九すばか〉で表く製品設計上の大きな問題である。(Prior art) It is necessary to attach or reinforce the bent portions of plastic products, the overlapping portions of q#VcPP bumpers, etc. to prevent deformation and stiffness. The shape of the folded part is as shown in Fig. 1, with the main plate 1 of the folded part being thinned out at a necessary angle.
[Inside inside 2! Taking as an example the case where an I-shaped board 2 is provided, in the figure, there is a rounded curved board 2 that can withstand loads from the top and bottom directions, and a lip 4 that is perpendicular to the internal projecting board 9 and that is in close contact with the inner surface of each board. Provided for reinforcement. In this case, a sink mark 1 occurs on the surface opposite to the surface on which the lip 4 is provided, so the plate material is reinforced using a thicker sheet or other parts such as metal. This countermeasure method is a major problem in product design, as it increases costs.

In order to have a space to form a lip line with wi as the boundary with the movable 1i7, a slide core is inserted, and an ejector pin is placed behind the slide core 8! Lip S is injection molded at the boundary between the movable I17 and the slide core 8 as shown in the figure.
After being cured, as shown in No. 41 [(a) and (b),
Movable II (Igi not shown) is mounted and ejector pin 9
) 6I move forward and push out the Kli product together with the slide core L. Since the ejector pin is tilted from the boundary between the movable m7 and the slide core $ toward the slide core side, move the slide core 8 to the left side in the figure. , move the slide core in the direction of separating it from the lip S, and perform the removal process.
