[specific embodiment]
The utility model discloses a kind of high life extruder, including the back rest, front-axle beam and it is mounted on the front-axle beam and the back rest
Between dynamic beam, the front-axle beam is slidably fitted with extrusion die towards the side for moving beam, and the extrusion die includes metal die body
Be mounted on the intracorporal ceramic die body of metal mold, the end face of the metal die body protrudes from the ceramics towards the dynamic beam direction
Die body, the height that the end face of the metal die body protrudes from ceramic die body end face is 0.9mm~1.2mm.
In this way, which the end face of metal die body can be consistently higher than ceramics during extrusion die is in high temperature extrusion
The end face of die body causes metal mold body that can form a protective to ceramic die body, ceramic die body is avoided laterally to be pressed
Power, it is non-breakable after protecting ceramic die body to squeeze for a long time, to extend the service life of extruder；In addition, this is practical
The novel height for also protruding from ceramic die body end face to the end face of metal die body is defined, protrusion height be 0.9mm~
1.2mm, so, be not only avoided that cause because protrusion height is smaller metal die body can not effective protection ceramics die body, but also can keep away
It is easily-deformable to exempt from the part for causing metal die body to be higher by because protrusion height is excessive, deformed metal stream is caused to embrace ceramic die orifice,
Or impurity is flowed into blank.
The technical solution of the utility model embodiment is explained below with reference to the attached drawing of the utility model embodiment and
Illustrate, but following embodiments are only the preferred embodiment of the utility model, and not all.Based on the implementation in embodiment
It is practical newly to belong to this for example, those skilled in the art's obtained other embodiments without making creative work
The protection scope of type.
As shown in Figures 1 to 3, the extruder in this preferred embodiment includes the back rest, dynamic beam and front-axle beam 1, before dynamic beam is mounted on
Between beam 1 and the back rest, the side of front-axle beam 1 towards dynamic beam is slidably fitted with extrusion die 2, and extrusion die 2 includes metal die body 21
Ceramic die body 22 is protruded from towards dynamic beam direction with the end face of the ceramic die body 22 being mounted in metal die body 21, metal die body.
In this way, which the end face of metal die body can be consistently higher than ceramics during extrusion die is in high temperature extrusion
The end face of die body causes metal die body 21 that can form a protective to ceramic die body 22, avoid ceramic die body 22 by
Lateral pressure, it is non-breakable after protecting ceramic die body 22 to squeeze for a long time, to extend the service life of extruder；Separately
Outside, the height that the utility model also protrudes from ceramic die body end face to the end face of metal die body is defined, and protrusion height H is
0.9mm~1.2mm, when protrusion height H is less than 0.9mm, protrusion height is smaller to cause metal die body 21 can not effective protection pottery
Ceramic former body 22；When protrusion height H is greater than 1.2mm, protrusion height is excessive, and the part for causing metal die body 21 to be higher by is easily-deformable,
Cause deformed metal stream to embrace ceramic die orifice, or impurity is flowed into blank.For this purpose, the protrusion height in the present embodiment
H is 0.9mm~1.2mm, and so, be both avoided that causes metal die body 21 can not effective protection ceramics because protrusion height is smaller
Die body 22, and it is avoided that the part for causing metal die body 21 to be higher by because protrusion height is excessive is easily-deformable, cause deformed metal
Stream embraces ceramic die orifice, or impurity is flowed into blank.The preferred 1mm of protrusion height H in the present embodiment, certainly, optionally
Be, protrusion height H can also be 0.9mm, 1.1mm and 1.2mm, as long as protrusion height H between 0.9mm and 1.2mm, this
In will not enumerate, it is above-mentioned it is listed be only preferred embodiment, be not used to limit this range.
In order to increase the mobility of metal, the end face of metal die body is radially-inwardly to incline from high to low in the present embodiment
Oblique inclined-plane 211.The inclination angle alpha on inclined-plane 211 is 3 °~5 °.When inclination angle alpha is less than 3 °, the difficulty of processing on inclined-plane 211
Larger, the mobility of metal is weaker；When inclination angle alpha is greater than 5 °, the stress surface for easily leading to metal die body 21 is smaller, so as to cause
Metal die body 21 is broken.For this purpose, inclination angle alpha is 3 °~5 ° in the present embodiment, in this way, which adding for inclined-plane 211 can be reduced
Work difficulty, and it is avoided that the stress surface for leading to metal die body 21 because tilt angle is excessive is reduced, it is broken so as to cause metal die body 21
It is broken.Preferably 4 ° of inclination angle alpha in the present embodiment, certainly, optionally, inclination angle alpha can also be 3 °, 3.5 °, 4.5 ° and 5 °,
As long as inclination angle alpha will not enumerate here between 3 ° and 5 °, it is above-mentioned it is listed be only preferred embodiment and
, not it is used to limit this range.
In order to simplify the assembling of ceramic die body 22 and metal die body 21, metal die body 21 is equipped with installation in the present embodiment
Slot, ceramic die body 22 are interference fitted with mounting groove, and the inner face of ceramic die body 22 is resisted against on the bottom wall of mounting groove.So set
Meter eliminates both fixed components.
In addition, being additionally provided with mould bases slide plate 3 in the present embodiment on front-axle beam 1, extrusion die 2 is slidably mounted on mould bases slide plate 3,
And it is moved back and forth along the left and right directions of mould bases slide plate 3.Preferably, extrusion die 2 is equipped with backing plate, pad close to the side of front-axle beam 1
Plate is fixed with extrusion die 2 by screw, and backing plate can be moved back and forth along the left and right directions of mould bases slide plate 3.
As shown in Figs. 4-6, mould bases slide plate 3 includes seperated molding upper slide 31, middle slide plate 32 and lower skateboard 33, upper cunning
Plate 31, middle slide plate 32 and lower skateboard 33 are mounted on front-axle beam 1 by screw respectively.It is designed in this way, each slide plate can be reduced
Processing dimension reduces machining deformation, simultaneously because in actual use, the abrasion of upper slide 31 and lower skateboard 33 is more serious,
Middle slide plate 32 will not be worn substantially, therefore only need to change upper slide 31 and lower skateboard 33, reduce the cost of spare unit.
In order to reduce the screw fixed quantity on upper slide 31 and lower skateboard 33, the bottom of upper slide has in the present embodiment
Upper positioning step 311, the top of lower skateboard are equipped with lower positioning step, and the top of middle slide plate is fixed equipped with upwardly extending and being fitted in
The upper extension board 321 of position step 311, the surface of upper extension board 321 and the flush of upper slide 31, the bottom of middle slide plate is equipped with
The lower extension board 322 of lower positioning step is extended downwardly and is fitted in, the surface of lower extension board 322 and the surface of lower skateboard 33 are flat
Together.In this way, which the bottom edge of upper slide and the top margin of lower skateboard can be fitted on front-axle beam 1 by middle slide plate 32, reduced with this
Screw fixed quantity on upper slide 31 and lower skateboard 33.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, being familiar with the those skilled in the art should be understood that the utility model includes but is not limited to attached drawing and specific embodiment party above
