[0024] like Figures 1 to 6 As shown, an embodiment of the present invention provides an injection molding device for plastic processing, including a leg 1, four legs 1 are provided, the tops of the four legs 1 are fixedly connected to a support frame 2, a support plate 3 is fixedly connected between the four legs 1, an energy transmission component is provided on the outside of the support frame 2, the energy transmission component includes a water storage tank 4 fixedly connected to the inside of the support frame 2, a circulation pump 5 is fixedly connected to the bottom of the water storage tank 4, a first connecting pipe 6 is fixedly connected to the output end of the circulation pump 5, a second connecting pipe 7 is fixedly connected to the input end of the circulation pump 5, and the second connecting pipe 7 runs through the water storage tank 4 and is fixedly connected to the water tank 4, the end of the second connecting pipe 7 is fixedly connected to the first conversion pipe 8, the end of the first conversion pipe 8 is fixedly connected to the third connecting pipe 9, the third connecting pipe 9 penetrates the water tank 4 and is fixedly connected to the water tank 4, the end of the third connecting pipe 9 is fixedly connected to the second conversion pipe 10, the end of the second conversion pipe 10 is fixedly connected to the end of the first connecting pipe 6, the top of the water tank 4 is connected to the water inlet pipe 11, the inside of the water tank 4 is fixedly connected to a water pump, the output end of the water pump is fixedly connected to a water outlet pipe, the water outlet pipe penetrates the water tank 4 and is fixedly connected to the water tank 4.

[0025] Among them, the heat overflowing from the working tank 13 is absorbed by the water inside the first conversion tube 8, and then the heated water is transmitted to the inside of the third connecting tube 9 through the circulation pump 5, so that the hot water is transmitted to the inside of the second conversion tube 10, and then the hot water is transmitted to the inside of the first connecting tube 6, and then the water is transmitted to the inside of the second connecting tube 7 through the circulation pump 5, and then the water is transmitted to the inside of the first conversion tube 8, so as to complete the water circulation and transfer the water temperature, so as to improve the energy utilization rate, thereby reducing the energy waste, and the excess heat is secondary absorbed by the water in the water storage tank 4, so as to further improve the heat utilization rate.

[0026] like Figure 2 As shown, a working assembly is arranged inside the first conversion tube 8, and the working assembly includes a working tank 13 fixedly connected to the inside of the first conversion tube 8, a heating block 14 is fixedly connected to the inside of the working tank 13, a cover 12 is fixedly connected to the top of the inner cavity of the water tank 4, a feed pipe 15 is connected to the inside of the cover 12, and the feed pipe 15 passes through the water tank 4 and is fixedly connected to the water tank 4.

[0027] The plastic is transferred to the working tank 13 through the feed pipe 15, and then melted by the heating block 14. The excess heat can be transferred to the water in the water tank 4 to heat the water, and the water in the first conversion tube 8 is also heated at the same time.

[0031] Among them, the outflow of the melted plastic is controlled by the valve 21. When the melted plastic starts to flow, the melted plastic will enter the discharge pipe 19. At this time, the melted plastic will pass through the sieve hole 20, and will come into contact with the bubbles inside the melted plastic through the sieve hole 20, thereby breaking up the bubbles, so that the internal gas can overflow to the outside through the feed pipe 15.

[0032] like Figure 5 As shown, a transmission component is arranged on the outside of the feeding tube 19, and the transmission component includes a material output tube 22 which is connected to the inside of the feeding tube 19, and a bearing 24 is rotatably connected to the end of the material output tube 22. Two bearings 24 are arranged, and a pushing cylinder 25 is rotatably connected between the two bearings 24. An injection nozzle 26 is rotatably connected to the end of the second bearing 24.

[0033] The melted plastic is transferred to the inside of the push cylinder 25 through the material output pipe 22, so that the melted material is transferred to the inside of the injection nozzle 26, so that the melted plastic is squeezed out, so as to complete the injection molding.

[0034] like Figure 6 As shown, a transmission assembly is provided on the top of the support plate 3, and the transmission assembly includes a second motor 28 fixedly connected to the outer side of the positioning plate 23, a second transmission rod 29 is fixedly connected to the transmission end of the second motor 28, and the end of the second transmission rod 29 is rotatably connected to another positioning plate 23, and two driving gears 30 are fixedly connected to the outer side of the second transmission rod 29, and a driven gear 31 is meshed with the outer side of the driving gear 30, and the driven gear 31 is fixedly connected to the outer side of the pushing cylinder 25.

[0037] The second conversion tube 10 transfers heat to the inside of the push tube 25, thereby reducing the solidification of the melted plastic, thereby keeping the melted plastic in a good state before injection molding, thereby ensuring the quality of injection molding.

[0038] Working principle and use process: After the plastic enters the working tank 13 through the feed pipe 15, the plastic is then heated by the heating block 14, and the first transmission rod 17 is driven to rotate by the first motor 16, thereby driving the first spiral feeding piece 18 to rotate, so as to stir the plastic, thereby accelerating the melting process of the plastic and reducing the retention of air in the plastic. During the heating process of the plastic, the heat overflowing from the working tank 13 is absorbed by the water inside the first conversion tube 8, and then the heated water is transmitted to the inside of the third connecting tube 9 through the circulation pump 5, thereby transmitting the hot water to the inside of the second conversion tube 10, and then transmitting the hot water to the inside of the first connecting tube 6, and then transmitting the water to the inside of the second connecting tube 7 through the circulation pump 5, and then transmitting the water to the inside of the first conversion tube 8, thereby completing the water circulation and transmitting the water temperature, thereby improving the utilization rate of energy, thereby reducing the waste of energy, and the excess heat is secondary absorbed by the water inside the water storage tank 4, thereby further improving the utilization rate of heat.
