摘要:
First and second constituting components (21, 22) are injection-molded and joined within one pair of molds (61, 62). In order to join the first and second constituting components (21, 22), one of the respective regions (A1, A2) of the first and second constituting components (21, 22) abutted to each other is pushed into the other.

A liquid discharge head unit is positioned in high precision when mounted on the carriage of a liquid discharge recording apparatus. For the liquid discharge head unit, a side extrusion formed in column, which is rotatively supported in carriage, presses the upper surface of guide ribs formed on both side ends on the upper rear portion. This upper surface is made higher toward the rear side in order to effectuate the substantially horizontal movement of the pressurized position from the front side to the rear side. Then, the liquid discharge head unit is rotated around the side extrusion formed in column so as to be mounted on the carriage smoothly. Lastly, a guide pin, a rear extrusion, and a lower extrusion are allowed to abut against the corresponding portions of the carriage by means of pressure exerted on a receiving rib in order to perform positioning in the front, rear, left, right, up and down directions exactly. Also, by means of pressure exerted on the side face, the side extrusion is allowed to abut against the corresponding portion of the carriage to position the circumference of the guide pin in the rotational direction.

Provided is a method for manufacturing a liquid-ejecting head whereby in die slide injection molding it is possible to stably inject resin in secondary molding without damaging the shapes of parts that were formed in primary molding. In order for that, in the connecting section in which a convex section (H521) of a cover member (H121) is inserted into an opening (H500) of a liquid-supply member (H100), the closest distance (t2) to the opening in the area where secondary resin is injected is made larger than the gap (t1) between the opening (H500) and the convex section (H521). As a result, the resin is prevented from flowing into a liquid path (H501) during the secondary molding.

A head chip and a recording liquid storing unit are bonded through a sealing member. The head chip comprises a recording element base plate, and a flow path formation member provided with a bonding face and a supply hole. The frame member of the recording liquid storing unit is formed by a single member, which is provided with a recording liquid storing chamber, one side face of which forms a totally open portion. The shape of the opening portion is equal to the sectional shape of the recording liquid storing chamber. For the flat portion of the sealing member, there are formed a hole portion, the circumferential first face-side ribs that surround it, and the second face-side ribs, which are exactly symmetrical to the first face-side ribs, with the flat portion between them. These ribs are compressed and held by both bonding faces. An inner extrusion of the rib on the flat portion is fitted into the position hole of the bonding face. Through the sealing member thus arranged, the recording liquid storing unit and the head chip are connected to simplify the connecting structure.

A liquid discharge recording head (15) comprises an orifice plate (6) having a discharge port (6a) formed therefor to discharge liquid, and the main body portion (20) having liquid flow paths formed therein to be communicated with the opening arranged at the edge portion thereof, the discharge port and the opening being bonded to communicate with each other. For this liquid discharge recording head, a sealing groove (11b) is arranged on the circumference of the opening (11g) along the bonded face (11h), and filler is filled in the sealing groove, hence making it possible to pour filler into the sealing groove from the injecting groove (21) after the orifice plate is bonded to the face having the opening formed therefor to communicate the opening (2) with the discharge port of orifice plate so as to eliminate any gaps from which filler leaks between the orifice plate and the face having opening formed therefor, and carry out sealing by distributing filler over the entire area of sealing groove in an amount required for sealing appropriately without clogging the circumference of opening or discharge port.
