Description

Technical Field

[0001] The invention relates to the technical field of injection molding, in particular to an injection molding device for an automobile sunroof handle. Background Art

[0002] A car sunroof typically consists of one or more large pieces of glass, covering most of the roof area. This provides a wide field of view, enhances the sense of airiness, and improves the passenger experience. However, due to the large glass area, its insulation and sunshade properties may be relatively weak, often requiring the use of an inward-pull sliding curtain panel. The sunroof handle is a key component of the sliding curtain panel and is manufactured through injection molding.

[0003] Moreover, the existing injection molding processing equipment for automobile sunroof handles has the following disadvantages: 1. The corresponding mold is often fixedly connected to the corresponding body part with bolts, which is inconvenient to disassemble. During assembly, the bolts need to be tightened in sequence. During this process, the corresponding mold needs to be kept fixed to the corresponding part of the body, which is inconvenient to operate; 2. It is not convenient to demold the material after injection molding. If manual demolding is used, burns are likely to occur. Moreover, if the material is not completely molded or the demolding is not thorough, it is inconvenient to clean the mold; 3. The corresponding mold can be disassembled and assembled after the body stops at any position. If the body stops when the distance between the two sets of molds is small, it may even be necessary to start the propeller again to adjust the distance between the two sets of molds when disassembling the mold to increase the operating space. Danger is prone to occur during this process. Summary of the Invention

DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] See also Figures 1-13 An injection molding device for an automobile sunroof handle includes a workbench 1, an injector 2, a first bracket 3, and a second bracket 4, wherein the injector 2, the first bracket 3, and the second bracket 4 are sequentially arranged on the workbench 1, and further includes:

[0040] The workbench 1 provides stable support for the first bracket 3, the second bracket 4 and the injector 2. The injector 2 is an injector 2 for injection molds on the market, which will not be described in detail in this article.

[0041] A fixed module, the fixed module includes a fixed mold 5, a first positive and negative threaded screw 6, a first limit block 7 and a first gear 8. The first bracket 3 is provided with a first slot at the lower part near one end of the second bracket 4, and a first slide groove is further provided in the lower part of the first slot. The positive and negative threaded screws on the left and right sides pass through the side walls of the first slide groove and are connected to the center of the first gear 8. The first limit blocks 7 are arranged in two groups symmetrically. The lower part of the first limit blocks 7 is inserted into the first slide groove and is threadedly connected to the first positive and negative threaded screw 6. The fixed mold 5 is L-shaped. The lower part of the fixed mold 5 is inserted into the first slot and is provided with a first card groove adapted to the upper part of the first limit block 7. The output end of the injector 2 passes through the first bracket 3 and is connected to the input end of the fixed mold 5;

[0042] In the fixed mold assembly, rotate the first gear 8. Since the first forward and reverse screw 6 is connected to the center of the first gear 8, the first forward and reverse screw 6 rotates accordingly. The lower part of the first limit block 7 is inserted into the first slide groove and is threadedly connected to the first forward and reverse screw 6, so the first limit block 7 will move toward or away from each other in the first slide groove. When installing the fixed mold 5, insert the lower part of the fixed mold 5 into the first slot, and then rotate the first gear 8 to move the two groups of first limit blocks 7 toward each other until they are stuck in the first slot of the fixed mold 5, completing the installation of the fixed mold 5. When disassembling, rotate the first gear 8 in the opposite direction to move the first limit block 7 away from the first slot, and then remove the fixed mold 5;

[0043] The mold clamping assembly includes a propeller 9, a mobile frame 10, a mobile module, a slide 11 and a first rack 12. The propeller 9 passes through the second bracket 4 and is connected to one end of the mobile frame 10. The other end of the mobile frame 10 is provided with a mobile module for clamping with the fixed mold 5. The slides 11 are symmetrically arranged on the left and right sides below the mobile frame 10. The end of the slide 11 away from the mobile frame 10 is provided with a first rack 12 adapted to the first gear 8;

[0044] The pusher 9 pushes the movable frame 10 toward the fixed mold 5 with the support of the second bracket 4. At this time, the slide 11 drives the first rack 12 to move with the movable frame 10. The output end of the movable module completes the mold closing with the fixed mold 5, and then the injection operation is performed. When the fixed mold 5 needs to be disassembled, the pusher 9 contracts, and the slide 11 drives the first rack 12 to move toward the second bracket 4. The first rack 12 contacts and engages with the first gear 8. The first gear 8 drives the first forward and reverse screw 6 to rotate, and the two groups of first limit blocks 7 move toward each other. The first limit block 7 exits the first slot. At this time, the fixed mold 5 can be disassembled. After replacing the new fixed mold 5, as the pusher 9 extends, the two groups of first limit blocks 7 are again inserted into the first slot.

[0045] The movable module includes a mounting frame 13, a movable mold 14, a second forward and reverse screw 15, a second limit block 16, a second gear 17 and a connecting rod 18. The lower part of the movable frame 10 away from the pusher 9 is provided with a second slot, and the lower part of the second slot is provided with a second slide groove. The second forward and reverse screw 15 passes through the side wall of the second slide groove and is connected to the center of the second gear 17. The second limit block 16 is provided in two groups symmetrically arranged. The lower part of the second limit block 16 is inserted into the second slide groove and is threadedly connected to the second forward and reverse screw 15. The mounting frame 13 is L-shaped. The lower part of the mounting frame 13 is inserted into the second slot and is provided with a second card slot adapted to the upper part of the second limit block 16. The mounting frame 13 is close to the end of the first bracket 3 and is provided with four groups of connecting rods 18 connected to the movable mold 14.

[0046] The working principle of the mobile module is similar to that of the fixed module. An inverted L-shaped support plate 19 is symmetrically provided on the left and right sides of the second bracket 4. A second rack 20 adapted to the second gear 17 is provided below the support plate 19 near one end of the second bracket 4. A support groove slidably connected to the support plate 19 is provided in the middle part of the left and right sides of the mobile frame 10. When the propeller 9 is retracted, the second gear 17 moves toward the second rack 20 of the support plate 19. After the second gear 17 contacts and meshes with the second rack 20, the second gear 17 drives the second forward and reverse screw 15 to rotate, and the two sets of second limit The block 16 exits the second slot, and the mounting bracket 13 can be disassembled at this time. In this embodiment, when the second gear 17 contacts the second rack 20, the first rack 12 contacts the first gear 8, that is, the fixed mold 5 and the mounting bracket 13 that drives the movable mold 14 can be installed and disassembled synchronously. Since the distance between the two groups of molds is large during disassembly, the operating space is increased. When the corresponding mold is in a fully unlocked state, the equipment can be stopped and then manually disassembled. After the staff replaces the corresponding mold, the equipment is started again, and the pusher 9 is extended to complete the synchronous installation of the two groups of molds, which is highly efficient and safe.

[0047] In actual use, it is necessary to stably demold the material after injection molding. To this end, the mobile module also includes a demolding assembly, and the mobile module also includes a demolding assembly. The demolding assembly includes a first elastic member 35, a guide plate 21, a third gear 22, a shift block 23, a return spring 24, a demolding plate 25 and a demolding rod 26. The left and right sides of the mounting frame 13 are symmetrically provided with guide plates 21 arranged up and down. The upper part of the support plate 19 is arranged between the corresponding two groups of guide plates 21. The third gear 22 is also rotatably provided between the corresponding two groups of guide plates 21. The third gear 22 is symmetrically provided with an inverted L-shaped shift block 23 on the upper and lower sides. The mounting frame 13 is provided with a receiving groove adapted to the third gear 22 and the shift block 23. The reset spring 24 is sleeved on the connecting rod 18. A demolding plate 25 is also provided between the mounting frame 13 and the movable mold 14. The four groups The connecting rod 18 passes through the lifting plate 25, and the two ends of the return spring 24 are respectively connected to the lifting plate 25 and the movable mold 14. The lifting plate 25 is also provided with a lifting rod 26 that passes through the mold cavity of the movable mold 14. The mounting frame 13 is also provided with a driving groove on the left and right sides near one end of the second bracket 4. The two ends of the first elastic member 35 are respectively connected to the inner wall of the driving groove and the third rack 27. The third rack 27 is meshed with the third gear 22. The third rack 27 is further provided with a driving block with an inclined surface at the end away from the first elastic member 35. The support plate 19 is provided with a chamfered contact with the driving block. When the injection molding is completed, the pusher 9 drives the movable frame 10 to move backward. During the movement, the driving block contacts the chamfered contact of the support plate 19, squeezing the first elastic member 35. The third rack 27 drives the third gear 22 to rotate, thereby driving the shift blocks 23 on its upper and lower sides to rotate. When the shift block 23 rotates, it pushes the lifting plate 25. The lifting plate 25 is pushed by the shift block 23, squeezing the reset spring 24. The reset spring 24 contracts, and the lifting plate 25 drives the ejection rod 26 to move into the mold cavity to push out the material. At this time, the movable frame 10 has not entered the mold unlocking area. After the demoulding is completed, the pusher 9 continues to extend, and the reset spring 24 cooperates with the first elastic member 35 to reset the third gear 22. Then the movable mold 14 and the fixed mold 5 are closed and the injection molding is continued. In this process, the travel area of ​​the pusher 9 is the injection molding processing area.

[0048] In this embodiment, a material discharge trough is also provided on the workbench 1, and an inverted T-shaped guide block 28 is provided under the first rack 12 and the slide 11. A guide groove that passes through the material discharge trough and is compatible with the guide block 28 is provided on the workbench 1. Four groups of guide rods 29 are also provided between the first bracket 3 and the second bracket 4. The four groups of guide rods 29 pass through the movable frame 10. The first slide groove and the second slide groove are both arranged above the two groups of lower-end guide rods 29. The material discharge trough passes through from left to right, which is convenient for placing the loading frame. The guide block 28 ensures the stability of the movement of the slide 11 with the first rack 12, and the guide rod 29 ensures the stability of the movement of the movable frame 10.

[0049] During actual use, it was found that the exposed gears and racks are prone to accidentally biting the workers' clothes, and are affected by external foreign objects, resulting in unstable or even dangerous work. For this reason, the second bracket 4 is symmetrically provided with inverted L-shaped guard plates 30 on both sides near one end of the injection molding machine 2. The upper part of the guard plate 30 is provided with a first notch that fits the side wall of the support plate 19. The first bracket 3 and the second bracket 4 are flush on the left and right sides. The discharge chute is located below the two groups of guard plates 30, which does not affect the equipment discharge. The fixed mold 5 and the bottom wall of the fixed frame with the movable mold 14 are located above the guard plate 30, which does not affect the installation and disassembly of the corresponding mold.

[0050] In the injection molding processing area, it is necessary to ensure the stability of the first gear 8 and the second gear 17. To this end, the first gear 8 and the second gear 17 are both provided with a directional rod 31 at the same horizontal height on the side away from the center of the workbench 1. A limit member is provided on the lower part of the guard plate 30 close to the center of the workbench 1. The limit member includes a second elastic member 36 and a movable plate 32. Two groups of second elastic members 36 connected to the side walls of the guard plate 30 are provided on the movable plate 32. Guide holes adapted to the two groups of directional rods 31 are also provided on the movable plate 32. There is a gap between the movable plate 32 and the slide plate 11. A first push block 33 is provided on the side of the first rack 12 close to the second bracket 4. A second notch is also provided below the movable plate 32. A second push block 34 is provided on the slide plate 11. 3 and the second push block 34 are both provided with an inclined surface on the side close to the second bracket 4. In the injection molding processing area, the second push block 34 moves in the second notch, and the first push block 33 does not contact the movable plate 32. At this time, the second elastic member 36 is in a naturally extended state. When the corresponding mold needs to be disassembled, the pusher 9 contracts. At this time, the inclined surfaces of the first push block 33 and the second push block 34 contact and squeeze the movable plate 32, the second elastic member 36 contracts, and the directional rod 31 withdraws from the guide hole of the movable plate 32. Then the pusher 9 further contracts, and the first gear 8 and the first rack 12 will be engaged, and the second gear 17 and the second rack 20 will be engaged, avoiding the problem that the corresponding gears and racks cannot be stably engaged due to equipment vibration. It should be noted that after the demoulding is completed and the mold is unlocked, the third rack 27 no longer moves, and the mold is always in the demoulding state.

[0051] In this embodiment, the first elastic member 35 and the second elastic member 36 are both composed of a spring sleeved telescopic rod to ensure their operational stability.

[0052] During actual use, the four corners of the first limiting block 7 and the second limiting block 16 are all provided with chamfers to ensure the stability of the corresponding limiting block and the corresponding card slot.

[0053] In order to further ensure the stability of equipment assembly, centering grooves are provided in the middle part above the first slot and the second slot, and centering blocks 37 are provided on the movable frame 10 and the fixed mold 5 to be engaged with the corresponding centering grooves. The centering blocks 37 facilitate the centering of the corresponding mold and the corresponding bearing part of the equipment for easy use.
