Description
Technical field
The present invention relates to a kind of gravitational casting aluminium recovery and quickly cool down mould.
Background technology
At present, most of Casting Aluminum Piston enterprises all realize casting mechanizing production.In mechanization production, following gravitational casting technology mature and reliable the most of loosing core, is also most widely used in actual production again.But wherein there is also problem greatly.Under loose core and cause most piston blank feeding head to be arranged in above piston thickness enlarged head, thus the top land causing original cooling velocity slower is more difficult to cool down, and is allowed to obtain the tissue of densification, and mechanical performance is poor.And the key positions such as combustion chamber, interior oil cooling passage, abrasion-proof inserted ring are respectively positioned on piston crown.Therefore, the inefficacy of most of pistons all occurs in this region.Meanwhile, because the cooling of this position is relatively slow, the bottleneck improving casting production efficiency is become.
Summary of the invention
Present invention aims to the deficiency that prior art exists, it is provided that a kind of gravitational casting aluminium recovery quickly cools down mould, improves piston machine performance and casting production efficiency.
The purpose of the present invention is achieved through the following technical solutions.
A kind of gravitational casting aluminium recovery quickly cools down mould, including block under block on the external mold combined up and down and external mold, is provided with cooling duct on described external mold on block；On external mold, the backform coordinated with it is arranged at block top, also being provided with cooling duct on described backform, be transversely mounted pin core under external mold on block, described pin in-core is provided with cooling duct, between the pin core of two, left and right, there is the most close-fitting inner core, be provided with cooling duct at described interior core inner；In addition to backform cooling duct, in described cooling duct, it is equipped with cooling tube.
Described inner core is combined by upper and lower two pieces, and described inner core is provided with insulation voids between block under block and inner core.
Under described inner core, it is provided with cooling duct on block, described cooling duct is arranged cooling tube.
Described backform is combined by upper and lower two pieces, is wherein disposed with cooling duct under backform in block, and on backform, block is designed with casting combustion chamber.
Under described external mold, it is provided with seam circle between block on block and inner core, achieves external mold, being accurately positioned and coordinate of inner core dexterously.
Beneficial effects of the present invention have following some:
The gravitational casting aluminium recovery using said structure quickly cools down mould, by the die assemblies such as external mold, inner core, backform are designed to Split mold, and insulation voids is set between inner core two parts, to greatest extent the coolant of these three die assemblies can be concentrated and act on aluminum piston blank thickness large part, and reduce the coolant cooling effect to blank thin-walled portion.Be combined with the PLC control system of existing casting machine, can easily realize cooling down the accurate control of water, it is achieved the consecutive solidification of piston blank, it is ensured that each position of whole piston can obtain more preferable both macro and micro tissue.By design casting combustion chamber in block on backform, can effectively reduce this position blank thickness, further speed up the solidification of this position blank.Compared with prior art, one grade of microscopic structure, and then the mechanical performance of raising piston can be effectively improved, extend the service life of piston.
The gravitational casting aluminium recovery using said structure quickly cools down mould, can effectively shorten the setting time of aluminum piston blank, improve its casting production efficiency.
The gravitational casting aluminium recovery using said structure quickly cools down mould, can realize modularized production, shortens the time of mould, improves piston manufacturing enterprise for producing the adaptibility to response of change.Make the production of mould, maintenance be more prone to simultaneously, reduce production cost.

Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, gravitational casting aluminium recovery quickly cools down mould, and it is mainly made up of assemblies such as external mold, inner core, backform, seam circle 14 and pin cores 8；External mold is combined with block on external mold 2 by block under external mold 1, and external mold is disposed with in block 2 external mold cooling duct 3；On external mold, the backform coordinated with it is arranged at block 2 top, backform also is provided with backform cooling duct 5, pin core 8 it is transversely mounted on block under external mold, pin core cooling duct 9 it is provided with in described pin core 8, between the pin core 8 of two, left and right, there is the most close-fitting inner core, be provided with cooling duct at interior core inner；In addition to backform cooling duct 5, in all cooling ducts, it is equipped with cooling tube.
Inner core is combined by block 12 under block on inner core 10 and inner core.It is disposed with insulation voids 11 between block 12 under block 10 and inner core on inner core, block 11 is disposed with under inner core inner core cooling duct 15, inner core cooling duct 15 has inner core cooling tube 13, make the coolant of cooling duct more concentrate and act on block 12 top under inner core.Insulation voids has also reserved space for expanding with heat and contract with cold of block 12 under inner core.It is provided with seam circle 14 between block 10 on block 1 and inner core under external mold.
Backform is combined by block 6 on block under backform 4 and backform.Block 4 is disposed with backform cooling duct 5, design part casting combustion chamber 7 in block 6 on backform under backform.
