The utility model provides a semi-automatic hydraulic moulding machine, comprising a machine body, a working bench, a rotary rocking arm, a vibration device, a compactor and a die lifter. Wherein, the air inlet pipe of a vibration cylinder in the vibration device is connected with a compressed air inlet pipe through an electromagnetic air valve; a compacting oil cylinder in the compactor is connected with an oil pump through a compacting descending electromagnetic valve and a compacting ascending electromagnetic valve. In the die lifter, a die lifting oil cylinder is connected with the die lifting cantilever beam through a lever, and the die lifting oil cylinder is connected with the oil pump through a die lifting electromagnetic valve; a control circuit controls the vibration device, the compactor and the die lifter to work through an intermediate relay, a time relay and an electromagnetic valve. The utility model has the advantages of simple operation, vibration, uniform compaction, stable die lifting, fast production rate, high qualified rate of the products, etc, which is very suitable for the box moulding of the medium casting and the box moulding of the small casting and the box with multi dies. The successful development of the product reduces the productive cost of the casting factory, which is suitable for the need of the development of the modern casting industry.
