Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0033] Please refer to Figures 1 - 6 , the present utility model provides a technical solution:
[0034] Embodiment 1:
[0035] A production mold for an automobile sunroof that is easy to demold, including a lower die 1 and an upper die 2. The upper die 2 is located on the top of the lower die 1. A forming groove 3 is opened on the top of the lower die 1, and a transmission groove 4 is opened inside the lower die 1. A demolding mechanism is arranged inside the transmission groove 4, which can demold the formed automobile sunroof;
[0036] One implementation manner of this Embodiment 1 is: The demolding mechanism includes two support plates 5 arranged inside the transmission groove 4. A plurality of ejector rods 6 are arranged on the top of the support plate 5. The top of the ejector rod 6 penetrates into the forming groove 3, and is fixedly connected with an ejector block 7;
[0037] A buffer mechanism for avoiding damage to the automobile sunroof is arranged at the bottom of the support plate 5.
[0038] The demolding mechanism further includes a motor 8 fixedly arranged on one side of the lower die 1. The output end of the motor 8 penetrates into the housing 13, and is fixedly connected with a worm 9. A worm gear 10 is meshed and connected to one side of the worm 9. A lead screw 11 is fixedly connected to the top of the worm gear 10. A moving block 12 is in transmission connection with the surface of the lead screw 11. The two sides of the moving block 12 are respectively fixedly connected with one side of the two support plates 5.
[0039] In this embodiment, considering that it is inconvenient to demold and take out the automotive skylight after molding, and it is easy to cause damage due to improper operation during the material taking process, which affects the molding effect of the mold. Therefore, by setting up a demolding mechanism, when the automotive skylight is extruded and formed, the upper mold 2 can be separated from the punching machine. Then, the motor 8 is started, and the motor 8 drives the worm 9 to rotate. The worm 9 drives the worm wheel 10 to rotate around the first bearing seat 16. The worm wheel 10 drives the lead screw 11 to rotate. During the rotation of the lead screw 11, it drives the moving block 12, so that the moving block 12 and the support plate 5 move upward along the trajectories of the dovetail guide rail 18 and the dovetail chute 19. The support plate 5 drives the ejector rod 6 and the ejector block 7 to move upward. Multiple ejector blocks 7 are in uniform contact with the bottom of the automotive skylight, and then the automotive skylight can be easily ejected from the inside of the molding groove 3, achieving the effect of facilitating demolding.
[0040] It solves the problem that considering it is inconvenient to demold and take out the automotive skylight after molding, and it is easy to cause damage due to improper operation during the material taking process, which affects the molding effect of the mold.
[0041] Preferably, first bearing seats 16 are arranged at the tops of the lead screw 11 and the worm wheel 10, and they are rotationally connected to the inner wall of the transmission groove 4 through the first bearing seats 16. One end of the worm 9 is provided with a second bearing seat 17, and it is rotationally connected to the inner wall of the transmission groove 4 through the second bearing seat 17.
[0042] In this embodiment, by setting the first bearing seat 16 and the second bearing seat 17, it can play a supporting role for the worm 9 and the worm wheel 10, making the two always keep in meshing state, and at the same time improving the smoothness and stability of their rotation.
[0043] Preferably, dovetail guide rails 18 are fixedly connected to both sides of the transmission groove 4, and dovetail chutes 19 adapted to the dovetail guide rails 18 are formed on one side of the support plate 5.
[0044] In this embodiment, by setting the dovetail guide rail 18 and the dovetail chute 19, it can limit the movement trajectories of mechanisms such as the support plate 5. When the lead screw 11 rotates to drive the moving block 12 and the support plate 5, structures such as the support plate 5 can only move downward or upward along the dovetail guide rail 18 and the dovetail chute 19.
[0045] Preferably, the motor 8 is a servo motor 8 and can perform forward and reverse rotations.
[0046] In this embodiment, by selecting the model of the motor 8 as a servo motor 8, it can ensure the stability of the motor 8 during low-speed rotation, and thus improve the demolding effect.
[0047] Embodiment Two:
[0048] Based on the first embodiment, in this embodiment, the demolding mechanism can eject the automotive skylight by moving the ejector rod 6 and the ejector block 7 upward to achieve the demolding effect. However, considering that the surface of the automotive skylight is not flat, this rigid contact may cause damage to the automotive skylight. In this application, the buffer mechanism includes a housing 13 fixedly connected to the bottom of the support plate 5. The number of the housings 13 is the same as that of the ejector rods 6. A spring 14 is fixedly connected inside the housing 13, and a buffer block 15 is fixedly connected to the top of the spring 14;
[0049] The bottom of the ejector rod 6 penetrates into the interior of the housing 13 and is fixedly connected to the top of the buffer block 15.
[0050] In this embodiment, considering that the surface of the automotive skylight is not flat, this rigid contact may cause damage to the automotive skylight. Therefore, by providing a buffer mechanism, when the ejector block 7 contacts the automotive skylight, the spring 14 will be compressed and buffered under the influence of extrusion until all the ejector blocks 7 are in contact with the surface of the automotive skylight. At this time, the automotive skylight is evenly stressed, and it can be easily demolded without causing damage to the automotive skylight.
[0051] Working principle: When the automotive skylight is extruded, the upper mold 2 is separated by the stamping machine. Then, the motor 8 is started. The motor 8 drives the worm 9 to rotate. The worm 9 drives the worm wheel 10 to rotate around the first bearing seat 16. The worm wheel 10 drives the lead screw 11 to rotate. During the rotation of the lead screw 11, the moving block 12 is driven, so that the moving block 12 and the support plate 5 move upward along the tracks of the dovetail guide 18 and the dovetail chute 19. The support plate 5 drives the ejector rod 6 and the ejector block 7 to move upward. When the ejector block 7 contacts the automotive skylight, the spring 14 will be compressed and buffered under the influence of extrusion until all the ejector blocks 7 are in contact with the surface of the automotive skylight, and then the automotive skylight can be easily ejected from the forming groove 3 to achieve the effect of facilitating demolding.
[0052] It should be noted that the motor 8 is a device or equipment existing in the prior art, or a device or equipment that can be realized by the prior art. And the specific composition and principle of the power supply of the motor 8 are clear to those skilled in the art, so it will not be described in detail here.
[0053] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
