Further, described sealing ring and heat insulating mattress adopt the low titanium alloy material of thermal conductivity to make.
Design principle:
Flow distribution plate is fixed in flow distribution plate fixed head, and there is the second heating wire that heat can be provided its inside, and can make plastic cement in flow distribution plate runner always in a weighing apparatus temperature state! In flow distribution plate Shang center pad and template, sliding shim coordinates and pushes down flow distribution plate, prevents flow distribution plate and the hot problem of chewing runner joint and leaking glue because of gap.It is identical with flow distribution plate runner hole that heat is chewed runner hole, to ensure that runner inside is without dead angle, also can not produce due to the different problems that the pressure loss occurs of runner hole size! Heat is chewed the precision-fit that protective sleeve and heat are chewed fixed head and carry out small size, can heat be chewed and be positioned on the one hand, the least possible being lost in template of heat that the contact of small size can make heat chew simultaneously.
Chew inside for the heat that is delivered to of the maximum temperature limit of heater, adopted the first heating wire is curled up in heat and chews the mode on body:
1. heat is chewed body and is adopted high-accuracy two-axle interlocking Digit Control Machine Tool processing heating wire groove, and before first heating wire of arranging, calculates by hot analysis mode the thermal balance that whole heat is chewed!
2. the first heating wire is chewed three of bodies with heat and is contacted, and has improved the efficiency of hot transmission, has reduced heat loss, has saved power cost.
3. heat is chewed protective sleeve heat is chewed to integrally closed, has effectively stoped heat to chew heat and has directly been radiated on mould, effectively prevents that heat from chewing the loss of heat.
Heat is chewed point and is adopted the good material of thermal conductivity to make, and coordinates by chewing body large area with heat, heat is chewed to heat and pass to whole heat and chew point, ensures that heat chews tip temperature and meet injection moulding requirement.Heat is chewed sealing ring and is adopted titanium alloy material to make, and reduces the loss that heat is chewed sharp heat.Have certain space because chewing between point and mould, in injection moulding process, plastic cement will be full of whole space, effectively reduce and will chew sharp thermal loss.
Invention advantage:
TOP-TIP medical industry TOP-TIP for medical industry of the present invention, by the point of chewing of special construction, chew and on point, have 2 to 4 points cast gates, can realize side and enter glue, also can realize and vertically enter glue, and each cast gate can product of injection moulding, has met the particular/special requirement of medical product to cast gate, heat is chewed can the multiple products of injection moulding, also greatly reduce die cost.
