Abstract
A method for moulding an optical component by means of a mould, at least one moulding station, and at least one cooling station including a cooling space, the method including: a step of moulding a moulded component in a moulding station, a step of transferring this component from this moulding station into the cooling space, keeping the moulded component facing at least one of the mould parts, a step of cooling the moulded component by sending a cooling fluid between the moulded component and the walls of the cooling space, the moulded component being kept some distance from these walls.

Method for moulding an optical component by means of a moulding device comprising a mould comprising:
- two mould parts which close onto one another to close the mould and part from one another in order to open same,
- at least one moulding station comprising a moulding cavity of which the walls are formed by a portion of each of the two mould parts,
- at least one cooling station comprising a cooling space formed between a cooling portion of one of the mould parts and a cooling portion of the other of the mould parts,
- said method comprising a first group of steps comprising:
- a step of moulding a moulded component in the moulding cavity,
- a transfer step, during which the moulded component is transferred from this moulding cavity into the cooling space, while keeping the moulded component facing at least one of the mould parts during this transfer step,
- a cooling step, during which the moulded component is kept some distance away from the cooling portions, the cooling step comprising sending a cooling fluid between the moulded component and the cooling portions.
Mould for an optical component, comprising:
- two mould parts which close onto one another to close the mould and part from one another in order to open same,
- at least one moulding station comprising a moulding cavity of which the walls are formed by a portion of each of the two mould parts, the moulding station comprising elements for injecting a material into the moulding cavity,
- at least one cooling station comprising a cooling space formed between a cooling portion of one of the mould parts and a cooling portion of the other of the mould parts,
- wherein the cooling station comprises holding elements allowing the moulded component to be held some distance from the cooling portions when the mould is closed, and comprises elements for injecting a cooling fluid into the cooling housing.
