Side system for a casting mold and an attaching unit

Abstract

The invention concerns a mold system for manufacturing concrete products, said mold system comprising a mold bed, mold side, magnet unit including a magnet element for attaching the mold side to the mold bed, and a frame surrounding the magnet, whereby there is a space between the upper surface and frame of the magnet element, where the magnet can be lifted from the mold bed, and a lifting element for moving the magnet, and means for attaching the magnet to the mold side. The invention is characterized in that the magnet element is connected to the frame surrounding it by means of a flexible plate being movable with respect to the frame. The invention also concerns said magnet unit.

Claims

1. A mold system for manufacturing concrete products, said mold system comprising a mold bed, mold side, magnet unit including a magnet element for attaching the mold side to the mold bed and a frame surrounding the magnet, whereby there is a space between the upper surface and the frame of the magnet element, where the magnet can be lifted from the mold bed, and a lifting element for moving the magnet, and means for attaching the magnet unit to the mold side, wherein the magnet element is connected to the frame by means of a flexible plate being movable with respect to the frame.

2. A mold system in accordance with claim 1, wherein the flexible plate is a plate spring.

3. A mold system in accordance with claim 1, wherein the lifting element is also a means for attaching the magnet unit to the mold side.

4. A mold system in accordance with claim 1, wherein the magnet unit comprises at least one face surface equipped with a wedge profile to be adapted to the counter wedge profile of the side for attaching the magnet unit to the mold side.

5. A magnet unit for attaching a side of a concrete mold, whereby the magnet unit comprises a magnet element for attaching the mold side to the mold bed and a frame surrounding the magnet, whereby there is a space between the upper surface of the magnet element and the frame, where the magnet can be lifted from the mold bed, and a lifting element for moving the magnet, wherein the magnet element is connected to the frame by means of a flexible plate being movable with respect to the frame.

6. A magnet unit in accordance with claim 5, wherein the flexible plate is a plate spring.

7. A mold unit in accordance with claim 5, wherein the lifting element is also a means for attaching the magnet unit to the mold side.

8. A side system in accordance with claim 5, wherein the magnet unit comprises at least one face surface equipped with a wedge profile to be adapted to a counter wedge profile in the side for attaching the magnet unit to the mold side.

9. A mold system in accordance with claim 2, wherein the lifting element is also a means for attaching the magnet unit to the mold side.

10. A mold system in accordance with claim 2, wherein the magnet unit comprises at least one face surface equipped with a wedge profile to be adapted to the counter wedge profile of the side for attaching the magnet unit to the mold side.

11. A mold unit in accordance with claim 6, wherein the lifting element is also a means for attaching the magnet unit to the mold side.
