Description
Technical field
The utility model relates to the injection structure of air throttle of car cover plate, particularly relates to an injection moulding PIN needle assembly in a kind of air throttle of car cover plate.
Background technique
Closure is used to control one controllable valve that air enters car engine, be a requisite assembly, and closure cover plate is the parts that closure must be installed.Closure cover plate is primarily of compositions such as cover plate, PIN needle assemblies.Current closure cover plate is when the injection moulding of product assembly, and liquid and air along an injection moulding PIN needle module permeate, can arrive the internal surface of assembly, cause the assembly inner inlet of cover plate and lost efficacy; And when doing air tightness test correlation test, tightness cannot reach requirement.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of injection moulding PIN needle assembly improved in the tightness of cover plate and the air throttle of car cover plate of water proofing property.
The utility model solves the problems of the technologies described above adopted technological scheme: an injection moulding PIN needle assembly in a kind of air throttle of car cover plate, comprise motor PIN group, conjuncted PIN group and an injection molding body, the plug end PIN needle of described motor PIN group and the plug end PIN needle of described conjuncted PIN group and described injection molding body perpendicular and be injection molded into and be integrated, described motor PIN group and described conjuncted PIN group are positioned at the both sides of a described injection molding body, the first tapered strip that the upper surface integrated injection molding of a described injection molding body has at least one circle to raise up, the first described tapered strip is centered around outside the plug end PIN needle of described motor PIN group and the plug end PIN needle of described conjuncted PIN group, the middle part of a described injection molding body is provided with the spacing block raised up, all plug end PIN needle are respectively in the both sides of described spacing block, the second tapered strip is provided with between two adjacent plug end PIN needle, the second described tapered strip integrated injection molding in described injection molding body upper surface and integrally extend to the side of described block, the cross section of the first described tapered strip and the second described tapered strip is triangle, the plug end PIN needle of described motor PIN group and the plug end PIN needle of described conjuncted PIN group are provided with the first groove of at least one level.
The lower end integrated injection molding of the outer side surface of a described injection molding body has triconic article, and the cross section of described triconic article is triangle.
The first described tapered strip is at least two circles, when quadric injection mould stream is through this place, can, by whole for the tip of the first tapered strip melting, the first tapered strip and secondary injection plastics be combined completely.
The horizontal component of described motor PIN group is provided with the second groove.
The motor side PIN needle of described motor PIN group is provided with the 3rd groove of at least one level.
The horizontal component of described motor PIN group and the horizontal component of described conjuncted PIN group are provided with positioning hole, and motor PIN group and conjuncted PIN group can accurately be located when injection molding.
Compared with prior art, the utility model has the advantages that due to an injection molding body being provided with the first tapered strip and the second tapered strip, closure cover plate adds man-hour at quadric injection mould, secondary injection plastics are through the first tapered strip and the second tapered strip, injection molding composition produces shearing force at this place, the temperature of injection molding composition at this place is raised, and one time injection molding body is more easily melted, and is well combined with secondary injection plastics; Again owing to the plug end PIN needle of motor PIN group and the plug end PIN needle of conjuncted PIN group being provided with the first groove of at least one level, when secondary injection plastics flow along PIN needle, effectively can increase the length surface of PIN needle, and secondary injection plastics can produce shearing force at groove, secondary injection plastics and PIN needle are raised in the temperature of groove, make the welding of secondary injection plastics and PIN needle better, improve the tightness of closure cover plate after quadric injection mould and water proofing property, ensure that the reliable operation of vehicle air throttle; In addition, because the head of the first tapered strip and the second tapered strip is sharp, when this place crossed by quadric injection mould stream, the material due to head is thick very little, is easy to be melted.
