초록 ▼

A fuel tank of synthetic resin is provided with a holding plate of synthetic resin arranged within the tank, and an outside wall covering the holding plate and formed by blow molding. Parts such as a level gauge projecting from the outside wall and having a nipple portion are held to the holding plate. At the manufacturing state of the tank, parts are fixed to the holding plate, and in this state, a blow molding mold is set and the outside wall of the tank is formed by the blow molding. In this case, the outer periphery of the holding plate is fixed to the inner circumferential surface of the outside wall, and the inner circumferential surface of the outside wall is pressed to the outer circumferential surface of the nipple portion of the component part and the circumference of the nipple portion is sealed. And then the outside wall covering the top end surface of the nipple portion is cut thereby the tank is manufactured.

Method of manufacturing a fuel tank of synthetic resin which is provided with an upper chamber filled with activated carbon to adsorb fuel evaporation gas, a lower chamber for storing fuel, an insert member arranged within the tank, and a tank outside wall constructed of a circumferential wall of the upper chamber and the lower chamber said outside wall covering said insert member and formed by blow molding using a parison of thermoplastic resin and a mold for blow molding to form a cavity of prescribed shape at a mold tightening state, said outside wall having an upper wall with a nipple portion for fuel evaporation gas which projects upward, a bottom wall and a side wall, said insert member being composed of a component part with a nipple portion projecting from the lower chamber to upper side of the upper wall and a holding plate of synthetic resin holding said component part and acting as a partition wall between the upper chamber and the lower chamber, said holding plate having a base portion of a flat plate shape arranged in the horizontal direction and an upper pipe portion for fuel flow projecting to an upper side of the upper wall and penetrating it, and a lower pipe portion for fuel evaporation gas projecting from the base portion to a lower side of the bottom wall and penetrating it, said method comprising the steps of: (a) arranging the axial direction of the nipple portion of the component part in a perpendicular direction to the base portion of the holding plate and fixing the component part to the holding plate and assembling said insert member; (b) setting said insert member into the mold, which is in an open state, so that the base portion of the holding plate is arranged in a perpendicular direction to the mold tightening direction of the mold; (c) arranging the parison around said insert member and the base portion of the holding plate; (d) tightening the mold and thereby pressing the parison against the outer periphery of the holding plate and also thereby pressing an outer circumferential surface of the nipple portion of the component part and the outer circumferential surface of the upper and lower pipe portions of the holding plate, the parison surrounding said nipple portion to form a covering portion, said nipple portion being pressed into a protruded section of the mold cavity, and injecting air into the parison to thereby press the parison against an inner circumferential surface of the mold, thus forming said outside tank wall by blow molding; (e) removing a molded article from the mold, said molded article being molded by the mold; (f) cutting and removing the parison covering respective top end surfaces of the nipple portion of the outside tank wall and the nipple portion of the component part and the upper and lower pipe portions of the holding plate in the molded article removed from the mold; and (g) filling the upper chamber with the activated carbon.
