DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metallic mold used for structures, machines, devices, and the like, and to equipment used together with the mold.

[0002]

2. Description of the Related Art Conventionally, an aluminum mold material formed by extrusion has been widely used as a structural mold material. Aluminum mold materials are lightweight, have a beautiful appearance, and can be formed into a complex cross-sectional shape by extrusion, so that they are often used in places where a small load is applied and they are exposed to the outside.

In recent years, recently, an aluminum mold having a circular, square or other irregular hollow portion formed in a cross section and having a groove formed on a side having a flat cross section is used by being fitted into the groove of the mold. A combination of nuts and fixtures to connect structural members or attach panels to systematize and unitize structures is widely used.

[0004] The cross-sectional shape of the aluminum mold is as follows.
JP-A-5-302396, JP-A-7-29353
No. 6, JP-A-7-293536 and the like are typical examples. The basic shape of this type of molding is such that a cross section is square or rectangular, a circular or irregular hollow portion is formed in the cross section, and nut insertion grooves are formed on four sides. Such a shape member is used as an arm or a frame of various machines and devices, a base, a frame, and other support members of the machine.

[0005]

By the way, if a groove for inserting a nut is formed on each side of the mold from the beginning, if there is a groove in which the nut is not inserted at the stage of using the mold, the groove is consequently formed. The groove would have been unnecessary, and if this groove appeared in a portion of the completed structure that was visible from the outside, the appearance would be impaired. Further, the unnecessary grooves result in a reduction in the strength of the molding material. Further, there is a problem that dust and the like are easily accumulated in the groove, and it is difficult to remove the accumulated dust.

In order to solve such a problem, conventionally, a synthetic resin cover having a shape to be fitted into the groove is separately prepared, and the outer surface is flattened by being fitted into the unnecessary groove. . However, preparing such a separate member incurs a burden in terms of cost and also takes time to attach the cover.

[0007] Further, in order to prevent the nut from being moved in the groove when the nut is inserted into the groove of the shape when connecting the shape or mounting the plate, the nut is conventionally provided separately from the bolt hole. A method of forming a screw hole and screwing a set screw into the screw hole to press the nut against the inner surface of the groove, a method of attaching a rubber cap or a stopper, and the like are used. However, these methods are disadvantageous in terms of cost and work as compared with a single nut, and may impair the appearance.

Further, in order to mount a plate between two mold members by using a groove of the mold member, conventionally, a plate is directly attached to the mold member using bolts and nuts, or the plate is attached to the mold member by bolts and nuts. A method of fixing the plate with a bracket is adopted. However, these methods have the above-mentioned problems in fixing the nut in the groove of the mold.

The problem to be solved by the present invention is to form a groove only at a necessary portion so that unnecessary grooves do not remain at the time of connecting metallic mold members to each other or attaching a plate to the mold member. Ensure that the nut is fixed in the groove,
Another object of the present invention is to easily and reliably mount the plate.

[0010]

SUMMARY OF THE INVENTION The present invention is directed to a metal mold having a hollow section having a circular, square or other irregular shape formed in a cross section, wherein the hollow section is formed inside a side having a flat cross section. And two rows of cutout grooves extending from the inner surface of the hollow portion to the outer surface of the mold material to the middle of the thickness of the side at intervals in the width direction of the side.

In the stage of the present invention after the extrusion molding, there are no grooves open on the outer surface, and the outer surface is smooth on each side. When using a mold, a groove is formed later only on the side where a groove is necessary for connecting the molds or attaching a plate. Two rows of cutout grooves are formed inside each side having a flat cross-sectional profile so that a groove can be formed later. When it is bent, the portion is peeled off, and a hollow portion formed in advance appears as a groove.

Since the two rows of cutout grooves are used to separate the portion between the cutout grooves from the main body of the mold, if they are formed in a V-shape at a depth of at least half the thickness of the side. The grooves can be easily formed when necessary without deteriorating the strength of the side portions.

[0013] Further, the mold connecting nut of the present invention, which is used by being inserted into a groove formed on the outer portion of the mold, is characterized in that a metal elastic member is attached to the back surface of the nut body. Here, a thin steel plate or a coiled spring can be used as the metallic elastic member. When using a thin plate, the thin plate is glued to the nut body in a posture standing up from one side of the nut body, and this thin plate is bent into the back of the nut body and the nut body is inserted into the groove, Due to the elasticity, the nut body can be pressed against the outer inner surface of the groove to fix the nut so as not to move. When using a coiled spring,
With the spring interposed on the back surface of the nut body, the nut body can be pressed against the inner surface of the groove by the elasticity of the spring.

Further, the panel fixing device of the present invention, which is used by being fitted into a groove formed on an outer portion of a mold member, has two plate members facing each other standing upright at one end of the plate member. The distance between the inner surfaces of the plate-like members is reduced toward the distal end side, and a bolt insertion hole is provided in a portion corresponding to a space facing the plate-like member at one end of the plate-like body, and further, a bolt for the plate-like member is further provided. A screw groove is formed in a portion following the insertion hole.

This panel fixing device does not require the use of nuts, unlike the conventional method of attaching a bracket to a mold, and the panel fixing device can be attached to the mold by a simple operation. Specifically, two plate-like members that stand on one end side of the plate-like body are inserted into the grooves of the mold member, and bolts are inserted through the bolt insertion holes and screwed into the two plate-like members. It is spread out and pressed against the inner surface of the groove, thereby fixing the panel fixture to the profile. When inserting the plate member of the panel fixture into the groove of the mold member, the panel is hung between the two mold members, and the panel is sandwiched between the plate member of the panel fixture and the mold member. By inserting a bolt through the bolt insertion hole and screwing in, the plate is fixed to the mold together with the panel fixture.
