Description
Technical field
The utility model relates to the designs and production of machine casting industry mold, primarily directed to a kind of component of machine
Casting mould, specifically a kind of piston type product mold.
Background technique
Currently, tradition machinery industry piston type production in, 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 easy to appear 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.
Utility model content
The purpose of the utility model is to provide one kind can thoroughly solve piston type casting, shrinkage cavity occurs when producing casting
With the technical solution of product yield problem.
In order to realize the utility model, using following technical scheme: a kind of piston type product mold, including pressure plate and anti-
Pressing 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
Casting mold core, casting mold core are connected by riser；Counter is equipped with top sprue, top cross gate and lower lateral and pours
Road, pressure plate are equipped with lower part sprue, sprue cup and ingate；After pressure plate and back-pressure plate moulding when mould assembling, top is perpendicular to be poured
Road is connected to lower part sprue, and top sprue edge is connected to sprue cup, and top sprue and lower part sprue carry out back-pressure, under
Portion's sprue and top cross gate and lower part cross gate carry out back-pressure, and ingate is carried out with top cross gate and lower part cross gate again
Back-pressure；The bottom of the casting mold core on pressure plate is arranged in ingate；Sand core is equipped at the top of casting mold core in counter；Lower part
Sprue 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 casting, 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 biggish position of casting thickness and the phenomenon that pine contracting and shrinkage cavity occur.
The utility model has the beneficial effects that the utility model can be solved effectively, casting shrinkage cavity is low with product yield etc. to be asked
Topic, can further improve the consistency of casting, significantly improve the feeding efficiency and casting yield rate of riser, improve enterprise product
Quality.
Detailed description of the invention
Schematic diagram when Fig. 1 is mould assembling after the utility model pressure plate and back-pressure plate moulding.
Fig. 2 is the utility model pressure plate schematic diagram.
Fig. 3 is the utility model counter schematic diagram.
Specific embodiment
The utility model is further described 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 be poured
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
Sand core 11 is equipped at the top of part mold core 6；Sprue 12 bottom in lower part is equipped with dreg collecting slot 9.
The preferred draft oblique angle of casting mold core 6 is 2-5 degree, and casting mold core 6 is higher than close close to 11 one end of sand core
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 casting, 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 biggish position of casting thickness and the phenomenon that pine contracting and shrinkage cavity occur.
The parts not involved in the utility model is the same as those in the prior art or can be realized by using the prior art.
