雑な形状を有する、非中空部のある中空合成樹脂
成形品の成形法ならびに成形装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a molding method and a molding apparatus for hollow synthetic resin molded articles having a non-hollow portion and having a complicated shape, such as a collector portion of a solar water heater.

〔従来の技術〕[Conventional technology]

果的なものに至つておらず、種々問題がある。 Traditionally, blow molding and vacuum molding have been used as methods for molding hollow synthetic resin molded products with non-hollow parts that have complex shapes, but neither method has been effective and there are various problems. There is.

空間内で割金型を型閉じすることが必要となり、
このため金型装置が複雑となる。 In other words, in the case of blow molding, when the split mold is closed, the parison is pushed by the part of the mold that corresponds to the non-hollow part of the target molded product, so the surrounding part of the parison bulges out of the mold due to air pressure, causing the flesh of that part to bulge out. The thickness inevitably decreases, and as a result, it becomes impossible to mold the hollow part around the target molded product, or the thickness becomes so thin that it cannot be put to practical use.
To avoid this, it is necessary to first seal off the area around the split mold under the opening of the mold by some means, and then close the split mold within the sealed space.
This makes the mold device complicated.

また真空成形の場合、可塑化シート状物及びパ
リソンを用いることになるが、非中空部の合体が
不充分となるおそれがある。 In addition, in the case of vacuum forming, a plasticized sheet-like material and a parison are used, but there is a risk that the non-hollow portions may not be sufficiently integrated.

It is an object of the present invention to provide a molding method and a molding apparatus that can reliably mold a hollow synthetic resin molded product having a non-hollow portion.

形装置である。 That is, the first aspect of the present invention is to hang a parison or two parallel sheets of plasticized material (hereinafter referred to as parisons) in the space facing the split mold, and while closing the mold, the peripheral edge of the split mold is suspended. Negative pressure is applied to the many vacuum suction holes provided on the parting surface and the molding cavity, and these parisons are attracted to the uneven parts of the parting surface, and then to the molding cavity and the mold is clamped. The second aspect of the present invention is a method for molding a hollow synthetic resin molded product having a non-hollow part, in which a part of the molded body components are combined with each other to form a non-hollow part, and finished by blowing air. It has a non-hollow part consisting of an extruder, a mold clamping device with a large number of vacuum suction holes in the peripheral parting line surface of the split mold and the molding cavity, and a mold clamping device equipped with a nozzle for blowing air into the raw molded body. This is a molding device for hollow synthetic resin molded products.

Since a vacuum suction hole is provided surrounding the molding cavity, the part of the parison around the molding cavity of the split mold is sealed prior to the vacuum adsorption molding of the parison into the molding cavity, and the parison is removed from the mold by blow molding. Vacuum forming and hollow forming of the parison can be smoothly performed without bulging outward.

連結される。 The split mold 1 has a vacuum suction hole 4 in the molding cavity 2.
is installed, and a split mold 1 is installed on the parting line 3.
A vacuum suction hole 5 is provided surrounding the molding cavity 2. The vacuum suction holes 4 are arranged at appropriate intervals in the length direction of the hollow portion c, and the vacuum suction holes 5 are arranged at appropriate intervals along the parting line 3. These vacuum suction holes 4 and 5 communicate with each other through a through hole 6 formed in the split mold 1, and the through hole 6 is connected to a vacuum pump (not shown).

とにより、補助できる。 The split mold 1 is brought close to the parison 7, and vacuum pressure is applied to the vacuum suction holes 4 and 5 through the through hole 6. Thus,
The parison 7 is first attracted to a portion of the split mold 1 corresponding to the parting line 3, and then, as a result, the molding cavity 2 of the split mold 1 is sealed by the suction of the parison 7. (See Figure 6). This sealing can be achieved by raising the heated compressed air blower 9 to a predetermined height if the parison 7 has a downwardly open shape, and when the parison is adsorbed to the parting line 3 by vacuum through the holes 5. This can be assisted by blowing heated compressed air onto the parison from the outlet of the blower.

る。 At this time, air is blown into the hollow part c of the molded product A in the split mold 1, and thus a hollow molded product A having a predetermined shape is obtained (see FIG. 8). This air blowing may be performed using a syringe needle type air blowing tube 10. The air blowing pipe 10 is provided in the split mold 1 and can move forward and backward on the split mold 1. During vacuum forming of the parison 7, the needle pipe 11 is retracted to a position where it does not protrude into the molding cavity 2, and when air is blown The needle tube 11 is advanced and pierced into the hollow part c of the molded product.

割金型１から成形品Ａを取外すには常法に従え

A parison or two parallel plasticized sheets are suspended in the opposing space of the split mold, and while the mold is closed, a large number of plasticized sheets provided on the peripheral parting surface of the split mold and the molding cavity are suspended. Activate the vacuum suction hole of
While applying negative pressure, these plasticized materials are adsorbed to the parting surface, and then to the molding cavity, and the molds are clamped. Part of the molded product components on each mold side are combined with each other to form a non-hollow part. A method for molding a hollow synthetic resin molded product having a non-hollow part, which is finished by blowing air. 2. An extruder that hangs a parison or two parallel plasticized sheets, and a large number of vacuum suction holes in the peripheral parting line surface of the split mold and in the molding cavity to blow air into the raw molded product. A molding device for hollow synthetic resin molded products having a non-hollow part, consisting of a mold clamping device equipped with a nozzle.
