The upper surface of workbench is additionally provided with connection workpiece, and the lower end of the workbench is installed with moving platen, under moving platen
End is also connected by expansion link with lever, and the upper end of the lever also slidably connects threaded, and the activity edge mandrel leads to
The inner surface that moving block is fixedly mounted on moving platen is crossed, mould insert, the preceding mould before being provided with the upper surface of activity edge mandrel
The lower end of insert is also connected by neck with ejector sleeve, and the lower end of the ejector sleeve is connected with core plate.
As a kind of preferred technical scheme of the utility model, the two sides of the activity edge mandrel are installed with branch
Support seat.
As a kind of preferred technical scheme of the utility model, limited location is also fixedly mounted in the lower surface of the workbench
Plate.
As a kind of preferred technical scheme of the utility model, the front of the activity edge mandrel is also installed with backhaul
Bar, the two ends of the push back pin are slidably connected with ejector sleeve.
Compared with prior art, the beneficial effects of the utility model are：The secondary ejecting mechanism of the large-sized plastic rubber mould, leads to
Setting ejection push pedal is crossed, elastic force is provided using flat spring, ejection push pedal is moved back and forth, is driven and pushed up by springing push rod fixed plate
Bar is moved up and down, and reaches the purpose for moving back and forth workbench, and uses annular push pedal mobile work platform again, when connection workpiece
During ejection, connection workpiece, can be with loose plug because product has certain enclasping force to loose plug by four ejector sleeve ejections
Travel forward together, so in the ejection process of second stage, moving platen can overcome outside to the sticking to mould power of insert, activity
After insert stop motion, workpiece is continued up into ejection using dynamic model block, the workpiece made progressively disengages loose plug, complete ejection
Motion, it is to avoid the occurrence of plastic mould adhesion, improves the production efficiency of plastic mould.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Embodiment：
Fig. 1 and Fig. 2 are referred to, the utility model provides a kind of technical scheme：A kind of Double-ejection of large-sized plastic rubber mould
Mechanism, including ejection push pedal 1 and activity edge mandrel 14, the upper surface of the ejection push pedal 1 is installed with flat spring 2, described
The upper surface of flat spring 2 is also installed with push rod fixed plate 3, and push rod 4, institute are also inlaid with the inner surface of push rod fixed plate 3
The upper end for stating push rod 4 is connected by swivel bolt with splayed centering block 20, and the splayed centering block 20 is embedded in support backing plate 5
