摘　　要：针对压射启动时实时控制型压铸机压射缸锤头前冲,使熔融金属在锤头的推动下从金属浇注口处溢出的问题,提出对压射缸由杆腔预增压的方案以消除启动冲击,针对该方案设计出增压阀,并对该方案进行了仿真和试验验证。For real time controlling the preshoot of the injection cylinder hammerhead of the die casting machines when injection starts,the problem caused by the molten metal to overflow the metal pouring mouth pushed by the hammerhead,the scheme that the injection cylinder will be pre-pressurized by the rod cavity is proposed to eliminate the start-up impact.The pressure boosting valve is designed and the simulation and verification by test is carried out according to this scheme.

关 键 词：实时控制 启动冲击 预增压
