Two ends of the ejection driving block D430 respectively penetrate through the second ejection sliding groove D412, one end of the ejection driving block D430 is fixed with an ejection block D440, the other end of the ejection driving block D is fixedly assembled with one end of the first ejection driving shaft D210, the other end of the first ejection driving shaft D210 is provided with an ejection matching hole D211, and the ejection matching hole D211 is coaxial with the first ejection cylinder D311.

In the initial state, the tapered wedge block D420 is not fitted into the auxiliary ejection groove D431.

when the ejection device is used, the first ejection cylinder D310 is started firstly, so that the first ejection cylinder D310 drives the first ejection driving shaft D311 to move towards the ejection matching hole D211 in the axial direction until the ejection driving block D430 is driven to move towards the ejection block D440 for a certain distance after the ejection matching hole D211 is assembled, and then the first ejection cylinder stops running;

Starting a second ejection cylinder D320, driving a second ejection telescopic shaft D321 to move to an auxiliary ejection groove D431 in the axial direction by the second ejection cylinder D320 until an inclined wedge block D420 is arranged in the auxiliary ejection groove D431, and attaching a second ejection inclined surface D432 to a first ejection inclined surface D421;

and then the inclined wedge block D420 continues to move, so that the first ejection inclined surface D421 drives the ejection driving block D430 to move towards the direction of the ejection block D440 through the second ejection inclined surface D432, and the movement continues until the second ejection inclined surface D432 is matched with the highest position of the first ejection inclined surface D421. In the process, the force applied to the front surface of the ejector block can be directly applied to the wedge block D420 but not directly applied to the first ejection cylinder D310, so that the stability of the ejector block is ensured, namely the wedge block provides a support for the ejector block, and the effect of limiting and auxiliary driving is achieved.

The design can effectively avoid that the force is directly applied to the front surface of the first ejection cylinder when the front surface of the ejection block D440 is subjected to a relatively large force, so that the first ejection telescopic shaft is easy to displace to cause the ejection block to displace, the stress direction of the existing ejection state is difficult to keep unchanged, and the requirement that equipment keeps stable pressure on a workpiece in the working process can not be met. When the ejection mechanism is used for loading the clamping piece 400 into the shell 100, the clamping piece 400 is firstly aligned with the inside of the shell 100 (the clamping piece 400 is positioned below the opening end of the shell 100), then the first ejection cylinder D310 is started, the first ejection cylinder D310 partially ejects the clamping piece 400 into the shell 100 through the ejection block D440, then the second ejection cylinder D320 is started, the second ejection cylinder D320 continuously drives the ejection block D440 to completely eject the clamping piece 400 into the shell 100, stable pressure can be further ensured, and damage between the clamping piece 400 and the shell is prevented.

After the use is finished, the first ejection cylinder and the second ejection cylinder reset, so that the inclined wedge block is separated from the auxiliary ejection groove D431, and the next use can be carried out. A device capable of lifting the ejection mechanism can be provided to assist the ejection mechanism in use.
