Detailed Embodiments

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be described clearly and completely below. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts also belong to the scope of protection of the present utility model.

[0027] As Figures 1-3 shown, the present utility model provides a mold processing device, which is characterized by comprising a workbench 1, a clamping mechanism 2, a mold processing box 3, and a recycling mechanism 4. The clamping mechanism 2 includes a control mechanism 20 located above the workbench 1 and a clamping plate 21 extending into the mold processing box 3. The mold processing box 3 includes a bracket 30 fixed on the workbench 1. A filter tank 31 is arranged above the bracket 30. A partition plate 32 is installed above the filter tank 31. A plurality of filter holes 33 are formed in the middle of the partition plate 32. An operation box 34 is installed above the filter holes 33. A cutting mechanism 340 is also arranged in the operation box 34. The recycling mechanism 4 includes a coarse filter box 40 communicated with the filter tank 31. A coarse filter plate 41, a fine filter box 42, a fine filter plate 43, and a suction filter box 44 are sequentially arranged below the coarse filter box 40. The coarse filter box 40 and the fine filter box 42 are both communicated with a filter residue box 45. The recycling mechanism 4 further includes a material pushing mechanism 46.

[0028] When the mold processing device is working, the workbench 1 is used to fixedly support the whole device. The clamping mechanism 2 is used to clamp and fix the mold placed in the mold processing box 3 to prevent it from shifting during the processing. The mold processing box 3 is used to perform specific processing operations on the mold. The recycling mechanism 4 is used to recycle the waste materials (including cutting fluid and mold scraps) generated during the mold processing.

[0029] The specific process is as follows: The mold to be processed is placed in the operation box 34, and the mold to be processed is processed by the cutting mechanism 340. The waste materials generated during the processing fall on the partition plate 32 at the bottom of the operation box 34. Among them, the relatively large mold scraps are blocked by the partition plate 32 and stay in the operation box 34. After the processing is completed, the mold scraps can be pushed out of the operation box 34 by the material pushing mechanism 46 for collection. The relatively small mold scraps and cutting fluid flow down through the filter holes 33 and fall into the filter tank 31. The mold scraps and cutting fluid in the filter tank 31 flow into the coarse filter box 40. After being filtered by the coarse filter plate 41 at the bottom of the coarse filter box 40 to remove a part of the mold scraps, they flow into the fine filter box 42. After being secondarily filtered by the fine filter plate 43 at the bottom of the fine filter box 42, the clean cutting fluid enters the suction filter box 44 and can be recycled. The mold scraps filtered by the coarse filter plate 41 and the fine filter plate 43 and staying in the coarse filter box 40 and the fine filter box 42 enter the filter residue box 45, and the mold scraps in the filter residue box 45 are recycled regularly.

[0030] The mold processing device provided by the utility model realizes the separation of cutting waste liquid and mold waste chips generated during the mold processing process through the synergistic effect of the mold processing box 3 and the recycling mechanism 4, and separately recycles the separated cutting fluid and mold waste chips. The whole process does not require manual collection of waste materials, reducing the labor intensity of workers, also reducing the difficulty of collecting waste materials, improving the efficiency of resource recycling and utilization, and reducing production costs.

[0031] As Figure 3 and Figure 4 shown, further, a slope 35 is installed in the filter tank 31. The end of the slope 35 close to the coarse filter box 40 is the bottom end, and the end far from the coarse filter box 40 is the high end. Further, a first air cylinder 401 is installed outside the side wall of the coarse filter box 40 away from the filter residue box 45. The output end of the first air cylinder 401 penetrates the side wall of the coarse filter box 40 and is connected to a first push plate 402. A liquid baffle 403 is also installed between the coarse filter box 40 and the filter residue box 45, and the liquid baffle 403 is hinged to the coarse filter box 40. Further, the coarse filter box 40 and the fine filter box 42 have exactly the same structure except for the aperture of the holes opened on the coarse filter plate 41 and the fine filter plate 43. The aperture of the filter holes 33, the apertures of the holes opened on the coarse filter plate 41 and the fine filter plate 43 decrease in sequence. Further, the suction filtration box 44 is provided with a suction filtration hole 440 and a liquid discharge hole 441. Further, the pushing mechanism 46 includes a plurality of second air cylinders 460 located outside the operation box 34. The output ends of the second air cylinders 460 penetrate the side wall of the operation box 34 and are connected to a second push plate 461.

[0032] During the mold processing process, the cutting waste liquid and mold waste chips generated will fall on the slope 35 after entering the filter tank 31. Under the action of gravity, the cutting waste liquid and mold waste chips flow into the coarse filter box 40 along the slope 35 and are filtered twice through the coarse filter box 40 and the fine filter box 42. When filtering the mold waste chips in the cutting waste liquid, multiple filtrations are carried out through the filter holes 33 opened on the partition plate 32, the coarse filter plate 41 and the fine filter plate 43. On the one hand, it can improve the filtering effect of the cutting waste liquid, and on the other hand, it can avoid the phenomenon of filter plate blockage caused by filtering too many mold waste chips at one time.

[0033] During filtration, the suction filtration box 44 (fine filter plate 43) is below the suction filtration box 44. The suction filtration box 44 is provided with a suction filtration hole 440, and the suction filtration hole 440 can be connected to a negative pressure device (not shown in the figure) to improve the filtration rate. The suction filtration box 44 is also provided with a liquid discharge hole 441 for the secondary utilization of the filtered cutting fluid.

[0034] After the filtration is completed, the mold waste chips remaining in the operation box 34 are pushed out by the pushing mechanism 46 and then collected. When the pushing mechanism 46 is working, a plurality of second cylinders 460 outside the operation box 34 drive the second pushing plate 461 located inside the operation box 34, and the mold waste chips can be pushed out.

[0035] The rough filter box 40 and the fine filter box 42 have exactly the same structure except for the aperture diameters of the openings on the rough filter plate 41 and the fine filter plate 43. Here, taking the rough filter box 40 as an example, the process of discharging the mold waste chips to the filter residue box 45 is described as follows: During the filtration process, the liquid baffle 403 is in a closed state. At this time, the rough filter box 40 and the filter residue box 45 are in a separated state. Under the separation of the liquid baffle 403, the cutting fluid will not enter the filter residue box 45. When the filtration is completed, the first cylinder 401 drives the first pushing plate 402 to push the mold waste chips remaining in the rough filter box 40. Since the liquid baffle 403 is hinged to the rough filter box 40, when the first pushing plate 402 pushes the mold waste chips to the liquid baffle 403, the liquid baffle 403 will be lifted, and the mold waste chips will fall into the filter residue box 45 for storage. The bottom of the filter residue box 45 is provided with a discharge port (not shown in the figure), and the mold waste chips therein can be processed regularly.

[0036] As shown in Figure 5, further, the control mechanism 20 includes a fixed seat 201 on the workbench 1, and a shuttle-shaped plate 202 is installed on the fixed seat 201. Both ends of the shuttle-shaped plate 202 are provided with first connecting shafts 203, and a connecting rod 204 is installed on each first connecting shaft 203. The other end of the connecting rod 204 is connected with a second connecting shaft 205, and a movable plate 206 is also installed on each second connecting shaft 205. A chute 207 is installed below each movable plate 206, and a slide rail 208 is installed in cooperation with the lower part of the chute 207. A vertical plate 209 is installed above each movable plate 206, and a cross plate 211 is connected above the vertical plate 209. The cross plate penetrates the side wall of the operation box 34 and is connected with the clamping plate 21. A connecting block 210 is also installed below the end of one movable plate 206, and the connecting block 210 is connected with the output end of the third cylinder 213. Further, limit blocks 212 are installed at both ends of each chute 207.

[0037] When the control mechanism 20 is in use, a connecting block 210 is driven by a third cylinder 213 to move, and this connecting block 210 drives the upper movable plate 206 to move. The movable plate 206 drives the sliding groove 207 to move on the sliding rail 208. At the same time, the connecting rod 204 also moves under the action of the second connecting shaft 205. The connecting rod 204 drives the first connecting shaft 203 at the other end and the shuttle-shaped plate 202 below it to move. The shuttle-shaped plate 202 is rotatably connected to the fixed seat 201. Therefore, the moving shuttle-shaped plate 202 will drive the movable plate 206, the sliding groove 207 and other components on the other side without being driven by the third cylinder 213 to move. The movable plate 206 drives the vertical plate 209 and the horizontal plate 211 to move, and the horizontal plate 211 pushes the clamping plate 21 to clamp the mold workpiece. And the clamping plates 21 on both sides of the operation box 34 generate displacements synchronously, so that mold workpieces of any size will be fixed in the middle of the operation box 34.

[0038] As Figure 1 and Figure 4 shown, further, the cutting mechanism 340 includes a cutting piece 341 and a cutting fluid pipe 342. Both the cutting piece 341 and the cutting fluid pipe 342 penetrate through the top of the operation box 34. An activity door panel 36 is also installed on the operation box 34.

[0039] The cutting piece 341 is used for cutting and processing the mold assembly, and the cutting fluid pipe 342 is used for spraying cutting fluid to assist cutting during the cutting process. At the same time, in addition to being connected to the cutting fluid tank, the cutting fluid pipe 342 can also be connected to the drain hole 441 on the suction filtration box 44.

[0040] An activity door panel 36 is also installed on the operation box 34. When performing mold processing, the activity door panel 36 is closed to prevent the splashing of cutting waste liquid and mold chips. The side wall of the operation box 34, the activity door panel 36 and the activity door panel are made of transparent materials for easy observation of the processing process.

[0041] The complete operation process of the mold processing device provided by the present utility model is as follows: Open the activity door panel 36, put the mold to be processed into the operation box 34, and close the activity door panel 36. Fix the mold to be processed in the middle of the operation box 34 through the clamping mechanism 2. The clamping process is as follows: The third cylinder 213 drives a connecting block 210 to move, and this connecting block 210 drives the upper movable plate 206 to move. The movable plate 206 drives the sliding groove 207 to move on the sliding rail 208. At the same time, the connecting rod 204 also moves under the action of the second connecting shaft 205. The connecting rod 204 drives the first connecting shaft 203 at the other end and the shuttle-shaped plate 202 below it to move. The shuttle-shaped plate 202 will drive the movable plate 206, the sliding groove 207 and other components on the other side without being driven by the third cylinder 213 to move. The movable plate 206 drives the vertical plate 209 and the horizontal plate 211 to move, and the horizontal plate 211 pushes the clamping plate 21 to clamp the mold workpiece.

[0042] After the mold workpiece is fixed, the cutting fluid pipe 342 sprays out cutting fluid, and at the same time, the cutting piece 341 starts to process the mold workpiece.

[0043] The waste generated during the processing falls on the partition plate 32 at the bottom of the operation box 34. Among them, the larger mold scraps are blocked by the partition plate 32 and stay in the operation box 34. After the processing is completed, the mold scraps can be pushed out of the operation box 34 by the pushing mechanism 46 for collection. The smaller mold scraps and cutting fluid flow down through the filter holes 33 and fall into the filter tank 31. In the filter tank 31, they flow into the coarse filter box 40 from the slope 35. After filtering out part of the mold scraps by the coarse filter plate 41 at the bottom of the coarse filter box 40, they flow into the fine filter box 42. After being secondarily filtered by the fine filter plate 43 at the bottom of the fine filter box 42, the clean cutting fluid enters the suction filter box 44 and can be recycled. During filtration, a negative pressure device is connected to the suction filter hole 440 on the suction filter box 44 to improve the filtration rate.

[0044] After the processing is completed, the mold is taken out, and the pushing mechanism 46 is started to push out and collect the mold scraps in the operation box 34. The mold scraps in the coarse filter box 40 can be recycled during the processing: during the filtration process, the liquid baffle 403 is in a closed state. At this time, the coarse filter box 40 and the filter residue box 45 are in a separated state. Under the separation of the liquid baffle 403, the cutting fluid will not enter the filter residue box 45. When the filtration is over, the first air cylinder 401 drives the first pushing plate 402 to push the mold scraps remaining in the coarse filter box 40. Since the liquid baffle 403 is hinged to the coarse filter box 40, when the first pushing plate 402 pushes the mold scraps to the liquid baffle 403, the liquid baffle 403 will be lifted, and the mold scraps will fall into the filter residue box 45 for storage. An outlet (not shown in the figure) is provided at the bottom of the filter residue box 45, and the mold scraps in it can be processed regularly. The working process of the fine filter box 42 is the same as that of the coarse filter box 40.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
