Abstract
The utility model discloses a wear -resisting uide bushing, it includes the overcoat body and the inner casing who bonds mutually with this overcoat body, radially is equipped with interior oilhole on this inner casing, and be equipped with on the overcoat body with should in the corresponding outer oilhole of oilhole, be equipped with on this inner casing's the inner wall with the arc slot that interior oilhole is linked together, the utility model has the advantages of reasonable design, including ingenious, the overcoat body goes up the corresponding inside and outside oilhole that is equipped with, lubricating oil can advance between inner casing and the guide pillar through this outer oilhole and interior oilhole fast to fully spread through the arc slot, lubricated effectual, the cooperation is smooth and easy, effectively avoids appearing the dead phenomenon of card, promotes wearability, long service life simultaneously greatly, and inner casing is copper alloy sleeve, and the wearability is better, and furthest increase of service life does benefit to extensive popularization and application.
Description
Technical field
The utility model relates to technical field of mold, is specifically related to a kind of wear-resistant guiding cover being applied on mould.
Background technology
The effect of mould targeting part is extremely important, and the guiding part inside injection moulding, press tool is all very accurate, and the guiding of injection mold is running fit, and monolateral gap is greatly about 0.01; The guiding of press tool is the point cantact roller shrink-fit of guide pillar, guide pin bushing, ball triplicity, it is possible to understand that be negative clearance. Post, cover are contained in different templates respectively, utilize the cooperation of guide pin bushing to ensure the position degree relation of the corresponding part of each template, it is ensured that the precision of product. The guiding of high precision is certain is also a kind of protection for the part in mould, it is possible to its life-span is extended.
In use, owing to guide pin bushing is the body of single structure, its inner hole surface is the smooth surface of mono-disperse, due to comparatively tight with coordinating of cylindrical surface, lubricating oil is difficult to enter between guide pin bushing and guide pillar, causes the adaptation of guide pin bushing and guide pillar smooth and easy not, easily causes orienting sleeve to wear and tear, stuck phenomenon even occurs, it may also be useful to the life-span is short.
Practical novel content
For above-mentioned deficiency, the purpose of this utility model is, it is provided that a kind of smart structural design, rationally, effectively avoid stuck phenomenon occur, and wear resistance is good, it may also be useful to the wear-resistant guiding cover of life-span length.
For achieving the above object, technical scheme provided by the utility model is: a kind of wear-resistant guiding cover, it comprises outer sleeve body and the interior body bonding with this outer sleeve body, on this interior body, radial direction is provided with interior oilhole, and on described outer sleeve body, it is provided with the outer oilhole that oilhole interior with this is corresponding, the arcuate furrow that the inwall of this interior body is provided with described interior oilhole is connected.
Improving as one of the present utility model, described outer sleeve body is high-carbon-chromium bearing steel cover.
Improving as one of the present utility model, described interior body is copper alloy cover.
Improving as one of the present utility model, the inwall two ends of described interior body are provided with down fillet.
The beneficial effects of the utility model are: the utility model reasonable in design, ingenious corresponding on inside and outside body it is provided with inside and outside oilhole, lubricating oil enters between interior body and guide pillar by this outer oilhole and interior oilhole fast, and fully spread by arcuate furrow, high lubricating effect, coordinates smooth and easy, effectively avoids stuck phenomenon occur, greatly promote wear resistance, it may also be useful to the life-span is long simultaneously;And interior body is copper alloy cover, wear resistance is better, extends work-ing life to greatest extent, is beneficial to wide popularization and application.
Below in conjunction with accompanying drawing and embodiment, the utility model is illustrated further.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present utility model.
Fig. 2 is the sectional structure schematic diagram of A-A in Fig. 1.
Embodiment
Embodiment, see Fig. 1 and Fig. 2, a kind of wear-resistant guiding cover that the present embodiment provides, it comprises outer sleeve body 1 and the interior body 2 bonding with this outer sleeve body 1, on this interior body 2, radial direction is provided with interior oilhole 21, and on described outer sleeve body 1, it is provided with the corresponding outer oilhole 11 of oilhole 21 interior with this, the arcuate furrow 22 that the inwall of this interior body 2 is provided with described interior oilhole 21 is connected.
Preferably, described outer sleeve body 1 is preferably high-carbon-chromium bearing steel cover, and hardness height, intensity is good. Described interior body 2 is preferably copper alloy cover, and wear resistance is good. Making copper alloy cover and high-carbon-chromium bearing steel cover bonding by sintering process, structural stability is good, extends work-ing life to greatest extent.
Fillet 23 can be provided with down at the inwall two ends of described interior body 2. The quick and precisely insertion being convenient to guide pillar, brings convenience to dismounting operation.
During use, it is provided with interior oilhole 21 and outer oilhole 11 due to corresponding on interior body 2 and outer sleeve body 1, lubricating oil flows rapidly between interior body 2 and guide pillar by this outer oilhole 11 and interior oilhole 21, and fully spread by arcuate furrow 22, high lubricating effect, coordinates smooth and easy, effectively avoids stuck phenomenon occur, greatly promote wear resistance, it may also be useful to the life-span is long simultaneously.
The announcement of book and instruction according to the above description, above-mentioned enforcement mode can also be changed and revise by the technician of the utility model art. Therefore, the utility model is not limited to embodiment disclosed and described above, modifications and changes more of the present utility model also should be fallen in the protection domain of claim of the present utility model. In addition, although employing some specific terms in this specification sheets, but these terms are just for convenience of description, and the utility model does not form any restriction. As described in the utility model above-described embodiment, other body adopting structure same or similar with it and obtain, all in the utility model protection domain.
