Abstract
The utility model relates to a kind of exhaust apparatus suitable for extruder；Including squeezing cylinder, squeezing out piston and squeezing out grinding tool；It further include the extrusion board being arranged in below piston, the extrusion board includes extrusion board one and extrusion board two；The extrusion board is the cylindrical body being equipped with；The extrusion board one is in close contact with extrusion board two.Easily the intracorporal air of extruder chamber is discharged for the utility model exhaust apparatus, improves extrusion efficiency, reduces production cost.
Description
Technical field
The utility model relates to ceramic rod technical field more particularly to a kind of exhaust apparatus suitable for extruder.
Background technique
Zirconia ceramics stick-plunger application field: extra-fine grinding equipment, fine chemistry industry, electric slurry, semiconductor, new energy
Source, nanometer new material, medical instrument, hot investment casting, structural ceramics, refractory material, telecommunications, sensitive ceramic, petrochemical industry,
Aerospace, machine-building, optical fiber connector, each high-precision end field such as battery material.Ceramic rod in process of production, needs
The ceramic rod to be fired that prepared porcelain to be extruded is passed through into extrusion machine equipment extrusion molding.Existing extrusion machine equipment
When squeezing out, since the intracorporal air of chamber in extruder is not easy to be discharged, cause the extrusion efficiency in the ceramic rod of extrusion low,
It is also easy to produce rejected product.
Utility model content
In view of the drawbacks of the prior art, it the utility model proposes a kind of exhaust apparatus suitable for extruder, will easily squeeze
The intracorporal air discharge of machine cavity out, improves extrusion efficiency, reduces production cost.
To achieve the above object, the utility model proposes a kind of exhaust apparatus suitable for extruder；Including squeeze cylinder,
It squeezes out piston and squeezes out grinding tool；It further include the extrusion board being arranged in below piston, the extrusion board includes extrusion board one and squeezes out
Plate two；The extrusion board is the cylindrical body being equipped with；The extrusion board one is in close contact with extrusion board two.
The diameter of the extrusion board one is greater than the diameter of extrusion board two, and the diameter of the extrusion board two, which is less than, squeezes cylinder
Internal diameter.
The extrusion board one and extrusion board two are cylindrical body, and the thickness of extrusion board two is greater than the thickness of extrusion board one.
The extrusion board one is rigid plastic sheet, and extrusion board two is rubber slab.
Beneficial effect
The utility model is put by the extrusion board two of the rubber material of setting and the extrusion board one of duroplasts material in porcelain
After setting in extrusion cylinder body, extrusion board setting is being squeezed out into piston in the following, by squeezing out piston and extrusion board for porcelain by squeezing
Grinding tool squeezes out the porcelain rod needed out.Since the extrusion board two of rubber material itself has certain coefficient of expansion, live when squeezing out
When stopper rod squeezes porcelain by extrusion board, extrusion board one and extruding cylinder that the intracorporal air of extrusion cylinder passes through rubber material
Between gap discharge, extrusion board one is that duroplasts material is arranged and squeezes out between piston and rubber extruding plate two in metal, makes to squeeze
The diameter of ejecting plate one is greater than the diameter of extrusion board two, and air of being more convenient for is from rubber slab and squeezes the gap discharge between cylinder.It mentions
High extrusion efficiency reduces substandard product rate.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
The utility model proposes a kind of exhaust apparatus suitable for extruder；Including squeezing cylinder 1, squeezing out 2 and of piston rod
Squeeze out grinding tool 3；It further include the extrusion board 4 being arranged in below piston, the extrusion board 4 includes extrusion board 1 and extrusion board two
42；The extrusion board 4 is the cylindrical body being equipped with；The extrusion board 1 is in close contact with extrusion board 2 42.
The diameter of the extrusion board 1 is greater than the diameter of extrusion board 2 42, and the diameter of the extrusion board 2 42, which is less than, to be squeezed
The internal diameter of cylinder 1.
The extrusion board 1 and extrusion board 2 42 are cylindrical body, and the thickness of extrusion board 2 42 is greater than extrusion board 1
Thickness.
The extrusion board 1 is rigid plastic sheet, and extrusion board 2 42 is rubber slab.
The utility model makes the straight of the extrusion board 2 42 of rubber material by the extrusion board 1 and extrusion board 2 42 of setting
Diameter is greater than the diameter of the extrusion board 1 of duroplasts material, and the thickness of extrusion board 2 42 is greater than the thickness of extrusion board 1.It squeezes out
The diameter of plate 1 is mutually matched with the internal diameter for squeezing cylinder 1, meanwhile, the diameter of extrusion board 2 42 is less than the straight of extrusion board 1
Diameter.Since when squeezing out, extrusion board 2 42 can be deformed gradually under the effect of the pressure, the outer wall of last extrusion board 2 42 and extruding
The inner wall of cylinder 1 is fitted close, and when starting to squeeze, and the gas for squeezing cylinder 1 can be made upwardly through extrusion board and to squeeze
Gap discharge between pressure cylinder body, when avoiding the air in extrusion chamber 11 that from can not being discharged, causes the porcelain item squeezed out to interrupt, generates
Substandard product.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
