Embodiment
Describe technical scheme in detail by the following examples, following embodiment be only it is exemplary, only
It can be used for explaining and illustrating technical solution of the present invention, and be not to be construed as the limitation to technical solution of the present invention.
The technical program provides a kind of quickly replacing mould structure 1, as shown in Figure 3 and Figure 4, including hydraulic cylinder 11, pressing plate
13rd, inlet valve 15, delivery valve 16, levelling valve 20, rotating shaft 14, the first oil inlet pipe 19, the second oil inlet pipe 18, the 3rd oil inlet pipe
22nd, the first flowline 21, the second flowline 17 and the 3rd flowline 23.
First oil inlet pipe 19 is connected with the oil inlet of levelling valve 20, and the first flowline 21 goes out with levelling valve 20
Hydraulic fluid port is connected.
Levelling valve 20 is connected with the lower end of rotating shaft 14；The upper end of rotating shaft 14 rotates with the lower end of hydraulic cylinder 11 and is connected.
The fluid chamber of L-type is provided with hydraulic cylinder 11, pressing plate 13 is provided with the front end of hydraulic cylinder, one end of pressing plate is lived
It is dynamic to be arranged in fluid chamber.
Second oil inlet pipe 18 is connected with the oil inlet of inlet valve 15；One end of 3rd oil inlet pipe 22 is fuel-displaced with inlet valve 15
Mouth connection, the other end of the 3rd oil inlet pipe 22 is connected with the oil inlet of hydraulic cylinder 11.
One end of second flowline 17 is connected with the oil-out of delivery valve 16, one end and the delivery valve 16 of the 3rd flowline 23
Oil inlet connection, the other end of the 3rd flowline is connected with the oil-out of hydraulic cylinder 11.
Hydraulic cylinder 11 is L-type, including cross edge and vertical edge portion；The lower end in vertical edge portion is connected with axis of rotation；Vertical edge portion
Upper end and one end of cross edge are connected；Pressing plate is arranged at the lower surface of the other end of cross edge.
Also include backing plate in the lower surface of pressing plate, the lower surface of backing plate is engaged with the surface of tight mould to be debugged.
In the application, it can be rotated between hydraulic cylinder and rotating shaft, hydraulic cylinder is by the pressure of hydraulic pressure by pressure transmission to pressure
Plate, by the cope plate or lower template of platen clamp mould to be debugged, rotating shaft and hydraulic cylinder can be controlled by levelling valve
Jack-up highly, levelling valve is fixed on lathe, and the top of levelling valve is adjusted by the oil pressure in the first oil inlet pipe
Height is played, the falling head of levelling valve is adjusted by the oil pressure in the first flowline.
After mould to be debugged is put on lathe, by rotating shaft rotating hydraulic cylinder and the horizontal level of pressing plate, it is transferred to rational
The lower template or cope plate of mould are clamped in position, adjusted by levelling valve between pressing plate and lower template or cope plate away from
From this distance can realize the preliminary clamping of mould when being less than 5mm by adjusting the thickness of backing plate 12.
After preliminary clamping, inlet valve is opened, hydraulic oil enters hydraulic pressure by the second oil inlet pipe, inlet valve, the 3rd oil inlet pipe
It is depressed into again on pressing plate in grease chamber, pressing plate is by a small amount of displacements by pressure transmission is to backing plate or is directly passed to lower template or upper mould
Plate, further clamps lower template or cope plate with lathe.
When needing to take apart a die, inlet valve is closed, the hydraulic oil opened in delivery valve, fluid chamber is fuel-displaced by the 3rd
Pipe, delivery valve and the discharge of the second flowline, the power that hydraulic oil is applied to pressing plate disappear, and rotating shaft rotates hydraulic cylinder to machine
Bed fore-and-aft direction parallel position, is easy to fork truck to produce lathe.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understand and these embodiments can be carried out without departing from the principles and spirit of the present invention a variety of changes, modification, replace
And deformation, the scope of the present invention extremely equally limits by appended claims.
