Abstract

The invention discloses a valve oil seal forming machine. The valve oil seal forming machine comprises a forming area and a mold opening area, a forming mold of a valve oil seal comprises an upper mold, a lower mold and a plurality of mold cores, the valve oil seal forming machine is provided with an overturning mechanism, a pre-shaping mechanism and a core ejecting mechanism, and the upper mold is connected with the overturning mechanism; when the forming mold is located in the forming area, the mold cores can be arranged between the upper mold and the lower mold in a clamped mode so that the forming mold can be in a mold closing state, and the pre-shaping mechanism can beat the upper mold; and when the forming mold is located in the mold opening area, the overturning mechanism can drive the upper mold to overturn, and the core ejecting mechanism can eject the mold cores out of the lower mold. According to the valve oil seal forming machine, mold opening and mold closing can be rapidly achieved, and the filling effect of rubber materials can be improved.

Description

technical field [0001] The invention relates to a rubber molding machine, in particular to a valve oil seal molding machine. Background technique [0002] The valve oil seal is one of the important parts of the engine valve group. Its main function is to prevent oil from entering the intake and exhaust pipes, avoid oil loss, prevent the mixture of gasoline and air and exhaust gas from leaking, and prevent engine oil from entering the combustion chamber. Because the valve oil seal is in contact with gasoline and engine oil at high temperatures, it is necessary to use materials with excellent heat resistance and oil resistance, such as fluororubber, nitrile rubber, silicone rubber, polyurethane and polytetrafluoroethylene. [0003] The mold of the valve oil seal in hot pressing is generally composed of an upper mold, a lower mold and multiple mold cores. Each mold core can form a valve oil seal. In order to improve the production rate, the more the number of mold cores, the be...
