Title:
INDUCTION HEATING DEVICE FOR MOULDING PARTS WITH SMALL DIMENSIONS
Document Type and Number:
WIPO Patent Application WO/2022/157275
Kind Code:
A1
Abstract:
The invention relates to a mould which is suitable for moulding parts with small dimensions, and which comprises a frame suitable for being mounted on the plate (101, 102) of a press, the frame comprising a recess for receiving an insert; an insert being configured to be incorporated into the frame, the insert comprising a recess for a die comprising a moulding surface (121, 122) of the part to be moulded; a device for heating the die, the device comprising a gauge rod (131, 132) made of a material which is sensitive to induction heating, the gauge rod being mounted in the insert (350) and one end of said gauge rod being in contact with the die, the moulding surface (121, 122) being substantially centred relative to the gauge rod, a coil (141, 142) being made of a conductive material and surrounding the gauge rod, the coil being connected to a high-frequency alternating current generator (151, 152) such that when it is electrically powered, it generates an induced current in the gauge rod (131, 132), which heats the gauge rod by induction, the gauge rod transmitting the heat to the die, and the external diameter of the gauge rod being greater than or equal to the external diameter of the perimeter defining the external dimensions of the moulding surface (121, 122).
