Specific embodiment
More detailed description is done to the embodiments of the present invention below in conjunction with attached drawing and appended drawing reference, makes to be familiar with ability
The technology people in domain can implement accordingly after studying this specification carefully.It should be appreciated that specific embodiment described herein is only to solve
The utility model is released, is not used to limit the utility model.
Referring to Fig. 1, a kind of injection mold with air-flow assisting demolding device, including quiet mould 1, the dynamic model 2 being oppositely arranged,
Die cavity 3 is formed between the quiet mould 1, dynamic model 2, and demoulding frame movable chamber is formed between the dynamic model 2 and the first support frame 5, it is described
It is provided with thermal insulation board 4 between demoulding frame movable chamber and the dynamic model, is formed between first support frame 5 and the second support frame 6
Expansion bracket movable chamber 20；Oil cylinder 7 is provided at the center of second support frame 6, the oil cylinder 7 is connected with telescopic rod 8, described
Telescopic rod 8 passes through first support frame 5 and extends to demoulding frame movable chamber, and the telescopic rod 8 is with connecting plate 9 in demoulding frame activity
Intracavitary connection, the connecting plate 9 are connected at least two demoulding frames 10, and end plate 13 is provided on the demoulding frame 10, described
Demoulding frame 10 passes through the dynamic model 2 and extends in the stripping chute 12 being arranged on dynamic model 2；The connecting plate 9 and the dynamic model 2 it
