Seal ring is widely used in production, scientific research and civilian each field, its deficiency is that the chamfering of seal ring is sharp keen horn shape, be beneficial to easy for installation, but in manufacturing process, because the product chamfering is sharp keen horn shape, production mould should be located very sharp, and die sinking is as easy as rolling off a log to scratch product, cause waste product or substandard products, increase cost of production.

The model utility content

The purpose of this utility model is to avoid above-mentioned deficiency of the prior art and a kind of seal ring that the straight vertical raise-position is set of providing, and the sealing circle uses with easy for installation, and low cost of manufacture.

The purpose of this utility model can realize by following measure:

The utility model comprises flanging, circle limit, presses tooth, overhead kick, on the circle limit flanging is set, and is provided with in flanging and presses tooth and straight vertical raise-position, it is characterized in that: on circle inboard, limit the straight vertical raise-position is set, the straight vertical raise-position is set under the flanging inboard.

The mould of manufacturing the said goods comprises male model, master mold, it is characterized in that: on the male model top straight vertical raise-position is set, in the male model lower end straight vertical raise-position is set.

The utility model has following advantage compared to existing technology:

The one, on the utility model circle limit and under the flanging straight vertical raise-position is set, install with easy to use, improve, enhance product performance; The 2nd, this production manufacture process is improved male model, on the male model top and the lower end straight vertical raise-position is set, die sinking is smooth and easy, mould base up-to-standard rate improves, and reduces production costs; The 3rd, adapt to the manufacturing of like product.
