Abstract

[Problem] To provide an in-mold detachable stamping device, in which rotation of the indicator does not lock even after repeated rotation to change the stamp mark. [Solution] A stamping device: which is provided with a roughly cylindrical outer marking shell that is fitted into a shaping mold, an indicator that is fitted inside said outer marking shell and is capable of angular displacement around the axial line, a cover that screws onto the lowermost section of the outer marking shell, and a spring for biasing the indicator with a downward force; and in which the stamp marking section is formed on surfaces of the outer marking shell and the indicator. The in-mold detachable stamping device is characterized in that: the indicator is provided with an indicator section that faces onto the inner surface of the mold, a positioning section extending downward from the indicator section, and a shaft section extending downward from the positioning section; the shaft section has a threaded part at the lower end; the spring has an engaging section that engages with the indicator and a fixing section that is fixed to the cover; the pitch of the spring in the engaging section and the pitch of the threaded section are equal; and the engaging section is engaged with the threaded section.

Description

technical field [0001] The present invention relates to a marking device for marking on a molded surface as the mold is being formed, and in particular to an in-mold removable marking device which does not lock the rotation of the marking body even if the marking body is repeatedly Turn to switch the marker indication. Background technique [0002] The date of manufacture, lot number, product number, etc. are usually provided on the molding surface, and these indications are used for researching causes of defects in molding and for inventory control. The indicating body includes a marker indicating portion, which is attachably and detachably inserted into an inner surface of a molding die, and then molded as the indicating body is inserted thereinto. As a result, these instructions (completely including the marking content of the instruction body) are marked and shaped on the molding surface. [0003] Patent Document 1 discloses a marking device including such an indicatin...
