Description
Technical field
The present invention relates to a kind of hot runner mould, particularly relate to a kind of hot runner mould with double-layer channel.
Background technology
Along with current PE T (Polyethylene terephthalate) bottle is at the packaging industry such as food, beverage
Extensive application, the requirement to PET bottle is more and more higher.PET has the strongest tensile ductility, toughness,
It is not easily broken, the most broken, the advantage such as easy molding.But the shortcoming also having gas retaining difference.Dress milk,
During the liquid beverages such as medicated beer, CO2It is easy to reduce so that the shelf-life is the shortest.In order to solve this problem,
Need to add one layer of good material of barrier property in the middle of the wall thickness of bottle.Such as nylon.Bottle molding it
Before be accomplished by bottle embryo add barrier material, together bottle blowing, the uniformity of guarantee wall thickness, extend
Other physical properties such as property.
Hot runner mould, compared with common flow passage mould, has that injection efficiency is high, molding plastic part quality is good and saves
The about advantage such as raw material, along with the development of polymer industry, Hot runner Technology the most constantly develops perfect, and it should
More and more extensive by scope.Hot flow path is to ensure that the plastics of runner and cast gate keep by the way of heating
Molten condition.Owing near runner or center is provided with heating rod and heating collar, exporting to from injection molding machine nozzle
The whole runner of cast gate, all in the condition of high temperature, makes the plastics in runner keep melted, is typically not required to after shutdown
Runner to be opened takes out solidifying material, then it is temperature required only to need heating flow channel to arrive when starting shooting.
It is, in general, that TOP-TIP is divided into single head TOP-TIP, bull TOP-TIP and valve gate
TOP-TIP.Single head TOP-TIP is mainly by single-nozzle, nozzle head, nozzle connecting plate, temperature control system
The compositions such as system.Single head TOP-TIP mould of plastics structure is simpler.Molten condition plastics are noted by injection machine
Enter nozzle connecting plate, after nozzle arrives nozzle head, inject die cavity.Bull TOP-TIP mould of plastics is tied
Structure is more complicated.Molten plastics, by injection machine injection nozzle connecting plate, arrive after hot runner manifold flows to nozzle
Nozzle head, is then injected into die cavity.Valve gate TOP-TIP mould of plastics structure is the most complicated.It is with the most
Feverish sensation in the head flow passage system mould of plastics has an identical structure, additionally more than a set of needle actuating device control needle
Open and close motion.This actuating device is equivalent to a hydraulic jack, utilizes hydraulic means and the mould of injector
Tool connects, and forms hydraulic circuit, it is achieved the open and close motion of needle, controls molten condition plastics and injects die cavity.
The hot runner mould processing bottle embryo in prior art typically uses single layer flow path or double-layer channel, and sprays
Mouth structure can only individually be molded a kind of plastics.Product structure is single, and product mechanical and physical performance out is poor.
And for the mould of multi-cavity, its shortcoming becomes apparent from, and runner is elongated, difficulty of processing increases, and injection molding channel hinders
Power is big, and plastics temperature difference in change is different greatly so that homogeneity of product is poor, and product physical property is poor, often has note
Discontented, aberration, the phenomenon such as burr, modification, material become fragile, degraded toughness.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is an object of the invention to provide a kind of heat with double-layer channel
Runner mold, it uses double-layer channel design, i.e. top layer melt dividing to be provided with and is capable of the double of independent temperature control
Laminar flow road；Sandwich layer melt dividing also is provided with being capable of the double-layer channel of independent temperature control, it is possible to simultaneously by difference
