Description
Technical field
The utility model relates to a kind of case lid casting dies.
Background technique
The shell of large-scale engineering machinery needs that case lid is cooperated to come using shell and case lid are required to bear in use
Very high stress, therefore requirement when using pouring type production case lid, to the appearance and internal soundness of case lid casting
Very high, any manufacturing deficiency is likely to scrap it, influences the yield rate of case lid.
In the prior art, large-sized casting can exist in casting process and be easy to make because potting syrup stroke is too long
The defects of at pouring less than, cold shut；Meanwhile structure is complicated for case lid casting, thickness is different, and casting section thickness unevenly not only easily produces
The defects of raw shrinkage cavity and porosity, it also will increase each section temperature difference, to generate casting stress, or even cause to crack.Secondly, finished product
Acceptance requirement is also very high, needs to carry out non-destructive testing entire product, therefore the design of case lid casting and running gate system is wanted
Ask also very high.To sum up, it when case lid casting is cast, needs to design different pour according to the case lid of different shape and structure
There is the yield and quality of casting and adversely affect in injection system if Design of Runner System is improper.
Summary of the invention
The shortcomings that the purpose of this utility model is to overcome the prior arts provides a kind of case lid casting die, according to
The shape of case lid designs reasonable running gate system, improves the casting quality of case lid.
In order to achieve the above objectives, the technical solution adopted in the utility model is: a kind of case lid casting die, including shell
Lid casting, running gate system, the case lid casting include that caping, one end are connected with the caping and circumferentially set along the caping
The side wall set, the lid end for being connected to the side wall other end, the side wall are gradually inclined outwardly from the caping to lid end,
The side wall is equipped with through-hole；The running gate system include sprue cup, the sprue being connected with the sprue cup, with it is described straight
The ingate of cross gate, the connection cross gate and case lid casting that running channel is connected is emitted with what the cross gate was connected
Mouthful；The cross gate includes that the first cross gate being connected with the sprue, two one end are connected with first cross gate
The second logical cross gate, the ingate are connected with second cross gate and case lid casting.
Preferably, it is connected in the middle part of the sprue and first cross gate.
Preferably, second cross gate is set to the top of first cross gate.
Preferably, two second cross gates are symmetrically disposed in the both ends of first cross gate.
Preferably, the other end of second cross gate is connected with the ingate.
Preferably, the riser is set to the connectivity part of second cross gate and the ingate.
Preferably, the ingate is connected with the lid end.
Preferably, have on the lid end to the holding section protruded far from the caping direction.
Preferably, in a ring, the case lid casting is arranged in the running gate system to the side wall of the case lid casting
Side.
Since above-mentioned technical proposal is used, the utility model has the advantage that the utility model compared with prior art
A kind of case lid casting die, reasonable running gate system is designed according to the shape of case lid, enables potting syrup steadily quickly
Ground flowing, reduces the temperature difference of each part of casting, prevents casting local deformation, cracking, shrinkage cavity and porosity and potting syrup stroke is too long makes
At cold shut, misrun the defects of, the qualification rate of case lid casting can be greatlyd improve.
