DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a formwork for forming blocks.

[0002]

2. Description of the Related Art Conventionally, a formwork used for manufacturing a sliding block for a retaining wall (hereinafter referred to as a sliding block) includes a front mold for forming a front surface of the sliding block and a side surface for forming a side surface. It is formed with a mold.

[0003] Since strength and good surface finish are required on the front of the intellectual block, the front block is installed with the front block down, and the side block is placed above the front block so as to surround the outer periphery of the front block. To form a casting space, inject ready-mixed concrete into the casting space, solidify it halfway by shaking etc. to form a block, move the side mold upward, remove it from the front mold, and mold The mold was later removed from the intellectual block and was commercialized after complete solidification by curing.

[0004]

However, in the above-mentioned mold, there is a problem that a space for moving the side mold upward and a side-type lifting device are required, and the manufacturing equipment becomes large.

[0005]

Therefore, according to the present invention, a front mold for forming the front of a sling block is installed below, and a horizontal pivot is provided near the outer periphery of a pair of opposed peripheral edges of the front mold. And a lower end edge of a side mold for forming a side surface of the sling block is rotatably mounted on the horizontal pivot shaft.

Further, the present invention has the following features.

[0007] Vertical pivots are respectively installed near the outer sides of a pair of peripheral edges of the front type that are not close to the horizontal pivots, and stepped portions extending from the front of the Shichi block to the vertical pivots. The lower edge of the stepped lower mold for molding the lower part of the part is rotatably mounted.

[0008] The stepped lower mold and the side mold are interlocked via a wedge body vertically suspended from the lower surface of the side mold.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, a lower end edge of a side surface type forming a side surface of a sliding block is rotatable about a horizontal pivot shaft which is provided near an outer side of a front peripheral edge arranged below. By attaching, the side mold is turned inward to form a mold, and the side mold is turned outward,
The upper part of the front mold can be expanded to take out the intermediate block formed in the mold.

[0010] Therefore, the space for moving the side mold and the lifting device are not required, the manufacturing device for the sling block is reduced in size, and the equipment for manufacturing the sling block is reduced in size.
Capital investment can be reduced.

[0011] Further, during the removal operation of the sling block, there is a possibility that a part extending rearward from the front of the sling block may be lost due to the outward rotation of the side mold. The above-mentioned loss can be prevented by using a stepped lower molding die having a lower end edge rotatably attached to the pivot and releasing it by rotating in a different direction from the side die.

In addition, a wedge body is suspended from the lower surface of the side mold, and the stepped lower mold and the side mold are linked through the contact between the wedge body and the stepped lower mold, so that the side mold is moved inward. When turned,
The stepped lower mold rotates inward to form the lower part of the mold,
When the side mold is rotated outward, the operation of the stepped lower mold is automated by rotating the side mold to the outer demolding position.
