Description
Technical field
The present invention relates to the plastic mould of common injection machine, mainly be meant the interior cold automatic water dividing gap mould that pulls of a kind of common injection machine mould.
Background technology
The injection machine of present most injection moulding company all is not possess the traditional common injection machine that matched moulds ejects function, and this common injection machine accounts for more than 99% share in the whole world.Simultaneously because the particularity of particular product structure, advancing glue can only advance in the fenestra of a very little spatial dimension or on the goods sidewall, product property often needs the big mouth of a river to advance glue could to guarantee, and big entry nozzle injection mold has only by the processing of artificial back and cuts the mouth of a river, the remaining big entry nozzle injection mold of only a few can be by complicated row position (being slide block again), high costs such as the high price cutter of rapid wear could be realized automation water dividing gap in the mould, in addition in the fenestra of little spatial dimension, advance glue, the artificial especially very difficulty of shearing.Other is as the thin mouth of a river of pin mark, the diving mouth, the banana mouth of a river (crying the ox horn mouth of a river again), the half banana mouth of a river (crying the half ox horn mouth of a river again, a kind of new mouth of a river between the diving mouth and the banana mouth of a river), the wire dot system hot water mouth, though the function that needle valve hot water mouth etc. can have automation in the mould to cut off the water supply mouthful, but price is high, or forming defect is arranged, and does not replace the big mouth of a river.Present mould more than 60% all is the common big mouth of a river, wipe out the mouth of a river by the processing of artificial back and could realize that the mouth of a river separates with goods: so human cost height, process that to wipe out mouth of a river otherness big after artificial, manually wipe out the mouth of a river and will use knife, the easy scratch of glue spare and bad, the also easy injured fatiguability of people.
Disclosed by retrieval document finds no the constructed of on plastic mould use and present technique and standardization cutter.
