Description

Sealing ring die

Technical Field

The utility model relates to a cotton processing technology field of bubble especially relates to a sealing washer mould.

Background

As is well known, some mechanical equipment need to prevent the internal lubricating medium from leaking outwards, and simultaneously need to prevent impurities such as external dust from entering the equipment, therefore, a rubber sealing ring with a special-shaped framework (as shown in figure 1) is needed, the sealing ring contains a framework, 8 through holes are uniformly arranged along the circumferential direction of the sealing ring, 2 trapezoidal bosses are arranged on the inner periphery of the framework, a metal framework is used for enhancing the rigidity of the rubber sealing ring and is beneficial to assembly or mechanical connection, and nitrile rubber is selected as a sizing material because the oil resistance, heat resistance, compression permanent deformation and wear resistance of vulcanized rubber are required to be higher. The forming mode of the rubber product comprises a mould pressing method, a mould moving method, an injection molding method and the like, and at present, the production efficiency of the mould moving method and the injection molding method is low, and the process is relatively complex, so that a mould pressing vulcanization mould which has high production efficiency and can form the rubber product with a complex structure at one time is designed.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that will solve is: the sealing ring die is high in production efficiency and good in product quality.

In order to solve the technical problem, the utility model discloses a technical scheme is: a seal ring mold, comprising: the lower end of the upper die is provided with the middle die, the lower end of the middle die is provided with the lower die, the lower die is provided with the core die, a core locating pin is arranged between the core die and the lower die, a cavity is formed between the upper die, the middle die, the lower die and the core die, a metal framework is arranged in the cavity, a metal framework cylindrical pin is connected between the lower end of the metal framework and the lower die, the lower end of the upper die is connected with a forming cylindrical pin, the upper die and the lower die are respectively provided with a first residual glue groove close to the cavity side, the upper end and the lower end of the core die close to the cavity side are respectively provided with a second residual glue groove, and the lower die on the lower.

Preferably, the middle side of the upper die is connected with a die opening.

Preferably, the middle die is provided with a rounded corner R1 close to the short side of the die cavity.

The utility model relates to a sealing washer mould's advantage is: simple structure, the location is firm, and the drawing of patterns is convenient, has guaranteed the outward appearance effect of sealing washer, and production efficiency is high, and product quality is good, plays good sealed effect.
