Description
Technical field
The present invention relates to a kind of nozzle arrangements.
Background technology
As current PE T (Polyethylene terephthalate) bottle is extensive the packaging industries such as food, beverage
Using the requirement more and more higher to PET bottle.PET has very strong tensile ductility, toughness, is not easily broken, non-breakable, holds
The advantages that easy-formation.But also there is the shortcomings that gas retaining difference.When filling the liquid beverages such as milk, beer, CO2It is easy to reduce, makes
It is very short to obtain the shelf-life.In order to solve this problem, it is necessary to add one layer of good material of barrier property among the wall thickness of bottle.
Such as nylon.Just need to add barrier material in bottle embryo before bottle shaping, bottle blowing, just can guarantee that the uniform of wall thickness together
Property, other physical properties such as ductility.
Hot runner mould has injection efficiency height, shaping plastic part quality good and saves raw material compared with common flow passage mould
The advantages that, with the development of polymer industry, Hot runner Technology is just constantly developing perfect, and its application is also more and more wider
It is general.Hot flow path is to ensure that the plastics of runner and cast gate are kept molten by by the method for heating.Due near runner or
Center is provided with heating rod and heating collar, and the whole runner for exporting to cast gate from injection molding machine nozzle makes runner all in the condition of high temperature
In plastics keep melting, shut down it is latter as need not open runner and take out condensate, then heating flow channel is only needed when starting shooting to required
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 plastic mould structure is simpler.By molten condition plastics by injection machine injection nozzle connecting plate, nozzle head is reached through nozzle
Afterwards, die cavity is injected.Bull TOP-TIP plastic mould structure is more complicated.Molten plastics are connected by injection machine injection nozzle
Plate, nozzle head is reached after hot runner manifold flows to nozzle, is then injected into die cavity.Valve gate TOP-TIP plastic mould structure is most
It is complicated.It has identical structure with common bull TOP-TIP the modern designs of plastics, more in addition a set of needle transmission device control
The open and close motion of needle processed.Equivalent to one hydraulic jack of the transmission device, connected using the hydraulic means and mould of injector
Connect, form hydraulic circuit, realize the open and close motion of needle, control molten condition plastics injection die cavity.
The hot runner mould for processing bottle embryo in the prior art typically uses single layer flow path or double-layer channel, and nozzle arrangements
A kind of plastics can only be individually molded.Product structure is single, and product mechanical and physical performance out is poor.And for the mould of multi-cavity
Tool, its shortcoming become apparent from, and runner is elongated, and difficulty of processing increase, injection molding channel resistance is big, and plastics temperature variation is big so that
Homogeneity of product is poor, and product physical property is poor, often there is that note is discontented, aberration, and burr, modification, material become fragile, degraded toughness
Phenomena such as.
