Description

A kind of wood plastics tray compression moulding die
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.

The cope plate upper end is provided with cast entrance, and cast entrance is communicated with the material chamber in cope plate, the material chamber Lower end is provided with several branches cast channel, branch cast channel and the groove of cope plate lower end one-to-one correspondence and it is vertical communicate, Guide sleeve is provided in cope plate, guide sleeve is corresponding with guide post in the lower template of lower template component;Upper mold between the grooves Heating tube is provided in plate.
Lower template upper end is provided with guide post and groove I, groove I matches composition mould type with the lower face of cope plate Chamber;Several protrusions, protrusion and the groove match on cope plate are provided in groove I;It is set in lower template between bumps It is equipped with centre hole and heating tube, centre hole is corresponding with the thimble of ejection assembly;It is provided with for ejection assembly in lower mould bottom plate The through-hole passed through.
The application method of wood plastics tray compression moulding die is:First, under the action of press master cylinder, upper die component and lower module Part is molded and is locked along guide post guide sleeve direction;
Then, so that heating tube is heated, ensure the temperature of mold cavity;
Then, the melting wood moulding raw material for being plasticized and measuring is added to material intracavitary, pressure by feed device by charge door Auxiliary cylinders acting ram, makes plunger depression, and wood moulding raw material is poured into a mould by branch in the press-in die cavity of channel from material chamber;
Furthermore cooling, product molding solidification;
Finally, lower open die is acted in press master cylinder, thimble is solidifying by finished product and cast under the drive of press push rod and top plate Material ejection.
Injection moulding of the present invention is additionally provided with individually material chamber and is moulded to contain melting other than being capable of providing enough pressure Material, and pour into a mould channel by branch and squeeze molten plastic and be full of cavity, so that plastic melt is further plasticized and is sheared, fills Fill out that effect is more preferable, the product precision of production is high, can form apparent molecularly oriented, is beneficial to improve the intensity of moulded products.
For injection-compression molding special hydraulic press there are two hydraulic cylinder, a master cylinder mainly provides clamp force, and a secondary cylinder mainly carries Plunger is supplied for pressure, plastic melt is injected by mold cavity by plunger.The present invention can not only ensure that quality was cost-effective, but also It can solve Wood-plastic material formation problems.
