Abstract

PURPOSE:To prevent production of burrs at the front of a flange part and a fuel-air mixture passage due to welding, by a method wherein, on the back side of the flange part, the peripheral edge of the opening of the flange part is welded to the outer peripheral part of an intake manifold body. CONSTITUTION:An intake manifold body made of resin is a tubular branch pipe 1, and is divided in the direction of its length into two parts. The end part of the branch pipe 1 is engaged with the opening part of a flange member 10, and on the back 12 side of the flange member 10, the peripheral edge of the opening and the outer peripheral part of the branch pipe 1 are welded together for joining at 14. Flange parts 2c and 3c for positioning and welding are formed on the outer peripheral part of the branch pipe 1.

More specifically, the present invention relates to a method of separately molding the main body and flange member of the resin intake manifold and then welding and joining them.

Conventionally, it has been common to use die-cast aluminum because it has to be durable.

Especially when the flange member is used as a gasket, It is necessary to completely remove the pars on the front surface of the C21+, and furthermore, the pars formed on the wall of the mixture passageway (20a) cause intake resistance, so they also need to be completely removed.Therefore, complicated post-processing is required to remove the pars. required.

溶着工法を提供することを目的とする。In view of the above-mentioned points, the present invention provides that when the intake manifold body and the flange member are formed separately and then welded and joined together, the welding prevents the welding from occurring on the front surface of the flange member facing the cylinder head and inside the air-fuel mixture passage. The purpose is to provide a welding method that does not cause welding.

Then, the end of the main body is fitted into the opening of a flange member formed to have an opening large enough to fit the end of the main body, and then the end of the flange member is fitted on the back side of the flange member. The present invention relates to a method for manufacturing a resin intake manifold, characterized by welding the periphery of the opening and the outer periphery of the main body.
