【発明の実施の形態】
以下、図面を参照しながら本発明について説明する。
図１は、本発明の１つの実施態様例を示している。
図１において、固定側金型パーツ４のキャビティ３に面する箇所に断熱ブロック層７が設けられている。この態様において、断熱ブロック層７は、キャビティ３に面する側の表層材料層８および金型パーツに接する側の金型パーツ隣接層（本明細書において、単に、隣接層とも称する。）９の２層を積層して形成されているが、この２層の間に１またはそれ以上の中間層を挟んだ形態として形成することもできる。従って、断熱ブロック層７は、少なくとも２種の層を積層して形成されている。[0016]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described with reference to the drawings.
FIG. 1 shows an example embodiment of the present invention.
In FIG. 1, a heat insulating block layer 7 is provided at a location facing the cavity 3 of the stationary mold part 4. In this embodiment, the heat insulating block layer 7 is the surface material layer 8 on the side facing the cavity 3 and the mold part adjacent layer on the side in contact with the mold part (herein also referred to simply as the adjacent layer) 9 . Although two layers are laminated, one or more intermediate layers may be sandwiched between the two layers. Therefore, the heat insulation block layer 7 is formed by laminating at least two types of layers.
