Description of the invention (2) The molds 3'2 can be clamped respectively. Also, the lock plate 2 4 corresponds to the injection heart shape (core) of the injection molding section 12 3 6 is provided with a blowing heart shape 3 8 corresponding to the extended blow forming portion 14. Since the lock mold cylinder 40 provided on the support plate 20 is used to lower the lock plate 2 4, the heart shape 3 6 will be ejected. And blown heart shape 3 8 and each neck mold 2 8 can lock the injection mold hole mold 30 and the blow mold hole mold 3 2 respectively. Press to lock the mold plate 2 at the position corresponding to the extended blow molding portion 1 4 4 'is provided with an extension rod lifting and lowering cylinder 4 4 which moves the extension rod 4 2 forward and backward. In this injection extension blow molding device, the heart shape 3 6 will be injected. The clamping drive of the 38 and the neck mold 28 will be performed on the clamping cylinder 40 of the support plate 20 provided above the clamping plate 24. Therefore, the clamping force of the clamping cylinder 40 must be increased. Moving the lock plate 24 from the position directly below the support plate 20 to the vicinity of the injection mold hole mold 30 and the blow mold hole mold 32 requires a large moving stroke. Therefore, the size of the lock cylinder 40 is large and the weight is large. It becomes larger, and the length of the cylinder becomes longer, so that the total height of the device becomes higher. As such, because the weight is located at the highest position, the balance as a blow molding machine is very poor and unstable. Furthermore, the upper base plate 22 is raised and lowered. Since the lifting cylinder 34 is located approximately at the center of the lower base plate 16, the lifting cylinder 34 becomes an obstacle and cannot take a large blow stroke for blow mold clamping, and maintenance operations also become difficult.

With this configuration, since the cylinder fixing plate is raised and lowered integrally with the upper base plate, the distance between the cylinder fixing plate and the upper base plate is kept constant. Therefore, the stroke of the injection heart-shaped clamping cylinder is suppressed to a minimum, and miniaturization of the injection heart-shaped clamping cylinder can be achieved. In addition, since it has an injection heart-shaped mold clamping cylinder, the mold clamping device in the machine can be used as a mold clamping device exclusively for a neck mold. Therefore, by dispersing the functions of the mold clamping device and the injection heart-shaped mold clamping cylinder separately, each mold clamping portion can be made lighter. In one aspect of the present invention, the mold clamping device may be disposed below the injection molding section. With this structure, other forming parts that are more blow-molded (please read the precautions on the back before filling this page) This paper size applies to China National Standard (CNS) A4 (210X297 mm) 490385 A7 B7 V.

As a result, the mold 1 is ejected into the heart mold 1 2 and the neck mold 9 0, and the molten resin is ejected from the injection device 6 4 into the injection mold hole mold 8. The preform 1 2 4 can be injected. At this time, the injection heart-shaped clamping cylinder 1 1 6 is lowered integrally as the upper base plate 5 6 is lowered. Therefore, the distance between the injection heart-shaped clamping cylinder 1 16 and the upper base plate 56 is always kept constant. Therefore, the lowering stroke L 2 of the injection heart-shaped mold clamping cylinder 1 1 6 is only the minimum stroke required to open and close the injection heart-shaped mold cylinder 1 1 2, so the length of the injection heart-shaped mold clamping cylinder 1 1 6 can be shortened. . In addition, the injection heart-shaped mold clamping cylinder 1 1 6 series is sufficient as long as the mold clamping force of the injection heart-shaped mold mold 1 12 is obtained, so the injection heart-shaped mold compression cylinder 116 can be made smaller. Therefore, the total height of the injection stretch blow molding device 50 can be suppressed low, and the weight on the upper side can be suppressed from becoming well balanced, while the injection stretch blow molding device 50 can be kept stable. In addition, the neck mold clamping cylinder 1 2 0 is sufficient as long as it has a clamping force that matches the clamping lever force of the neck mold 90, and can be made smaller. In addition, since the neck mold clamping cylinder 120 is disposed below the injection molding portion 6 8, even if the neck mold clamping cylinder 120 is smaller, the clamping force can be effectively utilized.
