Summary of the invention
Goal of the invention of the present utility model is to provide that a kind of aluminium bell housing product yield is higher, qualification rate is higher, surface quality is better, running gate system is conveniently removed, without the aluminium bell housing low pressure metal mould of rising head.
Technical solution of the present utility model is: comprise external mold, the core be loaded in external mold, running gate system; External mold comprises bed die, side form, patrix for the formation of aluminium alloy bell housing outer wall shape; Running gate system comprises sprue, cross gate, the annular ingate that is connected with foundry goods die cavity; Described cross gate comprises lower cross gate and upper cross gate; The bottom of core is located at by lower cross gate, and sprue, upper cross gate, annular ingate are located on bed die, are provided with screen pack in sprue, and sprue to be connected with annular ingate through cross gate and to form aluminium liquid pouring channel; Patrix being equipped with air exhaust rod, for ensureing that core is vented smoothly, patrix being also equipped with the insert coordinated with it.
Described sprue is positioned in the middle part of bed die, and sprue end is provided with running channel nest, and one section of lower cross gate is respectively established in sprue both sides, and sprue is connected with the middle part of lower cross gate; Upper cross gate one end is connected with lower cross gate one end respectively, and the upper cross gate other end is connected with annular ingate.
Described cross gate is fusiformis, and middle wide, two ends are narrow; Described lower cross gate and upper cross gate are parallel to each other.
Described upper cross gate adopts bridging type to be connected with lower cross gate, and the lap of splice is 60-80mm.
Place plane 8-10mm bottom annular ingate is exceeded bottom described upper cross gate.
Have step installing hole in the middle part of described patrix, comprise large stage portion, small stair portion, insert is flush-mounted in large stage portion, has the through hole corresponding with small stair portion in the middle part of insert.
The through-hole mounting of described air exhaust rod in insert is in small stair portion.
Described air exhaust rod is stepped cylinder, and comprise small column portion, big column portion, small column portion is plugged in small stair portion, and big column portion is stuck in insert.
Described side form is made up of more than two side form blocks.
Described side form is provided with air cooling system, is provided with air cooling system in insert.
This Design of Dies entirety meets the consecutive solidification of the step temperature field from low mould to patrix, and the gas that the gas of mold cavity and core produce can both smooth in exhaust.It is effective that the utility model keeps away slag, can not produce aluminium liquid emptying phenomenon, better can ensure product quality, improves product percent of pass.The very convenient removal of this running gate system.After this running gate system is arranged, other position does not need to arrange any rising head and carrys out feeding foundry goods, and larger improves product yield.

Detailed description of the invention
In Fig. 1,2,3, the utility model comprises the metal type dies surrounded by patrix 10, side form block 1, side form block 2 12, side form block 3 13, side form block 4 14 and bed die 9, and is arranged in the local inner chamber core 8 of described metal pattern die die cavity.The bottom of bed die 9 is provided with sprue (cast gate) 1 and annular ingate 6, upper cross gate 5.The bottom of core 8 is provided with lower cross gate 4.Side form block 1, side form block 2 12, side form block 3 13, side form block 4 14 form aluminium alloy bell housing peripheral shape, are provided with air cooling system (air blowing cooling system) being formed to hang to the side form block 2 12 of face shape and side form block 4 14.The gear chamber cavity shape of patrix adopts overall conformal insert 15 form to coordinate, and ensure that model cavity smooth in exhaust preferably.The center hole shape place of insert 15 is provided with comparatively large through-hole, and through hole is furnished with air exhaust rod 16, and be provided with passage in the middle of air exhaust rod 16, ensure that the gas that core produces is discharged smoothly preferably, air exhaust rod is the step cylinder of Intermediate Gray through hole.Cross gate is divided into two-layer up and down, namely descends cross gate 4, upper cross gate 5, is formed by connecting by bridging type form, whole cross gate direction according to hang to direction, position, place, face arrange, cross gate from centre bore to hanging to direction, face by diminishing gradually greatly, in contraction-like.Lower cross gate 4 is fusiformis, and middle wide, two ends are narrow.Upper cross gate 5 is trapezoidal, and going to the bottom of upper cross gate 5 is connected with lower cross gate 4, and the upper base of upper cross gate 5 is connected with annular ingate 6.The benefit of fusiformis is from sprue to ring running channel from large to small, is beneficial to aluminium liquid feeding order.Lower cross gate 4 is that bell housing center is to hanging to direction, face with upper cross gate 5 direction.After being arranged by the running channel in the utility model, without the need to increasing the feeding head of other form any.Lower cross gate 4 is connected with circular sprue 1, and screen pack 2 is placed in joint.Upper cross gate 5 and annular ingate 6 take comparatively orthodrome transition to be connected, and exceed 8-10mm bottom annular ingate 6 bottom upper cross gate 5.Annular ingate 6 is connected with foundry goods cavity.
Excise from ingate 6 and aluminium bell housing foundry goods 7 intersection, whole running gate system can be removed, very convenient.Aluminium liquid effectively can keep away slag by screen pack 2 and lower cross gate 4.
During assembling, by conformal insert 15, air exhaust rod 16 is fixed by screws on patrix 10.Before cast, inner chamber core 8 is placed on bed die 9, closes side form block 1, side form block 2 12, side form block 3 13, side form block 4 14, then the mould 10 that closes.During cast, aluminium liquid enters lower cross gate 4 from sprue 1 through screen pack 2, enters upper cross gate 5, then enters ingate 6, form aluminium bell housing foundry goods 7 by ingate 6 from lower cross gate 4.
