下にこの発明の一実施例を添付図面に基づいて詳細に説
明する。Therefore, tanks that are divided into multiple parts are widely used, and the structure is such that, for example, a stainless steel partition plate is welded into the stainless steel tank body, which poses problems such as poor workability and high cost. Ta. On the other hand, synthetic resin tanks have been developed to reduce the weight of tanks.
This synthetic resin tank also had the disadvantage that the tank body and the partition part had to be processed separately. This invention was made in view of the above circumstances, and its gist is that the tank body and the partition are made of synthetic resin, and are integrally molded at the same time, making manufacturing easier. The purpose of the present invention is to provide a method for forming a multi-tank tank, which is characterized by being able to manufacture a lightweight and inexpensive tank. An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

Reference numerals 1 and 1 denote molds that are divided into two parts to form the main body of the turnk, and between the mold mating surfaces 1a and 1a of these molds 1 and 1, a thin metal wire 2 such as a wire is used for partitioning metal. The plate 3 is suspended in the air, and both molds 1, 1 are supported rotatably about the longitudinal axis of the tank (not shown).

A through hole 3a is bored in the center to actively eliminate the internal pressure difference between the two chambers 4, 4. Mold 1 formed as above,
1 by heating the outside of the mold 1 with a heating means 5 such as a burner to sufficiently heat the entire mold 1, 1 and the metal plate 3. Pail-shaped synthetic resin material 1 is introduced from 6 and 6, and the mold 1.1
By rotating the synthetic resin material T, the synthetic resin material T comes into contact with the surface of the metal plate 3, and is welded in a layered manner to the inner surface of the mold 111 by the centrifugal force of the rotating molds 1, 1.
As shown in the figure, it also flows into the gap between the metal plate 3 and the mold 1, forming a two-tank tank with independently separated chambers 4, 4. Note that the metal wire 2 is made of synthetic resin material r.
buried within. Although the above embodiment describes the method for forming a two-tank tank, in this invention, the internal pressure difference between the two chambers 4, 4 divided by the metal plate 3 is Since it is designed to take the average of 3
The same applies to the case of a tank or larger, and in these cases, a partitioning metal plate is placed in a suspended manner between the respective mold mating surfaces of the split molds forming the tank body, and then the same process is carried out. A multi-vessel tank can be formed by

とができるので、その利用価値は顕著である。As explained above, according to the molding method of the present invention,
The tank body and partition can be made of synthetic resin, and the tank body and partition can be integrally molded at the same time, making it significantly cheaper to manufacture than conventional stainless steel welded tanks. In addition, it is possible to reduce the labor and time in manufacturing, and also to manufacture a lightweight and robust tank, so its utility value is remarkable.
