本発明は内部にインサートを有する中空成形品の成形方

者達はこの課題にこたえるべく種々検討し本発明に到達
した。However, in the development of thermoplastic resin fuel tanks, for example, thermoplastic resin fuel tanks are required to have the same functions as metal fuel tanks. The market situation is such that there is a demand for the development of hollow molded products with even higher added value, such as by providing an inner tank in which the liquid content is always present. The inventors of the present invention conducted various studies to solve this problem and arrived at the present invention.

る。That is, the gist of the present invention is to close the mold while leaving the insert part held by the village body inside the molten thermoplastic resin parison, brie-blow the molten thermoplastic resin parison, and then release the body inside the parison. This is a method for molding a medium-molded product with an insert, characterized in that after the insert part gripped by the insert part is crimped onto the inner wall surface of the parison, air is blown thereinto. Examples of the present invention will be described below with reference to the drawings.

より固着させ易い。FIG. 1A is a vertical cross-sectional view showing a part of the process of the present invention.
The mold 4 is closed and the pre-blowing is carried out while the inner tank, that is, the insert part 3 held by the village body 2 is present inside the mold 4.
Immediately after this, the insert part 3 held by the bar body 2 is moved laterally by the actuating mechanism provided in the bar body 2 to press it against the inner wall surface of the parison, and the air blowing pin (
(not shown). However, the air blowing pin may be provided other than the punch body. Note that if the above-mentioned pre-explosion is not performed, the insert part 3 will be fused during the air injection after the insert part is crimped to the inner wall surface of the parison, making it difficult to uniformly expand the parison, resulting in a hollow molded product. This can easily lead to uneven thickness. The vertical cross-sectional view of the obtained hollow molded product is shown in Figure lb, and the perspective view of the inner tank, that is, the insert part 3 is shown in Figure lc.The material of the insert part may be thermoplastic resin, metal, etc. The same type of thermoplastic resin can be easily fixed by pressure bonding.
さらに本発明によれば、内部に防波板、仕切板などのイ
ンサートを有する中空形成品を得ることもできる。Furthermore, according to the present invention, it is also possible to obtain a hollow molded product having inserts such as a wave-proof plate and a partition plate inside.
