Abstract
The utility model provides a prevent hot mouth of wire drawing, includes that hot mouth is personally experienced sth. Part of the body, hot mouth is sharp -tongued, prevents the wire drawing muzzle and prevent the wire drawing and inlay the needle, hot mouth position in the sharp -tongued upper portion of hot mouth, with hot mouth sharp -tongued inconsistent, sharp -tongued being located of hot mouth prevent the wire drawing muzzle inside, be located simultaneously hot mouth body lower part, with the hot mouth body with prevent that the wire drawing muzzle is inconsistent, the wire drawing muzzle of preventing be located hot mouth body lower extreme, with hot mouth body fixed connection, prevent the wire drawing inlay needle position in prevent the wire drawing muzzle inside, run through prevent the wire drawing muzzle. The utility model provides a pair of prevent hot mouth of wire drawing makes re zui sprue gate increase time, prevents the too big wire drawing phenomenon that leads to the fact of sprue gate center pressure, through inlaying the needle in the setting of the central point department of putting, can prevent that the pressure at sprue gate center is too big, can reduce the temperature at sprue gate through inlaying needle guide heat simultaneously to prevent the appearance of wire drawing.
Description
Technical field
This utility model is related to a kind of anti-wire drawing hot mouth.
Background technology
Hot flow path is different for the performance requirement of different types of plastic material and product in injection mo(u)lding.Wherein
When high transparency product is molded, may require that hot flow path bears the condition of high speed and high pressure.This require hot flow path hot mouth it is sharp-tongued go out
Glue hole accordingly increases, and also requires it is straight-through structure, because only that so can just make the product of molding occur without all kinds of problems.Such as
This can produce wire drawing phenomenon in formed product, for life because the expansion of hot mouth causes the pressure of mold center position to increase
The quality for producing product has a serious impact.
Utility model content
This utility model aims to provide a kind of anti-wire drawing hot mouth, and the pressure that can cause hot mouth center reduces, and prevents
The too high appearance so as to reduce wire drawing of equilibrium temperature at hot mouth.
To solve the above problems, a kind of anti-wire drawing hot mouth that this utility model is provided employs following technical scheme：
A kind of anti-wire drawing hot mouth, including hot nozzle body, hot mouth be sharp-tongued, anti-wire drawing muzzle and anti-wire drawing pin；Described hot mouth
Body is located at the sharp-tongued top of hot mouth, sharp-tongued inconsistent with described hot mouth；Described hot mouth is sharp-tongued positioned at described anti-wire drawing muzzle
Inside, while positioned at described hot nozzle body bottom, it is inconsistent with described hot nozzle body and anti-wire drawing muzzle；Described anti-wire drawing mouth
Set is located at described hot nozzle body lower end, is fixedly connected with described hot nozzle body；Described anti-wire drawing pin is located at described anti-drawing
Inside silk muzzle, through described anti-wire drawing muzzle.
Further, described hot mouth is sharp-tongued is provided with boss, and described boss is contradicted with described anti-wire drawing muzzle.
Further, female thread is provided with inside described hot nozzle body lower end, described anti-wire drawing muzzle is cylindrical to be provided with outer
Screw thread；Described female thread cooperates with external screw thread.
Further, described anti-drawing muzzle bottom is provided with sprue gate, and described sprue gate is with diameter greater than described hot mouth
Sharp-tongued diameter.
Further, described anti-wire drawing pin is located at described sprue gate center.
The beneficial effects of the utility model are：A kind of anti-wire drawing hot mouth that this utility model is provided causes hot mouth sprue gate
While increase, prevent that sprue gate center pressure is excessive to cause wire drawing phenomenon, by arranging pin in center position, can in case
Only the pressure at sprue gate center is excessive, while the temperature at sprue gate can be reduced by pin heat conduction, so as to prevent going out for wire drawing
It is existing.
Description of the drawings
Accompanying drawing 1 is the front view of this utility model preferred embodiment.
Accompanying drawing 2 is the left view of this utility model preferred embodiment.
Wherein：1. hot nozzle body, 2. hot mouth is sharp-tongued, 3. anti-wire drawing muzzle, 4. anti-wire drawing pin, 5. boss, 6. female thread, 7.

Specific embodiment
In order to be better understood upon the technical scheme of this utility model offer, below in conjunction with the accompanying drawings with specific embodiment pair
This utility model is described further.
As shown in drawings, a kind of anti-wire drawing hot mouth for providing for this utility model, including hot nozzle body 1, hot mouth is sharp-tongued 2, anti-
Wire drawing muzzle 3 and anti-wire drawing pin 4；Described hot nozzle body 1 is located at sharp-tongued 2 top of hot mouth, offsets with described hot mouth sharp-tongued 2
Touch, for whole hot flow path hot glue is transported；Described hot mouth sharp-tongued 2 is located inside described anti-wire drawing muzzle 3, while being located at institute
The bottom of hot nozzle body 1 stated, it is inconsistent with described hot nozzle body 1 and anti-wire drawing muzzle 3, for pouring into a mould hot glue；Described anti-wire drawing
Muzzle 3 is located at the described lower end of hot nozzle body 1, is fixedly connected with described hot nozzle body 1, is simultaneously described for increasing sprue gate
Pin 4 provides support；Described anti-wire drawing pin 4 is located inside described anti-wire drawing muzzle 3, through described anti-wire drawing muzzle
3, for reducing the center pressure of described anti-wire drawing muzzle 3, while cooling down its central temperature.
Further, described hot mouth sharp-tongued 2 is provided with boss 5, and described boss 5 is supported with described anti-wire drawing muzzle 3
Touch, fixed by described anti-wire drawing muzzle 3 and described hot nozzle body 1, described boss is withstood in described hot nozzle body 1
Portion, so as to the position of fixed described hot mouth sharp-tongued 2.
Further, female thread 6 is provided with inside the described lower end of hot nozzle body 1, described anti-wire drawing muzzle 3 is cylindrical to be provided with
External screw thread 7；Described female thread 6 cooperates with external screw thread 7, for connecting described hot nozzle body 1 and anti-wire drawing muzzle 3.
Further, the described anti-bottom of drawing muzzle 3 is provided with sprue gate 8, and described sprue gate 8 is with diameter greater than described heat
The diameter of mouth sharp-tongued 2, for providing bigger sprue gate to pour into a mould product.
Further, described anti-wire drawing pin 4 is located at the described center of sprue gate 8, it is ensured that described sprue gate 8
Center be not in wire drawing phenomenon.
