Description
Technical field
The present invention relates to a kind of sand mould structures of three cylinder crankshafts of casting field more particularly to automobile engine.
Background technology
Three cylinder crankshaft of engine system is the product of a Novel platform, same to substitute same four cylinder crankshaft of discharge capacity
A engine flat can be applicable in more money vehicles, and the demand of this product is larger, since product works under high speed rotation, and
Three cylinders should meet the requirement of high speed rotational operation static strength, meet fatigue strength requirement again, and compare into 120 degree of relationships
Four cylinder crankshafts, to the surface quality requirements higher of connecting rod, so big yield and quality requirement cause manufacturing enterprise to be faced with sternly
High challenge.
The similar product of traditional handicraft casting at present, using four cavity schemes of symmetric design, ingate and cross gate are complete
Portion is placed on cope, causes product sand washing waste product higher, and in order to solve connecting rod inner surface shrinkage porosite, all using profile-followed cold
Iron process, the profile-followed Chill production efficiency is low, and post processing labor workload is big, and product quality performance is general, unfavorable
It is competed in the marketization in enterprise.
It is therefore desirable to design a kind of new running gate system technique that can slow down sand washing, and profile-followed Chill is not used,
Ingate is placed into drag box, and increase small hot riser technique (cancelling profile-followed chill) in respective link outer fix, from
And reaching reduces sand washing waste product, eliminates connecting rod inner surface shrinkage porosite, and can improve production efficiency, three cylinders for reducing production cost are bent
Axle mould has running gate system.
