The utility model is provided with the molten aluminum flow passage at the position of the bottom surface of the upper mold core, which is close to the end surface of the spoke cavity of the hub, and the molten aluminum flow passage has the design function of widening the passage between the riser and the casting cavity, so that molten aluminum on the riser flows onto the casting cavity more easily, the feeding quality is improved, the quality of the internal structure of the rim is improved, and the problem of loose defects during hub casting can be solved without additionally increasing the structure and affecting the original casting quality and cost.
Description
Technical Field
The utility model belongs to the technical field of manufacturing of motorcycle rims, and particularly relates to a gravity casting die with a novel feeding structure.
Background
The aluminium alloy motorcycle wheel structure consists of a rim, a spoke and a middle hub, and the current aluminium alloy rim is generally molded by adopting a gravity center casting process.
FIG. 3 is a cross-sectional view of an existing motorcycle hub, where a riser is now added above the casting mold of the hub, and then the riser is fed according to gravity, resulting in a small feeding channel between the hub spoke cavity and the riser of the existing casting mold due to the special shape of the hub spoke itself, affecting the feeding quality to the hub spoke portion, so that the internal tissue of the hub spoke has loose defects all the time.
In view of this, a gravity casting mold of a novel feeding structure is proposed.
Disclosure of Invention
In order to overcome the defects in the prior art, the utility model aims to provide a gravity casting die with a novel feeding structure.
The technical scheme adopted by the utility model is as follows: the gravity casting die with the novel feeding structure comprises an upper die core, wherein a casting cavity meeting the requirement of a casting hub is arranged on the bottom surface of the upper die core, and a plurality of inwards concave molten aluminum flow channels are annularly arranged on the outer end surface of the lower side of the upper die core; the lower side of the molten aluminum runner is communicated with the end faces of a plurality of hub spoke cavities in the casting cavity and is used for expanding the feeding path of the hub spoke cavities in the casting cavity.
In a preferred embodiment, a riser is correspondingly arranged on the upper mold core above the molten aluminum runner.
In a preferred embodiment, an orifice ring is arranged between the upper mold core and the riser on the upper mold core.
In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows: the aluminum liquid flow channels are arranged at the positions, close to the end faces of the spoke cavities of the wheel hub, of the bottom face of the upper mold core, and the aluminum liquid flow channels are designed to widen the channels between the riser and the casting cavity, so that aluminum liquid on the riser can flow onto the casting cavity more easily, the feeding quality is improved, the quality of the internal structure of the wheel rim is improved, and the problem of loose defects in the casting of the wheel hub can be solved while the structure and the cost are not increased additionally.

FIG. 2 is a schematic illustration of the overall cross-sectional plan view of the present utility model;
FIG. 3 is a cross-sectional plan view of a prior art hub.
The marks in the figure: 1-upper mold core, 2-casting cavity, 3-riser, 4-molten aluminum runner and 5-orifice ring.
Detailed Description
The utility model will be described in further detail below with reference to examples and with reference to the accompanying drawings.
1-3, the gravity casting mould with a novel feeding structure comprises an upper mould core 1, wherein a casting cavity 2 meeting the requirement of a casting hub is arranged on the bottom surface of the upper mould core 1, and a plurality of inwards concave molten aluminum channels 4 are annularly arranged on the outer end surface of the lower side of the upper mould core 1; the downside of aluminium liquid runner 4 is linked together with a plurality of hub spoke die cavity terminal surfaces department in casting die cavity 2, the top of aluminium liquid runner 4 corresponds on last mold core 1 and is equipped with riser 3, go up mold core 1 bottom surface and be close to hub spoke die cavity terminal surface department and all be equipped with aluminium liquid runner 4, the design effect of aluminium liquid runner 4 is through having widened the passageway between riser 3 and casting die cavity 2 for aluminium liquid on the riser 3 flows more easily on the casting die cavity 2, the quality of feeding has been promoted, thereby the quality after the rim shaping has been promoted, loose defect's problem when not additionally increasing structure and cost can also be solved in the wheel hub casting.
Further, the aluminum runner 4 and the hub spoke cavities are preferably designed to be twenty-one.
In the molding, the upper mold core 1 is cast in combination with a lower mold core (not shown).
In the embodiment, an orifice ring 5 is arranged between the upper mold core 1 and the riser 3 on the upper mold core 1, and the overflow of aluminum liquid in the riser 3 can be prevented by the orifice ring 5.
The aluminum liquid flow channels 4 are arranged on the bottom surface of the upper mold core 1 and close to the end surfaces of the spoke cavities of the wheel hub, the aluminum liquid flow channels 4 are designed to widen the channels between the riser 3 and the casting cavity 2, so that aluminum liquid on the riser 3 flows onto the casting cavity 2 more easily, the feeding quality is improved, and the quality of the formed wheel rim is improved.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
