Claims

[Scope of utility model registration request]

A tieper with threaded portions formed on both ends is inserted between a fixed plate of an injection molding crosspiece, mold clamping cylinder, etc., one end is screwed with a tie bar nut, and the other end is split into two along a dividing line passing through the axis of the tieper. In a mold clamping device such as an injection molding machine that tightens between the fixed plate and a mold clamping cylinder by screwing together a split nut, the nut rotating mechanism tightens and loosens the split nut; A nut engagement mechanism that opens and closes the split nut from a direction perpendicular to the axis and engages and disengages the tie bar threaded portion with the split nut threaded portion; regulates the length of the tie bar inserted into the fixing plate or mold clamping cylinder, etc. A split collar provided on the split nut side of the tie bar; a split collar provided on the movable plate; when the split nut is disengaged from the threaded part, the movable plate moves the tie bar in a predetermined moving direction by forward and backward movement of the movable plate; A tie-harlock mechanism 1 for locking the tie bar; provided on a fixing plate or mold clamping cylinder, etc. at the opposite end of the split nut of the tie bar, and locking the tie bar with the fixing plate or mold clamping cylinder, etc. during the removal or insertion work of the tie bar; However, a mold clamping device for an injection molding machine or the like comprises a tie bar lock mechanism 2 which is configured such that the tie bar lock mechanism 2 is not locked while the tie bar is locked by the tie bar lock mechanism 1.
