Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an anti-reverse structure for a hydraulic cylinder slider in an injection mold. Background Technology

[0002] The anti-reverse structure of the hydraulic cylinder slider in injection molds mainly prevents the slider from retreating during the injection process through mechanical limiting and wedge-shaped matching, ensuring mold stability and product yield. It is suitable for injection molds that require high-precision slider positioning, and is especially suitable for the production of complex-shaped products, such as electronic product casings and precision mechanical parts.

[0003] Chinese Utility Model Patent CN215703795U discloses a small hydraulic cylinder slider anti-retraction mechanism for injection molds, relating to the technical field of injection molds. It includes a slider insert and a locking assembly for locking the slider insert. The hydraulic cylinder drives the shovel and locking slider to move for initial locking. The locking block assembly further locks and releases the shovel and locking slider during mold opening and closing, respectively. This effectively prevents the core-pulling slider from retracting due to excessive injection pressure during injection molding, ensuring product quality. Furthermore, this utility model has a simple structure and small overall size. Compared to mechanical slider core-pulling methods, it eliminates the need for additional templates, effectively preventing the need for larger injection molding machines due to increased mold thickness, saving production costs and improving enterprise economic efficiency.

[0026] 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.

[0027] Example: Please refer to Figures 1-6 The existing anti-retraction structure of the hydraulic cylinder slider in injection molds is not easy to simplify to save costs during production, and the anti-retraction structure requires regular maintenance. It is not convenient to set up a detachable structure for easy maintenance. In order to solve this technical problem, this embodiment discloses the following technical content.

[0028] A hydraulic cylinder slider anti-retraction structure for injection molds is provided. The upper surface of the fixed mold body 1 has a first placement groove 2 at the left end, and the slider body 3 is slidably connected inside the first placement groove 2. The lower surface of the slider body 3 is fixedly connected to a connecting protrusion 4. The bottom of the fixed mold body 1 is provided with a hydraulic cylinder slider mechanism. The hydraulic cylinder slider mechanism is composed of a shell 5, a drive hydraulic cylinder 6, a connecting plate 7, a shovel body 8, a connecting groove 9, and a third placement groove 11. The four corners of the left end of the shell 5 are fixedly connected to the fixed mold body 1 by several stabilizing bolts. The drive hydraulic cylinder 6 is provided inside the shell 5, and the output end of the drive hydraulic cylinder 6 is fixedly connected to the connecting plate 7. The connecting plate 7 is fixedly connected to the shovel body 8 at equal angles by several stabilizing bolts. The upper surface of the left end of the shovel body 8 has a connecting groove 9, and the connecting groove 9 is slidably connected to the connecting protrusion 4 at the bottom of the slider body 3. The lower surface of the shovel body 8 has a third placement groove 11 at the right end.

[0029] A second storage groove 10 is provided at the bottom right side of the fixed mold body 1. The shovel body 8 is slidably connected to the inside of the second storage groove 10. A fourth storage groove 12 is provided at the right end of the middle of the lower surface of the fixed mold body 1. An automatic telescopic rod 13 is provided at the bottom of the inside of the fourth storage groove 12. A square locking block 14 is fixedly connected to the output end of the automatic telescopic rod 13. The square locking block 14 is engaged with the third storage groove 11. The automatic telescopic rod 13 is fixedly connected to the middle of the upper surface of the connecting base plate 15. The four corners of the connecting base plate 15 are fixedly connected to the fixed mold body 1 by stabilizing bolts.

[0030] When using the anti-retraction structure of the injection mold cylinder slider, the drive cylinder 6 is activated. The output end of the drive cylinder 6 carries the shovel body 8 and slides it in the second placement groove 10 opened on the fixed mold body 1. Since the connecting protrusion 4 fixedly connected to the bottom of the slider body 3 is slidably connected in the connecting groove 9 opened on the inclined surface of the left side of the shovel body 8, when the shovel body 8 is moved to the left by the output end of the drive cylinder 6, the slider body 3 is pushed upward by the inclined surface on the left side of the shovel body 8. The connecting protrusion 4 and the connecting groove 9 are set to prevent the shovel body 8 from separating from the slider body 3. The slider body 3 slides in the first placement groove 2. When the shovel body 8 moves to the leftmost end, the slider body 3 will slide upward. After the block body 3 is lifted, injection molding can begin. At this time, the shovel body 8 needs to be fixed to the left end of the second storage slot 10. The automatic telescopic rod 13 is activated, and the output end of the automatic telescopic rod 13 moves the square locking block 14 upward, so that the square locking block 14 engages in the third storage slot 11 opened on the bottom surface of the shovel body 8, preventing the shovel body 8 from moving under pressure. After injection molding is completed, the automatic telescopic rod 13 is activated first, and the output end of the automatic telescopic rod 13 moves the square locking block 14 downward. After the square locking block 14 disengages from the third storage slot 11, the drive cylinder 6 can be activated, so that the output end of the drive cylinder 6 moves the shovel body 8 to the right, causing the slider body 3 to move downward.

[0031] The hydraulic cylinder slider and anti-retraction structure require regular maintenance. The drive cylinder 6 is located inside the outer shell 5, which is fixedly connected to the fixed mold body 1 by bolts. The output end of the drive cylinder 6 is fixedly connected to the shovel body 8 by the connecting plate 7 and the stabilizing bolts on the connecting plate 7. By removing the stabilizing bolts on the outer shell 5, the outer shell 5 can be removed from the fixed mold body 1, and the drive cylinder 6 and the shovel body 8 can be taken out from the second storage slot 10. By removing the stabilizing bolts on the connecting plate 7, the drive cylinder 6 can be separated from the shovel body 8. The automatic telescopic rod 13 and the square locking block 14 require regular maintenance. At this time, the stabilizing bolts on the connecting base plate 15 are removed, and the connecting base plate 15, the automatic telescopic rod 13, and the square locking block 14 are taken out from the fourth storage slot 12 at the same time. The automatic telescopic rod 13 and the square locking block 14 are maintained. After the maintenance is completed, the parts are fixed to the fixed mold body 1 again with bolts.
