PURPOSE:To enable to cut a gate of a sealing member well and to improve the waterproofness by a method wherein in a method to attach a sealing member to a resin stock whose gate part is cut while being supported at the near position or at the gate part. CONSTITUTION:A resin member 18 is formed by injecting resin from an injection hole 21 at the revolution position where resin member forming cavity parts 16, 12 of a top force 11 and a bottom force 9 are alignmented, and after forming the member 18 is moved to part B by making the top force 11 rise and the bottom force 9 half revolutes, and the sealing member 35 is formed by injecting rubbery material through a runner 31 and the gate 30 with the top force 11 being descended again. And next, the gate part 35a of the sealing member is cut with a cut pin 27 is ascended by the elastic force of a spring 29 by the ascending of an elevating pin 33. Accordingly, the cutting position becomes stable and defective cutting will be prevented, because the gate part 35a will not extends. Thus, the setting can be carried out with high sealing effect. |
