Description

Technical Field

[0001] This utility model belongs to the field of injection mold technology and relates to a core-pulling mechanism for the outer slider of a motorcycle seat cover injection mold. Background Technology

[0002] The front cover of a motorcycle is a crucial component, located under the seat and providing excellent protection. It is typically manufactured using injection molds. However, due to the large size of the front cover, its extensions on both sides, and the complex curvature of these extensions, a sliding block core-pulling mechanism is required for demolding and mold opening. Existing technology, such as the one disclosed in patent publication number CN211279580U, describes an external sliding block core-pulling mechanism for a motorcycle instrument panel injection mold, belonging to the field of injection molds. It includes an upper injection mold body, with fixed sliding blocks fixedly connected to both sides. Each fixed sliding block contains a movable core-pulling block, and a hydraulic cylinder is connected to one side of each movable core-pulling block. The movable core-pulling block can reciprocate linearly along the main axis of the hydraulic cylinder. The movable core-pulling block also has an internal core-pulling rod perpendicular to the main axis of the hydraulic cylinder. As the movable core-pulling block gradually moves out of the fixed sliding block along the main axis of the hydraulic cylinder, the internal core-pulling rod gradually moves out of the upper injection mold body along the direction perpendicular to the movable core-pulling block's movement.

[0003] The disadvantages of the above-mentioned core-pulling mechanism are: it is driven by a single hydraulic cylinder, which requires an additional hydraulic station to supply hydraulic oil for power output, increasing the space occupied; secondly, during the core-pulling process, the stability of the moving core-pulling block along the main axis of the hydraulic cylinder cannot be guaranteed, and it is easily affected by the vibration of the hydraulic cylinder. Therefore, we designed a core-pulling mechanism for the outer slider of the injection mold of the motorcycle seat cover. Summary of the Invention

[0004] The purpose of this invention is to provide a core-pulling mechanism for the outer slider of the injection mold of the front cover of a motorcycle seat, so as to solve the problems mentioned in the background art.

[0005] The purpose of this utility model can be achieved through the following technical solution: a motorcycle seat cover injection mold external slider core pulling mechanism, including an upper mold body, a lower mold body and a seat cover mold core, the seat cover mold core is located at the top of the lower mold body and the upper mold body and the lower mold body are connected by the seat cover mold core, and an external slider core pulling mechanism is provided on one side of the lower mold body.

[0006] The outer slider core-pulling mechanism includes a mold core insert, an insert sliding block, an outer slider, a double-headed electric cylinder base, and two electric pulling cylinders. The outer slider is assembled at the opening on one side of the lower mold body of the front cover, and an insert slider groove is opened on the top of the outer slider. The insert sliding block is slidably connected to the outer slider through the insert slider groove. The mold core insert is set on the side of the insert sliding block and corresponds to the front cover mold core of the seat barrel. The double-headed electric cylinder base is connected to one side of the lower mold body of the front cover through a bracket. The two electric pulling cylinders are bolted to two mounting seats of the double-headed electric cylinder base. A slider pulling rod is installed at one end of the outer slider, and an electric cylinder connecting plate is provided at one end of the slider pulling rod. The output shafts of the two electric pulling cylinders are both keyed to the electric cylinder connecting plate. An inclined guide groove is provided on both sides of the insert slider groove, and an inclined guide block is provided on both sides of the insert sliding block. The insert sliding block corresponds to each inclined guide groove through two inclined guide blocks.

[0007] The aforementioned motorcycle seat front cover injection molding outer slider core-pulling mechanism also includes two slider sliding strips. These two sliding strips are located at the two edges of the opening on one side of the lower mold body of the front cover, and each sliding strip has a straight groove on its inner side. Slider guide strips are provided on both sides of the outer slider, and the outer slider corresponds to the straight grooves of the two sliding strips via the two slider guide strips. This design aims to ensure good linear motion accuracy of the outer slider during its linear movement, reduce the possibility of deviation, minimize fluctuations during movement, and ensure the stability of the insert sliding block during operation.

[0008] In the aforementioned motorcycle seat front cover injection molding outer slider core-pulling mechanism, the length of the slider guide strip is not less than the length of the side edge of the outer slider, and the length of the slider guide strip is three-quarters of the length of the straight slide groove. This design ensures good structural stability when the outer slider is connected to the slider sliding pressure strip via two slider guide strips, guaranteeing that the outer slider can slide smoothly along the slider sliding pressure strip without detaching from it.

[0009] In the aforementioned motorcycle seat front cover injection molding outer slider core-pulling mechanism, auxiliary sliding seats are installed at both ends of the electric cylinder connecting plate. A track bar is slidably mounted on one end of each of the two auxiliary sliding seats, and the two track bars are located on either side of the top of the double-headed electric cylinder base. This design aims to ensure good motion stability of the electric cylinder connecting plate during operation, reducing the vibration impact caused by the vibration of the two electric cylinders themselves. This reduces the shaking effect of the slider pulling rod, resulting in stable pulling of the outer slider.

[0010] In the aforementioned motorcycle seat front cover injection molding outer slider core-pulling mechanism, an oil reservoir is provided at the head notch of one of the inclined guide grooves, and two oil outlet tips are provided at the bottom of the oil reservoir. A slider buckle is provided on one side of the oil reservoir, and the oil reservoir is connected to the outer slider through the slider buckle. The purpose of this arrangement is to provide a certain lubrication effect. When the insert sliding block slides along the insert slider groove of the outer slider, the inclined guide block of the insert sliding block can contact and cause the ball bearings inside the oil outlet tips to slide. Lubricating oil flows out along the sliding ball bearings, lubricating the inclined guide groove and the insert slider groove, reducing friction and making the movement smoother.

[0011] Compared with the prior art, the advantages of the external slider core-pulling mechanism of the motorcycle seat front cover injection mold of this utility model are as follows: By setting the external slider core-pulling mechanism including mold core insert, insert sliding block, external slider, double-headed electric cylinder seat and two electric cylinders, and using two electric cylinders for drive, the space occupied by the configuration required by the hydraulic cylinder drive is avoided. It not only ensures good driving force, but also provides inclined guide grooves on both sides of the insert slider groove and inclined guide blocks on both sides of the insert sliding block. The insert sliding block corresponds to each inclined guide groove through the two inclined guide blocks, and with the cooperation of the auxiliary sliding seat and the track, it achieves good motion stability and reduces the vibration effect caused by the vibration of the two electric cylinders themselves. This can reduce the shaking effect of the slider pulling rod, so that it moves smoothly and stably along the main axis of the electric cylinder, making the external slider pull stable.

[0012] An oil reservoir is installed at the head notch of one of the inclined guide grooves. Two oil outlet tips are installed at the bottom of the oil reservoir, which has a certain lubrication effect. When the insert sliding block slides along the insert slider groove of the outer slider, the inclined guide block of the insert sliding block can contact and make the ball inside the oil outlet tip slide. The lubricating oil flows out along the sliding ball, lubricating the inclined guide groove and the insert slider groove, reducing friction and making the movement smoother.

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model relates to an external slider core-pulling mechanism for the injection mold of a motorcycle seat front cover.

[0020] Injection molds include, but are not limited to, front cover upper mold body 1, front cover lower mold body 2, and seat barrel front cover mold core 3. The seat barrel front cover mold core 3 is located at the top of the front cover lower mold body 2 and the front cover upper mold body 1 and front cover lower mold body 2 are connected by the seat barrel front cover mold core 3. It may also include mold base, sprue, mold core insert and mold opening assembly, etc., which are required in the prior art.

[0021] Example 1: An external slider core-pulling mechanism is provided on one side of the front cover lower mold body 2; the external slider core-pulling mechanism includes a mold core insert 4, an insert sliding block 5, an external slider 6, a double-headed electric cylinder seat 7 and two electric cylinders 8. The external slider 6 is assembled at the opening on one side of the front cover lower mold body 2 and an insert slider groove 9 is opened on the top of the external slider 6. The insert sliding block 5 is slidably connected to the external slider 6 through the insert slider groove 9. The mold core insert 4 is set on the side of the insert sliding block 5 and corresponds to the front cover mold core 3 of the seat barrel.

[0022] The double-headed electric cylinder base 7 is connected to one side of the lower mold body 2 of the front cover through a bracket. The two electric cylinders 8 are installed at the two mounting seats of the double-headed electric cylinder base 7 by bolts. One end of the outer slider 6 is equipped with a slider pulling rod 13. One end of the slider pulling rod 13 is provided with an electric cylinder connecting plate 14. The output shafts of the two electric cylinders 8 are both keyed to the electric cylinder connecting plate 14. The two sides of the insert slider groove 9 are provided with inclined guide grooves 17. The two sides of the insert sliding block 5 are provided with inclined guide blocks 18. The insert sliding block 5 corresponds to each inclined guide groove 17 through the two inclined guide blocks 18.

[0023] In terms of structural design, the insert slider groove 9 is an inclined structure, with the height of the part near the slider pull rod 13 being higher than the height of the part away from the slider pull rod 13. This design allows the insert slider block 5 to generate a downward oblique movement trajectory, thereby enabling the mold core insert 4 to separate from the seat barrel front cover mold core 3.

[0024] Furthermore, in this scheme, in order to make the electric cylinder connecting plate 14 have good motion stability, auxiliary sliding seats 15 are installed at both ends of the electric cylinder connecting plate 14, and a track bar 16 is slidably arranged at one end of each of the two auxiliary sliding seats 15. The two track bars 16 are located on both sides of the top of the double-headed electric cylinder base 7.

[0025] When the electric cylinder connecting plate 14 is driven by the two electric cylinders 8, it moves toward the electric cylinders 8. Since the two auxiliary sliding seats 15 slide inside the corresponding track bars 16, the linear motion of the electric cylinder connecting plate 14 has high precision and good stability.

[0026] Example 2: It also includes two slider sliding pressure strips 10, which are located at the two edges of the opening on one side of the front cover lower mold body 2. Each slider sliding pressure strip 10 has a straight groove 11 on its inner side. Both sides of the outer slider 6 are provided with slider guide strips 12. The outer slider 6 corresponds to the straight grooves 11 of the two slider sliding pressure strips 10 through the two slider guide strips 12. The length of the slider guide strip 12 is not less than the length of the side edge of the outer slider 6 and the length of the slider guide strip 12 is three-quarters of the length of the straight groove 11.

[0027] In this embodiment, the outer slider 6 has good linear motion accuracy during linear motion, reducing the possibility of the outer slider 6 deviating, and at the same time reducing the fluctuation effect of the outer slider 6 during motion, thus ensuring the stability of the insert sliding block 5 during motion.

[0028] Example 3: An oil reservoir 19 is provided at the head notch of one of the inclined guide grooves 17, and two oil dispensing tips 20 are provided at the bottom of the oil reservoir 19; a slider buckle 21 is provided on one side of the oil reservoir 19, and the oil reservoir 19 is fastened to the outer slider 6 through the slider buckle 21.

[0029] The ink dispenser tip 20 is similar to that of a ballpoint pen in the prior art. Its oil reservoir 19 stores lubricating oil and uses the internal ball bearings of the ink dispenser tip 20 to achieve a seal. When the internal ball bearings of the ink dispenser tip 20 roll, a gap is created. Due to the effects of gravity and relative friction, the lubricating oil can flow out through the gap into the inclined guide groove 17.

[0030] In use: The lower mold body 2 of the front cover is connected to the upper mold body 1 of the front cover through the front cover mold core 3 of the seat barrel for injection molding production of the front cover. The additionally configured mold base, sprue, mold core insert, and mold opening assembly enable effective mold opening and injection molding processes. When core pulling is required after injection molding (synchronized with the mold opening step), two electric cylinders 8 (two electric cylinders 8 of the same model and stroke) are activated. The two electric cylinders 8 move synchronously, driving the electric cylinder connecting plate 14 to move linearly, moving the outer slider 6 along the two slider sliding pressure strips 10, gradually moving away from the lower mold body 2 of the front cover. Because the outer slider 6 is equipped with insert slider grooves 9, this structure is inclined. The inclined structure allows the outer slider 6 to move along a downward trajectory due to the track effect of the insert slider groove 9, thus enabling the insert slider 5 to separate from the mold core insert 4 and the front cover mold core 3. This solution uses two electric cylinders 8 for driving, avoiding the space occupation caused by the configuration required by the hydraulic cylinder drive. It not only ensures good driving force but also provides good motion stability and reduces the vibration caused by the vibration of the two electric cylinders 8 themselves. This reduces the shaking effect of the slider pulling rod 13, making its movement along the main axis of the electric cylinder 8 smooth and stable, thus making the movement of the outer slider 6 stable.
