Abstract

The utility model discloses a die-casting die provided with a local pressing device, which comprises a die body having a mould cavity for shaping and cooling a casting. The die is characterized in that: a pressing core is disposed in the mould cavity; the pressing core is connected with a power device, and can move within a certain range driven by the power device; and the front of the pressing core is faced to a thick wall position. For the die-casting die provided with a local pressing device of the utility model, when metal liquid is in semiconsolidated state, the power device drives the pressing core to move to act on the casting at the position with thicker wall, to cause the texture of the position to be more compact, thereby avoids the defects of loosening, stomata or shrinkage. Thereby the die of the utility model can improve the internal quality, qualified rate and air-tightness of the casting produce effectively.

Description

Be provided with the die casting of local pressurizing unit
Technical field
The utility model relates to the mould that a kind of casting field is used, and especially is provided with the die casting of local pressurizing unit.
Background technology
Mould is the important and crucial parts of Foundry Production, directly determines the external geometric overall dimension and the inner Forming Quality of foundry goods, makes foundry goods avoid occurring such as mass defects such as loose, bubble, slag inclusions; In when casting, adopt the manufacture method of extruding die cast usually, the metal liquid that has melted is injected cooling forming in the mold cavity down at certain pressure (pressurizeing with pressure head).Some die cast part is easy to generate defectives such as loose, pore or shrinkage cavity at cooling stage, reduce the performance of part, even foundry goods is scrapped.In order to solve the ubiquitous above-mentioned defective of foundry goods, people propose and have adopted several different methods to solve foregoing problems, cast, in die cavity, be provided with feeding cap mouth etc. as compression casting, vacuum pressed, reached certain effect, but can not address the above problem fully, can not eliminate the above-mentioned defective that foundry goods exists fully.Especially the part of having relatively high expectations for some self air-tightness, and the parts locally wall thickness is thicker, as air-conditioning product, automobile valve body product etc., because the area at the position that its local wall thickness is thicker, wall thickness is thicker is bigger, just more be easy to generate defectives such as loose, pore or shrinkage cavity at the wall thickness position, especially be easy to generate subcutaneous loose or pore, reduce processing characteristics, reduce its air-tightness, the qualification rate of product is reduced significantly.
Summary of the invention
The utility model is easy to generate defectives such as loose, pore or shrinkage cavity at self of the prior art foundry goods that air-tightness is had relatively high expectations, local wall thickness is thicker, reduce processing characteristics, reduce deficiency such as its air-tightness, provide a kind of and can prevent effectively that it from producing the die casting that is provided with local pressurizing unit of defectives such as loose, pore or shrinkage cavity.
The technical solution of the utility model: be provided with the die casting of local pressurizing unit, comprise die ontology, die cavity is arranged in die ontology, foundry goods is cooling forming in die cavity; It is characterized in that: the extruding core is set in die cavity, and the extruding core is connected with power set, moves within the specific limits under power set drive.
Further feature is: the front end of described extruding core is over against the heavy wall position of foundry goods.
Described power set are hydraulic jack or cylinder or motor.
The utility model is provided with the die casting of local pressurizing unit, with respect to prior art, has following characteristics:
1, when metal liquid is in half curdled appearance, drive the extruding core by power set and move, make the extruding core act on the thicker position of wall thickness of foundry goods, make the dense structure at the thicker position of wall thickness of foundry goods, avoid producing defectives such as loose, pore or shrinkage cavity.
2, effectively improve the internal soundness of foundry goods, the qualification rate of raising product, improve the air-tightness of product.
3, simple in structure, easy to operate.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Fig. 1 is the utility model mould structure schematic diagram.
The specific embodiment
In Fig. 1, the utility model is provided with the die casting of local pressurizing unit, comprises die ontology 1, the die cavity 2 according to technological requirement design, making is arranged, described foundry goods 3 cooling forming in die cavity 2 in die ontology 1; Improvements of the present utility model are that extruding core 4 is set in die cavity 2, and extruding core 4 is connected with power set 5, moves within the specific limits under power set 5 drive.The front end of extruding core 4 is over against the thicker position of the wall thickness of foundry goods 3, extruding core 4 is under power set 5 drive, the wall thickness that its front end acts on foundry goods 3 thicker (heavy wall) position, or the demanding position of air-tightness, or other need use the position of extruding core 4 extra extrusion modlings.
Power set 5 of the present utility model are the hydraulic jack or the power part commonly used such as cylinder or motor of prior art, produce displacement during its work, drive connected extruding core 4 and move.
The course of work of the present utility model: behind die ontology 1 matched moulds, as requested metal liquid (aluminium liquid, molten steel, magnesium alloy liquid etc.) is injected in the die cavity 2, can adopt the mode of pressurization die casting to inject in the die cavity 2 in case of necessity; Metal liquid cooled and solidified and obtain foundry goods 3 in die cavity 2, after after a while, when metal liquid is in half curdled appearance, start power set 5, power set 5 drive extruding core 4 and produce certain displacement, the front end of extruding core 4 acts on thicker, the demanding position of air-tightness of wall thickness of foundry goods 3, the be squeezed pressure of core 4 front ends of the metal liquid that makes foundry goods 3 these positions be in half curdled appearance, it is solidified is under the pressurized state, can make the dense structure at this position, improve the internal soundness of this position and even whole foundry goods 3.
