Abstract
Method for molding a multi-component manufactured product through injection of plastic materials in a mold comprising on the inside one or more movable parts, characterized in that the movable parts are moved into a first configuration in which at least two distinct mold cavities are made in the mold, plastic material is injected into each of the two distinct mold cavities to form two components of the manufactured product, the movable parts are moved into a second configuration, in which they make at least a third cavity in the mold the walls of which at least partially consist of the two components already injected, plastic material is injected into the third mold cavity to form a third component of the manufactured product that is thus welded to the first two.

A method for injection molding of a manufactured product in a mold, the manufactured product comprising a plurality of components, the mold comprising a plurality of parts, the plurality of parts comprising at least one mobile part, the method comprising the steps of:
- (a) moving the at least one mobile part into a first configuration;
- in the first configuration, the at least one mobile part comprising at least two distinct mold cavities;
- (b) injecting plastic material into the at least two distinct mold cavities to form at least a first and a second component of the plurality of components;
- (c) moving the at least one mobile part integrally and simultaneously into a second configuration;
- in the second configuration, the plurality of parts comprising at least a third mold cavity, wherein the at least third mold cavity is defined at least partially by respective surfaces of the at least first and second component;
- and
- (d) injecting plastic material into the at least third mold cavity to form at least a third component of the plurality of components so that a portion of a top surface of the at least third component matching a portion of a top surface of the first component, the third component being brought up to the second component;
- wherein in step (c) as the at least one mobile part moves from the first configuration to the second configuration, the at least one mobile part supports and moves the first component.
A mold for injection molding of a manufactured product comprising a plurality of components, the mold comprising:
- a plurality of parts, the plurality of parts comprising at least one mobile part, the mobile part being movable from a first configuration to a second configuration to form a plurality of mold cavities to permit injection molding of plastic material to sequentially form the plurality of components;
- wherein in the first configuration, the plurality of parts comprise at least two distinct mold cavities for molding at least a first and a second component of the plurality of components;
- wherein in the second configuration, the plurality of parts comprise at least a third mold cavity for molding at least a third component of the plurality of components, the at least third cavity being in communication with the at least two mold cavities or the at least two of the corresponding components;
- wherein a portion of the first component is a base onto which the at least third component is molded, the third component being brought up to the second component;
- wherein as the at least one mobile part moves from the first configuration to the second configuration, the at least one mobile part supports and moves the first component.
