Description

Technical Field

[0001] This utility model belongs to the field of injection molding machine feeding technology, specifically a feeding mechanism for an injection molding machine. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment used to make various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They are divided into vertical, horizontal, and all-electric types. Injection molding machines heat the plastic and apply high pressure to the molten plastic, causing it to be injected and fill the mold cavity to obtain the finished product. Currently, when heating and melting the raw material, the heating is usually carried out from the inner wall of the heating device, and the raw material melts gradually from the outside to the inside. The heating efficiency is low and not uniform enough, which affects the melting efficiency. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a feeding mechanism for an injection molding machine, which solves the problem that the heating efficiency is low and not uniform as the raw materials in the pile gradually melt from the outside to the inside, thus affecting the melting efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism for an injection molding machine, comprising a molten feed chamber, a feed inlet connected to the molten feed chamber, a first motor installed on one side of the molten feed chamber, a feeding auger connected to the output shaft of the first motor, a storage tank installed above the molten feed chamber, a heating plate installed between the inner and outer walls of the storage tank, a filling port connected to one side above the storage tank, and a discharge port connected to the bottom of the storage tank;

[0005] A heating rod is installed inside the storage tank. A toothed ring is rotatably connected to the inner wall of the storage tank. A second motor is installed above the storage tank. A drive wheel is installed on the output shaft of the second motor. A synchronous belt is installed on the drive wheel. A driven wheel is connected to the synchronous belt. A connecting rod is connected below the driven wheel. A gear is connected to one end of the connecting rod.

[0006] As a further embodiment of this utility model: the drive wheel and the connecting rod are both rotatably connected above the storage tank, and the gear is meshed with the toothed ring.

[0007] As a further embodiment of this utility model: a plurality of heating support rods are installed on the heating rod, and the eight heating support rods are evenly arranged in a centrally symmetrical manner.

[0008] As a further embodiment of this utility model: multiple scrapers are connected below the toothed ring, and multiple stirring plates are connected to the scrapers, with the scrapers in contact with the inner wall of the storage tank.

[0009] As a further embodiment of this utility model: an insulation layer is provided on the inner wall of the molten propulsion chamber, and the inlet and outlet are connected.

[0010] As a further embodiment of this utility model: one end of the feeding auger is connected to a thin rod, and a tapered plate is connected to the thin rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. The feeding mechanism of this injection molding machine is equipped with a drive wheel, a synchronous belt, a driven wheel, gears, a toothed ring, a stirring plate, a heating plate, a heating rod, and a heating support rod. During operation, the heating plate heats up, heating the inner wall and outer side of the storage tank material. At the same time, the heating rod and heating support rod heat up, heating the inner side material, thereby increasing the heating and melting area and improving melting efficiency. The operator starts the second motor to rotate the drive wheel. The cooperation of the drive wheel, synchronous belt, and driven wheel drives the gear to rotate, which in turn drives the toothed ring to rotate, causing the scraper and stirring plate to stir the material, so that the material is heated evenly and the mixing and heating efficiency is improved.

[0013] 2. The feeding mechanism of this injection molding machine, through the setting of a first motor, a feeding auger, an insulation layer, a thin rod, and a conical plate, allows the raw material in the storage tank to enter the molten feed chamber through the discharge port. At this time, the first motor will rotate the feeding auger, enabling it to push the molten raw material to move, thereby completing the feeding work. Meanwhile, the insulation layer will keep the internal temperature warm to prevent the raw material from condensing due to excessively low temperature. The thin rod will rotate together with the feeding auger, thereby driving the conical plate to rotate, causing the conical plate to stir the raw material at the outlet of the molten feed chamber, preventing the raw material from clogging the outlet.

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-5 As shown, this utility model provides a technical solution: a feeding mechanism for an injection molding machine, including a molten feed chamber 1, a feed inlet 2 connected to the molten feed chamber 1, a first motor 3 installed on one side of the molten feed chamber 1, and a heat insulation layer 20 provided on the inner wall of the molten feed chamber 1. The feed inlet 2 is connected to the discharge outlet 8. When the raw material enters the molten feed chamber 1 through the feed inlet 2, the heat insulation layer 20 will keep the raw material warm, thereby preventing the heat from decreasing and avoiding the raw material from condensing in the molten feed chamber 1.

[0022] The output shaft of the first motor 3 is connected to a feeding auger 4. One end of the feeding auger 4 is connected to a thin rod 21, and a conical plate 22 is connected to the thin rod 21. When the first motor 3 rotates the feeding auger 4 to convey raw materials, the feeding auger 4 will drive the thin rod 21 to rotate together, thereby causing the conical plate 22 to stir the raw materials at the outlet of the molten feed chamber 1, so as to avoid the raw materials from blocking and causing blockage.

[0023] A storage tank 5 is installed above the melting propulsion chamber 1. A heating plate 6 is installed between the inner and outer walls of the storage tank 5. A filling port 7 is connected to one side of the upper part of the storage tank 5, and a discharge port 8 is connected to the lower part of the storage tank 5. A heating rod 9 is installed inside the storage tank 5. Multiple heating support rods 19 are installed on the heating rod 9. There are eight heating support rods 19 in total, which are evenly arranged in a centrally symmetrical manner. The heating rod 9 and the heating support rods 19 heat the inner side of the pile of raw materials, thereby cooperating with the heating plate 6 to simultaneously heat multiple parts of the raw materials, improving heating efficiency and heating uniformity, and avoiding uneven melting and mixing of raw materials due to uneven heating.

[0024] A toothed ring 10 is rotatably connected to the inner wall of the storage tank 5. Multiple scrapers 17 are connected below the toothed ring 10, and multiple stirring plates 18 are connected to the scrapers 17. The scrapers 17 are in contact with the inner wall of the storage tank 5. When the toothed ring 10 drives the scrapers 17 to rotate, the scrapers 17 can scrape off the raw materials adhering to the inner wall of the storage tank 5, avoiding the raw materials remaining on the inner wall of the storage tank 5 and causing pollution and waste. The multiple stirring plates 18 on the scrapers 17 can stir the raw materials when the toothed ring 10 rotates, preventing the raw materials from piling up and promoting the uniform heating of the raw materials.

[0025] A second motor 11 is installed above the storage tank 5. A drive wheel 12 is installed on the output shaft of the second motor 11. A timing belt 13 is installed on the drive wheel 12. A driven wheel 14 is connected to the timing belt 13. A connecting rod 15 is connected below the driven wheel 14. A gear 16 is connected to one end of the connecting rod 15. The drive wheel 12 and the connecting rod 15 are rotatably connected above the storage tank 5. The gear 16 meshes with the toothed ring 10. The second motor 11 can drive the drive wheel 12 to rotate, and the drive wheel 12 can drive the driven wheel 14 through the timing belt 13, causing the gear 16 to rotate. Thus, the meshing of the gear 16 with the toothed ring 10 drives the scraper 17 and the stirring plate 18 to rotate to complete the stirring of the raw materials.

[0026] The working principle of this utility model is as follows:

[0027] The operator starts the first motor 3 and the second motor 11, filling the raw material into the storage tank 5 through the filling port 7. During operation, the heating plate 6 heats the inner wall of the storage tank 5, causing the raw material on the outside to melt. At the same time, the heating rod 9 and the heating support rod 19 heat the raw material on the inside, thereby increasing the melting area and improving the melting efficiency. Meanwhile, the second motor 11 rotates the drive wheel 12, which drives the driven wheel 14 through the synchronous belt 13, causing the gear 16 to rotate. The meshing of the gear 16 with the toothed ring 10 drives the toothed ring 10 to rotate, causing the scraper 1... 7. The raw materials are stirred by the stirring plate 18 to ensure uniform heating and improve mixing and heating efficiency. Then, the raw materials in the storage tank 5 will enter the melting propulsion chamber 1 through the discharge port 8. The first motor 3 will rotate the feeding auger 4, which will push the molten raw materials to move, thereby completing the feeding work. At the same time, the insulation layer 20 will keep the internal temperature warm to prevent the raw materials from condensing due to low temperature. The thin rod 21 will rotate with the feeding auger 4, thereby driving the conical plate 22 to rotate, so that the conical plate 22 stirs the raw materials at the outlet of the melting propulsion chamber 1 to prevent the raw materials from blocking the outlet.
