Abstract

PURPOSE:To enable to perform driving of clamping and breaking of a mold and a cut-off punch of a hoop material by one driving source and to enable to perform reliably holding of positioning of the hoop material, by a method wherein a mold punch is held under a state wherein a metal piece is blanked and the metal piece is held by the mold punch. CONSTITUTION:A hoop material 11 is positioned by a pilot pin 15 by clamping a top force body 1 and a bottom force body 2. In this instance, the hoop material 11 is held by the top force body 1, a cut-off block 17, a cavity block 4 and a holding pin 6 of the hoop material. Then a cut-off punch 16 is made to descend by descending a mounting plate 3 of the top force body 1 further, an end part of the hoop material 11 is cut off by the cut-off punch 16 and the cut-off block 17 and the end part of the hoop material 11 is held by the cut-off punch 16 by leaving a state behind as it is. Co-molding of the hoop material 11 is performed by pouring resin through a resin pouring port 7 under the above state. When the resin is cured, the top force body 1 and the bottom force body 2 are broken, an ejector pin is made to protrude and the molded article is taken out by raising the same.

When the hoop material 11 is fed through the hoop 1, the upper mold body 1 and the lower mold main body 2 are closed as shown in Fig. M3, and the hoop material 11 is positioned using the pilot bin 15. At this time, the upper mold body 1, the cutting block 17, the cavity block 4, and the hoop material holding bin 6 hold the hoop material 11. Note that the lowering of the upper mold body 1 is performed by lowering the upper mold presser plate 3 halfway, and then the upper mold body mounting plate 3 is further lowered to lower the cutting punch 16 (the fourth
(Fig.), the end of the hoop material 11 is cut by the cutting punch 16 and the cutting block 17 trap, and the end of the hoop material 11 is held by the cutting punch 16 in the state of '-'. 11' is a punched piece of the hoop material 11. In this state, resin is injected from the resin injection lower, and the hoop material 11 is simultaneously molded. When the resin hardens, the upper mold body 1 and the lower mold body 2 are opened (Fig. 5), the ejector pin 8 is protruded, and the molded product 18 is removed.
Lift it up and remove it in the direction of arrow A.

備が簡単なもので済む。Forming is performed in this way, but since the cutting punch 16 stops at the punched position and holds the hoop material 11, the hoop material 11 does not move due to molding pressure, etc., and remains at a predetermined position. Simultaneous molding is possible. In this case, as in this embodiment, the cutting punch 1
Assuming that 6 punches the hoop material 11 into a substantially trapezoidal shape, 2
The movement of the 7-pipe member 11 can be prevented against force from the direction, and the movement can be prevented even more reliably. Further, since cutting is performed by the cutting punch 16 before closing the mold, opening and closing of the mold and driving the cutting punch 16 can be performed by one drive source, and the equipment can be simple.

なお、前記実施例ではフープ材１１を用いたが、他の金
