[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] like Figure 1 The safety hook device shown includes a linear drive mechanism 20, a transmission mechanism 30, and a safety hook 40 for fixing to the top of the molding frame 10. The safety hook 40 is rotatably suspended on the molding frame 10. One end of the safety hook 40 is connected to the transmission mechanism 30, and the other end can rotatably extend to the underside of the mold 50 inside the molding frame 10 to hook the mold 50 and prevent it from slipping. The linear drive mechanism 20 is connected to the safety hook 40 through the transmission mechanism 30 and is used to drive the safety hook 40 to rotate.
