Next, a thermoplastic resin can be injected into the tank portion forming space formed in the molding die to form a tank portion made of the thermoplastic resin, which can be integrated with the sealing portion formed previously.
以下、本発明を図面に従って詳細に説明する。 Hereinafter, the present invention will be described in detail with reference to the drawings.
第１図及び第２図は本発明の一実施例に係る樹脂製タン
クの製造方法を示すものである。1 and 2 show a method of manufacturing a resin tank according to an embodiment of the present invention.
先ず、第１図（Ａ）及び第２図の第１ステーション11に

用空間内に、下側の成形金型15に設けた射出ノズル16か
ら適宜のゴム，熱可塑性樹脂等の熱可塑性でかつ弾性を
有する材料から成るシーリング材を注入して、シーリン
グ部３を形成する。First, as shown in the first station 11 of FIG. 1 (A) and FIG. 2, two molding dies 14 and 15 are set to form a space for forming a sealing portion. A sealing material made of a material having thermoplasticity and elasticity such as appropriate rubber or thermoplastic resin is injected into the space for forming the sealing portion from an injection nozzle 16 provided in a lower molding die 15 to perform sealing. Form part 3.
尚、該シーリング部３はタンク部２に比べ硬度の低い材
質のものが使用され、材料の硬度範囲は45度〜90度であ
るが、その好適な硬度は60度〜80度である。The sealing portion 3 is made of a material having a hardness lower than that of the tank portion 2. The hardness range of the material is 45 to 90 degrees, and the preferable hardness is 60 to 80 degrees.
次に、上側の成形金型14を取り外し、シーリング部３を
形成した下側の成形金型15を、第１図（Ｂ）及び第２図
の第２ステーション12に移動する。Next, the upper molding die 14 is removed, and the lower molding die 15 on which the sealing portion 3 is formed is moved to the second station 12 shown in FIGS. 1 (B) and 2.
そして、第２ステーション12において、下側の成形金型
15上に、タンク部形成空間を成形する別の上側の成形金
型17をセットする。Then, in the second station 12, the lower molding die
Another upper molding die 17 for molding the tank portion forming space is set on 15.
その後、上側の成形金型17に設けた射出ノズル18から、
例えば、ガラス繊維を混在させたナイロン樹脂等、適宜
の熱可塑性樹脂を注入して、タンク部２を形成する。After that, from the injection nozzle 18 provided in the upper molding die 17,
For example, the tank portion 2 is formed by injecting an appropriate thermoplastic resin such as nylon resin mixed with glass fibers.
その後、上側の成形金型17を取り外し、シーリンク部３
とタンク部２とを形成した下側の成形金型15を、第１図
（Ｃ）及び第２図の第３ステーション13に移動し、完成
品の取出を行う。After that, the upper molding die 17 is removed, and the sea link part 3
The lower molding die 15 on which the tank 2 and the tank 2 are formed is moved to the third station 13 shown in FIGS. 1 (C) and 2, and the finished product is taken out.
以上のように、本実施例によれば、シーリング部３を先
に形成した後にタンク部２を形成するので、シーリング
部３とタンク部２とを一体化することが可能となる。As described above, according to this embodiment, since the sealing portion 3 is first formed and then the tank portion 2 is formed, the sealing portion 3 and the tank portion 2 can be integrated.
特に、上記工程の第２ステーション12において、先に形
成されたシーリング部３とタンク部２との境界部では、
熱可塑性樹脂の射出圧が高いので、シーリング部３は、
第３図に示すように、矢印の方向に逃げる力が加わり、
タンク部２とシーリング部３との剥離の発生を防止する
ことができる。In particular, in the second station 12 of the above process, at the boundary between the previously formed sealing part 3 and the tank part 2,
Since the injection pressure of the thermoplastic resin is high, the sealing part 3
As shown in Fig. 3, a force to escape is added in the direction of the arrow,
It is possible to prevent the occurrence of peeling between the tank portion 2 and the sealing portion 3.
又、タンク部２とシーリング部３との接合部をアンダー
カットとした場合、シーリング部３を先に成形しても、
シーリング部３が弾力性を有するので、上側の形成金型
14を無理抜きしても、製品形状を確保することができ
る。Further, when the joint between the tank portion 2 and the sealing portion 3 is undercut, even if the sealing portion 3 is molded first,
Since the sealing part 3 has elasticity, the molding die on the upper side
The product shape can be secured even if 14 is forcibly removed.
従って、第４図に示すように、タンク部２のシーリング
部３との接合部が楔状となり、タンク部２とシーリング
部３とを抜け難くすることが可能となる。Therefore, as shown in FIG. 4, the joint portion of the tank portion 2 with the sealing portion 3 has a wedge shape, and it is possible to make it difficult to pull out the tank portion 2 and the sealing portion 3.
第５図は、タンク部２とシーリング部３との接着性を良
くするため、両者の接着面をそれぞれギザ面５にしたも
のである。In FIG. 5, in order to improve the adhesiveness between the tank portion 2 and the sealing portion 3, the adhesive surfaces of the two are made to be serrated surfaces 5, respectively.
尚、以上の実施例では樹脂製タンク１に座板19を取り付

ックやサーモスイッチを取り付ける場合等、密封係合を
必要とされるあらゆる個所に適用できることは言うまで
もない。In the above embodiments, the case where the seat plate 19 is attached to the resin tank 1 has been described, but in addition, when the drain cock or the thermo switch is attached to the resin tank, it is necessary to attach the seal plate to any place where sealing engagement is required. It goes without saying that it can be applied.

とができる。As described above, according to the method of manufacturing a resin tank of the present invention, a sealing material made of a material which is thermoplastic and has elasticity is injected in advance to form a sealing portion, which is then formed in a molding die. Since the thermoplastic resin is injected into the tank portion forming space to form the tank portion made of the thermoplastic resin, the sealing portion and the tank portion can be integrally formed.

に比べ低くできる等の利点がある。In addition, since the sealing part is first formed and then the tank part is formed, the displacement of the sealing member is completely eliminated and the compressibility of the sealing member is made uniform, so that the sealing property is improved and liquid leakage is prevented. In addition, since the sealing surface of the tank is formed of an elastic body, there is an advantage that the precision of the mold at the time of manufacturing can be made lower than in the conventional case.
