Description
Technical field
The utility model belongs to Hot runner Technology field, sharp-tongued more particularly to a kind of new hot mouth.
Background technology
As the application of the hot flow path of plastic product is more and more extensive, the requirement of product property is also higher and higher, open
The surface defects of products that brings of hot flow path injection molding manner, it is impossible to meet the quality requirements of injecting products, therefore more injection moulds
Tool selects controllable needle valve type hot runner system to go to complete to be molded.Hot mouth is sharp-tongued in needle valve type hot runner system can be to needle
Play the role of guide-localization, sharp-tongued hot mouth is part vital in needle valve type hot runner system.Further, since plastics
The color of product and colour changing requirement, to prevent dead angle, hot mouth is sharp-tongued to be contacted it is generally necessary to open frame with mold, therefore Hot nozzle
The structure of point also directly influences the quality of plastic product.
There are many defects for the sharp-tongued structure of the hot mouth of needle valve type hot runner system at present.
For one with cast gate plane, mold is corresponding to be opened frame and is also one and put down with cast gate present Hot nozzle crack tip
Face, and the cast gate size that sharp-tongued cast gate opens frame with mold is identical.Since plastics need to be heated to by hot flow path
The state of melting, so the sharp-tongued temperature of hot mouth can be very high, and the flat face that sharp-tongued front plan opens frame with mold touches, sharp-tongued
Heat can pass on mode, and mode is contacted directly with product surface, is easily scalded which results in product surface, right
The quality of plastic product has a great impact.And due to the sharp-tongued expanded by heating of hot mouth, hot mouth is sharp-tongued easily to push up bad mould
Benevolence increases mold repair cost.
The content of the invention
In view of the deficienciess of the prior art, technical problem to be solved in the utility model is, needle valve can be solved
Hot mouth sharp-tongued the problem of being contacted with mold, product is caused to be scalded during Hot Runner System injecting products, and avoid due to Hot nozzle
Sharp expanded by heating and push up bad mold.
In order to solve the above technical problems, technical solution adopted in the utility model is：A kind of new hot mouth is sharp-tongued, including
Hot mouth body, it is sharp-tongued to be equipped with hot mouth in the hot mouth body cavity body, the hot mouth it is sharp-tongued by hot mouth pressure cap screw-threaded coupling in heat
In the cavity of mouth body, the hot mouth body is packed into that mold opens frame and hot mouth body opens the mating surface of frame with mold and connects, described
Hot nozzle crack tip is equipped with sharp-tongued arc surface, and the mold opens what frame front end was adapted equipped with the arc surface sharp-tongued with the hot mouth
Mold arc surface, the sharp-tongued arc surface are connected on a position with mold arc surface.
Above-mentioned new hot mouth is sharp-tongued, and the hot mouth body outer wall is cased with hot nozzle cannot heat device and limitation hot nozzle cannot heat device is slided
The heater baffle ring fallen, the hot mouth body are equipped with hot mouth temp.-sensing wire, further include the needle through hot mouth body, the needle one
End is sharp-tongued through valve needle cover, hot mouth, and the needle other end is placed in hot mouth bodies top and equipped with needle hanging platform, the needle
Hanging platform connects lever, and the lever connects driving cylinder, and the hot mouth bodies top is equipped with injection nozzle, the injection nozzle and hot mouth sheet
Sizing material runner is connected between body.
The Hot nozzle crack tip structure is changed to arc surface by plane, and corresponding mold opens frame and is also changed to arc surface by plane,
The face of the prior art contacts the contact that can transform to point-to-point by changing the sharp-tongued shape with opening frame with face, can effectively prevent
Sharp-tongued heat is passed in mode.
The advantages of new hot mouth of the utility model is sharp-tongued be：
1st, the new hot mouth of the utility model is sharp-tongued, and hot mouth is sharp-tongued to be connected to each other with hot mouth body using the sharp-tongued insertion hot mouth of hot mouth
The design in body runner hole it is possible to prevente effectively from runner dead angle, is conducive to product colour changing, has the quality of white products and substantially carries
It rises, and ensure that the positioning of the sharp-tongued circumferencial direction of hot mouth so that it can have better stability in the later stage.Hot nozzle
Crack tip and mold open the part that frame contacts and are designed as arc surface, increase the sharp-tongued wall thickness of hot mouth, possess it higher strong
Degree.It is also arc surface that corresponding mold, which opens frame, the contact of point-to-point can effectively prevent hot mouth it is sharp-tongued on heat be transmitted to mold
In, the problem of can preventing cast gate cold burden, being also prevented from Hot nozzle pinnacle bad mode, scalded to product surface, which also has, substantially to be changed
It is kind.This structure is easy to install, easy to process, and stability is high, and service life is long.
2nd, the new hot mouth of the utility model is sharp-tongued, and hot mouth pressure cap uses the better material of thermal conductivity, can be by hot mouth
Heat on body, hot nozzle cannot heat device is as much as possible be transmitted to hot mouth it is sharp-tongued in, which can prevent stream in Hot nozzle
Cold burden is generated in point.Hot mouth pressure cap surface increases electroplated layer, not only specious, can also avoid surface oxidation in use.
