Abstract
The invention discloses a quick cooling die for aluminum pistons produced through gravity casting. The quick cooling die comprises an outer die upper block and an outer die lower block which are combined together vertically; the outer die upper block is provided with a cooling channel; the top of the outer die upper block is provided with a top die matched with the outer die upper block; the top die is also provided with a cooling channel; pin cores are horizontally arranged on the outer die lower block; a cooling channel is formed in each pin core; an inner core which is closely matched with two pin cores is arranged between the two pin cores left and right; a cooling channel is formed in the inner core; except the cooling channel of the top die, cooling tubes are arranged in all cooling channels. By adopting the structure, the quick cooling die for the aluminum pistons produced through gravity casting can realize modular production, the preparation time for the die can be shortened, and the capacity of piston manufacturers to respond production change is improved. Meanwhile, the die is easier to produce and maintain, and the production cost is reduced.
Description
Technical field
The present invention relates to the quick cooling die of a kind of gravitational casting aluminium recovery.
Background technology
At present, most of Casting Aluminum Piston enterprise all realizes 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 also there is great problem.Under loose core and cause most piston blank feeding head to be arranged in above the thick enlarged head of piston, thus cause the slower top land of original cooling velocity to be more difficult to cooling, make it to obtain fine and close tissue, mechanical performance is poor.And the key positions such as combustion chamber, interior oil cooling passage, abrasion-proof inserted ring are all positioned at piston crown.Therefore, the inefficacy of most of piston all occurs in this region.Meanwhile, because the cooling of this position is comparatively slow, the bottleneck improving casting production efficiency is become.
Summary of the invention
The object of the invention is to the deficiency existed for prior art, provide a kind of gravitational casting aluminium recovery quick cooling die, improve piston machine performance and casting production efficiency.
Object of the present invention is achieved through the following technical solutions.
The quick cooling die of a kind of gravitational casting aluminium recovery, to comprise on the external mold combined up and down block under block and external mold, block is provided with cooling duct with described external mold; On external mold, the backform be mated is arranged at block top, described backform is also provided with cooling duct, horizontal mount pin core on block under external mold, described pin in-core is provided with cooling duct, between the pin core of two, left and right, have close-fitting inner core with it, core inner is provided with cooling duct in described; Except backform cooling duct, in described cooling duct, be equipped with cooling tube.
Described inner core combines 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, block is provided with cooling duct, in described cooling duct, arranges cooling tube.
Described backform combines by upper and lower two pieces, is wherein furnished with cooling duct in block under backform, and on backform, blocks design has casting combustion chamber.
Under described external mold, block and inner core are provided with seam circle between block, achieve external mold, the accurate location of inner core and cooperation dexterously.
Beneficial effect of the present invention have following some:
Adopt the quick cooling die of gravitational casting aluminium recovery of said structure, by by die assembly design mix moulds such as external mold, inner core, backforms, and insulation voids is set between inner core two parts, to greatest extent the cooling fluid of these three die assemblies can be concentrated and act on the thick large part of aluminum piston blank, and reduce the cooling effect of cooling fluid to blank thin-walled portion.Be combined with the PLC control system of existing casting machine, easily can realize the accurate control of cooling water, realize the consecutive solidification of piston blank, ensure that each position of whole piston can obtain better both macro and micro tissue.By design casting combustion chamber in block on backform, effectively can reduce this position blank thickness, accelerate solidifying of this position blank further.Compared with prior art, effectively can improve microscopic structure grade, and then improve the mechanical performance of piston, extend the service life of piston.
Adopt the quick cooling die of gravitational casting aluminium recovery of said structure, effectively can shorten the setting time of aluminum piston blank, improve its casting production efficiency.
Adopt the quick cooling die of gravitational casting aluminium recovery of said structure, can modularized production be realized, shorten the time of mould, improve piston manufacturing enterprise for the adaptibility to response of producing change.Make simultaneously the production of mould, safeguard be more prone to, reduce production cost.
