PURPOSE:To facilitate exchange work of molds along with reliable performance of injection molding of synthetic resin, by arranging shaft centers of support pins provided on both of stationary and movable molds flush with each other highly accurately. CONSTITUTION:Two stationary side support pins 7, 7 stretched vertically from a stationary side base 3 are provided on two corner parts located on a diagonal line of the stationary side base 3. Two movable side support pins 22, 22 stretched vertically from a movable side base 18 are provided on two corner parts located on a diagonal line of the movable side base 18. Shaft centers of a stationary side support pin 7, movable side support pin 22 and guide pin 26 are flush with each other highly accurately, a stationary side connecting plate 13 and stationary side backing plate 14 are guided and moved by the pin 7 and a movable side connecting plate 29 and stripper plate 30 are guided and moved by the pins 22, 26 respectively. In case of exchanging of molds, a retainer plate 8 and the stationary side backing plate 14 are exchanged by removing a connecting bolt 11 and a bolt 15 and along with exchange of movable side backing plate 23 by removing the guide pin 26 from the movable support pin 22 the same is exchanged by removing a stripper plate 30 from a connecting rod 31.
