Abstract
The present disclosure relates to a device for the injection molding of an item including at least one face, a protruding peripheral part provided with an edge for the connection with another face, said device including mold elements movable with respect to each other and jointly cooperating by delimiting therebetween joint planes as well as a cavity intended to be filled with liquid plastic material through injection channels to form said item after the ejection from the mold, characterized in that it includes a mold element to form the protruding part of the item, whose joint plane with the immediately adjacent front mold element is angularly oriented from said edge and on at least a portion of the length thereof, according to the direction of ejection.
Claims11
A device for the injection molding of an item, the device comprising, on at least one face, a protruding peripheral part provided with an edge for the connection with another face, said device including mold elements movable with respect to each other, and jointly cooperating by delimiting therebetween joint planes as well as a cavity intended to be filled with a liquid plastic material through injection channels to form the item after ejection from the mold, and a mold element to form the protruding part of the item whose joint plane with the immediately adjacent front mold element is angularly oriented from the edge and on at least a portion of the length thereof according to the direction of ejection.
A method for producing an item including at least a protruding peripheral part provided with an edge for the connection of a front face thereof, the method using an injection molding device comprising moving mold elements with respect to each other, and jointly cooperating by delimiting therebetween joint planes as well as a cavity filled with a liquid plastic material through injection channels to form the item after ejection from the mold, and forming the protruding part of the item in one of the mold elements whose joint plane with an immediately adjacent front one of the mold elements is angularly oriented from the edge and on at least a portion of the length thereof according to the direction of ejection.
