Abstract

The utility model relates to a paper pulp moulding mould, which is provided with a mould body 1. Transversal and longitudinal direction ordered arrangement holes 2 are arranged on the mould body 1. The mould body is stiff, and the manufactured products are easy to demould. The high-strength paper pulp moulding manufactured products of complex geometric shape, such as a cylinder shape, etc., can be quickly produced. The serial products, such as a yarn axis, a paper cup, etc., can be exploited and produced. The utility model can also be used for the production of one time fast food boxes. The produced fast food boxes have heat shielding bottom margins, and the process of edges cutting is not needed.

Description

The paper mould formation mould

The utility model relates to a kind of mould of making moulded paper pulp product, especially a kind of moulded paper pulp product forming mould that is used for.

" paper mould " is one of new environmental protection industry of rising.At present, the paper mould production technology has two kinds basically, a kind of is to apply on mould with wire netting, by preformed behind the vacuum suction slurry, after the wet demoulding of moulding or to enter that the drying box inner drying becomes product or be dried to moisture content be behind about 30% the wet base, typing again, and carry out becoming product after the redrying; Another kind is ripe relatively disposable snack box production technology, it is the shape that is pressed into product with wire netting, surface sprinkling spreading mass moulding at woven wire, the woven wire that sprays spreading mass is inserted dry, the stripping metal net of typing in the heated mold as transfer mold, form product through the side cut operation.Characteristics such as moulded paper pulp product is recyclable with it, easy degraded are firmly got people's favor, but, present moulded paper pulp product is limit by production technology, can only produce product such as simple shape such as egg holder, back yard industry packing material, disposable snack boxes, for the complicated a little product of shapes such as tubular, just can not come out with paper mould, thereby limit applying of moulded paper pulp product, and cause this restriction key promptly be the formation mould problem of moulded paper pulp product.Apply the net forming mould owing to be the wet demoulding, determined it can not produce the complicated a little products of shape such as tubular; And the woven wire formation mould, because the firmness of silk screen is not high, the product that shapes such as tubular are complicated a little then can't be peeled off out from the woven wire formation mould, therefore also can't produce the complicated a little products of shape such as tubular.

The purpose of this utility model provides a kind of paper mould formation mould of producing complex-shaped moulded paper pulp product such as tubular.

Technical solution of the present utility model is: a kind of paper mould formation mould is provided with die body 1, the hole 2 that die body 1 is provided with laterally, vertically arranges in order.

Described die body 1 thickness is 0.2-1mm.

The base material of described die body 1 can be steel or iron or copper or aluminium.

Described hole 2 vertical, horizontal spacings are 0.5-5mm.

The aperture in described hole 2 is 0.2-1mm.

Described die body 1 can be vertical two parts of being fixed by jig 3.

The utility model has overcome deficiency of the prior art, die body is well-pressed, the easy demoulding of goods, realize the typing of paper pulp moulding product with the utility model, can produce the strong pulp moulding article of complicated geometirc physiques such as tubular fast, can Development and Production go out series of products such as yarn axis, dixie cup, also can be used for the production of disposable snack box, the mess tin of producing with its moulding can have heat insulation base, body is attractive in appearance, intensity is high, and the operation of need not cutting edge.The utility model is improved the paper mould technology, has widened production field, has strengthened market development dynamics, has social benefits such as high economic benefit and environmental protection.

Fig. 1 is the schematic diagram of the utility model embodiment.

Below in conjunction with drawings and Examples the utility model is further described.As shown in Figure 1: die body 1 can be selected the metallic plates such as steel plate, iron plate, copper coin or aluminium sheet of 0.2-1mm for use, and laterally, vertically interlocking by the spacing of 0.5-5mm on metallic plates such as steel plate, iron plate, copper coin or aluminium sheet stamps out the hole 2 that the aperture is 0.2-1mm.Again with holes 2 die body 1 is struck out the shape of product that will produce by mould.For the better demoulding, with holes 2 die body 1 vertically can be divided into two parts, block with jig 3 when absorption sizing material forming and typing, during the demoulding, open jig 3, whole formation mould is divided into two, be convenient to the demoulding.

Concrete operations technology is: embodiment described in the utility model is placed in the vacuum tank, vacuumize after again vacuum tank being put into slurry pool, control time makes the quantitative pulp material of this formation mould surface absorption, the formation mould that applies pulp material is inserted forced exhaust in the shaper, draining, dryness finalization as transfer mold, formation mould is taken out in the typing back, and the demoulding gets final product.
