  • Publication number: 20190039278
    Abstract: A blow molding apparatus improves productivity and obtains a high-quality molded product by supplying a good-quality parison to molds. A blow molding apparatus includes: a die head which discharges a parison; a parison supplying part which cuts the discharged parison at a preset length and conveys the cut parison; and a blow molding part in which the supplied parison is clamped between blow molds so as to perform blow molding. The parison supplying part has a pickup chuck which conveys the cut parison alternately to a first supplying position set on one of right and left sides with respect to a discharge center of the die head and a second supplying position set on the other of right and left sides with respect to the discharge center. The blow molding part performs blow molding at the blow molds arranged at the first supplying position and the second supplying position, respectively.

  • Patent number: 9636865
    Abstract: A parison supply device that continuously supplies, to a blow molding die, parison sections of a parison discharged from an extrusion die, the parison section having a specified length. The parison supply device includes a plurality of tension chucks and a tension chuck operation unit that operates the plurality of tension chucks. The tension chuck operation unit causes the individual tension chucks to perform a repeated operation of grasping the parison at a first position near the extrusion die and moving to a second position separated from the extrusion die such that, before the preceding tension chuck is separated by a set distance from the extrusion die at the second position, the following tension chuck grasps the parison at the first position, and then the parison section is supplied to the blow molding die.

  • Patent number: 8652390
    Abstract: In supplying a predetermined amount of a molten resin D between an upper mold 10 and a lower mold 20 for compression molding, after the upper mold 10 is moved downward for a predetermined stroke length so that it approaches the lower mold 20 in which the molten resin D has been supplied, a compression load is applied while moving the lower mold 20 upward and supporting the upper mold 10 such that clamping is conducted against the compression load which has been applied to the lower mold 20. As a result, when molding a molded article in a predetermined shape by compression molding, if molds are allowed to open with a sufficient stroke length for taking a molded article out, prolongation of molding cycle can be effectively prevented, whereby a molded product in a predetermined shape can be mass-produced.

  • Patent number: 8168100
    Abstract: Each of supply means 30 arranged around an extrusion port 22 of an extruder 20 supplies, while cutting a molten resin which has been extruded from the extrusion port 22 of the extruder 20 alternately in a predetermined length, the molten resin D which has been cut to a supply position which is provided at each of the supply means, and then sequentially supplies the molten resin D to each of a compression molding dies 40 which are provided in a pair with each of the supply means. As a result, in producing a synthetic resin molded article with a predetermined shape by compression molding by cutting a molten resin which has been extruded from an extruder and supplying the resin which has been cut to a compression molding die, the above-mentioned constitution can be preferably utilized for the production of a synthetic resin molded product which requires a further high load.

  • Patent number: 7935300
    Abstract: A manufacturing method of a resin container includes continuously supplying a base material resin forming a container body from a main extruder, discharging from a discharge portion provided in a die head a sub-material supplied from a sub-extruder so that the sub-material joins the base material resin, extruding a parison from a slit portion opened on an end side of the die head, and blow-molding the parison, thereby forming a coating layer which covers the whole or a part of the container body by using the sub-material. A thickness reducing portion in which a thickness is continuously reduced is formed in the coating layer while adjusting a resin pressure in a supply path of the sub-material fed from the sub-extruder by performing suck-back control which pulls back the sub-material from the discharge portion at an arbitrary timing when joining the sub-material with the base material resin.
