Description
Technical field:
The utility model relates to die casting manufacturing equipment technical field, specifically a kind of easy and simple to handle, air-tightness good, can significantly improve the die casting with high-air-tightness of casting quality.
Background technology:
Die casting is the technology that metal forming field is commonly used, and it is by liquid metal being filled mold cavity with high speed, obtaining the method for foundry goods under the effect of the pressure after cooled and solidified.Because metallic solution is filled into die cavity with the state of high velocity jet, in die cavity, original air has little time to discharge, and is inevitably trapped in inside workpiece, causes foundry goods to there is pore, have impact on the quality of foundry goods.
In order to solve the problem, existing die casting often supporting relevant vaccum-pumping equipment operates, before reality casting, first by the air in vaccum-pumping equipment emptying die cavity, reach the effect reducing the workpiece porosity, but limited efficiency, still cannot meet the processing request of high-fineness workpiece.
In addition, after liquid metal cools in a mold, need to be taken out by demoulding process, existing demoulding treatment process is simple, weak effect, can not complete the moulding of workpiece in die casting, gives to manufacture processing and bring difficulty.
Summary of the invention:
The utility model for the shortcoming and defect existed in prior art, propose a kind of easy and simple to handle, air-tightness good, can significantly improve the die casting with high-air-tightness of casting quality.
The utility model can be reached by following measures:
A kind of die casting with high-air-tightness, it is characterized in that comprising cover half, dynamic model, die frame, wherein cover half is fixed on die frame, cover half matches with dynamic model and forms the mold cavity of hollow, be provided with beam between dynamic model and cover half, cover half is provided with guide rod, and dynamic model to be enclosed within described guide rod and to slide along guide rod, described mold cavity is provided with injection port, and described injection port connects vacuum device.
The utility model is also provided with the two groups of ejecting mechanisms stretching into mold cavity, ejecting mechanism comprises boss, connecting rod, base and driving mechanism, wherein boss is connected with base through connecting rod, base is connected with driving mechanism, described boss is provided with the main body of hollow out, boss has the moulding convex surface of zigzag, carries out moulding process for the workpiece shaping to condensation in mold cavity.
Vacuum device described in the utility model comprises blast pipe, air pump, magnetic valve, and wherein magnetic valve is arranged on blast pipe, and air pump is connected with blast pipe.
Blast pipe described in the utility model is Y type discharge duct, and the injection port of the mouth of pipe and mold cavity wherein with a port is connected, and on the mouth of pipe with two ports, correspondence is connected to two groups of air pumps, magnetic valves respectively.
The utility model in use, first through injection port, process is vacuumized to mold cavity by vacuum device, then metal liquid is sent into mold cavity through injection port, because mold cavity is connected by means of only injection port with outside, the problem of the poor air-tightness can effectively avoiding gas to enter causing, have easy and simple to handle, cost is low, be easy to promote, the significant advantages such as workpiece quality can be significantly improved.
Accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model.
Reference numeral: cover half 1, dynamic model 2, die frame 3, mold cavity 4, guide rod 5, injection port 6 vacuum device 7, ejecting mechanism 8.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the utility model proposes a kind of die casting with high-air-tightness, it is characterized in that comprising cover half 1, dynamic model 2, die frame 3, wherein cover half 1 is fixed on die frame 3, and cover half 1 matches with dynamic model 2 and forms the mold cavity 4 of hollow, is provided with beam between dynamic model 2 and cover half 1, cover half 1 is provided with guide rod 5, dynamic model 2 to be enclosed within described guide rod 5 and to slide along guide rod, and described mold cavity 3 is provided with injection port 6, and described injection port 6 connects vacuum device 7.
The utility model is also provided with the two groups of ejecting mechanisms 8 stretching into mold cavity, ejecting mechanism 8 comprises boss, connecting rod, base and driving mechanism, wherein boss is connected with base through connecting rod, base is connected with driving mechanism, described boss is provided with the main body of hollow out, boss has the moulding convex surface of zigzag, carries out moulding process for the workpiece shaping to condensation in mold cavity.
Vacuum device 7 described in the utility model comprises blast pipe, air pump, magnetic valve, and wherein magnetic valve is arranged on blast pipe, and air pump is connected with blast pipe.
Blast pipe described in the utility model is Y type discharge duct, and the injection port of the mouth of pipe and mold cavity wherein with a port is connected, and on the mouth of pipe with two ports, correspondence is connected to two groups of air pumps, magnetic valves respectively.
The utility model in use, first through injection port, process is vacuumized to mold cavity by vacuum device, then metal liquid is sent into mold cavity through injection port, because mold cavity is connected by means of only injection port with outside, the problem of the poor air-tightness can effectively avoiding gas to enter causing, have easy and simple to handle, cost is low, be easy to promote, the significant advantages such as workpiece quality can be significantly improved.
