The sliding plate 2.9 is also provided with a whole circle of material leaking grooves, a plurality of material leaking holes are arranged at intervals along the material leaking grooves, so that leakage glue materials can flow away in time conveniently during movement, and the sliding plate 2.9 sliding rail is not polluted to influence the service life of the sliding plate.

This embodiment adopts quick connect latch 2.6 to connect connecting block 2.5 and slide 2.9, when pouring head integrated ground slide 2.9 group will dismantle the washing and back-up, and is quick convenient.

The second protective organ cover 2.22.2 of this embodiment prevents that the servo drive electric cylinder 2.1 from coming out of the pole and receiving the pollution of the interior sizing material volatile substance of vacuum pressure casting jar, extension servo drive electric cylinder 2.1 life.

The servo drive electric cylinder 2.1 and the sliding plate 2.9 are fixedly connected through the hanging piece, and the overhanging of the servo drive electric cylinder 2.1 and the sliding plate 2.9 is avoided, so that the mechanism operates more stably and reliably.

It should be noted that, although the above embodiments have been described herein, the invention is not limited thereto. Therefore, based on the innovative concepts of the present invention, the technical solutions of the present invention can be directly or indirectly applied to other related technical fields by making changes and modifications to the embodiments described herein, or by using equivalent structures or equivalent processes performed in the content of the present specification and the attached drawings, which are included in the scope of the present patent.
