Description
Technical field
This utility model relates to a kind of nozzle arrangements.
Background technology
Along with current PE T (Polyethylene terephthalate) bottle is extensive the packaging industry such as food, beverage
Application, the requirement to PET bottle is more and more higher.PET has the strongest tensile ductility, toughness, is not easily broken, the most broken, holds
The advantages such as easy-formation.But the shortcoming also having gas retaining difference.When filling the liquid beverage such as milk, medicated beer, CO2It is easy to reduce, makes
Obtain the shelf-life 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.It was accomplished by bottle embryo adding barrier material, together bottle blowing, guarantee wall thickness uniform before bottle molding
Property, other physical property such as ductility.
Hot runner mould, compared with common flow passage mould, has that injection efficiency is high, molding plastic part quality is good and economizes in raw materials
Etc. advantage, along with the development of polymer industry, Hot runner Technology the most constantly develops perfect, and its range of application is more and more wider
General.Hot flow path is to ensure that the plastics of runner and cast gate are kept molten by by the way of heating.Due near runner or
Center is provided with heating rod and heating collar, exports to the whole runner of cast gate all in the condition of high temperature from injection molding machine nozzle, makes runner
In plastics keep melted, typically need not open runner after shutdown and take out solidifying material, then it is required only to need heating flow channel to arrive when starting shooting
Temperature.
It is, in general, that TOP-TIP is divided into single head TOP-TIP, bull TOP-TIP and valve gate hot flow path
System.Single head TOP-TIP is mainly made up of single-nozzle, nozzle head, nozzle connecting plate, temperature control system etc..Single head hot flow path
System mould of plastics structure is simpler.By molten condition plastics by injection machine injection nozzle connecting plate, arrive nozzle head through nozzle
After, inject die cavity.Bull TOP-TIP mould of plastics structure is more complicated.Molten plastics are connected by injection machine injection nozzle
Plate, arrives nozzle head after hot runner manifold flows to nozzle, is then injected into die cavity.Valve gate TOP-TIP mould of plastics structure is
Complicated.It has identical structure with common bull TOP-TIP mould of plastics, additionally more than a set of needle actuating device control
The open and close motion of needle processed.This actuating device is equivalent to a hydraulic jack, utilizes the hydraulic means of injector with mould even
Connect, form hydraulic circuit, it is achieved the open and close motion of needle, control molten condition plastics and inject die cavity.
The hot runner mould processing bottle embryo in prior art typically uses single layer flow path or double-layer channel, and nozzle arrangements
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
Tool, its shortcoming becomes apparent from, and runner is elongated, and difficulty of processing increases, and injection molding channel resistance 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, and aberration, burr, modification, material become fragile, degraded toughness
Etc. phenomenon.
