An overflow plate 14 is fixedly provided inside the recovery basin 9. The oily release agent floating on the water surface is overflowed into the cavity on the other side through the overflow plate 14.

[0029] In this embodiment, a pump is installed inside the spray pump housing 41, and a nozzle 45 is connected to the bottom end of the horizontal pipe 44. The pump draws water and sprays it through the nozzle 45. A micro motor 46 is fixedly installed on the outside of the spray pump housing 41. A drive bevel gear 47 is fixedly installed at the end of the main shaft of the micro motor 46. A driven bevel gear 48 fixed to the connecting pipe 43 meshes with the outside of the drive bevel gear 47. The micro motor 46 drives the gear transmission and controls the horizontal pipe 44 to rotate.

[0030] A housing 5 is fixedly installed on the upper right side of the main body 1. A hose 7 is fixedly installed at the bottom of the housing 5. A floating suction head 8 located inside the recovery basin 9 is fixedly installed at the other end of the hose 7. The floating suction head 8 floats on the liquid surface to recover the oily release agent. A square tube 10 is connected to the left side of the recovery basin 9. A threaded tube 11 is connected to the top of the square tube 10. An L-shaped tube 12 fixed to the inclined plate 13 is connected to the other end of the threaded tube 11. The L-shaped tube 12 is connected to the threaded tube 11. An interceptor plate 15 is slidably installed inside the overflow plate 14.

[0031] The main body 1, servo transmission frame 3, and micro motor 46 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail.

The appropriate model is selected based on actual use; therefore, the control method and wiring layout of the motor will not be explained in detail.

[0032] Working principle and process of a spraying equipment for aluminum alloy die-casting parts:

[0033] Workers inject an oil-based release agent into the casing 5 outside the machine body 1 for storage, connecting it to the internal diffusion spraying assembly 4. The spraying pump housing 41 is driven by a servo drive frame 3 below the machine top 2. During movement, a micro motor 46 on the outside of the spraying pump housing 41 operates, driving the active bevel gear 47 at the end of the main shaft to rotate. This meshes with the driven bevel gear 48 on the outside, causing the universal joint 42 and connecting pipe 43 to rotate. The horizontal pipe 44 can rotate above the spraying plate 6 for spraying. Using an oil-based release agent more effectively reduces the contact between the mold and the molten aluminum alloy. The friction and adhesion between the components are reduced, and the increased horizontal tube 44 structure can improve the spraying range and speed up the spraying efficiency of the oily release agent. The design of multiple nozzles 45 speeds up the spraying efficiency. The oily release agent that drips into the lower inclined plate 13 enters the recovery basin 9 connected to the square tube 10 along the L-shaped tube 12 and the threaded tube 11. It overflows through the water flow. According to the spraying progress, the height of the stretching interceptor plate 15 is adjusted, and the filter screen 16 is used to separate the impurities inside the oily release agent to prevent it from being sucked in. The floating suction head 8 sucks the oily release agent into the hose 7 through the pump structure and enters the interior of the box 5 for secondary use.
