IPC: B29C45/00
Filed: 1987-10-21
Abstract: PURPOSE:To permit the impact strength of a specified part of a molded form, required to have resistance to shock, to be secured simply, by a method wherein the flow distance of resin from a gate to a cavity, corresponding to the specified part, is formed so as to be longer than the same from the gate to another cavity, corresponding to the other part. CONSTITUTION:The whole arch section 2 of a front fender 1 is required to have resistance to shock mostly since slight collisions are readily caused frequently. Therefore, a gate 4 is arranged along a cavity, corresponding to the flange part 3 of a front fender 1, to position the gate 4 as remote from the cavity, corresponding to the wheel arch 2, as possible. According to this method, resin is cast from the cavity, corresponding to the flange 3 of the front fender, and arrives at another cavity, corresponding to the wheel arch 2, whereby the flow distance of the resin becomes comparatively long. As a result, the impact resistance of the wheel arch section 2 may be increased compared with the other parts in the front fender 1.
