[0027] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0028] Reference Figure 1-7 This utility model discloses a mold for an electronic calculator casing that facilitates demolding. It includes a lower connecting plate 1, with multiple guide rods 2 fixedly connected to the upper surface of the lower connecting plate 1. An upper connecting plate 3 is slidably connected to the outer surface of each guide rod 2. An anti-detachment block 4 is fixedly connected to the end of each guide rod 2 away from the lower connecting plate 1, and the outer surface of the anti-detachment block 4 contacts the upper connecting plate 3. Both the lower connecting plate 1 and the upper connecting plate 3 have two T-slots 5. T-blocks 6 are slidably connected to the inner surfaces of the four T-slots 5. Two T-blocks 6 are fixedly connected to the same lower sliding plate 7, whose lower surface contacts the lower connecting plate 1. The other two T-blocks 6 are fixedly connected to the same upper sliding plate 8, whose upper surface contacts the upper connecting plate 3. Under the action of the T-slots 5, the T-blocks 6, lower sliding plate 7, and upper sliding plate 8 can move smoothly while preventing the T-blocks 6 from moving. The slide plate 7 and upper slide plate 8 are detached from the lower connecting plate 1 and upper connecting plate 3. The upper surface of the lower slide plate 7 is fixedly connected to the support frame 9. The support frame 9 is fixedly connected to the cylinder 10. The output end of the cylinder 10 is fixedly connected to the movable plate 11. The upper surface of the movable plate 11 is fixedly connected to multiple push rods 12. The upper surface of the support frame 9 is fixedly connected to the lower mold 14. The lower surface of the upper slide plate 8 is fixedly connected to the upper mold 15. The support frame 9 is fixedly connected to two limit blocks 13. The outer surfaces of the two limit blocks 13 are slidably connected to the movable plate 11. The outer surfaces of the push rods 12 are slidably connected to the support frame 9. The outer surfaces of the push rods 12 are slidably connected to the lower mold 14. The lower connecting plate 1 and the upper connecting plate 3 are both fixedly connected to two docking blocks 22. Each of the four docking blocks 22 has two docking holes 23. Through the reserved docking holes 23, the entire structure can be connected to the stamping device.
[0029] Two connecting blocks 16 are fixedly connected to both the lower connecting plate 1 and the upper connecting plate 3. Two connecting shafts 17 are fixedly connected to each of the four connecting blocks 16. The same movable block 18 is rotatably connected to the two corresponding connecting shafts 17. Two threaded rods 20 are fixedly connected to both the lower sliding plate 7 and the upper sliding plate 8. Nuts 21 are threadedly connected to the outer surfaces of the four threaded rods 20. The inner surface of the movable block 18 is in contact with the connecting block 16, and the side surface of the nut 21 is in contact with the movable block 18. A connecting groove 19 is provided on the movable block 18. The connecting groove 19 can prevent the connecting groove 19 from affecting the rotation of the movable block 18.
[0030] Working principle: Through the pre-drilled docking hole 23 on the docking block 22, the lower connecting plate 1 can be connected to the processing table of the stamping equipment, and the upper connecting plate 3 can also be connected to the stamping mechanism of the stamping equipment. When the stamping mechanism drives the upper connecting plate 3, T-block 6 and upper mold 15 to press down to process the electronic calculator shell, the cylinder 10 on the support frame 9 is activated, causing the output end of the cylinder 10 to extend and move, thereby driving the movable plate 11 and the ejector rod 12 to move. In turn, the moving ejector rod 12 ejects the stamped electronic calculator shell workpiece from the lower mold 14, achieving the demolding effect. It is simple and quick. After unscrewing the nut 21 from the threaded rod 20 with a wrench or other tools, the fixing of the movable block 18, lower slide plate 7, upper slide plate 8 and other structures can be released. Then, the movable block 18 is flipped, so that the movable block 18 and the connecting groove 19 rotate around the connecting shaft 17 on the connecting block 16 as the central axis. After flipping 18 to the other side, pull the lower slide plate 7 and the upper slide plate 8 respectively, thereby moving the lower slide plate 7 and the upper slide plate 8, and thus moving the lower mold 14 and the upper mold 15. This allows the lower mold 14 and the upper mold 15 to be moved away from the stamping device, making it easier for maintenance personnel to carry out maintenance work on the lower mold 14 and the upper mold 15. After the maintenance of the lower mold 14 and the upper mold 15 is completed, push the lower slide plate 7 and the upper slide plate 8 respectively, thereby moving the lower slide plate 7, the upper slide plate 8 and the structures on the lower slide plate 7 and the upper slide plate 8 to reset. After the structures such as the lower mold 14 and the upper mold 15 are reset, flip the movable block 18 in the opposite direction. At this time, the movable block 18 is flipped in the opposite direction with the connecting shaft 17 as the central axis. After the movable block 18 is reset, screw the nut 21 back onto the threaded rod 20 and tighten it. This not only fixes the structures such as the movable block 18, but also fixes the structures on the lower slide plate 7 and the upper slide plate 8.
[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
