Description
Technical field
The present invention relates to sand mold mould manufacturing technology fields, and in particular to a kind of manufacturing method of column sand mo(u)ld.
Background technology
Sand casting refers to the casting method that casting is produced in sand mold.Steel, iron and most of non-ferrous alloy castings all may be used
To be obtained with sand mould casting method.Sand casting is one kind in casting technique, and casting mold used in sand casting is generally by outer sand mold
It is composed with core.Since the Modeling Material used in sand casting is cheap and easy to get, Casting mold manufacturing is easy, and the single-piece of casting is given birth to
It produces, produce by batch and adapted to mass production, be always the basic technology in Foundry Production for a long time.
Mold is made of using wood or other metal materials in sand casting.In this process, mold ruler is made
Very little to be slightly larger than finished product, difference therein is known as allowance for shrinkage.Wherein purpose is that fusing metal is golden to ensure to melt to mould action
Belong to solidification and shrink, so as to prevent the cavity in casting process.
The basic raw material for manufacturing sand mold is casting model powder and moulding sand binder.Most common casting model powder is siliceous sand.Silica sand
High-temperature behavior when cannot meet requirement then using special sands such as zircon sand, chromite sand, emergies.To make manufactured sand
Type and core have certain intensity, will not deform or damage in carrying, mould assembly and pouring liquid metal, generally to cast
Loose sand grains is bonded as molding sand by middle addition moulding sand binder.
Column is one of important part on lathe, for not scale complex parts, generally by sand mold mould casting,
It needs the sand-cast after shaping being removed from the molds during sand mold mould is manufactured, during the demoulding, however, when casting
When surface texture is complex, sand-cast is susceptible to cracking or is bonded in dies cavity in knockout course, and demoulding difficulty is big,
Requirement is not achieved in obtained sand mold.
