[0016] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0017] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0018] like Figure 1-2 As shown, this embodiment provides a furnace core brick production mold, including a mold body 100 and a movable die head 200. A cavity is constructed in the mold body 100, and a movable bottom plate 300 is provided at the bottom of the cavity. The bottom plate is driven by a first power member, and a retractable core 400 is penetrated on the bottom plate; the movable die head 200 is arranged above the mold body 100, and the movable die head 200 is driven to retract by a second power member 210, and a protrusion 201 is provided on the side of the movable die head 200 facing the cavity. Further, a convex edge connected to the bottom of the mold body 100 is provided on the edge of the movable bottom plate 300.

[0019] When in use, the movable bottom plate 300 and the mold cavity can enclose a semi-enclosed space for accommodating raw materials, and then the raw materials are compacted in the space by the movable die head 200 to form an embryo. The embryo can be taken out of the mold cavity by lowering the movable bottom plate 300, and then the core body 400 is lowered to a state flush with the movable bottom plate 300, and then the embryo can be removed.

[0020] In order to facilitate the core 400 and the movable bottom plate 300 to move independently, the core 400 is set to penetrate the movable bottom plate 300, and the core 400 is driven by the third power member 410, and the third power member 410 is fixedly connected to the movable bottom plate 300. When the first power member drives the movable bottom plate 300 to move, the movable bottom plate 300, the third power member 410 and the core 400 can be raised and lowered synchronously. When the movable bottom plate 300 is lowered to the demolding position, the third power member 410 drives the core 400 to pull out the movable bottom plate 300, so that the embryo will not be blocked by the core 400. Further, the core 400 has four roots.

[0021] Furthermore, the second power member 210 and the third power member 410 are both cylinders, the first power member includes a screw rod 510 and a nut 301, nuts 301 are provided at the four corners of the movable base plate 300, the screw rod 510 corresponds to the nut 301 one by one, and the screw rod 510 is driven by the motor 500.
