Description

Technical Field

[0001] This utility model relates to the field of automotive mold technology, specifically to a stamping and fixing device for automotive mold production. Background Technology

[0002] Stamping fixing devices for automotive mold production are specifically designed to stabilize modular molds, ensuring that the molds remain highly stable during stamping operations. This effectively prevents mold loosening and avoids adverse consequences such as stamping deviations and product scrap caused by mold loosening, thus ensuring smooth stamping production and product quality.

[0003] For example, Chinese Patent Application No. 202120962543.7 discloses a stamping fixing device for automobile mold production, including a base, a support plate, a mounting plate, a fixing plate, a first lifting device, an upper mold, two connecting plates, four sliding plates, a lower mold, a second lifting device, and four first springs. The base has a mounting groove and four sliding grooves; each sliding groove has multiple locking slots on its inner wall; the lower mold is installed in the mounting groove; the support plate connects the fixing plate and the base; the first lifting device connects to the fixing plate; the mounting plate connects to the first lifting device and the second lifting device; the second lifting device connects to the upper mold; both ends of each first spring are connected to the bottom surface of each sliding groove and each sliding plate; each sliding plate has multiple locking blocks; two sliding plates located on the same side of the mounting groove are connected to the same connecting plate. This utility model has a simple structure and is easy to use, and can fix stamping plates of different sizes, improving the practicality of the stamping device.

[0004] In the actual use of automotive molds, multiple screws are typically used to install and fix the combined mold. However, after multiple and prolonged stamping operations, the fastening force between the screws and the mold gradually weakens due to continuous mechanical vibration and stress, making the mold prone to loosening. Once the mold loosens, it will cause the stamped parts to have out-of-tolerance dimensional accuracy, surface quality defects, and may even lead to serious consequences such as mold damage and production interruption.

[0005] Therefore, it is necessary to redesign and modify the stamping fixing device used in automobile mold production to effectively prevent the mold from loosening. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, the present invention provides a stamping fixing device for automobile mold production, including a mold 1. A fixing mechanism is provided on the upper side of the mold 1. The fixing mechanism includes a mold 2 installed on the lower side of the mold 1. Both the mold 1 and the mold 2 have multiple through holes 3 on their upper sides. A screw 4 is threaded to the inner wall of the through hole 3. A locking block 5 is engaged on the upper side of the screw 4. A worm gear 6 is fixedly connected to the upper side of the locking block 5. A worm 7 is engaged on the outer side of the worm gear 6. Synchronous lifting mechanisms are provided on the left and right sides of the upper side of the mold 1.

[0023] refer to Figure 3The synchronous lifting mechanism includes a rotating rod 8 that is movably connected to the inner wall of the worm gear 6 via a bearing. A lifting frame 9 is fixedly connected to the upper end of the rotating rod 8. The inner wall of the lifting frame 9 is movably connected to the surface of the worm gear 7 via a bearing. A limit frame 10 is slidably connected to the surface of the lifting frame 9. The inner side of the limit frame 10 is fixedly connected to the left and right sides of the mold 1. A control mechanism is provided on the upper side of the mold 1.

[0024] As a technical optimization of this utility model, by setting a synchronous lifting mechanism, the worm gear 6 can drive the lifting frame 9 to rise and fall synchronously through the rotating rod 8 when it rotates. The limit frame 10 ensures the linearity and stability of the movement of the lifting frame 9, so as to realize the synchronous and stable lifting of the screw 4 and facilitate the quick fixation of the mold.

[0025] refer to Figure 4 The control mechanism includes a transmission rod 11 slidably connected to the inner wall of the limiting frame 10. The end of the transmission rod 11 near the worm gear 6 and the surface of the worm 7 are both fixedly connected to bevel gears 12, which mesh with each other. The surface of the transmission rod 11 is movably connected to a synchronous plate 13 via a bearing. The front and rear sides of the synchronous plate 13 are fixedly connected to the inner side of the lifting frame 9, and the inner side of the synchronous plate 13 is slidably connected to the left and right sides of the limiting frame 10. The end of the transmission rod 11 away from the worm 7 is fixedly connected to a knob 14, and a diamond-shaped block 15 is fixedly connected to the outer side of the knob 14 for easy turning with a wrench.

[0026] As a technical optimization of this utility model, by setting up a control mechanism, the operation of the entire fixing and lifting system is made more convenient and faster. The design of the rhombus block 15 and the slot 17 facilitates operation with a wrench and improves work efficiency.

[0027] refer to Figure 3 The left and right sides of the upper side of the mold 1 are fixedly connected to the reinforcing blocks 16, and the lower side of the reinforcing blocks 16 is fixedly connected to the surface of the limiting frame 10.

[0028] As a technical optimization of this utility model, by setting the reinforcing block 16, the connection strength between the mold 1 and the limiting frame 10 is increased, making the whole device more stable during the stamping process, reducing structural loosening and errors caused by vibration, and improving the stamping quality.

[0029] refer to Figure 2 The surface of the rhombus block 15 is provided with a slot 17, which is used to facilitate the turning of the wrench.

[0030] As a technical optimization of this utility model, by setting the slot 17, it is convenient for the wrench to turn. Compared with the ordinary knob 14, this design increases the friction and force application point during operation, and the operator can turn the knob 14 more easily. Especially when a large torque is required, it can improve the convenience and efficiency of operation.

[0031] refer to Figure 2 A connecting plate 18 is fixedly connected to the surface of the lifting frame 9. The connecting plate 18 is used to increase the stability of the lifting frame 9 when moving up and down.

[0032] As a technical optimization of this utility model, by setting the connecting plate 18, the stability of the lifting frame 9 moving up and down is increased. During the lifting process of the lifting frame 9, the accuracy of mold fixing and the smoothness of the stamping process are ensured, and the service life of the device is extended.

[0033] The working principle and usage process of this utility model are as follows: In use, a wrench is inserted into the slot 17 of the diamond-shaped block 15, and the knob 14 is rotated, causing the transmission rod 11 to rotate. The bevel gear 12 on the transmission rod 11 rotates accordingly. Because it meshes with the bevel gear 12 on the surface of the worm 7, it drives the worm 7 to rotate. The worm 7 meshes with the worm wheel 6, causing the worm wheel 6 to drive the locking block 5 to rotate. The locking block 5 engages with the screw 4. The screw 4, due to its threaded connection within the through hole 3, can move up and down and fix the second mold 2. Simultaneously, the rotating rod 8, connected to the inner wall of the worm wheel 6 via a bearing, rotates with the worm wheel 6, driving the upper fixed lifting frame 9. The lifting frame 9 slides within the limit frame 10 to achieve up and down movement. The synchronous plate 13 moves with the lifting frame 9, and the connecting plate 18 further enhances the stability of the lifting frame 9's movement. Finally, through the lifting of the lifting frame 9 and the movement of the screw 4, the fixing of the first mold 1 and the second mold 2 is completed (the structure of the worm wheel 6 and worm 7 prevents the screw 4 from loosening). It avoids the loosening of the mold caused by long-term stamping of automotive molds, making it easy to use.

[0034] In summary, when this utility model is used, under the action of the fixing mechanism, the synchronous lifting mechanism and the control mechanism, it can stably fix the automobile mold, avoiding the loosening of the mold caused by long-term stamping, thus giving it the advantage of being easy to use.
