時間が多くかかり、ロス時間を費やすことになる。(Problems to be Solved by the Invention) In the mold thickness adjustment performed using the male and female screws for mold thickness adjustment described above, the threaded portion receives the mold clamping force, so the strength of the threaded portion becomes a problem. When the mold clamping force becomes particularly large, the diameter of the screw needs to be extremely thick, which increases the cost of manufacturing the parts. Furthermore, when the range of mold thickness adjustment becomes thick, it takes a lot of time to adjust the mold thickness, resulting in wasted time.
