Abstract
The utility model discloses an extrusion die for plastic plates, which comprises an upper die plate, a lower die plate and a die frame positioned between the upper die plate and the lower die plate. The extrusion die is characterized by further comprising a first heat-insulation plate, an upper die core plate, a second heat-insulation plate and a lower die core plate, the first heat-insulation plate and the upper die core plate are positioned between the upper die plate and the die frame, the second heat-insulation plate and the lower die core plate are positioned between the lower die plate and the die frame, and the upper die core plate, the lower die core plate and the die frame fittingly form a forming channel. According to the technical scheme, the extrusion die is provided with the heat-insulation plates, accordingly, after the extrusion die for plastic plates is heated by the aid of a heating pipe, heat can be maintained for a longer time so that plasticizing of a plate to be extruded is maintained, and effect of energy conservation and electricity economization is achieved.
Description
Technical field
The utility model relates to mould applications, particularly a kind of plastic plate extrusion die.
Background technology
As shown in Figure 1; Existing plastic plate extrusion die mainly comprises: cope match-plate pattern 21 and lower bolster 22 and between cope match-plate pattern 21 and lower bolster 22 framed 23; They cooperate formation to supply to treat the cross-sectional passage of extrusion board moulding; Cope match-plate pattern 21 is respectively arranged with the heat-generating pipe 24 that runs through with lower bolster 22, and the extrusion board of treating that passes through is plastified.
The operation process is such: after the plastic raw materials of dried adds feed inlet barrel by the extruder hopper; Under rotation, compacting and the immixture of the temperature of barrel and screw rod; Be converted into the even melt with certain flowability by solid-state graininess or powdery, this melt moves to the front end of barrel with the rotation of screw rod then, under the effect of screw rod rotation extrusion; Form sheet material through the plastic plate extrusion die; At last, through typing and cooling device, make the sheet material hardening typing of coming out from the plastic plate extrusion die.
In continuous process engineering, need to continue the heating of switching on through 24 pairs of cope match-plate patterns of heat-generating pipe 21 and lower bolster 22, treat the plasticizing that extrusion board continues.Owing to lack thermal insulation layer on cope match-plate pattern 21 and the lower bolster 22; The heating heat that causes switching on is distributed through cope match-plate pattern 21 and lower bolster 22 in a large number; And then need to continue the energising heating through 24 pairs of cope match-plate patterns of heat-generating pipe 21 and lower bolster 22; Treat the plasticizing that extrusion board continues, cause waste of electric quantity.
The utility model content
The technical problem that the utility model solves provides a kind of thermal insulation board that has, the plastic plate extrusion die of energy saving.
For achieving the above object; A kind of plastic plate extrusion die that the utility model provides; Comprise: cope match-plate pattern and lower bolster and framed between cope match-plate pattern and lower bolster; Also comprise: cope match-plate pattern and framed between first thermal insulation board and patrix central layer, and lower bolster and framed between second thermal insulation board and counterdie central layer, patrix central layer, counterdie central layer and framed cooperation form shaping channel.
Further, first thermal insulation board and second thermal insulation board are heat-barrier material.
Further, first thermal insulation board and second thermal insulation board are asbestos board.
Further, framed is two block length battens, is positioned at the middle both sides of patrix central layer and counterdie central layer, two framed middle shaping channels that form.
Further, the heat-generating pipe of this plastic plate extrusion die is located in respectively in patrix central layer and the counterdie central layer.
Further, the cooling water channel of this plastic plate extrusion die is located in respectively in patrix central layer and the counterdie central layer.
According to the technical scheme of the utility model owing to have thermal insulation board, make this plastic plate extrusion die through the heat-generating pipe heating after, the plasticizing of treating extrusion board is kept in the maintenance that heat can the longer time, has reached the effect of energy saving.
Description of drawings
Fig. 1 is the structural representation of existing plastic plate extrusion die;
Fig. 2 is the structural representation according to the plastic plate extrusion die of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described in detail, but the protection domain that is to be understood that the utility model does not receive the restriction of the specific embodiment.
As shown in Figure 2; This plastic plate extrusion die comprises: cope match-plate pattern 1, lower bolster 3 and framed 5; Also comprise: thermal insulation board 11 and patrix central layer 12 between cope match-plate pattern 1 and framed 5, and thermal insulation board between lower bolster 3 and framed 5 31 and counterdie central layer 32; Between thermal insulation board 11 cope match-plate patterns 1 and the patrix central layer 12.Thermal insulation board 11 is a heat-barrier material with thermal insulation board 31, for example can adopt asbestos.The left end of patrix central layer 12 (left end among Fig. 2) is provided with heat-generating pipe 13, and right-hand member (right-hand member among Fig. 2) is provided with cooling water channel 14.Thermal insulation board 31 is between lower bolster 3 and counterdie central layer 32.The front end of counterdie central layer 32 (left end among Fig. 2) also is provided with heat-generating pipe 13, and rear end (right-hand member among Fig. 2) also is provided with cooling water channel 14.Framed 5 is two blocks of strip plates; Lay respectively at patrix central layer 12 and counterdie central layer 32 between the both sides, front and back; Side is along concordant with the corresponding front/rear end of patrix central layer 12 and counterdie central layer 32 respectively; Cope match-plate pattern 1, lower bolster 3, patrix central layer 12, counterdie central layer 32 is connected with framed 5 bolts through vertically (above-below direction among the figure) perforation, and framed 5 of patrix central layer 12 and counterdie central layer 32 and both sides cooperate formation shaping channels 51.
Add man-hour: after will adding feed inlet barrel by extruder (not shown) hopper through the plastic raw materials of dried earlier; Under rotation, compacting and the immixture of the temperature of barrel and screw rod, be converted into even melt by solid-state graininess or powdery with certain flowability, this melt moves to the front end of barrel with the rotation of screw rod then; Under the effect of screw rod rotation extrusion; Get into the left end of the shaping channel 51 of plastic plate extrusion die, at this moment, the further heating plasticizing of melt of 13 pairs of entering of heat-generating pipe of left end; Extrude formation sheet material from the right-hand member of shaping channel 51 then; Melt is set at the cold water cooling of circulation in the cooling water channel 14 in patrix central layer 12 and the counterdie central layer 32 in this process, and this sheet material has just had and this consistent cross section, shaping channel 51 cross sections, and the sheet material extrusion molding is accomplished.
According to the technical scheme of the utility model owing to have thermal insulation board, make this plastic plate extrusion die through the heat-generating pipe heating after, the plasticizing of treating extrusion board is kept in the maintenance that heat can the longer time, has reached the effect of energy saving.
More than a disclosed specific embodiment that is merely the utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into the protection domain of the utility model.
