Abstract
The invention concerns an injection overmoulding device comprising at least one indexed rotary turret on which cooled moulds are installed, each mould comprising a plurality of cavities, and at least five stationary stations arranged around said turret, including at least a first station, a second station and a third station that are used, respectively, for carrying out the operations of positioning the inserts in the cavities of the mould, injecting plastic material into the cavities of the mould, and demoulding the at least partially cooled objects. The device comprises, for each mould, at least separate injection means. The invention also concerns a method implemented by the device.

An injection overmolding device for forming molded objects comprising:
- an indexed rotary turret having a plurality of cooled molds, each cooled mold including a plurality of cavities;
- an injection device for each cavity;
- and
- a plurality of operational stations arranged around the indexed rotary turret,
- wherein the plurality of operational stations include,
- a first operational station for positioning an insert into at least some of the cavities of one of the plurality of the cooled molds,
- a second operational station for injecting plastic material into at least some of the cavities of one of the plurality of the cooled molds having the inserts for forming the molded objects with the inserts, and
- a third operational station for removing the at least partially cooled and molded objects with the inserts formed in the least some of the cavities.
A method for injection overmolding carried out on an indexed rotary turret, the method comprising the steps of:
- positioning prefabricated inserts into the cavities of the mold;
- closing the mold;
- locking the mold by a separate forced closing mechanism to the cavities of the mold;
- injecting a plastic material into each cavity;
- solidifying a gate;
- blocking an injection threshold;
- releasing the forced closing mechanism of the mold;
- compacting the mold;
- cooling the mold;
- unlocking the mold and ending the compacting of the mold;
- opening the mold;
- and
- unloading the molded objects including the inserts from the mold.
