Abstract

The utility model discloses a composite hydraulic jack of a molding machine. The composite hydraulic jack comprises a first hydraulic cylinder and a second hydraulic cylinder, wherein the second hydraulic cylinder is provided with a piston rod, the piston rod penetrates through the first hydraulic cylinder and is provided with a piston, and the piston is arranged inside the first hydraulic cylinder; the upper part of the first hydraulic cylinder is provided with a descending hydraulic port, and the lower part of the first hydraulic cylinder is provided with an ascending hydraulic port; the piston rod is provided with a descending hydraulic pipe for communicating the first hydraulic cylinder with the second hydraulic cylinder, and the first hydraulic cylinder is also communicated with the second hydraulic cylinder through an ascending hydraulic pipe; one end of the descending hydraulic pipe is arranged on the upper part of the piston; one end of the ascending hydraulic pipe is arranged on the bottom of the second hydraulic cylinder, and the other end of the ascending hydraulic pipe is arranged on the bottom of the first hydraulic cylinder; the top of the first hydraulic cylinder is provided with a mold, and a mold plate is arranged above the mold. The composite hydraulic jack has the advantages that a sand mold compacting step and a mold stripping step can be simultaneously completed, and the compactness of a sand mold is moderate and uniform.

Description

The moulding machine complex liquid bears down on one
Technical field
The utility model relates to a kind of moulding machine, and specifically a kind of moulding machine complex liquid bears down on one, and belongs to the foundry machinery field.
Background technology
Hydraulic top in moulding machine can make husky compacting and stripping pattern.Traditional moulding machine is general adopts two hydraulic tops to finish the work, and adopts the shortcoming of this equipment to have the sandbox tight ness rating lower, and even not, complex operation step, inefficiency.
Summary of the invention
In order to address the above problem, the utility model has designed a kind of moulding machine complex liquid and has beared down on one, and can complete two operations of sandbox compacting and stripping pattern simultaneously, sandbox tight ness rating appropriateness, and more even.
The technical solution of the utility model is:
A kind of moulding machine complex liquid bears down on one, and comprises the first hydraulic cylinder and the second hydraulic cylinder, and described the second hydraulic cylinder is provided with piston rod, and described piston rod is through described the first hydraulic cylinder, and described piston rod is provided with piston, and described piston is positioned at described the first hydraulic cylinder; The top of described the first hydraulic cylinder is provided with the decline hydraulic port, and bottom is provided with the rising hydraulic port; Described piston rod is provided with the decline hydraulic tube that is communicated with described the first hydraulic cylinder and the second hydraulic cylinder, between described the first hydraulic cylinder and the second hydraulic cylinder, also by the rising hydraulic tube, is connected; One end of described decline hydraulic tube is positioned at piston top; One end of described rising hydraulic tube is positioned at the bottom of described the second hydraulic cylinder, and the other end is positioned at the bottom of described the first hydraulic cylinder; Described the first hydraulic cylinder top is provided with mould, and described mould top is provided with Die and mould plate.The sandbox mould is installed on Die and mould plate, and sandbox is placed in the mould top, and the sandbox top is provided with fixing iron plate, by the hydraulic top top sandbox that makes progress, makes the sand moulding.
Further, between described mould and Die and mould plate, be provided with spring, described spring is provided with adjusting nut, and adjusting nut is used for regulating the height of Die and mould plate, to be applicable to the mould of differing heights;
In addition, described piston rod is provided with fairlead, and fairlead can make hydraulic top more stable, not there will be integral body to rock.
The rising hydraulic port is carried out hydraulic pressure to the first hydraulic cylinder top, continues to enter the second hydraulic cylinder by the rising hydraulic tube after hydraulic pressure, makes piston rod increase, and completes extruding upwards.By realizing the function of twice compacting, make sandbox tight ness rating appropriateness, integral body is more even: for the first time, after sandbox places, mould rises, the Die and mould plate fine motion; For the second time, piston to the first hydraulic cylinder top, the second hydraulic cylinder enters hydraulic pressure, and mould and Die and mould plate are risen overally, and completes secondary extrusion.The decline hydraulic port enters hydraulic pressure, make piston drop to the first hydraulic cylinder bottom, hydraulic pressure enters the second hydraulic cylinder through the decline hydraulic tube, piston rod is descended, together with mould and the whole decline of Die and mould plate, complete sandbox, due to spring being housed in Die and mould plate, in the process descended, make mould retention time in sandbox long, and can slow decreasing, sandbox is more complete.
The utility model has the advantage of: can complete two operations of sandbox compacting and stripping pattern simultaneously, sandbox tight ness rating appropriateness, and more even.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model embodiment;
In figure: 1-the first hydraulic cylinder, 2-the second hydraulic cylinder, 3-piston, 4-rising hydraulic tube, 5-decline hydraulic tube, 6-piston rod, 7-decline hydraulic port, 8-rising hydraulic port, 9-mould, 10-adjusting nut, 11-Die and mould plate, 12-spring, 13-fairlead.
