Description

Technical Field

[0001] The present invention relates to the technical field of plastic molding equipment, specifically to a high-precision integrated molding equipment for automotive plastic parts and a composite processing technology. Background Art

[0002] Automotive plastic parts refer to product accessories made of plastic on automobiles, which are widely used in various parts of automobiles. The high-precision integrated molding equipment for automotive plastic parts can realize the one-time processing of plastic raw materials into high-precision and high-quality automotive plastic parts, and complete multiple production processes at the same time. It has the characteristics of high efficiency, energy saving, and precision. By heating plastic particles to a molten state and then injecting the molten plastic into the mold cavity under high pressure, after cooling and solidification, the required plastic parts are formed, which can strictly control the dimensional accuracy and surface quality of the plastic parts and meet the high-precision requirements of the automotive industry for plastic parts.

[0003] In the injection process step, it is necessary to precisely control the injection pressure to ensure that the plastic melt can fill the mold cavity and obtain good molding quality. However, in the process of mold opening and demolding of the existing injection mechanism, in order to prevent the continuous output of raw materials, the driving motor will be stopped. Frequent starting and stopping of the driving motor will damage the motor life and cause excessive heat, reducing production efficiency and increasing maintenance costs. Or the output valve is closed. At this time, the pressure in the injection mechanism is uneven due to continuous driving, which is easy to cause the injection pipeline to burst. And the existing process requires demolding the mold after mold opening. However, since the demolding rod also contacts during mold shaping, the mold is easily adhered to the demolding rod and moves synchronously with the demolding rod, unable to complete demolding, resulting in reduced production efficiency.

[0013] The present invention provides a high-precision integrated molding device and a composite processing technology for automotive plastic parts. Compared with the prior art, it has the following beneficial effects:

[0014] (1) In the high-precision integrated molding device and composite processing technology for automotive plastic parts, during the mold opening process by the demolding mechanism, the guiding threaded column drives the rotating sleeve to rotate, thereby driving the demolding rod to reciprocate left and right. Moreover, due to the difference in the number of demolding rods and the jacking ribs, multiple demolding rods are not in the same plane simultaneously, and the finished product is ejected in a staggered manner, which can effectively prevent the finished product from adhering to the demolding rod, greatly improving the demolding success rate, enabling effective demolding, improving production efficiency, and reducing production stagnation and defective product rate caused by demolding problems.

[0015] (2) In the high-precision integrated molding device and composite processing technology for automotive plastic parts, through a number of reflux outlets opened between the rear pitches of the feeding screw, in cooperation with the reflux inlet of the non-return head and the internal reflux channel, it is possible to balance the pressure inside the feeding barrel while the driving motor is not turned off, overcoming the problem that when the existing injection mechanism closes the valve, uneven pressure is caused by continuous driving, which easily leads to the rupture of the injection pipeline. And through the reflux outlet and the reflux inlet, the raw material can be continuously conveyed, avoiding raw material precipitation, maintaining its fluidity, reducing equipment failures and maintenance costs, and enhancing the continuity and stability of production.

[0016] (3) In the high-precision integrated molding device and composite processing technology for automotive plastic parts, through the stop valve assembly, during the mold closing process, the pressing of the moving template against the fixed template synchronously presses the stop valve assembly to open the injection channel, enabling the melted raw material to enter the mold; when the mold is opened, the stop valve assembly can adaptively close the injection channel to prevent the remaining material inside the injection channel from flowing out and overflowing, indirectly improving production efficiency, contributing to enhancing product quality, and avoiding the influence of material overflow on the molding effect of plastic parts.

[0027] The technical solutions in the embodiments of the present invention are clearly and completely described. 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 efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-9 , an embodiment of the present invention provides a technical solution: a high-precision integrated forming device for automotive plastic parts, including a machine table 6, an injection mechanism 5 is arranged on the right side of the top of the machine table 6, a hopper 4 is arranged above the injection mechanism 5, a mold clamping mechanism 1 is arranged on the left side of the top of the machine table 6, a fixed template 2 is arranged at the right end of the mold clamping mechanism 1, a mold outlet 7 is arranged below the fixed template 2 on the top of the machine table 6, and an operation indicator light 3 is arranged in the middle of the top of the machine table 6.

[0029] During operation, first add raw materials into the hopper 4, and then start the equipment. At this time, the injection mechanism 5 conveys the raw materials towards the fixed template 2. During the conveying process, the raw materials are melted by heating. At the same time, the mold clamping mechanism 1 is closely attached to the fixed template 2. The melted raw materials enter the mold for integrated shaping. After shaping is completed, the mold is opened, and the mold clamping mechanism 1 performs a demolding operation on the finished product, causing the finished product to fall into the mold outlet 7. During the entire process, the operation indicator light 3 can display the operating status of the equipment.

[0030] Among them, the operation indicator light 3 and the hopper 4 are both prior arts and will not be explained here.

[0031] Please refer to Figure 2 , the mold clamping mechanism 1 includes a fixed plate 12. The bottom end of the fixed plate 12 is fixedly connected to the left side of the top of the machine table 6. Four outer corners at the right end of the fixed plate 12 are fixedly connected with guiding rods 15. The right ends of the guiding rods 15 extend into the fixed template 2. In the middle of the left end of the fixed plate 12, there is a mold clamping cylinder 11. The output shaft of the mold clamping cylinder 11 extends to the outside of the right end of the fixed plate 12. A moving template 14 is sleeved on the outer surfaces of the four guiding rods 15. On the upper and lower sides of the left end of the moving template 14, there are connecting linkages 13 fixedly connected. The left ends of the connecting linkages 13 are fixedly connected to the right end of the fixed plate 12. In the middle of the opposite sides of the two connecting linkages 13, there is a right-angle joint sleeve 18 rotatably connected. The right-angle joint sleeve 18 is sleeved on the outer surfaces of the four guiding rods 15. The middle of the left end of the right-angle joint sleeve 18 is fixedly connected to the right end of the output shaft of the mold clamping cylinder 11. In the middle of the left end of the moving template 14, there is a demolding mechanism 17 fixedly connected. The left end of the demolding mechanism 17 is fixedly connected to the middle of the right end of the right-angle joint sleeve 18. Cooling connection ports 16 are fixedly connected to the rear ends of the moving template 14 and the fixed template 2.

[0032] During mold clamping, the mold clamping cylinder 11 is started, and its output shaft extends to push the right-angle joint sleeve 18 to move rightward along the guiding rods 15. Since the right-angle joint sleeve 18 is connected to the moving template 14 through the connecting linkages 13, the moving template 14 is driven by the connecting linkages 13 and also moves rightward along the guiding rods 15 synchronously until the moving template 14 is closely attached to the fixed template 2. At this time, the mold is closed, creating space for raw material injection and plastic part shaping. During mold opening, the output shaft of the mold clamping cylinder 11 retracts, pulling the right-angle joint sleeve 18 to move leftward, and then driving the moving template 14 to retract leftward along the guiding rods 15 to open the mold. During the entire process, the cooling connection ports 16 at the rear ends of the moving template 14 and the fixed template 2 can be connected to a cooling device to cool the plastic parts in the mold, accelerating shaping. The guiding rods 15 play a guiding role to ensure the stable movement of the moving template 14 and ensure the accurate performance of mold clamping and mold opening actions. During the mold opening process, the demolding mechanism 17 can perform a demolding operation on the finished product.

[0033] Among them, the mold clamping cylinder 11 drives the right-angle joint sleeve 18, and drives the moving template 14 to perform opening and closing operations through the connecting linkages 13, which are all prior arts and will not be explained here.

[0034] Please refer to Figures 3-4 , the demolding mechanism 17 includes a guiding threaded post 171. The left end of the guiding threaded post 171 is fixedly connected to the middle part of the right end of a right-angle sleeve 18. A rotating sleeve 174 is threadedly connected to the outer surface of the guiding threaded post 171. The outer surface of the rotating sleeve 174 is rotatably connected to a support plate 173. Two upper and lower parallel support linkage columns 172 penetrate through the front and rear sides of the support plate 173 and are slidably connected. The right end of the support linkage column 172 is fixedly connected to the left end of the moving template 14. The right end of the rotating sleeve 174 is fixedly connected to a rotating disk 175. Three wavy lifting ribs 176 are fixedly connected to the right end of the rotating disk 175. The three lifting ribs 176 are circularly arranged with the center of the rotating disk 175 as the center. Four connecting seats 178 are arranged on the right side of the lifting ribs 176. The four connecting seats 178 are square. A transmission ball 177 is rotatably connected to the left end of the connecting seat 178. The transmission ball 177 is in close contact with the right side of the lifting ribs 176 and the rotating disk 175. The middle part of the right end of the connecting seat 178 is fixedly connected to a demolding rod 1710. The right end of the demolding rod 1710 penetrates through the moving template 14 from left to right. The outer side of the right end of the connecting seat 178 is fixedly connected to a return spring 179. The right end of the return spring 179 is fixedly connected to the left end of the moving template 14.

[0035] During the mold opening process, as the moving template 14 separates from the fixed template 2, the demolding mechanism 17 and the moving template 14 move synchronously to the left. Due to the folding effect of the linkage connecting rod 13, the moving speed of the moving template 14 driving the support plate 173 and the rotating sleeve 174 is faster than that of the right-angle sleeve 18. When the rotating sleeve 174 moves on the outer surface of the guiding threaded post 171, it will rotate, causing the moving to drive the rotating disk 175 to rotate, and the lifting ribs 176 will rotate accordingly. The lifting ribs 176 contact and push the transmission ball 177, and the transmission ball 177 further pushes the connecting seat 178. The connecting seat 178 drives the demolding rod 1710 to extend to the right against the elastic force of the return spring 179, ejecting the molded plastic part from between the moving template 14 and the fixed template 2 to complete the demolding action. The cooperation of the wavy lifting ribs 176 and the return spring 179 enables the demolding rod 1710 to reciprocate, and the four demolding rods 1710 will not be in the same plane at the same time, preventing the adhesion of the finished product to the demolding rod 1710.

[0036] Please refer to Figure 5 , the injection mechanism 5 includes a transmission injection seat 52. A driving motor 53 is arranged at the right end of the transmission injection seat 52. The top end of the transmission injection seat 52 is fixedly connected to the bottom end of the hopper 4. The transmission injection seat 52 and the bottom end of the driving motor 53 are both fixedly connected to the top end of the machine table 6. The left end of the transmission injection seat 52 is fixedly connected to an injection barrel 51. The left end of the injection barrel 51 extends into the fixed template 2.

[0037] After the device is started, the driving motor 53 begins to operate, providing power for the entire injection process. The plastic raw materials in the hopper 4 fall into the transmission injection seat 52 by their own gravity, and then enter the connected injection barrel 51. Driven by the driving motor 53, the injection barrel 51 starts to work, transporting the raw materials towards the fixed template 2. During the transportation process, the raw materials are gradually pushed to the left end of the injection barrel 51 and finally injected into the mold cavity through the port extending into the fixed template 2, providing a material basis for the formation of plastic parts until the injection molding task is completed and waiting for the plastic parts to cool and solidify.

[0038] Both the driving motor 53 and the transmission injection seat 52 are prior arts and will not be explained here.

[0039] Please refer to Figure 6 , the fixed template 2 includes a template main body 21. The bottom end of the template main body 21 is fixedly connected to the top end of the machine table 6. An injection runner 23 is vertically penetrated through the middle of the template main body 21. A flow stop valve assembly 22 is arranged above the injection runner 23 inside the template main body 21. The injection runner 23 is internally communicated with the injection nozzle 511.

[0040] When the injection mechanism 5 starts to transport the melted raw materials to the fixed template 2, the raw materials will flow into the connected injection runner 23. During the mold closing stage, the moving template 14 gradually approaches and presses against the fixed template 2, which will trigger the flow stop valve assembly 22 to open the injection runner 23, allowing the raw materials to smoothly pass through the injection runner 23 and enter the mold cavity between the moving template 14 and the fixed template 2 for the integrated shaping and molding of plastic parts.

[0041] Please refer to Figures 5-7 , the injection barrel 51 includes a material conveying barrel 513. The right end of the material conveying barrel 513 is fixedly connected to the left end of the transmission injection seat 52. The material conveying barrel 513 is communicated with the hopper 4 through the transmission injection seat 52. The left end of the material conveying barrel 513 is fixedly connected with an injection nozzle 511, and the left end of the injection nozzle 511 extends into the fixed template 2. A plurality of heating sleeves 512 are fixedly connected to the outer surface of the material conveying barrel 513. A material conveying screw 514 is rotatably connected inside the material conveying barrel 513. The right end of the material conveying screw 514 is fixedly connected to the left end of the output shaft of the driving motor 53. The material conveying screw 514 is fixedly connected with a non-return head. A plurality of reflux outlets 515 are arranged between the pitches at the rear side of the material conveying screw 514. A reflux inlet 516 is vertically penetrated through the non-return head. A reflux channel 517 is arranged inside the material conveying screw 514. The reflux inlet 516 is communicated with the plurality of reflux outlets 515 through the reflux channel 517.

[0042] After the device is started, the plastic raw materials in the hopper 4 enter the feeding barrel 513 through the driving injection seat 52. The driving motor 53 drives the feeding screw 514 to rotate. During the rotation of the feeding screw 514, the raw materials are pushed to move leftward along the feeding barrel 513. During the movement, the heating sleeve 512 heats the raw materials, gradually melting them into plastic melt. Under the continuous push of the feeding screw 514, the plastic melt is injected into the mold cavity inside the fixed template 2 through the injection nozzle 511. When the valve is closed, the continuous output of the feeding screw 514 will cause the plastic melt to flow back from the reflux inlet 516 of the check head through the reflux channel 517 to the reflux outlet 515 under pressure. Such a cycle ensures stable raw material transportation and pressure balance, guarantees the smooth progress of the injection molding process, and maintains its fluidity.

[0043] Please refer to Figures 8-9 , the stop valve assembly 22 includes a stop valve core 225. The diameter of the stop valve core 225 is larger than that of the injection runner 23. The stop valve core 225 is slidably connected up and down inside the template body 21. The stop valve core 225 can block the injection runner 23. A counterweight 224 is fixedly connected to the top end of the stop valve core 225. A linkage rod 223 is rotatably connected to the top end of the counterweight 224. One end of the linkage rod 223 away from the counterweight 224 is rotatably connected to a locking slider 226. The locking slider 226 is horizontally slidably connected inside the template body 21. A plurality of support springs 227 are fixedly connected to the right end of the locking slider 226. The right ends of the support springs 227 are fixedly connected inside the template body 21. Two inclined surfaces are provided at the outer lower corner on the left end of the locking slider 226. The two inclined surfaces are respectively distributed on the front and rear sides of the linkage rod 223. An L-shaped trigger lever 222 is in contact with the inclined surface of the locking slider 226. The trigger lever 222 is rotatably connected inside the template body 21. A pressing rod 221 is provided on the left side of the trigger lever 222. The outer surface of the pressing rod 221 is slidably connected inside the template body 21. The left end of the pressing rod 221 extends to the inside and outside of the left end of the template body 21.

[0044] When the mold is closed, the moving platen 14 gradually approaches the fixed platen 2 and exerts pressure on it. The pressing rod 221 on the fixed platen 2 is pressed and moves to the right, pushing the L-shaped trigger lever 222 to rotate. After the trigger lever 222 rotates, its right end rises, pushing the locking slider 226 to slide to the right, compressing the support spring 227. The movement of the locking slider 226 drives the counterweight 224 and the flow-stop valve core 225 to lift through the linkage rod 223, so that the flow-stop valve core 225 no longer blocks the injection runner 23, and the injection runner 23 is opened. The melted raw material can smoothly enter the mold cavity from the injection nozzle 511 for molding. When the mold is opened, the moving platen 14 is separated from the fixed platen 2, the pressing rod 221 is no longer pressed, the support spring 227 restores its deformation, and pushes the locking slider 226 to slide to the left. The locking slider 226 drives the counterweight 224 and the flow-stop valve core 225 to slide downward through the linkage rod 223, and the flow-stop valve core 225 blocks the injection runner 23 again, preventing the remaining material inside the injection runner 23 from flowing out and overflowing, ensuring the normal operation of the equipment and the molding quality of plastic parts.

[0045] The composite processing technology of the high-precision integrated molding equipment for automotive plastic parts includes the following steps:

[0046] Please refer to Figures 1-9 , when working,

[0047] First, add plastic raw materials into the hopper 4. After starting the equipment, the driving motor 53 operates, driving the feeding screw 514 of the injection barrel 51 to rotate. The raw materials in the hopper 4 enter the feeding barrel 513 through the transmission injection seat 52 and are melted under the action of the heating sleeve 512. The plastic melt is conveyed to the fixed platen 2 through the injection nozzle 511. The clamping cylinder 11 is started, pushing the right-angle adapter sleeve 18, driving the moving platen 14 to move to the right along the directional guide rod 15 and closely adhere to the fixed platen 2. Press the flow-stop valve assembly 22 to open the injection runner 23, and the raw materials enter the mold for integrated shaping and molding. The cooling connection port 16 is connected to the cooling device to accelerate the molding. After shaping, the mold is opened, the clamping cylinder 11 retracts, the moving platen 14 moves to the left, and the guiding threaded column 171 of the demolding mechanism 17 drives the rotating adapter sleeve 174, driving the demolding rod 1710 to eject the finished product, which falls into the mold outlet 7.
