Claims

[Scope of Claim for Utility Model Registration] A fixed side mold in which a plurality of sprues are formed, a movable side mold that can move toward and away from the fixed side mold, and a plunger fitted into the mold so as to be able to reciprocate and be parallel to each other. a plurality of injection cylinders arranged in a shape; a position adjustment means for moving each injection cylinder in a direction perpendicular to the injection direction and positioning the nozzle of the injection cylinder with respect to the sprue; and the plurality of injection cylinders. a movable table on which a movable table is mounted, which is movable toward and away from the stationary mold, and which brings the nozzle of the injection cylinder into contact with the opening of the sprue when approaching; and a connecting member to which the proximal end of each plunger is connected. , a drive source for reciprocating the plunger via the connecting member, and further comprising: a multi-cylinder type in which the nozzles of each of the injection cylinders are offset from the central axis of the injection cylinder in a direction in which they approach each other; Injection molding equipment.
