The mold profile 30 is arranged above the adjusting rod 21 and is in contact with one end of the adjusting rod 21. The contact point between the mold profile 30 and the one end of the adjusting rod 21 is always along the normal direction of the mold profile 30 and forms an adjustment surface on the upper surface of the mold profile 30.
