2. Description of the Related Art Conventionally, as a method of manufacturing a motor housing member having such insert fittings, a housing molded product having a fitting portion for fitting the insert fittings is formed, and then the insert fittings are formed as post-processing. After inserting and soldering, the lead wire is soldered and subjected to waterproofing (hot melt) processing, and a part of the insert is exposed and positioned in the mold cavity. There is known a method in which a plastic resin is injected under pressure and the part is molded with the synthetic resin.

[0003] Conventionally, such a resin molded product is formed of a thermoplastic resin or a thermosetting resin alone, and appropriately contains a fibrous or powdery reinforcing material or filler. In addition, a synthetic resin is injected under pressure into a joint portion of two or more molded members in combination to fill and mold a gap.

In the case of molding with the above-mentioned conventional thermosetting resin, the flowability of the resin is generally too good, and the resin flows into the gap between the insert fitting and the mold during molding. As a result, the resin adheres to the surface of the insert fitting. Therefore, a so-called deburring operation for removing the resin adhering to the insert metal fitting is necessarily required, and this operation is very troublesome. For example, even if it is attempted to remove it using shot blasting, etc., it is not possible to completely remove the adhered resin, and if the adhered resin is removed manually, it may further damage the surface of the insert fitting. However, there is a problem that the insert fitting itself may be deformed, and the reliability of the component is reduced.

Further, when the thermosetting resin flowing into the gap between the insert fitting and the mold hardens, the gap is clogged, so that it is not possible to insert a new insert fitting, so that continuous molding cannot be performed. There was also.

[0007] Although efforts have been made to improve the accuracy of the gap between the insert fitting and the mold, there is a limit in the manufacturing accuracy of the insert fitting. Since the configuration is indispensable when the metal fitting is mounted on the mold, it is difficult to prevent the resin from flowing into this gap.

In this respect, molded articles formed of a thermoplastic resin have a drawback that the dimensional change under high temperature and pressure is large and the strength is inferior, but the thermoplastic resin is inferior in flowability unlike the thermosetting resin. For this reason, there is a fact that it is difficult for the resin to flow into the gap between the insert fitting and the mold. That is,
For example, if the gap is about 0.1 mm, the resin can be molded without adhering the resin to the surface of the insert and without closing the gap, so that there is no need to remove the resin adhering to the insert. Further, the resin does not clog the gap between the insert fitting and the mold.

In the present invention, first, the second molded article 2 provided with the insert fitting 3 is formed in advance with a synthetic resin having thermoplasticity. Examples of such thermoplastic resin include polyamide, polyacetal, and the like. Polycarbonate, polybutylene terephthalate, polyethylene terephthalate and the like are used. The reason why the second molded article 2 is formed of a thermoplastic resin in this manner is that the thermoplastic resin has poor fluidity, so that it is difficult for the resin to flow into the gap between the insert fitting 3 and the mold. This is because the second molded product 2 provided with the insert fitting 3 can be molded without adhering the resin to the resin and without closing the gap.
