Abstract
The utility model relates to a mould, which particularly relates to an energy saving heat press mould for pulp mould press process. The utility model comprises a heating upper mould, a wet ground paper, an air-permeable net and a heating lower mould. The utility model is characterized in that an air-permeable hole is also arranged on the heating lower mould. The utility model has the advantages of energy saving, no stick with net of products, easy demoulding, etc.
Description
The utility model relates to mould, the energy-saving hot pressing die in particularly a kind of pulp molding technology.
In the prior art, for the bigger pulp molding goods of gradient (as the paper mess tin), adopt the technology manufacturing of upper and lower hot-die wet pressing usually, when last hot-die presses down, pushed the l Water Paper base, moisture content a large amount of in the l Water Paper base are extruded out.Cause wherein some does not contact with hot-die, becomes steam, has produced pressure, and along the hole of gas-permeable nets other water that is extruded is out discharged; Moisture film and the hygroscopic water in the cell membrane that residue is adsorbed on fiber surface can not be extruded, and can only lean on upper and lower hot-die transmission of heat by contact, get rid of with the formation of steam, thereby reach dry purpose.But have power consumption, product glues net, problems such as demoulding difficulty.
The purpose of this utility model is exactly at above-mentioned the deficiencies in the prior art part, provides a kind of energy-conservation, the not sticking net of product, the energy-saving hot pressing die in the pulp molding technology of the demoulding easily.
The purpose of this utility model is achieved in that the energy-saving hot pressing die in a kind of pulp molding technology, and it comprises hot-die, l Water Paper base, gas-permeable nets, hot counterdie composition, it is characterized in that also being provided with on hot counterdie air-vent; Described hot counterdie is to make with the material of heat conductivility difference.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing or embodiment the utility model is described in further detail: hot patrix 1, l Water Paper base 2, gas-permeable nets 3, hot counterdie 4, air-vent 5.As shown in the figure, on hot counterdie 4, also be provided with air-vent 5; Described hot counterdie 4 is to make with the material of heat conductivility difference.During use; because hot counterdie is to make with the material of poor heat conductivity; and do not generate heat, the gas-permeable nets on the hot counterdie is to make with the nonmetallic materials of poor heat conductivity, makes those be extruded out; and can sharply do not heated by the water that gas-permeable nets flows to hot counterdie; gasification; hot counterdie can not absorb the intensification heat in the product drying process basically, has reduced the consumption of energy thus, is hot-die because of one again; one is cold mould; hot-die is fixed, and cold mould motion just can be used pipeline easily; adopt non-electrically heated mode heating mould; reduced cost, wooden in the l Water Paper base can be under the condition that high pressure and moisture content exist, appearanceization just under lower temperature; the clean phenomenon of glue; since product contact be one not high attached to temperature, do not generate heat the net on the poor again mould of thermal conductivity; so in product is heated up dry process; by this surface temperature rising and the slowest of net, the change temperature of lignin improves, and is higher than the temperature of hot pressing die; sticking net phenomenon can not take place, and is easy to mould is broken away from.
The utility model has following advantage compared to existing technology: energy-conservation, and the easily demoulding, product Sticky net is not simple in structure.
