Description
Technical field
The utility model relates to bottle embryo processing unit (plant) fields more particularly to a kind of bottle embryo to process multilayer hot runner mould.
Background technique
As current PET bottle is in the extensive use of the packaging industries such as food, beverage, the requirement to PET bottle is higher and higher.
The advantages that PET has very strong tensile ductility, toughness, is not easily broken, non-breakable, is easy molding.But also there is gas retaining poor
The shortcomings that.When filling the liquid beverages such as milk, beer, CO2 is easy to reduce, so that the shelf-life is very short.It is asked to solve this
Topic needs that one layer of good material of barrier property is added among the wall thickness of bottle.Such as nylon.It is just needed before bottle molding
Barrier material is added in bottle embryo, blows bottle together, just can guarantee the uniformity of wall thickness, other physical properties such as ductility.
Hot runner mould has injection efficiency height, molding plastic part quality good and saves raw material compared with common flow passage mold
The advantages that, with the development of polymer industry, Hot runner Technology is just constantly developing perfect, and application range is also increasingly wider
It is general.Hot flow path is to guarantee that the plastics of runner and cast gate are kept molten by by the method for heating.Due near runner or
Center is equipped with heating rod and heating coil, and the entire runner for exporting to cast gate from injection molding machine nozzle makes runner all in the condition of high temperature
In plastics keep melting, do not need to open runner after shutdown generally and take out condensate, then while being switched on only needs heating flow channel to required
Temperature.
It is, in general, that hot runner system is divided into single head hot runner system, bull hot runner system and valve gate hot flow path
System.Single head hot runner system is mainly made 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 molding machine injection nozzle connecting plate, nozzle head is reached through nozzle
Afterwards, injection type chamber.Bull hot runner system plastic mould structure is more complex.Molten plastics are connected by injection molding machine injection nozzle
Plate reaches nozzle head after hot runner manifold flows to nozzle, is then injected into type chamber.Valve gate hot runner system plastic mould structure is most
It is complicated.It and common bull hot runner system the modern designs of plastics structure having the same, in addition more a set of needle transmission device control
The open and close of needle processed moves.The transmission device is equivalent to a hydraulic cylinder, is connected using the hydraulic device and mold of injector
It connects, forms hydraulic circuit, realize the open and close movement of needle, control molten condition plastics injection type chamber.
The patent of invention that number of patent application is 201610547915.3 discloses a kind of hot runner mould with double-layer channel
Tool, including flow passage plate structure；The flow passage plate structure includes transition plates and air cylinder board；Between the transition plates and the air cylinder board
Equipped with the first surface layer runner plate and the first sandwich layer runner plate；The inside of first surface layer runner plate is equipped with the first surface layer melt dividing；
The first sandwich layer melt dividing is equipped in first sandwich layer runner plate；The second subsurface runoff is equipped between the transition plates and the air cylinder board
Guidance tape and the second sandwich layer runner plate；The second surface layer melt dividing is equipped in second surface layer runner plate；It is set in second sandwich layer runner plate
There is the second sandwich layer melt dividing.The present invention is designed using double-layer channel, i.e., surface layer melt dividing, which is equipped with, can be realized independent temperature control
Double-layer channel；Sandwich layer melt dividing also is provided with can be realized the double-layer channel of independent temperature control, can be simultaneously by different meltings
Hierarchically injection type chamber, realization inject different materials in the same bottle embryo higher slice to shape plastics.
But aforesaid way is only able to achieve the double-deck melt injection molding, cannot achieve three layers and the perfusion of the above melt.The width of runner
Degree is fixed always, then after surface layer melt pours into runner, surface layer melt can be led with the sandwich layer melt mutual extrusion in runner
The case where causing surface layer melt to mix with sandwich layer melt.When the melt number of plies increase for needing to be perfused, between multilayer melt more
It is easy to appear mixing.It is based on the above reason, above-mentioned apparatus cannot achieve the perfusion of three layers of above melt of machine.
