Description

Technical Field

[0001] This utility model relates to the field of molds, and in particular to an injection molding structure for the foot pedal position of a balance scooter accessory injection mold. Background Technology

[0002] Balance bike accessories such as Figure 1 As shown, it includes arc-shaped slots 71 at both ends of the injection molded part 7, multiple reinforcing ribs 72 on the back of the injection molded part 7, and three mounting pieces 73 formed by outward protrusions 411 on the reinforcing ribs 72. The mounting pieces 73 are provided with waist-shaped holes 74.

[0003] When the above-mentioned injection molded parts are injection molded, the demolding direction of the reinforcing ribs is inconsistent with the demolding direction of the arc-shaped slot, and there are many reinforcing ribs, making it difficult to set up a core-pulling structure for demolding; if the inclined ejection method is used directly for demolding, the injection molded parts will interfere with the demolding mechanism of the arc-shaped slot. Utility Model Content

[0004] To facilitate the demolding of self-balancing scooter accessories, this application provides an injection molding structure for the footrest of a self-balancing scooter accessory injection mold.

[0005] The technical solution provided in this application for an injection molding structure of the footrest area in a self-balancing scooter accessory is as follows:

[0006] A self-balancing scooter accessory injection molding structure for foot pedal position includes a moving mold, a fixed mold, two slot core-pulling mechanisms, a first top plate, a molding seat, a connecting rod, a connecting block, an inclined ejector mechanism, and a three mounting hole core-pulling mechanism.

[0007] Two slot core-pulling mechanisms are set on the moving mold to form the arc-shaped slots at both ends of the injection molded part;

[0008] The first top plate is located on the side of the moving mold away from the fixed mold and is driven by a hydraulic cylinder to move along the mold opening and closing direction. The molding seat is used to mold the back of the injection molded part and is fixedly connected to the first top plate through a connecting rod. The inclined ejector mechanism is fixedly connected to the first top plate through a connecting block. The inclined ejector mechanism is set on the molding seat and is used to eject the injection molded part obliquely along the demolding direction. The three mounting hole core-pulling mechanisms are set on the molding seat and are used to mold the three waist-shaped holes on the injection molded part.

[0009] By adopting the above technical solution, after mold opening, the two slot core-pulling mechanisms and the three mounting hole core-pulling mechanisms complete the core pulling first. After that, the hydraulic cylinder drives the first top plate to move, and the first top plate drives the molding seat to move through the connecting rod. At the same time, it drives the inclined ejector mechanism to move through the connecting block. This causes the molding seat to move the entire injection molded part between the moving mold and the fixed mold, avoiding interference between the injection molded part and the arc-shaped slot demolding mechanism on the moving mold. Then, the inclined ejector mechanism ejects the injection molded part obliquely along the demolding direction, completing the demolding.

[0010] Preferably, the connecting rod slides within the moving mold along the mold opening and closing direction, the connecting block is located outside the moving mold, the first top plate extends outward to form at least one protrusion, and the connecting block is fixedly connected to the protrusion by screws; the moving mold is provided with two limiting seats, the first top plate slides between the two limiting seats, the limiting seats are provided with clearance grooves, and the protrusion slides within the clearance grooves.

[0011] By adopting the above technical solution, the connecting rod slides in the moving mold along the mold opening and closing direction, which can ensure the stability of the molding seat when it moves with the first top plate; the connecting block is fixed on the protrusion of the first top plate by screws, realizing a stable connection between the inclined ejector mechanism and the first top plate, and the connecting block is located outside the moving mold, which facilitates the installation and maintenance of the inclined ejector mechanism; the first top plate slides between the two limiting seats, and the limiting seats play a guiding and limiting role in the movement of the first top plate, while the protrusion slides in the relief groove, which further improves the stability of the movement of the first top plate and reduces the deviation.

[0012] Preferably, the mounting hole core-pulling mechanism includes a slanted rod, a first core-pulling block, a spring, and a limiting member. The molding seat has a sliding groove, and the first core-pulling block slides in the sliding groove. The bottom end of the sliding groove and the first core-pulling block each have a groove. The two ends of the spring abut against the inner walls of the two grooves respectively. One end of the slanted rod is fixed to the fixed mold, and the other end of the slanted rod slides on the first core-pulling block in an inclined direction. The limiting member is used to limit the movement distance of the first core-pulling block. When the mold is opened, the slanted rod disengages from the first core-pulling block, and the first core-pulling block moves along the core-pulling direction to a position where it disengages from the slanted rod and stops moving.

[0013] By adopting the above technical solution, when the mold is closed, the inclined rod cooperates with the first core-pulling block, so that the first core-pulling block is in the position of forming the waist-shaped hole, and the spring is compressed; after the mold is opened, the inclined rod drives the first core-pulling block to move along the core-pulling direction to realize the core-pulling of the waist-shaped hole. After the inclined rod disengages from the first core-pulling block, the spring continues to apply force to the first core-pulling block to prevent it from resetting; the limiting component limits the moving distance of the first core-pulling block to ensure that it stops after the core is pulled into place.

[0014] Preferably, the limiting member includes a limiting block and a limiting groove. The limiting block is fixed on the molding seat, and one end of the first core-pulling block extends out of the molding seat. The limiting groove is opened on the side of the first core-pulling block extending out of the molding seat and facing the limiting block. The end of the limiting block is located in the limiting groove.

[0015] By adopting the above technical solution, the limiting block is fixed on the molding seat, and its end is located in the limiting groove of the first core-pulling block. When the first core-pulling block moves under the action of the spring, the limiting block abuts against the inner wall of the limiting groove, which can limit the movement distance of the first core-pulling block. The structure is simple, the limiting effect is stable, and it can effectively prevent the first core-pulling block from affecting subsequent operations due to excessive movement.

[0016] Preferably, the inclined ejector mechanism includes a frame, a second top plate, a first hydraulic cylinder, and a plurality of ejector pins. The frame is fixedly mounted on the forming block, the connecting block is fixed at the bottom of the frame, the first hydraulic cylinder is mounted on the frame and is used to drive the second top plate to move along the ejection direction, one end of the plurality of ejector pins is fixedly mounted on the second top plate, and the other end of the plurality of ejector pins slides inside the forming block.

[0017] By adopting the above technical solution, the frame provides an installation base for the inclined ejector mechanism, and the connecting block fixes the frame to the first top plate, so that the movement of the first top plate can drive the entire inclined ejector mechanism to move synchronously; the first hydraulic cylinder drives the second top plate to move, which in turn drives the ejector pin to slide along the ejection direction. The ejector pin directly acts on the injection molded part to realize the inclined ejection of the injection molded part. The hydraulic cylinder driving force is controllable, the ejection process is stable, and it can meet the demolding requirements of the reinforcing rib.

[0018] Preferably, the slot core-pulling mechanism includes a second hydraulic cylinder, a slider, a second core-pulling block, a fixed rod, a first slide rail, and a second slide rail. The first slide rail is fixedly mounted on the moving mold, the second hydraulic cylinder is fixedly mounted on the first slide rail, the piston rod of the second hydraulic cylinder is fixed on the slider and drives it to slide on the first slide rail, and the second slide rail is fixedly mounted above the first slide rail. The second slide rail has an arc-shaped track arranged along the core-pulling direction, and the second core-pulling block slides on the second slide rail. The slider has a movable groove perpendicular to the core-pulling direction, one end of the fixed rod is fixed to the second core-pulling block, and the other end of the fixed rod extends into the movable groove.

[0019] By adopting the above technical solution, the second hydraulic cylinder drives the slider to slide on the first slide rail. When the slider moves, the fixed rod slides relative to it in the movable groove, causing the second core-pulling block to slide along the arc-shaped path of the second slide rail, thereby realizing the forming and core-pulling of the arc-shaped slot. The arc-shaped path is adapted to the shape of the arc-shaped slot. Through hydraulic cylinder drive and slide rail guidance, the accuracy and stability of the movement of the second core-pulling block are ensured, meeting the forming and demolding requirements of the arc-shaped slot.

[0020] The main technical effects of this utility model are reflected in the following aspects:

[0021] 1. In this utility model, after mold opening, the two slot core-pulling mechanisms and the three mounting hole core-pulling mechanisms first complete the core pulling. After that, the hydraulic cylinder drives the first top plate to move. The first top plate drives the molding seat to move through the connecting rod, and at the same time drives the inclined ejector mechanism to move through the connecting block. This causes the molding seat to move the entire injection molded part between the moving mold and the fixed mold, avoiding interference between the injection molded part and the arc-shaped slot demolding mechanism on the moving mold. Then, the inclined ejector mechanism ejects the injection molded part obliquely along the demolding direction, completing the demolding.

[0022] 2. The connecting rod of this utility model slides within the moving mold along the mold opening and closing direction, ensuring the stability of the forming seat as it moves with the first top plate. The connecting block is fixed to the protrusion on the first top plate by screws, achieving a stable connection between the inclined ejector mechanism and the first top plate. Furthermore, the connecting block is located outside the moving mold, facilitating the installation and maintenance of the inclined ejector mechanism. The first top plate slides between two limiting seats, which guide and limit the movement of the first top plate. The protrusion slides within the clearance groove, further improving the stability of the first top plate's movement and reducing offset.

[0023] 3. In this invention, the second hydraulic cylinder drives the slider to slide on the first slide rail. When the slider moves, the fixed rod slides relative to it in the movable groove, causing the second core-pulling block to slide along the arc-shaped path of the second slide rail, thereby realizing the forming and core-pulling of the arc-shaped slot. The arc-shaped path is adapted to the shape of the arc-shaped slot. Through hydraulic cylinder drive and slide rail guidance, the accuracy and stability of the movement of the second core-pulling block are ensured, meeting the forming and demolding requirements of the arc-shaped slot.

[0032] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0033] This application discloses an injection molding structure for the footrest of a self-balancing scooter accessory.

[0034] Reference Figures 1-4 The present embodiment of a self-balancing scooter accessory injection molding foot pedal position injection molding structure includes a moving mold 1, a fixed mold 2, two slot core pulling mechanisms 3, a first top plate 41, a molding seat 42, a connecting rod 43, a connecting block 44, an inclined ejector mechanism 5, and three mounting hole core pulling mechanisms 6.

[0035] Reference Figures 1-4 Two slot core-pulling mechanisms 3 are set on the moving mold 1 to form the arc-shaped slots 71 at both ends of the injection molded part 7.

[0036] Reference Figures 1-4 The first top plate 41 is located on the side of the moving mold 1 away from the fixed mold 2 and is driven by the oil cylinder to move along the mold opening and closing direction. The molding seat 42 is used to mold the back of the injection molded part 7 and is fixedly connected to the first top plate 41 through the connecting rod 43. The inclined ejector mechanism 5 is fixedly connected to the first top plate 41 through the connecting block 44. The inclined ejector mechanism 5 is set on the molding seat 42 and is used to eject the injection molded part 7 obliquely along the demolding direction. The three mounting hole core pulling mechanism 6 is set on the molding seat 42 and is used to mold the three waist-shaped holes 74 on the injection molded part 7.

[0037] Reference Figures 1-4After mold opening, the two slot core-pulling mechanisms 3 and the three mounting hole core-pulling mechanisms 6 complete the core pulling first. Then, the hydraulic cylinder drives the first top plate 41 to move. The first top plate 41 drives the molding seat 42 to move through the connecting rod 43, and at the same time drives the inclined ejector mechanism 5 to move through the connecting block 44. This causes the molding seat 42 to move the entire injection molded part 7 between the moving mold 1 and the fixed mold 2, avoiding interference between the injection molded part 7 and the arc-shaped slot 71 demolding mechanism on the moving mold 1. Then, the inclined ejector mechanism 5 ejects the injection molded part 7 obliquely along the demolding direction, completing the demolding.

[0038] Reference Figure 2 and Figure 3 The connecting rod 43 slides in the moving mold 1 along the opening and closing direction. The connecting block 44 is located outside the moving mold 1. The first top plate 41 extends outward to form at least one protrusion 411. The connecting block 44 is fixedly connected to the protrusion 411 by screws. The moving mold 1 is provided with two limiting seats 21. The first top plate 41 slides between the two limiting seats 21. The limiting seats 21 are provided with relief grooves 211. The protrusion 411 slides in the relief grooves 211.

[0039] Reference Figure 2 and Figure 3 The connecting rod 43 slides within the moving mold 1 along the mold opening and closing direction, ensuring the stability of the forming seat 42 as it moves with the first top plate 41. The connecting block 44 is fixed to the protrusion 411 of the first top plate 41 by screws, achieving a stable connection between the inclined ejector mechanism 5 and the first top plate 41. The connecting block 44 is located outside the moving mold 1, facilitating the installation and maintenance of the inclined ejector mechanism 5. The first top plate 41 slides between the two limiting seats 21, which guide and limit the movement of the first top plate 41. The protrusion 411 slides within the relief groove 211, further improving the smoothness of the movement of the first top plate 41 and reducing offset.

[0040] Reference Figures 4-6 The mounting hole core-pulling mechanism 6 includes a slanted rod 61, a first core-pulling block 62, a spring 63, and a limiting member. A groove 421 is provided on the molding base 42, and the first core-pulling block 62 slides in the groove 421. Grooves 422 are respectively provided at the bottom end of the groove 421 and on the first core-pulling block 62. The two ends of the spring 63 abut against the inner walls of the two grooves 422 respectively. One end of the slanted rod 61 is fixed on the fixed mold 2, and the other end of the slanted rod 61 slides on the first core-pulling block 62 in the inclined direction. The limiting member is used to limit the movement distance of the first core-pulling block 62. When the mold is opened, the slanted rod 61 disengages from the first core-pulling block 62, and the first core-pulling block 62 moves along the core-pulling direction to the position where it disengages from the slanted rod 61 and stops moving.

[0041] Reference Figures 4-6When the mold is closed, the inclined rod 61 cooperates with the first core-pulling block 62, so that the first core-pulling block 62 is in the position of forming the waist-shaped hole 74, and the spring 63 is compressed. After the mold is opened, the inclined rod 61 drives the first core-pulling block 62 to move along the core-pulling direction, realizing the core-pulling of the waist-shaped hole 74. After the inclined rod 61 disengages from the first core-pulling block 62, the spring 63 continues to apply force to the first core-pulling block 62 to prevent it from resetting. The limiting component limits the movement distance of the first core-pulling block 62 to ensure that it stops after the core is pulled into place.

[0042] Reference Figure 5 The limiting component includes a limiting block 64 and a limiting groove 65. The limiting block 64 is fixed on the molding seat 42. One end of the first core-pulling block 62 extends out of the molding seat 42. The limiting groove 65 is opened on the side of the first core-pulling block 62 extending out of the molding seat 42 and facing the limiting block 64. The end of the limiting block 64 is located in the limiting groove 65.

[0043] Reference Figure 5 The limiting block 64 is fixed on the molding base 42, and its end is located in the limiting groove 65 of the first core-pulling block 62. When the first core-pulling block 62 moves under the action of the spring 63, the limiting block 64 abuts against the inner wall of the limiting groove 65, which can limit the movement distance of the first core-pulling block 62. The structure is simple, the limiting effect is stable, and it can effectively prevent the first core-pulling block 62 from affecting subsequent operations due to excessive movement.

[0044] Reference Figure 5 and Figure 6 To facilitate processing, the molding base 42 can be divided into two parts and fixed together with screws to form a complete molding base 42.

[0045] Reference Figure 5 The inclined ejector mechanism 5 includes a frame 51, a second top plate 52, a first hydraulic cylinder 53, and several ejector pins 54. The frame 51 is fixedly installed on the molding block, and the connecting block 44 is fixed at the bottom of the frame 51. The first hydraulic cylinder 53 is installed on the frame 51 and is used to drive the second top plate 52 to move in the ejection direction. One end of the several ejector pins 54 is fixedly installed on the second top plate 52, and the other end of the several ejector pins 54 slides inside the molding block.

[0046] Reference Figure 5 The frame 51 provides the mounting base for the inclined ejector mechanism 5. The connecting block 44 fixes the frame 51 to the first top plate 41, so that when the first top plate 41 moves, it can drive the entire inclined ejector mechanism 5 to move synchronously. The first hydraulic cylinder 53 drives the second top plate 52 to move, which in turn drives the ejector pin 54 to slide along the ejection direction. The ejector pin 54 directly acts on the injection molded part 7 to realize the inclined ejection of the injection molded part 7. The hydraulic cylinder driving force is controllable, the ejection process is smooth, and it can meet the demolding requirements of the reinforcing rib 72.

[0047] Reference Figure 4 and Figure 7The slot core-pulling mechanism 3 includes a second hydraulic cylinder 31, a slider 32, a second core-pulling block 33, a fixing rod 34, a first slide rail 35, and a second slide rail 36. The first slide rail 35 is fixedly mounted on the moving mold 1. The second hydraulic cylinder 31 is fixedly mounted on the first slide rail 35. The piston rod of the second hydraulic cylinder 31 is fixed on the slider 32 and drives it to slide on the first slide rail 35. The second slide rail 36 is fixedly mounted above the first slide rail 35. The second slide rail 36 has an arc-shaped track arranged along the core-pulling direction. The second core-pulling block 33 slides on the second slide rail 36. The slider 32 has a movable groove 321 perpendicular to the core-pulling direction. One end of the fixing rod 34 is fixed to the second core-pulling block 33, and the other end of the fixing rod 34 extends into the movable groove 321.

[0048] Reference Figure 4 and Figure 7 The second hydraulic cylinder 31 drives the slider 32 to slide on the first slide rail 35. When the slider 32 moves, the fixed rod 34 slides relative to it in the movable groove 321, causing the second core-pulling block 33 to slide along the arc-shaped path of the second slide rail 36, thereby realizing the forming and core-pulling of the arc-shaped slot 71. The arc-shaped path is adapted to the shape of the arc-shaped slot 71. Through the hydraulic cylinder drive and the slide rail guide, the accuracy and stability of the movement of the second core-pulling block 33 are ensured, meeting the forming and demolding requirements of the arc-shaped slot 71.

[0049] Reference Figure 3 and Figure 5 Both the first top plate 41 and the second top plate 52 are composed of two top plates fixed together by bolts. The end of the connecting rod 43 near the first top plate 41 and the end of the ejector pin 54 near the second top plate 52 are integrally formed with cylindrical blocks. One of the top plates has a cylindrical groove on its inner side that mates with the cylindrical block. The two top plates together clamp and position the cylindrical block. The fixed mold 2 has a fixed mold base plate, collectively referred to as fixed mold 2, and the moving mold 1 has a moving mold base plate, collectively referred to as moving mold 1. The above is existing mature technology and will not be described further.

[0050] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
