Description

Shaping mould for multi-purpose pulp fruit-tray

The utility model relates to and make the many a kind of shaping dies of paper pulp with the hypocarp dish.

The packing of the transport and storage of fruit in the past adopts tray formula hypocarp dish, this pallet is because superficial and shape is also fairly simple, so processing and manufacturing is more convenient, in the process of producing paper pulp hypocarp dish, because shallow, demoulding ratio is easier to after shaping, thereby the lay wire of absorption usefulness is shaped fairly simple, but adopt the effect of its transport and storage of tray packing fruit undesirable, only adapt to the thick packing of pericarp at present, be afraid of that for most of pericarp is thin the fruit of pressurized is just inapplicable as apple.

The purpose of this utility model is to design a kind of paper pulp at the weak point that above-mentioned tray formula fruit tray exists to use the hypocarp disk molding die more, adopts splicing structure, makes model manufacturing technique and metal lay wire processing technology simple, is convenient in demoulding, and adapts to and produces in batches.

The many shaping dies with the hypocarp dish of paper pulp take following mode to realize: this shaping dies is to produce the many particular manufacturing crafts with the hypocarp dish of paper pulp, has upper and lower mould.Primary structure is by upper mould fixed plate, and patrix shifts mould, goes up die support punch insert, metal lay wire, the counterdie forming board, and following moulded board, low mold frame, the counterdie punch insert, following die support die plate insert, the counterdie air chamber is formed.Counterdie forming board, counterdie punch insert, following die support die plate insert is used for vacuum suction paper pulp, therefore bored many apertures above, be cellular, its surface has been equipped with 30～60 purpose metal lay wire filtrations the same with its geometry, during vacuum suction, water is taken out and the paper fibre contracts and is adsorbed on the surface, and 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, and low mold frame is used for fixing counterdie forming board and counterdie die plate insert.

The utility model using method: produce the many pulp mold formed production equipments that special use must be arranged with the hypocarp dish of this kind paper pulp.Earlier patrix is screwed on the upper mould fixed plate, and then by on the patrix that installs to forming machine, again with counterdie by installing, refill on the lower bolster of forming machine, the upper and lower mould matched moulds is adjusted into the gap, and counterdie is fixed, mould finishes by dress.The forming machine sizing compartment flows into and cooperates certain density paper pulp, after opening vavuum pump and treating that vacuum meets the requirements of numerical value, just begin to produce, at first be to utilize the cylinder on the forming machine that counterdie is sunk to the machine sizing compartment, inhale slurry, treat that paper pulp on the mould is drawn onto the about moisture content of certain humidity about 70% with regard to the upper and lower mould matched moulds, the logical compressed air of counterdie upwards blows, the upwards suction of the logical vacuum of patrix, to patrix, counterdie descends with the transferred product of hygrometric state, after leaving patrix, receiver is put into patrix below, and the logical compressed air of patrix blows on the receiver with the hypocarp dish product one paper pulp is many, be a production cycle like this after, procedure auto-control is all adopted in recirculation, the hygrometric state pallet of producing pushes baking oven with dolly, adopts steam drying, promptly obtains desired product.Adopt many coiling of paper pulp of this mould production can be used to pack multiple fruit with hypocarp, and fragile article, be convenient to transport and storage.

The many die design with the hypocarp dish of paper pulp are rational in infrastructure, and long service life adopts splicing structure, makes mold production process simple, and the metal die processing technology is also simple, is convenient in demoulding, and adapt to and produce in batches.

The utility model is described in further detail below with reference to accompanying drawing:

Shifting mould (2) with reference to the many shaping dies primary structure patrixes with the hypocarp dish of accompanying drawing paper pulp by upper mould fixed plate (1) patrix constitutes, patrix shifts mould (2) and is fixed on upper mould fixed plate (1) bottom, and several are contained in last die support punch insert (4) on the patrix transfer mould (2).Upwards suction of the logical vacuum of patrix during work, hygrometric state paper pulp hypocarp dish (3) is transferred to patrix and is shifted on the mould (2).Counterdie is mainly by counterdie forming board (7), following moulded board (8), low mold frame (9), counterdie air chamber (10) constitutes, counterdie forming board (7) adopts set bolt (12) to be fixed on the low mold frame by following moulded board (8), and counterdie punch insert (5) is arranged according to certain rules and is fixed on the low mold frame.Counterdie air chamber (10) is contained in the low mold frame bottom.Following die support die plate insert (11) is fixed on the counterdie forming board (7).Metal lay wire (6) is installed in counterdie punch insert (5), the surface of following die support die plate insert (11).Be half garden sphere with reference to accompanying drawing 3,4 counterdie punch inserts (5), it is the main shaped portion of mould, bore some apertures (10) above it and be porous state, work the usefulness of drawing water, there are one deck and the living metal lay wire of punch insert (6) filtration in the surface, 4 convex tendons (15) are arranged above the punch insert, and there is a convex (13) at the center, and its effect is to form paper pulp how to take inventory the cavity of putting fruit with hypocarp.Following die support die plate insert (11) be as form the many supportings with the hypocarp dish of paper pulp with above be processed with some apertures (14) (accompanying drawing 5,6).Accompanying drawing 7,8 counterdie forming boards (7) are processed with the hole (16) that is used to install the counterdie punch insert, the stepped hole (17) of die support die plate insert down is installed, it is many with housing reinforcement formation place (18) of hypocarp dish also to have paper pulp, pallet attacker shaping place (19), and hand is taken part when being used to place fruit.
