first and second retainers which releasably engage the first and second coil springs, respectively, when the lid of the closure section is removably applied to the opening of the body section, said apparatus comprising arranging means for arranging the body section above the closure section during the opening of the mold;
- pivoting means for automatically pivoting the first and second coil springs out of engagement with the first and second retainers, respectively;
- first pushing means for pushing a first end of the closure section away from the body section after the first and second coils springs are disengaged from the first and second retainers, respectively;
- second pushing means for pushing a second end of the closure section away from the body section after the first and second coil springs are disengaged from the first and second retainers, respectively, and after the first end of the closure section is pushed away from the body section;
- ejecting means for ejecting an article from the body section after the closure section has been pushed away from the body section by said first and second pushing means;
- catching means movable between a first position in which said catching means catches the closure section after the closure section has been pushed away from the body section by said first and second pushing means and in which said catching means discharges therefrom an article ejected from a previously opened mold and a second position in which said catching means catches the article ejected from the body section by said ejecting means and in which said catching means discharges the closure section caught by said catching means when said catching means was in said first position;
- and moving means for moving said catching means between said first and second positions.
