Abstract

There is provided a manufacturing method for molding a liquid supply member by using a first mold and a second mold in which the first mold is capable of being slid relatively to the second mold, the method including a first molding step of performing injection molding to form a first and second component parts of the liquid supply member at different positions from each other, an evacuating step of sliding the formed second component part in a direction intersecting with a direction of sliding of the first mold relative to the second mold and with a direction of the opening and the closing the first and the second mold, a contacting step of bringing the formed second component part into contact with the molded first component part, and a second molding step of performing injection molding to join the first component part and the second component part.

First claim

What is claimed is:

1 . A manufacturing method for molding a liquid supply member by using a first mold and a second mold which are capable of opened and closed relative to each other and in which the first mold is capable of being slid relatively to the second mold, the method comprising:
a first molding step of performing injection molding to form a first component part of the liquid supply member and a second component part of the liquid supply member other than the first component part at different positions from each other, with the first and the second mold closed relative to each other; an evacuating step of sliding the formed second component part in a direction intersecting with a direction of sliding of the first mold relative to the second mold and with a direction of the opening and the closing the first and the second mold; a contacting step of sliding the first mold relative to the second mold and bringing the formed second component part into contact with the molded first component part; and a second molding step of performing injection molding to join the first component part and the second component part with the first and the second mold closed relative to each other.

2 . The manufacturing method according to claim 1 , wherein the second component part is joined to the first component part at a position inside the first component part in the direction of the opening and the closing the first and the second mold.

3 . The manufacturing method according to claim 1 , wherein the second component part is joined to the first component part to form a hollow portion in the liquid supply member.

4 . The manufacturing method according to claim 1 , wherein an injection molding material in the second molding step is a same material as a material of the first and second component parts.

5 . The manufacturing method according to claim 1 , wherein an injection molding material in the second molding step includes filler.

6 . The manufacturing method according to claim 1 , wherein the second component part includes a plurality of convex portions inside of which has a concave shape, on an opposite surface to a surface of the second component part that is brought into contact with first component part.

7 . The manufacturing method according to claim 6 , wherein the concave shape in the inside of the plurality of convex portions forms a conic shape in which a peripheral surface forms a taper, with respect to the surface of the second component part on which the plurality of convex portions are provided.

8 . The manufacturing method according to claim 1 , wherein a position at which the second component part is formed in the first molding step, a position into which the second component part is slid in the evacuating step, and a position at which the second component part is joined to the first component part in the second molding step are different from each other.

9 . The manufacturing method according to claim 1 , wherein the second molding step performing filling of an injection molding material trough a cylindrical portion made with the first component part and the second mold.

10 . The manufacturing method according to claim 1 , wherein the first component part and the second component part are joined to form a flow path for supplying ink to a printing element part for ejecting ink.
