PURPOSE:To perform regulation easily and accurately, by combining a timer to a limit switch which regulates the width of cracking after the movement of a moving mold for closing mold is temporarily stopped. CONSTITUTION:After a moving cam 25 set up on a moving mold 22 push a limit switch 26, a timer 27 is worked and after a definite time preliminarily preset the movement of the moving mold 22 for closing mold is stopped, and thus setting a definite width of cracking between a fixed mold 21 and the moving mold 22. If the position of the moving cam 25 is once preset, the width W of cracking can be preset at arbitrary dimension only by changing the preset number of time in the timer 27. Thus there is such intricacies as previously must be done that an operator goes to the side of molding machine at every time and cuts an electric source and changes the position of the moving cam 25 from left to right, and regulation is made easily.
