B) at removable mould bases 3, replaceable mould bases 5 with fixedly have on the mould bases 8 along the horizontal cylindrical deep trouth of die casting copper liquid direction with perpendicular to the cylindrical deep trouth of vertical cylindrical deep trouth of die casting copper liquid direction, electrically heated rod 15,18 embeds respectively in the cylindrical deep trouth; Wherein the deep trouth in removable mould mould bases 3 centers and removable die insert 4 contact portions can directly lead to removable die insert 4, with directly touching removable die insert 4 in heating rod 15, the 18 embedding deep trouths, realize heating simultaneously the mode of heating of mould bases and mould; Heat jointly with vertical heating rod 15,18 the crooked wire rod formula heater 23 equidistant mould bases inside that are embedded in.
Heater divides 23 two kinds of high density cartridge heater 15,18,21,24 and crooked wire rod formula heaters.
The mounting means difference (as shown in Figure 4 and Figure 5) of above-mentioned heater is also different to the requirement of heater etc.:
A) the horizontal mounting means electrical efficiency height of high density cartridge heater, can to the part of inserting the high density cartridge heater be set neatly by the thermal field situation by moulding, this mounting means has proposed very high heatproof requirement to the heater wire of high density cartridge heater simultaneously, because this mounting means must be embedded in the heater wire of heater in the wire casing of mould bases.Owing to above reason; laterally the heater wire of the employed heater of mounting means is a kind of high temperature resistant glass line; heatproof can reach 800 ℃, simultaneously for the better protection lead, also must wrap up with a kind of high temperature resistant sleeve pipe (750 ℃) outside the heater wire of heater.
B) vertical mounting means of high density cartridge heater: such mounting means electrical efficiency is on the low side, because the high density cartridge heater can't be installed in some special region.But such mounting means requires lowly to the heater wire of high density cartridge heater, because heater wire exposes in air, is not embedded in the mould and goes, and can save cost widely.Simultaneously, such mounting means is convenient especially to damage replacing to the high density cartridge heater, changes electric heater the horizontal mounting means and must unload mould down from machine and need not resemble.
Prove that by experiment it is best mounting means that the high density cartridge heater uses the mixing mounting means of horizontal mounting means and vertical mounting means combination to come preheated mold, can obtain mold temperature field uniformly.Prove by experiment that simultaneously the Hybrid Heating mode of using mould and mould bases to heat simultaneously is a best mode.
