Abstract
The invention belongs to the field of plastic machine parts and particularly relates to an oil seal mechanism for a plastic machine. The oil seal mechanism comprises a copper sleeve, a plurality of annular T-shaped grooves are formed in the circumferential face of the sleeve, T-shaped sealing rings are embedded in the T-shaped grooves, an installation step is arranged in the sleeve and fixedly provided with an inner sealing ring, an annular rectangular groove is formed in the end face of the inner sealing ring, a plurality of elastic components are fixedly arranged in the rectangular groove in the radial direction, and the notch of the rectangular groove is sealed with a sealing gasket. The oil seal mechanism has the advantages of being simple and practical in structure and capable of playing a role in interior and exterior reliable sealing through the T-shaped sealing rings and convex ridges of the inner sealing ring.
Description
Technical field
The invention belongs to plastics machinery accessory field, specifically a kind of oil seal mechanism for plastics machinery.
Background technique
Oil sealing is mainly used in sealing low pressure working medium or lubricant oil leaks and prevents extraneous dust, impurity invasion device interior, at all kinds of oil hydraulic pump, the running shaft of oil hydraulic motor widely uses oil sealing, leak to stop the leakage oil in active chamber, now for the standard seal part of running shaft, usual employing be packing_seal, rubber seal, labyrinth seal, although but packing_seal economical but seal unreliable, often there will be the situation of leakage, and rubber seal Applicable temperature and pressure range limitation, the situation that then ageing of rubber comes off easily is produced when external environmental factor changes, sealing effect is poor, labyrinth seal belongs to clearance seal, manufacture difficulty of processing is large, therefore in field of plastic machinery, also there is no good oil seal structure.
Summary of the invention
The present invention is directed to the deficiency existed in above-mentioned technology, propose the oil seal mechanism for plastics machinery of a kind of good sealing effect, long service life.
The invention provides following technological scheme:
For the oil seal mechanism of plastics machinery, it comprises copper sleeve, this sleeve side face is provided with the T-shaped groove of some annulars, T-shaped groove is embedded in T-shaped seal ring, be provided with an installation step in sleeve, installation step is fixed with inner seal ring, the end face of inner seal ring is provided with the rectangle groove of annular, in rectangle groove, radial direction is fixed with some elastic members, and the notch of rectangle groove is sealed by sealing gasket.
Described T-shaped seal ring protrudes from sleeve outer surface.
The inwall of described inner seal ring is provided with corrugated convex ridge.
Advantage of the present invention is simple and practical, reliably seal action inside and outside playing by the convex ridge of T-shaped seal ring and inner seal ring.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, it comprises copper sleeve 1, this sleeve 1 side face is provided with the T-shaped groove of some annulars, T-shaped groove is embedded in T-shaped seal ring 2, be provided with an installation step in sleeve 1, installation step be fixed with inner seal ring 3, the end face of inner seal ring 3 is provided with the rectangle groove of annular, in rectangle groove, radial direction is fixed with some elastic members 4, and the notch of rectangle groove is sealed by sealing gasket 5.
Described T-shaped seal ring 2 protrudes from sleeve 1 outer surface.
The inwall of described inner seal ring 3 is provided with corrugated convex ridge 3a.
