| description | The invention discloses a compression molding process for a front bumper of a car. The process comprises the working procedures of sheet feeding, heating and pre-molding, pressing, annealing, coolingand sheet discharging. In the sheet feeding procedure, intermittent automatic single sheet feeding of large sheets and small sheets is conducted by using a mechanical arm, double-sheet printing is adopted for printing, the longitudinal center line of glass coincides with the center line of a male die through left-right positioning during sheet feeding positioning, and the position, where the glassreaches a female die, of the glass is changed through slight deviation of a positioning door so as to enable the glass to be centered relative to the female die. In the heating and pre-forming procedure, ten heating areas are arranged in a heating section, the first area and the second area are threaded ceramic rollers, the second area to the ninth area are smooth round rollers, and the tenth area is a fan-shaped pre-form |
