Description

Technical Field

[0001] This utility model relates to the field of automotive plastic mold technology, specifically to an adjustable precision milling device for automotive plastic molds. Background Technology

[0002] Automotive plastic molds are precision tools used to mold automotive plastic parts. Through molding processes such as injection molding, blow molding, and extrusion, plastic materials are processed into automotive parts with specific shapes and dimensions. They typically consist of a mold base, cavity, core, gating system, cooling system, and ejection mechanism. Precision milling of automotive plastic molds refers to the use of high-precision milling equipment (such as high-speed milling machines or CNC milling machines) to finely machine key parts of the mold during mold manufacturing to achieve the required dimensional accuracy and surface roughness. This machining method is usually performed after rough machining of the mold to remove excess material left from rough machining and ensure the final dimensional and shape accuracy of the mold.

[0003] Extensive research revealed problems with existing technologies for precision milling of automotive plastic molds. Since automotive plastic molds sometimes require fine machining, precision milling is necessary. However, this process involves rotating the milling cutter head, which generates debris and leaves plastic residue on the mold's inner wall, obstructing the operator's view and increasing the failure rate of precision milling. This hinders the successful precision milling of automotive plastic molds. Therefore, based on the aforementioned research and existing technologies, an adjustable precision milling device for automotive plastic molds is proposed to address these problems.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In one typical implementation of this application, please refer to Figures 1-5 An adjustable precision milling device for automotive plastic molds includes a base plate 1, a support frame 2 fixedly mounted on the top surface of the base plate 1, a fixed box 3 slidably connected to the top surface of the support frame 2, a support plate 4 for supporting the automotive plastic mold slidably connected to the top surface of the fixed box 3, a support frame 5 fixedly mounted on the top surface of the base plate 1, a servo motor 22 disposed on the top surface of the base plate 1, a precision milling head 23 for precision milling fixedly mounted on the bottom surface of the drive shaft of the servo motor 22, and a chip collection mechanism 6 disposed on the top surface of the support frame 5 for collecting chips generated during precision milling.

[0022] The debris collection mechanism 6 includes a support pipe 24, which is fixedly installed on the top surface of the support frame 5. The lower end of the support pipe 24 is tapered inward, and an air pump 26 is fixedly sleeved on the upper end of the support pipe 24. A connecting pipe 27 is fixedly sleeved on the inner circular wall of the outlet of the air pump 26. A collection box 28 is installed on the top surface of the support frame 5 through multiple columns. One end of the connecting pipe 27 passes through the connecting pipe 27 and extends into the interior of the collection box 28.

[0023] When the servo motor 22 drives the milling head 23 to mill the automotive plastic mold, debris will be generated in the automotive plastic mold. The air pump 26 starts to generate suction and sucks the debris in the automotive plastic mold into the collection box 28 through the support pipe 24 and the connecting pipe 27.

[0024] A cover plate 29 is rotatably connected to one side of the collection box 28 via a hinge. A connecting seat 30 is fixedly installed on the top surface of the collection box 28. An installation rod 32 is slidably connected inside the connecting seat 30. A support ring 31 is slidably connected to the outer circular wall of the installation rod 32. A spring 33 is sleeved on the outer circular wall of the installation rod 32. The spring 33 can provide force to the installation rod 32. One end of the spring 33 is fixedly connected to one end of the installation rod 32. The other end of the spring 33 is fixedly connected to one side of the support ring 31. A positioning frame 34 is fixedly installed at one end of the installation rod 32. A snap-fit ​​block 8 is fixedly installed on one side of the positioning frame 34. A snap-fit ​​groove 25 is opened on one side of the cover plate 29. The snap-fit ​​block 8 is movably snapped into the snap-fit ​​groove 25.

[0025] In this process, by moving the mounting rod 32 outward, the positioning frame 34 and the snap block 8 move outward, and at the same time, the spring 33 is compressed. The snap block 8 moves outward and separates from the snap groove 25. Then, by rotating the mounting rod 32 upward, the cover plate 29 can be opened and the debris in the collection box 28 can be taken out.

[0026] A PLC controller is fixedly mounted on the top surface of the substrate 1, and the servo motor 22 and the air pump 26 are both electrically connected to the PLC controller.

[0027] Preferably, through the set support plate 4, the worker places the car plastic mold on the top surface of the support plate 4, the PLC controller starts the servo motor 22, the drive shaft of the servo motor 22 rotates and drives the milling head 23 to rotate, and the milling head 23 rotates to perform milling on the car plastic mold;

[0028] During this process, the PLC controller starts the air pump 26. The air pump 26 generates suction to draw the debris generated by precision milling into the collection box 28 through the support pipe 24 and the connecting pipe 27 for storage. After precision milling is completed, the operator moves the mounting rod 32 outward. The mounting rod 32 moves outward inside the support ring 31, which drives the positioning frame 34 to move outward and compresses the spring 33. The outward movement of the positioning frame 34 drives the locking block 8 to move outward until it separates from the locking groove 25 on the cover plate 29. The operator rotates the mounting rod 32 outward, which drives the positioning frame 34 and the locking block 8 to rotate until the locking block 8 is rotated to a position outside the cover plate 29. At this time, the operator can open the cover plate 29 to take out the debris inside the collection box 28. This cleans up the debris generated during precision milling, avoids debris from affecting the field of vision and causing precision milling failure, and achieves the effect of debris collection for automotive plastic molds, which helps the operator to perform precision milling on plastic molds.

[0029] Inside the support frame 2, a lead screw 10 is rotatably connected via bearings. A drive motor 9 is mounted on one side of the support frame 2 to drive the lead screw 10 to rotate. One end of the drive shaft of the drive motor 9 passes through the support frame 2 and is fixedly connected to one end of the lead screw 10.

[0030] A mounting bracket 11 is threaded onto the outer cylindrical wall of lead screw 10. The top surface of mounting bracket 11 is fixedly connected to the bottom surface of fixed box 3. Driven by drive motor 9, lead screw 10 can rotate, thereby driving fixed box 3, bearing plate 4, and automotive plastic mold to move longitudinally via mounting bracket 11. Inside fixed box 3, lead screw 14 is rotatably connected via bearings. Drive motor 13 is installed on one side of fixed box 3 to drive lead screw 14. One end of drive shaft of drive motor 13 passes through fixed box 3 and is fixedly connected to one end of lead screw 14. A movable block 7 is threaded onto the outer cylindrical wall of lead screw 14. The top surface of movable block 7 is fixedly connected to the bottom surface of bearing plate 4. Driven by drive motor 13, lead screw 14 can rotate, thereby driving bearing plate 4 and automotive plastic mold to move laterally via movable block 7. Both drive motor 9 and drive motor 13 are electrically connected to PLC controller.

[0031] Preferably, the drive motor 9 drives the lead screw 10 to rotate, which in turn causes the mounting bracket 11 to move along the lead screw 10. The movement of the mounting bracket 11 causes the fixing box 3 to move, which in turn causes the support plate 4 and the automotive plastic mold to move longitudinally. This allows the automotive plastic mold to move longitudinally. The PLC controller then starts the drive motor 13, which drives the lead screw 14 to rotate. The rotation of the lead screw 14 causes the movable block 7 to move along the lead screw 14, which in turn causes the support plate 4 and the automotive plastic mold to move laterally. This facilitates the longitudinal and lateral movement of the automotive plastic mold during the precision milling process.

[0032] Several fixing blocks 16 are fixedly installed on the top surface of the support plate 4. A connecting frame 17 is rotatably connected between every two fixing blocks 16 via a rotating shaft. One side of the connecting frame 17 protrudes outward. A connecting frame 18 is rotatably connected to the upper end of the connecting frame 17 via a rotating shaft. Several support beams 19 are fixedly installed on both sides of the support plate 4. An electric push rod 20 for driving the connecting frame 18 to move is rotatably connected between every two support beams 19 via a rotating shaft. The telescopic shaft of the electric push rod 20 moves backward, causing the connecting frame 18 to move outward. The outward movement of the connecting frame 18 causes the connecting frame 17 to rotate outward. At this time, the automotive plastic mold is placed on the support plate 4. Subsequently, the multiple connecting frames 17 reset and fix the mold on the support plate 4. The electric push rod 20 is electrically connected to the PLC controller.

[0033] Preferably, the electric push rod 20 is set up so that its telescopic shaft moves inward, causing the connecting frame 18 to move outward. The outward movement of the connecting frame 18 causes the abutment frame 17 to rotate outward between the two fixed blocks 16. At this time, the worker places the car plastic mold on the top surface of the support plate 4. The telescopic shaft of the electric push rod 20 resets, causing the abutment frame 17 to reset. The protrusion of the abutment frame 17 will press against the top surface of the car plastic mold, thereby fixing the car plastic mold and preventing the car plastic mold from shifting during the precision milling process.

[0034] An electric push rod 21 for driving the servo motor 22 is fixedly installed on the inner bottom surface of the support frame 5. The bottom surface of the telescopic shaft of the electric push rod 21 is fixedly connected to the top surface of the servo motor 22. The electric push rod 21 is electrically connected to the PLC controller. The height of the servo motor 22 and the milling head 23 can be adjusted by the electric push rod 21.

[0035] Preferably, the electric push rod 21 is configured to move downwards, which in turn drives the servo motor 22 and the precision milling head 23 to move downwards, thereby adjusting the precision milling depth in the automotive plastic mold.

[0036] The support frame 2 has two limiting rods 12 fixedly installed inside. The mounting frame 11 is slidably connected to the limiting rods 12. The limiting rods 12 can restrict the movement of the mounting frame 11. The fixed box 3 has two limiting rods 25 fixedly installed inside. The movable block 7 is slidably connected to the limiting rods 25. The limiting rods 25 can restrict the movement of the movable block 7.

[0037] Preferably, the mounting bracket 11 moves along the limiting rod 12, which limits the movement of the mounting bracket 11. Correspondingly, the limiting rod 15 limits the movement of the lead screw 14, thus limiting the movement of the movable block 7.

[0038] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
