Then, the pressing direction is the depth h, and the vertical direction of the inclination direction is the depth h.
-It becomes cosθ. Here, by adjusting the pressing forces F and F ₀ , the depth h of the welding margin 90 at the first and second flat joints 81 and 83 is set to 1.5 mm, and the inclination angle θ
Is in the range of 0 to 90 °, the first and second inclined joints 8
Table 1 is obtained by comparing the depth h · cos θ of the welding margin 90 at 2, 84.

代９０が低下することがわかる。[Table 1] From Table 1, the resin-made intake manifold has the first and second flat joints 8.
Even if the welding margin 90 at 1, 83 is sufficiently secured, the inclination angle θ
It can be seen that the welding margin 90 at the first and second inclined joints 82 and 84 decreases as the number increases.

FIG. 22 shows that the smaller the welding margin 90, the lower the tensile strength. For this reason, when the joining strength of the first and second inclined joining portions is not sufficient,
It can be seen that the first and second inclined joints are easily broken. For example, if the resin product is a hollow product such as a resin intake manifold, the resin product may be broken when the internal pressure is large.

As shown in FIG. 24, the burrs 6 generated at the first and second flat joints 81 and 83 become the first and second inclined joints 8.
Since the number of burrs is increased as compared with the burrs 6 generated at 2 and 84, it is necessary to increase the burr storage space C secured by the concave portions 91e and the like.

For example, if the resin product is such a resin intake manifold, the degree of freedom in the engine room is limited. SUMMARY OF THE INVENTION The present invention has been made in view of the above-described conventional circumstances, and is a resin product by joining first and second joining resin members having first and second planar joining portions and first and second inclined joining portions. It is an object of the present invention to make the joint strength of the resin product sufficient and not to increase the burrs generated at the first and second flat joints more than necessary.

がわかる。FIG. 8 shows that in the conventional manufacturing methods of Comparative Examples 1 and 2, although the bonding strength at the first and second planar bonding portions 81 and 83 is strong, the bonding strength at the first and second inclined bonding portions 82 and 84 is high. It can be seen that when the depth h of the welding margin 90 is small, the pressure resistance is small. Therefore, it is understood that the set welding margin 90 must be increased in the conventional manufacturing method. On the other hand, in the manufacturing method according to the first embodiment, the joining strength at the first and second planar joining portions 81 and 83 and the joining strength at the first and second inclined joining portions 82 and 84 are substantially equal.
It can be understood that a large withstand pressure can be obtained even when the depth h of the metal is small.

For this reason, this resin-made manifold is provided with the first and second inclined joints 82,
84 withstands large internal pressure and is hard to break. In addition, since the welding margin 80 of the first and second inclined joints 82 and 84 can be sufficiently secured together with the first and second planar joints 81 and 83, the welding margin 80 of the first and second planar joints 81 and 83 can be secured. Never be too large. For this reason, the burr 6 generated at the first and second planar joints 81 and 83 is almost the same as the burr 6 generated at the first and second inclined joints 82 and 84.

The left half of the first and second joints 91b and 92b is pressed at a substantially right angle. At this time, for example, the inclined surface 21b and the left movable mold 2
FIG. 11 is a vector diagram showing the relationship between the force and the force 3. As shown in FIG. 11, assuming that the inclination angle of the inclined surface 21b is φ and the reaction force generated on the left movable die 23 is F ₀ ′, the left movable die 23 has T = F _{0 in} the vertical direction of the inclined surface 21b. '· Cosφ acts.
