Description
Technical field
The present invention relates to the designs and making of machine casting industry mold, primarily directed to a kind of casting of component of machine
Mold, specifically a kind of piston type product mold.
Background technology
Currently, in the piston type of tradition machinery industry makes, however it remains many problems, since its weight is larger,
Thickness difference between peripheral position and bottom is also larger, so that in piston type die casting, in the big place of thickness, example
If wherein bottom is susceptible to shrinkage porosite or shrinkage cavity, process outlet rate is low, has seriously affected the production cost and casting quality of casting,
The waste of the energy is also brought simultaneously.
Invention content
The object of the present invention is to provide one kind capable of thoroughly solving piston type casting, shrinkage cavity and work occurs when producing casting
The technical solution of skill yield rate problem.
In order to realize the present invention, using following technical scheme：A kind of piston type product mold, including pressure plate and back-pressure
Plate；Two groups of casting mold core groups are respectively equipped on pressure plate and counter, every group of casting mold core group includes two symmetrically arranged castings
Part mold core, casting mold core are connected by riser；Counter is equipped with top sprue, top cross gate and lower part cross gate,
Pressure plate is equipped with lower part sprue, sprue cup and ingate；After pressure plate and back-pressure plate moulding when mould assembling, top sprue connects
Logical lower part sprue, top sprue edge are connected to sprue cup, and top sprue carries out back-pressure with lower part sprue, and lower part is perpendicular
Running channel carries out back-pressure with top cross gate and lower part cross gate, and ingate carries out with top cross gate and lower part cross gate anti-again
Pressure；The bottom for the casting mold core that ingate is arranged on pressure plate；It is equipped with sand core at the top of casting mold core in counter；Lower part is perpendicular
Running channel bottom is equipped with dreg collecting slot.
Further, the preferred draft oblique angle of the casting mold core is 2-5 degree, and casting mold core is higher than close to sand core one end to be leaned on
One end of nearly ingate.
Further, the riser is cold riser, and shape is circular cylindrical shape.
Further, graphite powder is added in sand core.
When cast, molten iron is poured into from sprue cup, by top running channel again with lower part sprue is counter take after, lower part sprue is again
With upper and lower part cross gate is counter taken after enter ingate, the riser for entering back into mold core and being connected to mold core.In riser and graphite
Under the action of, it can effectively avoid the larger position of casting thickness and the phenomenon that pine contracting and shrinkage cavity occur.
Beneficial effects of the present invention：The present invention can effectively solve the problems such as casting shrinkage cavity is low with product yield, can be into one
Step improves the consistency of casting, significantly improves the feeding efficiency and casting yield rate of riser, improves enterprise product quality.
Description of the drawings
Fig. 1 is pressure plate of the present invention and schematic diagram when mould assembling after back-pressure plate moulding.
Fig. 2 is pressure plate schematic diagram of the present invention.
Fig. 3 is counter schematic diagram of the present invention.
Specific implementation mode
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1, Figure 2 and Figure 3, a kind of piston type product mold, including pressure plate 1 and counter 2；1 He of pressure plate
Two groups of casting mold core groups are respectively equipped in counter 2, every group of casting mold core group includes two symmetrically arranged casting mold cores 6, casting
Part mold core 6 is connected by riser 5；Counter 2 is equipped with top sprue 4, top cross gate 7 and lower part cross gate 8, positive pressure
Plate 1 is equipped with lower part sprue 12, sprue cup 3 and ingate 10；After pressure plate 1 and 2 moulding of counter when mould assembling, top is perpendicular to pour
Road 4 is connected to lower part sprue 12, and sprue 4 edge in top is connected to sprue cup 3, top sprue 4 and lower part sprue 12 into
Row back-pressure, lower part sprue 12 and top cross gate 7 and lower part cross gate 8 carry out back-pressure, ingate 10 again with top cross gate 7
Back-pressure is carried out with lower part cross gate 8；The bottom of the casting mold core 6 on pressure plate 1 is arranged in ingate 10；Casting in counter 2
6 top of part mold core is equipped with sand core 11；Sprue 12 bottom in lower part is equipped with dreg collecting slot 9.
The 6 preferred draft oblique angle of casting mold core is 2-5 degree, and casting mold core 6 is close to 11 one end of sand core higher than close
One end of ingate 10.
The riser 5 is cold riser, and shape is circular cylindrical shape；Graphite powder is added in the sand core 11.
When cast, molten iron is poured into from sprue cup, by top running channel again with lower part sprue is counter take after, lower part sprue is again
With upper and lower part cross gate is counter taken after enter ingate, the riser for entering back into mold core and being connected to mold core.In riser and graphite
Under the action of, it can effectively avoid the larger position of casting thickness and the phenomenon that pine contracting and shrinkage cavity occur.
Part that the present invention does not relate to is the same as those in the prior art or can be realized by using the prior art.
