[0022] In this embodiment, the material guide seat 5 is located inside the slide groove 7 and is set to slide back and forth. The feed hole 6 in the material guide seat 5 is on the same vertical line as the feed hole 6 in the upper mold 2. The injection liquid is added to the molding groove in the lower mold 1 through the feed hole 6, and the waste material in the feed hole 6 is cut off by the sliding of the material guide seat 5.
