Abstract
Hot flow path heat-insulating type flange arrangement, the present invention relates to thermoplastic processing technical field, refers in particular to one kind during thermoplastic processing, fixes the main heat-insulating type flange arrangement for filling nozzle of TOP-TIP.It is achieved by the following technical solution：Hot flow path heat-insulating type flange arrangement, including main filling nozzle and flange, also including heat insulation cap mold insert, heat insulation cap lining is padded in the annular groove in flange, and it is one overall that be connected for heat insulation cap mold insert, main filling nozzle and flange by jump ring.Described heat insulation cap mold insert is plastic material.The present invention is plastic material due to heat insulation cap mold insert; when installation mold is collided; the power that flange is directly acted on main filling nozzle can be alleviated; play a part of the main filling nozzle of protection; heat insulation cap mold insert avoids main filling nozzle and flange directly contact; the loss of heat transfer is effectively reduced, the shear heat of the plastic cement inside main filling nozzle is reduced, makes needle temperature control more accurate.
Description
Technical field
The present invention relates to thermoplastic processing technical field, one kind is referred in particular to during thermoplastic processing, fix hot flow path system
The main heat-insulating type flange arrangement for filling nozzle of system.
Background technology
With the great Hang Qi cities of oil product（Such as plastics, synthetic rubber）So that hot flow path processes rapid rising, more next
More traditional moulds start to be transformed into New type hot runner system mould, and the wherein appearance of hot flow path substantially increases many factories
Production efficiency.It is known that hot flow path is to the plastic cement that molten condition is injected in client's mould 3, such as accompanying drawing by main filling nozzle 1
Shown in 1.All it is generally the main filling nozzle 1 that TOP-TIP is directly fixed with flange 2 in existing hot flow path industry, it is to heat
Flow passage system plays positioning action, while being also the location structure of the relative injection machine of whole set of die 3.In injection machine installation mold 3
When, Correction Die 3 is directed at the location hole of injection machine, it is easy to directly knock the flange 2 on mould 3, and flange 2 is direct with main filling
The body contacts of nozzle 1 are positioned, and collision rift is easily damaged to main filling nozzle 1, cause the main filling thread looseness of nozzle 1, there is leak adhesive risk.Main filling nozzle
Close to heating circle end face, flange 2 is directly contact positioning with main filling nozzle 1 to 1 temperature-sensing element, can take away partial heat, is caused
Plastic cement from molten condition injection come in when, nozzle position shear heat is excessive, easily cause plastic cement decomposition, in turn result in hot-fluid
The phenomenon generation that the product of road system processing has jaundice, blacks.
The content of the invention
It is an object of the invention to overcome above-mentioned weak point of the prior art, and provide a kind of hot flow path heat-insulating type method
Blue structure.
The present invention is achieved through the following technical solutions：Hot flow path heat-insulating type flange arrangement, including main filling nozzle and flange,
Also include heat insulation cap mold insert, heat insulation cap mold insert is padded in the annular groove in flange, jump ring is by heat insulation cap mold insert, main filling nozzle and flange
It is connected as one is overall.
Described heat insulation cap mold insert is plastic material.
The present invention is plastic material due to heat insulation cap mold insert, when installation mold is collided, can alleviate flange and directly make
For the power on main filling nozzle, play a part of the main filling nozzle of protection, heat insulation cap mold insert avoids main filling nozzle and flange directly contact, effectively
The loss of heat transfer is reduced, the shear heat of the plastic cement inside main filling nozzle is reduced, makes needle temperature control more accurate.
Brief description of the drawings：
Accompanying drawing 1 is by located by prior art structural representation；
Accompanying drawing 2 is schematic structural view of the invention；
Accompanying drawing 3 is flange and heat insulation cap insert structure figure.
Specific embodiment：
See accompanying drawing 2~3, hot flow path heat-insulating type flange arrangement, including main filling nozzle 1 and flange 2, it is heat-insulated also including heat insulation cap mold insert 4
Cap mold insert 4 is padded in the annular groove in flange 2, and be connected as one is overall for heat insulation cap mold insert 4, main filling nozzle 1 and flange 2 by jump ring 5.
Described heat insulation cap mold insert 4 is plastic material.
During using the present invention, when normally injection, the plastic cement of molten condition is injected into mould by hot flow path by main filling nozzle 1
In tool 3, because heat insulation cap mold insert 4 is padded in the annular groove in flange 2, and main filling nozzle 1 is separated with flange 2, effectively hindered
Break by the heat transfer between main filling nozzle 1 and flange 2, reduced the shear heat of the plastic cement inside main filling nozzle, made needle temperature control more
Accurately, it is to avoid the product jaundice of TOP-TIP processing, the phenomenon for blacking are produced.
Claims (2)
1. hot flow path heat-insulating type flange arrangement, including main fill nozzle and flange, it is characterised in that：Also include heat insulation cap mold insert, it is heat-insulated
Cap mold insert is padded in the annular groove in flange, and be connected as one is overall for heat insulation cap mold insert, main filling nozzle and flange by jump ring.
2. hot flow path heat-insulating type flange arrangement according to claim 1, it is characterised in that：Described heat insulation cap mold insert is modeling
Glue material.
