Description

Technical Field

[0001] This utility model relates to the field of injection molding equipment technology, and in particular to a molten material filtering device. Background Technology

[0002] Injection molding machines are used to mold thermoplastic or thermosetting plastics into various shapes of plastic products using plastic molds. Injection molding machines heat plastic and apply high pressure to molten plastic, causing it to be injected and fill the mold cavity. Molten plastic is injected from the nozzle into the mold cavity, so the nozzle is an important component of the injection molding machine.

[0003] Nozzles are used when conveying molten material in injection molding machines. However, common injection molding machine nozzles for conveying molten material do not have a filtering function. As a result, impurities in the molten material may be present, causing blockage of the nozzle orifice. However, simply adding a filter may not provide good stability during use, reducing the practicality of the device. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a molten material filtration device that exhibits good filtration stability.

[0005] A molten material filtering device according to an embodiment of the present invention includes a nozzle, a conveying pipe, a filtering mechanism, and a positioning mechanism. The conveying pipe is connected to the top of the nozzle. The filtering mechanism is disposed on the outer wall of the conveying pipe, and a top plate is disposed inside the filtering mechanism. A connecting pipe is fixedly connected inside the top plate, and a connector is fixedly connected to the top of the connecting pipe. The positioning mechanism is disposed on the outer wall of the conveying pipe and includes a support arm. The support arm is fixedly connected to the outer wall of the conveying pipe. A support sleeve is fixedly connected to one side of the support arm. A cylinder is fixedly connected to the inner ring of the support sleeve.

[0006] It has at least the following beneficial effects: The positioning mechanism allows the external threaded tube to be unscrewed from the inner wall of the internal threaded tube, enabling disassembly of the conveying pipe. The filter bucket can then be pulled upwards for easy cleaning of impurities filtered by the filter, reducing the likelihood of molten material clogging the nozzle and facilitating injection molding. The filtering mechanism also allows the pull block to engage with the front of the positioning block, preventing the spring from pushing the retaining shaft and facilitating further disassembly and cleaning. The cooperation between the retaining shaft and the limiting block ensures the stability of the connection between the external and internal threaded tubes, providing excellent stability during use and enhancing the device's practicality.

[0020] Reference Figures 1 to 5 This utility model discloses a molten material filtering device, including a nozzle 100, a conveying pipe 700 fixedly connected to the top of the nozzle 100, a filtering mechanism 500 provided on the outer wall of the conveying pipe 700, a positioning mechanism 400 provided on the outer wall of the conveying pipe 700, a top plate 600 provided inside the filtering mechanism 500, a connecting pipe 300 fixedly connected inside the top plate 600, and a connector 200 fixedly connected to the top of the connecting pipe 300. The positioning mechanism 400 includes a support arm 410, which is fixedly connected to the outer wall of the conveying pipe 700. A support sleeve 411 is fixedly connected to one side of the support arm 410. A cylinder 420 is fixedly connected to the inner ring of the support sleeve 411. A spring 422 is fixedly connected to the inner wall of the cylinder 420. A round block 430 is fixedly connected to the end of the spring 422 away from the inner wall of the cylinder 420. A retaining shaft 433 is fixedly connected to the side of the round block 430 away from the spring 422. A pull shaft 440 is fixedly connected to the side of the round block 430 away from the retaining shaft 433. A pull block 444 is rotatably connected to the outer wall of the pull shaft 440. A positioning block 455 is fixedly connected to the front of the cylinder 420. A limit block 450 is provided at the bottom of the filtering mechanism 500.

[0021] In some embodiments, the spring 422 is sleeved on the outer wall of the pull shaft 440, and the circular block 430 is slidably connected to the inner wall of the cylinder 420, so that the circular block 430 can move stably to compress the spring 422.

[0022] In some embodiments, a first hole is provided on the back of the cylinder 420, and the retaining shaft 433 passes through the first hole, so that the retaining shaft 433 can move through the first hole.

[0023] In some embodiments, a second hole is provided on the front side of the cylinder 420, and the pull shaft 440 passes through the second hole, so that the pull shaft 440 can move through the second hole.

[0024] In some embodiments, the limiting block 450 has a locking hole inside, and the locking shaft 433 is inserted into the inner wall of the locking hole, so that the locking shaft 433 can limit the limiting block 450 through the locking hole.

[0025] Reference Figures 1 to 5 The filter mechanism 500 includes an internally threaded tube 510, which is fixedly connected to the outer wall of the top plate 600. A rotating sleeve 522 is fixedly connected to the outer wall of the internally threaded tube 510. A positioning ring 511 is fixedly connected to the bottom of the top plate 600. A positioning frame 533 is provided on the inner wall of the conveying pipe 700. A filter bucket 520 is fixedly connected to the inner ring of the positioning frame 533. An externally threaded tube 530 is fixedly connected to the outer wall of the conveying pipe 700 to facilitate the connection and installation of the external filter bucket 520.

[0026] In some embodiments, the internally threaded tube 510 is fixedly connected to the top of the limiting block 450, and the internally threaded tube 510 is threadedly connected to the outer wall of the externally threaded tube 530, so that the conveying tube 700 and the top plate 600 can be better connected.

[0027] In some embodiments, the filter bucket 520 has filter holes on its outer wall and bottom, the conveying pipe 700 has slots on its inner wall, and the positioning frame 533 is movably connected to the inner wall of the slot to provide stable support for the filter bucket 520.

[0028] In actual operation, when this device is used, it can first be installed on the injection molding machine through the connector 200. Then, the molten material can be conveyed to the inside of the nozzle 100 through the connector 200. At the same time, during the conveying of the molten material, the filter bucket 520 can filter the impurities contained in the molten material, so that the impurities can be filtered into the inside of the filter bucket 520. After the injection molding work is completed, the pull block 444 can be pulled to move, so that the retaining shaft 433 can be pulled out from the inside of the limiting block 450, thus removing the limitation on the limiting block 450. Then, one hand can hold the rotating sleeve 522, and the other hand can rotate the conveying pipe 700, so that the external threaded pipe 530 can be unscrewed from the inner wall of the internal threaded pipe 510. Then, the conveying pipe 700 can be disassembled, and the filter bucket 520 can be pulled out upwards to facilitate the cleaning of the impurities filtered by the filter bucket 520. At the same time, it can reduce the blockage of the nozzle by impurities generated by the molten material, and facilitate the injection molding work.

[0029] Understandably, when the pull block 444 is pulled, it can drive the pull shaft 440 to move, which in turn drives the round block 430 to move. The round block 430 can compress the spring 422. When the retaining shaft 433 is completely removed from the inside of the limiting block 450, the pull block 444 is then positioned on the front of the positioning block 455. The pull block 444 can then be rotated to make a circular motion along the axis of the pull shaft 440, allowing it to engage with the front of the positioning block 455. This prevents the spring 422 from pushing the retaining shaft 433, facilitating further disassembly and cleaning. Simultaneously, the cooperation between the retaining shaft 433 and the limiting block 450 ensures the stability of the connection between the external threaded pipe 530 and the internal threaded pipe 510, providing good stability during use and enhancing the practicality of the device.

[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
