Problems solved by technology

In the technology disclosed in Patent Document 2, although it is not as cumbersome to fasten the thread when installing the cooling pipe to the cooling hole, when the cooling pipe is inserted, the O-ring is easy to disengage or twist, and because the O-ring with a small wire diameter cannot Increased squeeze margin, so there is a problem that cooling fluid leaks easily from the gap between the O-ring and the cooling hole

Abstract

The invention provides a cooling pipe and a cooling structure of a mold. Operation for mounting into a cooling hole can be simplified, and meanwhile leakage of cooling fluid is not prone to happening.The cooling pipe inserted into the cooling hole formed in the mold comprises a pipe and a lip packing, wherein the pipe extends from the front end side to the rear end side along the axis, a groove recessed towards the inner side in the axis right-angle direction orthogonal to the axis is formed in the outer circumference, and the lip packing is arranged on the outer side in the axis right-angledirection of the bottom surface of the groove formed in the pipe; the groove has a first face facing the front end surface of the lip packing and a second face facing the rear end surface of the lip packing, the pipe is provided with a first portion and a second portion, a first face is formed at the rear end, a second face is formed at the front end, and the outer diameter of the outer peripheralsurface of the first portion is enlarged from the front end side to the rear end side.

Description

Technical field [0001] The present invention relates to a cooling structure of a cooling pipe and a mold, and in particular to a cooling structure of a cooling pipe and a mold that can simplify the work of mounting to a cooling hole. Background technique [0002] As a cooling structure of a mold for manufacturing a molded body by pressure casting, injection molding, etc., a structure is known that supplies a cooling fluid from a cooling pipe installed in a cooling hole formed in a mold to a cooling hole (Patent Documents 1 and 2). In order to prevent the cooling fluid from leaking from the cooling hole, in Patent Document 1, the cooling pipe is fastened to the cooling hole by screws, and in Patent Document 2, an O-ring mounted on the cooling pipe is interposed between the cooling pipe and the cooling hole.
