Description

In the present invention, machine tools for molding concrete stones in opening molds provided with plug-in cores, the latter tilting on a special hinge from one step of the machine to another, while the cores are somewhat moved out of the mold, making it easier to remove them from the mold.

The machine shown in the schematic drawing has the following device.

Mobile on wheels 1, 1, frame 2 has two stages 3, 4, on which form 6 pivots on hinge 5, the bottom and walls of which are connected pivotally, and the top open part is closed with sphero, iaJJ |, its backing board 6 held when the mold is turned by the pin 8. The front and the single walls of the mold have through holes for the cores 9, 10, provided for convenience of operation with handles P. 12.

Upon filling with concrete or some other plastic mass of form b, the latter is tightly covered with board 7 and tilted onto the lower step of the machine. The cores, resting with their protruding ends into the vertical wall of the machine step, are slightly pushed out and easily removed from the mold, after which the latter is opened and the finished stone left on the board 7, on it also belongs to the platform for drying the stones, the shape is turned back on top stage and proceed to making the next stone.

The subject of the patent.

A machine for molding concrete stones by tamping concrete in a form provided with plug-in cores, the bottom and walls of which are knitted hingely, characterized in that in order to facilitate tilting the fore 14, the upper part of the frame bearing the form is made in two steps and the form is harnessedly attached to the top, on which lies, facing open with its side upwards, during tamping, while the vertical wall, during tilting the form together with the oh it at the end of compacting underlay board, for focusing ends protruding from the mold core in order to facilitate pulling the latter.
