The utility model discloses simple structure, it is little influenced by mould structure, and the suitability is strong, and the cooling effect is good, can effectively eliminate the gas pocket and the shrinkage cavity on die casting surface, improves product quality.
Description
Technical field
This utility model relates to die casting technical field, particularly relates to a kind of device carrying out for die casting thick and large section and cooling down.
Background technology
The temperature of die casting thick and large section declines and always lags in the thin section of other wall, at casting solidification later stage thick and large section always
Lagging in the solidification of other section, as Engine Parts camshaft cover, bearing shell position is that whole casting section thickness is maximum
Position, when foundry goods is at in-mold molding, liquid when becoming solid-state, the section position that wall thickness is thick is always later than the low profile portion of wall
Position, the slag in such residual aluminum water, gas just concentrates on the position that wall thickness is thick, occur after causing the position processing that wall thickness is thick pore and
Cinder hole, therefore cooling down thick and large section in Die Casting is a basic method in Die Casting.
Most common method is to carry out water flowing cooling with cooling water pipe at present, as it is shown in figure 1, relative to foundry goods thick and large section
Die part, process a cooling duct, the end of cooling duct arrange a water inlet and an outlet, to this
In cooling duct, logical cooling water, cools down.But said structure is affected relatively big by mould structure, especially narrow in cooling duct
Narrow, and when passage is the deepest, cooling water pipe cannot access.
Utility model content
In order to solve above-mentioned technical problem, this utility model provides a kind of device carrying out for die casting thick and large section and cooling down.
This utility model simple in construction, is affected little by mould structure, and the suitability is strong, good cooling results, it is possible to effectively eliminate die casting table
The pore in face and shrinkage cavity, improve product quality.
Concrete technical scheme of the present utility model is: a kind of device carrying out for die casting thick and large section cooling down, including die casting
Mould, is provided with cooling duct corresponding at die casting thick and large section on described die-casting mould.It is provided with cold in described cooling duct
But rod, and be positioned on die-casting mould described cooling rod end be provided with intake tunnel and exhalant canal.
As preferably, described intake tunnel and exhalant canal lay respectively at the both sides of cooling rod end.
As preferably, the described external diameter of cooling rod was tight fit with the internal diameter of cooling duct.
As preferably, the head end of described cooling rod is provided with silica-gel coating.The setting of silica-gel coating is inserted after being easy to the installation that cooling is excellent.
As preferably, described cooling rod is red copper bar.Red copper has excellent thermal conductivity, and the heat of mould can be rapidly by red copper bar
Siphon away.
As preferably, on described die-casting mould, the end of cooling duct is provided with maintenance installing hole, sets in described maintenance installing hole
There is seal plug.It is used for installing, changing cooling rod, and the energy when breaking down in cooling duct when overhauling the effect of installing hole
Enough overhaul.
In the die part relative to die casting thick and large section, processing a cooling duct, this cooling duct is adopted with cooling rod outside diameter
With crossing friction tight tolerance, cool down bastinade during assembling and enter mould corresponding site, reach the last and coat silica gel on cooling rod top,
Boring enterprising, exhalant canal at mould corresponding site, when mould carries out heat exchange with die casting, cooling rod absorbs a part of mould
Heat, the end simultaneously cooling down rod is fully immersed in the cooling water of flowing, is all taken away by these heats, so to die casting
Thick and large section can carry out cooling.The circulation of each heat absorption and heat release goes round and begins again and is taken away by mould corresponding site heat, it is achieved
This device purpose to the cooling of die casting thick and large section.
Being compared with the prior art, the beneficial effects of the utility model are:
This utility model simple in construction, is affected little by mould structure, and the suitability is strong, good cooling results, it is possible to effectively eliminate die casting
The pore on part surface and shrinkage cavity, improve product quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of existing chiller；
Fig. 2 is a kind of structural representation of the present utility model.
Reference is: die-casting mould 1, cooling duct 2, cooling rod 3, intake tunnel 4, exhalant canal 5, and silica gel is coated with
Layer 6, seal plug 7.
Detailed description of the invention
Below in conjunction with embodiment, the utility model will be further described.Device, connection involved in this utility model are tied
Structure and method, if without refering in particular to, being device well known in the art, connection structure and method.
Embodiment 1
As shown in Figure 2: a kind of device carrying out for die casting thick and large section cooling down, including die-casting mould 1, in described pressure
It is provided with cooling duct 2 corresponding at die casting thick and large section on casting die.Being provided with material in described cooling duct is the cold of red copper
But rod 3, the head end of described cooling rod is provided with silica-gel coating 6, and the internal diameter of the external diameter of cooling rod and cooling duct was tight fit.
And the end being positioned at described cooling rod on die-casting mould is provided with intake tunnel 4 and exhalant canal 5.Described intake tunnel with go out
Aquaporin lays respectively at the both sides of cooling rod end.On described die-casting mould, the end of cooling duct is provided with maintenance installing hole,
It is provided with seal plug 7 in described maintenance installing hole.
The device busy principle of the present embodiment is: when molten metal is with the high temperature of 630 DEG C, be poured in mould, at high speed, height
During pressure molding, liquid metal and mould have violent heat exchange, substantial amounts of heat to be absorbed by mould, due to cooling rod and mould
Corresponding site is the cooperation of tight type, and red copper has excellent thermal conductivity, and the heat of mould can be siphoned away by red copper bar, cooling rod
End is immersed in and cools down in water, and the heat of cooling rod is taken away by cooling down water, makes the cooling rod temperature that holding is relatively low forever, each suction
The circulation of exothermic heat goes round and begins again and is taken away by mould corresponding site heat, it is achieved that this device is to the cooling of foundry goods thick and large section
Purpose.
The above, be only preferred embodiment of the present utility model, not impose any restrictions this utility model, every according to this
Any simple modification, change and the equivalent structure transformation that above example is made by utility model technical spirit, all still falls within this
The protection domain of utility model technical scheme.
