Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of piston ring preparation, and more specifically, to a piston ring vibrating shakeout screen. Background Art
[0002] The shakeout of piston rings is one of the important processes in the casting production process. That is, after the casting mold is poured and cooled to a certain temperature, the casting mold is broken to separate the casting mold from the sand mold and the piston ring from the sand material. Generally, a shakeout machine is selected to separate the piston ring from the sand material by vibration and impact.
[0003] The shakeout machines in the prior art can often only process a small amount of sand molds each time. Since the weight of a single sand mold is close to 12 kg, the labor intensity of personnel is relatively large during the process of transferring the sand molds. At the same time, after the piston ring is separated from the sand material, the sand material needs to be transported separately into the recycling system for reuse, which may cause problems such as sand material waste and environmental pollution. For the above reasons, when the piston ring is subjected to shakeout treatment, the whole process takes a long time and it is difficult to improve the production efficiency. Summary of the Utility Model

Through the dimensional fit between the sand mold and the shakeout cylinder, the casting mold can be easily separated from the sand mold without the need for personnel to transfer the sand mold into the shakeout machine, greatly reducing the labor intensity of personnel. And after the vibrating shakeout treatment, the sand material can directly fall into the sand material return channel, thus avoiding the phenomena of sand material waste and environmental pollution, greatly reducing the time required for the shakeout of piston rings, and effectively improving the production efficiency.

[0025] Embodiment 1:
[0026] Please refer to Figures 1-4, the piston ring vibrating shakeout screen, including a sand material return channel and a shakeout screen 1. Below the sand material return channel, there is a transport member for circulating the sand material. The shakeout screen 1 is arranged above the sand material return channel. At the geometric center of the shakeout screen 1, there is a connecting plate 101. A shakeout cylinder 2 is fixedly connected to the connecting plate 101. Discharge ports 201 are opened at both the front and rear ends of the shakeout cylinder 2. On the shakeout screen 1 and in the area outside the connecting plate 101, there is a screen mesh 102. On the inner wall of the sand material return channel, a pair of mounting seats 3 are fixedly connected. The pair of mounting seats 3 are respectively located directly below the front and rear ends of the shakeout screen 1. A pair of springs 4 are fixedly connected between the mounting seats 3 and the shakeout screen 1. A vibration motor 5 is installed at the lower end of the connecting plate 101. When the vibration motor 5 is started, the vibration force can be transmitted through the connecting plate 101 to the entire shakeout screen 1. And when the shakeout screen 1 vibrates, it continuously squeezes the springs 4. The springs 4 also continuously reset through the elastic force during this process. In the above process, the shakeout screen 1 and the springs 4 destroy the bonding force between the sand material and the piston ring inside the shakeout screen 1 through high-frequency vibration, making the sand material gradually loosen and separate from the surface of the piston ring. Above the shakeout cylinder 2, there is a sand mold 6 whose movement is controlled by a lifting fixture. The sand material return channel is arranged within the movable stroke range of the lifting fixture. After the sand mold 6 performs pouring and stacking operations, it can be directly transported above the shakeout screen 1 for shakeout treatment through the lifting fixture.
[0027] Please refer to Figures 3-4 , the inner diameter of the sand mold 6 is larger than the outer diameter of the shakeout cylinder 2, and the diameter of the casting in the sand mold 6 is smaller than the diameter of the shakeout cylinder 2. When performing shakeout treatment on the piston rings on multiple stacked sand molds 6, through the matching of their shapes, the casting can be easily separated from the sand mold 6. During this process, some of the sand material outside the sand mold 6 directly falls into the sand material return channel. Sieve holes 103 are formed on the screen mesh 102, and the diameter of the piston rings in the sand mold 6 is larger than the aperture of the sieve holes 103, which can prevent the piston rings from falling into the sieve holes 103 and also enable more sand material to quickly fall into the sand material return channel.
[0028] Please refer to Figure 1 and Figure 3 , the discharge ports 201 are opened at the positions on the shakeout cylinder 2 that are not connected to the connecting plate 101, and the height of the discharge ports 201 is not less than 10 cm. During the shakeout process, it is possible that the piston rings block the openings of the discharge ports 201. The discharge ports 201 with a height of not less than 10 cm provide an operating space for personnel to insert tools to dial the blocked and stacked piston rings, thereby increasing the separation speed of the piston rings and the sand material.
[0029] Please refer to Figure 1 and Figure 4 , all four sides of the shakeout screen 1 are set as inclined surfaces, and the inclination angle is 10 - 12°. After the piston ring shakeout treatment is completed, the inclined surfaces can effectively reduce the difficulty of removing the piston rings from the screen mesh 102.
[0030] When this device is in use, first, a hoisting fixture is used to clamp multiple stacked sand molds and control their slow descent along the outer wall of the knockout barrel. Due to the dimensional fit between the sand mold 6 and the knockout barrel 2, the casting mold can be easily separated from the sand mold 6, eliminating the need for personnel to transfer the knockout barrel 2 into the knock-out machine, significantly reducing the labor intensity of the personnel. Subsequently, a vibration motor 5 is used to vibrate and separate the sand material from the piston rings. After the vibration knock-out treatment, the sand material can directly fall into the sand material return channel, thus avoiding sand material waste and environmental pollution, greatly reducing the time required for piston ring knock-out, and effectively improving production efficiency.
[0031] The above is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and its improvement concept of the present invention, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
