Description

Die set for moulding paper fibre tray

The utility model belongs to a kind of mould that is used to produce the mold-made paper fiber tray.

Be used for all kinds of article such as inner packing storing egg, fruit, bottled drinks and continue to use manila board checked spun antung packing in the past in packaging industry, loss is bigger.Reduce the wastage greatly with paper fiber tray inner packing in recent years, be convenient to long-distance transport and storage.Make egg pallet, apple pallet, pears pallet, bottle pallet and cleaning mat etc. and place all kinds of article pallets, key is mould.Existing domestic paper pulp moulding product is made mould therefor, mostly is to adopt casting fine finishining shaping unitary mould, needs the processing of high precision machine tool and main equipment.

The purpose of this utility model is to provide a kind of mould of all kinds of article paper fiber tray that are easy to make.

This mould is by main bone mould, silk screen mould and both are assembled into whole mould and stripper constitutes.Described main bone mould is to be combined into by little module weldering more than 2, and die face is the pallet formpiston that is suitable for placing all kinds of article, and is densely covered with pore; Described silk screen mould is to seal little mould by little mould of 2 above silk screens to form, and die face is woven into the silk screen hole; Above-mentioned silk screen mould and main bone mould are assembled into whole mould with bolt; Described stripper is and the mould of main bone mould precision-fit that die face is the pallet former corresponding with the pallet formpiston, also has the suction pore on die face.The hole diameter that gathers on this mould master bone mould die face can be 1mm, and every square centimeter can be 23 holes on the die face.

Mold-made paper fiber tray mould is reasonable in design, can be used on the dissimilar paper fibre mould machines, produces the pallet of placing all kinds of article; Stripper and main bone mould quality of fit are reliable, do not need the processing of high precision machine tool and main equipment, and manufacturing technique is simple, and the raw material source is wide; Do not have rib on the pallet formpiston of egg pallet, apple pallet, pears pallet, bottle pallet, help storing and transporting breakables; In addition, this mold weight is light, and cost is low, and the pallet that produces is not yielding, and aspects such as intensity, fragility, resistance to water all reach international like product QUALITY STANDARD.

Accompanying drawing 1～9th, the utility model egg pallet mould most preferred embodiment below is described in further detail.

With reference to Fig. 1～Fig. 4, main bone mould adopts with 6 little mould (1)

=0.8～1.2mm sheet copper, the intensive diameter 1mm pore (2) of stamping, every square centimeter 23 hole, through heat-treatment of annealing, repeatedly tension and compression are shaped unhairing limit assembly welding.Whole die face is processed with the pallet formpiston (4) of placing egg.With reference to Fig. 5～Fig. 7, the silk screen mould adopts stainless (steel) wire, and silk screen hole (6) are 40～60 orders, and blanking is drawn for 1～4 time through the frock mould with little moulds of 6 silk screens (5) tension and compression shaping and sealed little mould (1).With reference to Fig. 1, above-mentioned silk screen mould and main bone mould are assembled into whole mould with bolt (3).With reference to Fig. 8～Fig. 9, the making of stripper is with main bone mould absorption one deck paper pulp, casts on the paper pulp of well shaped with the resin glue for preparing after the artificial shaping, treats to bore after resin glue solidifies and goes up an amount of suction pore, and stripper is made.At this moment have the pallet former (7) corresponding with pallet formpiston (4) on the whole die face, egg is safe to be stored in the corresponding space, because pallet formpiston (4) is gone up no rib, egg is stored not easily broken, avoids loss.The utility model is loaded on the mould machine, the packaging production line of making paper pulp egg pallet is to utilize waste paper to blend pulping, make the paper pallet of storing egg through the whole mould shape that vacuum suction is dressed up according to this mould master bone mould, silk screen module, the effect of stripper is that the egg pallet that has been shaped is taken off and is placed on the dry conveyer belt from machine, plays the manipulator effect.The utility model designs pallet formpiston (4), pallet former (7) as required, can be used to make paper fiber tray such as apple pallet, pears pallet, bottle pallet and cleaning mat, crash roll.
