In order to achieve the purpose, the utility model adopts the technical scheme that: the utility model provides a plastics shaping car leaf spring cushion of metal reinforcing, includes rectangular plastic body, the top surface of plastic body and bottom surface centre all are equipped with spacing blind hole. A plurality of metal reinforcing cylinders vertically penetrate through the plastic body, the metal reinforcing cylinders are uniformly distributed around the limiting blind holes, and the top surface and the bottom surface of each metal reinforcing cylinder are flush with the top surface and the bottom surface of the plastic body respectively.

Furthermore, the limiting blind holes are round holes.

Furthermore, the bottom edge of the round hole is processed by round chamfering.

Further, the vertical edge of the plastic body is processed by a round chamfer.

Further, the top surface of the plastic body is an inclined surface.

Preferably, the number of the metal reinforcing cylinders is 4.

Preferably, the metal reinforcing cylinder is made of steel.

Preferably, the depth of the limiting blind hole is 12-16 mm.

Preferably, the plastic body is made of nylon.

Preferably, the inclination angle of the inclined plane is 3-5 degrees.

Compared with the prior art, the utility model has the following beneficial effects:

according to the utility model, the steel cylinder is inserted in the nylon plate spring cushion block, so that the weight can be greatly reduced on the premise of ensuring the strength, the weight of the whole automobile is further reduced, and the oil consumption of the automobile is reduced.

In the utility model, the steel cylinder is inserted in the nylon plate spring cushion block, so that the service life of the plate spring cushion block is greatly prolonged, and the plate spring cushion block can be used for a long time.

In the utility model, the main material of the plate spring cushion block is nylon, and the nylon is cheap and easily available plastic material, so that the raw material cost is greatly reduced compared with metal material.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.

As shown in fig. 1-3, a metal-reinforced plastic molded automobile leaf spring cushion block comprises a rectangular nylon plastic body 1, wherein a vertical edge 101 of the plastic body 1 is processed by a round chamfer, the top surface of the plastic body 1 is an inclined surface 102, and the inclination angle of the inclined surface is 4 degrees. The top surface and the bottom surface of the plastic body 1 are both provided with a 14mm deep limiting blind hole 2 at the center, the limiting blind hole 2 is a round hole, and the edge of the bottom surface of the round hole is processed by a round chamfer. 4 steel metal reinforcing cylinders 3 vertically penetrate through the plastic body 1, the metal reinforcing cylinders 3 are uniformly distributed around the limiting blind holes 2, and the top surface and the bottom surface of each metal reinforcing cylinder 3 are flush with the top surface and the bottom surface of the plastic body 1 respectively.

It should be noted that the working principle of the metal reinforced plastic formed automobile plate spring cushion block of the utility model is as follows: the forming process can be poured by adopting nylon during the forming of the plastic body 1 of the plate spring cushion block, the metal reinforcing cylinder 3 made of steel is embedded in the die when the plastic body 1 is formed, and is integrated with the plastic body 1 after mould pressing or injection molding, the metal reinforcing cylinder and the plastic body are tightly combined to prevent the long-term stress creep of the nylon and prolong the service life of the plate spring cushion block.
