Abstract

A joining member configured to join a temperature-controlled member and a temperature control jacket includes a temperature control jacket attachment part attached to the temperature control jacket, and a temperature-controlled member attachment part attached to the temperature-controlled member. The temperature control jacket attachment part includes a temperature control jacket-side opening into which a first bolt is insertable, and the temperature-controlled member attachment part includes a temperature-controlled member-side opening into which a second bolt is insertable. The temperature control jacket-side opening and/or the temperature-controlled member-side opening are configured to allow change in positions where the first and second bolts are inserted.

Claims

1. An injection molding machine comprising:

a temperature-controlled member;

a temperature control jacket that includes a flow channel or a cooling element and is removably placed on a peripheral surface of the temperature-controlled member; and

a joining member configured to join the temperature-controlled member and the temperature control jacket, wherein

the joining member includes;

a temperature control jacket attachment part attached to the temperature control jacket; and

a temperature-controlled member attachment part attached to the temperature-controlled member,

the temperature control jacket attachment part includes a plurality of first openings into which a plurality of first fixing members is insertable in order to join the joining member and the temperature control jacket,

the temperature-controlled member attachment part includes a plurality of second openings into which a plurality of second fixing members is insertable in order to join the joining member and the temperature-controlled member,

at least one of the plurality of first and second openings is configured to allow change in a position where the corresponding first or second fixing member is inserted in the opening,

the joining member comprises a block body having a first face and a second face, perpendicular to the first face, wherein the temperature control jacket attachment part is on the first face, and the temperature-controlled member attachment part is on the second face,

the plurality of first openings is in the first face of the block body, wherein the plurality of first openings extends parallel with each other,

the plurality of second openings is in the second face of the block body, wherein the plurality of second openings extends parallel with each other,

the temperature-controlled member attachment part has a curved surface that is curved along the peripheral surface of the temperature-controlled member,

the plurality of first openings is arranged along a curvature corresponding to the curved surface of the temperature-controlled member attachment part,

the plurality of second openings is aligned along an axis of the temperature-controlled member,

the plurality of first openings includes a first group of first openings and a second group of first openings, and

the plurality of the second openings is positioned between the first group of first openings and the second group of first openings, and at a top of the curvature along which the plurality of first openings is arranged.

2. The injection molding machine according to claim 1, further comprising

a temperature sensor in the temperature-controlled member, wherein

positions of the temperature control jacket and the temperature sensor are changeable by change in a position where the corresponding first or second fixing member is inserted in said at least one of the plurality of first and second openings.

3. The injection molding machine according to claim 1, wherein

said at least one of the plurality of first and second openings is formed of at least one of a slot, a notch, and a round hole.

4. The injection molding machine according to claim 1, wherein said at least one of the plurality of first and second openings is configured to allow change in a position of the temperature control jacket relative to the temperature-controlled member by changing the position where the corresponding first or second fixing member is inserted and fixed in the opening.

5. The injection molding machine according to claim 1, wherein the molding machine comprises a plurality of the joining members.
