Description
Technical field
It the utility model is related to a kind of piston, and in particular to a kind of safe die casting piston.
Background technology
The cycle time that powder metallurgy manufactures when parts are manufactured, can carry out large batch of zero in a short time
The manufacture of part, make the manufacturing process of powder metallurgy more good, high intensity, the manufacture of the parts of complicated technology can be met
And assembling, the parts intensity that powder metallurgically manufacturing can be allowed to come out is better, can adapt to the use of different workplaces
Requirement, meet the requirements of different operating modes, but the too many working time that many pistons consume when manufacture,
The top intensity of piston is not fine, have impact on the using effect of piston.
The content of the invention
The purpose of this utility model is to provide that a kind of intensity is good, a kind of safe die casting piston safe to use.
The technical solution of the utility model is：A kind of safe die casting piston, including piston shell, it is provided with described piston shell
Through hole is connected, top plate is provided with the upper end of described piston shell, circular groove is provided with top plate, in described piston shell
Provided with connecting hole, pressing groove is provided with the upper end of connecting hole, high intensity pressing bar is provided with pressing groove.
Described high intensity pressing bar is fine strip shape copper bar, and copper bar is embedded in pressing groove.
Described top plate is integrally formed with piston shell, and connection mesh is provided with described top plate.
Described connection mesh has been embedded in ball, and ball rolls in connection mesh.
The utility model has the advantages that：Top plate is provided with described piston shell, the intensity of piston can be allowed more good,
Avoid at the top of piston shell and occur damaged, have impact on the using effect of piston, pressing bar is provided with piston, can allow piston shell
Intensity it is more good, allow piston more resistant to living extraneous impact.
