Abstract:
A mounting block for attaching a cartridge heater to an injection nozzle of a die casting machine, the mounting block comprising: a casing formed from a first, high-strength material; a quantity of a second material at least partially encased within the casing and extending along a first axis of the block, the second material having a thermal conductivity greater than that of the first material; a nozzle receiving hole formed through the block along a second axis of the block generally perpendicular to the first axis and passing through the quantity of second material such that the second material forms at least a portion of an inner surface of the nozzle receiving hole; and a heater cavity extending into the block parallel to the first axis adjacent the quantity of second material and having an end adjacent the nozzle receiving hole, the second material forming at least a portion of an inner surface of the heater cavity, whereby the second material forms a heat conductive path between the heater cavity and the nozzle receiving hole.
