[0044] The following is combined with Figure 1-9 This application is described in further detail.

[0045] The present application embodiment discloses a plastic mold processing device. Figure 1 and Figure 2 As shown, the plastic mold processing equipment includes a bracket 1, a lifting base 2 and a support base 3 which are spaced apart from each other. The bottom of the support base 3 is connected to the bracket 1 through a plurality of vertically arranged first elastic telescopic rods 31. The first elastic telescopic rods 31 are used to support the support base 3, and the support base 3 is used to support the plastic mold to be processed.

[0046] A hydraulic cylinder 11 is mounted on the bracket 1, and a piston rod of the hydraulic cylinder 11 extends in a vertical direction and is connected to the lifting seat 2, on which a milling unit 4 is disposed. The hydraulic cylinder 11 is used to drive the lifting seat 2 to move up and down so that the milling unit 4 can mill the plastic mold on the support seat 3.

[0047] like Figure 2 and Figure 3 As shown, an inclined preparation plate 5 is installed on the bracket 1, and the lower end of the preparation plate 5 is located obliquely above the support seat 3. The plastic mold to be processed can be prepared in advance on the upper surface of the preparation plate 5; limit plates 51 are installed on the left and right sides of the preparation plate 5, and the two limit plates 51 are arranged at intervals, and the opposite sides of the two limit plates 51 and the upper surface of the preparation plate 5 together form a material guide cavity 52, and the material guide cavity 52 is used to limit the plastic mold, so that the plastic mold can only slide down along the upper surface of the preparation plate 5 to ensure that the plastic mold can accurately slide down to the upper surface of the support seat 3.

[0048] The bracket 1 is rotatably connected with a baffle plate 53 that can be turned over on a vertical plane. The baffle plate 53 is integrally formed with an extension plate 54. The extension plate 54 and the baffle plate 53 together form a "V"-shaped plate. The baffle plate 53 is connected to the bracket 1 through a torsion spring 55. When the torsion spring 55 is in a natural state, the extension plate 54 will be in a horizontal state. At this time, the baffle plate 53 will prevent the plastic mold in the material guide cavity 52 from sliding down, so that the plastic mold is blocked at a designated position in the material guide cavity 52.

[0049] When the hydraulic cylinder 11 drives the lifting seat 2 to descend, the lower surface of the lifting seat 2 will press down the extension plate 54 away from one end of the baffle 53. The extension plate 54 will drive the baffle 53 to rotate during the downward flipping process. The baffle 53 will first push the plastic mold up a short distance and then detach from the plastic mold. At this time, the baffle 53 has detached from the lower sliding track 14 of the plastic mold, that is, before the plastic mold is processed, the plastic mold for material preparation in the material guide cavity 52 will automatically slide down to the upper surface of the support seat 3; then the extension plate 54 will contact the side of the lifting seat 2 and gradually detach from the lifting seat 2, the torsion spring 55 will return to its natural state and prompt the extension plate 54 and the baffle 53 to flip and reset, so that the baffle 53 can block the subsequent plastic mold for material preparation.

[0050] It is worth noting that since the initial sliding position of the plastic mold is fixed, and the size and weight of the plastic molds in the same batch are the same, the position of each plastic mold on the upper surface of the support seat 3 after sliding down is also the same; therefore, by adjusting the inclination of the preparation plate 5, the plastic mold used for preparation can be automatically and accurately slid down to the processing position.

[0051] An inclined guide plate 32 is installed on one end of the support seat 3 away from the material preparation plate 5, and the high end of the guide plate 32 is connected to the support seat 3. When the plastic mold on the support seat 3 is processed, the subsequent prepared plastic mold will slide down to the processing position on the support seat 3 during the loading process, and push the processed plastic mold onto the guide plate 32, and the processed plastic mold will slide along the upper surface of the guide plate 32 to unload.

[0052] like Figure 1 and Figure 4 As shown, a driving motor 12 is provided on both sides of the support seat 3 . The driving motor 12 is installed on the bracket 1 . The output shaft of the driving motor 12 extends in the horizontal direction and is connected to a rotating frame 13 . The rotating frame 13 is provided with a clamping unit 6 .

[0053] like Figure 4 and Figure 5As shown, the clamping unit 6 includes two symmetrically arranged clamping seats 61, and the four clamping seats 61 are all arranged in an "L" shape; a limit rod 62 is slidably penetrated on the clamping seat 61, and the limit rod 62 is installed on the rotating frame 13, so that the clamping seat 61 can only slide along the axial direction of the output shaft of the driving motor 12.

[0054] A screw rod 63 is threadedly matched on the clamping seat 61, and the axial direction of the screw rod 63 is the same as the sliding direction of the clamping seat 61. The screw rod 63 is rotatable around its own axis and is connected to the rotating frame 13; the two screw rods 63 in the same group of clamping units 6 are connected by chain transmission, and a gear 64 is fixedly sleeved on one of the screw rods 63; two vertically arranged racks 21 are installed on the lower surface of the lifting seat 2, and the racks 21 correspond to the clamping units 6 one by one.

[0055] After the plastic mold is loaded onto the support seat 3, the hydraulic cylinder 11 will continue to drive the lifting seat 2 to descend, the lifting seat 2 will drive the rack 21 to descend, the rack 21 will drive the gear 64 to rotate, the gear 64 will drive the screw 63 to rotate, and the screw 63 will drive the clamping seat 61 to move toward the plastic mold, so that the four clamping seats 61 are clamped on the plastic mold together, realizing automatic clamping and fixation of the plastic mold.

[0056] A guide plate 65 is integrally formed on one end of the clamping seat 61 in the clamping unit 6 facing the other group of clamping units 6, and the distance between the two guide plates 65 in the clamping unit 6 gradually increases from the clamping unit 6 to the other group of clamping units 6. Therefore, even if there is a slight deviation between the position of the plastic mold on the support seat 3 and the processing position, the clamping seat 61 and the guide plate 65 can adjust the position of the plastic mold to ensure that the plastic mold can be accurately in the processing position.

[0057] like Figure 6 and Figure 7 As shown, two vertically arranged pressure columns 22 are installed on the lower surface of the lifting seat 2, and horizontally arranged card slots 33 are provided on the left and right sides of the support seat 3. Two horizontally arranged slide rails 14 are installed on the bracket 1, and the slide rails 14 are slidably matched with card columns 15. The card columns 15 are connected to the slide rails 14 through springs 16, and the card columns 15 are provided with a first guide surface 151 inclined upward.

[0058] When the clamping seat 61 is clamped on the plastic mold, the spring 16 will be in a natural state, and the clamping column 15 will be located outside the clamping slot 33. At this time, the clamping column 15 can be horizontally inserted into the clamping slot 33; in the process of the hydraulic cylinder 11 driving the lifting seat 2 to continue to descend, the lifting seat 2 will drive the pressure column 22 to press down the first guide surface 151, and the pressure column 22 will push the clamping column 15 to be inserted into the clamping slot 33 through the first guide surface 151. At this time, the support seat 3 will be limited and fixed at the current height to ensure the stability of the support seat 3 during the plastic mold processing process.

[0059] A second guide surface 152 inclined upward is provided on one end of the post 15 for inserting into the slot 33. During the process of inserting the post 15 into the slot 33, the post 15 can push the support seat 3 to rise through the second guide surface 152, so that the slot 33 is aligned with the post 15, so that the post 15 can be accurately inserted into the slot 33; therefore, even if the first elastic telescopic rod 31 is deformed after long-term use, so that the support seat 3 is slightly lower than its initial height, the post 15 can still cause the support seat 3 to rise to the initial height through the second guide surface 152, so as to ensure that the plastic mold is in the specified processing position during each processing process, thereby improving the processing accuracy of the plastic mold.

[0060] like Figure 4 As shown, an elastic pressing unit 7 is provided at the bottom of the lifting seat 2, and the elastic pressing unit 7 includes two pressing plates 71 respectively arranged at both sides of the plastic mold, and the pressing plates 71 are connected to the lower surface of the lifting seat 2 through two second elastic telescopic rods 72 arranged vertically. After the support seat 3 is fixed by plugging and plugging, the lifting seat 2 will cause the pressing plates 71 to press against the plastic mold during the process of continuing to descend, and the second elastic telescopic rods 72 will be compressed, so that the two pressing plates 71 jointly press the plastic mold against the support seat 3, thereby improving the stability of the plastic mold during the processing.

[0061] The milling unit 4 includes a three-dimensional linear module 41 installed on the lower surface of the lifting seat 2, and a rotary motor 42 is installed on the three-dimensional linear module 41. The output shaft of the rotary motor 42 is coaxially connected to a milling cutter 43 through a coupling. After the pressing plate 71 presses the plastic mold onto the support seat 3, the three-dimensional linear module 41 will drive the rotary motor 42 to move, and the rotary motor 42 will drive the milling cutter 43 to rotate, so that the milling cutter 43 mills the front of the plastic mold.

[0062] After the front milling of the plastic mold is completed, the hydraulic cylinder 11 will drive the lifting seat 2 to rise, so that the pressure plate 71 is separated from the plastic mold, and the pressure column 22 is separated from the clamping column 15, and the spring 16 will return to its natural state and cause the clamping column 15 to separate from the clamping slot 33; then the driving motor 12 will drive the rotating frame 13 to flip 180 degrees, and the rotating frame 13 will drive the clamping seat 61 and the guide plate 65 to rotate during the rotation process, the clamping seat 61 will drive the plastic mold to rotate, and the guide plate 65 will press down the support seat 3, so that the plastic mold can rotate 180 degrees normally, and the back of the plastic mold will face upwards.

[0063] Afterwards, the hydraulic cylinder 11 will drive the lifting seat 2 to descend, and the clamping column 15 will be reinserted into the clamping slot 33, so that the support seat 3 is plugged and fixed, and the pressing plate 71 will press the plastic mold against the support seat 3 again, and the milling cutter 43 will mill the reverse side of the plastic mold.

[0064] After the reverse milling of the plastic mold is completed, the hydraulic cylinder 11 will drive the lifting seat 2 to rise and reset, so that the pressure plate 71 is separated from the plastic mold, and the clamping column 15 is separated from the clamping groove 33, and the rack 21 drives the gear 64 to rotate. The gear 64 will drive the clamping seat 61 away from the plastic mold through the screw 63. At this time, the overall processing of the plastic mold has been completed.

[0065] like Figure 8 and Fig. 9 As shown, it is worth noting that a plurality of hemispherical receiving grooves 651 are provided at one end of the guide plate 65 away from the clamping seat 61, and balls 652 are rolled and embedded in the receiving grooves 651, and the balls 652 partially protrude from the receiving grooves 651. During the turning process of the rotating frame 13, the balls 652 will contact the support seat 3 instead of the guide plate 65, thereby converting the sliding friction between the guide plate 65 and the support seat 3 into the rolling friction between the balls 652 and the support seat 3, facilitating the turning of the rotating frame 13 and reducing the wear on the guide plate 65 and the support seat 3.

[0066] During the process of the lifting seat 2 ascending and resetting, the lifting seat 2 will contact the extension plate 54 again, causing the extension plate 54 to flip upward and gradually separate from the lifting seat 2, and then the torsion spring 55 will return to the natural state and cause the extension plate 54 and the baffle 53 to flip and reset.

[0067] like Figure 1 As shown, a controller 8 is installed on the bracket 1 , and the hydraulic cylinder 11 , the driving motor 12 , the three-dimensional linear module 41 and the rotary motor 42 are all coupled to the controller 8 .

[0068] The implementation principle of the plastic mold processing equipment of the embodiment of the present application is: during the processing of the plastic mold, the controller 8 will control the operation of the hydraulic cylinder 11 to make the lifting seat 2 descend to a specified height. During the descent process, the lifting seat 2 will first press down the extension plate 54, and the extension plate 54 will drive the baffle plate 53 to flip upward, so that the plastic mold in the guide cavity 52 slides down to the specified position on the support seat 3.

[0069] Then the lifting seat 2 will be separated from the extension plate 54, the torsion spring 55 will cause the extension plate 54 and the baffle 53 to rotate and reset, the lifting seat 2 will be engaged with the gear 64 through the rack 21, the gear 64 will drive the clamping seat 61 to move toward the plastic mold through the screw rod 63, and the guide plate 65 will fine-tune the position of the plastic mold so that the four clamping seats 61 are accurately clamped on the plastic mold.

[0070] Afterwards, the lifting seat 2 will drive the pressure column 22 to press down the first guide surface 151, and the pressure column 22 will push the clamping column 15 to move toward the support seat 3 through the first guide surface 151. The clamping column 15 will contact the support seat 3 through the second guide surface 152, so that the clamping column 15 can be accurately inserted into the clamping groove 33. At this time, the support seat 3 will be limited and fixed at a specified height.

[0071] Then the lifting seat 2 will cause the pressure plate 71 to press against the plastic mold, and the second elastic telescopic rod 72 will be compressed, so that the two pressure plates 71 will jointly press the plastic mold against the support seat 3. At this time, the lifting seat 2 has been lowered, and the controller 8 will control the three-dimensional linear module 41 and the rotary motor 42 to run according to the set PLC program, so that the milling cutter 43 automatically processes the front of the plastic mold.

[0072] After the front processing of the plastic mold is completed, the controller 8 will control the hydraulic cylinder 11 to operate so that the lifting seat 2 rises to a specified height. At this time, the pressure plate 71 will be detached from the plastic mold, the clamping column 15 will be detached from the clamping slot 33, and the clamping seat 61 is still clamped on the plastic mold; the controller 8 then controls the drive motor 12 to operate so that the rotating frame 13 drives the plastic mold to flip 180 degrees, so that the back of the plastic mold faces up, and the controller 8 will control the hydraulic cylinder 11 to operate so that the lifting seat 2 drops to a specified height. At this time, the clamping column 15 will re-insert and fix the support seat 3 at a specified height, and the pressure plate 71 will be re-pressed on the plastic mold. The controller 8 then controls the three-dimensional linear module 41 and the rotary motor 42 to operate according to the set PLC program, so that the milling cutter 43 processes the back of the plastic mold.

[0073] After the back side of the plastic mold is processed, the controller 8 will control the hydraulic cylinder 11 to operate so that the lifting seat 2 rises and resets. At this time, the pressing plate 71 will be separated from the plastic mold, the clamping column 15 will be separated from the clamping groove 33, the rack 21 will drive the gear 64 to rotate in the opposite direction, and the gear 64 will drive the clamping seat 61 to be separated from the plastic mold through the screw 63, so that the processed plastic mold can be pushed down by the subsequent plastic mold.

[0074] In summary, the present application realizes automatic loading, automatic clamping, automatic pressing, automatic flipping, automatic milling and automatic unloading of plastic molds, thereby improving the processing efficiency of plastic molds.

[0075] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
