  • the cooling of the mold, and therefore of the part must be determined in such a way that the part, and possibly the mold, are not damaged during the ejection.
  • the patent DE 198 30 025 describes a mold part of which is provided with cooling channels.
  • Licences EP 0 941 788 , US 2,974,379 and WO 96/22852 describe molding machines equipped with cleaning devices of the joint planes and cavities of the molds.
  • the patent DE 10 2006 057660 discloses a molding machine in which such a cleaning device can be used to cool the molded part.
  • a difficulty is the need to obtain a rapid cooling to avoid the risk of crystallization of the material.
  • Another difficulty relates to the risk of deformation of the workpiece resulting from wedging effects of the workpiece in the mold and the forces applied by the ejector, due in particular to the difference between the coefficient of expansion of the mold and that of the workpiece and the fact that the material constituting the part does not exhibit a sudden change in volume during its cooling. Mastering the time cycles of conformation and demolding also poses a difficulty.
  • the patent EP 895 823 discloses a method of molding parts of amorphous materials, wherein the material is deposited in a cavity of a first mold part, and is heated by an electric arc. Then, a second part of the mold is coupled to the first part of the latter to close the mold and shape a part. Finally, the mold is open to extract the shaped part. During these operations, the mold is cooled. There is a great difficulty in managing the temperature of the material to avoid the risk of crystallization.
  • the present invention aims to propose a solution including difficulties above.
  • a method of demolding a workpiece of a material having a glass transition temperature and a melting temperature above its glass transition temperature, formed in a cavity of a mold comprising at least two mold parts delimiting between they this conformation cavity, wherein the mold is maintained at a conformation temperature between said glass transition temperature and said melting temperature.
  • the proposed method comprises opening the mold by spacing said mold parts, the part in the mold cavity being at a temperature between said glass transition temperature and said melting temperature; a local projection of a cooling gas towards the room remaining in a part of mold, and, after a period determined after the start of the projection of the gas, the ejection of the part of this part of the mold, this determined time being such that the part reaches a temperature below its glass transition temperature.
  • the method may include stopping the throwing of the gas before ejecting the part.
  • the method may include ejecting the part during gas spraying.
  • the method may include maintaining the mold at a temperature between the glass transition temperature and the melting temperature of the workpiece material.
  • a method of shaping a workpiece into a material having a glass transition temperature and a melting temperature above its glass transition temperature which comprises the aforementioned demolding process and, previously, the setting of a quantity of material at a temperature between its glass transition temperature and its melting temperature and injecting that amount of material in that state into said shaping cavity when the mold parts are coupled to conform the material to the shape of the conformation cavity.
  • a method of shaping a workpiece into a material having a glass transition temperature and a melting temperature greater than its glass transition temperature which comprises the aforementioned demolding process and, previously, the introduction of an amount of material in a recessed portion of one of the mold portions, and coupling the mold portions to die-stamped the material to the shape of the conformation cavity.
  • a molding machine for carrying out the proposed method, which comprises a mold comprising at least a first and a second mold part delimiting between them, when they are coupled, a conformation cavity of a part in a material having a glass transition temperature and a melting temperature above its transition temperature glassy; means for maintaining the mold at a temperature between said glass transition temperature and said melting temperature; at least one ejection means for extracting the workpiece from one of said mold parts; and at least one gas spray nozzle having at least one exit orifice, said spray nozzle being mounted on displacement means able to move the nozzle between a withdrawal position in which the mold parts can be mated or spaced apart and an advanced position in which, when the mold parts are spaced apart, the outlet orifice of the nozzle is placed towards and in the vicinity of the piece remaining in a mold part; and a control means for controlling the opening of the mold, then feeding the nozzle into said advanced position and injecting the cooling gas, and then ejecting the workpiece after a determined delay following the start of the
