The utility model discloses can ensure that the cylinder liner core is firmly fixed, the risk avoiding cylinder liner core drunkenness and pulled out. And greatly promoted the water -cooling ability, cylinder liner core temperature field is more balanced.
Description
Technical field
The utility model relates to die casting field, is specially a kind of for the moving die insert structure without the die casting of cylinder sleeve cylinder body.
Background technology
Cylinder body is the vitals of engine, and its quality requirement is higher, and generally can be divided into has cylinder sleeve cylinder body and without cylinder sleeve cylinder body two kinds.Aluminium alloy cylinder generally adopts casting forming, and without in cylinder sleeve cylinder body die casting, moving die insert is mainly used in the complex regions such as cylinder holes, water channel, spill port and is shaped, and is generally made up of parts such as jacket core 2, cylinder sleeve core 3 and cooling packages thereof.Existing structure is see Fig. 1: jacket core 2 is arranged on dynamic model cage plate 1, and cylinder sleeve core 3 loads in jacket core, is fixed on dynamic model cage plate 1 by bottom cylinder sleeve core set bolt 6.
Wherein, cylinder sleeve core water-cooling process technology is one of the major influence factors without cylinder sleeve aluminium alloy cylinder holes forming quality, mainly contain following two kinds of implementations at present: mode one is see Fig. 2: the cold pipe 5 in set-point in the blind hole in cylinder sleeve core 3, between the intake tunnel 501 put in cold pipe and exhalant canal 502, water flowing cools cylinder sleeve core; Mode two is see Fig. 3, and cylinder sleeve core 3 and water-cooled mold insert 7 are threaded connection, and water-cooled mold insert is provided with single screw water channel 7 01, and cooling water by inlet channel 702, single screw passage 701, water outlet 703, cools cylinder sleeve core with this successively.
Without in cylinder sleeve aluminium alloy cylinder Die Casting, because cylinder sleeve core is directly wrapped up by aluminium liquid, the cooling capacity of above-mentioned single blind hole or two kinds of water flowing types of cooling singly entering single exit spiral type is limited, water inlet and the water outlet temperature difference large, the defects such as cylinder sleeve core temperature field is uneven, and shrinkage cavity, sticking to mould easily appear in cylinder holes position, pull.In addition, foundry goods produces package power to cylinder sleeve core, there is cylinder sleeve core axial float, connecting bolt drawn risk that is loosening, mating surface crimp, affect product size precision, significantly reduce die life when foundry goods is ejected.
Summary of the invention
The purpose of this utility model is to provide a kind of for the moving die insert structure without the die casting of cylinder sleeve cylinder body, can fixedly secure cylinder sleeve core, and promote cooling capacity.
Described in the utility model for the moving die insert structure without the die casting of cylinder sleeve cylinder body, comprise dynamic model cage plate, jacket core and cylinder sleeve core, described jacket core is fixed on dynamic model cage plate, described cylinder sleeve core is located in jacket core endoporus, the periphery of described cylinder sleeve core bottom has boss, the endoporus of described jacket core coordinates with the boss of cylinder sleeve core, is pressed on described dynamic model cage plate by described cylinder sleeve core.
Preferably, columniform cooling water bolt is provided with in the endoporus of described cylinder sleeve core, the periphery of this cooling water bolt is provided with multi-head spiral groove, described multi-head spiral groove and cylinder sleeve core inner hole form multi-head spiral water channel, in the centre bore of described cooling water bolt, somewhat cold pipe is set, be provided with intake tunnel and exhalant canal in the cold pipe of described point, the water inlet at described multi-head spiral water channel top communicates with the intake tunnel of the cold pipe of point, and the delivery port bottom multi-head spiral water channel communicates with the exhalant canal of the cold pipe of point.
Preferably, described cooling water bolt is fixed in cylinder sleeve in-core hole by screw thread.
Preferably, described jacket core is fastened on dynamic model cage plate by set bolt.
Moving die insert structure described in the utility model, cylinder sleeve core and jacket core inner hole, the periphery boss of cylinder sleeve core is pressed on dynamic model cage plate by jacket core, make the radial and axial accurate positioning of cylinder sleeve core, fixation, ensures that cylinder sleeve core, without play, guarantees that product size precision reaches requirement under the effect of package power and ejecting force, extend die life, reduce cylinder sleeve core use cost.
In addition, built-in cooling water bolt can reduce cylinder sleeve core wall thickness, increase heat exchange area, remarkable lifting water-cooled effect, and multi-head spiral structure is compared with existing single-screw water channel, each cooling water channel flow process can be made to shorten, and cylinder sleeve core each several part Temperature Distribution is more even, defect, remarkable Improving The Quality of Products and the production efficiency such as effectively eliminate the shrinkage cavity of cylinder holes position, sticking to mould, pull.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, and following examples, only for explaining the utility model, do not form the restriction to the utility model protection domain.
As shown in Figure 4, Figure 5 for the moving die insert structure without the die casting of cylinder sleeve cylinder body, comprise dynamic model cage plate 1, jacket core 2, cylinder sleeve core 3, cooling water bolt 4 and put cold pipe 5.
Described jacket core 2 is fastened on dynamic model cage plate 1 by set bolt 6.Described cylinder sleeve core 3 is located in jacket core 2 endoporus, and the periphery of cylinder sleeve core 3 bottom has boss 301, and the endoporus of described jacket core coordinates with the boss of cylinder sleeve core, is pressed on described dynamic model cage plate by described cylinder sleeve core.
In the endoporus of described cylinder sleeve core, be provided with columniform cooling water bolt 4, the periphery of this cooling water bolt 4 is provided with multi-head spiral groove, and described multi-head spiral groove and cylinder sleeve core inner hole form multi-head spiral water channel 401.Described cooling water bolt 4 is fixed in cylinder sleeve core 3 endoporus by screw thread.
