Description
Technical field
The present invention relates to die casting machine feeder equipment technical field, more particularly to reducing high sealing injection device.
Background technology
Conventional injection rod and connector, drift does not have any lubricant passage way, and extra increase oil spout by die casting machine is leaned against entirely
Device fueling injection equipment is not that what is carried dispatched from the factory in die casting machine producer, and these expenses are all settled a dispute by the parties concerned themselves by die casting machine user and (entrusted
Outer processing, or commission offer feed device side is ask to process this processing time consuming with high costs and arduously bring no small fiber crops to supply both sides
It is tired.) drift high temperature after a secondary aluminium water is impacted burns lubricating oil, needs oil jet lubrication again, impact is once stopped spray one
Secondary is that efficiency is had a greatly reduced quality, and lubricating oil cost is also very important, and the lubricating oil sprayed on the contrary not enough uniformly causes friction resistance force
Lifting reduces the life-span of molten cup drift.Lubricating arrangement is installed and make it that live in disorder pipeline is various.
It with the diameter that gives up from tens millimeters to hundreds of mm lengths is also so to melt that conventional drift and molten cup, which is,
Cup key even more so is that material is not also that common iron is mould steel H13, and cost is very high, and luminescent material expense just allows very
Many industry headaches, when can not settle accounts in time to supplier especially with side, what material supplier was strong in addition urges money attitude, with regard to shape
Into common business chain debts relation, its consequence is self-evident, why can show this farce much relations and be to rush
This service life of head is too low, because drift and molten cup are wanted aluminium water propulsion mould, the gap of drift and molten cup be several silks with
Interior, the too big aluminium water in gap, which runs out of molten cup, makes the formed product inside mould have critical defect, and gap too less friction resistance increases
Die casting machine service life can be reduced, the big molten cup of the post gap of multiple repeated stock and drift, which are just scrapped, must just remake.
The installation of current feed device is very high to the concentricity requirement for melting cup and injection bar assembly, and slightly deviation can go out
Existing card drift, on-site noise increase, a series of problems, such as frictional resistance improves reduction service life etc., the requirement to operating personnel
It is very harsh so that set-up time extension reduction production efficiency, run counter to the theory efficiently quickly produced instantly.Installation requirement
Height, and high is required to operating personnel's specialized capability.
