Description

Technical Field

[0001] This utility model belongs to the field of cold pressing mold processing technology, specifically a CNC engraving device for processing the curved surface of cold pressing mold cavity. Background Technology

[0002] In the field of cold-press mold manufacturing, five-axis CNC swivel head engraving machines, with their superior multi-axis linkage capabilities, can achieve high-precision machining of complex curved surfaces inside cold-press mold cavities, effectively improving the manufacturing quality and efficiency of molds. However, in actual production processes, after the five-axis CNC swivel head engraving machine completes the surface machining of the cold-press mold, the engraving machine must be stopped first. Then, the finished cold-press mold and fixture must be unlocked and removed before a new cold-press mold can be placed and fixed with fixtures. This makes it difficult for traditional engraving machines to perform continuous work, thereby reducing the production efficiency of cold-press molds. To address this, we propose a CNC engraving device for machining curved surfaces of cold-press mold cavities. Utility Model Content

[0003] The purpose of this invention is to provide a CNC engraving device for machining the curved surface of a cold-pressed mold cavity, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a CNC engraving device for machining the curved surface of a cold-pressed mold cavity, comprising a five-axis CNC swivel head engraving machine. A rotating plate is mounted on the top of the machining table of the five-axis CNC swivel head engraving machine. A first mounting groove is provided inside the rotating plate. A set of sliding grooves is provided through the left and right sides of the first mounting groove. A bidirectional lead screw and a worm gear are rotatably arranged in the first mounting groove. Two sets of internal threaded sliders are evenly screwed onto the outer wall of the bidirectional lead screw. A set of locking plates is provided on the opposite sides of the two sets of internal threaded sliders. A first servo motor is provided on the front side of the rotating plate. The output end of the first servo motor passes through the front side of the rotating plate and is connected to the worm gear. A worm wheel meshes with the bottom of the worm gear. A through hole is provided through the right side of the worm wheel. The middle part of the bidirectional lead screw is located in the through hole.

[0005] Preferably, the bottom of the rotating plate is provided with a limit post, the bottom of the limit post is provided with a second servo motor, and a set of locking blocks are placed on both the left and right sides of the rotating plate. The side of the locking plate away from the internal thread slider is set in the slide groove, and the outer side wall of the locking block is provided with a locking groove. The locking plate corresponds to the locking groove.

[0006] Preferably, the top of the processing table of the five-axis CNC swivel head engraving machine is provided with a limiting groove, the bottom of the limiting groove is provided with a second mounting groove, the right side of the second mounting groove is provided with a heat dissipation groove, the second servo motor is provided in the second mounting groove, and the limiting post is provided in the limiting groove.

[0007] Preferably, the internal threaded slider is slidably disposed in the first mounting groove of the rotating plate, a bracket is disposed on the right side of the rotating plate, a locking block located on the left side of the rotating plate is disposed on the top of the processing table of the five-axis CNC swivel head engraving machine, a locking block located on the right side of the rotating plate is disposed on the top of the bracket, and the bottom right side of the rotating plate is located on the top of the bracket.

[0008] Preferably, two sets of clamping assemblies are evenly installed on the top of the rotating plate. Each clamping assembly includes a support frame, and hydraulic rods are evenly arranged on the top of the support frame. A clamping plate is arranged on the outer side of the telescopic end of the hydraulic rod, and a guide post is arranged on the outer side of the clamping plate. The clamping plate is located on the inner side of the support frame, and guide holes are evenly opened through the outer wall of the support frame. The guide post passes through the guide hole.

[0009] Preferably, the two sets of support frames are respectively arranged on the top left and right sides of the rotating plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are: by using a rotatable rotating plate in conjunction with two sets of clamping components, when the five-axis CNC swivel head engraving machine is processing a set of cold pressing molds, another set of cold pressing molds can be installed on the rotating plate. Then, when the processing of a set of cold pressing molds is completed, the positions of the two sets of cold pressing molds can be quickly switched, thereby realizing the continuous operation of the five-axis CNC swivel head engraving machine and thus improving production efficiency.

[0011] The first servo motor drives the worm and worm wheel, which in turn drives the locking plate to insert into the locking groove of the locking block, thereby locking the rotating plate. This ensures that the rotating plate is in a stable state when the cold pressing mold is being processed. Furthermore, the self-locking property of the worm wheel and worm can improve the insertion stability of the locking block, making the locking of the rotating plate more reliable and thus improving the reliability of the device.

[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] Please see Figure 1-4A CNC engraving device for machining the curved surface of a cold-pressed mold cavity includes a five-axis CNC swivel head engraving machine 1. A rotating plate 11 is placed on top of the machining table of the five-axis CNC swivel head engraving machine 1. A first mounting groove is opened inside the rotating plate 11. A set of sliding grooves is opened through both the left and right sides of the first mounting groove. A bidirectional lead screw 142 and a worm gear 141 are rotatably arranged in the first mounting groove. Two sets of internal threaded sliders 144 are evenly screwed to the outer wall of the bidirectional lead screw 142. A set of locking plates 145 are fixedly arranged on the opposite sides of the two sets of internal threaded sliders 144. A first servo motor 14 is fixedly arranged on the front side of the rotating plate 11. The output end of the first servo motor 14 passes through the front side of the rotating plate 11 and is connected to the worm gear 141. A worm wheel 143 is meshed at the bottom of the worm gear 141. A through hole is opened through the right side of the worm wheel 143. The middle part of the bidirectional lead screw 142 is fixedly arranged in the through hole. A limit post 16 is fixedly arranged at the bottom of the rotating plate 11. A second servo motor 15 is fixedly installed at the bottom of the 6. The second servo motor 15 drives the limiting post 16 to rotate 180 degrees, thereby driving the rotating plate 11 to rotate 180 degrees. A set of locking blocks 13 is installed on both the left and right sides of the rotating plate 11. The locking plate 145 is slidably installed in the groove on the side away from the internal thread slider 144. The outer wall of the locking block 13 has a through locking groove. The locking plate 145 corresponds to the locking groove. The first servo motor 14 drives the worm gear 141 to rotate, and the worm gear 141 drives the worm wheel 143 to rotate. Since the worm wheel 143 is fixedly sleeved on the outer ring of the double-acting screw 142, the worm wheel 143 drives the double-acting screw 142 to rotate, thereby driving the two sets of internal thread sliders 144 to move outward synchronously. Then, the internal thread sliders 144 drive the locking plate 145 to insert into the locking groove of the locking block 13, thereby locking the rotating plate 11.

[0022] The top of the processing table of the five-axis CNC swivel head engraving machine 1 is provided with a limiting groove, and a second mounting groove is provided at the bottom of the limiting groove. A heat dissipation groove is evenly provided through the right side of the second mounting groove. The second servo motor 15 is fixedly installed in the second mounting groove. The limiting post 16 is rotatably installed in the limiting groove. The internal thread slider 144 is slidably installed in the first mounting groove of the rotating plate 11. A bracket 12 is fixedly installed on the right side of the rotating plate 11. The locking block 13 located on the left side of the rotating plate 11 is fixedly installed on the top of the processing table of the five-axis CNC swivel head engraving machine 1. The locking block 13 located on the right side of the rotating plate 11 is fixedly installed on the top of the bracket 12. The bottom right side of the rotating plate 11 is located on the top of the bracket 12.

[0023] Two sets of clamping assemblies 300 are evenly installed on the top of the rotating plate 11. Each clamping assembly 300 includes a support frame 3. A hydraulic rod 31 is evenly fixedly installed on the top of the support frame 3. A clamping plate 33 is fixedly installed on the outer side of the telescopic end of the hydraulic rod 31. A guide post 32 is fixedly installed on the outer side of the clamping plate 33. The clamping plate 33 is located inside the support frame 3. Guide holes are evenly opened through the outer wall of the support frame 3. The cold pressing mold is placed on the rotating plate 11 and placed inside the support frame 3. The clamping plate 33 is clamped and fixed by the hydraulic rod 31. The guide post 32 assists in the stable movement of the clamping plate 33 and passes through the guide hole. The two sets of support frames 3 are fixedly installed on the left and right sides of the top of the rotating plate 11, respectively.

[0024] Working principle: The cold pressing mold is placed on the rotating plate 11 and positioned within the support frame 3. The hydraulic rod 31 drives the clamping plate 33 to clamp and fix the cold pressing mold. The guide column 32 assists in the stable movement of the clamping plate 33. The first servo motor 14 drives the worm gear 141 to rotate, which in turn drives the worm wheel 143 to rotate. Since the worm wheel 143 is fixedly sleeved on the outer ring of the bidirectional lead screw 142, the worm wheel 143 drives the bidirectional lead screw 142 to rotate. This causes the bidirectional lead screw 142 to drive the two sets of internal thread sliders 144 to move outward synchronously. In turn, the internal thread sliders 144 drive the locking plate 145 to insert into the locking groove of the locking block 13, thereby locking the rotating plate 11.

[0025] First, a set of cold-pressed molds is clamped and fixed using the clamping assembly 300 on the top left side of the rotating plate 11, so that the five-axis CNC swivel head engraving machine 1 can perform cavity surface processing on the molds. During this process, the worker can place the new cold-pressed mold on the top right side of the rotating plate 11 and clamp and fix it using the clamping assembly 300 on the top right side of the rotating plate 11. After the five-axis CNC swivel head engraving machine 1 finishes processing the cold-pressed mold on the top left side of the rotating plate 11, the first servo motor 14 reverses to drive the locking plate 145 to separate from the locking block 13, thereby unlocking the rotating plate 11. Then, the second servo motor 15 drives the limit column 16 to rotate 180 degrees, thereby driving the rotating plate 11 to rotate 180 degrees, so that the two sets of cold-pressed molds on the top of the rotating plate 11 are swapped, so that the five-axis CNC swivel head engraving machine 1 can process the new cold-pressed mold. During this process, the worker can remove the processed cold-pressed mold.
