The inner cavity of the limit groove 301 is slidably connected to the limit block 302, and one side of the limit block 302 is fixedly connected to the limit rod 303. The inner walls of the insulation layer 201 and the metal shell 202 are fixedly connected with a guide block 304, and one side of the guide block 304 is opened with a penetrating guide hole 305. The surface of the limit rod 303 is slidably connected to the inner cavity of the penetrating guide hole 305, and one end of the limit rod 303 is fixedly connected to a handle 306.

By setting the spring 4, a reverse force can be provided to the limit block 302 when the limit rod 303 is pulled, so that when the force on the limit rod 303 is disconnected, the limit block 302 can be quickly reset by the reaction force;

[0031] Reference Figure 2 A sliding groove 5 is provided on the top of the insulation layer 201, and the inner cavity of the sliding groove 5 is slidably connected to the surface of the limit block 302. By providing the sliding groove 5, a guide function is provided for the longitudinal movement of the limit block 302, thereby preventing the limit block 302 from randomly shaking horizontally when moving, thereby increasing the stability of the limit block 302 when moving;

[0036] Working principle: When casting ferrous metal, the riser body 1 will be used. When the casting is completed and cooled, the foundry worker first moves it by pulling the handle 306. The movement of the handle 306 drives the movement of the limit rod 303. The movement of the limit rod 303 drives the limit block 302 to move. The movement of the limit block drives one end of the spring 4 to move. The other end of the spring 4 is fixed on one side of the guide hole to form an extrusion on the spring 4. When the limit block 302 moves to the position of the sliding groove 5, the metal shell 202 is lifted upward. The movement of the metal shell 202 drives the insulation layer 201 to move until the metal shell 202 and the insulation layer 201 are separated from the riser body 1, thereby realizing the separation of the insulation device and the riser body 1.
