Claims

[Claim for Utility Model Registration] When removing a mold that is vertically fixed to the support part via a dowel pin, the mold is inserted into the mold by engaging with a screw hole for a fixing bolt formed coaxially with the dowel pin in the mold. a hollow cylindrical shaft body that is inserted into the screw hole and has a male threaded portion formed on its outer periphery to be screwed into the screw hole;
It is equipped with an engaging pin that is inserted inside the shaft and whose tip engages with the tip of the shaft, and the shaft has a split groove that reaches the tip and opens, and the tip of the shaft. The inner surface of the shaft is provided with a tapered surface that increases in diameter toward the tip, and when the engagement pin is pushed down, the tip of the shaft expands to the outer periphery and the male thread of the shaft fits into the screw hole. A mold extraction jig characterized in that it is configured to engage with a screw.
