Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy die casting technology, and in particular to a lubrication device for the cavity of an aluminum alloy die casting mold. Background Technology

[0002] Aluminum alloy die casting plays a vital role in modern manufacturing, with widespread applications in numerous fields such as automobiles, aerospace, and electronics. During the aluminum alloy die casting process, the lubrication of the mold cavity is crucial for improving casting quality, extending mold life, and ensuring production efficiency.

[0003] Existing aluminum alloy die-casting molds use lubricants during the die-casting process. Some traditional lubricants, such as grease, beeswax, and tallow, while low in cost, have limited lubrication effects and can easily lead to defects such as scratches and sticking to the mold surface, affecting product quality. Some lubricants contain environmentally harmful components, such as waste engine oil, which may generate harmful substances during use, posing a threat to the health of operators and the working environment, and also failing to meet environmental protection requirements. To address the drawbacks of the above technologies, we propose a cavity lubrication device for aluminum alloy die-casting molds. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a lubrication device for the cavity of an aluminum alloy die-casting mold.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lubrication device for the cavity of an aluminum alloy die-casting mold includes an operating table with a structural cover on its upper side. A lubrication assembly is mounted on the structural cover. The lubrication assembly includes an air pump and a conveying pipe. The air pump is fixedly installed on the upper side of the structural cover, and a vent pipe is fixedly installed on the output end of the air pump. A duct is connected to the lower end of the vent pipe and extends into the inner side of the structural cover, with the duct fixedly connected to the structural cover. A fixed cylinder is located below the duct, and a rotating shaft is rotatably mounted on the lower side of the fixed cylinder. An installation plate is fixedly mounted on the lower end of the rotating shaft, and several blades are fixedly mounted on the side of the installation plate. Several nozzles are evenly distributed at the bottom of the blades.

[0007] Furthermore, the inner end of the conveying pipe is connected to the inside of the fixed cylinder, and the fixed cylinder, the rotating shaft, the mounting plate and the inner side of the blade are all provided with cavities, which are interconnected, and the nozzle is connected to the cavity inside the blade.

[0008] Furthermore, the conveying pipe extends to the outside of the air duct, and a graphite lubricant storage tank and a conveying pump are fixedly installed on the upper side of the structural cover. The suction end of the conveying pump is connected to the graphite lubricant storage tank, and the output end of the conveying pump is connected to the outer end of the conveying pipe.

[0009] Furthermore, a feeding port is provided on the upper side of the graphite lubricant storage tank.

[0010] Furthermore, air outlets are provided on both sides of the structural cover, and dust filter screens are installed inside the air outlets.

[0011] Furthermore, several connecting rods are fixedly connected between the fixed cylinder and the inner wall of the flared hood.

[0012] Furthermore, a support frame is fixedly installed on the upper side of the operating platform, a controller is fixedly installed on the side wall of the support frame, an electric telescopic rod is fixedly installed at the bottom of the support frame, and the output end of the electric telescopic rod is fixedly connected to the structural cover.

[0013] Furthermore, an aluminum alloy die-casting mold is fixedly installed on the upper side of the operating platform, and the aluminum alloy die-casting mold is located directly below the structural cover.

[0014] Compared with related technologies, the aluminum alloy die-casting mold cavity lubrication device proposed in this utility model has the following beneficial effects:

[0015] In this invention, an aluminum alloy die-casting mold cavity lubrication device is described. Through a lubrication assembly, an air pump is activated to input air into a duct. The airflow in the duct drives blades, causing the mounting plate to rotate. Simultaneously, graphite lubricant is fed into the cavity inside the blades via a feed pipe, a fixed cylinder, a rotating shaft, and the mounting plate. This allows the graphite lubricant to be sprayed from a nozzle on the underside of the blades. The rotation of the blades ensures that the sprayed graphite lubricant is evenly dispersed onto the inner wall of the aluminum alloy die-casting mold, achieving uniform lubrication. The entire process is automated and highly efficient. Furthermore, this invention uses graphite lubricant, which offers advantages over traditional lubricants, including better lubrication, easier demolding, and less pollution, reducing harm to operators and making it highly practical.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Reference Figure 1-5 A lubrication device for the cavity of an aluminum alloy die-casting mold includes an operating table 1, a structural cover 6 on the upper side of the operating table 1, and a lubrication assembly 7 on the structural cover 6. The lubrication assembly 7 includes an air pump 71 and a material conveying pipe 76. The air pump 71 is fixedly installed on the upper side of the structural cover 6, and a vent pipe 72 is fixedly installed on the output end of the air pump 71. A duct 73 is connected to the lower end of the vent pipe 72. The duct 73 passes through the inner side of the structural cover 6 and is fixedly connected to the structural cover 6. A fixing cylinder is provided on the lower side of the duct 73. 78. A rotating shaft 710 is rotatably mounted on the lower side of the fixed cylinder 78. An installation plate 711 is fixedly mounted on the lower end of the rotating shaft 710. Several blades 712 are fixedly mounted on the side of the installation plate 711. Several nozzles 713 are evenly distributed on the bottom of the blades 712. The inner end of the conveying pipe 76 is connected to the inside of the fixed cylinder 78. Cavities are provided inside the fixed cylinder 78, the rotating shaft 710, the installation plate 711 and the blades 712. The cavities are interconnected. The nozzles 713 are connected to the inner cavities of the blades 712.

[0024] In this method, the conveying pipe 76 passes through to the outside of the air duct 73, and a graphite lubricant storage tank 74 and a conveying pump 75 are fixedly installed on the upper side of the structural cover 6. The suction end of the conveying pump 75 is connected to the graphite lubricant storage tank 74, and the output end of the conveying pump 75 is connected to the outer end of the conveying pipe 76. A feeding port is provided on the upper side of the graphite lubricant storage tank 74.

[0025] With the above configuration, when the feed pump 75 starts, it can draw the graphite lubricant stored in the graphite lubricant storage tank 74 into the inside of its working chamber, and then input it into the feed pipe 76 through the output end. After that, it is input into the nozzle 713 through the cavity inside the fixed cylinder, rotating shaft 710, mounting plate 711 and blade 712, thereby causing the graphite lubricant to be sprayed out from the nozzle 713.

[0026] In this method, air outlets 8 are provided on both sides of the structural cover 6, and a dust filter screen is installed inside the air outlet 8.

[0027] By using the above-mentioned setup, including the dust filter cover, graphite lubricant is prevented from being discharged from the air outlet 8, thus reducing air pollution in the production workshop.

[0028] In this method, a number of connecting rods 79 are fixedly connected between the fixed cylinder 78 and the inner wall of the flared hood 77.

[0029] With the above-described configuration, the connecting rod 79 provides a connection support point between the fixed cylinder 78 and the inner wall of the flared hood 77.

[0030] In this method, a support frame 2 is fixedly installed on the upper side of the operating table 1, a controller 3 is fixedly installed on the side wall of the support frame 2, an electric telescopic rod 5 is fixedly installed at the bottom of the support frame 2, the output end of the electric telescopic rod 5 is fixedly connected to the structural cover 6, and an aluminum alloy die-casting mold 4 is fixedly installed on the upper side of the operating table 1, and the aluminum alloy die-casting mold 4 is located directly below the structural cover 6.

[0031] With the above-mentioned setup, when the electric telescopic rod 5 is started, it can drive the structural cover 6 to move up and down, thereby enabling the structural cover 6 to cover the outside of the aluminum alloy die-casting mold 4.

[0032] The working principle of the aluminum alloy die-casting mold cavity lubrication device provided by this utility model is as follows:

[0033] In use, the controller 3 controls the electric telescopic rod 5 to drive the structural cover 6 to cover the outside of the aluminum alloy die-casting mold 4. Subsequently, the air pump 71 and the material pump 75 are started synchronously. Under the action of the air pump 71, the air duct 73 blows air into the inside of the structural cover 6. Under the action of the airflow, the blades 712 rotate, and the mounting plate 711 and the rotating shaft 710 rotate synchronously. Under the action of the material pump 75, the graphite lubricant in the graphite lubricant storage tank 74 is input into the material pipe 76. Subsequently, the graphite lubricant is input into the nozzle 713 through the cavity inside the fixed cylinder 78, the rotating shaft 710, the mounting plate 711 and the blades 712, and then the graphite lubricant is sprayed out from the nozzle 713. With the continuous rotation of the blades 712, the graphite lubricant is evenly sprayed onto the inner wall of the aluminum alloy die-casting mold 4 by several evenly distributed nozzles 713.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
