Description
Technical Field
[0001] This application belongs to the technical field of injection mold production, and specifically relates to an injection mold production and processing device. Background Art
[0002] During the production and processing of injection molds, milling cutters are usually used. Milling cutters play an important role in the manufacturing of injection molds. For example, when machining the cavity and core surfaces of the mold, as well as various structural features, milling cutters can perform operations such as face milling, contour milling, and cavity milling to achieve the required shape and dimensional accuracy. In the rough machining stage of the mold, a milling cutter with a larger diameter may be used to quickly remove excess material; while in the finishing stage, a milling cutter with a smaller diameter and high precision is selected to obtain a finer surface quality and dimensional accuracy. In short, milling cutters are one of the indispensable tools in the production and processing of injection molds.
[0003] In the prior art, during the production and processing of injection molds, due to the intricate internal structure of the mold cavity, a large amount of debris accumulates during the grinding of the milling cutter. In addition, grinding fluid is usually used for lubrication and flushing during the grinding of the milling cutter, which causes the debris and grinding fluid to cover, accumulate, and block the grinding position to a certain extent. If not removed in time, it will affect the accuracy and effect of the grinding part. In addition, if the grinding fluid mixed with waste chips is not separated and reused, it will increase the processing cost. Therefore, in order to solve this problem, it is necessary to optimize the design of this product, and it is necessary to propose an injection mold production and processing device. Summary of the Utility Model
[0004] The purpose of this application is to provide an injection mold production and processing device to solve the above-mentioned problems.
[0005] The technical solution adopted in this application is as follows: An injection mold production and processing device includes a bottom plate. On the right side of the top of the bottom plate, a waste table is fixedly installed. On the left side of the waste table, a milling cutter assembly is fixedly installed. Above the right side of the milling cutter assembly, a top plate is fixedly installed. On the top of the top plate, a gripper is fixedly installed. On both inner sides of the top plate and the gripper, clamping plates are slidably installed respectively. Below the right side of the milling cutter assembly, there is a milling cutter and a flushing pipe located below the top plate.
[0006] Three chute are respectively opened inside the top of the waste table. A pair of scrapers are slidably installed at the rear side inside the top of the waste table. The pair of scrapers are respectively located at the positions spaced apart by the three chute. A recovery box is fixedly installed at the top of the bottom plate. A liquid tank and a waste chip tank are respectively opened at the top of the recovery box. A support is fixedly installed at the left side of the top of the recovery box. A filter cylinder is rotatably connected to the top of the support through a bearing. The filter cylinder is provided with closely arranged filter holes. A gear ring is fixedly installed on the left side of the outer wall of the filter cylinder. A gear disk is engaged with the bottom of the gear ring. The rotational power source of the gear disk is a drive motor fixedly installed at the right end of the support. A liquid pump is fixedly installed at the left side of the recovery box. Two ends of the liquid pump are respectively communicated with the liquid tank and a flushing pipe through pipelines.
[0007] In a preferred embodiment, chutes adapted to the clamping plates are respectively opened on both inner sides of the top plate and the clamp. And the clamping plates are slidably installed in the chutes.
[0008] In a preferred embodiment, screw rods with opposite external threads are respectively rotatably installed on both inner sides of the clamp. The screw rods are threadedly connected to the top of the clamping plates. A first double-headed motor with two output ends respectively fixed to the two screw rods is fixedly installed in the middle of the clamp.
[0009] In a preferred embodiment, moving grooves adapted to the two scrapers are respectively opened at the rear side inside the top of the waste table. The scrapers are slidably installed in the moving grooves.
[0010] In a preferred embodiment, threaded rods with opposite external threads are respectively threadedly connected to the rear ends of the two scrapers. A second double-headed motor with two output ends respectively fixed to the two threaded rods is fixedly installed in the middle of the rear side inside the top of the waste table.
[0011] In a preferred embodiment, the filter cylinder is designed with a structure that slopes downward at the right end. The right end of the filter cylinder is located above the waste chip tank. The filter holes opened on the filter cylinder are located above the liquid tank.
[0012] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present application are:
[0013] 1. In this application, through the above design, when using this device to process an injection mold, first place the metal sheet for making the mold between two clamping plates. Then start the first double-headed motor to drive two lead screws to rotate, so as to drive the two clamping plates to approach each other through screw extrusion to fix the metal processing sheet. Then start the milling cutter on the right side of the milling cutter assembly to process the metal sheet from the bottom, and at the same time use the flushing pipe to spray grinding fluid for flushing and lubrication. Since the milling cutter processes the metal sheet in an inverted manner, the grinding fluid will wash the waste chips cut during processing and directly fall from the bottom of the metal sheet, rather than accumulating at the processing site, thus avoiding the impact of waste chips and grinding fluid on the processing site. When the grinding fluid mixed with the waste chips from processing and cutting drops, it will directly fall on the top of the waste material table. At this time, start the second double-headed motor to drive two threaded rods to rotate, so that the two scrapers continuously approach and move away from each other. At this time, the scrapers will push the waste chips and grinding fluid dropped on the top of the waste material table to both sides, making them fall into the inclined chute drain plate through the drop slot, and finally be discharged into the left end interior of the inclined filter cylinder through the drain pipe. When the waste chips and grinding fluid come into the filter cylinder, start the drive motor to drive the gear disk to engage and rotate the gear ring, so that the gear ring drives the filter cylinder to rotate. At this time, the grinding fluid will be discharged into the liquid tank through the filter holes for collection, while the waste chips will continuously roll and be discharged into the waste chip slot from the right end of the filter cylinder for separation and recycling. Since a liquid pump is provided on the left side of the recycling box and is connected to the liquid tank and the flushing pipe respectively through pipelines, the liquid pump can re-discharge the grinding fluid recovered in the liquid tank onto the flushing pipe for spraying, thereby realizing the recycling of the grinding fluid to enhance the practicality of this device.

Detailed Embodiments
[0018] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0019] Referring to Figure 1 and 2 , an injection mold production and processing device includes a bottom plate 1. On the right side of the top of the bottom plate 1, a waste table 2 is fixedly installed. On the left side of the waste table 2, a milling cutter assembly 3 is fixedly installed. Above the right side of the milling cutter assembly 3, a top plate 4 is fixedly installed. On the top of the top plate 4, a gripper 5 is fixedly installed. On both inner sides of the top plate 4 and the gripper 5, clamping plates 6 are slidably installed respectively. On both inner sides of the top plate 4 and the gripper 5, chutes adapted to the clamping plates 6 are provided, and the clamping plates 6 are slidably installed in the chutes. On both inner sides of the gripper 5, lead screws 7 with opposite external threads are rotatably installed respectively. The lead screws 7 are threadedly connected to the top of the clamping plates 6. In the middle of the gripper 5, a first double-headed motor 8 with two output ends respectively fixed to the two lead screws 7 is fixedly installed. Below the right side of the milling cutter assembly 3, there are a milling cutter 9 and a flushing pipe 10 located below the top plate 4.
[0020] With the above design, when using this device to process an injection mold, first place the metal plate for making the mold between the two clamping plates 6, then start the first double-headed motor 8 to drive the two lead screws 7 to rotate, so as to drive the two clamping plates 6 to approach each other by screw extrusion to fix the metal processing plate. Then start the milling cutter 9 on the right side of the milling cutter assembly 3 to process the metal plate from the bottom, and at the same time use the flushing pipe 10 to spray the grinding fluid for flushing and lubrication. Since the milling cutter 9 processes the metal plate in an inverted manner, the grinding fluid will wash the waste chips cut during processing and directly fall from the bottom of the metal plate, and will not accumulate at the processing site, thus avoiding the influence of waste chips and grinding fluid on the processing site.
[0021] Referring to Figure 1 and 2, 3, three dropping grooves 11 are respectively formed in the top inside of the waste table 2. A pair of scraping plates 12 are slidably installed at the rear side inside the top of the waste table 2. The pair of scraping plates 12 are respectively located at the positions alternating with the three dropping grooves 11. Moving grooves adapted to the two scraping plates 12 are respectively formed at the rear side inside the top of the waste table 2. The scraping plates 12 are slidably installed in the moving grooves. The rear ends of the two scraping plates 12 are respectively threadedly connected with threaded rods 13 with opposite external thread settings. A second double-headed motor 14 with two output ends respectively fixed to the two threaded rods 13 is fixedly installed in the middle at the rear side inside the top of the waste table 2. A recycling box 16 is fixedly installed on the top of the bottom plate 1. A liquid tank 17 and a waste chip tank 18 are respectively formed at the top of the recycling box 16. A support 19 is fixedly installed on the left side at the top of the recycling box 16. The top of the support 19 is rotatably connected with a filter cylinder 20 through a bearing. Filter holes 21 are densely arranged on the filter cylinder 20. The filter cylinder 20 is designed with a structure that slopes downward at the right end. The right end of the filter cylinder 20 is located above the waste chip tank 18. The filter holes 21 formed on the filter cylinder 20 are located above the liquid tank 17. A gear ring 22 is fixedly installed on the left side of the outer wall of the filter cylinder 20. A gear disk 23 is engaged with the bottom of the gear ring 22. The rotational power source of the gear disk 23 is a driving motor fixedly installed at the right end of the support 19. A liquid pump 24 is fixedly installed on the left side of the recycling box 16. The two ends of the liquid pump 24 are respectively communicated with the liquid tank 17 and the flushing pipe 10 through pipelines.
[0022] Through the above design, when the grinding liquid mixed with the waste chips from processing and cutting drops, it will directly fall on the top of the waste table 2. At this time, start the second double-headed motor 14 to drive the two threaded rods 13 to rotate, so that the two scraping plates 12 continuously move closer to and away from each other. At this time, the scraping plates 12 will push the waste chips and grinding liquid dropped on the top of the waste table 2 to both sides, making them fall into the inclined chute deflector 15 from the dropping grooves 11 and finally discharged into the left end inside of the inclined filter cylinder 20 through the diversion pipe 25. When the waste chips and grinding liquid come inside the filter cylinder 20, start the driving motor to drive the gear disk 23 to engage and rotate the gear ring 22, so that the gear ring 22 drives the filter cylinder 20 to rotate. At this time, the grinding liquid will be discharged into the liquid tank 17 through the filter holes 21 for receiving, while the waste chips will continuously roll and be discharged into the waste chip tank 18 from the right end of the filter cylinder 20 for separation and recycling. Since a liquid pump 24 respectively communicated with the liquid tank 17 and the flushing pipe 10 through pipelines is arranged on the left side of the recycling box 16, the liquid pump 24 can discharge the grinding liquid recovered in the liquid tank 17 into the flushing pipe 10 to be sprayed out again, so as to realize the recycling of the grinding liquid and enhance the practicability of the device.
[0023] The implementation principle of the embodiment of this application is:
[0024] First, when using this device to process an injection mold, place the metal sheet used to make the mold between the two clamping plates 6. Then start the first double-headed motor 8 to drive the two lead screws 7 to rotate, so as to drive the two clamping plates 6 to approach each other through thread extrusion to fix the metal processing sheet. Then start the milling cutter 9 on the right side of the milling cutter assembly 3 to process the metal sheet from the bottom, and at the same time use the flushing pipe 10 to spray grinding fluid for flushing and lubrication. Since the milling cutter 9 processes the metal sheet in an inverted manner, the grinding fluid will flush the waste chips cut during processing and directly fall from the bottom of the metal sheet, rather than accumulating at the processing site, thus avoiding the influence of waste chips and grinding fluid on the processing site.
[0025] When the grinding fluid mixed with the waste chips from processing and cutting falls, it will directly land on the top of the waste material table 2. At this time, start the second double-headed motor 14 to drive the two threaded rods 13 to rotate, so that the two scraping plates 12 continuously approach and move away from each other. At this time, the scraping plates 12 will push the waste chips and grinding fluid falling on the top of the waste material table 2 to both sides, making them fall into the inclined chute drainage plate 15 through the falling groove 11, and finally drain into the left end interior of the inclined filter cylinder 20 through the drainage pipe 25. When the waste chips and grinding fluid enter the filter cylinder 20, start the drive motor to drive the gear disk 23 to engage the gear ring 22 to rotate, so that the gear ring 22 drives the filter cylinder 20 to rotate. At this time, the grinding fluid will be discharged into the liquid tank 17 through the filter holes 21 for receiving, while the waste chips will continuously roll and be discharged into the waste chip groove 18 from the right end of the filter cylinder 20 for separation and recovery. Since a liquid pump 24 is provided on the left side of the recovery box 16 and is connected to the liquid tank 17 and the flushing pipe 10 through pipes respectively, the liquid pump 24 can discharge the grinding fluid recovered in the liquid tank 17 back into the flushing pipe 10 and spray it out, thus realizing the recycling of the grinding fluid to enhance the practicality of this device.
[0026] The above is only a preferred embodiment of the present application and is not intended to limit the present application.
