2. Description of the Related Art These tape-shaped materials are manufactured by continuously press-forming a plate-shaped material made of a thermoplastic resin using, for example, an apparatus shown in FIG. That is,
The plate-like material 2 made of a thermoplastic resin sent out from the winding roll 1 is introduced into a heating furnace 3 and preheated, and then enters a press molding die 4. Pressed there,
After the container portion 6 having the flange portion 5 on the periphery of the opening is formed into a tape-shaped material 7 having a shape in which a large number are continuously provided in the flow direction,
In the intermittent feeding device 8, the flange portion 5 is clamped so as not to touch the container portion 6, and intermittently transferred by a predetermined length by the air feeder 9 to repeat press forming. The obtained tape-like material 7 is cut at the flange portion 5 as necessary, separated and taken out as individual molded containers (not shown). Conventionally used press forming dies are shown in FIG.
As shown in FIG. 2A, a male mold 42 having a press piston 41 and a female mold 44 having a piston hole 43 into which the press piston 41 is fitted are provided. The resin plate-like material is stretched toward the piston hole 43 by the action of the press piston 41, and the bottom of the container 45 is sandwiched between the press piston 41 and the protruding rod 46 at the bottom dead center to match the shape of the press piston 41. After the container portion 45 is formed by being cooled in the state,
As shown in (b), the operation of releasing the container part 45 by pushing out the container part 45 by the protruding rod 46 provided at the bottom of the piston hole 43 has been repeated to form a tape-shaped material.

However, in this mold, since the mold release of the container part 45 relies on the forcible push-up by the protruding rod 46, the molded article may be deformed or damaged. As shown in c), when forming the container portion 52 having the irregularly shaped portion 51 rising upward on the bottom surface, the tip shape of the protruding rod 53 must also be formed in accordance with the bottom shape of the irregularly shaped portion 51. In order to prevent the tip 54 of the protruding rod 53 from being pushed up smoothly and to prevent the tip 54 from being caught on the bottom surface of the irregularly shaped portion 51 during feeding, the opening angle θ of the bottom surface and the angle R of the rising portion are increased. I had to keep it. For example, when the opening angle θ becomes 120 ° or less or the rising angle R becomes 0.5 mm or less, the tip 54 of the protruding rod 53 easily hits the bottom surface of the odd-shaped portion 51, and the product rate is remarkably reduced. Therefore, an object of the present invention is to prevent the deformation or breakage of the container portion by allowing the tape-shaped material to be released from the mold without directly touching the container portion. 0.5mm, opening angle θ is 90 ~ 1
An object of the present invention is to provide a press-forming die capable of efficiently and efficiently manufacturing a tape-like material having a container portion having a deformed portion having a sharp cross section of 20 ° with high accuracy.
