Abstract
The utility model relates to a multistation plane extrusion hydro-cylinder has the connecting plate, the connecting plate on install the different little hydro-cylinder of three bore, three little hydro-cylinder axis is parallel to each other, little hydro-cylinder all have the cylinder, with cylinder inner wall sliding fit's piston, with the piston rod that the piston links firmly and fix the end cover at the cylinder front end, it is equipped with the hydraulic fluid port to correspond on the cylinder, before the connecting plate is located the end cover, wear to be equipped with the connecting bolt with connecting plate threaded connection from the cylinder rear end. The utility model discloses a connecting plate is with the little hydro-cylinder combination of three different cylinder diameters integrative, constitutes an extrusion hydro-cylinder that accords with die casting die special space requirement, and three little hydro-cylinder mutually noninterfere can independently carry out reciprocating motion separately, also can the simultaneous movement, realizes under the limited situation in mould space, accomplishes the extrusion to the different position gas pockets of die casting jointly, improves the die casting quality.
Description
Technical Field
The utility model relates to a used multistation plane extrusion hydro-cylinder of die casting technology.
Background
In the die casting process, due to the non-uniformity of die casting products, air holes are inevitably generated when aluminum water is injected into a die to influence the quality of die castings, so that the air holes are usually eliminated by adopting an extrusion oil cylinder in the die casting process, but due to the irregularity of the die, a plurality of air holes can be formed on one plane, a good effect cannot be achieved by adopting a single extrusion oil cylinder, and in addition, due to the limited internal space of the die, a plurality of required extrusion oil cylinders are inconvenient to be installed in the die at one time.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: in order to overcome the defects in the prior art, the utility model provides a multi-station planar extrusion oil cylinder which can eliminate multiple air holes at one time.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a multistation plane extrusion hydro-cylinder, has the connecting plate, the connecting plate on install the different little hydro-cylinder of three bore, three little hydro-cylinder axis is parallel to each other, little hydro-cylinder all have the cylinder, with cylinder inner wall sliding fit's piston, with the piston rod that the piston links firmly and fix the end cover at the cylinder front end, correspond on the cylinder and be equipped with the hydraulic fluid port, the connecting plate is located before the end cover, wear to be equipped with the connecting bolt with connecting plate threaded connection from the cylinder rear end.
Furthermore, in order to improve the smoothness of the piston rod, a guide sleeve is arranged between the end cover and the piston rod.
The utility model has the advantages that: the utility model discloses a connecting plate is with the little hydro-cylinder combination of three different cylinder diameters integrative, constitutes an extrusion hydro-cylinder that accords with die casting die special space requirement, and three little hydro-cylinder mutually noninterfere can independently carry out reciprocating motion separately, also can the simultaneous movement, realizes under the limited situation in mould space, accomplishes the extrusion to the different position gas pockets of die casting jointly, improves the die casting quality.
Drawings
The present invention will be further described with reference to the accompanying drawings and embodiments.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural view of the small oil cylinder of the present invention.
In the figure: 1. the hydraulic cylinder comprises a connecting plate, 2 parts of a small oil cylinder, 2-1 parts of a cylinder barrel, 2-2 parts of a piston, 2-3 parts of a piston rod, 2-4 parts of an end cover and 2-5 parts of a guide sleeve.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
The multi-station planar extrusion oil cylinder shown in the figures 1 and 2 is provided with a connecting plate 1, three small oil cylinders 2 with different cylinder diameters are mounted on the connecting plate 1, the axes of the three small oil cylinders 2 are parallel to each other, each small oil cylinder 2 is provided with a cylinder barrel 2-1, a piston 2-2 in sliding fit with the inner wall of the cylinder barrel 2-1, a piston rod 2-3 fixedly connected with the piston 2-2 and an end cover 2-4 fixed at the front end of the cylinder barrel 2-1, oil ports are correspondingly formed in the cylinder barrel 2-1, and a guide sleeve 2-5 is arranged between the end cover 2-4 and the piston rod 2-3.
The connecting plate 1 is positioned in front of the end cover 2-4, and a connecting bolt in threaded connection with the connecting plate 1 penetrates through the rear end of the cylinder barrel 2-1.
The utility model discloses a connecting plate 1 makes up into an organic whole with the little hydro-cylinder 2 of three different cylinder diameters, constitutes an extrusion hydro-cylinder that accords with the special space requirement of die casting die, and three little hydro-cylinder 2 mutually noninterferes can independently carry out reciprocating motion separately, also can the simultaneous movement, realizes under the limited situation in mould space, accomplishes the extrusion to the different position gas pockets of die casting jointly, improves the die casting quality.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
