Description
Technical field
The utility model relates to casting processing technique field, specifically refers to a kind of Platen in Injection Molding Machine casting pouring structure.
Background technology
Platen in Injection Molding Machine is parts important in two-plate injection machine, two-plate injection machine eliminates the tailgate in mold closing mechanism, clamp force is acted directly in two pieces of templates of fixed mould, equipment can be saved lot of materials and take up an area space thus, and there is the advantage that cost is low, equipment formed precision is high, but the clamp force of two-plate injection machine only acts between a plate, two plates, support then not holding capacity, therefore the casting technique of correct plate requires very high.
The existing cast structure to Platen in Injection Molding Machine foundry goods as shown in Figure 1, it comprises sprue a, what be connected to sprue lower end breeds groove b, be connected to two cross gate c breeding groove b two ends and be connected to below cross gate c and towards some ingate d of die cavity, existing cast structure comes with some shortcomings part: 1, iron liquid is through sprue, breed groove and cross gate when entering into ingate, because ingate does not arrange reducing-flow structure, thus be easy to cause iron flow velocity too fast, and then iron liquid can be made to occur turbulent flow, eddy current, the phenomenons such as secondary oxidation, on filling type stability and casting quality causes impact, 2, ingate is connected directly between the below of cross gate, and when cross gate is not full of by iron liquid, iron liquid enters die cavity by ingate, and the air in cross gate cannot be discharged completely, and iron liquid is easy to be oxidized further because of ingress of air, finally affects casting quality, 3, existing cast structure ingate is too much, and cross gate is provided with two, not only increases casting cost, and simultaneously because ingate is spliced by more piece porcelain tube, ingate too much adds the labour intensity of staff.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of type that fills to stablize, iron liquid can be avoided to occur the phenomenons such as turbulent flow, eddy current, secondary oxidation, can reduce the Platen in Injection Molding Machine casting pouring structure of production cost and intensity of workers.
For solving the problems of the technologies described above, the utility model provides a kind of Platen in Injection Molding Machine casting pouring structure of following structure, comprise the sprue for entering iron liquid, vertical with sprue and be communicated with breed groove, with breed the cross gate and the some ingates be communicated with cross gate that groove is communicated with, described cross gate and breed between groove and be provided with filter block, described ingate is provided with the structure for slowing down iron flow velocity.
Platen in Injection Molding Machine casting pouring structure of the present utility model, wherein, on described ingate, the structure be provided with for slowing down iron flow velocity refers to, the horizontal sides of described ingate is provided with reducer, is extended to the original internal diameter of ingate more gradually after the internal diameter of described reducer shrinks gradually.
Platen in Injection Molding Machine casting pouring structure of the present utility model, wherein, described cross gate to be all communicated with ingate with cross gate and the ingate with cavity overlaps block with being provided with between ingate.
Platen in Injection Molding Machine casting pouring structure of the present utility model, wherein, bottom described ingate overlap joint block, side is communicated with the upper surface of cross gate, and it is vertical and be communicated with that vertical long limit and the ingate of described ingate overlap the lower surface of block.
Platen in Injection Molding Machine casting pouring structure of the present utility model, wherein, the quantity of described cross gate is one.
Platen in Injection Molding Machine casting pouring structure of the present utility model, wherein, described in breed the side that groove, cross gate and some ingates are all positioned at sprue.
After adopting said structure, compared with prior art, the utility model has the following advantages: 1, by being provided with the structure for slowing down iron flow velocity on ingate, the horizontal sides of i.e. ingate is provided with reducer, when iron liquid is through sprue, breed groove and cross gate when entering into ingate, due to the internal diameter of reducer shrink gradually after be extended to the original internal diameter of ingate more gradually, therefore when iron liquid enters reducer leading portion, the internal diameter of reducer leading portion shrinks gradually, the flow of iron liquid can reduce, when iron liquid enters into reducer back segment from reducer leading portion, the internal diameter of reducer back segment expands gradually, the flow of iron liquid is made to keep inconvenient and flow velocity reduction, thus avoid iron liquid to occur turbulent flow, eddy current, the phenomenon of secondary oxidation, ensure that and fill the stability of type and the quality of foundry goods, 2, by arranging ingate overlap joint block between cross gate and ingate, and side is communicated with the upper surface of cross gate bottom ingate overlap joint block, the vertical long limit of ingate and ingate overlap the lower surface vertical connection of block, when iron liquid enters into cross gate, iron liquid goes up gradually from cross gate inner bottom part and is full of whole cross gate, thus the air in cross gate can be discharged completely, avoid the secondary oxidation of iron liquid, ensure that the quality of foundry goods, 3, cross gate is reduced to one from two, and ingate is corresponding minimizing also, not only reduces casting cost, also reduces the labour intensity of staff simultaneously.
