The utility model discloses a double X -axis engraving and milling machine with double four -axis linkage structure, including by the main part of engraving and milling machine, and in the main part of engraving and milling machine one side sets up the equipment main part of double four -axis station subassembly constitution, double four -axis station subassembly includes parallel alignment and set up's first four -axis main part and second four -axis main part, and is equipped with the docking slide for the cooperation processing product in the processing head opposite side of first four -axis main part and second four -axis main part, and the tail of first four -axis main part and second four -axis main part is connected with linkage subassembly, and linkage subassembly includes the linkage board of two ends respectively with the tail of first four -axis main part and second four -axis main part is connected, and with the vertical connection of linkage board's connecting rod, and the other end of connecting rod is equipped with driving arrangement, and linkage board passes through the cooperation of driving arrangement and connecting rod, makes first four -axis main part and second four -axis main part synchronous action. The utility model has solved the problem that single engraving and milling machine lacks double -shaft station (or more shaft) synchronous processing structure in prior art.

The utility model discloses a kind of mould locking pressurizing hydraulic circuit and die-casting machine, it is related to die-casting equipment technical field, including oil supply device, oil tank, pressurizing cylinder and mould locking cylinder;Pressurizing cylinder includes pressurizing oil inlet chamber, pressurizing oil return chamber and pressure building chamber;Oil supply device supplies oil to pressurizing oil inlet chamber and pressure building chamber, loop between pressurizing oil inlet chamber and pressure building chamber is equipped with first check valve;Pressure building chamber is communicated with mould locking cylinder rodless chamber;Pressurizing oil return chamber is communicated with oil tank, and oil passage between pressurizing oil return chamber and oil tank is equipped with first reversing valve;When the pressure of pressure building chamber reaches first pressure threshold, first reversing valve is powered to control the oil liquid of pressurizing oil return chamber flows into oil tank, so that the pressure of pressurizing oil inlet chamber is greater than the pressure of pressurizing oil return chamber, so that pressurizing piston rod is pressed into mould locking cylinder rodless chamber with the hydraulic oil of pressure building chamber.The scheme cancels accumulator, improves the pressure of mould locking cylinder under the precondition of not increasing system complexity and space requirement, can reduce cylinder diameter, reduce manufacturing and maintenance cost.
