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 (2), a second part (4), and a third part (6), as well as a guide (20, 22, 26, 28) allowing relative movement of the first part (2) with respect to the third part (6) and relative movement between the second part (4) and the third part (6), a first parting surface being defined between the first part (2) and the third part (6) and a second parting surface being defined between the second part (4) and the third part (6), the mold able to be placed in a so-called open position where the first parting surface and the second parting surface are open, meaning that the corresponding parts of the mold are spaced apart from one another, and a so-called closed position where the first parting surface and the second parting surface are closed, meaning that the corresponding parts of the mold come into contact with one another,

• wherein each parting surface comprises at least one mechanical stop (44;
• 50;
• 62) that is movable between a first position, or operative position, where said stop prevents the mold from reaching its closed position by defining a predetermined spacing for each parting surface between the corresponding parts of the mold, and a second position, or retracted position, where the mold can reach its closed position.
