Description
Technical field
The utility model relates to high voltage precision foundry engieering, in particular to a kind of stomata shaping mechanism for die casting.
Background technique
Ancient Times in China, prince's noon ancient cooking vessel, copper taboo, copper lion etc., are all the masterpiece of casting, and from the 1940s, casting is used for
After industrial production, so far, casting is developed with faster speed always, and especially into 21 century, China develops very
Rapidly, large quantities of foundry engieering richnesses enterprise is emerged.
As casting accuracy and cast article mechanical property requirements are higher and higher, high-pressure casting is had become in casting industry
Bellwether, high pressure cast, which is made, is mainly used for the industries such as automobile, aviation, is also applied to other all industrial departments, predominantly weapons, energy
The industries such as source, communications and transportation, light industry, weaving, pharmacy, medical instrument, pump and valve, as high-pressure casting is using more and more,
The product category of casting and forming is more and more abundant, and product structure becomes increasingly complex, and leads to certain performances (internal soundness) of product
Drawing requirement is not achieved, it is second-rate especially to show as internal porosity, and the usual core pulling pin of traditional internal porosity processing technique,
After forming, when die casting machine is opened, core pulling pin can retreat together with framed, and the processing method of this pulled core structure, can lead
It causes air hole structure that can change as pulled core structure is extracted out, easily causes clogging.
Utility model content
The utility model is mainly solving the technical problems that provide a kind of stomata shaping mechanism for die casting, Neng Gou great
Width improves the molding quality of stomata, prevents from causing qualification rate to reduce due to air-hole blockage.
In order to solve the above technical problems, the technical solution that the utility model uses is: providing a kind of for die casting
Stomata shaping mechanism, comprising: the framed and underlying mode being located above；
The framed inside is fixedly installed with oil cylinder and link block, the oil cylinder bottom and the link block stationary phase
Even, moving up and down for link block is realized；
Squeeze pin is fixedly installed in the link block, the squeeze pin penetrates the mode, realizes the extruding of squeeze pin
Punching；
Casing pressing plate is installed, described sleeve pipe pressing plate is tightly attached to the framed bottom, limits the link block in the mode
Depressed position.
In one preferred embodiment of the utility model, it is described it is framed in be also fixedly installed with guide pad.
In one preferred embodiment of the utility model, the guide pad is fixedly connected on the oil cylinder and described sleeve pipe pressure
Between plate.
In one preferred embodiment of the utility model, the guide pad is located at the two sides of the link block.
The beneficial effects of the utility model are: a kind of stomata shaping mechanism for die casting of the utility model, by adopting
Original core pulling pin is substituted with squeeze pin, and drives the link block for being fixed with squeeze pin to move up and down by oil cylinder, from
And realize the air-pressure forming of cylinder, compared to core-pulling mechanism, the molding quality of stomata greatly improved, and can prevent due to
Air-hole blockage and cause qualification rate to reduce.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model in a preferred embodiment；
The components in the drawings are labeled as follows: 1, framed, 2, mode, 11, oil cylinder, 12, link block, 13, squeeze pin, 14,
Guide pad, 21, casing pressing plate.
Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear
Define.
Referring to Fig. 1, the utility model embodiment includes:
A kind of stomata shaping mechanism for die casting, comprising: framed 1 and underlying mode 2 being located above；
Oil cylinder 11 and link block 12,11 bottom of oil cylinder and the link block are fixedly installed with inside described framed 1
12 are fixedly linked, and realize moving up and down for link block 12；
Squeeze pin 13 is fixedly installed in the link block 12, the squeeze pin 13 penetrates the mode 2, realizes squeeze pin
13 extruding punching；
Casing pressing plate 21 is installed, described sleeve pipe pressing plate 21 is tightly attached to framed 1 bottom, described in limitation in the mode 2
The depressed position of link block 12.
It further illustrates, guide pad 14 is also fixedly installed in described framed 1, and the guide pad 14 is fixedly connected on described
Between oil cylinder 11 and described sleeve pipe pressing plate 21, the guide pad 14 is located at the two sides of the link block 12, can pass through guide pad
The arcuate path that 14 restriction link blocks 12 move up and down.
Further illustrate, the utility model discloses a kind of stomata shaping mechanism for die casting, groundwork
Principle is as follows:
(1) squeeze: after die casting machine injection, molten aluminum starts to cool down, and is transformed into semisolid (viscous pasty state) from liquid, presses at this time
Casting machine sends an execution signal to oil cylinder, and oil cylinder 11 pushes, and pushes squeeze pin 13 along guiding under the action of link block 12
Block 14 is pressed down against, and squeeze pin 13 forms stomata after penetrating mode 2.
(2) reset: after completing stomata molding, die casting machine sends a reset signal to oil cylinder 11, and oil cylinder 11 moves up multiple
Position drives squeeze pin 13 to reset upwards along guide pad 14 under the action of link block 12, so that completion is primary to squeeze process；Weight
Multiple above-mentioned steps, can be realized to the continuously shaped of multiple stomatas.
It is different from the prior art, a kind of stomata shaping mechanism for die casting of the utility model, by using squeeze pin
Original core pulling pin is substituted, and drives the link block for being fixed with squeeze pin to move up and down by oil cylinder, to realize gas
The molding quality of stomata greatly improved compared to core-pulling mechanism in the air-pressure forming of cylinder, this region internal soundness (stomata) is qualified
Rate is promoted to 99.1% by 72%, and can prevent from causing qualification rate to reduce due to air-hole blockage.
In the description of the present invention, it should be noted that term " on ", "lower", "left", "right", "inner", "outside" etc.
The orientation or positional relationship of instruction be based on the orientation or positional relationship shown in the drawings or the utility model product use when
