Abstract
The invention involves a casting mold of diesel alloy diesel engine base and its casting method. The casting mold uses one side sand mold and three side melt mold to forming the out mold, it is help ensure the appearance quality of base; uses S-shaped straight pouring channel and netted inner pourer gravity casting, it is help uniform and smooth of aluminum liquid filling during casting; while puts melt cooling pieces on the partial location of sand mold and main core to changing aluminum liquid cool solidification order in the filling mold process, it can reduce the possibility of casting defects. Practice has proved that the casting method can improve the rate of finished products of base products greatly during the production process of diesel alloy diesel engine base and achieve good economic results.
Description
Technical field
The present invention relates to a kind of casting mould and casting method, particularly relate to a kind of casting mould and casting method of aluminum alloy diesel engine base.
Background technology
Casting is the mode of production of multiple device, makes the field at engine, and casting is one of important means, for example parts such as engine framework, engine body, engine cover.Wherein the casting of aluminum alloy diesel engine base has higher difficulty, at present, domestic seldom have can successful Birmasil diesel engine base foundry goods enterprise.The characteristic that the complexity of aluminum alloy diesel engine base foundry goods and aluminium alloy are intrinsic makes that the successful production difficulty of aluminum alloy diesel engine base foundry goods is a lot.Produce similar foundry goods both at home and abroad, for example aluminium alloy gasoline engine foundry goods has the employing high-pressure casting; The full sand mold gravitational casting of employing is arranged, and be aided with the production of water pipe cooling means, the percent defective of the foundry goods of producing is very high, and production efficiency is low excessively, does not far reach the requirement of enterprise.And if, sizable danger were arranged in the cooling of casting process employing water pipe, there is certain potential safety hazard.
Summary of the invention
At the deficiencies in the prior art, the invention provides a kind of aluminum alloy diesel engine base casting mould and casting method, can change in the casting process local cooled and solidified order, enhance productivity and the qualification rate of product.
Aluminum alloy diesel engine base casting mould structure of the present invention comprises three side metal patterns, a side sand mold mould, main body sand core and rising pouring core, and cast gate is arranged at sand mold mould one side.The metal cooling block of suitable number is set in the local suitable location of sand mold mould and main body sand core.The rising pouring sand core structure comprises S shape sprue and netted multipoint mode ingate.
Three side metal patterns and a side sand mold mould constitute external mold, and outer mold cavity is provided with main body sand core, and the main body sand core bottom is the rising pouring core, and the netted multipoint mode ingate of rising pouring core is corresponding with the space of main body sand core.
Aluminum alloy diesel engine base casting method process of the present invention comprises: require to manufacture three side metal patterns, a side sand mold mould, main body sand core and rising pouring core according to stand structure; At a side sand mold mould and the local suitable location of main body sand core the metal cooling block is set; In order with three side metal patterns, rising pouring core, main body sand core, side sand mold module dress; Molten aluminium alloy is injected mould, cooling, die sinking obtains the support foundry goods; Three side metal patterns and metal cooling block are reused.
The present invention adopts three side metal patterns and side sand mold mould (watering an oral-lateral) structure, bottom filling gravitational casting.At sand mold mould and the local metal cooling block that increases of main body sand core, change local cooled and solidified order, to guarantee the needing feeding position to obtain fully effectively feeding.Adopt S shape sprue and netted ingate gravitational casting, help the even, steady of in pour into a mould kind aluminum liquid filling type.Adopt above-mentioned technical characterictic, can improve the productivity ratio that aluminum alloy diesel engine base is produced greatly, and the rate of reducing the number of rejects and seconds greatly, facts have proved that the design obtains very desirable effect in foundry production.
Technique effect highly significant of the present invention: adopt three side metal patterns, with respect to the sand mold mould, good cooling results not only, the surface of foundry goods is very attractive in appearance, and surface quality is very desirable; By changing local cooled and solidified order, make the casting wasted product rate of producing be controlled in the very desirable scope, the production efficiency height has been obtained extraordinary economic benefit.
