Description

Technical Field

[0001] This utility model relates to the field of mold processing technology, and in particular to a rough processing equipment for stacked molds. Background Technology

[0002] As a core process equipment in modern manufacturing, the performance of laminated molds directly determines the forming accuracy and production efficiency of complex parts. In the automotive parts industry, laminated molds are used to manufacture key components such as engine blocks and gearbox housings. Their processing accuracy must be precise to ensure the airtightness of the engine and the stability of the transmission system. In the aerospace industry, laminated molds are used to process lightweight components such as aircraft skin and wing frames, which need to take into account both material strength and surface roughness requirements.

[0003] However, existing stacked mold roughing equipment has two major problems in the use of cutting fluid. First, the cutting fluid nozzle cannot monitor the temperature of the cutting area in real time. When the temperature is too high, it cannot automatically increase the flow rate to cool as needed, which affects the tool life. Second, the cutting waste fluid can only intercept large particles of impurities through the filter screen. The remaining fine metal chips and cutting oil cannot be effectively separated, which leads to the rapid deterioration of the cutting fluid and thus affects the machining accuracy. Utility Model Content

[0004] The main purpose of this utility model is to provide a roughing equipment for stacked molds, which aims to solve two major problems in the use of cutting fluid in existing roughing equipment for stacked molds. First, the cutting fluid nozzle cannot monitor the temperature of the cutting area in real time. When the temperature is too high, it cannot automatically increase the flow rate to cool as needed, which affects the tool life. Second, the cutting waste fluid can only intercept large particles of impurities through the filter screen. The remaining fine metal chips and cutting oil cannot be effectively separated, which leads to the rapid deterioration of the cutting fluid and thus affects the machining accuracy.

[0005] To achieve the above objectives, this utility model proposes a rough machining equipment for stacked molds, comprising a CNC machine housing, wherein a placement cavity and a machining cavity are respectively provided inside the CNC machine housing, a controller is provided on the front side of the CNC machine housing, a multi-axis linkage cutting tool is provided inside the machining cavity, a liquid tank is provided inside the placement cavity, a liquid spraying mechanism is provided on the right side of the multi-axis linkage cutting tool, a hollow frame is provided on the bottom side inside the machining cavity, and a filter collection assembly communicating with the liquid tank is provided at the bottom inside the placement cavity.

[0006] The liquid spraying mechanism includes a liquid pump located at the top of the liquid tank. The absorption end of the liquid pump is located inside the liquid tank, and the output end of the liquid pump is connected to a delivery pipe. A bracket is welded to the right side of the multi-axis linkage cutting tool. A nozzle and an infrared temperature sensor are installed inside the bracket, and the output and monitoring ends of both are facing the cutting area of ​​the multi-axis linkage cutting tool. The top of the nozzle is connected to the bottom of the delivery pipe.

[0008] Preferably, the purification structure includes a drain pipe connected to the bottom of the funnel, and a purification separation cylinder connected to the right side of the drain pipe. Inside the purification separation cylinder, a magnetic adsorption permanent magnet and a composite activated carbon filter are arranged sequentially along the downward direction of fluid flow.

The multi-axis linkage cutting tool performs rough machining, while the nozzle of the liquid spraying mechanism sprays and cools the cutting area. An infrared temperature sensor monitors the temperature in real time and feeds it back to the controller. The controller automatically adjusts the liquid pump flow rate and increases the nozzle spray flow rate, thereby extending the tool life. The cutting waste liquid falls into the filter collection assembly at the bottom of the placement cavity through the hollow frame.

[0028] This utility model provides a roughing equipment for stacked molds, which aims to solve two major problems in the use of cutting fluid in existing roughing equipment for stacked molds. First, the cutting fluid nozzle cannot monitor the temperature of the cutting area in real time. When the temperature is too high, it cannot automatically increase the flow rate to cool as needed, which affects the tool life. Second, the cutting waste fluid can only intercept large particles of impurities through the filter screen. The remaining fine metal chips and cutting oil cannot be effectively separated, which leads to the rapid deterioration of the cutting fluid and thus affects the machining accuracy.

[0029] like Figure 1-6 As shown in the figure, the present invention provides a rough machining equipment for a stacked mold, including a CNC machine housing 1. The CNC machine housing 1 has a placement cavity 2 and a machining cavity 3 respectively. A controller 4 is provided on the front side of the CNC machine housing 1. A multi-axis linkage cutting tool 5 is provided inside the machining cavity 3. A liquid tank 6 is provided inside the placement cavity 2. A liquid spraying mechanism 7 is provided on the right side of the multi-axis linkage cutting tool 5. A hollow frame 8 is provided on the bottom side inside the machining cavity 3. A filter collection assembly 9 communicating with the liquid tank 6 is provided at the bottom inside the placement cavity 2.

[0030] The liquid spraying mechanism 7 includes a liquid pump 701 located on the top of the liquid tank 6. The absorption end of the liquid pump 701 is located inside the liquid tank 6, and the output end of the liquid pump 701 is connected to a delivery pipe 702. A bracket 703 is welded to the right side of the multi-axis linkage cutting tool 5. A nozzle 704 and an infrared temperature sensor 705 are installed inside the bracket 703, and the output ends and monitoring ends of both are facing the cutting area of ​​the multi-axis linkage cutting tool 5. The top of the nozzle 704 is connected to the bottom of the delivery pipe 702.

[0031] In the technical solution of this utility model, by setting up a multi-axis linkage cutting tool 5, a liquid tank 6, a spraying mechanism 7, a hollow frame 8, and a filter collection assembly 9, the stacked mold workpiece is placed in the hollow frame 8 inside the processing cavity 3 and fixed. The multi-axis linkage cutting tool 5 performs rough cutting on the stacked mold using its own cutting tool. At the same time, the liquid pump 701 draws cutting fluid from the liquid tank 6 and sends it through the delivery pipe 702 to the nozzle 704 in the bracket 703. The output end of the nozzle 704 sprays and cools the cutting position of the multi-axis linkage cutting tool 5. During this process, the monitoring end of the infrared temperature sensor 705 monitors the temperature of the cutting area in real time. When the temperature exceeds the threshold, the controller 4 automatically instructs the liquid pump 701 to increase the delivery flow for precise cooling, thereby extending the multi-axis linkage cutting time. To extend the lifespan of the cutting tool 5 and improve surface finish, the cutting fluid and metal chips fall into the placement chamber 2 through the hollow frame 8. Large metal chips are filtered and intercepted by the bottom filter collection component 9, and then fine chips and cutting oil are separated and purified to reduce the impurity content of the waste fluid. The waste fluid is then returned to the liquid tank 6, thereby extending the cutting fluid circulation cycle and preventing the machining accuracy from being affected by the deterioration of the cutting fluid. The automatic linkage of temperature sensing and flow regulation combined with the waste fluid circulation system reduces manual intervention, shortens the time for rough machining of a single mold, and reduces the cost of cutting fluid consumption, which meets the requirements of green manufacturing. It should be noted that the multi-axis linkage cutting tool 5 consists of a multi-axis linkage drive device and a cutting tool. The multi-axis linkage drive device can drive the cutting tool to lift, move, and rotate to complete the cutting action.

[0032] Please refer to the following: Figure 4The filter collection assembly 9 includes an opening 901 on the bottom side of the machining cavity 3, a funnel 902 at the bottom of the opening 901, a receiving groove 903 on the front side of the machining cavity 3, a filter screen 904 inside the receiving groove 903, the filter screen 904 being located at the top of the funnel 902, and a purification structure 905 connected to the bottom of the funnel 902. The right side of the purification structure 905 is connected to the left side of the liquid tank 6. In this embodiment, by setting the filter collection assembly 9, the opening 901, the funnel 902, and the filter screen 904 in the receiving groove 903 on the bottom side of the machining cavity 3 form a primary filtration structure. After the cutting waste liquid falls into the machining cavity 3 through the hollow frame 8, it first passes through the filter screen 904 to intercept large particles such as iron filings and blocky debris. The filtered liquid then flows through the funnel 902 into the lower purification structure 905, where small metal particles and cutting oil are further filtered and purified before returning to the liquid tank 6. This reduces the subsequent purification load and improves the initial treatment efficiency of the waste liquid.

[0033] For further information, please continue to refer to [link / reference]. Figure 5 The purification structure 905 includes a drain pipe 9051 connected to the bottom of the funnel 902. The right side of the drain pipe 9051 is connected to a purification separation cylinder 9052. Inside the purification separation cylinder 9052, along the downward direction of fluid flow, a magnetic adsorption permanent magnet 9053 and a composite activated carbon filter 9054 are arranged sequentially. The magnetic adsorption permanent magnet 9053 is located in the middle inside the purification separation cylinder 9052, and the composite activated carbon filter 9054 is located at the bottom inside the purification separation cylinder 9052. The bottom of the purification separation cylinder 9052 is connected to a return pipe 9055, and the right side of the return pipe 9055 is connected to the left side of the liquid tank 6. In this embodiment, by setting up a purification structure 905, the filtered liquid enters the purification separation cylinder 9052 through the funnel 902 and the drain pipe 9051. The magnetic adsorption permanent magnet 9053 and the composite activated carbon filter 9054 in the purification separation cylinder 9052 form a dual purification process. First, magnetic adsorption: the magnetic adsorption permanent magnet 9053 adsorbs magnetic metal particles such as iron and nickel in the waste liquid through a magnetic field, reducing the impurity content of the liquid. Second, activated carbon filtration: the composite activated carbon filter 9054 adsorbs cutting oil and organic pollutants, realizing oil-liquid separation. This significantly reduces the impurity content of the purified cutting fluid, which can be directly returned to the liquid tank 6 through the return pipe 9055 for recycling, extending the service life of the cutting fluid and preventing deterioration from affecting machining accuracy.

[0034] Please continue to refer to this. Figure 4 A handle 10 is welded to the front side of the filter screen 904, and both sides of the front side of the handle 10 are arc-shaped. In this embodiment, by setting the handle 10, the arc-shaped handle 10 on the front side of the filter screen 904 makes it easy for operators to quickly pull out the filter screen 904 by hand, easily complete cleaning or replacement, avoid the impact of impurities on the waste liquid filtration efficiency, and improve the convenience of equipment maintenance.

[0035] Please refer to Figure 6 A liquid level sensor 11 is installed on the front side of the liquid tank 6. The sensing end of the liquid level sensor 11 is located inside the liquid tank 6, and the liquid level sensor 11 is electrically connected to the controller 4. In this embodiment, by setting the liquid level sensor 11, the cutting fluid level in the liquid tank 6 is monitored in real time. When the liquid level is lower than a preset threshold, an early warning signal is automatically sent to the controller 4 to prompt the operator to replenish the liquid in time, so as to avoid interruption of the cooling system or processing failure due to insufficient liquid, and ensure the continuous and stable operation of the equipment.

[0036] Additionally, please refer to Figure 6 A replenishment pipe 12 is connected to the top of the front side of the liquid tank 6, and an inlet 13 is connected to the top of the replenishment pipe 12. In this embodiment, by setting up the replenishment pipe 12 and the inlet 13, the replenishment pipe 12 connects the liquid tank 6 and the inlet 13, forming a convenient replenishment channel. The operator can directly add cutting fluid to the liquid tank 6 through the inlet 13 without disassembling the lid of the liquid tank 6. The funnel-shaped inlet 13 guides the liquid to flow in quickly, reducing spillage and waste, and significantly improving the replenishment efficiency.

[0037] Additionally, please refer to Figure 6 A plug 14 is fitted onto the top of the feed hopper 13, with the bottom of the plug 14 contacting the interior of the feed hopper 13. In this embodiment, by providing the plug 14, which is fitted onto the top of the feed hopper 13, dust and debris can be effectively prevented from falling into the liquid tank 6 and contaminating the cutting fluid. This avoids impurities from entering and causing tool wear or a decrease in machining accuracy. At the same time, sealing the opening of the feed hopper 13 reduces the evaporation of the cutting fluid and maintains the cleanliness of the inside of the liquid tank 6 and the stability of the liquid properties.

[0038] Additionally, please refer to Figure 6 A lifting rod 15 is fixedly connected to the top of the plug 14. The lifting rod is L-shaped. In this embodiment, by setting the lifting rod 15, the L-shaped lifting rod 15 design makes it easy for the operator to lift the plug 14 vertically with one hand. It is labor-saving and does not require contact with the surface of the plug 14, which not only improves the convenience of opening the feed hopper 13, but also keeps the operation hygienic and optimizes the human-machine interaction experience.
