Cooling water enters water flow space 31 from the first watercourse port 41, and cooling water takes away cooling during flowing in water flow space 31
The heat of layer 34 lateral wall of ontology, then be discharged by the second watercourse port 42, specifically, the first watercourse port 41 and the second watercourse port
42 be strip shape gob, and the first watercourse port 41 and the second watercourse port 42 are arranged each along the short transverse of adhesive layer ontology 44,
So set, entrance that cooling water can be made more uniform and water flow space 31 is discharged to；Cooling water channel 43 is set to sealing
The bottom of layer ontology 44, specifically, cooling water channel 43 is annular shape, cooling water channel 43 is surrounded on the output end of hot mouth 1, this structure
Being arranged can make cooling water channel 43 preferably cool down to the output end of hot mouth 1；Cooling water channel 43 respectively with the first water channel
Mouthfuls 41 and second watercourse port 42 be connected to, the cooling water entered from the first watercourse port 41 is introduced into cooling water channel 43, then from the
The discharge of two watercourse ports 42；The bottom of cooling layer ontology 34 is set in cooling water channel 43, and is bonded with the bottom of adhesive layer ontology 44；
First sealing ring 32 specifically between 34 bottom of cooling layer ontology and the inner ring of the close hot mouth 1 of cooling water channel 43, passes through
The sealing of first sealing ring 32 avoids cooling water and enters inside hot mouth 1.
Multiple reference Fig. 2, further, the bottom of the second fixed station 33 is equipped with the second sealing ring 331, the second sealing ring 331
It prevents cooling water from leaking outside, and extraneous sundries is avoided to enter hot mouth department set.
Again referring to Figures 1 and 2, further, the side wall of the second fixed station 33 offers anti-indexable 332, anti-indexable 332 and uses
In preventing three layers of hot mouth department set because of rotation caused by water flow.
Again referring to Figures 1 and 2, further, three layers of hot mouth departments set further include anti-rotation pin 5, and anti-rotation pin 5 is set to anti-rotation
Position 332 forms to anti-indexable 332 and limits.
To sum up: reducing the heat transfer speed of hot mouth 1 by the setting of thermal insulation layer 2, optimized by the setting of cooling layer 3
Contact area when the cooling hot mouth 1 of water flow space 31, is not in local mold core excessive temperature differentials phenomenon in injection moulding process, avoids
There is situations such as cast gate cold glue, sun spot, the bright print of cast gate and surface gas line, and cooling velocity is fast, shortens the cold of mold
But the time, to reduce the subsequent injection molding cost of mold.
