Abstract
The utility model discloses a material cavity mould for producing an oil seal by transfer molding press. The material cavity mould comprises a material cavity, a press injection head, injection nozzles, sealing rings and press rings, wherein the bottom of the material cavity is provided with a plurality of funnel-shaped material injection chambers which are concave at the bottom; and the lower end of each material injection chamber is communicated with one injection nozzle. The material cavity mould has the characteristics that rubber can easily flow in the material cavity by the combination of the production technology of the rubber, the structure is simple, and the oil seal can be produced by transfer molding press.
Description
Technical field
The utility model belongs to oil-tight mould production equipment technical field, is related to the material cavity mould that a kind of transfer molding mode produces oil sealing.
Background technology
The material cavity mould bottom shape that current transfer molding mode produces oil sealing is plane, and material bottom of chamber portion, which is provided with injection nozzle, production process, expects that chamber is added after rubber, and rubber poor fluidity at material bottom of chamber facial planes, production technology is bad.
The content of the invention
The purpose of this utility model is to improve the deficiency of prior art and provide a kind of production technology of bound rubber, rubber is easier the material cavity mould that flowing, transfer molding mode simple in construction produce oil sealing in material chamber.
What the purpose of this utility model was realized in, a kind of transfer molding mode produces the material cavity mould of oil sealing, including material chamber, pressure injection head, injection nozzle, sealing ring, trim ring composition, its feature is the funnel-form material feeding room for expecting bottom of chamber portion provided with multiple depressions in bottom, and the lower end of material feeding room is communicated with injection nozzle.
Compared with the prior art the utility model has following distinguishing feature and good effect：The utility model is the funnel-form material feeding room for expecting bottom of chamber portion provided with multiple depressions in bottom, the lower end of material feeding room is communicated with injection nozzle, material bottom of chamber portion is filled with flat shape at nozzle upper end and is processed into funnel shaped or chamfering circular arc shape, rubber is easier flowing at material bottom of chamber portion, and device Host pressure can be reduced, while can be reduced investment outlay using existing equipment transformation, and it is simple in construction, beneficial to implementation.
