Abstract
The invention discloses a piston air cylinder for pressure casting. The piston air cylinder comprises a piston, a piston rod and an air cylinder. The piston rod is arranged at the back end of the piston. The piston and the piston rod are arranged in the air cylinder. A material injection opening is formed in the upper end of the back side of the air cylinder. The piston air cylinder for pressure casting has the advantages of being high in reliability, good in air tightness, long in service life and good in heat preservation performance, part replacing is convenient, price is low, and meanwhile the piston air cylinder has wide market prospect in the pressure casting industry.
Description
Technical field
The present invention relates to die cast field, particularly relate to a kind of die casting piston-cylinder.
Background technology
The essence of compression casting is under High Pressure, make liquid state or semi liquid state metal with higher speed filling die-casting die die cavity, and at forming under the pressure with solidify and obtain the method for foundry goods, because the piston of compression casting need to directly push liquid metals with great pressure, piston life is shortened, when vacuum die casting, air-tightness declines, and has the problems such as molten metal spills.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of die casting piston-cylinder, by design taper piston nose, effectively reduces molten metal and spills; By designing 3 ring sealing rings, guarantee the air-tightness of piston, improve service life; Cylinder arranged outside has thermal insulation tile and between the period of heating, realizes the insulation of liquid towards metal; Have that reliability is high, air-tightness good, long service life, good heat preservation performance, part replace the advantages such as convenient, cheap, has market prospects widely in compression casting industry simultaneously.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of die casting piston-cylinder is provided, comprises: piston, piston rod and cylinder, and described piston rear end is provided with piston rod, described piston and piston rod are arranged in cylinder, and described cylinder rear side upper end offers sprue.
In a preferred embodiment of the present invention, described cylinder arranged outside has heat insulation tile, is provided with heater in the middle of described cylinder and heat insulation tile.
In a preferred embodiment of the present invention, described piston rod is stepped stem, and piston rod front end is provided with screw thread.
In a preferred embodiment of the present invention, described piston rear end is provided with shoulder hole, after described shoulder hole, is provided with screwed hole.
In a preferred embodiment of the present invention, described piston nose is set to taper, and described taper angle is 110 °.
In a preferred embodiment of the present invention, described piston nose is provided with sealing ring, and described sealing ring is provided with 3 groups, is equidistant distribution, and sealing ring is copper.
The invention has the beneficial effects as follows: die casting of the present invention piston-cylinder, by design taper piston nose, effectively reduces molten metal and spills; By designing 3 ring sealing rings, guarantee the air-tightness of piston, improve service life; Cylinder arranged outside has thermal insulation tile and between the period of heating, realizes the insulation of liquid towards metal; Have that reliability is high, air-tightness good, long service life, good heat preservation performance, part replace the advantages such as convenient, cheap, has market prospects widely in compression casting industry simultaneously.
