Connect, the duct, first core pulling and second core pulling are collectively forming stern rudder shape chamber, and the periphery of first core pulling is set
It is equipped with loose plug, the duct is connected with annular channel, and one end of the annular channel is from the front cavity or described
The side of rear cavity is stretched out, and the side of the rear cavity and the front cavity is provided with the first take-up housing, the front cavity and institute
The opposite side for stating rear cavity is provided with the second take-up housing, and the side of first core pulling is additionally provided with oblique top and thimble.
One kind as stern rudder die casting of the present invention is improved, and the side of the annular channel is connected with charging basket.
One kind as stern rudder die casting of the present invention is improved, and the duct is connected with first exhaust by exhaust passage
Valve.
One kind as stern rudder die casting of the present invention is improved, and the first row air valve is arranged to three.
One kind as stern rudder die casting of the present invention is improved, and waste material bag is provided with the exhaust passage.
One kind as stern rudder die casting of the present invention is improved, and the duct is also connected with second row by exhaust passage
Air valve.
One kind as stern rudder die casting of the present invention is improved, the first row air valve and second row air valve difference
It is arranged at the both sides of the front cavity or is arranged at the both sides of the rear cavity.
Relative to prior art, the present invention passes through sets loose plug in the periphery of the first core pulling so that mould can one
Secondary shaping, solve the problems, such as that side opening core pulling can not also need to process using post-processing during depanning well, simplify process,
Save production cost.And the present invention can cause annular products to fill fuller by using the mode of side annular charging
Completely, so as to efficiently solve product sand hole and air-tightness the problem of, while make it that the outward appearance of product is more beautiful.

Embodiment
The present invention and its advantage are further described with reference to specification drawings and specific embodiments, but
It is that embodiment of the invention is not limited to this.
As illustrated in fig. 1 and 2, a kind of stern rudder die casting provided by the invention, including front template 1, rear pattern plate 2, preceding mould
Benevolence 3 and the rear cavity 4 matched with front cavity 3, front cavity 3 are arranged in front template 1, and rear cavity 4 is arranged in rear pattern plate 2, preceding
The first core pulling 5 and the second core pulling 6 are provided between die 3 and rear cavity 4, passes through duct between the first core pulling 5 and the second core pulling 6
7 connections, duct 7, the first core pulling 5 and the second core pulling 6 are collectively forming stern rudder shape chamber（The stern rudder shape chamber is located at the He of front cavity 3
Between rear cavity 4）, the periphery of the first core pulling 5 is provided with loose plug 8, and duct 7 is connected with annular channel 9, and annular channel
9 one end is stretched out from the side of front cavity 3 or rear cavity 4（So that the mode that the present invention is fed is side annular charging）, rear mold
The side of benevolence 4 and front cavity 3（That is the same side of rear cavity 4 and front cavity 3）The first take-up housing 10 is provided with, front cavity 3 is with after
The opposite side of die 4 is provided with the second take-up housing 11, and the side of the first core pulling 5 is additionally provided with oblique top 12 and thimble 18.
The side of annular channel 9 is connected with charging basket 13, and for supplying feed liquid, feed liquid enters annular channel 9 from charging basket 13
After be filled with stern rudder shape chamber.Feed liquid is generally aluminium fused solution.
Duct 7 is connected with first row air valve 15 by exhaust passage 14, for discharging the air in stern rudder shape chamber.First
Air bleeding valve 15 is arranged to three, is easy to fast and effeciently discharge the air in stern rudder shape chamber.
Waste material bag 16 is provided with exhaust passage 14, the effect of waste material bag 16 is ship under the injection pressure of die casting machine
Then the cold burden ejectment of tail vane shape intracavitary is discharged air by first row air valve 15, so as to improve product in waste material bag 16
Quality.
Duct 7 is also connected with second row air valve 17 by exhaust passage 14, and first row air valve 15 and second row air valve 17 divide
The both sides of front cavity 3 are not arranged at or are arranged at the both sides of rear cavity 4, so as to from different directions by the air in stern rudder shape chamber
Discharge.
In use, first opening front template 1, then the first core pulling 5 is inserted, then loose plug 8 is fixed on the first core pulling 5
Side, the second core pulling 6, then locked loose plug 8 are inserted into, to prevent loose plug 8 from shifting；Then the He of front template 1
On rear pattern plate is 2-in-1, die casting machine nozzle alignment charging basket 13 is fed, feed liquid by annular channel 9 be filled with front cavity 3 and rear cavity 4 it
Between stern rudder shape intracavitary.After completing die casting, front template 1 is opened, the first core pulling 5 and the second core pulling 6 are exited, loose plug 8
Then stay on product, oblique top 12 and thimble 18 eject product, complete formed product.It is artificial to take out loose plug 8 after ejection,
Production is completed, the structure of obtained stern rudder product is as shown in Figures 3 and 4.
In a word, in the prior art, die side hole forming is usually and completed by slipper block loose core, can not depanning in some core pullings
In the case of, it is necessary to by the way of post-processing, and the present invention dexterously sets loose plug 8 in the periphery of the first core pulling 5, makes
Mould can one-shot forming, simplify process, save production cost.
What the feeding manner of die casting was typically chosen in the prior art be plane charging, but this feeding manner for
For the special product of this structure of stern rudder and do not apply to, the present invention can cause by using the mode of side annular charging
Annular products are filled fuller, the problem of so as to efficiently solve product sand hole and air-tightness, while cause the outer of product
See more beautiful.
In addition, it is of the invention by the distribution of the position and exhaust passage 14 that are reasonably laid out waste material bag 16, being capable of maximum journey
Degree ground reduces the generation of bad products, and improves the finish of product surface.
It should be noted that the announcement and elaboration of book, those skilled in the art in the invention may be used also according to the above description
So that above-mentioned embodiment is changed and changed.Therefore, the invention is not limited in specific implementation disclosed and described above
Mode, some equivalent modifications and change to the present invention should also be as in the scope of the claims of the present invention.In addition, to the greatest extent
