Abstract
The utility model discloses a high-temperature sealing copper ring of a plastic extruder, which comprises an annular body, and two acting surfaces which are perpendicular to the axis of the annular body and arranged between the outer diameter and the inner diameter of the annular body are arranged in parallel. Therefore, the sealing copper ring increases the contact face between the copper ring and pipe openings of pipe fittings, thereby greatly increasing sealing effects. The copper ring and the pipe fittings are heated to expand, so that combination of the copper ring and the pipe fittings are tighter, sealing effects are better, service life is long, replacement frequency of the sealing copper ring is reduced, and production efficiency is increased.
Description
Technical field
The utility model belongs to the plastic extruder technical field of sealing technology, is a kind of elevated-temperature seal copper ring that is applied on the plastic extruder specifically.
Background technique
Need heat plastic pellet during plastic extruder work; Make it to be in molten state; And extrude through twin-screw or single screw rod and to drench multiple or extrude moulding through moulding mould; Plastic pellet gets into extruder until extruding, and needs through preheating and the heat tracing in screw rod extruding, extrusion process, and the melt temperature of particle is generally more than 200 ℃; So temperature all remains on 200～300 ℃ in the extruder plastic pellet Screw Extrusion, keep the molten state of plastic pellet to be convenient to mobile extruding.
Because the extruding of screw rod; Melted material is in the effect current downflow of pressure; The barrel of extruder melted material process prevents melted material at joint leadkage in the joint with the seal ring sealing, and the extruder seal ring adopts exotic materials such as silica gel, asbestos to process more at present.But it is aging that silica gel and asbestos system seal ring at high temperature are prone to, and crackle occurs, and seal failure causes material to leak, and life cycle is short, reach good sealing effect, and necessary frequent replacing seal ring has caused frequent shutdown like this, has had a strong impact on manufacturing efficiency.
Summary of the invention
To the deficiency that existing technology exists, the utility model technical problem to be solved is, a kind of simple in structure, with low cost, plastic extruder elevated-temperature seal copper ring of improving sealing effect and manufacturing efficiency is provided.
For solving the problems of the technologies described above; The technological scheme that the utility model is taked is: a kind of plastic extruder elevated-temperature seal copper ring; Comprise a ring body, the face that two between said ring body external diameter and the internal diameter is set to be parallel to each other perpendicular to the acting surface of said ring body axis.
The advantage of the utility model plastic extruder elevated-temperature seal copper ring is: this copper ring is provided with two parallel acting surfaces, has increased the surface of contact of itself and the pipe fitting mouth of pipe, has improved sealing effect greatly; Copper ring and pipe fitting expanded by heating; In conjunction with tightr, sealing effect is better, long service life; Reduce seal ring and changed frequency, improved manufacturing efficiency.
Description of drawings
Fig. 1 is the perspective view of the utility model;
Fig. 2 is the user mode figure of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is explained further details;
As shown in Figure 1, a kind of plastic extruder elevated-temperature seal copper ring comprises a ring body 1, the face that two between the external diameter of ring body 1 and the internal diameter is set to be parallel to each other perpendicular to the acting surface 11 of said ring body axis.
As shown in Figure 2, present technique is used the copper wire rod of the about 2.5mm of diameter, and wire rod is welded into ring; The diameter of ring is between the external diameter and internal diameter of pipe fitting interface; When extruder pipeline 2 is installed, copper ring is placed on the interface 3 of extruder pipeline 2, copper ring is in the position between the inside and outside caliber of interface 3; It is fastening to pressurize, and the interface 3 of extruder pipeline 2 is combined with copper ring closely.
Certainly, above-mentioned explanation is not to be the restriction to the utility model, and the utility model also is not limited to above-mentioned giving an example; Those skilled in the art; In the essential scope of the utility model, the variation of making, remodeling, interpolation or replacement all should belong to the protection domain of the utility model.
