PROBLEM TO BE SOLVED: To injection-mold a molded body which has an undercut part excellent in the quality of outward appearance even when the injection pressure on a material is made high. SOLUTION: Injection molding equipment 10 has a fixed part 12 and a movable part 14. The fixed part 12 is equipped with a fixed half 22 whereon a fixed half molding surface 24 is formed and the movable part 14 is equipped with a fixed plate 18, a support plate 34 and a movable half 52 whereon a movable half molding surface 64 is formed. A first auxiliary force 44 and a second auxiliary force 46 are fitted respectively in a first recess 36 and a second recess 38 formed in the fixed plate 18. The support plate 34 is provided with a first slide force 66 and a second slide force 68, and a first cutting die 108 and a second cutting die 134, which are slidable in relation to the support plate 34. A cavity 160 is demarcated by the fixed half molding surface 24, the movable half molding surface 64, a molding surface 77 of the first slide force and a molding surface 91 of the second slide force.
