<p>A resin molding method comprising a cleaning step comprising injecting a molten resin from a resin injection unit under such a condition that the matching portions of dies can be somewhat spaced from each other by loosening clamping of the dies to thereby permit the molten resin to flow into a cavity and a gap between the matching portions of the dies, and discharging a molding integrally formed by the cavity and the gap between the matching portions of the dies after the molten resin has solidified. Thus an attachment attached to the gap between the matching portions of the dies is mixed into moldings formed in the cleaning process, so that the attachment is discharged together with the moldings upon ejection of the moldings. Accordingly, cleaning can be positively and efficiently effected without expenses and without lowering an efficiency of the molding operation.</p> |
