Problems solved by technology

[0004] At present, the process of making plastic-rubber composite parts is similar to that of traditional metal-rubber parts, but for automotive structural parts, this process has the following defects: According to the traditional process, the plastic bracket and the rubber main spring generally need to be vulcanized simultaneously However, due to the larger bracket and the more complex plastic structural parts compared to the metal structure, the cost of the rubber mold is higher, the edge sealing and pressure retention are more difficult, and the manufacturing process is also more difficult, especially when the plastic bracket and rubber are exposed to high temperature. Vulcanized together in the mold, during the long-term vulcanization process of 5-20 minutes, it is easy to cause degradation or shape change of the plastic, thereby reducing the performance and service life of engineering plastics

Embodiment 1

[0033] A method for manufacturing a lightweight rubber shock absorber for automobiles, wherein the rubber shock absorber is composed of a rubber main spring, a plastic bracket and a metal insert, and the manufacturing method includes the following steps:

[0034] (1) Vulcanization: Put the rubber main spring 2 into a vulcanization mold for vulcanization treatment, apply a vulcanization pressure of 10 MPa to the vulcanization mold, control the vulcanization treatment temperature to 140°C, and set the vulcanization treatment time to 20 minutes.

[0035] In this step, the material of the main rubber spring is selected from natural rubber, butadiene rubber, styrene-butadiene rubber or a mixture of several in any proportion.

[0036]In this step, the mixed rubber material used in the rubber main spring 2 is prepared by using the traditional mixing process, and the components of the mixed rubber are weighed: 100g natural rubber SVR3L, 5g zinc oxide ZnO, 1.5g stearic acid, 1g micro C...

Embodiment 2

[0046] Embodiment 2: Other parts are the same as Embodiment 1, the difference is that a vulcanization pressure of 20 MPa is applied to the vulcanization mold during vulcanization in step (1).

Embodiment 3

[0047] Embodiment 3: Other parts are the same as Embodiment 1, the difference is that a vulcanization pressure of 30 MPa is applied to the vulcanization mold during vulcanization in step (1).
