2. Description of the Related Art In blow molding in which a hollow resin product is made from a parison that is cylindrically injected or extruded from a die head, the parison is injected or extruded from the dice head and pre-blown into a bag-shaped parison by a parison pinch. Then, inflate it slightly, put it in the open mold and close the mold, and remove the air remaining between the mold and the parison from the small air vent hole that communicates with the mold surface through the vacuum pump device. After suction, high-pressure air is blown into the parison to form the parison into a predetermined shape based on the cavity and then cooled by a mold to complete the molding.
In this way, the molded resin product is taken out by opening the mold. FIG. 8 shows a conventional blow molding machine. In FIG. 8, the molten resin is applied to the side 1 of the die head 2.
Shown is a so-called side-feed type blow molding machine 1 that is supplied from a location, in which a high-temperature molten resin pressed by an extruder 4 is provided between a die head 2 and a mandrel 3 via a resin supply port 2a. And the parison P is formed by being discharged from the lowermost annular space passage 7. The core 3a is connected to the paricon rod 6a penetrating the mandrel 3 and is slightly moved up and down in the vertical direction by the operation of the paricon cylinder 6 to control the wall thickness of the parison P (gap). ) Can be adjusted. On the other hand, as shown in FIG. 9, a resin is molded into a panel shape having a bag-shaped air space inside, for example, a door (gate) or a simple wall material (partition wall).
It has come to be considered to use it for building materials such as, and to use it for floors such as formwork for concrete pouring and simple piers, but these molded products have considerable structural strength despite their light weight. There is a feature that it is strong against deformation.

However, when a panel-shaped molded article having such a bag-shaped space inside is manufactured by blow molding, as shown in FIG. If you want to obtain a panel-shaped molded product with a rectangular parallelepiped shape that intersects at a right angle and does not have a curved portion at the corner, or if the radius of curvature of the curved portion is small, enclose the parison in an orthogonal mold. When molded, for example, as shown in FIG. 10, the corner portion (corner portion) becomes thin and the strength is reduced, or as shown in FIG. 11, a crack is generated due to a recess inside the parison of the corner portion. As a result, a satisfactory molded product cannot be obtained such that the defect of (3) is likely to occur. Therefore, it is unavoidable that the product has a draft θ as shown in FIG. 12 or the corners (corners R 1 , R 2 ) Is it advantageous to make the radius of curvature large? It was.

FIG. 3 is a side view of a panel-shaped molded product. As shown in Figure 1,
The blow molding machine 1 has the same die head 2 as the conventional structure,
The mandrel 3, the extruder 4, and the Parison cylinder 6 discharge a parison (preferably a flat parison) P between the pair of left and right dies 8, that is, the male die 8A and the female die 8B, and hang it down. The blow molding machine 1 of the present invention has a mold 8
Unlike the conventional structure, the male die 8A has a smooth flat surface.
And a female die 8B opposed to the female die 8B.
B is a main mold 8a having a smooth flat surface as shown in FIGS. 1 and 2, and is pin-joined to the four peripheral edges of the main mold 8a, and is rotationally driven by a motor 8M and rotatable about a rotation shaft 8N. It is formed from the auxiliary metal mold 8b. The auxiliary metal mold 8b rotates up to 90 degrees with respect to the main metal mold 8a, and when it reaches an orthogonal state of 90 degrees, the auxiliary metal molds 8b come into contact with each other and cannot rotate any more. . As shown in FIGS. 1 and 2, the main mold 8a and the auxiliary mold 8b are provided with a plurality of vent holes 8H in the peripheral portion thereof and are configured to be able to suck gas. Further, the mold opening and closing of both molds 8A and 8B are moved forward and backward by driving the mold clamping cylinders 9A and 9B. The operation of the blow molding machine 1 of the present invention having the pair of molds 8A and 8B thus configured will be described. First, the auxiliary mold 8b of the female mold 8B is opened (the contact surface of the parison P is almost vertical like the main mold 8a), and both molds 8A and 8B are opened. after,
The parison P is made to hang down and the molds 8A and 8B are clamped, and the auxiliary mold 8b is gradually rotated from the open state to the closed state. At the same time, the gas inside is suctioned by the vent holes 8H to bring the parison P into close contact with the corners (corners) formed by the main mold 8a and the auxiliary mold 8b. Then, after the auxiliary mold 8b reaches the closing limit (the position where the auxiliary mold 8b is orthogonal to the main mold 8a) and stands still, the blow pin (blowing pin) 10 is put into the parison P, and the compression part is set. Enclosed in the parison to further enhance the adhesion of the parison to the cavity surface. In this way, after the mold is clamped and kept for a certain cooling time, the parison P becomes a rectangular parallelepiped panel-shaped molded product formed by the main mold 8a, the auxiliary mold 8b and the male mold 8A. After the cooling time ends, the auxiliary mold 8b is opened, both molds 8A and 8B are retracted and opened, and the panel-shaped molded product 110 inside is taken out. 6 and 7 show the panel-shaped molded product 11 thus obtained.
