Description

Mold with easily-detachable toothed loose core

Technical Field

The utility model relates to a mould, specific mould that can tear open fast when tooth core pulling structure causes the card to die because of the foreign matter and repair in order to improve mould availability factor, reduce cost of maintenance that says so.

Background

The core-pulling structure is very common in the mold, and the core-pulling mold structure limited by space is often encountered in the mold design process, and in this case, the core pulling is realized by changing the core-pulling direction. One of them is a tooth-shaped core-pulling structure.

The phenomenon of card dying appears easily in actual use in dentate structure of loosing core, and its leading cause is that dentate structure of loosing core is buried inside the mould, and the impurity that appears in the production process can not effectual discharge, thereby piles up at the dentate clearance and appear the phenomenon of card dying. After the jamming problem occurs, the existing transmission gear is of an integrated structure and is deeply buried in a die to be matched with a cavity, so that only a destructive disassembling mode can be adopted after the jamming occurs, the core rod or the transmission rod is damaged to carry out cleaning work, and the core rod or the transmission rod can be recovered to be used from the newly manufactured core rod or the transmission rod. Such cost is extremely high, and can waste a large amount of time cost, influences mould availability factor.

In conclusion, the tooth-shaped loose core which can be quickly disassembled and replaced after being clamped has important significance for maintaining and using the mold.
