In the core forming the inner surface of 24, a draft angle of one side θ can be ensured. Therefore, the side wall portion on which the guide rib 28 is formed
The inner surface of 24, 24 does not become undercut or release resistance, and the housing 11 can be easily formed by injection molding using a mold with a simple configuration that does not use a movable piece (slide piece) or reduces it. They can be formed integrally. Therefore, the space for accommodating the movable parts can be reduced, and the mold and the injection molding machine can be miniaturized to an optimum size for the product size, and a multi-cavity mold excellent in mass productivity can be obtained. At the same time, the mold structure can be simplified by reducing the number of movable parts, so that the cost of mold production is reduced, maintenance is facilitated, and furthermore, the breakage and failure of the mold are suppressed, and the durability is improved. Cost can be reduced. That is, usually, the size of the mold mounting die is set to match the injection capacity, so when the size of the mold is increased to incorporate a movable mechanism or the like, an injection molding machine having an excessive injection capacity is required. In this embodiment, molding is performed using only a part of the capacity of the injection molding machine. This makes it possible to attach to a molding machine, thereby reducing molding costs.

If the draft angle required in normal injection molding, for example, θ is 1.5 degrees, the housing
11 can be released smoothly, and for example, if the drawing stroke is 100 mm in the present embodiment, the opening amount between the upper holders 13, 13 (see FIG. d) increases only by about 5 mm and does not cause any problem in appearance.

As described above, the upper holders 13, 13
