Abstract
The utility model relates to a pouring device, in particular to an improved hub runner, which enables the percentage of pass of poured hubs to be high and enables scrap removal to be simple. The improved hub runner is characterized by comprising a sprue, two runners and two ingates. The sprue is perpendicular to the runners, outlets of the sprue are communicated with the runners, inlets of the two runners are communicated with different outlets of the sprue, the two runners are communicated with the two ingates simultaneously, and liquid outlets of the two ingates are communicated with the inner wall of a hub casting.
Description
Technical field
The utility model relates to a kind of apparatus for pouring, refers in particular to a kind of follow-on wheel hub running channel.
Background technology
The design of existing mould is general adopts single runner system design, is illustrated in figure 1 as existing wheel hub list running channel, and mould is designed with sprue 1 ＇ and cross gate 2 ＇ and ingate 3 ＇ when design.When die cast, have only one molten metal bath to be cast to wheel hub 4 ＇ model cavities.This mould structure simplicity of design; Mould Machining is relatively easy, but the aluminium liquid that flow in the unit interval in the mold cavity is few, and it is long that promptly aluminium liquid is full of the required time of die cavity; It is more to cause in the filling process of aluminium liquid in mold cavity temperature to descend; Arrived last filling position, piece surface be prone to produce owes casting, cold shut, casting flaw such as loose, influences the qualification rate of product.So, use this die production, the qualification rate of wheel hub 4 ＇ can only reach 91%.In addition, this structure is gone the stub bar complex process, can't directly knock out, and must use milling machine, influences efficient and increases cost.
To the problems referred to above, the utility model inventor has proposed a kind of modified wheel hub running channel, has overcome above-mentioned defective well.
The utility model content
The utility model is to the disappearance of prior art existence, and it is high that its main purpose provides a kind of casting wheel hub qualification rate, removes the simple modified wheel hub of stub bar running channel.
For realizing above-mentioned purpose, the utility model adopts following technical scheme: a kind of modified wheel hub running channel, comprise sprue, cross gate and ingate, and said sprue is connected with cross gate perpendicular to cross gate and outlet; Said cross gate has two, and the difference outlet of import connection sprue separately, and these two cross gates are connected with two different ingates respectively simultaneously; Said ingate is two, and its liquid outlet is communicated with the inwall of wheel hub casts.
After the utility model adopted technique scheme, its beneficial effect was: the design of double teeming road system, i.e. two cross gates of mould design and ingate are adopted in the mould design.Promptly pass through cae analysis; After the forming process of liquid towards metal in mold cavity had sufficient grasp; Again according to the characteristics of wheel hub structure; Mould is optimized design, promptly on mould, chooses two two cross gates of optimum position design and ingate, when die cast, have two strands of molten aluminum liquids to be injected to the compression mod die cavity.In addition,, promptly rationally confirm injection power, injection speed, dwell time etc., thereby also guaranteed the smooth moulding of product on the technology through improvement to extrusion process.Therefore through improvement to mould structure; Make wheel hub in forming process; Flow into the interior aluminium liquid phase of mold cavity in unit interval to increasing; Be that aluminium liquid is full of the required time of die cavity and shortens 50% with respect to (single running channel) before improving, make that temperature descends seldom in the filling process of aluminium liquid in mold cavity, the temperature that has arrived last filling position changes little with respect to the position of filling at first; Overcome because of last temperature of filling the position reduce cause owe casting, cold shut, die casting defective such as loose, the qualification rate of wheel hub is reached more than 99%.In addition, this structure goes stub bar technology simple, can directly knock out, and need not use milling machine, has improved efficient and has reduced cost.

The specific embodiment:
Come the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment: a kind of modified wheel hub running channel that is illustrated in figure 2 as the utility model; Comprise sprue 1, cross gate 2 and ingate 3, said sprue 1 is connected with cross gate 2 perpendicular to cross gate 2 and outlet; Said cross gate 2 has two, and the difference outlet of import connection sprue 1 separately, and these two cross gates 2 are connected with two different ingates 3 respectively simultaneously; Said ingate 3 is two, and its liquid outlet is communicated with the inwall of wheel hub 4 foundry goods.
Focusing on of the utility model, mould design are adopted the design of double teeming road system, i.e. mould design two cross gates 2 and ingate 3.Promptly pass through cae analysis; After the forming process of liquid towards metal in mold cavity had sufficient grasp; Again according to the characteristics of wheel hub 4 structures; Mould is optimized design, promptly on mould, chooses two optimum position design two cross gates 2 and ingate 3, when die cast, have two strands of molten aluminum liquids to be injected to the compression mod die cavity.In addition,, promptly rationally confirm injection power, injection speed, dwell time etc., thereby also guaranteed the smooth moulding of product on the technology through improvement to extrusion process.Therefore through improvement to mould structure; Make wheel hub 4 in forming process; Flow into the interior aluminium liquid phase of mold cavity in unit interval to increasing; Be that aluminium liquid is full of the required time of die cavity and shortens 50% with respect to (single running channel) before improving, make that temperature descends seldom in the filling process of aluminium liquid in mold cavity, the temperature that has arrived last filling position changes little with respect to the position of filling at first; Overcome because of last temperature of filling the position reduce cause owe casting, cold shut, die casting defective such as loose, the qualification rate of wheel hub 4 is reached more than 99%.In addition, this structure goes stub bar technology simple, can directly knock out, and need not use milling machine, has improved efficient and has reduced cost.
The above; It only is the preferred embodiment of the utility model; Be not that the technical scope of the utility model is done any restriction; So every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any trickle modification, equivalent variations and modification that above embodiment did.
