Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete product forming frame device, and more particularly to a device for forming a desired pattern on a surface portion of a concrete product when the concrete product is formed.

[0002]

2. Description of the Related Art Conventionally, a mold device for molding concrete products mainly comprises one mold body and the other mold body which is provided so as to be movable back and forth with respect to the one mold body. Then, the one mold body and the other mold body are combined to form a cavity for molding a concrete product, and a desired concrete product is molded in this cavity.

On the other hand, recently, depending on the type of concrete product, it is desired to form a desired pattern on the surface of the concrete product. In such a case, the pattern mold is placed and fixed to one mold or the other mold at a position corresponding to the surface portion required to mold the pattern, and this pattern mold is used to mold concrete products. It constitutes the cavity.

[0004]

A mold device for forming a desired pattern on the surface of a concrete product using the pattern template comprises a pattern mold for forming the desired pattern on the surface of the concrete product. Since the dedicated formwork device is uneconomical, if the pattern form is placed on an existing formwork device that does not form the desired pattern on the surface of the concrete product, one of the thickness dimensions of this pattern form will There is a problem that the shape of the cavity formed by the mold body and the other mold body is insufficient, and it is not possible to mold the concrete product having the shape and size that can be molded by the existing mold frame device.

Therefore, the present invention has been made in view of the above point, and even when a pattern mold is arranged between one mold and the other mold, the present invention can be applied to the surface of a concrete product. It is possible to reliably form a concrete product having a predetermined shape and a desired pattern, and therefore it is possible to form a desired pattern on the surface of a concrete product using an existing formwork device. The object is to provide a mold device for molding a concrete product.

SUMMARY OF THE INVENTION A concrete product forming frame apparatus of the present invention is a concrete product between one mold body and one mold body that is movable back and forth. The other mold body forming a cavity for molding,
A pattern mold body that is detachably disposed between the one mold body and the other mold body, and the one mold body is provided on its left and right portions toward the other mold body. The left and right brackets each have a protruding mounting bracket, and the left and right brackets are formed with a first mounting hole and a second mounting hole, respectively, which are spaced from each other in the advancing and retracting direction of the other mold body. Of the first mounting hole and the second mounting hole of the second mounting hole, the connecting metal fittings having the hook portions at the tip end are rotatably and detachably mounted on the support shaft. The other mold body has brackets facing the left and right parts thereof, and between the left and right brackets, there are an engaging protrusion and a handle which are removably engaged with the hook parts of the left and right connecting fittings. The connecting rod is rotatably mounted on the left and right parts located at the rear of the connecting rod. A guide metal fitting having a guide for pushing the left and right connecting metal fittings toward the connecting rod is provided, and the left and right depending on the presence or absence of a pattern shape body arranged between the one mold body and the other mold body. The connecting metal fitting is selectively axially attached to the first mounting hole or the second mounting hole.

[0007]

In the concrete product forming frame device of the present invention, when a desired pattern is formed on the surface of the concrete product, the left and right brackets of one of the molds are provided with the respective first mounting holes. The left and right connecting fittings are pivotally attached to the respective pivots. Further, the pattern mold is detachably disposed and supported on the other mold by the fixed mold plate located on the one mold side.

Next, when the other mold body is advanced toward the one mold body, the guides of the left and right guide metal fittings of the other mold body engage with the left and right connecting metal fittings of the one mold body, and The left and right connecting fittings are pushed by the guide toward the connecting rod of the other mold body, and the hook portions of the left and right connecting fittings are engaged with the left and right engaging projections of the connecting rod.

When the connecting rod is rotated by the handle of the connecting rod, the left and right engaging projections of the connecting rod are rotated, and the hook portions are engaged by the left and right engaging projections. The left and right connecting fittings are rotated around their respective support shafts, and the left and right connecting fittings are simultaneously pulled while being separated from the guides of the left and right guide fittings, while the other mold advances toward one mold. Then, the pattern mold supported by the fixed mold plate of the other mold is joined and fixed in a liquid-tight state to the mold matching portion of one mold to mold the mold. Then, the molding surface of one mold body and the pattern mold surface formed on the surface portion of the pattern mold body of the other mold body form a cavity for molding a concrete product having a desired shape and dimension.

Next, when the concrete product is cast in the cavity and is cured after being molded and cured, the handle of the connecting rod is used to rotate the connecting rod in the opposite direction to that at the time of mold matching. The left and right connecting fittings engaged with the hooks by the left and right engaging projections of the connecting rod are rotated toward the guides of the left and right guide fittings about the respective spindles, and are guided by the guides of the left and right guide fittings. When the left and right connecting fittings come into contact with each other, the left and right engaging projections of the connecting rod are disengaged from the hooks of the left and right connecting fittings, and the lock of the mold fitting state of one mold body and the other mold body is released. .

Further, when the other mold body is retracted from one mold body, the pattern mold body of the other mold body is demolded from the concrete product, and when the concrete product is taken out, the surface portion of the concrete product at a predetermined position is removed. , A desired pattern is formed and displayed on the pattern surface of the pattern body.

Next, when molding a concrete product without using a pattern mold, the left and right connecting fittings are removed from the first mounting holes of the left and right brackets of one mold, and the left and right brackets are removed. The connecting fittings are pivotally supported by the support shafts in the respective second mounting holes. Then, as in the case of forming a desired pattern on the surface portion of the concrete product at a predetermined position, when the other mold body is advanced with respect to one mold body, the other mold body is aligned with the other mold body. Is
In addition, the mutual mating state is locked by the left and right connecting fittings and the left and right engaging projections of the connecting rod. Thus, a cavity for molding a concrete product having a predetermined shape is formed by the molding surface of one mold body and the fixed mold plate of the other mold body.
