In order to prevent the occurrence of the vibration compression process and take-out process is carried out in the direction of gravity consists of a main configuration, where the detailed description according to the block forming method will be described step by step through the contents described below.

1. Material input step (S1)

The molding material is filled in the mold 22 of the mold body 20 in which the surface mold 30 is installed at the lower portion thereof, and the upper portion is closed by the finishing member 24. Molding material (eg, mortar) is automatically input by the material supply unit 50, in which the material supply unit 50 is installed in a number proportional to the type of the molding material used to manufacture the molding (B).

In addition, in the material input step (S1), when filling at least two or more kinds of molding materials sequentially, the filling space of the molding material inside the mold 22 is adjusted according to the lifting height of the surface mold 30 so that the surface layer and the base of each molding are formed. The thickness of is precisely controlled.

In one embodiment, when molding a two-tone block representing the surface layer and the base layer in different colors, first, two or more green and blue molding materials having different colors are prepared on each material supply unit 50. Subsequently, the surface mold 30 is first lowered by a thickness (50 mm) corresponding to the surface layer based on the upper surface of the mold body 20, and then the green layer forming the surface layer into the mold 22 by the material supply unit 50. The molding material of is introduced into the primary. At this time, the thickness of the surface layer is preferably formed in 10 ~ 50mm.

Subsequently, when the injection of the surface molding material is completed, the surface mold 30 is secondly lowered by a thickness (100 mm) corresponding to the substrate based on the upper surface of the mold body 20, and then the substrate is formed by another material supply unit 50. Blue molding material constituting the secondary is injected into the secondary.

As such, since the filling space of the molding material is adjusted according to the position of the surface mold 30, the injection amount of the molding material is precisely controlled without limiting the thickness, and the molding (B) having at least two kinds of textures or colors as shown in FIGS. 2A to 2B. When molding, there is an advantage that the thickness of each layer is precisely controlled.

In addition, after the molding material is introduced by the material supply unit 50 in the above, the molding material over-injected by the scraper 60 which is transported along the upper surface of the mold body 20 is removed. Therefore, since the input amount of the molding material filled in the mold 22 is more precisely controlled, the density and thickness of each of the molded products B are uniformly maintained during mass production.

In addition, a low vibration force of 1 to 5 tons is applied to the mold main body 30 in the process of inserting the molding material, but the low vibration force acts when the filling thickness of the molding material is formed to be thicker than 250 mm so that the molding material is formed into a mold ( 22) There is an advantage that the surface layer facing the surface mold 30 is formed at a high density while being filled in the space and concentrated in the weight direction.

When the injection of the molding material is completed, the upper portion of the mold 22 is closed by the closing member 24, and the closing member 24 is pressed by a compression cylinder (not shown).

The surface mold 30 is moved up and down under the mold 22 to vibrate and compress the molding material. In the forming step (S2), the surface mold 30 is transferred upward from the lower side and pressurizes the molding material. At this time, the mold main body 20 is vibrated by the vibrator 26 to simultaneously perform the compression process and the vibration process.

At this time, while the molding material is compressed within the mold 22 by the lifting operation of the surface mold, a vibration force of 15 to 25 tons is applied, so that the fine particles are collected in the direction of gravity, that is, the surface of the surface mold 30, As the density is improved, the surface layer of the molding (B) is molded into a texture comparable to that of natural stone, and in particular, fine particles of the molding material closely adhere along the surface shape of the surface mold (30) to prevent defects due to pores and delicate patterns. There is an advantage that the implementation is realized.

3. Turning ejection step (S3)

The mold body 20 is rotated 180 degrees and the compressed molding B is pressed out from the upper side with the finishing member 24 to be taken out. Turning ejection step (S3) is the mold body 20 is rotated 180 degrees so that the finishing member 24 is located at the bottom when the compression molding of the molding material is completed by the pressing force of the surface mold (30). Subsequently, the molding B and the finishing member 24 are taken out together in the gravity direction, that is, the downward direction by the operation of the surface mold 30.

As such, as the molded article B is turned and taken out in the gravity direction, the molded article B is naturally separated from the surface mold 30 by its own weight, thereby preventing damage to the surface layer.

4. Drying step (S4)

The finishing member 24 is transferred to the drying chamber after taking out the molding (B) using a pallet. In the drying step (S4), the molded article (B) is taken out from the mold body integrally with the pallet, and is transferred to the drying chamber using the pallet as a conveying means, so that the molded article (B) is damaged or cracked by external force during the take-out and transport process. Defects such as

In addition, a concrete block forming apparatus for realizing the block forming method includes a main housing including a turning housing 10, a mold body 20, a surface mold 30, and a material supply unit 50.
