The pressing block 301 is located below the pressing plate 3. The positioning bolt 306 is plugged into the positioning plate 305 and extends to its lower end. The pressing plate 3 is threadedly screwed to the positioning bolt 306.

[0030] The middle mold part is located inside the lower mold part, and the upper mold part is used for pressing and supporting the middle mold part.

[0031] Under the condition that the lower mold part limits the position of the middle mold part, the upper mold part is moved to press the material inside the middle mold part. At the same time, under the overall position limitation of the lower mold part on the middle mold part, the accuracy and integrity of the finished product prepared by the middle mold part are improved. Specifically, the forming support block 2 is first placed inside the bottom support frame 1, and then under the connection between the fastening groove 202 and the supporting long holes 102 on both sides, the fastening components are used to limit the forming support block 2 inside the bottom support frame 1, and then the molding material is placed inside the forming support groove 201, and then the pressing block 301 with the corresponding specifications to the forming support groove 201 is used to press and prepare the material inside the forming support groove 201 for molding. At the same time, With the limiting support of the bottom support frame 1 on the forming support block 2 and the threaded connection support of the limiting bolt 302 on the pressing block 301, the forming support block 2 and the pressing block 301 can be used as a whole to ensure sufficient pressing contact during material preparation. Moreover, according to the different specifications of the magnetic tiles to be prepared, with the support of the bottom support frame 1 and the limiting bolt 302, the forming support block 2 and the pressing block 301 can be replaced as a whole to ensure the overall smoothness of the inside of the forming support groove 201 and the outside of the pressing block 301, so that the prepared product is smooth and stable as a whole, and can improve the quality of magnetic tile preparation by the device while conveniently and economically replacing the forming support groove 201.
