Abstract

PROBLEM TO BE SOLVED: To drastically improve the manufacturing efficiency, and reduce the manufacturing cost by a method wherein when a concrete block is removed from a die, the face cell surface of the concrete block is scraped by a dressing blade being attached to the end part of a partitioning plate. SOLUTION: When a press forming is completed, a laterally bridged finger F is pulled out from the upper surface of a pallet P by retracting the laterally bridged finger F on the pallet P backward. Then, in the last, the pallet loading a molded article Y is lowered by a vertically moving device, and at the same time when the lowering is started, an upper die U is pushed downward. By doing so, the molded article Y is pushed out downward, and under a state wherein the molded article Y is mounted on the pallet P, the pallet P is set on a carrying conveyor 23 being directly under, and after the molded article Y is taken out, the molded article Y is carried to a curing and drying furnace in the following process. When the molded article Y is removed from the die, at the lower end part of an internal partitioning plate 14, a dressing blade 15 is attached, and for this reason, the molded article Y is pushed out downward, and the face cell surface 7 of the molded article Y is scraped by the dressing blade 15.

The horizontal finger F is pushed into a fitting groove 22 formed in a notch at a front and rear position of the lower end of the vibration form K, and is inserted and removed freely. Note that, in FIG. 8, the horizontal finger F is illustrated as being separated from the lower portion of the vibration form K for convenience, but in reality, it is located at the back of the vibration form K and can be moved back and forth freely. Supported.

Therefore, based on the above-mentioned components,
An outline of a manufacturing process for manufacturing four molded articles of the concrete block B at one time will be described with reference to FIGS. 11 to 17. First, the molding frame S is placed inside the vibration frame K as shown in FIG.
11 and then set as shown in FIG. 11 and actuating a drive motor (not shown) of the vibration press molding machine to form the vibration form K.
When the molding is started under the condition that the vibration is applied, first, the pallet P is pushed up from the lower part of the vibration form K by an elevating device (not shown), and as shown in FIG. Vibration form K including molding form S at P
Close the bottom of the.

Next, from the rear side of the vibration press molding machine, as shown in FIG.
The horizontal finger F shown in FIG. 0 is extruded onto the pallet P, and this constitutes the lower mold part of the vibration form K as shown in FIG. Then, the material box (not shown) of the forming material X is pushed right above the vibration form K, and the forming material X of the material supply box is poured into the inside of the forming form S and filled. , Retract the supply box.

When the molding base S is filled in the molding frame S as shown in FIG. 14, the upper mold U is pushed down from the upper part of the vibration press molding machine and descends to form the molding frame S. Core 15, half core 16, partition plate 11, core partition plate 1
The upper surface of the molding base X other than the portion 2 is pressed and pressed as shown in FIG. As a result, the molding base X is press-press molded while vibrating.

When the press forming is completed, first, the horizontal finger F on the pallet P is moved backward to move,
The horizontal fingers F are pulled out from the upper surface of the pallet P as shown in FIG. Finally, the pallet P on which the molded product Y is placed is started to descend by an elevating device (not shown), and at the same time, the upper mold U is pushed downward to push the molded product Y downward, as shown in FIG.
