Abstract
The invention discloses a kind of casting method of Aluminum Alloy Cover, it is related to Casting Technology field, comprises the following steps：A, making and the supporting swage external form of apperance, gap when swage external form is with apperance matched moulds are 6~9mm；B, apperance is fixed in penetrating sand machine, closes swage external form, swage external form is heated together with apperance；C, by penetrating sand machine by precoated sand full of cavity between apperance and swage external form, molding after 2 minutes obtains the swage external form with cast die cavity；D, one layer of alcohol zircon flour coating of cast die cavity surface spraying to swage external form；E, by being placed in after swage external form matched moulds between electromagnet the two poles of the earth, switch on power make electromagnet produce magnetic field, pour into a mould aluminium liquid, after aluminium liquid fill cast die cavity and solidify after cut off the electricity supply, obtain Aluminum Alloy Cover.Compared with prior art, the cast die cavity of swage external form of the present invention is unlikely to deform, any surface finish, pours the Aluminum Alloy Cover precision outpoured high, it is not necessary to reserved machining amount.
Description
Technical field
The present invention relates to Casting Technology field, especially a kind of casting method of Aluminum Alloy Cover.
Background technology
Aluminum Alloy Cover lighter weight, long-term use is hardly deformed, durable in use.Generally closed using the aluminium of Foundry Production
Golden end cap blank, which is processed, to be formed, and must not have the casting flaws such as shrinkage porosite, stomata, sand holes after processing.Existing aluminium alloy
The Aluminum Alloy Cover blank precision of the casting method production of end cap is low, there is a small amount of casting flaw, it is necessary to reserve necessarily
Machining amount.
The content of the invention
Problem to be solved by this invention is to provide a kind of casting method of Aluminum Alloy Cover, can solve existing method life
The Aluminum Alloy Cover blank precision of production is low, there is a small amount of casting flaw, it is necessary to the problem of reserving certain machining amount.
In order to solve the above problems, the technical solution adopted by the present invention is：The casting method of this Aluminum Alloy Cover, including
Following steps：
A, making and the supporting swage external form of apperance, gap when swage external form is with apperance matched moulds are 6~9mm；
B, apperance is fixed in penetrating sand machine, closes swage external form, swage external form is heated to 240~270 DEG C, guarantor together with apperance
Temperature 15~20 minutes；
C, precoated sand is mapped to by swage external form inner chamber by penetrating sand machine, makes precoated sand full of the sky between apperance and swage external form
Chamber, molding after 2 minutes obtains the swage external form with cast die cavity after cooling；
D, one layer of alcohol zircon flour coating of cast die cavity surface spraying to swage external form；
E, by being placed in after swage external form matched moulds between electromagnet the two poles of the earth, switch on power make electromagnet produce magnetic field, pour into a mould aluminium liquid, treat
Aluminium liquid fills cast die cavity and cut off the electricity supply after solidifying, and Aluminum Alloy Cover is obtained after cooling.
In the casting method technical scheme of above-mentioned Aluminum Alloy Cover, more specifically technical scheme can also be：The overlay film
Sand is made up of the raw material of following parts by weight：It is 90~100 parts of zircon sand, 1~1.5 part of phenolic resin, 0.7~1 part of methenamine, hard
0.4~0.6 part of resin acid calcium, 0.3~0.5 part of microcrystalline wax, 0.2~0.3 part of vegetable esters of synthesis；The precoated sand prepared passes through
140~180 eye mesh screens.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
1st, the cast mold cavity surface of swage external form of the invention is covered with one layer of precoated sand, and sprays one layer of alcohol zircon flour painting
Material, is unlikely to deform cast die cavity, any surface finish, pours the Aluminum Alloy Cover precision height outpoured, and surface is also bright and clean, and in electromagnetic field
Crystallization is poured into a mould in the presence of power, casting flaw is eliminated, it is not necessary to reserved machining amount.
2nd, the precoated sand that the raw material of precoated sand is constituted and prepared enables aluminum alloy to the table of end cap by 140~180 eye mesh screens
Surface roughness reaches Ra3.2um, it is not necessary to which machining is with regard to that can reach technical requirements.
