Description

Technical Field

[0001] The utility model relates to the technical field of air spring production, in particular to a rubber air spring production mould. Background Art

[0002] The rubber air spring is a curved capsule made of rubber and mesh wire, commonly known as air tire, corrugated air tire, air bag, leather tiger, etc. The two ends of the capsule need to be connected with two steel plates to form a compressed air chamber.

[0003] After the rubber air spring is assembled into an assembly, compressed air is filled into the air spring, and the compressibility of air is used to achieve elasticity. It is a non-metallic spring with spring action. At the same time, the rubber air spring has many superior characteristics of metal springs: the rubber air spring has nonlinear characteristics, and its characteristic line can be designed into a relatively ideal curve according to needs; the stiffness of the rubber air spring changes with the load, so that the spring device has ideal characteristics: the rubber air spring can bear axial and radial loads at the same time, and can also transmit torque: the rubber air spring can obtain different bearing capacities by adjusting the internal pressure, so it can adapt to the needs of various loads: the rubber air spring is light in weight and has a long service life: the high-frequency vibration isolation and sound insulation performance of the rubber air spring is good. The rubber air spring requires a small installation space and is easy to replace. Air springs can be divided into three types according to the structural type of the airbag: bladder type, membrane type and composite type. The bladder air spring consists of a rubber airbag with a cord and compressed air enclosed therein. The inner layer of the airbag is made of airtight rubber, and the outer layer is made of oil-resistant rubber. The airbag is generally made into two sections, but there are also single sections or three or four sections. The more sections there are, the better the elasticity is. There are steel waist rings between the sections to prevent the middle part from radial expansion and to prevent friction between the two sections. The upper and lower covers of the airbag seal the airbag.

[0004] The bladder type rubber air spring is usually made by placing the air spring rubber airbag in a production mold, and then steam blowing and vulcanizing it in a vulcanizer. The existing production molds are large in size and weight, inconvenient to operate, and each mold can only be used to produce bladder type rubber air springs with a fixed number of sections, which has poor practicality.
