In the present invention, a laser pointer is mounted on an upper mold and formed to mark a position of an auxiliary raw material disposed on a raw material disposed on a lower mold so that everyone can easily accurately arrange the auxiliary raw material at a predetermined position and molds the auxiliary raw material to improve a molding efficiency. In particular, in the present invention, the laser pointer is formed to mark vertex positions of the auxiliary raw material so that an operator can arrange vertexes of the auxiliary raw material at the predetermined position to quickly arrange the auxiliary raw material at the predetermined position and accurately mold the auxiliary raw material. In this case, in the present invention, at least two laser points are mounted along an edge of the upper mold to mark vertices of the auxiliary raw material so that the auxiliary raw material can be more quickly accurately disposed at the predetermined position and integrally molded.
