[specific embodiment]
As shown in Figure 1, the plastic pencil mould comprises pencil-lead extruder 1, pencil-lead mould 2, coating mould 3 and at least one plastic extruder, be provided with centre bore 34 in the described coating mould 3 and extrude passage, pencil-lead mould 2 is connected the front end of pencil-lead extruder 1, the centre bore 34 of coating mould 3 is over against the outlet of pencil-lead mould 2, and plastic extruder is by extruding channel connection around the centre bore 34 of coating mould 3.Pencil-lead extruder 1 is with the raw material of graphite and mineral matter combination, by being extruded into pencil-lead.
As shown in Figure 1, the quantity of described plastic extruder is 3, be respectively first plastic extruder 41, second plastic extruder 42, the 3rd plastic extruder 43, described first plastic extruder 41, second plastic extruder 42, the 3rd plastic extruder 43 is extruded passage 31 by first respectively, second extrudes passage 32, the 3rd extrudes the periphery that passage 33 is communicated to centre bore 34, and first extrudes passage 31, second extrudes passage 32, the 3rd outlet of extruding passage 33 successively by after distribute forward, the angle of the central shaft of the central shaft of described first plastic extruder 41 and second plastic extruder 42 is 45 °, and the angle of the central shaft of the central shaft of second plastic extruder 42 and the 3rd plastic extruder 43 is 45 °.Adopt three-decker in design, to fully take into account the reasonability of structure, the die body part of inner, middle and outer layer runner (that is: first extrude passage 31, second extrude passage the 32, the 3rd and extrude passage 33) all adopts the cross section curve form, and on the circumference of mould, be provided with three groups for regulating the screw that uses, approach effect of uniform thereby guaranteed to coat each bed thickness.
As shown in Figure 2, the exit of described pencil-lead mould 2 is provided with and exports coaxial ceramic calibration sleeve 21, and the exit of described pencil-lead mould 2 also is provided with pressure tester 22 in the front portion of ceramic calibration sleeve 21.Because its raw material is special, wear-resistingly become the emphasis that must consider, thereby the calibration sleeve part material on pencil-lead mould 2 adopts wear-resisting uranium face pottery, and require material the runner face hard chrome plating polishing of process, to improve the service life of mould.And pottery not only has wear-resisting characteristic, the effect of also have insulation, lubricating.After material enters pencil-lead mould 2 by pencil-lead extruder 1 with the material of extruding, measure melt pressure, pass through wear-resisting ceramic calibration sleeve 21 again, finish the making of pencil-lead through pressure tester 22.
As shown in Figure 3, B in the coating mould 3, C, three feed interfaces of D join with first plastic extruder 41, second plastic extruder 42, the 3rd plastic extruder 43 respectively, the raw material that enters from the B mouth is interior layered material (major ingredient), the raw material that enters from the C mouth is middle material (a color material), and is outer layered material (glazing material) from the raw material that the D mouth enters.The front end of the centre bore 34 of coating mould 3 is provided with core rod 35, and the rear end of centre bore 34 is provided with mouthful mould 36.Also be provided with cooling deflector roll 37 on the coating mould 3, cooling deflector roll 37 is installed in the front portion of mouthful mould 36, and its effect is that the bar of mouthful mould 36 is tentatively cooled off, and guiding enters following bosh.
