Description

Technical Field

[0001] This utility model relates to the field of mold component technology, specifically a demolding mechanism for a plastic clamp mold. Background Technology

[0002] In the injection molding process of plastic clips (such as snap clips and elastic clips used in office, electronic and household products), the design of the mold demolding mechanism is crucial because plastic clips often have complex geometric structures, such as snaps, barbs, elastic arms, slender parts, etc. These structures can easily lead to demolding difficulties or product damage.

[0003] First, if the mold is not securely connected to the mechanical components, it may cause inaccurate positioning, resulting in defective products, which in turn leads to mold vibration, increased wear, and reduced lifespan.

[0004] Secondly, the mold is fixed as a "dead mold" and cannot flexibly change the plastic clip model. Each type of plastic clip requires a separate complete mold, which is costly. Utility Model Content

[0029] 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.

[0030] Example 1:

[0031] Please see Figures 1-7A demolding mechanism for a plastic clamping mold includes a main body 1, an installation mechanism, and a mating mechanism. The installation mechanism includes a mold 2, a first locking block 3, a first rotating rod 4, a reset plate 5, and a positioning rod 6. The mold 2 is installed on the main body 1 and matingly connected to it. The first locking block 3 is installed in the mold 2 and slidably connected to it. The first rotating rod 4 is installed in the mold 2 and rotatably connected to both the mold 2 and the first locking block 3. The reset plate 5 is installed inside the mold 2 and rotatably connected to it. The positioning rod 6 is installed on the first rotating rod 4. The mechanism includes a drive frame 7, a discharge component 8, a first spring 9, a second rotating rod 10, and a second locking block 11. The drive frame 7 is installed inside the main body 1 and is slidably connected to the main body 1. The discharge component 8 is installed on the drive frame 7 and is connected to the drive frame 7. The first spring 9 is fixedly installed in the discharge component 8 and its other end is fixedly connected to the second locking block 11. The second locking block 11 is installed in the discharge component 8 and is slidably connected to the discharge component 8. The second rotating rod 10 is installed in the discharge component 8 and is rotatably connected to the discharge component 8.

[0032] In this embodiment, the installation mechanism includes a mold 2, a first locking block 3, a first rotating rod 4, a reset plate 5, and a positioning rod 6. In use, different molds 2 need to be replaced according to different plastic parts. The mold 2 can then be installed onto the main body 1. During installation, the mold 2 engages with the limiting rod 12 on the main body 1, and the fitting frame 15 on the mold 2 engages with the mounting frame 13 on the main body 1. The positioning rod 6 can then be pressed, causing the drive rod 18 to rotate the first rotating rod 4 within the fitting frame 15. After pressing, the drive rod 18 directly stretches the second spring 25, causing the insertion rod 17 on the positioning rod 6 to disengage directly from the positioning hole 16 on the fitting frame 15. When the positioning rod 6 rotates, the reset plate 5, which is fixedly connected to one end of the second spring 25, also rotates within the fitting frame 15. The first locking block 3, due to its threaded engagement with the first rotating rod 4, engages with the first locking hole 14 on the mounting frame 13 under the action of the first rotating rod 4, thus completing the installation of the mold 2 onto the main body 1.

[0033] In this embodiment, the mating mechanism includes a drive frame 7, an unloading component 8, a first spring 9, a second rotating rod 10, and a second locking block 11. During use, when a new mold 2 is used, its corresponding demolding components need to be changed. At this time, the drive rod 18 is connected via a hydraulic cylinder, causing the drive frame 7 to be located at the bottom of the main body 1. Then, the unloading component 8, corresponding to the mold 2, is installed on the drive frame 7. The unloading component 8 is installed into the mounting slot 21 on the drive frame 7. During the installation of the unloading component 8, the second rotating rod 10 can be directly rotated, causing the second rotating rod 10 to begin winding with the connecting rope 24, thus causing the second locking block 11 to be pressed against the first spring 9, thereby facilitating unloading. The material slides into part 8. After it is fully inserted into part 8, the second rotating rod 10 is released. Under the action of the compressed first spring 9, the second locking block 11 enters the second locking hole 20 of the drive frame 7, thus completing the installation of part 8 on the drive frame 7. Then the closing cover 19 can be installed on the main body 1. When in use, the drive rod 18 is pushed in a short stroke, so that the unloading rod 22 slides in the unloading hole 23. At the same time, the rod head of the unloading rod 22 is also kept horizontal with the groove inside the mold 2. When unloading is required, the push of the drive rod 18 is increased, so that the unloading rod 22 can slide completely in the unloading hole 23, thereby causing the plastic clamp to disengage from the mold 2.

[0034] Example 2:

[0035] In summary, during use, the first step is to replace the mold 2 with a different one depending on the plastic part. The mold 2 can then be installed onto the main body 1. During installation, the mold 2 engages with the limiting rod 12 on the main body 1, and the fitting frame 15 on the mold 2 engages with the mounting frame 13 on the main body 1. At this point, the positioning rod 6 can be pressed directly, causing the drive rod 18 to rotate the first rotating rod 4 within the fitting frame 15. After pressing, the drive rod 18 directly stretches the second spring 25, causing the insertion rod 17 on the positioning rod 6 to directly... The positioning hole 16 on the fitting frame 15 is disengaged, and when the positioning rod 6 rotates, the reset plate 5, which is fixedly connected to one end of the second spring 25, also rotates in the fitting frame 15. Due to the thread engagement between the first locking block 3 and the first rotating rod 4, the locking block engages with the first locking hole 14 on the mounting frame 13 under the action of the first rotating rod 4, completing the installation of the mold 2 on the main body 1. When a new mold 2 is replaced, its corresponding demolding components need to be changed. At this time, the drive rod 18 is connected by a hydraulic cylinder, so that the drive frame 7 is located at the bottom of the main body 1. Then, the unloading component 8 corresponding to the mold 2 is installed on the drive frame 7. At this time, the unloading component 8 is installed in the mounting groove 21 on the drive frame 7. When the unloading component 8 is installed, the second rotating rod 10 can be rotated directly, so that the second rotating rod 10 and the connecting rope 24 begin to wrap around, causing the second locking block 11 to be pressed against the first spring 9, so that it can slide in the unloading component 8. When it is fully inserted into the unloading component 8, the second rotating rod 10 is released. Under the action of the compressed first spring 9, the second locking block 11 is released. Block 11 enters the second slot 20 of the drive frame 7, thereby completing the installation of the unloading part 8 on the drive frame 7. Then, the closing cover 19 can be installed on the main body 1. When in use, the drive rod 18 is pushed in a short stroke, so that the unloading rod 22 is slidably connected with the unloading hole 23, and the rod head of the unloading rod 22 is also kept horizontal with the groove inside the mold 2. When unloading is required, the push of the drive rod 18 is increased, so that the unloading rod 22 can slide completely in the unloading hole 23, thereby causing the plastic clamp to disengage from the mold 2.

For all the fixed connections mentioned above, welding is preferred.
