DEVICE FOR CALIBRATION OF THE EXTRUDED PLASTIC STRUCTURAL SHAPE FORMING AT LEAST ONE LENGTHWISE GROOVE Russian patent published in 2008 - IPC B29C47/90 

FIELD: chemical industry; other industries; devices for calibration of the extruded plastic shapes.

SUBSTANCE: the invention is pertaining to the device for calibration of the extruded plastic shape forming at least one lengthwise groove. The device contains the calibrating body receiving the structural shape exiting from the form-shaping die. The calibrating body includes the molding extension piece passing in the direction of the movement of the structural shape and inserted in the lengthwise groove. The molding extension piece has the cooling channel and the cooling holes. The cooling holes are passing across the molding extension piece and intersect its cooling channel. The cooling channel open on the both butt sides through the through groove is connected with the receiving pit used for the terminal clamps. The receiving pit intersects the calibrating body in the direction of passing and is disposed in the field of the cooling holes. The terminal clasps form the coupling holes used for the streamwise joining between the cooling channel and the appropriate cooling holes. The invention allows to simplify cooling of the structural shape in the field of the molding extension piece.

EFFECT: the invention ensures the possibility to simplify cooling of the structural shape in the field of the molding extension piece.
