Description
Technical field
This utility model relates to a kind of cast-aluminum die, especially relates to a kind of casting aluminum rotor mould based on tangential runner.
Background technology
Current commonly used vertical pressure aluminium casting machine carries out the cast aluminium of rotor.Being promoted the piston of die casting machine that the liquid aluminium melted is pressed into the casting runner hole of cast-aluminum die by hydraulic system, push the grooved intracavity after laminating into rotor punching, after pressurize, cooling, die sinking, the cast-aluminum rotor of a motor is the formation of.During whole cast aluminium, the change of aluminum process parameter includes the improper product that all can make last die cast that selects of cast-aluminum die runner, and the most that more elongated slot shape of rotor produces wraps up in the defect such as gas, cold shut.
It is illustrated in figure 1 the structural representation of conventional rotors cast-aluminum die, an annular end ring forming chamber 5 is had on die ontology 1, runner hole 4 it is evenly distributed with in end ring forming cavity 5, runner hole 4 uses straight channel, rotor punching 2 is placed on above die ontology 1, and rotor slot die cavity 3 position on rotor punching 2 is corresponding with the position in runner hole 4, but runner hole 4 quantity is not the quantity one_to_one corresponding with rotor slot die cavity 3.nullOwing to runner hole 4 all uses straight channel，And quantitative relation can not be with rotor slot die cavity 3 one_to_one corresponding，During so liquid aluminium injects die ontology 1 by the runner hole 4 on end ring forming cavity 5 during cast aluminium，The liquid aluminium liquid level rate of climb in each rotor slot die cavity 3 is different，As now runner hole 4 is not aligned with grooved chamber 3，In runner hole 4, the aluminum liquid of injection is turned back after encountering rotor punching 2，The speed that in certain the grooved chamber 3 closed on this point, aluminum liquid rises can slow down，And if runner hole 4 is just directed at grooved chamber 3，Its aluminum liquid will directly pass through grooved chamber 3 directive upper mold，To turn back backflow from adjacent slot die cavity 3 after encountering upper mold，And at a time converge with the aluminum liquid that rising in this grooved chamber 3，Cast aluminium in grooved chamber 3 easily produces and wraps up in gas and cold shut in the process，Cause the hydraulic performance decline of rotor.
Utility model content
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and a kind of casting aluminum rotor mould based on tangential runner is provided.
The purpose of this utility model can be achieved through the following technical solutions:
nullA kind of casting aluminum rotor mould based on tangential runner，Including die ontology，Described die ontology is annular box like structure，Described die ontology central authorities are provided with the column column of fixed rotor punching，Described uprights vertical is in die ontology bottom surface，Described die ontology also includes packing ring and runner ring，Described runner ring is arranged along die ontology inside edge，The outer ring surface of described runner ring is close to die ontology side，The inner ring surface of runner ring、Column and die ontology bottom surface form end ring forming cavity，Multiple runner hole it is uniformly distributed on described runner ring，It is correspondingly provided with, on described die ontology bottom surface, the through hole connected with runner hole，The inner ring surface edge of described runner ring has the runner tangent with runner hole，Each runner hole is correspondingly arranged a runner，Described runner all connects end ring forming cavity，Described packing ring is arranged on above runner ring and arranges along die ontology inside edge.
Described packing ring includes multiple arc cushion block, and described cushion block is spliced to form ring spacer successively.
Described packing ring internal ring radius is more than or equal to the internal ring radius of runner ring.
Angle between described runner axis and the tangent line of end ring forming cavity is 15 °～45 °.
Described runner ring is runner ring integrated with die ontology.
Described column is the column integrally formed with described die ontology.
Compared with prior art, this utility model has the advantage that
(1) this utility model is by runner ring, runner hole, runner and packing ring collaborative work, when the runner hole that aluminum liquid through hole from die ontology is corresponding is upwards sprayed, first packing ring stops the aluminum liquid upwards sprayed, aluminum liquid is forced to change flow direction, along the runner upstream end loop forming chamber tangent with runner hole, and then be full of under the effect of the pressure and by the grooved chamber on rotor punching, it is to avoid turn back due to aluminum liquid and produce wrap up in gas and cold shut, and then improve product quality；
(2) packing ring in this utility model uses multiple arc cushion blocks to be spliced, simple in construction, it is simple to install and dismantle；
(3) in this utility model, corner dimension between the tangent line of runner axis and end ring forming cavity is moderate, make aluminum liquid when being flowed in end ring forming cavity by runner hole, form one and rotate the liquid flow risen, be more beneficial for aluminum liquid and flow up the grooved chamber being uniformly filled in rotor punching；
(4) this utility model runner ring and column all use the structure integrally formed with die ontology, thus are simple to manufacture conveniently, it is simple to produce and promote.
Accompanying drawing explanation
Fig. 1 is the structural representation of conventional rotors cast-aluminum die；
Fig. 2 is the structural representation of this utility model casting aluminum rotor mould.
In figure, 1 is die ontology, and 2 is rotor punching, and 3 is rotor slot die cavity, and 4 is runner hole, and 5 is end ring forming cavity, and 6 is column, and 7 is runner ring, and 8 is runner, and 9 is cushion block.
Detailed description of the invention
With specific embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
Embodiment
As shown in Figure 2, a kind of casting aluminum rotor mould based on tangential runner, including die ontology 1, die ontology 1 is annular box like structure, die ontology 1 central authorities are provided with the column column 6 of fixed rotor punching, and column 6 is the column 6 integrally formed with die ontology 1, and column 6 is perpendicular to die ontology 1 bottom surface, the outer annular diameter of column 6 matches with the diameter of rotor punching upper rotor part axle, is enclosed within by rotor punching on this column 6 and can carry out the fixing of rotor punching.
nullDie ontology 1 also includes packing ring and runner ring 7，Runner ring 7 is arranged along die ontology 1 inside edge，The outer ring surface of runner ring 7 is close to die ontology 1 side，The inner ring surface of runner ring 7、Column 6 and die ontology 1 bottom surface form end ring forming cavity 5，Multiple runner hole 4 it is uniformly distributed on runner ring 7，Die ontology 1 is correspondingly provided with, on bottom surface, the through hole connected with runner hole 4，The inner ring surface edge of runner ring 7 has the runner 8 tangent with runner hole 4，Each runner hole 4 is correspondingly arranged a runner 8，Runner 8 all connects end ring forming cavity 5，Angle between the tangent line of runner 8 axis and end ring forming cavity 5 is 15 °～45 °，Here the θ angle that the angle between runner 8 axis and the tangent line of end ring forming cavity 5 is in figure，In the present embodiment, θ angle is set to 30 °，Packing ring is arranged on above runner ring 7 and arranges along die ontology 1 inside edge.Its middle washer includes multiple arc cushion block 9, and cushion block 9 is spliced to form ring spacer successively, and packing ring internal ring radius is more than or equal to the internal ring radius of runner ring 7 so that packing ring can effectively stop the aluminum liquid upwards sprayed in runner hole 4.The cushion block 9 that the present embodiment middle washer uses 3 block sizes consistent with shape is spliced, and shows the structure of runner ring 7 under cushion block 9 for convenience, the most only depict 2 pieces of cushion blocks 9 in Fig. 2.This utility model uses spliced cushion block 9 to form the mode of packing ring, simple in construction, it is simple to install and dismantle.Runner ring 7 is that through hole corresponding on runner ring 7 integrated with die ontology 1, therefore runner hole 4 and rotor punching is also for one-shot forming.
