記載のＶＴＲカセツトケースのガードパネル成形
用金型。[Scope of Claim for Utility Model Registration] (1) In a mold for a guard panel of a VTR cassette case, the short side of the molded product with an L-shaped cross-section is used as the gate part, and the undercut part of the cross-sectional shape is forced. A guard panel molding tool for a VTR cassette case, characterized in that the undercut part is inclined at an angle of 30 degrees or less with respect to the mold thickness direction so that the slide core can be eliminated so that the undercut part can be removed. Type. (2) When applying grain only to the short side of the cross-sectional shape of the molded product, or to both the long and short sides, make sure that the grained surface is formed at an angle of at least 3° to the mold thickness direction. Claim (1) characterized in that
A mold for forming the guard panel of the VTR cassette case described above.
