Oil-hydraulic cylinder upper end, which has, is provided with piston body in opening, the plunger shaft, the piston body upper end is fixedly connected with push rod, institute
Push rod is stated in the opening, back-moving spring, described body sidewall are provided between the piston body and the oil-hydraulic cylinder
The oil inlet connected with the plunger shaft bottom is provided with, the push rod when the piston body is located at the plunger shaft lowest part
Upper end, which is higher than to rotate on the oil-hydraulic cylinder, the body, is provided with pressing plate, and the pressing plate side is located above the push rod, position
Pressing plate bottom above the push rod is provided with the recess for preventing that pressing plate from colliding with oil-hydraulic cylinder.Passed through using this structure
Hydraulic oil is passed through in oil inlet so that piston body is moved up, push rod upper end is withstood pressing plate and moved up, the opposite side of pressing plate, which is pushed, pushes down mould
Tool, so that the quick positioning of mould is realized, when needing to unclamp mould, to hydraulic oil pressure release, work of the piston body in back-moving spring
Moved down under, pressing plate is no longer influenced by the power of push rod to unclamp mould.
It is described recessed in above-mentioned technical proposal, it is preferred that set fluted on the body below the pressing plate opposite side
Spring is vertically arranged with groove, the spring upper end is contacted by spring cup with the pressing plate.Caused using the structure in hydraulic pressure
After oily pressure release, the spring causes pressing plate to be returned to initial position, so that more easily more mold exchange.
In above-mentioned technical proposal, it is preferred that the piston body side surface is provided with first annular groove, the first annular groove
It is provided with first seal.The sealing between piston body and oil-hydraulic cylinder is caused to improve using the structure.
In above-mentioned technical proposal, it is preferred that the oil-hydraulic cylinder is the cylindrical part that upper end has opening, the cylindrical part
Part, which is embedded in the groove of the body, forms plunger shaft, and the cylindrical part side is provided with the second annular groove, second annular
Second seal is provided with groove.Facilitate the installation of piston body using the structure, set second seal improve cylindrical part with
The sealing of body.
The utility model compared with prior art, has the advantages that：Passed through using this structure logical in oil inlet
Enter hydraulic oil so that piston body is moved up, push rod upper end is withstood pressing plate and moved up, the opposite side of pressing plate, which is pushed, pushes down mould, so as to realize
The quick positioning of mould, when needing to unclamp mould, to hydraulic oil pressure release, piston body is moved down in the presence of back-moving spring, pressure
Plate is no longer influenced by the power of push rod to unclamp mould.
