In the above embodiment, the molding apparatus further includes a blank pressing mechanism 700, the blank pressing mechanism 700 and the molding mechanism 200 are sequentially arranged in the moving direction of the reverse moving mechanism, and the blank pressing mechanism 700 can perform a blunt edge molding operation on the side edges of the joined upper surface and the side surfaces of the preform matrix 910 formed after the material distribution. Specifically, as shown in fig. 19 and 20, the edge pressing mechanism 700 includes a bracket 71 and a roller 73 disposed on the bracket 71; the outer wall of the roller body 73 is provided with at least two blunt edge modeling structures 74 along the axial direction, the outer wall of each blunt edge modeling structure 74 is provided with a profiling pressing surface 74a matched with a blunt edge on the prefabricated part 900, and the profiling pressing surfaces 74a on two adjacent blunt edge modeling structures 74 are arranged oppositely or back to back.

The profiling pressing surface 74a fitted to the blunt edge of the preform 900 acts on the preform 900 after the preform 900 is distributed to form the blunt edge. When the profiling pressure surfaces 74a of two adjacent blunt edge modeling structures 74 are oppositely arranged, the diameter of the profiling pressure surface 74a of one blunt edge modeling structure 74 gradually decreases in a direction toward the profiling pressure surface 74a of another blunt edge modeling structure 74 in the same group, that is, the diameter of the profiling pressure surfaces 74a of two blunt edge modeling structures 74 is gradually decreased from outside to inside (wherein, "outside" means a side away from the other blunt edge modeling structure 74, and "inside" means a side close to the other blunt edge modeling structure 74); when the profiling pressure surfaces 74a on two adjacent blunt edge contouring structures 74 are arranged oppositely, the diameters of the profiling pressure surfaces 74a of two blunt edge contouring structures 74 are both tapered from inside to outside.

In general, the upper surface of the prefabricated member 900 has two side edges, and the embodiment will be described by taking an example in which the profiling pressing surfaces 74a of two adjacent blunt edge forming structures 74 are opposed to each other. When the prefabricated part 900 side edge rolling device is used, the support 71 drives the roller body 73 to move along the length direction of a mold for producing the prefabricated part 900, the blunt edge modeling structure 74 is driven to move along the length direction of the preformed prefabricated part 900 side edge, friction force in the moving process can drive the roller body 73 to rotate, the blunt edge modeling structure 74 is driven to roll along the upper surface of the prefabricated part 900, the rolling blunt edge can achieve the rolling effect, and the problems that the rough surface, the stacking material and the like are caused by the fact that the preformed prefabricated part 900 surface concrete is brought up in the moving process are avoided. In the rolling process, the profiling pressure surfaces 74a of the two blunt edge modeling structures 74 can perform blunt edge modeling on two edges of the upper surface of the prefabricated part 900, because the diameter of the profiling pressure surfaces 74a is gradually reduced from outside to inside, therefore, after the profiling pressure surfaces 74a and the edges of the prefabricated part 900 act, the edges of the prefabricated part 900 can form gradually reducing structures matched with the profiling pressure surfaces 74a, such as a chamfer, a fillet and the like, so that the structure on the surface of the prefabricated part 900 is more regular and attractive, and sharp corners are avoided simultaneously, the condition that collision and the like with other objects are caused to damage can be avoided in the hoisting or transportation process, and the improvement of the integrity of the prefabricated part 900 is facilitated.

In the above embodiment, a circumferential positioning structure is disposed between the roller body 73 and the blunt edge modeling structure 74 to limit relative rotation between the two, so as to ensure that the rotation of the roller body 73 can drive the blunt edge modeling structure 74 to rotate, thereby avoiding the slipping between the roller body 73 and the blunt edge modeling structure 74.

In the above embodiment, the blunt edge molding structure 74 further includes an end surface 74b facing away from the profiling pressure surface 74a, the profiling pressure surface 74a is connected with the end surface 74b, and the end surface 74b is gradually close to the profiling pressure surface 74a in a radial direction away from the central axis of the roller body 73, in other words, the end surface 74b is connected with the large diameter end (i.e., the end far away from the preform 900 where the diameter is the largest) of the profiling pressure surface 74a, and in the present embodiment, at least one of the profiling pressure surface 74a and the end surface 74b is provided with a wear-resistant coating (e.g., teflon, etc.), and preferably both are provided with wear-resistant coatings. Specifically, when the upper surface side edge of the prefabricated part 900 is subjected to blunt edge modeling operation, the end face 74b can be attached to the inner wall of a side die of a die for molding the prefabricated part 900, the profiling pressing surface 74a acts on the side edge formed by the upper surface and the side surface of concrete poured in the die, rolling is performed along the extension direction of the side edge, the two side edges of the upper surface of the prefabricated part 900 form a blunt edge structure, in the moving process, the profiling pressing surface 74a and the end face 74b have the problem of friction, and due to the arrangement of the wear-resistant coating, the wear resistance of the profiling pressing surface 74a and the wear resistance of the end face 74b can be improved, and the service life is ensured.

In addition, in this embodiment, the contour generatrix of the profiling pressure surface 74a includes at least one straight line segment and/or at least one arc segment, and the specific shape of the profiling pressure surface 74a is not limited, as shown in fig. 25 to 27, the acting surface of the profiling pressure surface 74a may be an inclined surface, an arc surface, or a combination of the inclined surface and the arc surface.
