Description
Technical Field
The application relates to the field of metal connectors and fasteners, in particular to an insert for a plastic part of an automobile engine.
Background
The safety of the engine and the stability of the operation of the engine are ensured by the components around the automobile engine, the stability and durability to the maximum degree can be ensured by adopting the traditional metal components and connecting pieces, but the weight is overlarge, so that unnecessary additional oil consumption is added to the automobile. For the light design, more and more automobile non-core parts adopt plastic parts, such as front and rear connecting plates, a housing and the like of an engine, which can often meet the strength requirement under mild conditions, but the high temperature generated by the engine also easily causes the plastic parts to be more easily aged, creeped and damaged.
At present, the improvement method is to add reinforcing ribs or embed some parts by metal inserts, but the stress concentration is often caused, or the plastic part is heated unevenly. The regular shape of the existing inserts also easily ensures that the binding fastness and uniformity of the inserts and plastic parts cannot be ensured, and further causes the problem of uneven mechanics and heat.
The application provides an insert for a plastic part of an automobile engine, which aims to improve the technology, achieve better sealing performance and stress heating uniformity and improve comprehensive use performance.
Disclosure of Invention
The application aims to: in order to strengthen the stability of fixing the periphery of an automobile engine on the basis of light weight, the application develops an insert for an automobile engine plastic part so as to solve the problems in the prior art.
The application comprises the following steps: the insert for the plastic part of the automobile engine is made of metal, is injection molded in the plastic part, and comprises an insert base column which is integrally hollow cylindrical, and a first annular bottom plate and a second annular bottom plate which are connected to the periphery of the insert base column, wherein threads are formed in the insert base column, protruding points are circumferentially arranged on the outer surface of the insert base column, one of the first bottom plate and one of the lower bottom plate of the insert base column are respectively distributed, the outer end surfaces of the two first bottom plates are respectively flush with the upper bottom surface and the lower bottom surface of the insert base column, and the second bottom plate is identical to the first bottom plate in shape and size and is respectively distributed inwards along the first bottom plate; and curved grooves are uniformly formed in the first bottom plate and the second bottom plate in the circumferential direction.
Preferably, the distance between the pair of first bottom plates and the pair of second bottom plates on the upper side or the lower side of the insert base column is the same. The distances between the first bottom plate and the second bottom plate are equal, so that the stress and the structural mechanics of the upper side and the lower side of the embedded insert base column are balanced.
Preferably, the curved groove is circular arc-shaped, and the bending direction is along the circumferential direction of the edge of the first bottom plate or the second bottom plate. The arc shape and the bending direction of the curved groove lead the stress caused by the rotation and dislocation of the insert to be difficult to damage the insert and the plastic piece.
Further, the curved grooves are identical in shape and size, and the positions of the curved grooves on the first bottom plate and the second bottom plate are identical in distribution. The shape, the size and the distribution of the curved grooves enable the curved grooves to obtain a better stress pattern after injection molding and embedding, so that the overall stability is good.
Preferably, the protruding points are distributed in a spiral shape on the outer surface circumference of the insert base column. The bumps and their helical distribution enable them to increase the coefficient of friction and resistance to rotational stress after embedding.
Preferably, a plurality of connecting columns are uniformly connected between the pair of second bottom plates in the circumferential direction. The arrangement of the connecting column is more beneficial to the embedding bonding fastness, the sealing performance and the stress heating uniformity of injection molding.
Further, the number of the connecting columns is 3-6. The number of the connecting columns achieves the uniformity of economy and performance.
Compared with the prior art, the application has the beneficial effects that: the insert for the plastic part of the automobile engine has the advantages of exquisite structure and good comprehensive performance. The shape of the whole insert is very suitable for embedding the housing type component; the screw thread inside the insert base column can be connected with an external screw nut; the first bottom plate and the second bottom plate improve the distribution of structural mechanics, stress caused by the rotation direction dislocation of the curved slot inserts on the first bottom plate and the second bottom plate is controlled in a directed manner, and embedding is enhanced; the convex points and the spiral distribution increase friction coefficient and anti-rotation capability; the connection column further enhances the tightness and the stress heating uniformity. The insert is used for plastic parts such as a housing, a baffle and a connecting plate of an automobile engine, is simple to embed, has high combination fastness and sealing performance, is good in stress heating uniformity, has high practical value and has wide application prospect.
