This die cavity adopts the vacuum -exhaust mode, is showing the reduction gas pocket, and the messenger organizes finer and closely, improves the mechanical properties of foundry goods. The utility model provides a shrinkage cavity defect of the control arm made of current mould many, the rate of air hole is high, inside and surperficial hardness is not high, mechanical properties less than and problem that can not the industrialization.
Description
Technical field
The utility model relates to squeeze casting technology field, refers to a kind of die cavity of control arm squeeze casting mould especially.
Background technology
For the manufacture of automobile control arm, can the method such as selection pressure casting, forging produce.But the control arm internal porosity produced with pressure casting processes is more, cannot heat-treat, poor mechanical property; Although forging can meet internal soundness and performance requirement, following process amount is large, and cost is high; Extrusion casint is a kind of high-quality, efficient, energy-conservation novel green manufacturing technology between die casting and forging, is suitable for production high-performance, wear-resisting, sealing, high pressure and complex-shaped aluminium alloy stressed member.
But squeeze casting mould in the past only has Direct Squeezing Casting mould and indirect extrusion casting mould two kinds of forms, only implements disposable extruding when foundry goods is shaping, just cannot effectively transmit for the liquid phase isolated island pressure formed in process of setting.And very large and use crackle to be inclined to large alloy-steel casting for complex-shaped, wall thickness variation, disposable extruding just cannot meet the demands.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of die cavity of control arm squeeze casting mould, and it is more high-leveled and difficult with heat treatment, poor mechanical property and can not the problem of industrialization that the apical position of control arm produced to solve existing mold exists shrinkage cavity defect, the porosity.
This die cavity comprises sprue bush, one-sided feed type running channel, foundry goods die cavity, cinder ladle, exhaust block, secondary extrusion bar and fixed block, it is outside that sprue bush is positioned at one-sided feed type running channel, one-sided feed type running channel connects foundry goods die cavity, cinder ladle is distributed in around foundry goods die cavity, cinder ladle is communicated with foundry goods die cavity, exhaust block is connected with cinder ladle, and secondary extrusion bar is arranged on control arm top end by fixed block.
Wherein, cinder ladle totally ten two, be respectively cinder ladle one, cinder ladle two, cinder ladle three, cinder ladle four, cinder ladle five, cinder ladle six, cinder ladle seven, cinder ladle eight, cinder ladle nine, cinder ladle ten, cinder ladle 11 and cinder ladle 12, described exhaust block totally five, be respectively exhaust block one, exhaust block two, exhaust block three, exhaust block four, exhaust block five, wherein, cinder ladle two and cinder ladle three are pooled on exhaust block one, cinder ladle four and cinder ladle five are pooled on exhaust block two, cinder ladle six and cinder ladle seven are pooled on exhaust block three, cinder ladle eight and cinder ladle nine are pooled on exhaust block four, cinder ladle ten and cinder ladle 11 are pooled on exhaust block five.
Cinder ladle is connected with exhaust block by overflow air discharge duct, and exhaust block adopts vacuum exhaust mode.
This die cavity utilizes pressure ram to carry out secondary extrusion to control arm top end (be full of die cavity but do not solidify completely), eliminates the shrinkage cavity defect at this position; Adopt one-sided feeding manner, be conducive to the exhaust of foundry goods in casting process, avoid due to volume gas and occur large pore; In exhaust, adopt vacuum exhaust mode, can reduce pore significantly, make to organize finer and close, can also reduce and fill type counter-pressure, forming property is good, and surface quality is improved.
The beneficial effect of technique scheme of the present utility model is as follows:
The utility model carries out local compression by pressure ram to control arm apical position, eliminates the shrinkage cavity defect at this position; Vacuum exhaust mode significantly reduces the porosity, makes the foundry goods of production can heat treatment, improves inside quality and the mechanical property of foundry goods.
