Lower coagulation forming is to obtain the process of blank or part.In general, the running channel of vertical extrusion casting is cylinder, liquid gold
Belong to from bottom to top slowly, Stable Filling is, which means that molten aluminum is in such a way that ingate enters type chamber in vertical extrusion casting
Fixed, no image of Buddha horizontal type extruding casting controls molten aluminum flow direction by changing running channel and ingate shape and size like that subtract
Few defect can only improve product quality by adjusting extrusion casint parameter, such as poring rate, pressure, temperature parameter.Some
For part by structure and influence of wall thickness, there is speed and direction inconsistent situation during packed type chamber in metal liquid stream, low
Blocking of the fast liquid stream by high speed liquid flow, looping, the filling of low speed liquid stream are obstructed, and often will cause the cold shut defect of product.Cold shut lacks
Falling into is metal liquid stream meet in finger-type chamber, and metal liquid stream merges the not perfect gap for causing casting generation to penetrate or do not penetrate.
Cold shut defect has development trend under external force, be easy to cause crackle, reduces casting strength.Eliminating this defect must pass through
The rational design of mold.

It is further used as the improvement of technical solutions of the utility model, big wall thickness is reinforcing rib.
It is further used as the improvement of technical solutions of the utility model, the cross sectional shape of turbulator rod is circle, triangle, ladder
Shape, square in any one.
The utility model has the beneficial effects that this is used for the turbulence structure of vertical extrusion casting mold, liquid metal is along running channel
It fills from the bottom up, the top of running channel is ingate, and liquid metal enters type chamber and filled-type chamber through ingate, and turbulator rod is set to
The front of the faster part of filling speed, hinders the entrance of liquid metal, to slow down filling speed, makes itself and other parts
Filling speed is similar, guarantees that filling speed is uniform, prevents cold shut defect.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing:
Fig. 1 is the front view of the utility model embodiment；
Fig. 2 is the structural schematic diagram of the utility model embodiment casting；
Fig. 3 is the top view of the utility model embodiment.
Specific embodiment
Referring to Fig.1~Fig. 3, the utility model are a kind of turbulence structure for vertical extrusion casting mold, including upper mold 1
With lower die 2, lower die 2 is equipped with running channel 21, and upper mold 1 is equipped with turbulator rod 3 in the top position of running channel 21.
This is used for the turbulence structure of vertical extrusion casting mold, and liquid metal is filled from the bottom up along running channel 21, running channel 21
Top be ingate, liquid metal enters type chamber 4 and filled-type chamber 4 through ingate, and it is faster that turbulator rod 3 is set to filling speed
Partial front, hinders the entrance of liquid metal, to slow down filling speed, makes its filling speed difference with other parts not
It is more, guarantee that filling speed is uniform, prevents cold shut defect.
This turbulence structure is located at the mold in 5 middle position of casting mainly for vertical extrusion casting mold, ingate.
As the utility model preferred embodiment, shape forming cavity 4, liquid metal is cast between upper mold 1 and lower die 2
Casting 5 is formed to type chamber 4, casting 5 is equipped at least two big wall thickness 51, is equipped with small wall thickness between adjacent two big wall thickness 51
Portion 52, the wall thickness at big wall thickness 51 are greater than the wall thickness at small wall thickness 52, the quantity of the quantity of turbulator rod 3 and big wall thickness 51
Equal, each turbulator rod 3 is located at the front of major wall thickness 51.In general, the rib thickness general goal in casting 5 is big wall thickness
51, in traditional extrusion casint, since the wall thickness at big wall thickness 51 is larger, the resistance that liquid metal enters at this is small, liquid
State metal preferentially flows into the position of big wall thickness 51, is then refluxed for, and is formed and is converged at small wall thickness 52, hinders subsequent liquid
The filling of metal, gas can not be discharged, and in the junction of liquid metal, fusion is poor, to form cold shut defect.And it increases
