subject: Mould End Cap [print this page] A cap mould comprises a cap end portion engaged with an end of a mould body for a vehicle frame, a mould insert portion extending from the cap end portion and inserted in the mould body, and a hook portion provided at the mould insert portion and engaged with the mould body. In the cap mould, the hook portion comprises a first step portion having a quadrangular column shape, which has a front surface and a rear surface inclined and opposite to each other, and side surfaces each having a trapezoidal shape, and a second step portion located on an upper end of the first step portion, the second step portion having a quadrangular column or pyramid shape, which has an inclined front surface, a vertical rear surface, and side surfaces each having a trapezoidal or triangular shape.
However, in the conventional cap mould disclosed in cited reference 1 as described above, the hook portion may sway due to the elasticity of the bonding film coated on the inner surface of the mould body. Further, in the conventional cap mould disclosed in cited reference 2 as described above, because the notch portion is formed at the mould body, a secure engagement between the hook portion and the notch portion may be disturbed when any deviation in the location or size of the notch portion occurs. As a result, a gap may be generated between the end of the mould body and the cap mould, thereby degrading a desirable appearance when the cap mould has been assembled with the mould body.
Further, Cited reference 2 discloses a notch portion formed at the mould body, so that the hook portion of a cap mould is engaged with the notch portion. Therefore, when the mould insert portion is inserted in the mould body, the hook portion may be bonded to the bonding film of the mould body or engaged with the notch portion, so that the cap mould can be assembled with the mould body.
