Further, the mounting member 24 is provided with a mounting structure 241 for detachable mounting, and the mounting member 24 is detachably mounted on the base of the precast slab extrusion die by means of the mounting structure 241. In some embodiments, the mounting member 24 can be mounted by a connecting member, and the mounting structure 241 is a necessary basic structure required for mounting the corresponding fastener, for example, a screw connecting hole in a screw connection. In some embodiments, the mounting member 24 is mounted by a form fit, and the mounting structure 241 is a structure corresponding to the corresponding fitting surface, for example, a shaft body is disposed on the mounting member 24, the mounting surface is provided with a hole adapted to the shaft body, and the shaft body of the mounting member 24 is inserted into the hole on the mounting surface to realize mounting, where the mounting structure 241 refers to the shaft body portion disposed on the mounting member 24. In some cases, the corresponding mounting structure 241 does not necessarily refer to a partial structure when mounting is performed by form fit, for example, the mounting structure 241 may be the mounting member 24 itself when the mounting member 24 as a whole is mounted in fit with the base of the precast slab extrusion die.

In extrusion molding, a molding material is injected into an extrusion die for a prefabricated slab to form a high-pressure environment, and maintenance of a core mold assembly is sometimes required. The mounting member 24 is detachably fixed to the base of the extrusion die for a prefabricated slab, and can facilitate the disassembly and assembly and maintenance of the core mold assembly.

Further, the fixing member 21 has a bottom surface 211 facing the side of the core mold 1, a top surface 212 facing away from the side of the core mold 1, and opposite side surfaces 213 between the bottom surface 211 and the top surface 212; the second end of the first connecting rod 22 is fixedly connected with the bottom surface 211 of the fixing member 21; the first end of the second connecting rod 23 is fixedly engaged with the side surface 213 of the fixing member 21; the mounting piece 24 is biased toward the core mold 1 side with respect to the side surface 213 of the fixing piece 21.

Further, the side surface 213 of the fixing member 21 specifically includes a first side surface 2131 and a second side surface 2132; the top surface 212 of the fixing member 21 has a first slanted top surface 2121 on the side of the first side surface 2131 and a second slanted top surface 2122 on the side of the second side surface 2132. When the molding material enters the extrusion die for the prefabricated plate, the first inclined top surface 2121 and the second inclined top surface 2122 have a shunting function, so that the flowing molding material is more uniform in the channel, and the extrusion molding is facilitated.

The screw 3 passes through the core mould 1 from the bottom and extends into the first end of the first connecting rod 22. Therefore, the screw 3 does not affect the shape of the molding surface 13 and the transition surface 14 of the core mold 1.

Further, a limiting block 221 is arranged on an end surface of the first end of the first connecting rod 22; the core mould 1 is provided with an upper end surface 11 matched with the end surface of the first end of the first connecting rod 22; the upper end surface 11 is provided with a limiting groove 12 matched with the shape of the limiting block 221. When the end surface of the first end of the first connecting rod 22 is attached to the upper end surface 11 of the core mold 1, the stopper 221 is located in the stopper groove 12, so that the core mold 1 and the first connecting rod 22 are prevented from rotating relative to each other, thereby ensuring the consistency of the hollow structure of the extruded product.
