The junction of main cast gate or hot flow path and stream road is known as into glue position；The main cast gate of panel far from mold into glue
Position is known as high drop into glue position, referred to as deep position；
Injection mold is usually forward direction into glue position, and because of article construction requirement, some injection molds must be set into glue position
It sets in the lateral of mold, lateral and deep position is referred to as side deep position into glue position；
Hot flow path is a kind of runner element of electric heating thermal insulation, and being divided to has directly-heated runner and two kinds of oblique hot flow path, usually positive deep
The mold of position into glue position is carried out using directly-heated runner into glue, and for the side deep position into the mold of glue position, the prior art is using oblique
Hot flow path is carried out into glue, refering to Fig. 3 and Fig. 4, compared with directly-heated runner, oblique hot sprue channel element it is expensive, and into glue shakiness
Fixed, installation maintenance trouble causes the processing and manufacturing cost of mold to increase, operation and maintenance cost increases, poor reliability, operational efficiency
Low, therefore, there is at high cost, low efficiency, poor reliability and deficiency in the prior art.
Summary of the invention
Aiming at the problems and shortcomings existing in the prior art, the utility model is used by into glue insert and directly-heated runner structure
At device, described into glue insert is block-like steel components, is equipped with into the inside of glue insert and is tilted to the right from top to bottom
Circular through hole is known as inclined flow passage；The directly-heated runner is the straight-through electric hot sprue channel element of needle valve；Cover half is fixed on into glue insert
Place, the upper end of the inclined flow passage are connect with the output end of directly-heated runner, and the lower end of inclined flow passage is connect with the side deep position；
When injection molding, by main cast gate, directly-heated runnerless injection go out fused solution plastic liquid through the inclined flow passage, side deep position,
Stream road, product sprue enter the die cavity surrounded by type chamber and type core, and after product molding, retention is in inclined flow passage, stream road and system
In product cast gate plastic liquid cooling and solidifying be cold burden head, after die sinking, dynamic model downwards with cover half parting, the top of the cold burden head
It is first extracted out downwards from the inclined flow passage into glue insert with dynamic model, later, cold burden head is all ejected by material head mandril upwards
It is detached from the technical solution of the type core of dynamic model, provides a kind of injection mold side deep position directly-heated runner simply into adhesive dispenser, it is intended to make side
Deep position achievees the purpose that reduce cost, improves efficiency, ensures reliability into the injection mold of glue.
Purpose of the utility model is realized as follows: a kind of injection mold side deep position directly-heated runner is simply into adhesive dispenser,
Including into glue insert, directly-heated runner, in which: described into glue insert is block-like steel components, is equipped with into the inside of glue insert
The circular through hole being tilted to the right from top to bottom is known as inclined flow passage；
The directly-heated runner is the straight-through electric hot sprue channel element of needle valve；
It is fixed at cover half into glue insert, the upper end of the inclined flow passage is connect with the output end of directly-heated runner, inclined flow passage
Lower end is connect with the side deep position.
Working principle and beneficial effect
When injection molding, by main cast gate, directly-heated runnerless injection go out fused solution plastic liquid through the inclined flow passage, side deep position,
Stream road and product sprue enter the die cavity surrounded by type chamber and type core, and after product molding, retention is in inclined flow passage, stream road and system
In product cast gate plastic liquid cooling and solidifying be cold burden head, after die sinking, dynamic model downwards with cover half parting, the top of the cold burden head
It is first extracted out downwards from the inclined flow passage into glue insert with dynamic model, later, cold burden head is all ejected by material head mandril upwards
It is detached from the type core of dynamic model.
The simple reliable operation of present apparatus structure, it is low in cost versatile, by realizing side into glue insert and directly-heated runner
Deep position the drawbacks of avoiding using oblique hot flow path, reduces costs side deep position into the injection mold of glue, improves effect into glue
Rate, it is ensured that the reliability of work.
Above-mentioned, the utility model is used by the device that constitutes into glue insert and directly-heated runner, it is described into glue insert be block
The steel components of shape are equipped with the circular through hole being tilted to the right from top to bottom into the inside of glue insert and are known as inclined flow passage；Described is straight
Hot flow path is the straight-through electric hot sprue channel element of needle valve；It is fixed at cover half into glue insert, the upper end of the inclined flow passage and directly-heated stream
The output end in road connects, and the lower end of inclined flow passage is connect with the side deep position；
When injection molding, by main cast gate, directly-heated runnerless injection go out fused solution plastic liquid through the inclined flow passage, side deep position,
Stream road, product sprue enter the die cavity surrounded by type chamber and type core, and after product molding, retention is in inclined flow passage, stream road and system
In product cast gate plastic liquid cooling and solidifying be cold burden head, after die sinking, dynamic model downwards with cover half parting, the top of the cold burden head
It is first extracted out downwards from the inclined flow passage into glue insert with dynamic model, later, cold burden head is all ejected by material head mandril upwards
Be detached from dynamic model type core technical solution, overcome the prior art there are problems that at high cost, low efficiency, poor reliability with not
Enough, a kind of provided injection mold side deep position directly-heated runner reaches side deep position into the injection mold of glue simply into adhesive dispenser
The purpose that reduces cost, improve efficiency, ensure reliability.
