Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection molding technology, specifically to an injection molding machine with an automatic feeding structure. Background Technology
[0002] Injection molding machines, also known as injection molding machines or simply injection machines, are key plastic processing equipment widely used to manufacture thermoplastic or thermosetting plastic products of various shapes. Based on their structural design, injection molding machines are mainly divided into three types: vertical, horizontal, and all-electric. This equipment heats plastic material to a molten state and injects it into the mold cavity under high pressure, thereby accurately replicating the shape of the mold.
[0003] However, current injection molding machines on the market have some shortcomings in material handling. Specifically, traditional feeding methods rely on simple feeding troughs, which are not flexible enough when conveying materials to external equipment, posing challenges to smooth operation for users. Furthermore, when the feed rate is too high, blockages can easily occur inside the hopper, affecting not only the continuity of feeding but also increasing the difficulty of unblocking, thereby reducing production efficiency. Therefore, it is necessary to optimize the material handling system of injection molding machines to improve their overall performance and user-friendliness. In light of this, this project was developed through in-depth research into the aforementioned issues. Utility Model Content

The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.
[0022] Example
[0023] like Figure 1-4 As shown, the processing bracket 2 is mounted on the injection molding machine 1, the raw material box 3 is mounted on the processing bracket 2, and the flow guiding structure is connected to the raw material box 3 of the injection molding machine 1.
[0024] Specifically, the drainage structure includes: a stretching drive 4, a stretching threaded shaft 5, a trumpet-shaped gathering block 6, a pair of insert inner tubes 7, a Z-shaped feeding tube 8, several horizontal telescopic convex shafts 9, several horizontal telescopic concave shaft tubes 10, several horizontal telescopic spring columns 11, several lifting bearing blocks 12, several lifting limit shafts 13, several lifting sleeve springs 14, lifting extrusion shaft 15, lifting extrusion drive 16, an eccentric wheel 17, several horizontal telescopic magnets 18, a pair of toothed telescopic metal blocks 19, a pair of magnetic adsorption electromagnets 20, and a drainage assembly;
[0025] Specifically, the threaded shaft 5 is inserted into the top of the raw material box 3 via bearings; the drive end of the threaded shaft 5 is connected to the threaded shaft 5; the horn-shaped aggregating block 6 is installed on the inner bottom of the raw material box 3; a pair of insertable inner tubes 7 are inserted into the horn-shaped aggregating block 6 and the injection molding machine 1; the Z-shaped feeding pipe 8 is movably installed on the pair of insertable inner tubes 7; several horizontal telescopic convex shafts 9 are movably inserted into the inner sides of several horizontal telescopic concave shaft tubes 10, and the several horizontal telescopic convex shafts 9 are connected to both sides of the injection molding machine 1; several horizontal telescopic spring pillars 11 are installed into the inner sides of several horizontal telescopic concave shaft tubes 10, and the several horizontal telescopic spring pillars 11 are connected to several horizontal telescopic convex shafts 9; several lifting slots are provided on the processing bracket 2; several lifting bearing blocks 12 are movably inserted into several lifting slots. Inside the groove, several lifting limit shafts 13 are movably inserted into the inside of several lifting grooves, and several lifting shafts are movably inserted into several lifting bearing blocks 12. Several horizontal telescopic concave shaft tubes 10 are movably inserted into the inside of several lifting bearing blocks 12. Several lifting sleeve springs 14 are respectively sleeved on several lifting limit shafts 13. The lifting extrusion shaft 15 is inserted into the processing bracket 2. The driving end of the lifting extrusion drive 16 is connected to the lifting extrusion shaft 15. The eccentric wheel 17 is installed on the lifting extrusion shaft 15. Several horizontal telescopic magnets 18 are evenly installed on both sides of the Z-shaped feeding tube 8. A pair of toothed telescopic metal blocks 19 are respectively inserted into the processing bracket 2 in parallel. A pair of magnetic adsorption electromagnets 20 are respectively installed on a pair of toothed telescopic metal blocks 19. The diversion assembly is installed inside the Z-shaped feeding tube 8.
[0026] It should be noted that, in the above process, the stretching drive 4 drives the stretching threaded shaft 5 on the drive end, thereby stretching the material inside the raw material box 3, avoiding the phenomenon of molding blockage. At the same time, the raw material is guided into the inner tube 7 by the trumpet-shaped aggregating block 6, and then guided into the inner side of the Z-shaped feeding tube 8 by the inner tube 7. The material is pushed by the guiding component on the Z-shaped feeding tube 8. The lifting extrusion drive 16 drives the lifting extrusion shaft 15 on the drive end of the lifting extrusion drive 16. The lifting extrusion shaft 15 drives the eccentric wheel 17 on it. The rotation of the eccentric wheel 17 drives the Z-shaped feeding tube 8 on it, so that the Z-shaped feeding tube 8 drives several horizontal telescopic convex shafts 9 on it to move up and down stably. The horizontal telescopic convex shafts 9 drive the horizontal telescopic concave shaft tubes 10 on them to move up and down stably. At the same time, the horizontal telescopic concave shaft tubes 10 drive the lifting bearing block 12 on them, so that the lifting bearing block 12 moves up and down stably along the lifting limit shaft 13. The vertical compression is converted into elastic deformation of the lifting spring 14, causing the Z-shaped feeding tube 8 to vibrate vertically. Simultaneously, a pair of magnetic electromagnets 20 are energized one by one, energizing a pair of toothed telescopic metal blocks 19. These blocks magnetically repel several horizontal telescopic magnets 18, causing the Z-shaped feeding tube 8 to extend and retract horizontally. The Z-shaped feeding tube 8 then drives the horizontal telescopic convex shaft 9 to extend and retract horizontally, stabilizing its position within the horizontal telescopic concave shaft tube 10. The horizontal telescopic spring provides stable buffering for the convex shaft 9, converting horizontal kinetic energy into elastic deformation. This allows the Z-shaped feeding tube 8 to vertically lift and horizontally extend and retract, vibrating the raw material inside the Z-shaped feeding tube 8 in both vertical and horizontal directions to prevent blockage.
[0027] like Figure 1-4 As shown, the diversion assembly includes: a feeding drive 21, a feeding drive screw shaft 22, and diversion blades 23;
[0028] Specifically, the feeding drive screw shaft 22 is inserted into the Z-shaped feeding pipe 8, the driving end of the feeding drive machine 21 is connected to the feeding drive screw shaft 22, and the guide vane 23 is installed on the feeding drive screw shaft 22;
[0029] It should be noted that, as described above, the operation of the feeding drive machine 21 drives the feeding drive screw shaft 22 on the drive end of the feeding drive machine 21 to rotate, and the feeding drive screw shaft 22 drives the guide vane 23 on it to rotate, thereby feeding the raw material stably and horizontally along the Z-shaped feeding pipe 8.
[0030] As a preferred option, the processing support 2 is further provided with a magnetic percussion device.
[0031] As a preferred embodiment, the Z-shaped feeding tube 8 and the pair of insert inner tubes 7 are further provided with buffer rubber rings.
