Description
Technical field
The present invention relates to sand casting fields, and in particular to a kind of die cast method.
Background technique
The casting of ironcasting mostly uses greatly sand casting, and sand casting is a kind of tradition casting using silica sand as main material
Make technique, it is necessary first to make model, core box, bottom plate and sandbox, then carry out upper and lower sand on upper and lower sandbox with being blended sand
The moulding and coremaking of type；And sand core is assembled in sandbox, mould assembling casting.
It is had the following problems in existing sand casting process: 1) needing to consume high-quality timber production model, and make
Period is long, costly, should not store；2) a large amount of toolings, such as sandbox, bottom plate are needed；3) molding sand is needed to be blended and regeneration treatment
The investment of equipment, sand using amount is bigger, and expense is higher, and sand can generate loss in regenerative process, leads to the consumption and work of resource
Industry waste generates；4) since the size of sandbox is fixed, size cannot be changed with casting and flexibly, cause mold thickness big, casting at
This height；5) traditional sand mould casting method is difficult to control the mechanical performance and outer dimension of casting, complex-shaped it is particularly difficult to prepare
Casting.
Currently, also there is the process cast using metal mold, but cast using metal mold, it is general only suitable
For the casting of the lower material of fusion temperature, and usually metal mold is not used to be cast iron casting.Therefore,
A kind of die cast method of the casting suitable for cast iron quality becomes the target of those skilled in the art's pursuit.
Summary of the invention
The present invention be in order to overcome in the prior art ironcasting need to cause using a large amount of molding sand in sand casting process
The technical issues of production efficiency is low, generates pollution, and properties of product should not guarantee, provides a kind of die cast method, Neng Gou great
Width reduces the usage amount of molding sand, improves the performance and production efficiency of product, while can prepare complex-shaped casting, realizes number
Word containerless casting production.
The present invention provides a kind of die cast method, and the casting method carries out after using metal die and sand core group type
Casting, wherein metal die is had by metal with pattern and is in close contact and has certain thickness with type mould inner surface with metal
