Along with continuously the development of extrudes technical, The Continuous Extrusion Machinery has become one of indispensably equipment in the material process enterprise. Continuously extrudes/the continual gable is the principle which transforms using the friction heat energy the aluminum, the copper direct extrusion tubing, the molding or the gable product. Compares with the traditional process, this technology has the productivity high, the energy consumption low, the material use factor high, the product quality is good and so on a series of merits. This new technology overcame the traditional extrusion method productivity lowly, the quality has been bad, the product variety few shortcomings, at present by obtains the widespread application.Regarding the continual extruder, its shoes place lock mold hydraulic system can directly affect the product the quality and the production efficiency, therefore, how can the precise locking extruder shoes place and fast replaces the mold to change extremely importantly. super-pressure hydraulic pressure automatic reverse pressure intensifier is one kind of ultrahigh voltage hydraulic pressure increases the strength installment, may effectively reduce the pressurizing unit the external dimensions, and enhancement output load strength. In the structural design, causes the turbo-charged cavity to isolate with exterior low pressure return route, uses the special reversing gear realization movement part the automatic reverse forced reversing. After entire hydraulic pressure automatic reverse forced reversing structure determination, increases the strength installment in view of this kind of ultrahigh voltage entire hydraulic pressure automatic reverse forced reversing the parameter design and the optimized sound of something astir condition characteristic question is especially important.The thesis used SIMULINK toolbox in the MATLAB7.1, has carried on the simulation analysis on the computer to the system dynamic characteristic, especially analyzed the entire hydraulic pressure automatic reverse forced reversing pressure intensifier dynamic characteristic, has divulged, the load to the system performance influence. The realization to this hydraulic system dynamic response simulation, obtained has output the cylinder various spots the pressure, the speed, the displacement diagram, and carried on to the output result in detail has analyzed: At the same time, the change outputs the cylinder the size parameter and carries on the analysis, Tabulates the contrast each kind of analysis result, had achieved the design parameter optimizes goal, thus for lock mould hydraulic system the dynamic characteristic to make the correct appraisal, for hydraulic system and pressure intensifier design. To enhances the super-pressure hydraulic pressure automatic reverse pressure intensifier the design and locks the mold fluid system the improvement, has provided a more scientific basis.
