    • To reduce variations in quality of a molding product. An injection molding machine (10) includes a control device (700) . The control device (700) includes a rotation control unit (713) and an adjusting unit (715). The rotation control unit (713) rotates in a predetermined direction to move a first mold unit (800A) in a first section (1701) from a first position (P1) to a second position (P2), to move the first mold unit (800A) in a second section (1702) from the second position (P2) to a third position (P3), and rotates in a direction opposite to the predetermined direction to move the first mold unit (800A) in a third section (1703) from the third position (P3) to the first position (P1). The adjusting unit (715) reduces a time difference among a first time until the first mold unit (800A) moves in the first section (1701) and a second process starts at the second position (P2) after a predetermined time elapses from when a first process starts at the first position (P1), a second time until the first mold unit (800A) moves in the second section (1702) and a third process starts at the third position (P3) after the predetermined time elapses from when the second process with respect to the first mold unit (800A) starts at the second position (P2), and a third time until the first mold unit (800A) moves in the third section (1703) and the first process starts at the first position (P1) after the predetermined time elapses from when the third process with respect to the first mold unit (800A) starts at the third position (P3).
