Description

Technical Field

[0001] This utility model relates to the field of gate removal technology for injection molded products, and in particular to a gate removal device for injection molded products. Background Technology

[0002] Injection molding produces various plastic products by injecting molten plastic into a mold cavity using an injection molding machine, followed by cooling and solidification. These range from small toy parts and electronic casings to large automotive components. The gate, located in the mold, connects the runner to the cavity. Plastic residue can form sprues at this point. If these sprues are not removed, they not only affect the product's appearance but can also cause assembly problems, scratches during use, and other issues due to their protruding parts. Therefore, gate removal equipment is needed to efficiently and accurately remove these excess parts, ensuring product quality and smooth subsequent use.

[0003] Most gate removal processes typically involve placing the object requiring gate removal on a corresponding mold with openings. These openings correspond to the object itself. An ultrasonic vibrator then transmits vibrational energy to the gate connection point through high-frequency vibration. The shearing force generated by the vibration separates the gate waste from the product. The separated product falls out of the mold openings due to its own weight, while the dislodged gate waste, due to its dispersed location, mostly falls directly onto the mold, requiring manual cleaning. This increases the amount of repetitive labor and labor intensity, reducing overall production efficiency.

[0004] Therefore, it is necessary to provide a new gate removal device for injection molded products to solve the above-mentioned technical problems. Utility Model Content

The front end of the threaded block 10 is fixedly connected to the side of the sliding block 6 away from the load plate 7. A drive motor 11 is installed at the top of the support plate 5. The drive end of the drive motor 11 is fixedly connected to the top axis of the threaded rod 9. Mold 12 is inserted into the inner wall of the top of the through hole 2. Assembly plates 13 are fixedly connected to the top of both sides of mold 12. The outer sides of the two assembly plates 13 are inserted into the inner wall of the top left side of the working box 1. Bolts 14 are inserted into the inner wall of the assembly plates 13. The outer bottom end of the bolts 14 is threadedly connected to the inner wall of the top left side of the working box 1. A feeding plate 15 is fixedly connected to the left side of the working box 1. A guide assembly is installed on the top left side of the working box 1. A push plate 18 is slidably connected to the outside of the guide assembly. The guide assembly includes four fixed blocks 16. The bottom ends of the multiple fixed blocks 16 are fixedly connected to the top left side of the working box 1. A guide rod 17 is fixedly connected to the adjacent side of every two fixed blocks 16. The bottom end of the push plate 18 is in contact with the top of the working box 1 and the top end of the mold 12. The outside of the two guide rods 17 are slidably connected to the inner walls of the front and rear sides of the push plate 18, respectively. Servo motor 19 is installed on the top right rear side of the working box 1. The drive end of servo motor 19 is fixedly connected to rotating disk 20.

A push rod 23 is rotatably connected to the end of the second connecting rod 22 away from the first connecting rod 21. The end of the push rod 23 away from the second connecting rod 22 is fixedly connected to the right end of push plate 18.

[0021] The working principle of the injection molding product gate removal device provided by this utility model is as follows: First, in the preparation stage, the injection molded product to be processed is placed on the mold 12. The mold 12 is precisely installed on the inner wall of the top left side of the working box 1 via the assembly plate 13 and bolts 14, ensuring the stability of the mold 12 and providing reliable support for the subsequent gate removal operation. When the gate removal operation begins, the drive assembly starts first, and the drive motor 11 runs, driving the threaded rod 9 to rotate. Since the threaded rod 9 is externally threaded with a threaded block 10, and the threaded block 10 is slidably connected to the inside of the receiving support plate 5, the threaded block 10 will slide up and down along the inner wall of the receiving support plate 5 under the action of the rotation of the threaded rod 9. The front end of the threaded block 10 is fixedly connected to the sliding block 6, and the sliding block 6 is connected to the carrying plate 7. Therefore, the sliding of the threaded block 10 will drive the carrying plate 7 to move synchronously, so that the ultrasonic vibration block 8 installed on the inner wall of the carrying plate 7 is close to the injection molded product on the mold 12, allowing the vibration energy of the ultrasonic vibration block 8 to be released. The flow rate can be precisely transmitted to the gate connection point. Using the shearing force generated by high-frequency vibration, the gate waste is separated from the product. The gate waste remains on the mold 12. At this time, the servo motor 19 on the right rear side of the top of the working box 1 starts to work. Its drive end drives the rotating disk 20 to rotate. The first connecting rod 21 fixed outside the rotating disk 20 rotates accordingly. The end of the first connecting rod 21 away from the rotating disk 20 is rotatably connected to the second connecting rod 22. When the first connecting rod 21 rotates, it will drive the second connecting rod 22 to move. The end of the second connecting rod 22 away from the first connecting rod 21 is rotatably connected to the push rod 23. Then the push rod 23 will drive the push plate 18 fixedly connected to it to move. The bottom end of the push plate 18 contacts the top of the mold 12, and its front and rear inner walls are slidably connected to the guide rod 17. Under the action of the push rod 23, the push plate 18 slides along the guide rod 17, which can push the gate waste on the mold 12. After the gate waste separates from the product, the separated product falls from the position of mold 12 into the through hole 2 opened inside the left side of the working box 1 due to its own gravity. The inclined plate 3 fixed on the inner wall of the through hole 2 will guide the product to move towards the discharge hole 4 opened at the front left end of the working box 1. Finally, the product is discharged from the discharge hole 4, completing the automatic unloading of the product. The gate waste that is shaken off is partially left on the top of mold 12 or working box 1. Subsequently, the waste can be pushed and cleaned by the movement of push plate 18 in conjunction with the unloading plate 15, reducing the amount of manual cleaning.

[0022] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
