Abstract
Description
Technical Field
[0001] This application relates to the technical field of molds, and in particular to an in-mold lifting and positioning device. Background Technology
[0002] In sheet metal stamping production in industries such as automobiles, home appliances, and new energy battery packs, in-mold material lifting and positioning technology is crucial to product quality and production efficiency. Currently, there are two main types of in-mold material lifting and positioning: "L"-shaped external positioning and "T"-shaped positioning.
[0003] The "L"-shaped external positioning is suitable for positioning flat products, but when encountering parts with large differences in surface height, the parts will tilt, resulting in unstable product dimensions after stamping.
[0004] While the "T" type positioning system combines positioning and lifting functions, and the middle section can adjust the height difference, it suffers from inaccurate positioning. Moreover, its spring is subjected to oblique force at a variable angle, is not adjustable, has a short lifespan, is difficult to replace, and poses a safety hazard if it breaks.
[0005] When machining parts with special structures, neither of the existing positioning methods can keep the sheet material parallel before forming, making it difficult to guarantee the stability of the part. Currently, most processes solve this problem by trimming or increasing the edge tolerance after forming. The former increases the number of processes and wastes resources, while the latter reduces the part's fit and affects product quality. Utility Model Content
[0006] In order to reduce the waste of process resources and improve the versatility of parts when processing parts with special structures, this application provides an in-mold lifting and positioning device.
[0007] This application provides an in-mold material lifting and positioning device, employing the following technical solution: The main body of the mechanism includes a base, a vertical plate fixedly connected to the upper surface of the base, a first sliding groove on one side of the vertical plate, a first slider slidably connected within the first sliding groove, a driving block fixedly connected to one side of the first slider, an inclined surface on the upper surface of the driving block, a second sliding groove on the other side of the vertical plate, a second slider slidably connected within the second sliding groove, a lifting plate fixedly connected to one side of the second slider, one end of the lifting plate fixedly connected to one side of the driving block, a fixing plate fixedly connected to one side of the vertical plate, a threaded hole on one side of the fixing plate, an adjusting screw threadedly connected within the threaded hole, a pressure plate rotatably connected to one end of the adjusting screw, and a spring disposed between the pressure plate and the driving block. The distance is adjusted by the adjusting screw to better adapt to the material plate.
[0008] Optionally, a groove is provided on one side of the drive block, and a wire spring is provided in the groove. One end of the wire spring is fixedly connected to the inner wall of the groove, and the other end of the wire spring is fixedly connected to one side of the upright plate.
[0009] Optionally, both the drive block and the pressure plate have spring holes inside, and the spring is disposed within the spring hole. The spring hole facilitates the placement of the spring.
[0010] Optionally, a knob is fixedly connected to the other end of the adjusting screw, and the outer surface of the knob is provided with anti-slip texture. The anti-slip texture facilitates the rotation of the knob.
[0011] Optionally, the upper surface of the base is provided with four mounting holes, which are arranged in a rectangular pattern.
[0012] Optionally, the upper surface of the lifting plate is provided with an anti-slip pad, and the anti-slip pad is made of rubber.

[0022] The following is in conjunction with the appendix Figure 1-5 The accompanying drawings provide a further detailed description of this application. The technical solutions in the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.
[0023] This application discloses an in-mold material lifting and positioning device. For example... Figure 1 As shown, an in-mold material lifting and positioning device includes a main body, which includes a base 1. A vertical plate 2 is fixedly connected to the upper surface of the base 1. A first sliding groove 3 is opened on one side of the vertical plate 2. A first slider 4 is slidably connected in the first sliding groove 3. A driving block 5 is fixedly connected to one side of the first slider 4. An inclined surface 6 is opened on the upper surface of the driving block 5. A second sliding groove 7 is opened on the other side of the vertical plate 2. A second slider 8 is slidably connected in the second sliding groove 7. A lifting plate 9 is fixedly connected to one side of the second slider 8. One end of the lifting plate 9 is fixedly connected to one side of the driving block 5. A fixing plate 10 is fixedly connected to one side of the vertical plate 2. A threaded hole 11 is opened on one side of the fixing plate 10. An adjusting screw 12 is threadedly connected in the threaded hole 11. A pressure plate 13 is rotatably connected to one end of the adjusting screw 12. A spring 14 is provided between the pressure plate 13 and the driving block 5.
[0024] Please see Figure 4 A groove is provided on one side of the drive block 5, and a wire spring is provided in the groove. One end of the wire spring is fixedly connected to the inner wall of the groove, and the other end of the wire spring is fixedly connected to one side of the upright plate 2. The wire spring 16 can enable the drive block 5 to automatically reset after being subjected to external force.
[0025] Please see Figure 5 Both the drive block 5 and the pressure plate 13 have spring holes 15 inside, and the spring 14 is set in the spring hole 15. The setting of the spring hole 15 can ensure that the spring 14 has compression space in various states, avoid the spring 14 from breaking, and improve the safety performance of the device.
[0026] Please see Figure 1 The other end of the adjusting screw 12 is fixedly connected to a knob. The outer surface of the knob is provided with anti-slip texture. The knob makes it convenient for the operator to rotate the adjusting screw 12 to adjust the compression of the spring 14.
[0027] Please see Figure 1 The upper surface of the base 1 has four mounting holes arranged in a rectangular pattern, which facilitates the installation and fixation of the device.
[0028] The upper surface of the lifting plate 9 is provided with an anti-slip pad. The anti-slip pad is made of rubber. The anti-slip pad can increase the friction between the lifting plate 9 and the material sheet, and prevent the material sheet from sliding during the lifting process.
[0029] The implementation principle of the in-mold lifting and positioning device in this embodiment is as follows: In use, the main body of the mechanism is first installed in the lower mold at the position where material needs to be lifted, according to the characteristics of the part. During the closing process of the upper mold, the pressure plate first presses down on the material sheet, and then the upper mold punch contacts the inclined surface 6 of the lifting drive block 5. After the upper mold punch contacts the inclined surface 6 of the drive block 5, the drive block 5 retracts to a state that does not interfere with the product, allowing the material sheet to maintain a stable downward forming flow. Simultaneously, the operator can adjust the adjusting screw 12 by rotating the knob according to the actual required force, thereby adjusting the compression of the spring 14 and thus adjusting the ejection force of the wire spring. The spring holes 15 inside the drive block 5 and the pressure plate 13 ensure that the spring 14 has compression space in any state, improving the safety performance of the mechanism and ensuring a safe and stable production process.
[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
