Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in further detail.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the composition relevant with this utility model.
(embodiment 1)
As shown in Figure 1 to Figure 3, the automatic die clamping device of the present embodiment includes housing 1 and is arranged on the first hydraulic cylinder 2 within housing 1, first piston the 3, second hydraulic cylinder the 4, second piston 5, spring 6, elastic component 7 and stopping means 8；
First hydraulic cylinder 2 and the second hydraulic cylinder 4 are respectively arranged with the first hydraulic fluid port 21 and the second hydraulic fluid port 41；
It is internal that first piston 3 is positioned at the first hydraulic cylinder 2, the piston rod of first piston 3 and the connection of the second hydraulic cylinder, first piston 3 be internally provided with the through hole along its piston rod direction, the second hydraulic fluid port 41 of this through hole and the second hydraulic cylinder 4 connects；
It is internal that second piston 5 is positioned at the second hydraulic cylinder 4, and the other end of the piston rod of the second piston 5 is provided with compression boss 51；
It is provided with block rubber 71 between second piston 5 and the second hydraulic cylinder 4；
It is provided with spring 6 between second hydraulic cylinder 4 and housing 1；
Second hydraulic cylinder is internally provided with spacing preiection 81, and spacing preiection 81 limits the stroke of the second piston 5, controls the second piston 5 not across the second hydraulic fluid port 41.
The automatic die clamping device of the present embodiment is arranged on the surface of die bottom plate 9, figure it is seen that the edge of die bottom plate 9 and mould 10 all offers the groove of one section of longitudinal direction；When starting to be filled with hydraulic medium in the first hydraulic cylinder 2, first piston 3 drives the second hydraulic cylinder 4 to move right, and this stage second piston 5 does not move due to the effect of block rubber 71；When first piston 3 walks to low order end, the piston rod of the second piston 5 enters in the groove at die bottom plate 9 and mould 10 edge, pressure in two hydraulic cylinders continues to rise, second piston 5 extrudes block rubber 71 and moves upward, mould 10 is pressed on die bottom plate 9 by the compression boss 51 of the second piston 5 piston-rod lower end, completes mold cramping.During dismounting, removing the fluid pressure in two hydraulic cylinders, the second piston 5 unclamps mould 10 automatically, and spring 6 promotes the second hydraulic cylinder 4 to leave mould 10 with the second piston 5, facilitates follow-up equipment more mold exchange 10.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not necessarily departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content in description, it is necessary to determine its technical scope according to right.
