Description
Technical field
The invention belongs to pallet field shaping technique, and in particular to a kind of wood plastics tray and its pressure injection mold.
Background technology
Pallet can be used to deposit, load, transports goods, be Modern Materials Circulation storage in requisite logistics equipment it
One.Wherein Wooden tray because its material resources it is limited, the reason such as humidity of easily damaging by worms does not meet the demand of intelligence manufacture.And mould
Material torr disk because its outward appearance is beautiful, unique properties, be widely used in enterprises circulation, particularly in intelligent storage apply compared with
It is many.But at present Wooden tray accounts for 90% in pallet market, and plastic pallet only accounts for 8% or so, and the market share is less.Trace it to its cause
Plastic pallet complex structure is primarily due to, shot shaping is relatively costly, it is difficult to promote.
Plastic pallet has at present four kinds of molding modes：The first is injection molding method.The plastic pallet system of the method production
Product are smooth, bright and clean, well-pressed, closely knit, and the product design free degree is larger, are divided into double-side type integrated plastic pallet and double-side type assembling
Formula plastic pallet.Wherein double-side type integral tray common product is from focusing on more than 15 kilograms/block, and shape matching is complicated, it is desirable to
Injection machine production of the clamp force more than 2500 tons.Such pallet moulding is complicated, and investment is big, and cost is also higher, general plastics
Processing factory is using this method and few.Second is extrusion-hollow blow molding method.The method is blow molded with general hollow product
Forming method is similar, because its product is larger, and for double-side type, needs larger extruder, clapper die spotting press and mould etc..The third
It is vacuum suction moulding method.Method production shaping needs large-scale vacuum forming equipment, and cost of equipment is relatively low, die cost also compared with
It is low, but product wall unevenness is even.4th kind is extrusion moulding, and the plastic pallet of the method production is assembly type, product structure
Single, intensity is unstable.
Wood-plastic material（Wood-Plastic Composites, WPC）It is that the class being surging forward in recent years both at home and abroad is new
Composite.Refer to using polyethylene, polypropylene and polyvinyl chloride etc., replace common resin adhesive, and more than 35%-
The useless string such as more than 70% wood powder, rice husk, stalk is mixed into new wood materials.The advantage of Wood-plastic material is（1）Come
Source is enriched, with low cost.（2）It is waterproof, protection against the tide, insect prevention, termite-proof.（3）High-environmental, profit pollution-free, nuisanceless, capable of circulation
With.（4）High fire line.（5）Machinability is good.（6）It is not cracked, does not expand, it is indeformable.
But wood plastic product raw material are plastics+wood powders（35%-70%）+ coupling agent+other, mobility is very after melting
Difference, is limited by injection mold structure and injection machine injection pressure, injection speed and clamp force, when being molded larger product, wood moulding
Material is difficult smoothly to be full of die cavity.This problem is solved, at present mainly by raising injection pressure, injection speed and clamp force etc.
Taste improves the method for injection machine parameter solving, and cost blindly increases, and consumes energy larger.
Wood-plastic material is although with low cost, but it forms obvious defect, is exactly its illiquidity, it is easy to occur
Short, especially one-shot forming large scale wood plastic product.At present solution to this problem mainly improves injection pressure, note
Firing rate degree and clamp force, process costs are higher, consume energy larger, former required higher.And when product is larger, hold very much
Easily occur it is short penetrate, shape it is imperfect.
Injection transfer moulding method be low clamp force is applied to mould in the case of, first not completely closed mould, applies less
Injection pressure can just fill mold cavity, and then recompressing mould makes it close completely, carrys out moulded products.Injection moulding needs
The second-compressed of mould can be just completed using the injection machine for possessing secondary clamping apparatus, the equipment price is higher, be not suitable for owning
Injection factory.
The content of the invention
To be solved by this invention is that existing Wood-plastic material injection is difficult, and production cost is high, and cannot once be molded into
The technical problems such as the big-and-middle-sized wood plastics tray of type, injection mold price height, so as to provide a kind of injection pressure low cost, easy one-shot forming
