Abstract
The utility model relates to the field of casting modeling of extrusion dies, in particular to a camshaft bracket casting die with a local extrusion device. The camshaft bracket casting die with the local extrusion device comprises a die body (1), wherein the die body (1) is formed by splicing a static die (11) and a moveable die (12); and a hollow cavity is formed after the static die (11) and the moveable die (12) are spliced. The camshaft bracket casting die with the local extrusion device is characterized by also comprising an oil cylinder (2), a piston (3) and a pressurizing rod (4), wherein one end of the piston (3) is hermetically connected with the oil cylinder (2) and the other end of the piston (3) is connected with the pressurizing rod (4); and the other end of the pressurizing rod (4) is propped against the moveable die (12) of the die body (1). The camshaft bracket casting die with the local extrusion device has compact casts, long service life and high qualified rate.
Description
Technical field
The utility model relates to the casting and molding field with extrusion die, is specially a kind of camshaft stand casting mould that is used to have local pressurizing unit.
Background technology
The support of engine cam comprises a bearing guard in order to supporting cam wheel on the support, because the support shape is complicated, adopt casting usually.Because the bearing guard end projection area of camshaft stand is bigger, the casting back is prone to produce shrinkage porosite, shrinkage cavity defect when the molten metal condensation, and the sealing of having destroyed foundry goods causes foundry goods to be scrapped, and is difficult to improve the quality through improving casting system.
The utility model content
In order to overcome the defective of prior art, the mould that a kind of foundry goods is fine and close, yield rate is high is provided, the utility model discloses a kind of camshaft stand casting mould that has local pressurizing unit.
The utility model reaches goal of the invention through following technical scheme:
A kind of camshaft stand casting mould that has local pressurizing unit; Comprise mold, mold is put together by quiet mould and dynamic model, the inner die cavity that forms hollow after quiet mould and the dynamic model amalgamation; It is characterized in that: also comprise oil cylinder, piston and booster rod; One end of piston is connected with cylinder seal, and the other end of piston connects booster rod, and the other end of booster rod is against on the dynamic model of mold.
The described camshaft stand casting mould that has local pressurizing unit is characterized in that: comprise that also booster set, booster set are enclosed within outside the booster rod, booster rod and booster set form matched in clearance.
When the utility model uses; Quiet mould and dynamic model are pieced together mold, and mold is placed on the die casting machine, make booster rod withstand the dynamic model of mold; In die casting, start oil cylinder; Through piston and booster rod dynamic model is exerted pressure, oil cylinder adopts the action of oil pressure oil-feed oil return control booster rod, reaches the effect of extruding feeding through booster rod.The beneficial effect of the utility model is: foundry goods dense internal organization, porosity are controlled less than 6%; Good airproof performance; Reduce casting system because of flinging the erosion that phenomenon produces, prolonged die life; Qualification rate is not less than 96%.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below further specify the utility model through specific embodiment.
Embodiment 1
A kind of camshaft stand casting mould that has local pressurizing unit; Comprise mold 1 oil cylinder 2, piston 3 and booster rod 4, as shown in Figure 1, concrete structure is: mold 1 is put together with dynamic model 12 by quiet mould 11; The inner die cavity that forms hollow after quiet mould 11 and dynamic model 12 amalgamations; One end and the oil cylinder 2 of piston 3 are tightly connected, and the other end of piston 3 connects booster rod 4, and the other end of booster rod 4 is against on the dynamic model 12 of mold 1.For protection booster rod 4, outside booster rod 4, also be with booster set 5, booster rod 4 forms matched in clearance with booster set 5.
When present embodiment uses; Quiet mould 11 is pieced together mold 1 with dynamic model 12, and mold 1 is placed on the die casting machine, make booster rod 4 withstand the dynamic model 12 of mold 1; In die casting, start oil cylinder 2; Exert pressure through piston 3 and 4 pairs of dynamic models 12 of booster rod, oil cylinder 2 adopts the action of oil pressure oil-feed oil return control booster rod 4, reaches the effect of extruding feeding through booster rod 4.
