Mold and method for forming plastic products

A mold for manufacturing plastic products provided with a bottom and a sidewall, wherein the mold comprises at least a first and second mold part which jointly define at least partly at least one mold cavity and are movable in a first direction, wherein the at least one mold cavity comprises at least one bottom-forming part and one side wall-forming part, wherein on the first mold part at least one fixed wall part is provided which supports a first movable wall part which is movable relative to the respective fixed wall part in at least a second direction which includes an angle with the first direction, wherein in said first movable wall part a second movable wall part is provided, on the side facing the mold cavity, and wherein the second movable wall part is movable within the mold cavity between a forwardly moved position and a retracted position relative to the first movable wall part, and wherein the mold cavity has a first volume when the mold is in a closed position and the second movable wall part is in the refracted position, and wherein the mold cavity has a second volume when the mold is in the closed position and the second movable wall part is in the forwardly moved position, the second volume being less than the first volume, the second movable wall part being movable within the mold cavity when the mold is in the closed position for displacing plastic introduced into the mold cavity to fill the entire mold cavity with plastic.

A mold for manufacturing plastic products provided with a bottom and a sidewall, the mold including a first mold part and a second mold part, the first mold part and the second mold part being movable in a first direction between an open position and a closed position, the first mold part and the second mold part defining a mold cavity when in the closed position, wherein the first mold part comprises:

• a fixed wall part fixed to the first mold part and having an inclined surface with respect to the first direction;
• a first movable wall part supported on the inclined surface of the fixed wall part, the first movable wall part being movable within the mold cavity along the inclined surface relative to the fixed wall part in a second direction, the second direction being disposed at an angle with respect to the first direction;
• and
• a second movable wall part supported within the first movable wall part and facing the mold cavity, the second movable wall part being movable within the mold cavity in a third direction between a forwardly moved position and a retracted position relative to the first movable wall part when the first mold part and the second mold part are in the closed position, wherein the mold cavity has a first volume when the mold is in the closed position and the second movable wall part is in the retracted position, and wherein the mold cavity has a second volume when the mold is in the closed position and the second movable wall part is in the forwardly moved position, the second volume being less than the first volume, the second movable wall part being movable within the mold cavity for displacing plastic introduced into the mold cavity to fill the entire mold cavity with plastic.
