Abstract
The utility model discloses a die-casting formation feeding runner for a timing chain guard. The die-casting formation feeding runner comprises a sprue and a phi63 hole, wherein a gap bridge is arranged at the phi63 hole along the diameter direction; and one end of the gap bridge is arranged at the sprue. In the utility model, the structure of the die-casting formation feeding runner for the timing chain guard is improved, a novel pouring structure is adopted, and the loosening defects at the deep part of a timing chain guard cavity are effectively eliminated.
Description
Technical field
The utility model relates to a kind of die casting, especially a kind of improved chain guard casting forming feeding in correct time running channel.
Background technology
Correct time, chain guard was the parts that cooperate with cylinder block, crankcase, cylinder cover on the automobile engine, and average wall thickness has only 2.5mm, and in order to prevent the generation of leakage of oil, the foundry goods all sites does not all allow the appearance of casting flaws such as shrinkage porosite.
Correct time, chain guard belonged to thin-walled, plate casting, and from a side charging, aluminium liquid is horizontal sliding forward uniformly during die casting, thereby and then filled up the whole die cavity of mould and accomplish casting forming.Fig. 1 is original the water row structure of correct time during the chain guard casting forming, and 1 is cast gate, the 2nd among the figure, φ 63 holes, its defective is: the aluminium liquid that gets into from the cast gate position since the core in moulding φ 63 holes exist, thereby hindered flowing of aluminium liquid, influence the feeding effect.Find in the production; Though adopt the original row of watering structure can make the most shaping of foundry goods intact, there is serious loose phenomenon in position shown in the A among Fig. 3, the dark 27.5mm in this chamber, position; Aluminium liquid spreads to the depths from it rapidly all around during charging, causes a part of gas to discharge; In addition, because dark position, chamber mold temperature is lower, aluminium liquid takes the lead in solidifying, and makes this place obtain good feeding in pressurization stages, so very easily produce loose.And the adjusting process parameter can not well address this problem, and therefore must address this problem from the improvement of mould structure.
Summary of the invention
In order to overcome the problem that prior art exists; The purpose of the utility model provides a kind of chain guard casting forming feeding in correct time running channel; The utility model has improved chain guard casting forming feeding in correct time running channel structure; Adopt the novel row's of watering structure, effectively eliminated the rarefaction defect of position, deep, chain guard chamber in correct time.
The purpose of the utility model realizes through following technical scheme:
A kind of chain guard casting forming feeding in correct time running channel comprises cast gate and φ 63 holes, it is characterized in that: the place is provided with gap bridge along diametric(al) in φ 63 holes, and an end of this gap bridge is arranged on the cast gate place.
In the utility model, the width of said gap bridge and φ 63 holes are suitable, and width is 10-20mm.
The beneficial effect of the utility model is: adopt chain guard casting forming feeding in the correct time running channel after improving, dark position, chamber has obtained good feeding, has avoided the generation of loose phenomenon, and the institutional framework at this position meets the requirements behind the casting forming.
Description of drawings
Fig. 1 is the original row of watering of chain guard in correct time structural representation in the prior art.
Fig. 2 is the structural representation of the utility model.
Fig. 3 is position, the dark chamber of chain guard in a correct time sketch map.
The specific embodiment
A kind of the utility model chain guard casting forming in described correct time feeding running channel is seen Fig. 2, and this running channel comprises cast gate 1 and φ 63 holes 2, is provided with gap bridge 3 at 2 places, φ 63 holes along diametric(al), and an end of this gap bridge 3 is arranged on cast gate 1 place.The width and φ 63 holes of gap bridge 3 are suitable, and width is 10-20mm.
The utility model increases a bridge structure at the core end face in moulding φ 63 holes, after aluminium liquid gets into from cast gate, walks around the obstruction of φ 63 pass cores, via passing a bridge feeding is carried out at position, dark chamber.In subsequent handling, gap bridge is knocked out, the geomery of foundry goods is not had any influence.Adopt chain guard casting forming feeding in the correct time running channel after improving, dark position, chamber has obtained good feeding, has avoided the generation of loose phenomenon, and the institutional framework at this position meets the requirements behind the casting forming.
