Abstract
The utility model relates to a kind of automobile vacuum pump slide plate, comprises intermetallic composite coating inserts (1), injection structure (2); Described intermetallic composite coating inserts (1) has double-level-metal chip architecture, is connected, and has certain interval in the middle part of described double-level-metal chip architecture; The middle part of described double-level-metal chip architecture has the through hole (1a) flow through for injected plastics material; Described injection structure (2) casting is fixed on the outside of intermetallic composite coating inserts (1), forms integral structure.The utility model well solves vacuum pump slide plate at low temperatures, the situation of unitary plastic strength deficiency; Due to the reduction of injection moulding wall thickness and the uniformity of wall thickness, single injection-molded can reach very high injection moulding precision; Decrease the operation of secondary machine; The usage quantity of material can be reduced, decrease cost; Can more be applicable to common engineering plastics as PPS, nylon, phenolic moulding powder etc., reduce the cost of material; The requirement of more severe operating conditions can be adapted to.
Description
Technical field
The utility model relates to a kind of automobile vacuum pump slide plate, belongs to automobile vacuum pump accessory technical field.
Background technique
Automobile vacuum pump is in the process of work, and vacuum pump often revolves and turns around, and its slide plate just needs to-and-fro motion once, and therefore the intensity of slide plate and anti-fatigue performance seem very important, and existing automobile vacuum pump slide plate generally adopts high-end plastic material.
But the slide plate cost of high-end plastic material is higher, and due to plastics itself, regardless of the material that how high-end employing is, automobile vacuum pump slide plate is in extremely cold environment, or than being easier to the fracture causing vacuum pump slide plate, thus causing automobile to lose the source of vacuum, causing potential safety hazard.
Model utility content
The purpose of this utility model is to provide a kind of automobile vacuum pump slide plate, significantly improves the intensity of slide plate, safety coefficient is obtained and significantly improves; Significantly improve the product size precision of vacuum pump slide plate simultaneously; Avoid secondary machine; Reduce the requirement of plastic materials, thus reduce cost of material.
The utility model takes following technological scheme:
A kind of automobile vacuum pump slide plate, comprises intermetallic composite coating inserts 1, injection structure 2; Described intermetallic composite coating inserts 1 has double-level-metal chip architecture, is connected, and has certain interval in the middle part of described double-level-metal chip architecture; The middle part of described double-level-metal chip architecture has the through hole 1a flow through for injected plastics material; Described injection structure 2 casting is fixed on the outside of intermetallic composite coating inserts 1, forms integral structure.
Further, described automobile vacuum pump slide plate entirety is in rectangular structure.
Further, the middle part of the operative end surface of described automobile vacuum pump slide plate has groove 2a.
A kind of preparation process of above-mentioned automobile vacuum pump slide plate, described metal insert 1 is fixed in injection mould, liquid plastic is entered between the double-level-metal chip architecture of intermetallic composite coating inserts 1 by described through hole 1a, completes intermetallic composite coating inserts 1 and imbeds injection structure 2, forms integral structure.
The beneficial effects of the utility model are:
1) vacuum pump slide plate is well solved at low temperatures, the situation of unitary plastic (PEEK/PPS/PF) strength deficiency;
2) due to the reduction of injection moulding wall thickness and the uniformity of wall thickness, single injection-molded can reach very high injection moulding precision; Decrease the operation of secondary machine;
3) usage quantity of injected plastics material can be reduced, decrease cost;
4) can more be applicable to common engineering plastics as PPS, nylon, phenolic moulding powder etc., reduce material requirements, reduce the cost of material;
5) requirement of more severe operating conditions can be adapted to.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
See Fig. 1-Fig. 4, a kind of automobile vacuum pump slide plate, comprises intermetallic composite coating inserts 1, injection structure 2; Described intermetallic composite coating inserts 1 has double-level-metal chip architecture, is connected, and has certain interval in the middle part of described double-level-metal chip architecture; The middle part of described double-level-metal chip architecture has the through hole 1a flow through for injected plastics material; Described injection structure 2 casting is fixed on the outside of intermetallic composite coating inserts 1, forms integral structure.
See Fig. 3, described automobile vacuum pump slide plate entirety is in rectangular structure.
See Fig. 2, the middle part of the operative end surface of described automobile vacuum pump slide plate has groove 2a.
See Fig. 1-Fig. 4, a kind of preparation process of above-mentioned automobile vacuum pump slide plate, described metal insert 1 is fixed in injection mould, liquid plastic enters between the double-level-metal chip architecture of intermetallic composite coating inserts 1 by described through hole 1a, complete intermetallic composite coating inserts 1 and imbed injection structure 2, form integral structure.
Concrete working process is: adopt powder metallurgy or mach mode to carry out the inserts of construction drawing 1; Then the inserts preheating will made, then puts into injection machine and carries out injection moulding; After being removed by cast gate after injection moulding, the part of the new structure required for us can be obtained.This part has high strength, the feature such as low cost and dimensionally stable; Automobile vacuum pump slide plate can be applied to.
The utility model well solves vacuum pump slide plate at low temperatures, the situation of unitary plastic (PEEK/PPS/PF) strength deficiency; Due to the reduction of injection moulding wall thickness and the uniformity of wall thickness, single injection-molded can reach very high injection moulding precision; Decrease the operation of secondary machine; The usage quantity of material can be reduced, decrease cost; Can more be applicable to common engineering plastics as PPS, nylon, phenolic moulding powder etc., reduce the cost of material; The requirement of more severe operating conditions can be adapted to.
