Abstract
The utility model discloses a guide type forming mould for a side roof of a passenger car. The guide type forming mould comprises an upper mould seat mounted on a hydraulic machine pressing head, an upper mould pressing body mounted on the upper mould seat, an upper mould, a lower mould seat mounted on a hydraulic machine platform and a lower mould assembly mounted on a lower mould seat, wherein the lower mould assembly comprises a lower mould and a lower mould top device; the upper mould is mounted on the upper mould seat; and at least one elastic body is arranged between the upper mould seat and the upper mould pressing body. The pressing process is divided into two phases; in the first phase, the upper mould seat drives the upper mould pressing body to move down to the bottommost end of the inwardly recessed surface of the lower mould so as to form an obtuse-angle bent part of the side roof, and the elastic body is not subjected to elastic deformation; and in the second phase, the upper mould seat continues to move down, the elastic body is subjected to elastic deformation, and the upper mould seat drives the upper mould to move down to the top of the lower mould so as to form a right-angle bent part. According to the utility model, the obtuse-angle bent part and the right-angle bent part can be formed successively through single pressing on one mould, so that the time is saved and the forming efficiency is improved.
