Abstract
Method for moulding a multi-component manufactured product through injection of plastic materials in a mould comprising on the inside one or more movable parts, characterised in that the movable parts are moved into a first configuration in which at least two distinct mould cavities are made in the mould, plastic material is injected into each of the two distinct mould 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 mould the walls of which at least partially consist of the two components already injected, plastic material is injected into the third mould cavity to form a third component of the manufactured product that is thus welded to the first two.
Claims13
Mould (S) to be used to mould a multi-component manufactured product (10) through injection of plastic materials and comprising on the inside one or more mobile parts (30, 32, 50), characterised in that the mobile parts are movable
- into a first configuration, in which they make at least two distinct mould cavities (22, 24) in the mould for at least a first and a second component (12, 14), and
- into a second configuration, where, once it has been achieved, they make at least a third cavity (26) in the mould for at least a third component (16), said third cavity (26) communicating with the other cavities (22, 24), all or at least two of the corresponding components (12, 14, 16) of the manufactured product being able to be made by successive injection in each of said cavities,
- wherein the first component (14) in one of its parts (14b) acts as a base for the third component (16) that is in turn brought up to the second component (12).
Method for moulding a multi-component manufactured product (10) through injection of plastic materials in a mould (S) comprising on the inside one or more movable parts, characterised in that
- the movable parts (30, 32, 50) are moved into a first configuration in which they make at least two distinct mould cavities (22, 24) in the mould,
- plastic material is injected into each of the two distinct mould cavities to form two components of the manufactured product (12, 14a, 14b),
- the movable parts are moved integrally and simultaneously into a second configuration, in which they make at least a third cavity (28) in the mould the walls of which at least partially consist of the two components already injected,
- plastic material is injected into the third mould cavity to form a third component (16) of the manufactured product that is thus welded to the first two.
