Abstract
A flange is formed on a heating cylinder in a vicinity of a center in a longitudinal direction and a predetermined joining plate adheres to the flange. A flange plate is provided on a support frame. The joining plate is fixed to the flange plate to attach and detach freely, and the heating cylinder is caused to be supported by the support frame. Accordingly, movement in an axial direction and rotation of the heating cylinder are restricted. A guide portion for positioning during attachment and detachment is provided on one or both of the joining plate and the flange plate.
Claims7
An injection device comprising:
- a heating cylinder;
- a screw provided to be drivable in an axial direction and a rotation direction inside the heating cylinder;
- and
- a support frame supporting the heating cylinder,
- wherein the heating cylinder is supported by the support frame in a state in which movement in the axial direction and rotation are restricted at a support position, the support position being a position close to a distal end portion by ⅓ to ⅔ of a length of the heating cylinder from a rear end portion of the heating cylinder,
- wherein a flange is formed on the heating cylinder at the support position,
- wherein the support frame includes a flange plate,
- wherein the heating cylinder is supported by the support frame due to the flange being fixed to the flange plate,
- wherein a joining plate is fixed to the flange and sandwiched between the flange and the flange plate,
- wherein the flange is detachably fixed to the flange plate via the joining plate, and
- wherein a guide portion is formed on one or both of the joining plate and the flange plate, and the joining plate is positioned by the guide portion to be fixed to the flange plate.
An injection device comprising:
- a heating cylinder comprising a front cylinder having a first flange and a rear cylinder having a second flange;
- a screw provided to be drivable in an axial direction and a rotation direction inside the heating cylinder;
- and
- a support frame supporting the heating cylinder, the support frame comprising a flange plate that is located behind the second flange in the axial direction,
- wherein the front cylinder and the rear cylinder are integrally fixed to each other by the first flange and the second flange being fixed to a joining plate, and
- wherein the heating cylinder is supported by the support frame in a state in which movement in the axial direction and rotation are restricted at a support position, the heating cylinder being supported by the support frame due to the joining plate being fixed to the flange plate.
