[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] The present invention provides an efficient feeding device for an injection molding device, as Figures 1 - 3 shown, which includes a base 2. A support platform 3 is installed on the top of one end of the base 2. One side of the support platform 3 is connected with a feeding assembly 4. One end of the feeding assembly 4 is connected with a deflector 5. One side of the deflector 5 is connected with the injection port of the mold 1. A cleaning liquid storage cavity is arranged inside the support platform 3 and below the feeding assembly 4. A baffle 34 is arranged on the top of the cleaning liquid storage cavity. The baffle 34 is driven by a driving cylinder 32 to move horizontally. The driving cylinder 32 is fixed on the bottom side of the feeding cylinder 41. One side of the baffle 34 slides through the side wall of the cleaning liquid storage cavity and extends to the outside and is fixedly connected with the extending rod of the driving cylinder 32. This device uses the base 2 to support the entire structure to ensure the stability of the device. The feeding assembly 4 installed on the support platform 3 is responsible for stably and continuously feeding the material into the deflector 5, and then evenly distributing it to the injection port of the mold 1, effectively improving the molding quality and production efficiency of the injection molded product.

[0022] At the same time, the device also considers the convenience of cleaning and maintenance. The cleaning liquid storage cavity arranged inside the support platform 3 can store the cleaning liquid generated after cleaning, and the baffle 34 on the top can move horizontally under the drive of the driving cylinder 32, so as to conveniently control the discharge of the cleaning liquid and effectively clean key components such as the feeding assembly 4. This design not only simplifies the cleaning process, but also reduces the maintenance cost, further improving the overall practicality and production efficiency of the device.

[0023] In this embodiment, a feeding port 51 is arranged in the middle of the deflector 5. A plurality of shunt channels 52 are connected in the circumferential direction of the inner wall of the feeding port 51. The outer ends of the plurality of shunt channels 52 away from the feeding port 51 are provided with flow inlets 521. The flow inlets 521 are docked with different injection ports on the mold 1 to ensure that the injection liquid flows into different positions of the mold 1.

[0024] Specifically, a plurality of sub-runners 52 are arranged in a circular and equally spaced manner to ensure that the injection liquid flows into the mold 1 evenly.

[0025] Furthermore, the feeding assembly 4 includes a feeding cylinder 41. One end of the feeding cylinder 41 penetrates and extends into the support platform 3 and is fixedly connected to the inner wall of the support platform 3, and the other end is connected to the feeding port 51 of the diversion plate 5. A rotating shaft 42 is rotatably installed inside the feeding cylinder 41, and a spiral feeding blade 43 is installed outside the rotating shaft 42. One end of the rotating shaft 42 is driven to rotate by a driving motor 44. The driving motor 44 is fixed on the outer wall of the support platform 3, and the output shaft of the driving motor 44 rotates through the side wall of the support platform 3 and extends into its interior and is fixedly connected to one end of the rotating shaft 42. By driving the spiral feeding blade 43 to move through the driving motor 44, the spiral feeding blade 43 pushes the material to move in the feeding cylinder 41 towards the feeding port 51, thereby performing a uniform feeding operation.

[0026] Furthermore, a drain port 45 is provided at the bottom of the feeding cylinder 41 and near the cleaning liquid storage cavity. A baffle 34 is slidably fitted on the outer wall of the bottom side of the feeding cylinder 41 to block the drain port 45. By driving the cylinder 32 to drive the baffle 34 to move away from the drain port 45, the waste after cleaning inside the feeding cylinder 41 is discharged from the drain port 45 and flows into the cleaning liquid storage cavity, preventing the waste liquid from flowing into the mold 1.

[0027] Furthermore, a through cleaning port 33 is provided on one side outer wall of the support platform 3, which facilitates the cleaning and recycling of the waste residue; a sealing cover plate is installed outside the cleaning port 33 to ensure the sealing of the cleaning port 33 usually; a liquid extraction pipe is installed on the sealing cover plate to facilitate the extraction and recovery of the waste liquid inside the support platform 3.

[0028] Furthermore, a feeding pipe 31 is provided at the top of the support platform 3. The bottom of the feeding pipe 31 penetrates through the top of the feeding pipe 31 and is connected to the top side of the feeding cylinder 41, so that the bottom of the feeding pipe 31 is communicated with the inside of the feeding cylinder 41; a cleaning pump 311 is installed on one side of the top of the feeding pipe 31. The output end of the cleaning pump 311 is communicated with the inside of the feeding pipe 31, and the input end of the cleaning pump 311 is connected with a cleaning liquid connection pipe 312. Through the cleaning liquid connection pipe 312, it is convenient to introduce cleaning liquid into the feeding pipe 31, and then to flush the inside of the feeding cylinder 41. By driving the driving motor 44 to drive forward and reverse movements, the cleaning action is realized, and the cleaning liquid is discharged from the drain port 45 through the reverse rotation of the driving motor 44.

[0029] When the high-efficiency feeding device of the injection molding equipment of the present utility model is in use, first, the material required for injection molding is added into the feeding cylinder 41 through the feeding pipe 31. Subsequently, the driving motor 44 is started to drive the rotating shaft 42 and the spiral feeding blade 43 outside it to rotate, so as to stably and continuously feed the material into the diversion plate 5.

[0030] On the deflector 5, the material enters through the feed port 51 in the middle and evenly flows into the mold 1 along a number of annular and equally spaced shunt channels 52. The outer ends of the shunt channels 52 are provided with inlets 521, and these inlets 521 are docked with different injection ports on the mold 1 to ensure that the material can flow into each position of the mold 1 evenly and quickly, effectively improving the molding quality of the injection-molded product.

[0031] When cleaning is required, the cleaning pump 311 is started, sucks in the cleaning liquid through the cleaning liquid connection pipe 312, and conveys it into the feeding pipe 31. The cleaning liquid then enters the feeding cylinder 41 to wash the inside of the feeding cylinder 41. Driven by the forward and reverse rotation of the driving motor 44, the cleaning liquid can fully clean the inside of the feeding cylinder 41 and the spiral feeding blade 43. At this time, the inlets 521 and the different injection ports on the mold 1 are in a closed state to prevent the cleaning liquid from flowing into the mold 1. Then the driving cylinder 32 drives the baffle 34 to move horizontally, opens the drain port 45, so that the waste liquid can be discharged smoothly. The waste liquid after cleaning is discharged through the drain port 45 at the bottom of the feeding cylinder 41 and falls into the cleaning liquid storage cavity inside the support table 3. At the same time, the sealing cover plate outside the cleaning port 33 ensures the usual sealing performance, and the liquid suction pipe installed on the sealing cover plate facilitates sucking dry the waste liquid in the support table 3 for recycling, and the waste residue can be cleaned and recycled through the cleaning port 33 on one side of the support table 3.

[0032] Finally, it should be noted that the driving cylinder 32, driving motor 44, etc. in this embodiment, the electronic components in the above components are all general standard components or components known to those skilled in the art. Their structures and principles can be known by those skilled in the art through technical manuals or obtained through conventional experimental methods.
