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 middle case class product mold.
Background technology
Currently, tradition machinery industry middle case class make in, however it remains many problems, due to its weight compared with
Greatly, the thickness difference between center and bottom is also larger, so that in middle case class die casting, on the big ground of thickness
Side, such as wherein big planar base are susceptible to shrinkage porosite or stomata, and process outlet rate is low, has seriously affected the production cost of casting
With casting quality, while the waste of the energy is also brought.
Invention content
The object of the present invention is to provide one kind capable of thoroughly solving middle case class casting, produce cast when occur shrinkage cavity,
The technical solution of stomata and product yield problem.
In order to realize the present invention, using following technical scheme：A kind of middle case class 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, the big plane top of each casting mold core are equipped with the riser being connected with casting mold core, under the big plane of casting mold core
Portion is equipped with the ingate being connected；Counter is equipped with sprue one, sprue three, and pressure plate is equipped with sprue two, perpendicular to pour
The top edge in road one is connected with sprue cup；After pressure plate and back-pressure plate moulding when mould assembling, sprue one is connected to sprue two,
Sprue two and sprue tee joint, sprue three carry out back-pressure with cross gate, and ingate carries out back-pressure with cross gate；Pressure plate
It is equipped with exhaust piece, the casting mold core group that exhaust piece is arranged close on pressure plate, but is not attached to；Two castings in casting mold core group
Sand core is equipped between part mold core；Casting mold core is surrounded by venting plug；Three middle part of sprue is equipped with filter, and sprue three is most
Lower end is equipped with dreg collecting slot.
Further, it is more smooth to be conducive to exhaust when sand is penetrated in moulding for the application of venting plug, while allowing to penetrate sand closer.
Further, the thickness of the exhaust piece is 2.5-3mm, the row of cavity when being more advantageous to cast in this section
Gas.
Further, the preferred draft oblique angle of the casting mold core is 2-5 degree, and casting mold core is higher than close to riser one end to be leaned on
One end of nearly ingate.
Further, the riser is cold riser, and shape is round riser.
Further, graphite powder is added in the sand core.
When cast, molten iron is poured into from sprue cup, and after entering back into filter by sprue, sprue is carried out with cross gate again
It is counter take after enter ingate, the riser for entering back into mold core and being connected to mold core.Under the action of riser and graphite, it can effectively avoid
There is the phenomenon that pine contracting and shrinkage cavity in the larger position of casting thickness.
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 schematic diagram of the present invention.
Fig. 2 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 depicted in figs. 1 and 2, a kind of middle case class product mold, including pressure plate 1 and counter 2；Pressure plate 1 and anti-
Two groups of casting mold core groups are respectively equipped on pressing plate 2, every group of casting mold core group includes two symmetrically arranged casting mold cores 3, each
The big plane top of casting mold core 3 is equipped with the riser 7 being connected with casting mold core, and the big planar lower of casting mold core 3 is equipped with phase
The ingate 8 of connection；Counter 2 is equipped with sprue 1, sprue 36, and pressure plate 1 is equipped with sprue 25, sprue
One 4 top edge is connected with sprue cup 9；After pressure plate 1 and 2 moulding of counter when mould assembling, sprue 1 and sprue 25
Connection, sprue 25 be connected to sprue 36, sprue 36 and the progress back-pressure of cross gate 10, ingate 8 and cross gate 10 into
Row back-pressure；Pressure plate 1 is equipped with exhaust piece 11, the casting mold core group that exhaust piece 11 is arranged close on pressure plate 1, but is not attached to；
Sand core 13 is equipped between two casting mold cores 3 in casting mold core group；Casting mold core 3 is surrounded by venting plug 15；Sprue
36 middle parts are equipped with filter 14, and 36 bottom of sprue is equipped with dreg collecting slot 12.
The thickness of the exhaust piece 11 is 2.5-3mm, the exhaust of cavity when being more advantageous to cast in this section.
The 3 preferred draft oblique angle of casting mold core is 2-5 degree, and casting mold core 3 is higher than close to 7 one end of riser close to interior
One end of cast gate 8.
The riser 7 is cold riser, and shape is round riser；Graphite powder is added in the sand core 6.
When cast, molten iron is poured into from sprue cup, and after entering back into filter by sprue, sprue is carried out with cross gate again
It is counter take after enter ingate, the riser for entering back into mold core and being connected to mold core.Under the action of riser and graphite, it can effectively avoid
There is the phenomenon that pine contracting and shrinkage cavity in the larger position of casting thickness.
