The utility model has simple structure and reasonable design; the two hydraulic cylinders with the same cylinder diameter are serially connected by the cylinder lever and the solenoid valve controls an oil circuit, so that the two hydraulic cylinders displace and run synchronously, so as to make sure the upper and the lower boxes are synchronous when being combined or separated, improve the production efficiency and ensure the continuity of the production process.
Description
Technical field
The utility model belongs to the Casting Equipment field, and the upper and lower case of particularly a kind of moulding machine is with the moved further hydraulic means.
Background technology
In foundry production, need top box and nowel are carried out mould assembling before penetrating sand, also will be separately after sand mo(u)ld is shaped with top box and nowel.On the cylinder bar that top box in the existing moulding machine and nowel are packed in two hydraulic cylinders respectively,, thereby realize that the mould assembling of upper and lower case or branch mailbox move by the cylinder bar motion of two hydraulic cylinders of solenoid control.Two present hydraulic cylinders are respectively by two solenoid control, and by adding the translational speed of two hydraulic cylinders of flow speed control valve control.Because the regulated quantity of flow speed control valve is bigger, accurate inadequately, therefore two hydraulic cylinders are difficult to accomplish synchronization action, cause top box and nowel exercise not harmony when carrying out mould assembling or branch mailbox synchronous, thereby have influenced the continuity of production process, have reduced production efficiency.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of and can improve the accuracy and the synchronism of moving when upper and lower case carries out mould assembling or branch mailbox, guarantee the continuity of production, the upper and lower case of the moulding machine of enhancing productivity is with the moved further hydraulic means.
The utility model solves its technical problem and takes following technical scheme to realize:
On a kind of moulding machine, nowel is with the moved further hydraulic means, by motor, hydraulic pump, the top box hydraulic cylinder, the nowel hydraulic cylinder and first magnetic valve constitute, hydraulic pump is communicated with first magnetic valve by motor-driven and by pipeline, it is characterized in that: the top box hydraulic cylinder is connected by a cylinder bar that is fixed in ground with the nowel hydraulic cylinder, the left chamber of the left chamber of top box hydraulic cylinder and nowel hydraulic cylinder passes through pipeline connection, the A1 port of first magnetic valve is communicated with the right chamber of nowel hydraulic cylinder by pipeline, and the B1 port of first magnetic valve is communicated with the right chamber of top box hydraulic cylinder by pipeline.
And described hydraulic pump also connects one second magnetic valve, and the A2 port of this second magnetic valve is communicated with the left chamber of top box hydraulic cylinder and nowel hydraulic cylinder.
And the B2 port of described second magnetic valve is communicated with the A1 port of the nowel hydraulic cylinder and first magnetic valve.
Advantage of the present utility model and good effect are:
1. the upper and lower case of this moulding machine is together in series by a cylinder bar with the hydraulic cylinder of moved further hydraulic means with two identical cylinder diameters, and an end of this cylinder bar fixes on the ground, and by first magnetic valve its oil circuit is controlled.Because system pressure is not high, so the interior leakage of hydraulic cylinder is not serious, reached two hydraulic cylinder displacement synchronous operations, guaranteed top box and the nowel synchronism when mould assembling or branch mailbox.
2. what the raising of branch mailbox and mould assembling action synchronism can guarantee to produce carries out continuously, enhances productivity effectively.
3. increased by one second magnetic valve in the utility model, this magnetic valve can be realized the demoulding action before the upper and lower case branch mailbox, thus refinement the action of entire mechanism, make the operation of entire mechanism more accurate.
4. the utility model is simple in structure, reasonable in design, be together in series with a cylinder bar by hydraulic cylinder two identical cylinder diameters, and use magnetic valve that its oil circuit is controlled, two hydraulic cylinder displacement synchronous operations have been reached, guaranteed top box and the nowel synchronism when mould assembling or branch mailbox, improve production efficiency, guaranteed the continuity of production process.
Description of drawings
Fig. 1 is a front view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
The upper and lower case of this moulding machine is made of motor 6, hydraulic pump 7, top box hydraulic cylinder 3, nowel hydraulic cylinder 1 and first magnetic valve 5 with the moved further hydraulic means, and hydraulic pump is by motor-driven, and is communicated with the supply that realizes pressure oil by pipeline 4 with first magnetic valve.
Of the present utility model being characterised in that: the top box hydraulic cylinder is connected by a cylinder bar 2 that is fixed in ground with the nowel hydraulic cylinder, the left chamber of the left chamber of top box hydraulic cylinder and nowel hydraulic cylinder passes through pipeline connection, the A1 port of first magnetic valve is communicated with the right chamber of nowel hydraulic cylinder by pipeline, and the B1 port of first magnetic valve is communicated with the right chamber of top box hydraulic cylinder by pipeline.
Hydraulic pump also connects one second magnetic valve 8, and the left chamber of the A2 port of this second magnetic valve and top box hydraulic cylinder and nowel hydraulic cylinder passes through pipeline connection.The B2 port of second magnetic valve is communicated with the A1 port of the nowel hydraulic cylinder and first magnetic valve.
Operation principle of the present utility model is:
Driven by motor hydraulic pump pressure oil output is supplied with first magnetic valve and second magnetic valve.
(1). after the 2CT energising, the B1 mouth pressure oil output of first magnetic valve is to the right chamber of top box hydraulic cylinder.Because the cylinder bar is fixing immovable, so the top box hydraulic cylinder moves to branch mailbox direction (being the I direction).Thereby the hydraulic oil in the top box hydraulic cylinder left chamber is forced to be transported in the left chamber of nowel hydraulic cylinder, and it is also mobile towards branch mailbox direction (being the I direction) to promote the nowel hydraulic cylinder, has realized the branch mailbox action with this.
(2). after the 3CT energising, the A1 mouth pressure oil output of first magnetic valve is to the right chamber of nowel hydraulic cylinder.The nowel hydraulic cylinder moves to mould assembling direction (being the II direction), and makes hydraulic oil in the nowel hydraulic cylinder left chamber be transported to the left chamber of top box hydraulic cylinder, makes the top box hydraulic cylinder also move towards mould assembling direction (being the II direction), has therefore realized the mould assembling action.
(3). after the 1CT energising, the A2 mouth pressure oil output of second magnetic valve makes the nowel hydraulic cylinder move towards the branch mailbox direction to nowel hydraulic cylinder left chamber, has realized that therefore the demoulding before the upper and lower case branch mailbox is moved.
