Centrifugal casting mold and centrifugal casting mold assembly device

Abstract

A mold used for centrifugal casting includes a mold body formed in a cylindrical shape and a lid member ( 40 ) that is detachably assembled to an end part of the mold body in an axial direction. The lid member includes a lid body ( 41 ) that is attached to an opening part formed at the end part of the mold body, a protrusion part ( 450 ) that is fitted to the mold body, and a spring that applies elastic force to the lid body in a direction in which the lid body closely contacts the mold body.

What is claimed is: 
     
         1 . A centrifugal casting mold assembly for a centrifugal casting mold used for centrifugal casting and including a mold body and a lid member, the mold body being formed in a cylindrical shape, the lid member being detachably assembled to an end part of the mold body in an axial direction, wherein the lid member includes
 a lid body that is attached to an opening part formed at an end part of the mold body,   a fitting part that is fitted to the mold body, and   an elastic force application part that applies elastic force to the lid body in a direction in which the lid body closely contacts the mold body, and,   
       the assembly device includes:
 an attachment-detachment device configured to attach and detach the lid member to and from the end part of the mold body; and 
 a control device configured to control the attachment-detachment device, wherein 
 the attachment-detachment device includes
 a grasping unit configured to grasp the lid member, and 
 an image capturing unit provided at the grasping unit, and 
 
 when attaching the lid member to the mold body, the control device grasps the lid member with the grasping unit, and then captures an image of the end face of the mold body with the image capturing unit, detects the position of the mold body relative to the grasping unit based on image data obtained by the image capturing, and fits the fitting part of the lid member to the mold body by displacing the grasping unit based on the position of the mold body. 
 
     
     
         2 . The centrifugal casting mold assembly device according to  claim 1 , wherein
 the attachment-detachment device further includes a position detection unit configured to detect the position of the grasping unit relative to the mold body in an axial direction of the mold body, and   the control device fits the fitting part of the lid member to the mold body by further displacing the grasping unit based on the position of the grasping unit detected by the position detection unit.   
     
     
         3 . The centrifugal casting mold assembly device according to  claim 1 , wherein the control device displaces the grasping unit in a direction in which the fitting part of the lid member is fitted to the mold body, and then captures an image of the end face of the mold body with the image capturing unit, determines whether the fitting part of the lid member is fitted to the mold body based on image data obtained by the image capturing, and determines that the attachment of the lid member to the mold body is normally performed when having determined that the fitting part of the lid member is fitted to the mold body. 
     
     
         4 . The centrifugal casting mold assembly device according to any one of  claim 1 , wherein when detaching the lid member from the mold body, the control device captures an image of the end face of the mold body with the image capturing unit, detects the position of the mold body relative to the grasping unit based on image data obtained by the image capturing, grasps the lid member with the grasping unit by displacing the grasping unit based on the position of the mold body, and then cancels a state in which the fitting part of the lid member is fitted to the mold body by further displacing the grasping unit.
