Abstract
The invention relates to the technical field of dies and discloses a temperature control method of a loose core of a die-casting die. The temperature of a die frame and the loose core rise at the same time through a die-casting die temperature machine; the setting temperature of the die frame is 160-180 DEG C; the temperature of the loose core rises at three stages particularly including the first stage that setting temperature is 100-120 DEG C and keeps for 1-2 hours, the second stage that setting temperature is 180-200 DEG C and keeps for 1-2 hours and the third stage that setting temperature is 160-180 DEG C and keeps in the normal production process. The die-casting die temperature machine controls temperature rising of the loose core of the die-casting die in a staged mode and can avoid the situation that as the size of the loose core is small and the temperature rising is too rapid, a larger temperature gradient exists between the loose core and other positions of the die-casting die such as the die frame and a die core, the deformation amount of the loose core is large and the loose core is jammed. The method is easy to operate, can improve the production efficiency and can be widely applied to temperature control of the loose core of the die-casting die.
Description
Technical field
The present invention relates to technical field of mold, specifically a kind of die casting temperature-controlled process of loosing core.
Background technology
Die casting belongs to precision die, and its material is all generally iron-carbon alloy, the coefficient of expansion 0.0012%/DEG C about, i.e. the material warms 100 DEG C of length 1m, will expand about 1.2mm.
In the production process of die casting, various ways all can be adopted to carry out heat temperature raising to mould, comprise gas heating, aluminium alloy heating, die heater heating etc.Conventional mode of heating is all heat mold integral (comprise mould bases, die and loose core), due to loose core small volume, heat up very fast, and the volume of other positions of the mould such as mould bases, die is comparatively large, intensification is slower, cause thermograde excessive, the scuffing that often occurs loosing core, the problem such as stuck.In addition, because mold temperature is uneven, the mold use life-span also can reduce.
Summary of the invention
The present invention is directed to above-mentioned Problems existing, provide the temperature-controlled process providing a kind of die casting to loose core.
The present invention for achieving the above object, takes following technical scheme to be achieved:
The temperature-controlled process that die casting is loosed core, is characterized in that, described mould bases to be heated up by die casting die heater with loosing core simultaneously;
Described mould bases design temperature 160 ~ 180 DEG C;
Described loosing core is heated up by three phases, specific as follows: the first stage: design temperature 100 ~ 120 DEG C, keeps 1 ~ 2 hour; Second stage: set 180 ~ 200 DEG C, keeps 1 ~ 2 hour; Phase III: set 160 ~ 180 DEG C, and keep in normal productive process.
The temperature-controlled process that a kind of die casting according to claim 1 is loosed core, is characterized in that, described die casting die heater adopts heat transfer oil.
Compared with prior art, beneficial effect of the present invention is as follows: the present invention to be loosed core intensification by die casting die heater control by stages die casting, avoid heating up because volume of loosing core is little comparatively fast, itself and other positions of the die casting such as mould bases, die are caused to cause larger thermograde, thus the deflection that makes to loose core is excessive, cause loose core stuck.The inventive method is simple to operate, can enhance productivity, and can be widely used in during temperature that die casting looses core controls.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described, but embodiments of the present invention are not limited thereto.
The temperature-controlled process that a kind of die casting is loosed core: mould bases to be heated up by die casting die heater with loosing core simultaneously; Mould bases design temperature 160 ~ 180 DEG C;
Loose core and to be heated up by three phases, specific as follows: the first stage: design temperature 100 ~ 120 DEG C, keep 1 ~ 2 hour; Second stage: set 180 ~ 200 DEG C, keeps 1 ~ 2 hour; Phase III: set 160 ~ 180 DEG C, and keep in normal productive process.
Wherein, die casting die heater adopts heat transfer oil.
In the embodiment of the present invention, direct setting die casting die heater temperature is 160 ~ 180 DEG C and heats up to mould bases, and heating rate is very fast; To loosing core, three phases is divided to heat up, as lower in first stage design temperature, be 100 ~ 120 DEG C, and keep 1 ~ 2 hour, can effectively slow down the heating rate of loosing core; The setting of second stage temperature is slightly higher, is 180 ~ 200 DEG C, is because die heats up by loosing core and mould bases conduction, slightly high at second stage design temperature, can make to loose core identical with mould bases heating rate, avoid the temperature difference, can also, by heat conduction to die, whole mould be made to keep identical temperature; Temperature is set as normal production temperature by three phases, is 160 ~ 180 DEG C, and now, whole mold temperature all reaches 160 ~ 180 DEG C.
The present invention to be loosed core intensification by die casting die heater control by stages die casting, avoid heating up because volume of loosing core is little comparatively fast, cause itself and other positions of the die casting such as mould bases, die to cause larger thermograde, thus the deflection that makes to loose core is excessive, cause loose core stuck.The inventive method is simple to operate, can enhance productivity, and can be widely used in during temperature that die casting looses core controls.
Only as described above, be only the preferred embodiment of the present invention, when can not limit the scope of the present invention with this, namely generally according to equivalence change simple done by the content described in the claims in the present invention and description and modification, be all still covered by the claims of the invention.In addition, summary part and title are only used to the use of auxiliary patent document search, are not used for the interest field of restriction the present invention.
