る。In place of the general-purpose machine, there has recently been an invention of a dedicated machine for producing hollow molded products such as the bent pipes and ducts without burrs. One example thereof is Japanese Patent Laid-Open No. 55-21239, which discloses an extruder. Two lower dies to be transferred between the die head and the mold clamping device are installed on the turntable, and these die heads are set in the X, Y, and Z axis directions with respect to the lower die set at the parison extrusion position. Although a manufacturing device equipped to move back and forth, left and right, and up and down by driving control of a motor for moving is disclosed and disclosed, in this manufacturing device, it is possible to drive the turntable of the lower mold and move the die head. In addition to requiring a large driving force, the moving mechanism complicates and enlarges the entire manufacturing apparatus, and the molten parison extruded from the die head downward nozzle for parison extrusion is engraved in two or three dimensions of the lower die. In order to be accepted by copying in the cavity, the die head movement control program must be highly accurate, and this movement mechanism is required for each lower die, making the manufacturing equipment large and expensive.

I have a feeling that I'm one step closer.

チック製の中空成形品を所定肉厚で中空成形できる。In addition to the effects of the specific invention, in the device according to claim 3, the parison is a cylindrical softened parison separated from the downward nozzle, and the lower mold has a first position for receiving the parison from the robot. Since it is arranged so that it can be horizontally reciprocated between the upper mold and a second position where it overlaps, the robot hand and the upper mold are prevented from interfering with each other, and the parison cut and separated from the nozzle is separated. The cavity of the lower mold can be imitated, and the temperature of the parison can be adjusted in the lower mold regardless of the temperature of the downward nozzle, and the hollow molded article made of engineering plastic can be made to have a predetermined wall thickness. Can be blow molded.
