This blow molding apparatus is for molding a heat-resistant container. More specifically, an intermediate molded product as a first molded product is carried into a molding machine, and a heat-resistant container as a second molded product. It is molded and taken out.

In this blow molding machine, as shown in FIGS. 1 and 2, the upper end of a tie rod 12 erected on the molding machine base 10 is connected and fixed by an upper fixing plate 14, and below the upper fixing plate 14. The upper base 16 is slidably supported with respect to the tie rods 12, and the upper base 16 can be moved up and down by a drive cylinder 18 which is connected to the center of the lower surface of the upper base 16 and is a lifting drive means.

On the lower surface side of the upper base 16, a rotary plate 20 as a rotary transfer means is provided so as to be intermittently rotatable at a predetermined angle (120 degrees) by a rotary actuator 22 mounted on the upper base 16. .

Therefore, the rotary plate 20 is moved up and down as the upper base 16 is moved up and down, and is rotated on the lower surface of the upper base 16.

On the lower surface of the rotary plate 20, a neck-type support plate 2 composed of a split plate that supports the plurality of (four in this embodiment) neck dies 24, 24, which are split dies, so that they can be opened and closed.
6, 26 are arranged at three places with a distance of 120 degrees from the center, and a plurality of (four in this embodiment) molded products are supported with the neck portions supported by the plurality of neck molds 24, 24. For example, the container-shaped intermediate molded product 28 that is the first molded product, the intermediate molded product (not shown) after heat treatment, or the synthetic resin container 30 (see FIG. 2) that is the second molded product is the rotating plate 20. With intermittent rotation, it is driven intermittently at intervals of 120 degrees and can be stopped at three positions.

Further, processing stations such as a take-out station 32, a heat treatment station 34, and a blow molding station 36 are located at the stop positions along the rotation conveyance locus of the molded plate held by the neck molds 24, 24 by the rotary plate 20. It is arranged so that a heat-resistant container can be molded.

The take-out station 32 is also used as a receiving station, and the neck molds 24, 24 receive the intermediate molded product 28 blow-molded by another machine in advance.
Further, when the intermediate molded product 28 received by the neck molds 24, 24 is conveyed through the heat treatment station 34 and the blow molding station 36 and the synthetic resin container 30 is conveyed, the neck molds 24, 24 A container 30 made of synthetic resin is taken out to the outside, and a mold opening mechanism (not shown) for opening the neck mold supporting plates 26, 26 to open the neck molds 24, 24 is provided on the upper base 16.
