Specific embodiment
As shown in Figure 1-3, Fig. 1 is a kind of axial section view of the charging barrel of die casting machine with heating device proposed by the present invention
Figure, Fig. 2 are a kind of radial cross-section of the charging barrel of die casting machine with heating device proposed by the present invention, and Fig. 3 is that the present invention proposes
A kind of charging barrel of die casting machine with heating device axial partial sectional view.
Referring to Fig.1-2, a kind of charging barrel of die casting machine with heating device proposed by the present invention, including it is barrel ontology 1, multiple
Medium pipeline, sleeve 3 and temperature sensor 4；
Barrel ontology 1 is equipped with feed inlet by the position of close end, and feed inlet enters in barrel for metallic solution, barrel ontology
1 peripheral wall is equipped with a ring annular groove, and annular groove extends to the end far from feed inlet from the position close to feed inlet；
Multiple medium pipelines are disposed axially in annular surface along barrel ontology 1, and medium pipeline passes through for heat medium
Realize the heating to barrel, medium pipeline includes medium inflow segment 21, ring segment 22 and medium the outflow section 23 of sequential communication, is added
Thermal medium sequence flows through medium flow field and enters section 21, ring segment 22 and medium outflow section 23, and ring segment 22 is centered around annular surface,
Conducting the heat of medium to barrel；
Sleeve 3 is mounted in annular groove to cover multiple ring segments 22, and sleeve 3 is used to protect ring segment 22,
Sleeve 3 and annular surface are filled with thermal insulation material 5, and thermal insulation material 5 can distribute to avoid the heat of medium into air；
Temperature sensor 4 is mounted on barrel ontology 1 for detecting 1 temperature of barrel ontology.
In the present embodiment, the charging barrel of die casting machine with heating device proposed, temperature reality of the temperature sensor 4 to barrel
When monitor, when monitoring barrel temperature lower than metallic solution temperature, medium is out of medium pipeline by add to barrel
Heat avoids molten metal temperature from being lowered, it is ensured that die-casting process formation condition is met, and molten metal is avoided to be adhered to barrel
On inner wall.
Since temperature gradually decreases medium during by ring segment 22, such barrel is close to medium inflow segment 21
Temperature is higher, and the temperature close to medium outflow section 23 is lower, in order to solve this problem, in the present embodiment, medium inflow segment 21
It is located at the same diametrical direction of ring segment 22 with the junction of the junction of ring segment 22 and medium outflow section 23 and ring segment 22
On, multiple medium pipelines are arranged in parallel, and medium flow direction is on the contrary, referring to Fig.1 in arbitrary neighborhood medium pipeline, the upper and lower position of barrel
Homogeneous heating is not in barrel a certain position temperature lower the case where causing molten metal to be adhered at this.
In order to improve antipyretic rate, referring to Fig. 3, each medium pipeline includes multiple ring segments 22, and multiple ring segments 22 are simultaneously
Connection connection, medium inflow segment 21 and medium outflow section 23 with simultaneously it is multiple annular pipeline sections be connected to, medium from medium inflow segment 21 into
Enter multiple ring segments 22, then enter medium from multiple ring segments 22 and flow out section 23, so that improving medium conducts heat to barrel
On rate.
Molten metal also can gradually lower from feed inlet to temperature during the endwall flow far from feed inlet, thus medium exists
Far from feed inlet position to the heating amount of barrel can be less than medium close to feed inlet position at medium to barrel
Heating amount, in the present embodiment, the distance between adjacent media pipeline is laterally away from the feed inlet from close to the feed inlet one
Side is gradually increased, medium in barrel heating process, present temperature from close to gating location to far from gating location by
Decrescence low trend is adapted with the temperature trend of barrel inner metal liquid；In another design method, medium pipeline diameter
