Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically an automatic lubrication device for molds. Background Technology

[0002] Some CNC machine tools process workpieces using molds, and the lubrication effect of the molds significantly affects product quality, mold life, and production efficiency. Currently, mold lubrication mainly relies on manual operation, using a handheld oil gun or brush to apply lubricant to the mold surface. This method has the following problems: it is difficult to accurately control the amount and area of ​​lubricant applied, which can easily lead to insufficient or excessive lubrication in certain areas of the mold, affecting the surface finish of the product and the wear rate of the mold; manual lubrication requires the machine to be stopped, increasing production downtime, especially for large molds or complex mold sets, where a single lubrication takes a long time, seriously restricting the improvement of production efficiency; manual operation requires close contact with the high-temperature mold, which can easily cause burns and other safety accidents; at the same time, lubricant can easily come into contact with human skin, and long-term operation may affect the health of operators.

[0003] Therefore, an automatic lubrication device for molds is needed to replace manual lubrication of molds and solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art and provide an automatic mold lubrication device.

[0005] The specific solution of this utility model is as follows: an automatic mold lubrication device, including a lubricating oil reservoir, the lubricating oil reservoir having an oil drain port and an air inlet, the air inlet being connected to an air valve group via an air pipe, the air valve group being signal-connected to a machine tool control system, the air valve group being used to control the on / off of compressed air; the oil drain port being connected to the oil inlet of an oil injection switch via an oil pipe, the oil injection switch having a solenoid valve, the solenoid valve being used to control the on / off of the oil injection switch, the solenoid valve being signal-connected to a machine tool control system, the oil outlet of the oil injection switch being connected to an oil injection module, the oil injection module being used to inject oil into the mold, the oil injection module being connected to the mold drive mechanism of the machine tool.

[0006] Furthermore, the lubricating oil reservoir is equipped with an oil quantity adjustment knob, which is used to adjust the amount of oil discharged from the lubricating oil reservoir each time.

[0007] Furthermore, a pressure limiting valve is installed at the air inlet to limit the maximum air pressure entering the lubricating oil reservoir.

[0008] Furthermore, the oil injection module is equipped with a mold pressure head, an oil injection hole inside the mold pressure head, an oil injection pipeline inside the oil injection module, the oil injection pipeline being connected to the oil pipe, and the oil injection hole being connected to the oil injection pipeline.

[0009] Compared with existing technologies, this invention has the following advantages: 1. Significant time savings: Manual lubrication of molds requires workers to remove the mold from the equipment and disassemble it before adding lubricating oil. The automatic lubrication device can automatically add oil while the machine is running, saving considerable downtime and mold disassembly time, thus improving factory efficiency. 2. Reduced lubricating oil costs: The automatic lubrication device can adjust the amount of lubricating oil dispensed according to the mold's needs via a flow rate adjustment device. The oil dispensing time can be controlled via a machine tool signal-controlled oil dispensing switch, further saving lubricating oil used during mold lubrication. 3. Reduced risk of personal injury and property damage: Using this automatic mold lubrication device reduces direct contact between operators and lubricating oil, and also reduces the number of times operators need to install and disassemble the mold, thus reducing the incidence of personal injury accidents.

[0012] See Figure 1 This embodiment is an automatic mold lubrication device, including a lubricating oil reservoir 4. The lubricating oil reservoir 4 is provided with an oil drain port 41 and an air inlet 31. The air inlet 31 is connected to an air valve group 1 through an air pipe 2. The air valve group 1 is connected to the machine tool control system and is used to control the on / off of compressed air. The oil drain port 41 is connected to the oil inlet of an oil injection switch 7 through an oil pipe A6. The oil injection switch 7 is provided with a solenoid valve 71. The solenoid valve 71 is used to control the on / off of the oil injection switch 7 and is connected to the machine tool control system. The oil outlet of the oil injection switch 7 is connected to an oil injection module 8 through an oil pipe B9. The oil injection module 8 is used to inject oil into the mold and is connected to the mold drive mechanism of the machine tool.

[0013] Furthermore, the lubricating oil reservoir 4 is provided with an oil quantity adjustment knob 5, which is used to adjust the amount of oil discharged from the lubricating oil reservoir 4 each time.

[0014] Furthermore, a pressure limiting valve 3 is installed at the air inlet 31. The pressure limiting valve 3 is used to limit the maximum air pressure entering the lubricating oil reservoir 4. In this embodiment, the maximum air pressure is set to 40 PSI so that the air pressure entering the lubricating oil reservoir 4 will not be too high and will damage the lubricating oil reservoir.

[0015] Furthermore, the oil injection module 8 is provided with a mold pressure head, the mold pressure head is provided with an oil injection hole, the oil injection module 8 is provided with an oil injection pipeline, the oil injection pipeline is connected to the oil pipe, and the oil injection hole is connected to the oil injection pipeline.

[0016] Each time the air valve group 1 is opened, compressed air enters the lubricating oil reservoir 4, and the air pressure forces the lubricating oil out through the oil outlet 41 and into the oil injection switch 7 for temporary storage. When the solenoid valve 71 of the oil injection switch 7 is opened, the temporarily stored lubricating oil is then introduced into the oil injection module 8.

[0017] This embodiment is applied to a CNC turret punch press. The oil injection module 8 is connected to the punch. The center of the punch has an oil outlet hole. Whenever the punch moves and contacts the mold below, the machine tool control system will automatically send an oil injection signal. At this time, the control system opens the solenoid valve 71 to open the oil injection switch 7, and the lubricating oil will be automatically injected into the mold from the oil injection port of the punch.
