Description

Moulding die for making egg-tray made of pulp

The utility model relates to a kind of shaping dies of making Paper pulp box for eggs.

The packing of the transport and storage of egg in the past adopts the pulp mold egg pallet of 30 dresses; this pallet is owing to have certain elasticity and good intensity; can make egg play shockproof shatter prevention effect; compare with plastic pallet; can recycle pollution-free; protectiveness and resiliency with uniqueness with low cost; this pallet is because area big (30 dresses); and shape is fairly simple, so processing and manufacturing is more convenient, in the process of producing paper pulp egg pallet; the back demoulding ratio that is shaped is easier to; thereby the lay wire of absorption usefulness is shaped than being easier to, but employing pulp mold egg pallet, the egg of dress is many; it is open type; be only applicable to the transport and storage packing, can not solve inner wrapping problem in print, be unfavorable for that supermarket and family use.

The purpose of this utility model is a kind of Paper pulp box for eggs shaping dies that designs at the weak point that above-mentioned egg pallet exists, be suitable for the egg box shaping dies of producing 12 (or 10 or 6) dress, adopt splicing structure, make model manufacturing technique and metal lay wire processing technology simple, be convenient in demoulding, adapt to and produce in batches.

The shaping dies of pulp mold egg box takes following mode to realize: this shaping dies is a particular manufacturing craft of producing pulp mold egg box, has upper and lower mould to form.Primary structure is by patrix, patrix air chamber, low mold frame pressing plate, low mold frame, upper cover body, last cover core, loam cake piece, counterdie piece 1, and counterdie piece 2, folding build the counterdie air chamber, the metal lay wire is formed.Upper cover body, last cover core, counterdie piece 1, counterdie piece 2, folding lid is used for vacuum suction paper pulp, has bored many apertures above therefore, is cellular, its surface has been equipped with the 30-60 purpose metal lay wire of being close to surface consistent with its geometry, filtration, water is taken out and the paper fiber is adsorbed on the surface during vacuum suction, when being drawn onto certain thickness, moisture content is about 70% just can be shaped, do not damage after the demoulding, just become product after the drying, patrix plays demoulding effect, low mold frame is used for fixing upper cover body, counterdie piece 1, counterdie piece 2 and folding lid, the low mold frame briquetting determines the appearance and size of product and compresses counterdie.

The utility model using method: producing this kind pulp mold egg box pallet must have special-purpose pulp mold formed production equipment.Earlier be installed to patrix on the upper mould fixed plate of forming machine with screw, again counterdie is installed, refill on the lower bolster of forming machine, the upper and lower mould matched moulds is adjusted the die clearance, counterdie is fixed, mould installs, the machine sizing compartment of forming 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 cylinder on the forming machine that counterdie is sunk to the machine sizing compartment to inhale slurry and treat that it is about 70% with regard to the upper and lower mould matched moulds that paper pulp on the mould is drawn onto certain thickness and certain about moisture content of temperature, the logical compressed air of counterdie upwards blows, upwards suction of the logical vacuum of patrix simultaneously, the transferred product of hygrometric state is arrived patrix, counterdie descends, after leaving patrix, receiver is put into the patrix below, the logical compressed air of patrix is with product--and the egg box blows on the receiver, after being the production cycle that is shaped like this, recirculation, all processes adopts procedure auto-control, the hygrometric state egg box of producing pushes drying tunnel with dolly, adopt the steam heated-air drying, promptly obtain desired product, adopt the pulp mold egg box of this mould production to be mainly used in the packing of 12 eggs, be convenient to transportation and direct marketing.

The die design of pulp mold egg box is rational in infrastructure, and long service life adopts splicing structure, makes that mold production process is simple, metal lay wire processing technology is also simple, is convenient in demoulding, and adapts to and produces in batches
