Description
Technical field
The present invention relates to a kind of high voltage precision foundry engieering, in particular to a kind of bilateral charging for camshaft the cover is poured
Casting mould.
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.
Wherein, camshaft the cover is one of the representative in die casting, cast used by mold be all often it is unilateral into
Expect mold, it may be assumed that melt is fed along the side of product after casting, and the structure during casting due to cast flow velocity
Not enough, lead to the phenomenon that beginning to cool down during casting, that is, will appear internal condensate and in advance shrinkage, to lead
Cause interiors of products obtained by casting second-rate, especially stomata is more, and qualification rate is low, very the influence delivery cycle.
Summary of the invention
The invention mainly solves the technical problem of providing a kind of bilateral charging casting die for camshaft the cover, energy
Enough bilateral chargings realized to camshaft the cover are cast, and the increased quality of (stomata) inside camshaft the cover can be conducive to, whole
Body qualification rate is high.
In order to solve the above technical problems, one technical scheme adopted by the invention is that: it provides a kind of for camshaft the cover

It is connected with the left feed channel, the right runner is connected with the right feed channel, and the left shunt road and the right shunting
Road intersection, the intersection are connected to the sprue gate and realize bilateral charging.
In a preferred embodiment of the present invention, the left feed channel is made of several left branch flow passages being parallel to each other.
In a preferred embodiment of the present invention, it is connected on the left of each left branch flow passage and the die cavity.
In a preferred embodiment of the present invention, the right feed channel is made of several right branch flow passages being parallel to each other.
In a preferred embodiment of the present invention, it is connected on the right side of each right branch flow passage and the die cavity.
In a preferred embodiment of the present invention, the left branch flow passage and the right branch flow passage are in same level section.
In a preferred embodiment of the present invention, the die body surface is also equipped with multiple cinder ladles.
In a preferred embodiment of the present invention, each cinder ladle and the type chamber are interconnected.
The beneficial effects of the present invention are: a kind of bilateral charging casting die for camshaft the cover of the present invention, by adopting
The connection at sprue gate and internal die cavity is realized with bilateral charging running channel, so that after melt is poured into from sprue gate, Neng Goutong
Cross bilateral while to being poured in die cavity, the poring rate of quickening casts products obtained therefrom compared to existing unilateral charging
Internal soundness (stomata) be increased dramatically, qualification rate is high, high production efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the present invention in a preferred embodiment；
The components in the drawings are labeled as follows: 1, sprue gate, 2, left shunt road, 3, right runner, 4, left feed channel, 5, right charging
Road, 6, left branch flow passage, 7, right branch flow passage, 8, cinder ladle, 9, die cavity.
Specific embodiment
The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawing, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
Referring to Fig. 1, the embodiment of the present invention includes:
A kind of bilateral charging casting die for camshaft the cover, comprising: die body offers die cavity 9, institute inside the die body
The outside for stating die body is equipped with sprue gate 1, and the sprue gate 1 is connected to the die cavity 9 by bilateral charging running channel；
The bilateral charging running channel includes: left shunt road 2, right runner 3, left feed channel 4 and right feed channel 5, the left side point
Runner 2 is connected with the left feed channel 4, and the right runner 3 is connected with the right feed channel 5, and the left shunt road 2 and institute
It states right runner 3 to intersect, which is connected to the sprue gate 1 and realizes bilateral charging casting.
It further illustrates, the left feed channel 4 is made of several left branch flow passages 6 being parallel to each other, each left branch flow passage 6
It is connected to on the left of the die cavity 9, second diffluence is carried out by each left feed channel 4 of 6 pairs of left branch flow passage again, while to being poured in die cavity 9
Melt is infused, poring rate is further speeded up, in addition, can make by each left branch flow passage 6 while to being poured on the left of die cavity 9
Obtain 9 left side of die cavity can be carried out feeding everywhere, further increase total quality.
It further illustrates, the right feed channel 5 is made of several right branch flow passages 7 being parallel to each other, each right branch flow passage 7
It is connected to on the right side of the die cavity 9, second diffluence is carried out by each right feed channel 5 of 7 pairs of right branch flow passage again, while to being poured in die cavity 9
Melt is infused, poring rate is further speeded up, in addition, can make by each right branch flow passage 7 while to being poured on the right side of die cavity 9
