特公平２−３８３７７号公報 In general, in this kind of housing, a housing body in which a light source (bulb, bulb, light emitting diode, etc.) is assembled and a lens portion formed of a translucent resin material are abutted and the abutting surface is adhered. A die slide injection method is known as a manufacturing method of such a device (see, for example, Patent Document 1). In this product, the primary product 燈 body and lens part are injection molded with the movable mold and fixed mold facing each other, and then the movable mold is slid to match each primary product. Mold matching is performed, and a resin material is secondarily injected into a butt portion between primary products to integrally mold the casing.

。 By the way, in some cases, the die slide injection method is used in order to increase the amount of light and to secure a wide irradiation range, by making the inner surface of the main body into a mirror state as a reflecting surface (reflector). However, it has not been proposed to make the inner surface of the cocoon body a reflective surface, so the primary injected cocoon body is once taken out of the mold and the inner surface of the cocoon body is formed as a reflective surface such as vacuum deposition or sputtering. After forming the reflecting surface by using the technique, it is set again on the mold and the butt portion of the primary product is secondarily injected to unify the eyelid body and the lens portion.
Today, however, the lens cut surface has been reduced in the lens part, and the inner surface (reflective surface) of the heel body has been well-understood. In particular, the reflective surface has fingerprints and scratches. In this case, since these can be seen from the outside through the lens part, it becomes a defective product, and therefore it is necessary to be careful in handling the body body after forming the reflecting surface, so that the workability is poor and the yield is low. There is a problem to be solved by the present invention.

2, mold surfaces 1 a and 2 a forming the heel body 3, mold surface 1 b forming the lens part 4,
The two molds face each other in a state of being separated from each other, and the movable mold 1 is moved to the fixed mold 2 side from the separated state, and the opposed mold surfaces are matched (primary matching process: FIG. 2 (B)). In this mold-matching state, primary injection is performed, and the main body 3 and the lens unit 4
Are injection-molded (primary injection step: see FIG. 2C).

At this time, the main body 3 is supported on the movable mold 1 side (remaining), The mold is designed so that the lens unit 4 is supported (remains) on the fixed mold 2 side. Next, the movable mold 1 is moved in parallel so that the bag main body 3 faces the vacuum deposition apparatus 5 (see FIG. 3B), and then moves to the fixed mold 2 side to be in a mold matching state (secondary matching). Step: see FIG. 3C). In a state where the molds 1 and 2 are separated from each other before or after the parallel movement, a portion where vacuum deposition is not desired,
Here, the cover member 13 for covering the terminal 10 of the bag main body 3 and the insertion portion 3a of the valve 11 is incorporated (inserted) into the bag main body 3 (cover member assembling step). The cover member 13 is incorporated in the previous stage. In addition, the concave mold surface 2c that houses the vacuum deposition apparatus 5 is designed so as to cover the butting surface 3b with the lens portion 4 of the bag main body 3 so as not to be vacuum deposited.

The molten metal is vaporized, and the exposed inner surface of the bag body 3 is vacuum-deposited to form the reflecting surface 14 (reflecting surface forming step: see FIG. 4A). Next, after moving the movable mold 1 away from the fixed mold 2 (see FIG. 4B), the movable mold 1 is moved in parallel with respect to the fixed mold 2 so that the rod body 3 and the lens unit 4 face each other. (See FIG. 4C). Incidentally, before and after moving the movable mold 1 in parallel, a step of removing the covering member 13 and a step of incorporating the necessary terminals 10 and valves 11 can be performed. In this embodiment, the separation before the parallel movement is performed. The removal step and the incorporation step are executed at the step where the movement is completed.

繰り返されるようになっている。 After that, the movable mold 1 is moved to the fixed mold 2 side so that the main body 3 and the lens unit 4 are brought into contact with each other (
Tertiary butting process: see FIG. 5 (A)), the resin material 12 is secondarily injected to the butting surface of the collar body 3 and the lens part 4 (secondary injecting process: see FIG. 5 (B)), thereby The main body 3 and the lens unit 4 are integrated to form a main body 9 in which a reflecting surface 14 is formed. Then, the movable mold 1 is separated from the fixed mold 2 and the molded housing 9 is taken out (see FIG. 5C). After that, the movable mold 1 is moved as shown in FIG. The translation is made to the initial position, and this process is repeated thereafter.

生を大幅に低減できることになる。 In the embodiment of the present invention configured as described above, when manufacturing the casing 9, the primary injection molding process for forming the casing body 3 and the lens section 4, and the casing body 3 and the lens section 4 are combined. As a result of providing a reflection surface forming step for forming the reflection surface 14 on the inner surface of the bag main body 3 during the secondary injection step for integration, the bag main body once taken out of the mold as in the past As in the conventional case where the reflecting surface is formed on the plate 3 and then set on the mold again, it is not necessary to take out and re-set the bag body 3 in a series of injection molding processes. A reflective surface can be formed on the main body 3 and work efficiency is improved. Moreover, since the bag body 3 is not taken out and re-set, the reflective surface 14 is not touched with a finger to get a fingerprint or hit with an object, and the generation of defective products can be greatly reduced.

の過程で全ての製造作業が円滑に実行され、効率の良い燈体９の製造ができる。 In addition, since the concave mold surface 2c in which the vacuum vapor deposition apparatus 5 is accommodated is formed in the second mold 2 that is a fixed mold, the vacuum vapor deposition apparatus 5 is provided on the movable mold 1 side. As a result, there is no problem that the molten metal in the boat 7 spills out.
Furthermore, in this case, a portion where the reflecting surface is not desired to be formed, that is, the terminal 10 and the bulb 11 is used.
If the reflective surface is formed with a metal film on the mounting portion 3a, the insulation is impaired and the circuit is short-circuited. Therefore, the reflective surface 14 is formed after the portion is closed by the plugging member 13. The housing 9 has no problem. Moreover, since the terminal 10 and the valve 11 are assembled after removing the blocking member 13 after forming the reflecting surface 14, all manufacturing operations are smoothly executed in a series of injection molding processes, and the efficiency is improved. A good housing 9 can be manufactured.

移動方向とが同じ方向となる結果、型移動機構の構成を簡略化できるという利点がある。 Moreover, the concave surface 2c for accommodation of the vapor deposition apparatus 5 formed in the fixed mold 2 is composed of the bowl body 3 and the lens portion 4.
Between the mold surfaces 2a and 2b for forming the movable mold 1 so that the movable mold 1 is moved from the primary injection process to the reflective surface forming process and movable from the reflective surface forming process to the secondary injection process. As a result of the movement direction of the mold 1 being the same direction, there is an advantage that the configuration of the mold movement mechanism can be simplified.
