Tandem mold for creating injection-molded parts from synthetic material

A tandem mold for creating injection-molded parts from synthetic material, comprising a first part, a second part, and a third part, as well as a first guide between the first part and the third part;

• the first guide comprising:
• at least one first guide column fixed to the first part and at least one ring fixed to the third part, said at least one first guide column slidable within a corresponding ring, and a second guide between the second part and the third part;
• the second guide comprising:
• at least one second guide column fixed to the second part and at least one ring fixed to the third part, said at least one second guide column slidable within a corresponding ring, a first parting surface being defined between the first part and the third part and a second parting surface being defined between the second part and the third part, the tandem mold having an open position where the first parting surface and the second parting surface are open, in which respective parts of the tandem mold are spaced apart from one another, and a closed position where the first parting surface and the second parting surface are closed, in which the respective parts of the tandem mold come into contact with one another,
• wherein said first and second parting surfaces each comprises at least one mechanical stop that is movable between an operative position, where said at least one mechanical stop, comprising a cylinder attached only to the first part, and a cylinder attached only to the second part, which prevents the tandem mold from reaching its closed position by defining a predetermined spacing for each of said first and second parting surfaces between the respective parts of the tandem mold, and a retracted position, in which the tandem mold assumes its closed position.
