材(7)形状となる。Thus, the parison material (5) is placed between the pair of molds (8), and the parison material (5) is clamped by the mold (8) (FIG. 3(B)). At this time, parison material (
The lower part (5b) of 5) is a clamping device (5b) attached to the mold (8).
10). That is, parison material (5)
The lower part (5b) of the chuck plate (10) of the clamping device (10)
The opening is related to b). Parison material (5)
After the lower part (51+) of the parison material (5) is closed by the chuck plate (10b), air is injected from the upper part (5a) of the parison material (5) by the air injection device (9).
) is closed, the parison material (5) expands along the shape of the cavity (8a) of the mold (8) (FIG. 3(C)). After expanding the parison material (5) to a certain extent, while completely closing the mold (8), insert an air blowing bottle through the injection hole (8b) in the center of the mold (8), and Pierce the parison material (5) and inject air from the bottle into the parison material (5).
) is completely inflated, the parison material (5) will fit into the mold (8
) (FIG. 3(D)). The air injection bottle can be easily inserted into the parison material (5) because air is immediately injected into the parison material (5) by the air injection device (9) and has elasticity. Then, after cooling the parison material (5), the mold (8) is released (Fig. 3 (E)), and the parison material (5) takes the shape of the cavity (8a) of the mold (8). The skin member (7) of the headrest (6) follows the shape.

Insert an air blowing bottle into the parison material (5) through the injection hole (8b) of the mold (8), and
), this parison material (5) completely expands along the shape of the cavity (8a) of the mold (8), and the parison material (5) becomes the skin member of the headrest (6). (7) Once the parison material (5) is shaped and then cooled and released from the mold, the parison material (5) will become the skin member (7) of the headrest. In the piercing step 1, the parison material (5) is immediately injected with a certain amount of air by the air injection device (9) and has elasticity so that it does not move within the cavity (8a) of the mold (8).
The parison material (5) can be reliably expanded into the shape of the skin member (7) of the headrest.
