Description

Paper pulp magazine clip pad moulding die

The utility model relates to a kind of shaping dies of making paper pulp magazine card pad.

Existing laser printer carbon powder magazine adopts polystyrene (ps) foam card pad to pack in transportation.This packing is owing to can not reclaim, disappear and generate the serious environmental pollution when ruining, so 12 countries of the European Economic Community have announced " new packing rule " in September, 91, came into effect new compulsory standard from 92 years, clearly announce transportation and packing, marketing packing forbidding polystyrene (ps) bubble wrap, replace with paper pulp moulded articles.

The purpose of this utility model is a kind of shaping dies of making paper pulp magazine card pad that designs at pertinent regulations, adopts splicing structure to make model manufacturing technique and metal lay wire processing technology simple, is convenient in demoulding, and adapts to and produces in batches.

The shaping dies of paper pulp magazine card pad takes following mode to realize: this shaping dies is a particular manufacturing craft of producing paper pulp magazine card pad, have upper and lower mould to form, primary structure is made up of patrix, upper mould fixed plate, patrix seal gasket, low mold frame pressing plate, low mold frame, counterdie piece 1, counterdie piece 2, counterdie piece 3, counterdie piece 4, lower mold body, counterdie fixed head, counterdie seal gasket, wire netting mould.Lower mold body, counterdie piece the 1,2,3, the 4th are used for vacuum suction paper pulp, have bored many apertures above therefore, are cellular.Its surface has been equipped with the 30-60 purpose metal lay wire of being close to surface the same with its geometry, play water filtering function, water is taken out and the paper fiber is adsorbed on die surface during vacuum suction, when being drawn onto certain thickness, moisture content is about about 70% and just can be shaped, do not damage after the demoulding, just become product after drying.Patrix plays demoulding effect, and low mold frame is used for fixing lower mold body and counterdie jigsaw 1,2,3,4, and the low mold frame pressing plate determines the appearance and size of product and compresses counterdie.

Using method of the present utility model: producing this kind paper pulp magazine card pad must have special-purpose paper pulp mold forming production equipment.Earlier patrix is fixed on the upper mould fixed plate, and then be installed to screw on the cope match-plate pattern of make-up machine, install on the lower bolster of make-up machine after again counterdie being installed, the upper and lower mould matched moulds is adjusted the die clearance, and counterdie is fixed, and mould installs, the machine sizing compartment of make-up machine flows into and prepares certain density paper pulp, open air compressor machine and vavuum pump, after the vacuum for the treatment of the pressure of air compressor machine and vavuum pump meets the requirements of numerical value, just begin to produce.At first be to utilize the cylinder on the make-up machine that counterdie is sunk to machine sizing compartment suction slurry, treat on the mould that paper pulp is drawn onto certain thickness and certain humidity if moisture content is about 70% with regard to the upper and lower mould matched moulds, the logical compressed air of counterdie blows to product card pad on the receiver, after being a forming period like this, recirculation, all processes adopts procedure auto-control, and the hygrometric state magazine card pad of producing pushes drying tunnel with dolly, adopts the steam heated-air drying promptly to obtain desired product.Adopt the paper pulp magazine card pad of this mould production to be mainly used in the packing of the 92295A of U.S. Hewlett-Packard laser printer carbon powder magazine, be convenient to transportation.

The die design of paper pulp magazine card pad is rational in infrastructure, and long service life adopts splicing structure, makes that mold production process is simple, the wire netting processing technology is simple, be convenient in demoulding, adapt to batch process.
