When it comes to equipment of the heating device type by means of fluid circulation, in order to heat the area in contact with the part, the heating device must pass through other areas of the mold (especially the walls), resulting in heat losses and high inertia during the heating and cooling cycles
Devices of the heating device type by means of induction or resistance, although allowing some of these drawbacks to be avoided, have other drawbacks, such as a very high energy consumption and can only be used to form such parts with small dimensions and approximately flat shapes
[0005] Such equipment, in addition to being energy inefficient, also complicates the design and manufacture of molds

Embodiment Construction
[0036] exist figure 1 A mold 1 according to one embodiment of the invention is shown in .
[0037] The mold 1 comprises an upper module 2a and a lower module 2b comprising respectively an upper wall 4a and a lower wall 4b defining a chamber 6 between them. It is in this chamber 6 that the material forming the part 8 is molded.
[0038] The mold 1 comprises a temperature regulating device 10 comprising, in the embodiment thus shown, a plurality of heating means in the form of heat aids ("boosters" in English term) 100 .
[0039] Preferably, a plurality of heat aids 100 are arranged on both sides of the chamber 6, in other words heat aids 100 are arranged both in the upper module 2a and in the lower module 2b.
[0040] In another embodiment not shown, it is possible to have the heat booster 100 only in the upper module 2a or only in the lower module 2b.
[0041] exist figure 1 In the embodiment shown, the heat aids 100 are regularly distributed along the upper module 2a and ...

The invention relates to a device for controlling the temperature of a mold (1) for manufacturing a plastic part (8). Said device comprises means (100) for heating the molding surface and including at least one radiation head (112). The heating means (100) include a heat exchange plate (120) made of a heat-conductive material and arranged such as to be in contact with a localized area (130) of the wall (4a, 4b) of the mold (1). The radiation head (112) is capable of controlling the temperature of the heat exchange plate (120) by emitting a beam (114) of rays that is directed toward the heat exchange plate (120). Moreover, the invention relates to a method for controlling the temperature of a mold for manufacturing a plastic part (8).
Description
technical field [0001] The invention relates to a device for regulating the temperature of a mould. Background technique [0002] In the field of motor vehicle construction, in order to manufacture parts made of plastic or composite materials, an injection or compression mold made of metal is generally used, the molding area of which is heated and cooled alternately so that the material contained in the mold Form into the desired shape. [0003] For this purpose, conventional devices for regulating the temperature of the mold generally consist of heating and / or cooling means conducted by means of pressurized hot water, in particular by induction, resistance or by fluid (water, oil, etc.) or gas (pressurized steam) circulation to operate. [0004] Such devices have numerous drawbacks. When it comes to equipment of the heating device type by means of fluid circulation, in order to heat the area in contact with the part, the heating device must pass through other areas of ...
