Description
Technical field
The utility model belongs to pallet field shaping technique, and in particular to a kind of wood plastics tray compression moulding die.
Background technology
Pallet, especially large and medium-sized pallet can be used to store, load, transport goods, and being must not in Modern Materials Circulation storage
One of the logistics equipment that can lack.Wherein Wooden tray because its material resources it is limited, be easy the reasons such as humidity of damaging by worms, do not meet intelligence
The demand of manufacture.And plastic pallet is widely used in enterprises circulation because its appearance is beautiful, unique properties, especially in intelligence
Using more in capable of storing in a warehouse.
At present there are mainly two types of the production methods of plastic pallet, one is corresponding proximate matter is squeezed out by extrusion molding, then
It cuts again and is assembled into pallet, corresponding the process is more complicated, and tray form is single, and assembly intensity is unstable.Another is primary
It is molded pallet, but because plastic pallet size is larger, it is complicated, it is injection moulded the raw material used and process costs is higher, it is difficult to
It promotes.Therefore Wooden tray accounts for 90% in pallet market at present, and plastic pallet only accounts for 8% or so, and the market share is less, therefore
The forming method of plastic pallet is improved, it is the main thought for promoting plastic pallet development to reduce production cost.
Wood plastic composite refers to useless using common plastics and wood powder, stalk etc. such as polyethylene, polypropylene and polyvinyl chloride
The organic composite material mixed of plant fiber.Wood-plastic material advantage is mainly manifested in waterproof, moisture-proof and insect prevention, it is pollution-free can
It recycles, high fire line, be not cracked expansion, and cost is relatively low, but its molding has apparent defect, is exactly its mobility
It is insufficient, it is easy to short, especially one-pass molding large scale wood plastic product.Solution to this problem is mainly at present
Injection pressure, injection speed and clamp force are improved, process costs are higher, and energy consumption is larger, more demanding to former.And
When product is larger, it is easy to occur it is short penetrate, forming it is imperfect.
For plastic shaping, pressure directly acts on plastics for compression forming, and the pressure loss is small, and plastics are easy to fill
It fills out, mould structure is simple, relatively low to former requirement, but molding cycle is long, low production efficiency, the product strength of production
It is low, it is difficult to produce complicated plastic products.Moulding plastics pallet is mainly used in the not high small sized product of intensity requirement at present.
Invention content
