The utility model discloses the system combines with hot nozzle of needle valve formula and the hot nozzle of wire dot system with the hot runner, can enough carry out time schedule control through the hot nozzle of needle valve formula, reduces the injection pressure of mould, can avoid to form " sun circle " around the product advances a little through the hot nozzle of wire dot system again, the utility model discloses a design improves product quality, improves production efficiency.
Description
Technical field
It is related to injection molding art, particularly a kind of double sections of Hot nozzle injection molds.
Background technology
It is different with the form according to nozzle in TOP-TIP, generally can be divided into open hot nozzle, needle valve type hot nozzle,
The forms such as wire dot system hot nozzle, needle valve type hot nozzle enter glue mode have cast gate residual it is little, cast gate trace border is beautiful, can adjust product
Product outward appearance weld mark and multiple hot mouths can be realized with the control of time and order, be suitable for large-scale, higher to appearance requirement
Product, therefore we can usually select needle valve type hot nozzle in large-sized plastic rubber Design of Dies, but needle valve type hot nozzle is scarce
Point is that injection amount is big, and at product enters " solar coil " can be usually formed, and causes product appearance flaw.Wire dot system hot nozzle is with regard to energy
This problem is solved very well, and problem of appearance will not be produced at entering, but needle-valve type hot nozzle can not realize sequencing contro, therefore need
A kind of new hot nozzle of utility model is wanted, the double sections of nozzles that well can be combined needle valve with the advantage of wire dot system hot nozzle
Fusion techniques.
Utility model content
To solve the deficiencies in the prior art, the purpose of this utility model be by TOP-TIP and needle valve type hot nozzle and
Wire dot system hot nozzle is combined, and can either carry out sequencing contro by needle valve type hot nozzle, reduces the injection pressure of mould；And energy
Avoid to be formed " solar coil " around product enters by wire dot system hot nozzle；Design of the present utility model, improves product matter
Amount, improve production efficiency.
In order to realize above-mentioned target, this utility model is adopted the following technical scheme that：
Double sections of Hot nozzle injection molds, including：Hot flow path, the main filling mouth being placed on hot flow path, the gas being placed on hot flow path
Cylinder, is placed under cylinder and is connected to the thermal jet nozzle assembly of hot flow path；Thermal jet nozzle assembly composition has：It is connected to the needle valve of hot flow path
Hot nozzle, is connected to the wire dot system hot nozzle of needle valve type hot nozzle.
Aforesaid double sections of Hot nozzle injection molds, external screw thread and the wire dot system hot nozzle of the head of needle valve type hot nozzle
The female thread connection of afterbody.
Aforesaid double sections of Hot nozzle injection molds, thermal jet nozzle assembly has also been constituted：Wrap needle valve type hot nozzle and pin
The fixing pipe of point type hot nozzle.
Aforesaid double sections of Hot nozzle injection molds, also include：It is connected to the flow distribution plate of hot flow path.
Aforesaid double sections of Hot nozzle injection molds, also include：It is connected to the control assembly of cylinder.
Aforesaid double sections of Hot nozzle injection molds, control assembly composition has：The gas circuit of cylinder is connected to, gas circuit is connected to
Electromagnetic valve.
It is of the present utility model to be beneficial in that：This utility model provides a kind of double sections of Hot nozzle injection molds, this practicality
It is new to be combined TOP-TIP with needle valve type hot nozzle and wire dot system hot nozzle, can either be carried out by needle valve type hot nozzle
Sequencing contro, reduces the injection pressure of mould；Can avoid that around product enters the " sun can be formed by wire dot system hot nozzle again
Circle "；Design of the present utility model, improve product quality, improve production efficiency.
Description of the drawings
Fig. 1 is a kind of sectional view of embodiment of the present utility model；
Fig. 2 is a kind of structural representation of embodiment of this utility model control assembly；
Fig. 3 is a kind of structural representation of embodiment of this utility model thermal jet nozzle assembly；
The implication of reference in figure：
1 hot flow path, 2 main filling mouths, 3 cylinders, 4 needle valve type hot nozzles, 5 wire dot system hot nozzles, 6 female threads, 7 consolidate
Fixed tube, 8 flow distribution plates, 9 gas circuits, 10 electromagnetic valves.
Specific embodiment
Make specific introduction to this utility model below in conjunction with the drawings and specific embodiments.
Double sections of Hot nozzle injection molds, including：Hot flow path 1, the main filling mouth 2 being placed on hot flow path 1, is placed on hot flow path 1
Cylinder 3, be placed in cylinder 3 times and be connected to the thermal jet nozzle assembly of hot flow path 1.
Thermal jet nozzle assembly composition has：The needle valve type hot nozzle 4 of hot flow path 1 is connected to, the pin of needle valve type hot nozzle 4 is connected to
Point type hot nozzle 5.The external screw thread of the head of needle valve type hot nozzle 4 is connected with the female thread 6 of the afterbody of wire dot system hot nozzle 5；This
The connected mode of sample can realize that the sequencing contro entered to product a little can improve product appearance quality again.
In order to stably fix the position of two nozzles, thermal jet nozzle assembly has also been constituted：Wrap needle valve thermal jet
The fixing pipe 7 of mouth 4 and wire dot system hot nozzle 5.
Injection mold, also includes：The flow distribution plate 8 of hot flow path 1 is connected to, flow distribution plate 8 is placed under the plate of cylinder 3, plastic cement melts
Body is downward through by main filling mouth 2, is diverted in each hot nozzle by flow distribution plate 8, realizes many click-through glue.
Injection mold, also includes：It is connected to the control assembly of cylinder 3；Control assembly composition has：It is connected to the gas of cylinder 3
Road 9, is connected to the electromagnetic valve 10 of gas circuit 9.
Running of the present utility model is；Melt plastic cement is protected through hot flow path 1, hot flow path 1 by the method for heating
The plastic cement of card product is kept molten by, and makes melt plastic cement flow into needle valve type hot nozzle 4 under the effect of injection machine high pressure, passes through
Wire dot system hot nozzle 5, finally flows into mold cavity, completes the injection mo(u)lding of whole product.
This utility model, by hot nozzle before, makes double sections of nozzles into from the system of hot flow path 1 of complete set, that is, go up
It is wire dot system hot nozzle 5 to hold as the lower end of needle valve type hot nozzle 4, and in injection moulding process, the system of hot flow path 1 passes through high temperature, by plastic cement
Grain thawing switchs to molten condition, and melt plastic cement is flowed into again in needle valve type hot nozzle 4, and the needle-valve of each needle valve type hot nozzle 4 is by gas
Pressure or hydraulic pressure are individually controlled, and air pressure or hydraulic pressure drive the needle-valve in hot mouth to move up and down to adjust into the closure put and enter glue amount
Number, here it is described sequencing contro before.Sequencing contro can reduce the injection pressure of mould, adjust product weld mark and
Adjustment product appearance, improves production quality.But can be formed " solar coil " around product enters, wire dot system hot nozzle 5 due to
Enter a point less, it is less enter glue amount will not produce " solar coil " at entering, but wire dot system nozzle cannot carry out sequential control
System, it is impossible to which the other problems of product appearance are adjusted.Therefore needle valve is combined with the hot nozzle of wire dot system two, can be solved
More problems.
Ultimate principle of the present utility model, principal character and advantage has been shown and described above.The technical staff of the industry
It should be appreciated that above-described embodiment does not limit in any form this utility model, it is all by the way of equivalent or equivalent transformation
The technical scheme for being obtained, all falls within protection domain of the present utility model.
