Automatic Cap Mould Machine
The present invention provides the configuration capable of automatically correcting
error in positions of assembly between the cap mould and the mould body.That is, in first aspect, the present invention provides a cap mould as defined in claim 1 comprising: a cap end portion assembled 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, wherein 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.
Further, according to a third aspect of the present invention provides a cap mould as defined in claim 3 , because the hook portion is formed at a leaf spring portion extending in an insertion direction toward the mould body, the hook portion can be pushed outward to the mould body by the elastic force of the leaf spring portion. By this, the hook portion of the cap mould can be easily engaged with the mould body.
Further, according to a forth aspect of the present invention provides a cap mould as defined in claim 4 , because the cap mould further comprises an engagement part extending in a direction perpendicular to the insertion direction toward the mould body and engaged with the vehicle frame, it is possible to engage the mould body having the cap mould attached thereto to the vehicle frame. Thus, it is possible to prevent the mould body with the cap mould from being separated from the vehicle frame. Further, because the engagement part is located near the hook portion, it is possible to reduce the entire length of the cap mould. As a result, it is possible to reduce the manufacturing cost of the cap mould.
