Abstract
The invention belongs to the technical field of dies, and particularly relates to a stern rudder die-casting die. The stern rudder die-casting die comprises a front die plate, a rear die plate, a front die core and a rear die core matched with the front die core, wherein a front loose core and a second loose core are arranged between the front die core and the rear die core; the first loose core and the second loose core are connected through a pore passage; the pore passage, the first loose core and the second loose core form a stern rudder-shaped cavity together; movable inserts are arranged on the periphery of the first loose core; the pore passage is connected with annular flow passages, and one end of each of the annular flow passage stretches out from the side of the front die core or the rear front die; a pitched roof and a thimble are further arranged on one side of the first loose core. Compared with the prior art, the movable inserts are arranged on the periphery of the first loose core, so that the die can be formed once, the process is simplified, and the production cost is reduced. Moreover, annular products can be filled more fully in a side edge annular feeding manner, and thus the problems of product sand hole and air impermeability are effectively solved, and meanwhile the appearance of the product is more attractive.

Detailed description of the invention
Below in conjunction with specification drawings and specific embodiments, the present invention and beneficial effect thereof are further described, but the specific embodiment of the present invention is not limited to this.
As illustrated in fig. 1 and 2, a kind of stern rudder die casting provided by the invention, comprise front template 1, rear pattern plate 2, front cavity 3 and the rear cavity 4 of mating with front cavity 3, front cavity 3 is arranged in front template 1, rear cavity 4 is arranged in rear pattern plate 2, between front cavity 3 and rear cavity 4, being provided with first looses core and 5 and second looses core 6, first looses core 5 and second looses core and connects by duct 7 between 6, duct 7, the first 5 and second 6 common stern rudder shape chambeies (this stern rudder shape chamber is between front cavity 3 and rear cavity 4) that form of loosing core of loosing core, the first loose core periphery of 5 is provided with loose plug 8, duct 7 is connected with annular channel 9, and (mode that makes charging of the present invention is the charging of side annular) stretched out from the side of front cavity 3 or rear cavity 4 in one end of annular channel 9, one side (being the same side of rear cavity 4 and front cavity 3) of rear cavity 4 and front cavity 3 is provided with the first take-up housing 10, the opposite side of front cavity 3 and rear cavity 4 is provided with the second take-up housing 11, the first loose core side of 5 is also provided with oblique top 12 and thimble 18.
One side of annular channel 9 is connected with charging basket 13, and for supplying feed liquid, feed liquid is filled with stern rudder shape chamber from charging basket 13 enters into annular channel 9.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 row air valve 15 is set to three, is convenient to fast and effeciently by the Bas Discharged in stern rudder shape chamber.
In exhaust passage 14, be provided with waste material bag 16, the effect of waste material bag 16 is under the injection pressure of die casting machine, the cold burden ejectment in stern rudder shape chamber to be arrived in waste material bag 16, then passes through first row air valve 15 by Bas Discharged, thereby improves the quality of product.
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 are arranged at respectively the both sides of front cavity 3 or are arranged at the both sides of rear cavity 4, thereby from different directions by the Bas Discharged in stern rudder shape chamber.
When use, first open front template 1, then by first 5 insertions of loosing core, then loose plug 8 is fixed on to the first loose core side of 5, then insert second and loose core 6, more locked loose plug 8, to prevent that loose plug 8 is shifted; Then front template 1 and rear pattern plate 2 are closed, die casting machine nozzle is aimed at charging basket 13 chargings, and feed liquid is filled with in the stern rudder shape chamber between front cavity 3 and rear cavity 4 by annular channel 9.Complete after die casting, open front template 1, loose core and 5 and second loose core and 6 exit first, 8 of loose plugs are stayed on product, and oblique top 12 and thimble 18 eject product, complete formed product.After ejecting, manually take out loose plug 8, complete production, the structure of the stern rudder product obtaining as shown in Figures 3 and 4.
In a word, in prior art, die side hole forming is generally to be completed by slipper block loose core, loose core cannot depanning in the situation that at some, just need the mode of processing after adopting, and the present invention arranges loose plug 8 in the first loose core periphery of 5 dexterously, make the mould can one-shot forming, simplify operation, saved production cost.
In prior art, the general selection of the feeding manner of die casting is plane charging, but this feeding manner is for the special product of this structure of stern rudder and inapplicable, the present invention can make annular products fill fulllyer by the mode that adopts the charging of side annular, thereby effectively solve product sand hole and bubble-tight problem, made the outward appearance of product more beautiful simultaneously.
In addition, the present invention, by the reasonably position of layout waste material bag 16 and the distribution of exhaust passage 14, can farthest reduce the generation of bad product, and improves the fineness of product surface.
It should be noted that, the announcement of book and elaboration according to the above description, those skilled in the art in the invention can also change and revise above-mentioned embodiment.Therefore, the present invention is not limited to detailed description of the invention disclosed and described above, also should be in the protection domain of claim of the present invention to equivalent modifications more of the present invention and change.In addition,, although used some specific terms in this description, these terms just for convenience of description, do not form any restriction to the present invention.
