Description
Technical field
The present invention relates to a kind of technical field of material formation, more particularly to a kind of die casting.
Background technology
Die casting, or claim compression casting, it is a kind of metal casting technique, it is that the liquid metal of high temperature is utilized into high pressure pressure
Enter in die cavity, the construction of die cavity is identical with product configurations to be formed, after after the liquid metal cooled and solidified in die cavity, taken
Go out, as need the workpiece of shaping.Die casting is a kind of method for casting liquid forging, a kind of in special die casting die forging machine
The technique of upper completion.Its basic craft course is：Molten metal elder generation's low speed or high-speed casting fill type and enter in the die cavity of mould, mould
There is the cavity surface of activity, it pressurizes with the cooling procedure of molten metal and forges, and has both eliminated the shrinkage porosity defect of contraction cavity of blank, also makes hair
The interior tissue of base reaches the Broken Crystal of forging state.The comprehensive mechanical performance of blank is significantly improved.
Number of patent application：A kind of die casting of 201420006559.0 disclosure of the invention, the die casting is included
The die frame of die cavity is opened up inside one, the die frame includes dynamic model and cover half, and one is connected with the die casting
Individual vacuum extractor.A vacuum extractor is connected on die casting, can be before gases at high pressure input liquid metal, will
Evacuating air in die cavity, it is not necessary to set exhaust outlet on die casting again, solves during casting forming on workpiece
The problem of stomata can be generated, the quality of Forming Workpiece is substantially increased, the security and air-tightness of die casting is improve, but
Die casting of the prior art is taken out generally by liftout attachment, but existing ejection product after product is completed
To there is efficiency in device low in ejecting product, it is impossible to the problem of rapid ejection.
The content of the invention
The present invention solves the above problems, there is provided a kind of die casting.
Technical scheme is as follows：Die casting, includes the internal die frame for offering die cavity, the die frame
Mobilizable dynamic model and fixed cover half are included, the outer wall of the dynamic model and the outer wall of cover half are closely connected the die frame
Sealing, the dynamic model coordinates the cover half that die cavity is formed between dynamic model and cover half, is additionally provided with described dynamic model and vacuumized
Device, the vacuum extractor includes exhaust tube and aspiration pump, and the exhaust tube is connected on the aspiration pump；It is described fixed
Offered inside mould connect the exhaust tube and the die cavity vacuumize runner；Oil cylinder is fixed with the wall of the cover half side, institute
State to vacuumize and be provided with by the guiding valve of the hydraulic oil cylinder driving in runner, it is characterised in that：The bottom of the die cavity is provided with angled slide block,
The angled slide block connects knock-pin, and the knock-pin is expansion link, and one end of the knock-pin is connected with die cavity.
Implementation process of the invention is as follows：Die casting is ejected into cover half, expansion link using expansion link after die casting shaping
Die casting can quickly be ejected.
Brief description of the drawings
Fig. 1 is specific embodiment structural representation.
Specific embodiment
Specific embodiment of the invention is further described below in conjunction with the accompanying drawings.

Envelope, the dynamic model 12 coordinates the cover half 11 that die cavity 13 is formed between dynamic model 12 and cover half 11, on described dynamic model 12 also
It is provided with vacuum extractor, the vacuum extractor includes exhaust tube 9 and aspiration pump 8, and the exhaust tube 9 is connected to described taking out
On air pump 8；The connection exhaust tube 9 and the die cavity 13 are offered inside the cover half 11 vacuumizes runner 15；It is described fixed
It is fixed with oil cylinder 2 on the side wall of mould 11, described vacuumizing be provided with the guiding valve 10 driven by the oil cylinder 9, its feature in runner 15
It is：The bottom of the die cavity 13 is provided with angled slide block 4, and the angled slide block 4 connects knock-pin 6, and the knock-pin 6 is expansion link,
One end of the knock-pin 6 is connected with die cavity.Guide rod 1 is provided with the cover half 11, the dynamic model 12 is set in the guide rod 1
Go up and can be slided along the guide rod 1.
Beneficial effect of the present invention is：When die casting completes product die casting, can quick ejecting product, improve its and give birth to
Produce efficiency.
