Description of the Related Art Generally, a radiator is mounted on a support bracket of a vehicle body via a mountaineing member after a shroud is mounted, or is integrated with a shroud via a mountaineer member on a support bracket provided on the vehicle body. It is attached together with the shroud.

[0003] As such a mounting structure of a radiator and a shroud, for example, one disclosed in Japanese Utility Model Laid-Open No. 58-193012 is known.

FIG. 6 illustrates an example similar to the mounting structure of the radiator and the shroud.

In the drawing, reference numeral 101 denotes a radiator, and mounting holes (not shown) are provided on the left and right sides of an upper tank 102 made of resin.
Are provided, and mounting pins 105 are integrally provided on the left and right sides of the lower surface of the resin lower tank 104.

Reference numeral 107 denotes a shroud made of resin,
An opening 109 is formed at the center of the reference numeral 08. A mounting hole 110 </ b> A is formed in a vertical flange 110 formed above the shielding plate 108. A mounting hole 111 is formed in a mounting flange 111 formed below the shielding plate 108.
A is drilled.

Next, the mounting structure of the radiator 101 having such a structure and the resin shroud 107 will be described.

First, the mounting pin 105 of the resin lower tank 104 of the radiator 101 is inserted into the mounting hole 111A of the mounting flange 111 of the resin shroud 107, the mounting hole 110A of the vertical flange 110, and the upper bracket of the upper tank 102. Bolt 1 in mounting hole 103
20 is inserted, the resin shroud 107 is formed.
Is attached to the radiator 101.

Next, the radiator 101 integrated with the resin shroud 107 inserts the mounting pin 105 of the resin lower tank 104 into the mounting hole 112A of the mountainous member 112, and further mounts the mountainous member. 1

In FIG. 1 and FIG. 4, reference numeral 15 denotes a rubber mountaining member having a mounting hole 16 into which a mounting pin 14A of a resin shroud 10 is inserted. A groove 15A is formed.

As shown in FIGS. 1 and 4, a support bracket 18 is provided on the vehicle body 17, and a support hole 18B into which the lower side of the mountain member 15 is inserted is provided on an upper surface 18A of the support bracket 18. Has been drilled.

In this embodiment, as shown in FIGS. 1 and 4, the lower side of the mountain member 15 is inserted into the support hole 18B of the support bracket 18 of the vehicle body 17 so that The mountaining member 15 is supported,
Further, with the mounting bracket 5 of the resin lower tank 4 of the radiator 1 placed on this mountaining member 15,
When the mounting pin 14A of the resin shroud 10 is inserted into the mounting hole 16 of the mountain member 15 via the mounting hole 6 of the mounting bracket 5, the resin shroud 10 is mounted on the support bracket 18 of the vehicle body 17 with the radiator 1. It is attached as one.

According to the above construction, the mounting pin 14A of the resin shroud 10 is inserted into the mounting hole 16 of the mounting member 15 through the mounting hole 6 of the mounting bracket 5 of the resin lower tank 4 of the radiator 1. Thus, the resin shroud 10 can be mounted on the support bracket 18 of the vehicle body 17 integrally with the radiator 1. That is, when the resin shroud 10 is mounted on the radiator 1 by using the mounting pins 14A of the resin shroud 10, the radiator is inserted into a hole of a support bracket of the vehicle body in order to mount the radiator on the vehicle body as in the conventional example. No mounting pin is required, and the structure can be simplified.

Next, a method of manufacturing the resin lower tank 4 having the mounting brackets 5, 5 according to the third and fourth embodiments of the present invention and a mold for manufacturing the same will be described with reference to FIG.

In the figure, a resin lower tank 4 is formed by pouring a resin material into a cavity formed by a pair of halves 8 and 9.

One of the molds 9 has a protrusion 9A reaching the flange 4B of the side surface 4A of the resin lower tank 4 and a boss 9 for forming a mounting hole located adjacent to the protrusion 9A.
B is provided.

The other mold 8 has a projecting portion 9A of the mold 9 reaching the flange 4B of the side surface 4A of the resin lower tank 4.
8A is provided.

Of course, the pair of halves 8 and 9
Concave portions are formed so as to form the contour of the resin lower tank 4, and these concave portions form a cavity. In addition, the mold 8 is provided with a concave portion forming a fan-shaped rising wall 5A of the mounting bracket 5, as shown by a dotted line in FIG. This rising wall 5A
It is connected to a plate-like portion 5B provided with a mounting hole 6.

When the lower tank 4 made of resin is formed by the pair of dies 8 and 9, the protrusion 9 A of one of the dies 9 is used simultaneously with the formation of the mounting hole 6 of the mounting bracket 5 by the boss 9 B. The flange portion 4B of the resin lower tank 4 is formed, and the protrusion 9A passes through the concave portion 8A of the slit forming die 8 adjacent to the mounting hole 6 of the mounting bracket 5 to form the slit hole 7. .

According to the above construction, when the resin lower tank 4 of the radiator 1 is formed, the mounting bracket 5
Although it is necessary to form the mounting hole 6 of the above, for this purpose, a pair of molds and a slide mold are generally required like the resin shroud 108 described in the conventional example.
Since the mounting bracket 5 has a slit hole 7 adjacent to the mounting hole 6, when the resin lower tank 4 is formed by the pair of dies 8, 9, the flange portion of the resin lower tank 4 is formed. The protrusion 9A of one mold 9 forming 4B is
A slit hole forming die 8 located between the mounting bracket 5 and a mounting hole forming boss 9B that forms the mounting hole 6 of the mounting bracket 5.
By passing through the concave portion 8A, the mounting hole 6 of the mounting bracket 5 can be formed without a slide die.

Accordingly, the recessed portion of the slit forming die 8 is located between the projecting portion 9A of the one die 9 and the mounting hole forming boss 9B forming the mounting hole 6 of the mounting bracket 5. 8A, the slit hole 7 is formed, so that the resin lower tank 4 is formed only by a pair of forming dies 8, 9, and a slide die for forming the mounting hole 6 is required. do not do.

As a result, the cost of manufacturing the mold for the lower resin tank 4 can be reduced, and the total cost of manufacturing the mold for the lower resin tank 4 and the mold for the resin shroud 10 can be reduced. The mold manufacturing cost can be made lower than before.

[0043]

As described above, according to the first and second aspects, the resin shroud can be mounted on the radiator using the mounting pins of the resin shroud. Therefore, unlike the conventional example, since the radiator is mounted on the vehicle body, the mounting pin of the radiator to be inserted into the hole of the support bracket of the vehicle body becomes unnecessary, and the structure can be simplified.

According to the third and fourth aspects, when the resin lower tank of the radiator is formed, it is necessary to form the mounting hole of the mounting bracket, and the mounting bracket is adjacent to the mounting hole. When the resin lower tank is formed by a pair of molds, the protrusion of one mold that forms the flange of the resin lower tank forms the mounting hole of the mounting bracket. The mounting hole of the mounting bracket can be formed without the slide die by passing through the concave portion for forming the slit hole of the other mold located between the boss portion for forming the mounting hole to be formed. Can be.

Therefore, the protrusion of one mold passes through the recess for forming the slit hole of the other mold located between the boss for forming the mounting hole forming the mounting hole of the mounting bracket. Since the slit hole is formed, the molding of the resin lower tank requires only a pair of molding dies, and does not require a slide mold for forming the mounting hole. As a result, the cost of manufacturing the mold for the resin lower tank can be reduced, and the total cost of manufacturing the mold for the resin lower tank and the mold for the resin shroud can be reduced. Can also be cheaper.
