Abstract
Many spirals hot runner heat is chewed, the utility model belongs to the technical field of the thermoplastic machining technique and specifically relates to indicate the many spirals hot runner heat is chewed at the thermoplastic machining in -process. Realize through following technical scheme: many spirals hot runner heat is chewed comprises hot runner, needle and hot nozzle, and hot nozzle sets firmly in the not end of hot runner 1, and in the centre bore of locating hot nozzle was inserted to the needle, hot nozzle protruding was stretched the end and be the round platform type, is equipped with the spiral hole around the periphery of the centre bore of hot nozzle, the export equipartition in spiral hole on the hot nozzle protruding round platform inclined plane of stretching the end. Hot nozzle on the spiral hole be more than more than two.
Description
Technical field
The utility model is related to thermoplastic processing technical field, refers in particular to a kind of many spirals heat during thermoplastic processing
The hot nozzle of runner.
Background technology
Hot flow path process technology is to ensure the plastics of runner and cast gate by the method for heating to be kept molten by carrying out
Injection.The existing needle-valve type hot nozzle 2 in the top of hot flow path 1 is as shown in accompanying drawing 1~3, and it is straight that its structure uses single hole
Enter plastic structure, if injection machine injection pressure is excessive, it is higher to go out cast gate plastic cement amount, excessive velocities, the plastic cement material high for degree of adhesion
Material, in the case of HTHP, the easy high shear of plastic produces shear heat, and jaundice, hair are produced in the gate location of product
Black phenomenon, this phenomenon is that the general of hot flow path industry has problem partially；Next to that concentricity it cannot be guaranteed that, each hot flow path 1 is molded
When, product is molded by single hole, the stroke of needle 3 is long, it is impossible to ensure the concentricity of its nozzle point position well, and
Needle and the end of hot flow path 1 are susceptible to continuous collision, go down for a long time, easily break needle 3 and the end of hot flow path 1；Moreover by
In single hole arrangements are used, glue is easily hidden in the end interstitial site of hot flow path 1 when product needs colour changing, be not easy inside hot flow path clear dry
Only.
The content of the invention
The utility model aims to overcome that above-mentioned weak point of the prior art, and provides a kind of many spiral hot flow paths
Hot nozzle.
The utility model is achieved by the following technical solution：Many spiral hot runner hot nozzles, by hot flow path, needle and heat
Nozzle is constituted, and thermal jet nozzle is fixedly arranged on the end of hot flow path, and needle is inserted in the centre bore of thermal jet nozzle, and the end that protrudes out of thermal jet nozzle is in
Circular platform type, threaded hole is provided with around the periphery of the centre bore of thermal jet nozzle, and the outlet of described threaded hole is distributed in thermal jet nozzle and protrudes out
On the round platform inclined-plane at end.
It is more than the threaded hole more than two on described thermal jet nozzle.
The utility model goes out plastic structure due to the direction of plastic plastic emitting is changed into spiral, and plastic cement is greatly reduced on the whole
Flowing velocity, reduces shearing force during plastic rubber shaping, while increasing the gel quantity of hot flow path end section so that done in client
The phenomenon that jaundice nigrescence occurs in gate location during white products is resolved；Concentricity is guaranteed, the structure of improved mistake,
Use side and enter plastic structure, needle stroke position shortens, hot flow path end fragment position serves positioning action to needle, while
Needle is not collided with hot flow path end section, and hot flow path accessory is protected well, extends the use of hot flow path accessory
Life-span；Due to using helical structure, for the client for requiring color replacing system, needle position sealing, helical structure sizing material can be along
The position in hole carries out plastic emitting, greatly reduces the presence of the Tibetan glue inside hot flow path, obtains the colour changing effect of hot flow path demand
Improve.
Brief description of the drawings：
Accompanying drawing 1 is the main sectional view of prior art；
Accompanying drawing 2 is the main sectional view of prior art thermal jet nozzle 2；
Accompanying drawing 3 is the side view of prior art thermal jet nozzle 2；
Accompanying drawing 4 is the utility model use state figure；
Accompanying drawing 5 is the utility model front view；
Accompanying drawing 6 is the utility model stereogram；
Accompanying drawing 7 is the utility model main sectional view；
Accompanying drawing 8 is the utility model side view.
Specific embodiment：
See accompanying drawing 4~8, many spiral hot runner hot nozzles are made up of hot flow path 1, needle 3 and thermal jet nozzle 4, and thermal jet nozzle 4 is fixed
In the end of hot flow path 1, needle 3 is inserted in the centre bore of thermal jet nozzle 4, and the end that protrudes out of thermal jet nozzle 4 is in circular platform type, around thermal jet
The periphery of the centre bore of nozzle 4 is provided with threaded hole 41, the outlet of described threaded hole 41 be distributed in thermal jet nozzle 4 protrude out end round platform it is oblique
On face.
It is more than the more than two of threaded hole 41 on described thermal jet nozzle 4.
The utility model greatly reduces plastic cement on the whole due to the direction of plastic plastic emitting is changed into the plastic emitting of threaded hole 41
Flowing velocity, reduces shearing force during plastic rubber shaping, while increasing the gel quantity of the end of hot flow path 1 section so that in client
The phenomenon that jaundice nigrescence occurs in gate location when doing white products is resolved；
Enter plastic structure due to using side, the travel position of needle 3 is shortened, the end fragment position of hot flow path 1 is played to needle 3
Positioning action, while needle 3 does not collide with hot flow path 1 end section, protects hot flow path accessory well, extends
The service life of hot flow path accessory；
Due to using helical structure, for the client for requiring color replacing system, the position seals of needle 3, helical structure sizing material can
Position along hole carries out plastic emitting, greatly reduces the presence of the Tibetan glue inside hot flow path 1, imitates the colour changing of the demand of hot flow path 1
Fruit is improved.
