となく固定されることになる。Operation In the structure of the present invention described above, the connection between the mold members is performed as follows. That is, these nut bodies can be temporarily fixed to the corner contact member by screwing the screw bodies that have passed through the insertion holes from the outside into the nut bodies. Then, the nut body is inserted into the dovetail groove of the corresponding mold member in a sliding manner. Before and after this insertion movement, the flange portion is projected into the dovetail groove. Then, the screw body is tightened in a state in which both mold members are made to correspond to predetermined level positions by the insertion movement. By this tightening, the mold member is sandwiched between the nut body and the contact surface, so that the corner pad member and both mold members can be fixed. At that time, since the flange portion densely projects into the dovetail groove, the corner pad member and the two mold members are fixed to each other without being relatively displaced.

の長さ方向での正確な位置決めが容易に行える。Further, when fixing the mold member and the corner contact member by tightening the screw body, the outer peripheral surface of the protrusion comes into contact with the receiving surface of the dovetail groove forming piece, whereby the length direction of the mold member relative to the corner contact member is increased. Accurate positioning can be performed easily.

は、板厚方向の貫通孔30が形成されている。The pair of mold members 1 and 2 to be connected at right angles have the same shape and are manufactured by, for example, aluminum drawing. That is, the mold members 1 and 2 are in the shape of square rods, and dovetail grooves 10 that open to the outside are formed on each surface side in the entire length direction. The slit portion 11 opened to the outside of the dovetail groove 10 exists between the pair of forming pieces 12. An outwardly widening taper receiving surface 13 is formed between both forming pieces 12 by spot-boring or the like at a required position on both ends in the length direction of both the mold members 1 and 2. An angular contact member 20 that can be freely placed at a corner formed by both mold members 1 and 2 has a triangular plate shape and has an outer surface 1 of both mold members 1 and 2.
A pair of contact surfaces 21 and 22 that can contact a and 2a are formed by being displaced by 90 degrees. Both contact surfaces 21, 22 at the corners of the corner pad member 20.
An L-shaped flange portion 23 is projectingly provided in a side view from a position extending in between. Here, the width W 1 of the flange portion 23 is made slightly smaller than the width W 2 of the slit portion 11, so that the flange portion 23 can be densely inserted into the slit portion 11. At the two positions displaced by 90 degrees of the corner contact member 20, the insertion holes 24 opened at the contact surfaces 21, 22 while avoiding the flange portion 23,
25 are formed. Then, the screw-shaped screw bodies 26, 27 which are passed through the insertion holes 24, 25 from the outside can be screwed into the plate-shaped nut bodies 14, 15 inserted into the dovetail groove 10. The corner pad member 2
At 0, at least one abutting surface 22 and around the insertion hole 25, a protrusion having an outer constricted tape outer surface 28.
29 is integrally formed, and the taper outer surface 28 can come into contact with the taper receiving surface 13. Further, the corner pad member 20 is formed with a through hole 30 in the plate thickness direction.

での位置決めを正確に行える。Next, the work of connecting the mold members 1 and 2 in the above embodiment will be described. First, the nut bodies 14 and 15 are opposed to the contact surfaces 21 and 22 of the square pad 20, and the screw bodies 26 and 27 that are passed through the insertion holes 24 and 25 from the outside are screwed into the nuts 14 and 15 to temporarily fix them. To do. Next, the nut body 14 is inserted into the dovetail groove 10 at the end of one mold material 1. Before and after this insertion movement, the flange portion 23 is projected into the slit portion 11. After performing such insertion motion,
The corner pad 20 is moved to a predetermined level position of the mold 1. Next, the other mold member 2 is inserted into the dovetail groove 10 so that the nut body 15 can be inserted, and the flange portion 23 is inserted into the slit portion 11 following this insertion. The insertion is performed until the end surface 2b of the mold material 2 comes into contact with the outer surface 1a of the mold material 1, whereby the protrusion 29 faces the taper receiving surface 13. After mounting the corner pad 20 on the other mold material 2,
The corner pad member 20 may be attached to one of the mold materials 1 in this order. Then, the screw bodies 26 and 27 are tightened while adjusting the level position of the mold member 2 with respect to the mold member 1, for example. By this tightening, the forming piece 12 is sandwiched between the nut body 14 and the contact surface 21, so that the mold material 1 and the corner contact member 20 can be fixed, and the forming piece 12 is formed by the nut body 15 and the contact surface 22. By being sandwiched, the mold member 2 and the corner pad member 20 can be fixed. At that time, since the flange portion 23 is densely projected into the slit portion 11 of the mold material 1, the mold material 1 and the corner pad member 20 are fixed without being displaced relative to each other, and the flange portion 23 is fixed to the mold material 2 Since it densely protrudes into the slit portion 11, the die member 2 and the corner pad member 20 are fixed without being displaced relative to each other. That is, the pair of mold members 1 and 2 are connected to each other via the corner pad member 20 without any relative displacement. Further, when fixing the mold member 2 and the corner pad member 20, the taper receiving surface 13 and the taper outer surface 28 are brought into pressure contact with each other, thereby accurately positioning the mold member 2 with respect to the corner pad member 20 in the longitudinal direction. You can do it.
