Abstract

The utility model relates to an engine oil pan die-casting mold. The engine oil pan die-casting mold comprises an oblique core pulling mechanism and a side core pulling mechanism, and also comprises a fixed mold plate and a fixed mold core pulling mechanism, wherein the fixed mold plate is fixedly arranged on a fixed mold frame; the fixed mold core pulling mechanism comprises an oil cylinder, an oil cylinder connector and a core pulling mechanism; a rear end cover of the oil cylinder is fixedly arranged on the fixed mold plate; a piston rod of the oil cylinder is connected with an oil cylinder suspension groove of the oil cylinder connector and compressed through an oil cylinder connector pressure block which is arranged on the oil cylinder connector; the core pulling structure is arranged in a cavity of a fixed mold, connected with the core pulling suspension groove of the oil cylinder connector and limited by a core pulling stop block which is arranged on the oil cylinder connector. The fixed mold core pulling mechanism is arranged in an oil scaleplate hole of an engine oil pan on the mold and used for die-casting forming the oil scalpelate hole of the engine oil pan, so that the technical problem of an oil scaleplate hole product which is mechanically machined that multiple air pores exist and the air leakage is severe.

Description

Engine Oil Disc die casting
Technical field
The utility model relates to a kind of Engine Oil Disc die casting, particularly a kind of Engine Oil Disc die casting that can loose core by cover half.
Background technology
As Figure 1-4, Engine Oil Disc compression mod die joint complexity, envelope liquid aluminum is many, and it is provided with oblique core drawing mechanism 10 in P1 direction, three angles of oblique core drawing mechanism 10 and basal plane folder; Be provided with side core-pulling mechanism 11 in P2, P3 direction.Consider the design difficulty of mould structure, oil pan die casting 13 does not arrange core-pulling mechanism in the oil scale hole at P4 place, and after the die casting of oil pan die casting completes, two oil scale holes at P4 place need to be by machined moulding.
Although above-mentioned existing Engine Oil Disc die casting has reduced the difficulty of loosing core of compression mod, but because oil pan die casting is that die-casting becomes under high pressure, fast state, can there is unavoidably pore in its inside, two oil scale apertures at oil pan die casting P4 place are crossed after machined, and oil pan die casting exists the defects such as pore is many, product gas leakage is serious, qualification rate is low.
Utility model content
In prior art, Engine Oil Disc die casting does not arrange core-pulling mechanism at the oil scale hole place of oil pan, the oil scale aperture of oil pan die casting is crossed after machined, there is the technical problem that pore is many, gas leakage is serious, qualification rate is low in product, the purpose of this utility model is to provide a kind of Engine Oil Disc die casting, this die casting arranges core-pulling mechanism by the oil scale hole place at oil pan, realize the loosing core of oil pan die casting, solved and caused by machining mode processing oil staff guage hole that product air holes is many, the serious technical problem of leaking gas.
To achieve these goals, the technical solution of the utility model is:
A kind of Engine Oil Disc die casting, comprises oblique core drawing mechanism and side core-pulling mechanism, also comprises:
Solid plate, it is fixedly installed on cover half frame;
Cover half core-pulling mechanism, it comprises oil cylinder, cylinder connector and pulled core structure;
The rear end cap of described oil cylinder is fixedly installed on solid plate;
The piston rod of oil cylinder is connected with the oil cylinder hanging groove of cylinder connector, and compresses by the cylinder connector briquetting being arranged on cylinder connector;
Described pulled core structure is arranged in the cavity of cover half, is connected with the hanging groove of loosing core of cylinder connector, and spacing by being arranged on the block of loosing core on cylinder connector.
Further, described solid plate is positioned on cover half frame by positioning key, and is fixedly connected with cover half frame by bolt.
Further, the rear end cap of described oil cylinder and solid plate are bolted to connection; Cylinder connector briquetting is connected by screw with loose core block and cylinder connector.
Useful technique effect of the present utility model is:
Engine Oil Disc die casting of the present utility model, oil scale hole place by oil pan on mould arranges cover half core-pulling mechanism, by the oil scale hole die cast of oil pan, solve by machined oil scale hole, product exists that pore is many, the serious technical problem of leaking gas.Utilize Engine Oil Disc die casting of the present utility model now to complete batch production, constant product quality, meets technological requirement.
