Abstract
The utility model discloses a sprue bush with the long service life. The sprue bush comprises a sprue bush body (1) and a sprue water jacket (2), wherein the sprue water jacket is in a hollow cylindrical structure and is arranged outside the sprue bush body in a sleeving manner; a round hole I (4) and a round hole II (5) are formed in two ends of the outer wall of the sprue water jacket, respectively; a ring-shaped cooling water tank (3) is formed in the inner wall of the sprue water jacket; the round hole I and the round hole II are communicated with the cooling water tank, respectively. The sprue bush has the beneficial effects that the cooling water tank is formed in the inner wall of the sprue water jacket, namely, the thickness of the wall of the sprue bush is kept same; in the injection process, even an injection punch and a sprue bush are in direct contact, due to the fact that the thickness of the wall of the sprue bush is kept same, frictional force of the sprue bush and the injection punch is reduced with the cooling of water, the sprue bush is hard to break or crack, and therefore, the service life of the sprue bush is prolonged, the production cost is reduced, and the unnecessary workload caused by changing the sprue bush is reduced, and the production efficiency is improved accordingly.
Description
Technical field
The utility model relates to a kind of sprue external member, specifically a kind of sprue external member of long service life.
Background technology
Sprue bush is for connecting into the important structure part of mould and die casting machine, in Die Casting process, what can affect moulding quality is temperature field, speed, the approach of whole injection moulding melt flows, sprue temperature is the highest, cool time is the longest, and the sprue of high temperature can cause products formed distortion serious, therefore need cooling device be set to sprue bush.Existing sprue external member structure is mostly: the outer wall of sprue bush offers annular bosh, cast gate water jacket is sheathed on sprue bush outside, cast gate water jacket two ends are respectively arranged with ostium and the tap hole communicating with bosh, cooling water enters bosh from ostium, through tap hole, discharge again, the temperature adjustment of sprue bush may have been become.But sprue bush bosh place wall thickness attenuation, in injection process, because injection punch head directly contacts with sprue bush, frictional force is larger, therefore sprue bush is stressed large, thereby cause sprue bush bosh place to occur that slight crack even ruptures, because slight crack easily blocks injection punch head, the disconnection of sprue bush simultaneously causes normally producing, need often to change sprue bush, service life is short, causes production cost to increase, and production efficiency reduces.
Summary of the invention
The utility model provides a kind of sprue external member of long service life, can reduce the Break frequency of sprue bush in production, extends the service life of sprue bush, thereby reduces production costs, and enhances productivity.
The technical solution adopted in the utility model is: a kind of sprue external member of long service life, comprise sprue bush and cast gate water jacket, cast gate water jacket is the cylindrical structural of hollow, be sheathed on sprue bush outside, cast gate water-jacket outer wall two ends are respectively arranged with circular port I and circular port II, cast gate water jacket inwall offers the bosh of ring-type, and circular port I and circular port II communicate with bosh respectively.
The beneficial effects of the utility model are: compared with prior art, this sprue external member is opened in cast gate water jacket inwall place by bosh, the wall thickness that is equivalent to sprue bush remains unchanged, in injection process, even if injection punch head directly contacts with sprue bush, because the wall thickness of sprue bush remains unchanged, reduced the frictional force of sprue bush and injection punch head, sprue bush is not prone to slight crack or phenomenon of rupture, extended the service life of sprue bush, thereby reduced production cost, reduced the unnecessary workload increasing because changing sprue bush, improved production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, sprue bush, 2, cast gate water jacket, 3, bosh, 4, circular port I, 5, circular port II.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of sprue external member of long service life, comprise sprue bush 1 and cast gate water jacket 2, the cylindrical structural that cast gate water jacket 2 is hollow, be sheathed on sprue bush 1 outside, cast gate water jacket 2 outer wall two ends are respectively arranged with circular port I 4 and circular port II 5, and cast gate water jacket 2 inwalls offer the bosh 3 of ring-type, and circular port I 4 and circular port II 5 communicate with bosh 3 respectively.
Further, bosh 3 is ring-type waveform tank, has increased the temperature of sprue bush 1 is adjusted to area, offer altogether three boshes 3 simultaneously, be distributed in the upper, middle and lower portion of cast gate water jacket 2, sprue bush 1 is realized evenly cooling, thereby produce the products formed of stabilizing quality.
Further, sprue bush 1 and cast gate water jacket 2 interference fit, realized good cooling effect.
Preferably, the WeiUXing cross section, longitudinal section of bosh 3, has avoided the bosh 3 of triangle or rectangle easily in angle, to form the phenomenon of stagnant water, compares with semicircular bosh 3 simultaneously, has increased the volume of bosh 3.
During work, cooling water flows into bosh 3 from the circular port I 4 of cast gate water jacket 2, finally by circular port II 5, discharges, and realization is cooling to sprue bush 1 sprue.Bosh 3 is opened in the inner wall position of cast gate water jacket 2, the wall thickness that is equivalent to sprue bush 1 remains unchanged, in injection process, even if injection punch head directly contacts with sprue bush 1, because the wall thickness of sprue bush 1 remains unchanged, reduced the frictional force of sprue bush 1 with injection punch head, sprue bush 1 is not prone to slight crack or phenomenon of rupture, has extended the service life of sprue bush 1, has reduced production cost, reduce the unnecessary workload increasing because changing sprue bush 1, improved production efficiency.
