The invention discloses rapid die casting equipment for aluminum alloy die castings, and relates to the technical field of metal die casting. A first channel is formed in a die plate and an ejector rod, and a spray hole communicating with the first channel is formed in the ejector rod; according to the device, the mold release agent can be sprayed to the relatively-closed die-casting cavity in a mold closing state, the comprehensive uniformity of the mold release agent during adhesion is improved, the demolding effect after a die casting is formed is improved, the mold release agent is sprayed in the relatively-closed die-casting cavity, and the mold release effect is improved. According to the die-casting mold core, the release agent can be prevented from escaping outwards, the surrounding environment can be protected easily, waste of the release agent can be avoided, energy-saving, environment-friendly, green and efficient die-casting production is achieved, meanwhile, the spraying holes are formed in the cylindrical face of the end of the ejector rod, the spraying holes cannot be exposed when the ejector rod retracts into the die core, and the die-casting mold core is more environment-friendly. And interference to die-casting production due to the fact that the spraying holes are exposed in the die-casting cavity can be avoided.

The invention discloses a high-performance fluid oscillator based on a turbulent flow column structure. The high-performance fluid oscillator comprises an oscillator body, and the oscillator body is provided with a fluid oscillator inlet, an oscillator inlet channel, a mixing chamber, a mixing chamber inlet, a mixing chamber outlet, a feedback channel, a feedback channel inlet, a feedback channel outlet, an oscillator outlet channel, a fluid oscillator outlet and turbulent flow columns; the fluid oscillator inlet is communicated with the oscillator inlet channel; the oscillator inlet channel is communicated with the feedback channel outlet and the mixing chamber inlet; the mixing chamber inlet is communicated with the mixing chamber; the mixing chamber is communicated with the mixing chamber outlet, the feedback channel inlet and the oscillator outlet channel; and a unique turbulent flow column structure is arranged at the rear end of the oscillator outlet channel. The device does not need extra power, utilizes the Coendall effect, the backflow feedback effect and the Karman vortex street effect of the airflow to generate periodic large-amplitude up-and-down swinging airflow at an outlet of the device, and is simple in structure, small in size, large in jet flow deflection angle, convenient to operate, reliable in running and free of maintenance.

The utility model discloses a sliding table for a deep hole drilling machine tool, which comprises a sliding table main body, the sliding table main body comprises a supporting seat, a rotating shaft and a supporting table are arranged on the supporting seat, a worm and a hand wheel are rotatably arranged on the supporting seat, a worm gear is arranged on the rotating shaft, sliding rails are symmetrically arranged on the supporting table, and sliding blocks are arranged on the sliding rails. A plurality of lubricating grooves are formed in the sliding rail, an oil injection plate and an oil injection air bag are arranged in each lubricating groove, an oil outlet hole and an oil outlet groove are formed in the top of each lubricating groove, an air supplementing device is arranged on the sliding rail, a worm and a worm gear are driven to rotate through a hand wheel, the rotating shaft and the supporting table are conveniently driven to rotate, and then the rotating angle of the sliding table body is adjusted. The oil injection air bag extrudes the oil injection plate, the position of the oil injection plate is adjusted, the oil injection plate moves to extrude lubricating oil to move upwards, the lubricating oil flows to the sliding rail through the oil outlet hole and the oil outlet groove, the sliding block and the sliding rail are lubricated, and abrasion is reduced.
