Detailed Implementation

[0024] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0025] like Figure 1 , 2 As shown in Figure 4, a preferred embodiment of the injection molding machine feeding mechanism of this utility model includes a base plate 1 and a feeding hopper 2. The base plate 1 is fixedly connected to the injection molding machine body. Specifically, one end of the base plate 1 is provided with a feeding port 11 for communicating with the injection molding machine body. The periphery of the feeding port 11 is provided with a connecting hole, and the connecting hole is connected to the injection molding machine body by bolts. The upper end of the feeding hopper 2 is provided with a feeding port, which can be connected to a raw material hopper for feeding. Specifically, a feeding plate can be provided on the feeding port, and a feeding pipe is provided on the feeding plate. The feeding pipe is connected to the raw material hopper. The lower end of the feeding hopper 2 is provided with a discharge port communicating with the feeding port. The discharge port is connected to the feeding port. A magnetic separator assembly 3 is detachably provided inside the feeding hopper.

[0026] Based on the above-mentioned technical features, the injection molding machine feeding mechanism has a removable iron remover assembly 3 installed inside the feeding hopper 2. When the raw material is fed into the injection molding machine, it enters the feeding hopper 2 through the feeding port. Under the action of the iron remover assembly 3, the raw material is de-ironed. After iron removal, the raw material enters the feeding port 11 through the discharge port and finally enters the main body of the injection molding machine. This avoids iron filings from entering the main body of the injection molding machine, which could damage the screw of the conveying mechanism and block the hot runner, thus ensuring the normal operation of production.

[0027] In this embodiment, during normal iron removal, the iron separator assembly 3 is fixed. When there is a large amount of iron filings on the iron separator assembly 3 that needs to be removed, the iron separator assembly 3 is disassembled. After the iron filings are removed, the iron separator assembly 3 is reinstalled. Specifically, a mounting hole is provided on one side of the feed hopper 2. The iron separator assembly 3 is inserted into the inside of the feed hopper 2 through the mounting hole and locked by the locking assembly 4. To disassemble, simply loosen the locking assembly 4 first, and then remove the iron separator assembly 3 from the mounting hole.

[0028] Please see the appendix Figure 5 The magnetic separator assembly 3 includes a connecting plate 31, which has an inner surface and an outer surface arranged opposite to each other. Multiple magnetic rods 32 are provided on the inner surface. To ensure the stability of the multiple magnetic rods 32, an integrated plate 33 can also be provided. The integrated plate is arranged opposite to the connecting plate 31, and the other end of each magnetic rod 32 is connected to the integrated plate 33, thereby integrating the multiple magnetic rods 32 into a whole and ensuring the overall stability of the magnetic separator assembly 3. The magnetic rods 32 need to withstand a high temperature of 180 degrees Celsius to avoid demagnetization due to high temperature. Their strength can be around 1000GS, preferably made of ferritic material. When the magnetic rods 32 are inserted into the inside of the feed hopper 2 through the mounting holes, and the inner surface is in contact with the outer wall of the feed hopper 2, the locking assembly 4 locks the connecting plate 31. A handle can be provided on the outer surface of the connecting plate 31 for convenient installation and disassembly of the magnetic separator assembly 3.

[0029] Please see the appendix Figures 1-3 The mounting hole is provided on the first side wall of the feed hopper 2, and the two sides of the first side wall are respectively provided with hinge seats 21; there are two locking components 4, which correspond one-to-one with the two hinge seats 21. The locking component 4 includes a connecting shaft 41 provided on the hinge seat 21 and a sleeve 42 sleeved on the connecting shaft 41. The side wall of the sleeve 42 is provided with a screw 43, and the screw 43 is provided with a nut 44. The connecting plate 31 is provided with a locking groove 34. When the screw 43 is located in the locking groove 34 and the nut is rotated 44 to abut against the outer wall of the connecting plate 31, the connecting plate 31 is locked.

[0030] As described above, when there are many iron filings on the magnetic rod 32, the iron remover assembly 3 needs to be disassembled for cleaning. At this time, the feed hopper 2 may still be connected to the raw material silo. Therefore, it is necessary to disconnect the connection between the raw material silo and the feed hopper 2 to prevent raw materials from entering the feed hopper 2 from the raw material silo. Therefore, a control plate 22 can be laterally movable inside the feed hopper 2. The control plate 22 is used to control the opening and closing of the feed inlet. The control plate 22 can be connected to a pull rod. When the control plate 22 needs to be moved, force can be applied to the pull rod, making the operation simple and convenient.

[0031] In some embodiments, different raw materials need to be changed, requiring the feed hopper 2 to be connected to different raw material bins. In this case, besides disconnecting from the raw material bins, raw materials may remain inside the feed hopper 2, requiring discharge. Therefore, a discharge port 12 can be provided at the other end of the base plate 1, with a discharge pipe 40 connected to it. A slide block 5 is slidably provided on the base plate 1, and the feed hopper 2 is located at the upper end of the slide block 5, enabling communication with either the discharge port 12 or the feeding port 11. That is, during normal feeding, the slide block 5 is connected to the feeding port 11; when material needs to be changed and the raw materials inside the feeding mechanism need to be discharged, the slide block 5 is connected to the discharge port 12. To facilitate the movement of the slide block 5 and ensure its movement accuracy, guide strips 13 extending along its length are provided on both sides of the base plate 1, and guide blocks 6 are provided on both sides of the slide block 5, with guide grooves 61 that cooperate with the guide strips 13. That is, when the slide block moves, it achieves sliding guidance through the cooperation of the guide groove 61 and the guide bar 13, so as to ensure the movement accuracy.

[0032] Meanwhile, to facilitate the movement of the slide block 5, four rollers 7 are provided at the bottom of the slide block 5, with two rollers on each side of the slide block 5. However, while the rollers 7 facilitate the movement of the slide block 5, there is also a risk that the slide block 5 may move automatically during operation, thus affecting the feeding. To avoid this situation, a slot 14 is provided on the base plate 1 corresponding to the feeding port 11; a stop strip 8 is also provided on the slide block 5. Specifically, one end of the stop strip 8 is hinged to the slide block 5, and the other end of the stop strip 8 is provided with a brake block 9 that cooperates with the slot 14. When the slide block 5 moves to communicate with the feeding port 11, the stop strip 8 is rotated to make the brake block 9 engage with the slot 14, thus ensuring that the slide block 5 and the base plate 1 are relatively fixed, thereby ensuring normal feeding.

[0033] The discharge port 12 may or may not have the slot 14. Since the discharge process is short and there is no vibration during the discharge process, the slide 5 will not move. Even if it does slide, it can be manually controlled to ensure the stability of the slide 5.

[0034] Please also refer to the appendix. Figure 4Additionally, it should be noted that during the movement of the slide block 5, to prevent raw materials inside the feed hopper 2 from falling between the slide block 5 and the seat plate 1 and affecting the movement, the upper end of the slide block 5 is provided with an opening and closing plate 10. The opening and closing plate 10 is driven to slide by a driving mechanism to realize the connection or disconnection between the feed hopper 2 and the slide block 5. That is, when unloading is required, the opening and closing plate 10 is first driven by the driving mechanism to disconnect the connection between the feed hopper 2 and the slide block 5, and then the slide block 5 is moved. When the slide block 5 moves to the discharge port 12, the driving mechanism drives the opening and closing plate 10 to connect the feed hopper 2 and the slide block 5, and the raw materials inside the feed hopper 2 are discharged and collected through the discharge port 12.

[0035] In this embodiment, the driving mechanism includes a frame 20 disposed on the outer wall of the slide block, and a cylinder 30 is provided on the frame 20. The telescopic rod of the cylinder 30 is connected to the opening and closing plate 10, thereby realizing the movement of the opening and closing plate 10 driven by the cylinder 30. The cylinder 30 can also be a hydraulic cylinder, an electric cylinder, etc.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
