硬化性樹脂に対しては吹込成形手段は適用できない。(Prior art) Conventional synthetic resin bottle-shaped containers are usually manufactured using simple blow molding method,
Various blow molding methods are used depending on factors such as the properties of the resin used and the shape of the desired molded product, such as injection blow molding, cold parison, sheet parison, and stretch blow molding. Examples of resin types include polyethylene, polypropylene, polystyrene,
It is limited to materials with relatively low melting points, such as polyvinyl chloride, ABS, polycarbonate, and polyamide, and is limited to polyethylene terephthalate (melting point: 256° C.). Therefore, the usable temperature is 20, which is generally called heat-resistant resin.
Resins at 0°C or higher, such as fluororesins, aromatic polyamides,
Blow molding means cannot be applied to high melting point or high temperature curable resins such as aromatic polyester, polyether sulfone, silicone resin, polyamideimide, polyimide, thermosetting polybutadiene or heat resistant epoxy resin.

ニーリングは屡々行われることであるが、本操作は通常
全体の機械的性質を低下させる。Therefore, in order to manufacture bottle-shaped containers that require heat resistance, conventional containers have been manufactured by doubling the container vertically with the shoulder as a boundary, injection molding, and then heat welding both parts. However, according to such a method, in addition to being troublesome to operate, a seam line is inevitably generated at the joint, and this seam line significantly weakens the overall pressure resistance strength. In addition, because the bonding process locally heats up to high temperatures, resin decomposition and residual stress tend to deteriorate the quality of the product. Incidentally, annealing is often performed to remove residual stress. However, this operation usually reduces the overall mechanical properties.

特徴とする。(Means for Achieving the Object) In order to achieve the above object, the method for manufacturing a #heat and pressure resistant container made of synthetic resin according to the present invention includes an engraved body constructed inside a cavity having an inner shape of a bottle-shaped body. After inserting and fixing a thin-walled hollow inner mold (core) having an outer shape corresponding to the inner shape of the molded object with a gap equal to the wall thickness of the molded object, pressurized fluid pressure is applied into the inner mold. Injecting high melting point resin into the gap while acting,
After curing, the inner mold is pulled out and removed from the object to be molded.

The two sections unite at a position slightly below the shoulder of the container to be molded to form a complete outer mold (see Figure 1), and the inner mold (

る。As will be explained later, while the main mold can withstand high temperatures during resin injection, it must be removed from the mouth of the molded container by pulling after molding is completed.For this reason, the material of the main mold is In addition to being heat resistant to the resin temperature at the time of implantation, it must also have enough plasticity to be deformable during removal.Specifically, soft gold materials such as aluminum, copper, and magnesium are exemplified. , aluminum, and copper are particularly suitable for this purpose because they are easily annealed by the heat received during injection of the resin material. Note that the mouth of the inner mold forms a handle part (2) that enters into the outer mold. Further, the wall thickness of one inner mold is preferably as thin as possible as long as there is no problem in manufacturing and handling, but it is usually necessary to have a thickness of 0.5+sm or more.

を兼ねるので最も好ましい。The inner mold described above needs to be reliably held within the outer mold with a certain gap between it and the inner wall of the chain wheel. At the same time, it must not be deformed, crushed or vibrated due to the enormous pressure generated during resin injection, so the wooden mold must be
For example, it is supported by a pipe Q having approximately the same diameter as the inner diameter of its mouth, and is counteracted by the pressurized fluid pressure applied to the inner wall of the inner mold through a small hole bored in the pipe. Any fluid may be used for this purpose, but water is most preferred since it also serves as a refrigerant.
第３図〜第６図は、上記第１図の外型と第２図の内型と

５０ ｋｇ／ｃｍ２程度の高温、高圧が必要である。Next, the molten resin material enters the cavity (3°) between the outer mold and the inner mold through the gate at the bottom of the lb.
At the same time, the small hole (6, 6, -
・) High-pressure cold water (W) is introduced into the inner mold (injection process; Fig. 4). At this time, the inner mold is preferably preheated to about 200°C, or If the temperature is lower than this temperature, the resin will not adhere tightly to the inner mold. Therefore, before introducing cold water, a heat medium (for example, hot air) is blown into 2 through the small hole 2 of the pipe 2 to preheat the chain wheel. However, if desired, the inner mold (2) may be preheated with flame before mold clamping instead of introducing a heat medium.
High temperature and pressure of about 50 kg/cm2 are required.

After contracting and deforming the chain wheel, take out the semi-finished container (C) filled with the inner mold (C).

ィングラインを生じ難いという特色がある。Finally, the handle part ■ of the deformed inner mold ■ in the container to be molded (C) which has been taken out is pulled out from inside C to obtain a completed container (Co) (finishing process: Fig. 6). The shape of the container can be freely deformed within the so-called plate shape, and if desired, it can be made into a spherical shape to provide maximum pressure resistance. Product container (Co) in the example in the previous six figures
is a standard box-shaped container with a two-lunge CC" f), but the container obtained with the mold shown in Fig. 7 is a screw type container. In this example, the outer mold ■ is a container to be molded. Since the product container is divided at the boundary between the bottom and the body, it has the feature that it is difficult to form parting lines on the product container.
