The utility model content
The purpose of the utility model is to the problems referred to above weak point a kind of deslagging sprue bush that is used for aluminium alloy extruded mould to be provided, and it can effectively intercept the aluminium slag and oxide inclusion enters into die cavity, guarantees casting quality.
In order to achieve the above object, the utility model adopts following technical scheme:
A kind of deslagging sprue bush that is used for aluminium alloy extruded mould comprises the sprue bush body, and the interior bottom of said sprue bush body is provided with the material chamber with binder tube uniform internal diameter, and the top in said material chamber is awl neck chamber, and this awl neck chamber is provided with the annular groove group.
As preferably, be provided with material chamber shoulder between said material chamber and the awl neck chamber.
Further preferred, the shoulder structure of above-mentioned material chamber shoulder for upwards arching upward.
As preferably, the step shape groove structure of said annular groove group for from bottom to top successively decreasing successively.
As preferably, the periphery wall of the corresponding material of said sprue bush body position, chamber is provided with cooling structure; This cooling structure comprises the cooling annular groove of being located at the corresponding material of sprue bush body position, chamber periphery wall and the cooling ring set of being located at this cooling annular groove outside.
Further, said sprue bush body lower edge is provided with the binder jacket casing cooperates and is connected seam.
The utility model novelty sprue bush is carried out structure of modification,, can effectively intercept the aluminium slag and oxide inclusion enters into die cavity, guarantee casting quality through the annular groove group being set on the awl neck chamber and expecting the chamber shoulder being provided with between material chamber and the awl neck chamber.

Come the utility model is further described below in conjunction with the accompanying drawing and the specific embodiment.
The specific embodiment
Shown in Fig. 1 to 3; The described a kind of deslagging sprue bush that is used for aluminium alloy extruded mould of the utility model comprises sprue bush body 1, and it is installed in the cover half of mould 2 and with die cavity 3 and is communicated with; Its underpart connects the binder tube 4 of vertical extrusion equipment; The utility model is guaranteed casting quality through effectively intercepting the aluminium slag to the sprue bush structure of modification and oxide inclusion 5 enters into die cavity 3, and its concrete structure is following:
Said sprue bush body 1 interior bottom is provided with the material chamber 11 with binder tube 4 uniform internal diameters; The top in said material chamber is awl neck chamber 12, and this awl neck chamber is provided with annular groove group 13, further; The step shape groove structure of said annular groove group 13 for from bottom to top successively decreasing successively, as shown in Figure 1.
In order further to improve the ability that obstruct aluminium slag and oxide inclusion thereof enter into die cavity 3, be provided with material chamber shoulder 14 between said material chamber 11 and the awl neck chamber 12.The shoulder structure of above-mentioned material chamber shoulder 14 for upwards arching upward.
In order to increase cooling effect, the periphery wall of said sprue bush body 1 corresponding material 11 positions, chamber is provided with cooling structure 15; This cooling structure comprises the cooling annular groove 151 of being located at sprue bush body 1 corresponding material chamber 11 position periphery walls and the cooling ring set 152 of being located at this cooling annular groove outside.
Further, said sprue bush body 1 lower edge is provided with binder tube 4 cover cooperates and is connected seam 16.
Below come the utility model is further described through accompanying drawing and concrete application principle:
The utility model utilizes the flow behavior of fluid to combine the operation principle of vertical extruding that sprue bush is carried out structure of modification; To realize effectively intercepting the purpose that aluminium slag and oxide inclusion 5 thereof enter into die cavity 3; As shown in Figure 2; When molten aluminium alloy 6 made progress flow process in binder tube 4 in, the difference of resistance was the intermediate projections shape owing to molten aluminium alloy 6 receives radially in the binder tube, and the aluminium slag or the oxide inclusion that are present in front end also distribute to barrel thereupon; Rise when arriving material chamber shoulders and awl neck chamber when molten aluminium alloy 6 is mild, the annular groove group at shoulder structure that aluminium slag and oxide inclusion are upwards arched upward (maybe can be called the big annular groove that upwards arches upward) and place, awl neck chamber intercepts and stops and along with molten aluminium alloy 6 flows and is adjacent to material chamber shoulder 14 and annular groove group 13 (or the approximate shape of wriggling).As shown in Figure 3; In extrusion process, fill type early stage molten aluminium alloy 6 flowing phases to gently, the aluminium slag is close to material chamber shoulder 14 and annular groove group 13 with oxide inclusion 5; Add the cooling effect of cooling annular groove 151 in addition; The molten aluminium alloy 6 that contact annular groove group 13 surface at first have relative Quench reaction and are tending towards solidifying, and the later stage is brought in the molten aluminium alloy 6 because of the effect of washing away with oxide inclusion 5 although have the small amount of aluminum slag when pushing fast; But because of running channel also accounts for the suitable volume fraction of foundry goods, aluminium slag and oxide inclusion finally also can only be brought to runner.So just intercept aluminium slag and oxide inclusion effectively, guaranteed the quality of foundry goods.
The utility model novelty sprue bush is carried out structure of modification, through the annular groove group being set on the awl neck chamber and between material chamber and the awl neck chamber material chamber shoulder being set, the ability available energy effectively intercepts the aluminium slag and oxide inclusion enters into die cavity, guarantees casting quality.
