Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to a drone motor guard net molding equipment. Background Technology

[0002] When a drone is in operation, its high-speed rotor may come into direct contact with the surrounding environment. By installing a drone rotor guard on the outside of the rotor, the safety of people around the drone can be ensured and the rotor can be prevented from colliding with obstacles and being damaged.

[0003] like Figure 1 As shown, the drone protective net is mainly composed of an upper ring frame 11, a lower ring frame 12, an inner protective frame 13, a connecting block 14, and a connecting arm 15. Because the main body of the drone protective net has a hollow design and the frame is relatively thin, it is difficult to form it in one piece, and there is a problem of demolding difficulty.

[0004] Based on this, this utility model designs a drone motor protective net forming device to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, this utility model provides a drone motor protective net forming device.

[0012] A dual-station synchronous control mechanism is set between the base plates of the two sets of protective netting forming mechanisms. The dual-station synchronous control mechanism is used to drive the lower mold changing mechanism of the two sets of protective netting forming mechanisms, so that the lower molds on both sides are in the unfolded and retracted states respectively.

[0013] Furthermore, the active module includes a fixed forming block, a movable forming block, and a slide rod. The fixed forming block is fixedly connected to a fixed truncated cone. The fixed truncated cone has an active groove for moving the movable forming block radially along the fixed truncated cone.

[0016] The adjacent active modules form a second forming cavity for shaping the connecting arm that forms the drone's protective net.

[0017] When the active outer module retracts, the recess between adjacent protrusions forms a third forming cavity for forming the connecting block of the drone protective net;

[0018] The surrounding block, the fixing forming block, and the upper side of the protruding strip constitute the fourth forming cavity of the upper ring frame used to form the drone protective net;

[0019] The surrounding block, the fixed forming block, and the lower side of the protruding strip constitute the fifth forming cavity of the lower ring frame used to form the drone protective net;

[0020] The first molding cavity, the second molding cavity, the third molding cavity, the fourth molding cavity, and the fifth molding cavity work together to form an integrated protective net for drones.

[0021] Furthermore, the lower mold changing mechanism includes a surrounding block guide post, a surrounding block slide groove, a movable forming block guide post, a movable forming block slide groove, and a rotating disk, which is rotatably mounted on the lower end of the base plate via bearings;

[0022] The lower end of the block is fixedly installed with a block guide post, and the rotating disk has multiple block grooves arranged in a circular array that correspond one-to-one with the block guide post and are limited and slidably connected.

Gear rings are fixedly installed on the outer edges of the rotating disks of both sets of protective netting forming mechanisms. The drive structure is set on the substrate, and the output end of the drive structure is fixedly connected to the rack. The lower end of the rack is slidably connected to the substrate, and the left and right sides of the rack are respectively engaged with the gear rings of the two sets of protective netting forming mechanisms.

[0025] Furthermore, when the enclosure blocks and movable forming blocks of one set of protective netting forming mechanisms are fully extended, the enclosure blocks and movable forming blocks of another set of protective netting forming mechanisms are fully retracted.

[0026] Furthermore, the drive structure employs a cylinder.

[0027] Compared with the prior art, the advantages of this utility model are as follows: 1. In this utility model, when the active module and the active outer module are retracted, the upper mold and the lower mold can perform the forming operation of the drone protective net normally; when the active module and the active outer module are unfolded, most of the components of the drone protective net are exposed on the outside of the upper mold and the lower mold, thereby effectively reducing the demolding difficulty of the drone protective net, reducing the friction between the drone protective net and the mold after forming, and increasing the yield of the drone protective net;

[0028] Two sets of protective netting forming mechanisms form two forming stations. After one set of protective netting forming mechanisms completes the forming of the drone protective netting, the moving module and the moving outer module unfold, making it convenient for manual or robotic arms to pick up the material.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0040] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0041] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-7 A drone motor guard net forming equipment, including a substrate 2;

[0042] A set of protective mesh forming mechanism is provided on each of the left and right sides of the substrate 2.

[0043] The protective net forming mechanism includes a base plate 3, an upper mold 4, and a lower mold 5. The upper mold 4 is provided on the base plate 3, and the lower mold 5 is provided with an injection flow channel. The upper mold 4 and the lower mold 5 are used to cooperate in forming the drone protective net 1.

[0044] The lower mold 5 includes a fixed truncated cone 51, a fixed inner module 52, a movable module 53, and a movable outer module 54. The fixed truncated cone 51 is fixedly connected to the base plate 3. The fixed inner module 52 is fixedly installed in the middle of the fixed truncated cone 51. Multiple movable outer modules 54 that can move radially along the fixed truncated cone 51 are arranged in a circular array on the outer side of the fixed truncated cone 51. Multiple movable modules 53 are also arranged between the fixed inner module 52 and the movable outer module 54. The movable modules 53 are arranged in a circular array and can move radially along the fixed truncated cone 51. The fixed inner module 52 and the movable modules 53 form a first forming cavity for forming the inner frame 13 of the UAV protective net 1. The adjacent movable modules 53 form a second forming cavity for forming the connecting arm 15 of the UAV protective net 1.

[0045] The lower end of the base plate 3 is provided with a lower mold changing mechanism 6 for controlling the synchronous contraction or expansion of the movable module 53 and the movable outer module 54 along the radial direction of the fixed frustum 51;

[0046] A dual-station synchronous control mechanism 7 is provided between the base plates 3 of the two sets of protective netting forming mechanisms. The dual-station synchronous control mechanism 7 is used to drive the lower mold changing mechanism 6 of the two sets of protective netting forming mechanisms so that the lower molds 5 on both sides are in the unfolded and retracted states respectively.

[0047] In this invention, when the movable module 53 and the movable outer module 54 are retracted, the upper mold 4 and the lower mold 5 can perform the molding operation of the drone protective net 1 normally; when the movable module 53 and the movable outer module 54 are unfolded, most of the components of the drone protective net 1 are exposed outside the upper mold 4 and the lower mold 5, thereby effectively reducing the demolding difficulty of the drone protective net 1, reducing the friction between the drone protective net 1 and the mold after molding, and increasing the yield of the drone protective net 1.

[0048] Two sets of protective net forming mechanisms form two forming stations. After one set of protective net forming mechanisms completes the forming of the drone protective net 1, the movable module 53 and the movable outer module 54 are unfolded to facilitate manual or robotic arm material handling. Meanwhile, the movable module 53 and the movable outer module 54 of the other set of protective net forming mechanisms are retracted to perform the forming operation of the drone protective net 1, thereby effectively improving the forming effect of the drone protective net 1, reducing equipment downtime, and conforming to the production rhythm of the drone protective net 1.

[0049] The active module 53 includes a fixed forming block 531, a movable forming block 533, and a slide bar 534. The fixed forming block 531 is fixedly connected to a fixed truncated cone 51. The fixed truncated cone 51 has an active groove 532 for the movable forming block 533 to move radially along the fixed truncated cone 51. The slide bar 534 is fixedly installed at one end of the movable forming block 533 near the fixed forming block 531. The slide bar 534 is slidably connected to the fixed forming block 531.

[0050] The movable outer module 54 includes a surrounding block 541 and a protrusion 542. The protrusion 542 is fixedly installed at one end of the surrounding block 541 near the fixed inner module 52. The two ends of the protrusion 542 are symmetrically provided with recesses 543. A limit block 545 is fixedly installed at the lower end of the surrounding block 541. A limit groove 544 is opened on the base plate 3. The limit block 545 and the limit groove 544 are slidably connected. The surrounding block 541 can move radially along the fixed frustum 51 through the cooperation of the limit groove 544 and the limit block 545.

[0051] When the active outer module 54 retracts, the recess 543 between adjacent protrusions 542 forms a third forming cavity for forming the connecting block 14 of the UAV protective net 1;

[0052] The upper side of the surrounding block 541, the fixing forming block 531, and the protrusion 542 constitutes the fourth forming cavity for forming the upper ring frame 11 of the UAV protective net 1.

[0053] The lower side of the surrounding block 541, the fixing forming block 531, and the protrusion 542 constitutes the fifth forming cavity for forming the lower ring frame 12 of the UAV protective net 1;

[0054] The first molding cavity, the second molding cavity, the third molding cavity, the fourth molding cavity, and the fifth molding cavity work together to achieve the integrated molding of the UAV protective net 1.

[0055] The lower mold changing mechanism 6 includes a surrounding block guide post 61, a surrounding block slide groove 62, a movable forming block guide post 63, a movable forming block slide groove 64, and a rotating disk 65. The rotating disk 65 is rotatably mounted on the lower end of the base plate 3 via bearings.

[0056] The lower end of the enclosure block 541 is fixedly installed with an enclosure block guide post 61, and the rotating disk 65 has multiple enclosure block grooves 62 arranged in a circular array that correspond one-to-one with the enclosure block guide post 61 and are limited and slidably connected.

[0057] The lower end of the movable molding block 533 is fixedly installed with a movable molding block guide post 63, and the rotating disk 65 has a plurality of movable molding block grooves 64 arranged in a circular array, which correspond one-to-one with the movable molding block guide post 63 and are limited and slidably connected.

[0058] When the rotating disk 65 is rotated, the guide post 61 and the slide groove 62 of the surrounding block cooperate to control the radial movement of the surrounding block 541 along the fixed frustum 51, and the guide post 63 and the slide groove 64 of the movable forming block cooperate to control the radial movement of the movable forming block 533 along the fixed frustum 51, thereby realizing the synchronous contraction and expansion of the surrounding block 541 and the movable forming block 533. When the surrounding block 541 and the movable forming block 533 contract, the upper mold 4 and the lower mold 5 cooperate to realize the integral molding of the drone protective net 1. When the surrounding block 541 and the movable forming block 533 expand, most of the drone protective net 1 is exposed outside the upper mold 4 and the lower mold 5, which effectively reduces the demolding difficulty of the drone protective net 1 and reduces the friction between the drone protective net 1 and the mold after molding, thereby increasing the yield of the drone protective net 1.

[0059] The dual-station synchronous control mechanism 7 includes a cylinder 71, a rack 72, and a gear ring 73. Gear rings 73 are fixedly installed on the outer edges of the rotating disks 65 of both sets of protective net forming mechanisms. The cylinder 71 is fixedly installed on the base plate 2, and the output end of the cylinder 71 is fixedly installed with the rack 72. The lower end of the rack 72 is slidably connected to the base plate 2, and the left and right sides of the rack 72 are respectively engaged with the gear rings 73 of the two sets of protective net forming mechanisms. The cylinder 71 pushes the rack 72, so that the gear rings 73 on both sides rotate synchronously in opposite directions. When the surrounding block 541 and the movable forming block 533 of one set of protective net forming mechanisms are fully extended, the surrounding block 541 and the movable forming block 533 of the other set of protective net forming mechanisms are fully retracted.

[0060] In some embodiments, the cylinder 71 is replaced by a push rod, and the operator can directly push the rack 72 through the push rod to drive the rotating disk 65 to rotate.

[0061] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
