Assemble the upper and lower molds 2 and 1 using the mounting bolts 3. Thereafter, the injection cup 4 is similarly attached to the upper mold 2 with bolts 5. Next, the entire molds 1 and 2 assembled to the stator are placed in a vacuum tank (not shown), and after maintaining the atmospheric pressure in the range of 1 to 3 mHf, the molds 1 and 2 assembled to the stator are placed in a vacuum tank (not shown), and then a material such as pulp is inserted from outside the vacuum tank. Insulating synthetic resin is supplied to the injection port cup 4. The supplied synthetic resin is impregnated into the coil 8 from the synthetic resin inlet groove 6, but at this time, since it is in a vacuum state, the air inside the coil 8 is discharged, and the synthetic resin impregnated into the coil 8 is bubbled. Mixing is prevented.

。An embodiment of the present invention will be described below with reference to the drawings. 1st
In FIGS. 2 to 4, the same or equivalent parts as in the figures are indicated by the same reference numerals, 11 is a positioning bin, 12 is a second
As shown in FIG. 3, the ears la of the upper and lower molds 2, 1
The upper and lower mold mounting jigs are attached to the upper and lower molds 2a, and are made of a material having a coefficient of thermal expansion larger than that of the upper and lower molds 2 and 1. For example, when the upper and lower molds 2, 1 are made of metal such as iron, plastics with a higher coefficient of thermal expansion are used, and the upper and lower molds 2, 1 are made of metal through the head 13a of the fixing piece 130 by preheating. It is designed to exert a tightening force that prevents the synthetic resin from leaking when tightened. 14 is a cup fixing piece provided integrally with the upper mold 2, as shown in FIGS. The inserted cup fixing jig is made of a material having a coefficient of thermal expansion larger than that of the upper mold 2 and the cup fixing piece 14.
そして、予熱を加えることによって、注入口カップ4を
カップ固定片14に固着締付けるように形成されている
。By applying preheating, the inlet cup 4 is fixedly fastened to the cup fixing piece 14.
次にこの発明の動作について説明する。Next, the operation of this invention will be explained.

組付ける。First, after aligning the positioning pins 11, the upper and lower mold mounting jigs 12, which have a higher coefficient of thermal expansion than the upper and lower molds 2#1, are engaged with the ears 1a e 2a, as shown in FIG. A cup fixing jig 15 having a large coefficient of thermal expansion is also inserted into the inlet cup 4 as shown in the fourth figure. After that, preheating is usually applied to improve the flow of the synthetic resin. Due to this preheating, the upper and lower mold jigs 12 undergo large thermal expansion, and the upper and lower mold jigs 2,
1. Tighten them together and assemble them so that the synthetic resin does not leak between them.
注入口カップ4もカップ固定治具15によって同様に取
シ付けられる。The inlet cup 4 is similarly attached using a cup fixing jig 15.
その後、従来と同様に真空タンク内および加熱炉に入れ
られ、合成樹脂が硬化され、コイル8等の絶縁作業が終
了する。Thereafter, as in the conventional case, it is placed in a vacuum tank and a heating furnace, the synthetic resin is cured, and the insulation work of the coil 8 and the like is completed.

自動的に解体できる。After insulating the coil 8 and other predetermined parts using synthetic resin, if the entire molds 1 and 2 are cooled, the upper and lower mold mounting jigs 12 and the cup mounting jigs 15 will return to their original shapes and dimensions. When returned, the upper and lower molds 2°1 and the inlet cup 4 can be automatically dismantled.
また、上記実施例では固定子の絶縁の場合について説明
したが、その他一般の電気部品の絶縁についても適用で
き、上記実施例と同様の効果を奏する。Furthermore, although the above embodiment describes the case of insulating a stator, it can also be applied to insulating other general electric components, and the same effects as in the above embodiment can be achieved.
