Description

Technical Field

[0001] The utility model relates to the technical field of vibration molding, in particular to an automatic watering and cooling device for a vibration molding machine. Background Art

[0002] Vibration molding is a commonly used molding method, which is widely used in the production process of anode green bodies. By applying mechanical vibration force and other forces, the raw materials are plastically deformed in a specific mold to obtain the anode green blocks with the required shape.

[0003] During the vibration molding process, the vibration excitation force and the pressure generated by the heavy hammer will cause various stresses and deformations inside the green block. These stresses may cause minor looseness and outward expansion of the green block. In addition, after the green block is demolded, due to the elastic aftereffect of the material and the change of the external temperature, cracks may also appear on the surface of the anode green block.

[0004] To solve these problems, some measures can be taken to reduce the cracking rate of the anode green body and improve the qualified rate of the product. One important measure is to spray water on the anode green body in the mold in time after the vibration molding is completed. This can quickly cool the green body, slow down the elastic aftereffect of the material, and avoid or reduce the formation of cracks between the carbon bowls of the green block. In addition, spraying water for cooling also helps to stabilize the structure of the green body and improve the mechanical properties and overall quality of the product. The existing technology cannot automatically and precisely control the timing of spraying water for cooling and cannot accurately inject water into the anode carbon bowl. There is a risk that the cooling water is sprayed onto the surface of the metal mold, causing the high-temperature mold to cool suddenly and generating metal cracks.

[0005] The above information disclosed in the background art section is only used to enhance the understanding of the background of the utility model, and therefore may include information that does not constitute the prior art known to those of ordinary skill in the art.

[0041] As Figures 1-3 shown, in one embodiment, an automatic watering and cooling device for a vibration molding machine of the present utility model includes

[0042] a cooling water tank 1 that houses cooling water;

[0043] a circulating water pump 3 that is connected to the cooling water tank 1 through a pipeline to pump cooling water;

[0044] a solenoid valve 6 that is connected to and controls the on / off of the pipeline;

[0045] a displacement sensor that measures the weight displacement of the vibration molding machine;

[0046] a programmable controller that is connected to the displacement sensor and the solenoid valve 6 to generate a control signal for turning the solenoid valve 6 on and off based on the weight displacement;

[0047] a spray rack 8 that is connected to the pipeline through a connecting hose 7 to spray cooling water towards the anode green carbon bowl of the vibration molding machine. The spray rack 8 includes

[0048] a spray pipe 9 that communicates with the connecting hose 7,

[0049] a fixing member 13 that fixedly connects the spray pipe 9 to the mold 11 of the vibration molding machine,

[0050] At least one spray head, which is installed on the spray pipe 9 and can be adjusted in angle to spray cooling water towards the anodic green carbon bowl in the mold 11.

[0051] In a preferred embodiment of the automatic watering and cooling device for a vibration molding machine, a water inlet filter 2 is installed at the pipe opening in the cooling water tank 1.

[0052] In a preferred embodiment of the automatic watering and cooling device for a vibration molding machine, the pipe is provided with a pressure gauge 4 for measuring the pipe pressure.

[0053] In a preferred embodiment of the automatic watering and cooling device for a vibration molding machine, the pipe is provided with a pressure regulating valve 5 for regulating the pipe pressure.

[0054] In a preferred embodiment of the automatic watering and cooling device for a vibration molding machine, the spray head includes a universal joint bamboo pipe spray head 12 with an adjustable bending angle.

[0055] In a preferred embodiment of the automatic watering and cooling device for a vibration molding machine, the universal joint bamboo pipe spray head 12 includes a plurality of bamboo pipe units stacked in sequence.

[0056] In a preferred embodiment of the automatic watering and cooling device for a vibration molding machine, a plurality of the spray heads are arranged in an equidistant array on the spray pipe 9.

[0057] In a preferred embodiment of the automatic watering and cooling device for a vibration molding machine, the spray pipe 9 and the mold 11 are fixed together by fastening bolts 10 and fastening nuts 14.

[0058] In a preferred embodiment of the automatic watering and cooling device for a vibration molding machine, the spray pipe 9 can be moved and adjusted transversely to the mold 11.

[0059] In a preferred embodiment of the automatic watering and cooling device for a vibration molding machine, the fixing member 13 includes a flange.

[0060] In one embodiment, the spray rack 8 is located directly in front of the mold 11 of the vibration molding machine. The spray rack 8 is welded by steel pipes, and the left end and the right end of the spray rack 8 are parallel to the mold 11. The spray rack 8 can be reused by means of a detachable fixing member 13 along with the replacement of the mold 11.

[0061] In one embodiment, the automatic watering and cooling device of the vibration molding machine consists of a water pump, a host computer, an electromagnetic valve 6, a pressure regulating valve 5, a spray pipe 9, and a pressure gauge 4. The water pump pumps the cooling water in the cooling water tank 1 into the pipeline of the cooling water circulation and pressurizes the cooling water in the pipeline. Then, after the vibration molding machine completes the vibration molding, the pressing weight of the molding machine will rise. At this time, the displacement sensor detects the rise of the pressing weight and converts the displacement signal into an electric current signal and sends it to the programmable logic controller. After receiving the signal, the programmable logic controller sends a signal to the electromagnetic valve 6 installed on the cooling water pipe. At this time, the electromagnetic valve 6 opens, and the cooling water is sprayed into the anode green blank carbon bowl through the spray pipe 9. And a pressure regulating valve 5 is installed in the cooling water conveying pipeline to regulate the spraying pressure. The control of all the devices in this system is all carried out through the programmable logic controller, and the staff realizes the man-machine interaction through the host computer. After starting, this system can run automatically, which not only reduces the labor intensity of the operators, but also can achieve high-efficiency and high-quality production of products, realizing automatic spraying.

[0062] In one embodiment, the cooling water tank 1 and the circulating water pump 3 are connected and conducted through a pipeline. To maintain the normal water outlet pressure, the circulating water pump 3 is driven by a 22KW motor. At the same time, to prevent impurities from blocking the circulating water pipeline, a water inlet filter 2 is installed at the pipeline port in the cooling water tank 1. Then, an electromagnetic valve 6 is installed on the pipeline to control the water outlet process of the watering device. Finally, the spray head on the mold 11 is connected to the pipeline of the circulating cooling water by a hose.

[0063] In one embodiment, as Figure 2 shown, the spray pipe 9 and the mold 11 of the molding machine are fixed together by fastening bolts 10 and nuts. The spray head injects water for cooling into the anode green blank carbon bowl located in the mold 11 of the molding machine through four elbow pipes. And the elbow pipes of the spray head are designed to be adjustable structures. The purpose is that after replacing the mold 11 of the molding machine, different angles can be adjusted to adapt to different types of anodes, so that the cold water can be injected into the anode carbon bowl more accurately, avoiding the cooling water from being sprayed onto the surface of the metal mold 11, causing the sudden cooling of the high-temperature mold 11 and generating metal cracks. It has high practical value and can be applied to the manufacturing process of a variety of high-temperature demolding products. The automatic spraying reduces manual operation and improves the manufacturing quality.
