Abstract
The utility model relates to a micro-porous mold of an extruding machine, a moulding board is provided with a groove plane, and extruding pores are arranged on the groove plane. Both surfaces of the module can be provided with the same groove plane to ensure both surfaces to have the same using effects; all extruding pores are evenly arranged on the groove plane in a form of equilateral triangle. The utility model has the advantages that: kneading gaps are arranged on the moulding board to maintain the stability of the kneading gaps; both surfaces of the mold can be used, and the deformation tendency of the mold can be eliminated by changing the operation direction of the moulding board, and the impurities in the extruding pores can be conveniently removed; with the aid of the arranging manner of the extruding pores, materials can be smoothly extruded, thus enhancing the extruding efficiency.
Description
Technical field
The utility model belongs to the shaping of catalyst mould.
Background technology
The catalyst that is used for petroleum refining and petroleum chemical industry is made by extrusion (going out) machine.Extruder must supporting mould.For irregularly-shaped hole, there is not special matching die at present, all be self-control, on template, have the moulding hole.The desired shape of template and extruder is supporting, and the moulding hole is identical with required catalyst shape.As double screw extruder commonly used, when producing catalyst, mix as material between screw rod and template and pinch the gap, because the play of screw shaft can not guarantee the stable of gap, when template deformation, the gap has to increase to have and reduces.When the gap increased, it is slow that material goes out, easily dry in the moulding hole, stops up pattern hole; Gap hour, material have little time to mix and pinch, and make material inhomogeneous, can't guarantee the performance of catalyst.At this wherein, the one, template strength is low, easy deformation, and can't adjust; The 2nd, mix and to pinch the gap and can not keep stable; The 3rd, the moulding hole is easily blocked, because the volume ratio of catalyst is less, as circular port φ 1.0～1.1mm, irregularly-shaped hole R=0.25～0.35mm is easy at work be stopped up by the impurity in the material, and clears up cumbersome; The 4th, the arrangement mode in moulding hole will influence production efficiency.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiency that prior art exists, and a kind of extruder micro-hole mould is provided, and has the extrusion efficiency height, guarantees to mix to pinch the stable of gap, and the working time is long, the characteristics of long service life.
Extruder micro-hole mould of the present utility model comprises template, several extrusion cavities, and its major technique characteristics are fluted planes on template, and extrusion cavities is arranged on the groove plane.
The groove plane is that formed material mixes and to pinch the gap between extruder and the mould, pinches the gap and is set on the template owing to mix, and can keep mixing and pinch the stable of gap, and prevented that extruder screw from pulling the end face of die hole in rotation.The mixed gap of pinching that depth of groove and material require adapts.Extrusion cavities can be the moulding hole, preferably comprises the tubaeform pilot hole of moulding hole and moulding outer end of hole, and pilot hole is got into material easily.The shape in moulding hole is identical with the catalyst shape of manufacturing.The shape of template and extruder are desired supporting.
Can add boss on the groove plane, general in the center on groove plane, prevent that screw rod from pulling the end face in hole.
The groove plane is general corresponding with the screw rod of extruder, as the relative figure of eight that should be with twin-screw, in the figure of eight two center of arc a boss is arranged respectively.
Template is fluted plane simultaneously, but preferably all there is identical groove plane on its two sides, and the two sides result of use is identical.If extrusion cavities is blocked, mould is unloaded, transfer turnback to reinstall, when driving work again, these impurity that are blocked in the extrusion cavities will be extruded smoothly.Avoided the trouble of cleaning one by one.The micro-deformation that mould produces is at work also eliminated by force direction by change, thereby has improved service life.
Preferably be evenly arranged on the groove plane between extrusion cavities of the present utility model, be convenient to like this arrange, can guarantee that material extrudes smoothly, and can satisfy the requirement of strength of shaped article with the equilateral triangle form.
Advantage of the present utility model:
Mix and to pinch the gap and be arranged on the template, keep mixing and pinches the stable of gap, unlikely play because of extruder screw changes; The rotation of extruder screw can not pulled the extrusion cavities end face, guarantees its service life; Mould can use on the two sides, and by changing the service orientation of mould, eliminates the yielding shortcoming of mould, removes the impurity in the extrusion cavities more easily; The arrangement mode of extrusion cavities has guaranteed extrusion pressure, material can be extruded smoothly, and can satisfy the requirement of strength of shaped article, has improved extrusion efficiency.The utility model is installed on the double screw extruder, mould of every replacing, but continuous operation is more than 40～60 minutes.The average life of every mould is for producing the catalyst prod more than 8～10 tons.The utility model can be produced the little special-shaped catalyst of volume.

Among the figure: 6 pilot holes of 1 template, 2 grooves, 3 extrusion cavities, 4 boss, 5 moulding holes
The specific embodiment
Fig. 1～4 are embodiment of the present utility model.The supporting use of this mould and double screw extruder.Figure of eight groove 2 is arranged on template 1, the two sides is identical, in figure of eight groove two center of arc a boss 4 is arranged respectively, depth of groove is 12 millimeters, whole evenly distributed 1330 extrusion cavities 3 that have in the groove, be evenly arranged in (the part extrusion cavities that only draws among the figure, all the other omissions) on the groove plane with the equilateral triangle form between extrusion cavities.Extrusion cavities 3 is made up of moulding hole 5 and tubaeform pilot hole 6, and the shape in moulding hole 5 is identical with catalyst shape, and Fig. 2, Fig. 3 are respectively the moulding hole of cylinder catalyst, bunge bedstraw herb shape catalyst.The shared area of plane in cylinder moulding hole is 6～7% of groove plane, and the shared area of plane in bunge bedstraw herb formation type hole is 7～8% of groove plane.
Template is by the stainless steel material manufacturing, and thickness is 12 millimeters.
