Detailed description of the invention
This utility model provides the hot mouth of a kind of anti-melten gel degraded, for making the purpose of this utility model, technical scheme and effect
Fruit is clearer, clear and definite, further describes this utility model below.Should be appreciated that described herein being embodied as
Example, only in order to explain this utility model, is not used to limit this utility model.
Refer to Fig. 1, for the structural representation of the hot mouth of anti-melten gel described in the utility model degraded, described anti-melten gel
The hot mouth of degraded, including hot mouth body, wherein, described hot mouth body is provided with runner 101, heater 102 and nozzle point 103,
Described nozzle point 103 is arranged on runner 101 bottom, and described nozzle point 101 has certain gap, in institute with mould or die junction
The outer surface stating nozzle point 101 is provided with thermal insulation layer 104, and described thermal insulation layer 104 reduces the internal heat with nozzle point outside 103 of nozzle point 103
Exchange.
Hot mouth transfers heat to nozzle point, and in hot mouth runner, melten gel flows to cast gate, owing to depositing between nozzle point and mould die
In gap, melten gel will enter gap, contact with nozzle point contact surface, die contact surface, and die contact surface is cold because being distributed in die
But water route temperature is substantially reduced, and is not easily caused melten gel degraded.And at nozzle point contact surface, common nozzle point is full copper product, heat energy
Well being delivered to each surface, the temperature of nozzle point contact surface temperature and hot mouth runner inner wall is not lost, and gap melten gel is resident
In time hotter mouth runner, melten gel is the longest, and degraded occurs in melten gel, causes the jaundice of cast gate peripheral compound, blackout, of the present utility model
The hot mouth of described anti-melten gel degraded, for drawbacks described above, the outer surface at nozzle point is provided with thermal insulation layer, due to nozzle point and mould or mould
Having certain gap between core, in use, melten gel can enter in gap, owing to being provided with thermal insulation layer at nozzle point outer surface, therefore,
The outside melten gel near nozzle point of nozzle point is formed without heat exchange inside nozzle point, and therefore, the melten gel at nozzle point can cool down, no
Can degrade, therefore, be not result in cast gate periphery jaundice blackout.
Further, the hot mouth of described anti-melten gel degraded, wherein, described thermal insulation layer 104 is wrapped in institute for heat-barrier material
State and constitute on nozzle point 103 outer surfaces.The hot mouth of described anti-melten gel of the present utility model degraded, preferred embodiment, described thermal insulation layer
Use heat-barrier material to be wrapped in molding on nozzle point outer surface, when effect of heat insulation is the best, material coating can be thermally shielded again, it is possible to
It is used for multiple times, it is ensured that effect of heat insulation, conventional insulation material, such as glass fibre, asbestos, rock wool, silicate etc., Novel heat insulation material
Material, such as aerogel blanket, evacuated panel etc., user can choose different heat-barrier materials according to different demands and make thermal insulation layer.
Further, the hot mouth of described anti-melten gel degraded, wherein, described thermal insulation layer 104 is made for heat-barrier material, inlays
On described nozzle point 103.Another preferred embodiment of the hot mouth of described anti-melten gel of the present utility model degraded, described thermal insulation layer can
