Description

Technical Field

[0001] The invention relates to the technical field of injection mold guide column processing, in particular to a surface treatment device for processing an automobile lampshade injection mold. Background Art

[0002] Injection molding is a method for producing industrial products. Products are typically produced using rubber and plastic injection molding. Injection molding can also be categorized into compression molding and die casting. Injection molding machines are the primary molding equipment used to create various shapes of plastic products from thermoplastics or thermosets using plastic molding molds. Commonly used automotive headlights are molded using injection molding machines and molds, enabling the production of various sizes and shapes. The injection mold is a core component in the injection molding process. To ensure accurate closing and alignment, guide pins are required to provide support and improve alignment accuracy. When machining the guide pins of injection molds, the outer walls of the guide pins are ground and polished using surface treatment equipment to ensure surface smoothness.

[0003] When the surface treatment device in the prior art is grinding the surface of the guide post, it generally adopts manual support to support one end of the guide post and inserts the other end of the guide post into the device for grinding. This method can easily cause harm to the workers and cannot guarantee the personal safety of the workers. If a clamp is used to clamp and fix the two ends of the guide post, and the outer wall of the guide post is ground with the help of a movable grinding wheel, the parts of the guide post clamped by the clamp cannot be ground by the grinding wheel, thereby resulting in the generation of dead angles in the grinding of the guide post surface, affecting the effect of the device on the grinding treatment of the guide post surface, making the device unable to meet people's usage needs. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to provide a surface treatment device for processing an automobile lampshade injection mold.

[0008] Optionally, guide grooves are provided on both side outer walls of the loading box near the discharge outlet, and moving blocks are slidably installed inside the two guide grooves. The first driving screw rod and the sliding rod are respectively installed on both side outer walls of the loading box, and the two moving blocks are respectively matched with the outer walls of the first driving screw rod and the sliding rod, and the close ends of the two moving blocks are commonly connected to a push plate.

[0011] Optionally, a third electric telescopic rod is installed on the outer wall of the two second sliding blocks away from the second sliding groove, and a mounting seat is installed on the telescopic ends of the two third electric telescopic rods, and a grinding wheel is installed inside the two mounting seats.

[0012] Optionally, the clamping mechanism includes two second drive screws rotatably mounted inside the second fixed frame, the outer walls of the two second drive screws are each installed with a second movable seat, and the top of the two second movable seats is each installed with a mounting plate through two bolt threads, and two first electric push rods are installed on the top of the two mounting plates.

[0013] Optionally, the telescopic ends of the two first electric push rods are both equipped with clamping blocks, the outer walls on both sides of the two clamping blocks are both equipped with fixing rods, and the outer walls on the sides where the two fixing rods are close to each other are connected to auxiliary splints through the second electric push rod.

[0015] Optionally, two polishing rods are installed on the outer walls of the adjacent sides of the two clamping blocks, and the two polishing rods are in contact with the outer wall of the guide column when in use.

[0016] The beneficial effects of the present invention are:

[0017] 1. In this invention, after the two grinding wheels have finished grinding the surface of the guide post, the two clamping blocks are controlled to drive the two grinding blocks close to the outer wall of one side to slightly contact the two ends of the guide post, and the corresponding two groups of second electric push rods are controlled to drive the two groups of auxiliary clamping plates to clamp and fix the outer walls of the two ends of the guide post, and the two grinding wheels are controlled to press and limit the guide post, so that the position of the guide post is limited and fixed at this time.

[0019] 3. In this invention, after the guide post surface is fully polished, since a polishing cloth is preset on the inner wall of the circular sleeve, the guide post can be inserted into the circular sleeve through the cooperation between the two clamping mechanisms, so that the circular sleeve can polish the outer wall of the guide post after the polishing process, and as the first slider drives the circular sleeve to move back and forth, it is convenient to expand the polishing range of the guide post surface, thereby increasing the speed of subsequent guide post polishing processing, and indirectly improving the efficiency of the entire guide post surface processing.

[0020] 4. In this invention, there are many processing scratches or debris on the surface of the guide post waiting to be polished inside the feeding box. When the guide post between the two clamping mechanisms is undergoing polishing, the two grinding wheels are in an unused state. The double-headed screw can be controlled to drive the two grinding wheels to move away from each other, so that one of the grinding wheels on the right end moves to the bottom of the feeding box, and the corresponding second slider is controlled to drive the grinding wheel to move to the outer wall of the guide post. The grinding wheel is controlled to rotate and is driven to move back and forth with the help of the double-headed screw, so as to facilitate the pre-polishing of the guide post at the bottom of the feeding box. In the subsequent process of pushing the guide post out of the bottom of the feeding box by the push plate, the circular sleeve is used to scrape and clean the debris generated by the surface grinding, so as to improve its grinding efficiency.

The bottom end of the rotating block 12 is connected to a circular sleeve 9 adapted to the outer wall of the guide column through a second electric telescopic rod 13. A first linear motor is preset inside the first slide 10, and the first linear motor can drive the first slider 11 to move back and forth inside the first slide 10; and a second drive device is preset on the outer wall of one side of the first slider 11, and the output end of the second drive device is connected to the rotating part of the rotating block 12, thereby driving the rotating block 12 to rotate and adjust; when the push plate 15 pushes the guide column out from between the two arc plates 14, the guide column will move inside the circular sleeve 9 and automatically scrape the debris on its surface.

[0037] As a technical optimization solution of the present invention, the grinding mechanism includes a double-headed screw 20 rotatably mounted inside the first fixed frame 4, two first movable seats 21 are symmetrically mounted on the surface of the first fixed frame 4, the two first movable seats 21 are both rotatably coordinated with the double-headed screw 20, the tops of the two first movable seats 21 are both mounted with second fixed plates 22, the fronts of the two second fixed plates 22 are both provided with second slides 23, and the interiors of the two second slides 23 are both mounted with second sliders 24. In actual use, a third driving device is preset on one side outer wall of the first fixed frame 4, and the output end of the third driving device is connected to one end of the double-headed screw 20, so that the double-headed screw 20 can be driven to rotate inside the first fixed frame 4, thereby driving the two first movable seats 21 to move toward or away from each other; a second linear motor is preset inside the two second slides 23, and the two second linear motors can drive the two second sliders 24 to move up and down and adjust inside the corresponding heat-generating slide 23.

[0038] As a technical optimization solution of the present invention, a third electric telescopic rod 25 is mounted on the outer wall of each second slider 24 on the side away from the second chute 23. The telescopic ends of the two third electric telescopic rods 25 are mounted on mounting blocks 26, and grinding wheels 6 are mounted inside the mounting blocks 26. A fourth drive device is pre-installed on the outer wall of each mounting block 26. The output ends of the two fourth drive devices are respectively connected to the rotating parts of the two grinding wheels 6, thereby driving the two grinding wheels 6 to rotate and grind the guide column.

[0039] As a technical optimization solution of the present invention, the clamping mechanism includes two second drive screws 27 rotatably mounted inside the second fixed frame 5, the outer walls of the two second drive screws 27 are each mounted with a second movable seat 28, the top of the two second movable seats 28 are each mounted with a mounting plate 31 by two bolt threads, and the top of the two mounting plates 31 are each mounted with two first electric push rods 32. A first servo motor is preset on the outer walls of both sides of the second fixed frame 5, and the output ends of the two first servo motors are respectively connected to one end of the two second drive screws 27, thereby driving the two second drive screws 27 to rotate, and in turn driving the two second movable seats 28 to move back and forth on the surface of the second fixed frame 5; the second movable seat 28 and the mounting plate 31 are detachably mounted by two bolts, which facilitates the replacement of the clamping mechanism above the two mounting plates 31 according to the guide pillars of different thicknesses, and the simultaneous replacement of the loading box 3, making the entire device more applicable when used.

[0040] As a technical optimization solution of the present invention, the telescopic ends of the two first electric push rods 32 are each mounted with a clamping block 30, and the outer walls of both sides of the two clamping blocks 30 are each mounted with a fixing rod 35. The outer wall on the side where the two fixing rods 35 are adjacent is connected to an auxiliary clamping plate 7 via a second electric push rod 36. The two first electric push rods 32 are arranged so that the height of the clamping block 30 can be adjusted by extending and retracting the telescopic ends of the first electric push rods 32. The extension of the telescopic ends of the two sets of second electric push rods 36 drives the two auxiliary clamping plates 7 to move toward each other, thereby assisting in clamping and fixing the end of the guide post to be polished.

[0041] As a technical optimization solution of the present invention, a housing 29 is installed on the outer wall of the two clamping blocks 30 on the side away from each other, and a drive motor 33 is installed inside each of the two housings 29. The output ends of the two drive motors 33 are installed with a grinding block 34, and the two grinding blocks 34 are rotatably installed inside the corresponding clamping blocks 30. The drive motor 33 can drive the grinding blocks 34 to rotate, and the guide column clamped and fixed by the clamping blocks 30 can also rotate. After the two auxiliary clamping plates 7 clamp the guide column, the drive motor 33 drives the grinding blocks 34 to rotate, and the two ends of the guide column can be polished.

[0042] As a technical optimization solution of the present invention, two grinding rods 37 are installed on the outer wall of the adjacent side of the two clamping blocks 30. When in use, the two grinding rods 37 abut the outer wall of the guide post. When the drive motor 33 drives the guide post to rotate together, the parts of the guide post clamped by the auxiliary clamping plate 7 rub against the outer walls of the two corresponding grinding rods 37, thereby grinding the clamped parts of the guide post at both ends, avoiding the formation of dead corners on the guide post surface.

[0043] In the present invention, when the user uses the device, the multiple guide pillars waiting for grinding processing are placed in the interior of the loading box 3 in sequence, and the telescopic ends of the two first electric telescopic rods 17 are controlled to extend, driving one end of the partition 16 to move out from the interior of the loading box 3, so that the guide pillar at the bottom end at this time falls downward to be placed between the two arc plates 14, and then the telescopic ends of the two first electric telescopic rods 17 are controlled to retract, driving one end of the partition 16 to be reset to the interior of the loading box 3, and the two second driving screws 27 are controlled to rotate in sequence, driving the two clamping mechanisms to move closer to each other. The guide post 14 is moved in the direction of rotation so that the distance between the two clamping mechanisms is adapted to the length of the guide column to be ground, and the two hydraulic cylinder telescopic ends preset in the bracket 2 are controlled to extend, pushing the loading box 3 to move to the top of the two clamping mechanisms. At this time, the guide post located between the two arc-shaped plates 14 can be driven by the push plate 15 to push the guide post between the two arc-shaped plates 14 outward from the inside of the circular sleeve 9 by controlling the rotation of the first drive screw 18. When the guide post passes through the inside of the circular sleeve 9, it can automatically clean and scrape off the dirt attached to its outer wall, which is convenient for subsequent grinding processing.

[0044] When the guide column passes through the inside of the circular sleeve 9, the telescopic ends of the two first electric push rods 32 on the top of the two mounting plates 31 are controlled to extend upward together, driving the two clamping blocks 30 to move upward together to a position close to the loading box 3. After the guide column completely passes through the inside of the circular sleeve 9 and falls downward, the guide column can fall on the top of the two grinding rods 37 set on the outer wall of the side close to the two clamping blocks 30 for placement. At this time, the two second drive screws 27 are continued to be controlled to rotate, driving the two clamping blocks 30 to continue to move in the direction of approaching each other, clamping and fixing the two ends of the guide column respectively, thereby achieving the effect of automatic loading of the guide column, and there is no need to manually place the guide column between the two clamping mechanisms.

[0045] After the two ends of the guide column are clamped and fixed by the clamping blocks 30, the telescopic ends of the two third electric telescopic rods 25 can be controlled to extend together, driving the two grinding wheels 6 to move in the direction close to the guide column and abut against the outer wall of the guide column. While controlling the two grinding wheels 6 to rotate, the double-headed screw 20 is controlled to rotate continuously in both directions, driving the two grinding wheels 6 to move in the direction of approaching or moving away from each other, and comprehensively grinding the outer wall of the guide column. At this time, the two ends of the guide column are tightly abutted against the grinding blocks 34 provided inside the two clamping blocks 30. With the help of two driving motors 33, the two grinding blocks 34 are driven to rotate, which can drive the guide column itself to rotate adaptively, making it convenient for the two grinding wheels 6 to comprehensively grind the outer wall of the guide column.

[0046] At the same time, during the process of grinding the guide column, if the guide column needs to be ground more finely, it is necessary to use more fine grinding equipment to grind the guide column. In order to facilitate the improvement of the efficiency of grinding the guide column surface, one of the grinding wheels 6 on the left end can be disassembled and replaced, and replaced with a grinding wheel 6 with a finer surface. After controlling the two grinding wheels 6 to move to abut against the outer wall of the guide column, the two second driving screws 27 can be controlled to rotate in one direction, thereby driving the two clamping mechanisms to move in one direction, driving the clamped guide column to move to the left or right end, and sequentially using the two grinding wheels 6 to perform rough grinding and fine grinding on the guide column surface, thereby further improving the efficiency of the guide column grinding.

[0047] The two second sliders 24 are controlled to drive the two grinding wheels 6 to move downward to press the guide post so that the guide post position is limited and fixed. With the help of the two driving motors 33, the grinding blocks 34 are driven to rotate, and the outer walls of the two ends of the guide post can be polished and processed accordingly, so as to avoid the problem that the two ends of the guide post cannot be polished and processed.

[0048] And in the process of the above-mentioned two grinding wheels 6 grinding the outer wall of the guide column, when the two driving motors 33 drive the grinding block 34 and the guide column to rotate together, the parts of the guide column clamped by the auxiliary splints 7 at both ends can naturally come into friction contact with the outer walls of the two sets of grinding rods 37, so that the parts of the guide column clamped by the auxiliary splints 7 at both ends can also be ground, achieving the effect of comprehensive grinding of the guide column and avoiding the existence of processing dead angles during the guide column grinding process.

[0049] After the surface of the guide column is fully polished, the clamping block 30 and the two auxiliary clamping plates 7 of one of the clamping mechanisms on the right end can be controlled to loosen the restriction on one end of the guide column, and the other two auxiliary clamping plates 7 on the left end can be controlled to continue to clamp and fix the other end of the guide column. Then, the second driving screw 27 on the left end is controlled to rotate, driving the clamping block 30 above it and the clamped guide column to move toward the left end together. Then, the telescopic ends of the two first electric push rods 32 on the left end are controlled to extend upward together, pushing the clamping block 30 and the two auxiliary clamping plates 7 on the right end. The first slide block 11 moves upward together with the clamped guide column, and then the rotating block 12 can be controlled to drive the second electric telescopic rod 13 and the circular sleeve plate 9 to rotate counterclockwise toward the guide column, and the telescopic end of the second electric telescopic rod 13 can be controlled to adapt to the extension and contraction, so that the circular sleeve plate 9 is rotated to the same straight line with the guide column. After the dirt attached to the surface of the circular sleeve plate 9 is washed away by the water outlet mechanism preset near the device, as the first slider 11 moves in the direction away from the loading box 3 inside the first chute 10, the circular sleeve plate 9 is driven by the momentum toward the guide column. The second driving screw 27 at the left end is synchronously controlled to rotate, driving the clamping block 30 above it and the clamped guide column to move slowly toward the right end until the guide column is inserted into the inside of the circular sleeve 9. Then the clamping block 30 at the right end and the two auxiliary clamping plates 7 are controlled to move toward the left end, and the telescopic ends of the two first electric push rods 32 at the right end are controlled to adaptively extend, so that the clamping block 30 at the right end and the auxiliary clamping plate 7 can clamp the right end of the guide column again. Finally, the two sets of auxiliary clamping plates 7 are controlled to release the clamping of the two ends of the guide column. The clamping blocks 30 are tightly in contact with both ends of the guide column, and the two driving motors 33 are controlled to drive the guide column to rotate synchronously. Since a polishing cloth is preset on the inner wall of the circular sleeve 9, it can polish the outer wall of the guide column after grinding processing, and as the first slider 11 drives the circular sleeve 9 to move back and forth, it is convenient to expand the polishing range of the guide column surface. The clamped parts at both ends of the guide column can be polished with the help of other polishing equipment in the future, thereby increasing the speed of subsequent guide column polishing processing and indirectly improving the efficiency of the entire guide column surface processing.

[0050] If there are many processing scratches or debris on the surface of the guide post waiting to be polished inside the feeding box 3, the guide post between the two clamping mechanisms is undergoing polishing operation. At this time, the two grinding wheels 6 are in an unused state. The double-headed screw 20 can be controlled to drive the two grinding wheels 6 to move in the direction away from each other, so that one of the grinding wheels 6 on the right end moves to the bottom of the feeding box 3, and the corresponding second slider 24 is controlled to move upward inside the second slide groove 23, driving the grinding wheel 6 to move until it contacts the outer wall of the guide post between the two arc plates 14, controlling the grinding wheel 6 to rotate, and using the double-headed screw 20 to drive it to move back and forth, so as to facilitate the pre-polishing of the guide post at the bottom end of the feeding box 3, and in the subsequent process of pushing the guide post to be discharged from the bottom end of the feeding box 3 by the push plate 15, the circular sleeve plate 9 is used to scrape and clean the debris generated by the grinding on its surface, so as to improve its grinding efficiency.
