PURPOSE:To carry out fitting and combining a piece and a sleeve easily and with good accuracy by interposing a linear type guide bush between the sleeve and the piece and providing a clearance in the radial direction between an ejection rod of said piece and an ejector plate. CONSTITUTION:As an ejection rod 3 and a piece 2 of an injection mold 1 are corrected in the vertical direction to a sleeve 8 by a linear type guide bush 30 positioned on the inner side of the sleeve 8, ejection in the sleeve vertical direction is carried out all the time to the up and down operation of an ejector plate 13. Also, distortion generated by the correction by the linear type guide bush 30 is absorbed by the transfer of clearances 31 and 32 in the radial direction between the ejection rod 3 and the ejector plate 13, and a constant, vertical and smooth operation of the ejection rod 3 and the piece 2 to the sleeve 8 is carried out. |
