Description

Technical Field

[0002] The high-speed motor core is the core component of the high-speed motor. The core is also the magnetic core. The high-speed motor core is injection molded by a mold during processing and production. When the mold is injection molding the high-speed motor core, the guide column needs to be lubricated. Usually, a lubrication structure is installed for lubrication. The existing lubrication structure is a device used for lubricating the guide column of the high-speed motor core processing mold. The lubrication structure is easy to disassemble and operate quickly during use. After installation, it is convenient to evenly inject oil for lubrication, thereby improving the convenience and uniformity of lubrication when the mold lubrication structure is installed on the high-speed motor core mold.

[0003] When the existing lubrication structure is installed on the high-speed motor core mold to lubricate its guide column, a sponge is installed on the inner surface of the lubrication structure to introduce lubricating oil. When the guide column is in the inner surface of the lubrication structure for lubrication, the guide column directly touches and squeezes the surface of the sponge to lubricate it, and long-term squeezing and lubricating of the sponge can easily cause damage to the sponge. It is inconvenient to replace the damaged sponge and increase the cost. At the same time, it is not convenient to uniformly lubricate the oil, which affects the convenience and uniformity of the lubrication structure installed on the high-speed motor core mold. For this reason, the utility model proposes a high-speed motor core mold lubrication structure. Utility Model Content

Guide holes 104 are opened at the four corners of the upper surface of the lower mold base 101, and a lubrication cylinder 105 is provided at the top end of the guide hole 104. An oil storage tank 107 is provided at the inner edge of the lubrication cylinder 105. An oil inlet is provided on one side of the top end of the lower mold base 101, and mounting grooves 106 are equidistantly opened at the bottom edge of the inner surface of the lubrication cylinder 105. When the mold lubrication structure main body 100 is in use, the guide pillars 103 are engaged with the guide holes 104 so that the guide pillars 103 pass through the interior of the lubrication cylinder 105, which is convenient for lubricating the guide pillars 103 inside the lubrication cylinder 105. The mold lubrication structure main body 100 is also provided with:

[0026] A uniform oil injection lubrication mechanism includes an oil immersion component arranged on one side of the mounting groove 106, a uniform rolling oil injection component is arranged on the side of the oil immersion component located on the other side of the mounting groove 106, and an elastic connection component is arranged at the end of the uniform rolling oil injection component, which is convenient for lubricating the guide column 103 in the lubrication cylinder 105, and uniformly injecting oil and lubricating the outer surface of the guide column 103, which is not easy to cause direct squeezing and touching the sponge and is convenient for lubrication, thereby improving the convenience and uniformity of lubrication when the mold lubrication structure main body 100 is installed on the high-speed motor core mold.

[0027] In order to facilitate the oil immersion lubrication treatment when the lubricating ball 1063 is pressed against the connecting plate 1062 through the oil immersion component, in this embodiment, preferably, the oil immersion component includes an oil immersion sponge 1061 fixed to one side of the inside of the mounting groove 106 by screws, and the side of the oil immersion sponge 1061 extends to the inside of the oil storage tank 107. After the inside of the oil storage tank 107 is filled with lubricating oil, the inside of the oil immersion sponge 1061 can be soaked with lubricating oil to contaminate the surface of the lubricating ball 1063 with lubricating oil.

[0028] In order to facilitate the uniform oiling and lubrication treatment of the outer surface of the guide column 103 through the uniform rolling oiling assembly, in this embodiment, preferably, the uniform rolling oiling assembly includes a connecting plate 1062 arranged on one side of the oil-immersed sponge 1061 and located inside the mounting groove 106, and two lubricating balls 1063 are rolling at both ends of the interior of the connecting plate 1062, and the outer surface of the lubricating ball 1063 is embedded in the interior of the oil-immersed sponge 1061, so that the surface of the lubricating ball 1063 can be squeezed and contacted with the oil-immersed sponge 1061 for oil-immersed lubrication treatment when the guide column 103 is in the internal lubrication treatment of the lubrication cylinder 105.

[0029] In order to facilitate the elastic connection of the connecting plate 1062 through the elastic connecting component and to facilitate the smooth lubrication operation when squeezed during the lubrication process, in this embodiment, preferably, the elastic connecting component includes connecting grooves 1065 opened at both ends of the mounting groove 106, and a sliding rod 1067 is fixed inside the connecting groove 1065.

The two ends of the slider 1064 are located on the outer surface of the sliding rod 1067 and are provided with springs 1066. When the lubricating ball 1063 is squeezed, the spring 1066 is deformed to cause the slider 1064 to slide elastically on the outer surface of the sliding rod 1067, so that the lubricating ball 1063 is squeezed and the inner surface of the oil-immersed sponge 1061 is soaked with lubricating oil for lubrication.

[0030] The connecting mechanism includes a rotating connecting assembly arranged at the connection between the outer surface of the lubricating cylinder 105 and the top of the guide hole 104. A reinforcement assembly is provided at the top edge of the rotating connecting assembly. When the guide column 103 is lubricated by the lubricating cylinder 105, and the internal damage of the lubricating cylinder 105 is repaired due to long-term operation, the lubricating cylinder 105 can be disassembled and repaired by the connecting mechanism. The disassembly and maintenance are convenient, which improves the convenience of lubrication, disassembly, and maintenance of the mold lubrication structure main body 100 installed on the high-speed motor core mold.

[0031] In order to facilitate the rapid installation and lubrication of the lubrication cylinder 105 through the rotating connection assembly, and conversely facilitate rapid disassembly and maintenance when damaged, in this embodiment, preferably, the rotating connection assembly includes an internal threaded hole 1051 located at the top of the guide hole 104 inside the lower mold base 101, and the outer surface of the lubrication cylinder 105 is provided with an external thread structure 1056, and the external thread structure 1056 matches the internal structure of the internal threaded hole 1051. The top edge of the lubrication cylinder 105 is provided with an embedding groove 1057, which is convenient for engaging the tool in the internal embedding groove 1057 to rotate the lubrication cylinder 105. The external thread structure 1056 rotates the lubrication cylinder 105 to the inside of the internal threaded hole 1051 for fixed installation, which facilitates the disassembly and maintenance of the lubrication cylinder 105.

[0032] In order to facilitate the rotation and installation of the lubricating cylinder 105 inside the internal threaded hole 1051 through the reinforcement component and then strengthen the fixation again, in this embodiment, preferably, the reinforcement component includes a limiting groove 1053 opened at the top edge of the internal threaded hole 1051, and the internal limit of the limiting groove 1053 is provided with a reinforcing arc clamp 1052, and an elastic block 1054 is provided at the connection between the end of the reinforcing arc clamp 1052 and the inner surface of the limiting groove 1053. The reinforcing arc clamp 1052 is elastically connected to the inside of the limiting groove 1053 through the elastic block 1054, which is convenient for elastic snap-fit installation. An arc clamping hole 1055 is opened at the top edge of the lubricating cylinder 105, and the end of the reinforcing arc clamp 1052 is consistent with the internal structure of the arc clamping hole 1055 until the reinforcing arc clamp 1052 is elastically clamped to the inside of the arc clamping hole 1055 to strengthen the fixation after the lubricating cylinder 105 is rotated and installed.

[0033] The working principle and use process of the present invention are as follows: when using the high-speed motor core mold lubrication structure, the lubrication cylinder 105 is first fixed and installed, and the tool is engaged with the inside of the embedded groove 1057 to move the lubrication cylinder 105, and the lubrication cylinder 105 is rotated and fixed in the inside of the internal threaded hole 1051 through the external thread structure 1056 until the lubrication cylinder 105 is rotated and fixed to the bottom end of the internal threaded hole 1051 by the deformation of the elastic block 1054 to drive the reinforced arc clamping head 1052 to elastically engage with the inside of the arc clamping hole 1055 to strengthen the fixed installation after the lubrication cylinder 105 is rotated and installed. After the lubrication cylinder 105 is installed, the guide column 103 passes through the interior of the lubrication cylinder 105 for regular oiling and lubrication treatment. When the interior of the lubrication cylinder 105 is damaged and needs to be repaired, the opposite operation is performed to quickly disassemble and repair the lubrication cylinder 105, which is simpler and more convenient than disassembly and assembly with multiple bolts, thereby improving the convenience of disassembly and assembly of the mold lubrication structure main body 100 for lubrication treatment on the high-speed motor core mold;

[0034] Then, after the lubrication cylinder 105 is fixed and installed, the lubrication oil is filled into the oil storage tank 107 from the oil filling port. When the guide column 103 passes through the lubrication cylinder 105 for lubrication, after the oil sponge 1061 is immersed in oil, the guide column 103 is embedded in the lubrication cylinder 105, contacts the surface of the lubrication ball 1063 and squeezes it. During the squeezing, the spring 1066 is deformed to drive the slider 1064 to slide on the outer surface of the slide rod 1067, thereby driving the connecting plate 1062 to slide until the lubrication ball 1063 is squeezed. At the same time, the connecting plate 1062 is driven to move elastically inward so that the lubricating ball 1063 is squeezed into the oil-immersed sponge 1061 and immersed in oil, so that the lubricating ball 1063 contacts the outer surface of the guide column 103 for lubrication when rolling after the internal oil is immersed in oil, and the guide column 103 is evenly lubricated at the inner edge of the lubricating cylinder 105, and it is not easy to cause damage caused by direct squeezing of the sponge. The lubrication process is convenient, which improves the convenience and uniformity of the lubrication process when the mold lubrication structure main body 100 is installed on the high-speed motor core mold.

[0035] Although the embodiments of the present invention have been shown and described (see the detailed description above for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
