Abstract
The utility model discloses a pressure-casting mold of a speed changer shell, mainly comprising a fixed die, a fixed die plate, a movable die, a movable die plate, an ejecting mechanism and a casting system, wherein the mold adopts a whole pressure chamber; the movable die is provided with a reversing operation side sliding block, a balance locking block and a top side sliding block; and the fixed die is provided with a reversing operation locking block and a top side locking block. The pressure-casting mold has more side drawing sliding blocks, casts processing holes on the side surface, and eliminates the pore defects of the processing surface; and a casting system consisting of a cross pouring gate, an inner sprue, an overflowing groove and a vacuumizing system guarantees the normal production of castings.
Description
Technical field
The utility model relates to a kind of case of transmission die casting.
Background technology
Shrinkage cavity, shrinkage porosite is the common internal flaw of a kind of die casting, in the process of setting of foundry goods, because of can not get the molten metal compensation, the generation contraction causes the hole, different with internal porosity, the shrinkage cavity rough surface, concentrate greatly and be shrinkage cavity, small and scattered is shrinkage porosite, appears at mostly away from ingate, the heavy wall thermojunction position that wall thickness change is bigger, shrinkage cavity, shrinkage porosite directly reduces casting strength, the withstand voltage experiment of foundry goods is leaked, gas leakage, the cavity appears in machined surface, causes foundry goods defective, and original die casting is because core-pulling mechanism is provided with less, increased foundry goods heavy wall thermojunction, made the foundry goods key position phenomenon of shrinkage cavity occur.
The utility model content
The purpose of this utility model provides a kind of cast(ing) surface of avoiding and shrinkage cavity, shrinkage porosite phenomenon occur, reduces the mould set-up time, the case of transmission die casting of enhancing productivity.
The technical scheme that the utility model is adopted for achieving the above object is: the case of transmission die casting, mainly comprise cover half, solid plate, dynamic model, moving platen, liftout plate and running gate system, mould adopts the whole chamber of pressing, described dynamic model is provided with anti-fore side slide block, balance latch segment and day side slide, and described cover half is provided with anti-fore side latch segment and day side latch segment.
Described running gate system is made up of cross gate, ingate, overflow launder and pumped vacuum systems.
Described running gate system is provided with the branch flow cone.
Described anti-fore side slide block is provided with anti-fore side take-up housing and anti-fore side cylinder bracket.
Described solid plate is provided with fore side cylinder bracket and fore side oil cylinder.
Side slide was provided with day sideslip block and day side cylinder support in described day.
It is many that the utility model case of transmission die casting side is taken out slide block, and the side machining hole is cast out, eliminated the gas hole defect of finished surface; The casting system of being made up of cross gate, ingate, overflow launder, pumped vacuum systems has guaranteed the ordinary production of foundry goods.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the utility model case of transmission die casting dynamic model structure chart;
Fig. 2 is the utility model case of transmission die casting cover half structure chart;
