[0029] See also Figure 1-6As shown, a high-efficiency injection mold for producing automotive rubber and plastic parts includes: an upper mold base 1, a rotating mechanism is arranged inside the upper mold base 1, and a compacting assembly is arranged on the inner side of the rotating mechanism; the compacting assembly includes a mounting ring 6, a top plate 18, a limit seat 19, a conveying cylinder 20, a discharge pipe 21, a pressure valve 22, a stirring assembly and a solid stirring assembly, the top plate 18 is fixedly mounted on the top of the conveying cylinder 20, the limit seat 19 is fixedly sleeved on the outside of the conveying cylinder 20, the stirring assembly includes a discharge cylinder 23, an opening 24 and a stirring blade 25, the discharge cylinder 23 is fixedly mounted on the bottom of the top plate 18, the side wall of the discharge cylinder 23 is provided with an opening 24 for discharging, the stirring blade 25 is fixedly mounted on the outer wall of the discharge cylinder 23, the mounting ring 6 is movably sleeved on the outside of the bottom end of the conveying cylinder 20, the discharge pipe 21 is arranged at the bottom of the solid stirring assembly, and the pressure valve 22 is arranged inside the discharge pipe 21.
[0030] Specifically, by providing a compacting component, when in use, the top plate 18 can be driven by a rotating mechanism to rotate reciprocatingly and limitedly, so that when the injection plastic is being conveyed, the stirring component and the solid stirring component can be used to stir or compact the injection plastic. When the injection plastic is conveyed to the discharge barrel 23 for discharge, the top plate 18 can drive the stirring blades 25 to stir the injection plastic, so that the distribution of the injection plastic is more uniform and reliable, thereby improving the injection molding effect and injection molding quality, and cooperating with the solid stirring component, it is not easy for bubbles to appear in the injection plastic during transportation, so that the injection plastic can be continuously and sustainably transported, so that the appearance of the product is not easy to be damaged or the local quality is relatively thin, which is beneficial to the injection molding of automotive rubber and plastic parts, and the defective rate is greatly reduced, which is beneficial to the mass production of automotive rubber and plastic parts.
[0031] In this embodiment, nitrogen springs 2 and positioning columns 3 are provided at the bottom of the upper mold base 1. Multiple groups of nitrogen springs 2 and positioning columns 3 are provided and are evenly distributed in a circular array with the vertical center line of the upper mold base 1 as the center. The nitrogen springs 2 and positioning columns 3 are distributed at intervals.
[0032] Specifically, when in use, the positioning column 3 can make the cooperation between the upper and lower molds more precise. At the same time, the use of the nitrogen spring 2 can increase the life of the mold and simplify the mold design. The nitrogen spring 2 is small in size (can save mold space), has a large elastic force (can reduce the number of springs), and has a long life (can reduce the number of mold maintenance times), and is easy to use. The device is connected to an external power supply to provide power for the device, and the device is connected to an external controller. The controller is electrically connected to the motor 8. The device is connected to a matching lower mold base and a lower mold. A matching upper mold can also be provided at the bottom of the limit ring 4. A driving assembly should also be provided on the top of the upper mold base 1 so that the upper mold base 1 can move back and forth. The motor 8 uses a servo motor.
[0033] The solid stirring assembly includes a plug ring 26, a needle 27, a return spring 28, a connecting plate 29, a telescopic frame 30, a cylinder 31, a spiral blade 32, a through hole 33, a circular plate 36, a rotating column 34 and a limit block 35.

[0034] Specifically, during use, when the pressurized injection plastic enters the inner side of the cylinder 31, its impact force causes the connecting plate 29 to move downward, thereby compressing the reset spring 28. When the telescopic frame 30 and the reset spring 28 are compressed to a certain value, the reset spring 28 will rebound to a certain extent, thereby causing the connecting plate 29 to drive the puncture needle 27 to move back and forth, thereby performing a solid operation on the injection plastic, making it difficult for bubbles to form inside the injection plastic, thereby reducing the probability of bubble generation. At the same time, when the liquid injection plastic flows to the inner side of the cylinder 31, the liquid injection plastic can, to a certain extent, cause the rotating column 34 to drive the spiral blade 32 to rotate during the flow, thereby stirring the injection plastic again, thereby making the flow effect of the injection plastic better.
[0035] The rotating mechanism includes a limit ring 4, a mounting seat 5, a support plate 7, a motor 8, a driving gear 9, a rotating shaft 10, a gear ring 11, a fixing column 12, a connecting rod 13, a mounting column 14, an injection tube 15, a feeding tube 16 and a conveying tube 17. The limit ring 4 is fixedly mounted on the bottom of the upper mold base 1, the mounting seat 5 is fixedly embedded on the inner wall of the upper mold base 1, the gear ring 11 is movably sleeved on the outside of the mounting seat 5, the support plate 7 is fixedly mounted on the outer wall of the upper mold base 1, the motor 8 is fixedly mounted on the bottom of the support plate 7, the output end of the motor 8 is fixedly connected to the rotating shaft 10, the driving gear 9 is fixedly sleeved on the top outside of the rotating shaft 10, the driving gear 9 is meshed and installed with the gear ring 11, and the conveying tube 17 is fixedly mounted on the upper mold base 11. The bottom end is connected with the injection tube 15, one end of the feed tube 16 is connected with the injection tube 15, and the other end of the feed tube 16 is connected with the discharge cylinder 23 at the bottom of the top plate 18. A fixed column 12 is arranged on the top of the gear ring 11, and a mounting column 14 is arranged on the top of the top plate 18. The limit seat 19 is movably mounted inside the mounting seat 5, and the mounting ring 6 is fixedly mounted inside the mounting seat 5. One end of a group of connecting rods 13 is movably sleeved on the outside of the fixed column 12, and the other end of the connecting rod 13 is movably sleeved on the outside of a group of mounting columns 14, one end of the remaining connecting rods 13 is movably sleeved on the outside of the remaining mounting columns 14, and the other end of the connecting rod 13 is movably sleeved on the outside of the adjacent mounting columns 14.
[0036] Specifically, when in use, turn on the switch of the motor 8, so that the rotating shaft 10 drives the driving gear 9 to rotate, and then through the gear meshing, the gear ring 11 reciprocates around the mounting base 5, and then the connecting rod 13 drives the outermost top plate 18 to rotate, and then drives the remaining connecting rods 13 to rotate, so that all the top plates 18 can rotate reciprocatingly, so that the stirring mechanism can rotate, and the injection plastic has stronger fluidity, and the injection plastic flows into the conveying cylinder 20 through the conveying pipe 17, the feeding pipe 16 and the injection molding pipe 15.
[0037] In summary, compared with the prior art, the high-efficiency injection mold for the production of automotive rubber and plastic parts has at least the following beneficial effects: by providing a compacting component, when in use, the top plate 18 is driven by a rotating mechanism to rotate reciprocatingly and within a limited position, so that when the injection plastic is being conveyed, the stirring component and the solid stirring component are used to stir or compact the injection plastic. When the injection plastic is conveyed to the discharge barrel 23 for discharge, the top plate 18 can drive the stirring blades 25 to stir the injection plastic, so that the distribution of the injection plastic is more uniform and reliable, thereby improving the injection molding effect and injection molding quality, and in conjunction with the solid stirring component, it is not easy for bubbles to appear in the injection plastic during transportation, so that the injection plastic can be continuously and sustainably transported, so that the appearance of the product is not easy to be damaged or the local quality is relatively light and thin, which is beneficial to the injection molding of automotive rubber and plastic parts, and the defective rate is greatly reduced, which is beneficial to the mass production of automotive rubber and plastic parts.
