Description

Technical Field

[0001] The present application relates to the technical field of injection molding machines, and in particular to an electric turntable injection molding machine and an injection molding process thereof. Background Art

[0002] An injection molding machine is a device used to make plastic products. It melts the plastic material by heating, then injects it into a mold, jets it under pressure, and finally obtains the desired plastic product.

[0003] The existing vertical turntable injection molding machine is generally provided with a rotating table, on which a plurality of injection molding stations are arranged, and molds are installed on the injection molding stations. When the vertical turntable injection molding machine is working, the inserts are installed in the molds, and the rotating driving member drives the rotating table to rotate, so that the molds move under the injection molding mechanism in turn. The injection molding machine heats the plastic, applies high pressure to the molten plastic, so that it is ejected and fills the mold cavity, completing the injection molding, and then manually taking out the completed injection molded inserts from the mold in turn, and then putting the inserts to be injected into the mold in turn.

[0004] However, in actual application, the temperature of molten plastic is very high. After the injection molding mechanism injects the molten material into the mold for molding, it needs to wait for a period of time before the demolding process can be carried out. Also, after the insert is demolded, it is necessary to replace it with a new insert for injection molding. The insert needs to be installed in the specified position of the mold, and not only the accurate installation position of the insert must be met, but also the stability of the installation of the insert must be determined. Therefore, for inserts with high quality requirements, auxiliary tools are required when installing the inserts, which causes the injection molding machine to stop running during the injection molding jet and insert installation process, resulting in a process time difference during the injection molding process. These time intervals will affect the production progress and efficiency, and the injection molding production efficiency is low. Summary of the invention

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] On the one hand, an embodiment of the present application discloses an electric turntable injection molding machine.

[0035] Example 1 Reference Figure 1 and Figure 2An electric turntable injection molding machine comprises a frame 1, a discharge port is arranged on one side of the frame 1; an injection molding mechanism 2 is arranged on the top of the frame 1, the injection molding mechanism 2 can be raised and lowered at the top of the frame 1, and the discharge port is located at the bottom of the injection molding mechanism 2; a rotating table 3 is arranged at the bottom of the injection molding mechanism 2, and the rotating table 3 is rotatably connected to the top of the frame 1; a rotating driving member is connected to the bottom of the frame 1, and the rotating driving member is used to drive the rotating table 3 to rotate at the top of the frame 1; a plurality of injection molding stations are arranged on the rotating table 3. In this embodiment, the number of injection molding stations is two, and the rotating table 3 is connected to the rotating table 3. The platform 3 is radially arranged, and one of the injection molding stations is located directly below the injection molding end of the injection molding mechanism 2; multiple molds 4 are matched and installed on the injection molding station. In this embodiment, the rotating drive member adopts a driving motor; a discharge mechanism 5 is used to discharge the mold 4 after injection molding from the discharge port of the frame 1; a conveying mechanism 6 is arranged at the discharge port and is used to convey the mold 4 that has been taken out; an air jet mechanism 7 is located at the discharge port and on the conveying line of the conveying mechanism 6, and is used to perform air jet cooling on the mold 4 and the injection molded product. In this embodiment, the rotating drive member adopts a driving motor.

[0036] When performing product injection molding, the plastic material is placed in the injection molding mechanism 2. The injection molding mechanism 2 heats the material into a molten state and then injects it into the molding mold 4 for injection molding. At the same time, the mold 4 with the insert installed is installed on an injection molding station far away from the bottom of the injection molding mechanism 2, thereby reducing the possibility of installing the insert after the injection molding is completed, so that the injection molding machine can operate stably and regularly. Furthermore, after the injection molded product is formed, the material is discharged through the discharging mechanism 5, and the mold 4 is moved to the injection molding station of the rotating table 3 away from the injection molding mechanism 2 at one end through the conveying mechanism 6. During the conveying process, the jet mechanism 7 jets to cool the mold 4 to facilitate the removal of the finished product from the mold 4 and improve the cooling efficiency. Subsequently, the insert is installed on the mold 4 and pre-installed. There is no need to wait for the mold 4 below the injection molding mechanism 2 to rotate to the end away from the injection molding mechanism 2 before installing the insert, thereby reducing the possibility of the injection molding machine being suspended due to the complexity and long time of the insert installation, thereby improving the injection molding efficiency.

[0037] The injection molding mechanism 2 includes a feeding component 21, an injection molding component 22, a lifting platform 23 and a lifting drive 24. The feeding component 21 is located at the top of the frame 1. The feeding component 21 is connected to the injection molding component 22. The injection molding component 22 is connected to the lifting platform 23. The injection end of the injection molding component 22 is inserted into the bottom of the lifting platform 23. The lifting drive 24 is fixed to the frame 1. The output end of the lifting drive 24 is connected to the lifting platform 23. The lifting drive 24 is used to drive the lifting platform 23 to move up and down. The injection molding station is located at the bottom of the injection molding component 22. In this embodiment, the lifting drive 24 adopts a hydraulic cylinder, and the lifting platform 23 is driven to move up and down by the hydraulic cylinder.

[0038] When injection molding is performed, the lifting drive 24 is started, and the lifting drive 24 drives the lifting platform 23 to descend, and the lifting platform 23 drives the injection molding component 22 to descend, thereby moving the injection molding component 22 to the mold 4 for injection molding. When the injection molding is completed, the injection molding component 22 rises under the action of the lifting drive 24, so that the finished product of the additional injection molding is moved out from the bottom of the injection molding component 22, and at the same time, the new mold 4 is moved to the bottom of the injection molding component 22 for injection molding, thereby improving the convenience of injection molding.

[0039] Reference Figure 3 The mold 4 includes a mounting seat 41, a bottom mold 42 and a die 43. There are two mounting seats 41, which are fixedly mounted on two injection molding stations respectively. The bottom mold 42 is detachably mounted on the mounting seat 41. The die 43 is fixedly connected to the bottom wall of the lifting platform 23. The output end of the injection molding component 22 penetrates through the bottom wall of the die 43. The injection molding component 22 is fixed to the die 43. When injection molding is performed, when the bottom mold 42 and the die 43 are fitted together, a closed injection molding cavity is formed between the bottom mold 42 and the die 43. The injection molding component 22 performs injection molding in the injection molding cavity, thereby realizing injection molding.

[0040] A plate 44 is installed on one side where the two mounting seats 41 are close to each other, which is used to position the bottom mold 42. When installing the bottom mold 42, the bottom mold 42 installed with the insert is placed on the mounting seat 41, and the bottom mold 42 is pushed so that the bottom mold 42 is embedded in the plate 44 from the opening of the plate 44, thereby positioning the bottom mold 42, improving the accuracy of the position of the bottom mold 42 installed on the mounting seat 41, and improving the speed of installation.

[0041] Refer to 3 and Figure 4In order to improve the unloading speed of the injection molded product, the mold 4 also includes an injection molded part 45 and a material ejecting part 46. The bottom wall of the die 43 is provided with an upper die groove 431, the top wall of the injection molded part 45 is provided with a lower die groove 451, the insert is installed in the lower die groove 451, the top wall of the bottom mold 42 is provided with an injection groove 432, the injection molded part 45 is embedded in the injection groove 432, when the injection molded part 45 is fitted with the die 43, the upper die groove 431 is connected with the lower die groove 451 The ejector 46 is located at the bottom of the injection molded part 45, and the ejector 46 is inserted and slidably connected to the injection molded part 45. The ejector 46 is slidably connected to the bottom mold 42. The ejector 46 is used to eject the injection molded product from the injection molded part 45. The ejector 46 is fixedly connected to the ejector spring 461, and one end of the ejector spring 461 away from the ejector 46 is connected to the injection molded part 45. In order to reduce the ejector when the injection molding assembly 22 is being injected, 46 may slide down, a limit piece 462 is provided at the bottom of the ejecting member 46, and the limit piece 462 is connected to the groove wall of the injection groove 432. The discharging mechanism 5 includes a clamping assembly 51, a movable guide rail 52 and a movable driving assembly 53. The clamping assembly 51 is used to clamp the bottom mold 42 and enable the ejecting member 46 to eject the injection molded product. The movable guide rail 52 is connected to the frame 1, and the clamping assembly 51 is slidably connected to the movable guide rail 52. The movable driving assembly 53 is connected to the frame 1, and the output end of the movable driving assembly 53 is connected to the clamping assembly 51. The movable driving assembly 53 is used to drive the clamping assembly 51 to move along the length direction of the movable guide rail 52. In this embodiment, the movable driving assembly 53 adopts a driving motor and a screw rod to make the clamping assembly 51 move in a directional manner. The driving motor and the screw rod are used to move the object. This is a prior art and will not be described in detail here.

[0042] When it is necessary to take out the finished injection molded product, the clamping assembly 51 is started, and the clamping assembly 51 clamps the bottom mold 42 to separate the bottom mold 42 from the mounting seat 41. At the same time, the clamping assembly 51 pushes the ejecting member 46, and the ejecting member 46 slides with the bottom mold 42. The ejecting member 46 ejects the finished injection molded product from the injection molded part 45, so that there is a gap between the finished injection molded product and the injection molded part 45. The moving drive assembly 53 is started, and the moving drive assembly 53 drives the clamping assembly 51 to move along the moving guide rail 52, thereby moving the bottom mold 42 to the discharge port, and the jet mechanism 7 cools down the finished injection molded product. At the same time, the ejected finished injection molded product increases the contact area with the air, further improves the cooling efficiency, and facilitates the removal of the finished injection molded product, thereby improving the injection molding efficiency.

[0043] Specifically, in this embodiment, in order to facilitate the clamping assembly 51 to clamp the bottom mold 42 off the mounting base 41 and avoid colliding with the lifting drive 24 during the movement, the clamping assembly 51 is pneumatically driven. A pneumatic drive system is used to make the clamping assembly 51 approach or move away from the bottom mold 42, and another pneumatic drive system is used to make the clamping assembly 51 clamp or lower the bottom mold 42.

[0044] The clamping assembly 51 is provided with two clamping clamps and two clamping ends which are symmetrically arranged. Clamping grooves for clamping by the clamping assembly 51 are provided on both sides of the bottom mold 42. The clamping grooves are arranged horizontally. When the clamping assembly 51 is in a state of clamping the bottom mold 42, the clamping clamps clamp the bottom mold 42. The clamping clamps abut against the bottom mold 42. The clamping ends abut against the groove walls of the clamping grooves. The clamping grooves are connected to the injection molding grooves 432. The bottom of the ejecting member 46 is located in the clamping direction of the clamping grooves. The mounting seat 41 is connected with a fixed driving member 47. The mounting seat 41 is provided with a fixed groove 471. The fixed groove 471 is connected to the injection molding groove 432. The mounting seat 41 is slidably connected with a fixing member 472. The fixing member 472 is inserted into the fixed groove 471. The output end of the fixed driving member 47 is connected to the fixing member 472 is connected, and fixed wings 473 are symmetrically arranged on both sides of the fixing member 472. The side of the fixing wing 473 away from the fixing member 472 is tightly pressed against the groove wall of the injection groove 432. A pushing block 474 is slidably connected in the injection groove 432. When the clamping assembly 51 clamps the bottom mold 42, the clamping assembly 51 pushes the ejecting member 46 so that the ejecting member 46 ejects the finished product out of the lower mold groove 451. Subsequently, the clamping assembly 51 continues to clamp, and the clamping end of the clamping assembly 51 pushes the pushing block 474 to move, so that the pushing block 474 moves toward the fixed wing 473, and then the fixed wing 473 is folded, so that the fixing member 472 is easily removed from the bottom mold 42, thereby realizing the separation of the bottom mold 42 and the mounting seat 41. In this example, the fixed driving member 47 adopts a cylinder.

[0045] After the clamping assembly 51 clamps the bottom mold 42 away from the mounting base 41, the moving driving assembly 53 drives the clamping assembly 51 to move along the length direction of the moving guide rail 52 until the bottom mold 42 is moved to the conveying mechanism 6. In this embodiment, the conveying mechanism 6 uses belt drive to convey the bottom mold 42, which is a prior art and will not be elaborated on here.

[0046] The jet mechanism 7 includes a cold air component, a hot air component and a waste heat recovery component. The output end of the cold air component faces the discharge port, and the cold air component is used to cool the injection molded product. The hot air component is arranged along the conveying direction of the conveying mechanism 6, and the output end of the hot air component faces the conveying mechanism 6. The waste heat recovery component is used to recover the waste heat generated by the injection molding component 22 and transport the waste heat to the hot air component.

[0047] The cold air component includes a folding piece 71, a one-way air inlet piece 711 and a one-way air outlet piece 712. The folding piece 71 is hollow. One end of the folding piece 71 is fixedly connected to the bottom wall of the lifting platform 23. The end of the folding piece 71 away from the lifting platform 23 is connected to the frame 1. The one-way air inlet piece 711 is fixedly connected to the folding piece 71. The one-way air inlet piece 711 is used to inflate the folding piece 71. The one-way air outlet piece 712 is fixedly connected to the folding piece 71. The one-way air outlet piece 712 is used to spray air to the folding piece 71. The output end of the one-way air outlet piece 712 faces the discharge port.

[0048] When the injection molding component 22 is raised or lowered, and the lifting platform 23 is rising, the gas enters the folding piece 71 from the one-way air inlet 711; when the lifting platform 23 is lowered, the folding piece 71 is folded, and the gas in the folding piece 71 is ejected from the one-way air outlet 712. At this time, under the action of the clamping component 51, the bottom mold 42 ejects the finished product from the lower mold groove 451, thereby increasing the area of ​​the finished product exposed to the air, and the gas in the folding piece 71 is sprayed toward the finished product, thereby achieving cooling of the injection molded product, improving cooling efficiency, and reducing energy consumption.

[0049] The hot air component includes an inflatable piece 72, an airbag 721 and a nozzle 722. The inflatable piece 72 is used to inflate the airbag 721. The airbag 721 is connected to the nozzle 722. The nozzle 722 faces the conveying mechanism 6 and is used to spray the gas in the airbag 721 to the bottom mold 42 on the conveying mechanism 6. The waste heat recovery component is used to recover the waste heat generated by the injection molding component 22 and transport the waste heat to the airbag 721.

[0050] The groove wall of the injection groove 432 is provided with a first connecting hole 73, and the die 43 is provided with a second connecting hole 731. When the die 43 is in contact with the bottom die 42, the first connecting hole 73 is connected to the second connecting hole 731. The waste heat recovery component includes an air suction piece 732 and an air suction pipe 733. The input end of the air suction pipe 733 is connected to the second connecting hole 731, and the output end of the air suction pipe 733 is connected to the air bag 721. The air suction piece is used to absorb the heat generated during injection molding and transmit it to the air bag 721 through the air suction pipe 733. In this embodiment, the air suction piece adopts a suction fan.

[0051] The implementation principle of an electric turntable injection molding machine in the embodiment of the present application is as follows: when performing injection molding, a bottom mold 42 with an insert installed is installed on the top of a mounting seat 41, and the rotating table 3 is rotated so that the bottom mold 42 is rotated to the bottom of the injection molding component 22 for injection molding operation. After the injection molding is completed, the clamping component 51 is started, the clamping component 51 clamps the bottom mold 42, and the finished product is ejected from the lower mold groove 451, and is moved to the position of the one-way air outlet member 712 under the action of the moving drive component 53 for cooling and material removal. The bottom mold 42 that has been taken and is empty is placed on the conveying mechanism 6. During the movement, the nozzle 722 sprays air toward the bottom mold 42 for preheating, and then the insert is installed, so that during the operation of the injection molding component 22, the insert can be installed and the bottom mold 42 can be installed, reducing the manual intervention of the rotating table 3 during rotation, and the finished product is clamped off the rotating table 3, so that the finished product is cooled and the material is removed outside the injection molding machine, reducing the possibility of the injection molding machine suspending operation, thereby improving the injection molding efficiency.

[0052] Example 2 Reference Figure 5 , which is different from Example 1, is that a plug-in unit 48 is inserted into the mounting seat 41, and an insertion drive member 481 is arranged in the plug-in unit 48, and the insertion drive member 481 is fixedly connected to the mounting seat 41, and a sliding member 483 is arranged in the plug-in unit 48, and the output end of the insertion drive member 481 is fixedly connected to the sliding member 483, and an inclined groove 482 is provided on one side of the plug-in unit 48, and the inclined groove 482 runs through the top wall of the plug-in unit 48, and a sliding rod 484 is slidably arranged in the inclined groove 482, and a hinge 485 is inserted into the end of the sliding member 483 away from the plug-in unit 48, and the hinge 485 is located at the top of the sliding member 483, and the sliding member 483 is hinged with a stabilizing wing 486 through a hinge 485, and the stabilizing wing 486 is generally F-shaped. The sliding rod 484 is used to push the head of the stabilizing wing 486 against the bottom mold 42, so that the mounting seat 41 and the bottom mold 42 are assembled. The tail of the stabilizing wing 486 is hinged to the sliding member 483 through the hinge 485, and a sliding groove is opened through the tail of the stabilizing wing 486. One end of the sliding rod 484 is located in the sliding groove. A connecting member 487 is inserted on one side of the sliding rod 484. The sliding rod 484 is slidably connected to the tail of the stabilizing wing 486 through the connecting member 487. In this embodiment, the inserted driving member 481 adopts a cylinder.

[0053] The implementation principle of an electric turntable injection molding machine in an embodiment of the present application is as follows: when installing the bottom mold 42 and the mounting seat 41, the insertion driving member 481 drives the pushing member to push the sliding member 483 to move along the insertion member 48, and the sliding rod 484 slides in the inclined groove 482, thereby causing the sliding rod 484 to slide in the transverse groove, so that the stabilizing wing 486 abuts against the bottom mold 42, and the bottom mold 42 and the mounting seat 41 are assembled, thereby improving the installation speed of the bottom mold 42 and the mounting seat 41.

[0054] On the other hand, an embodiment of the present application also discloses an injection molding process of an electric turntable injection molding machine.

[0055] S1: Install the insert on the bottom mold 42; S2: starting the rotary drive member, which drives the rotary table 3 to rotate, and rotates the bottom mold 42 with the insert installed to the bottom of the injection molding component 22; S3: Start the lifting drive member 24, the lifting drive member 24 drives the injection molding component 22 to descend, so that the injection molding component 22 is lowered, and the injection molding component 22 is injected into the injection molding cavity to achieve injection molding; S4: the injection molding assembly 22 rises, and the clamping assembly 51 clamps the bottom mold 42 after injection molding away from the injection molding station, and the bottom mold 42 is discharged from the discharge port and pushed to the conveying mechanism 6; S5: The gas ejected by the jet mechanism 7 is ejected toward the bottom mold 42 located on the conveying mechanism 6, so as to cool the injection molded product and blow the debris away from the injection molded product, and the injection molded product is taken out. At the same time, steps S1 to S4 are repeated.

[0056] Specifically, step s4 is as follows: the clamping assembly 51 clamps the bottom mold 42 away from the mounting seat 41, and at the same time, the clamping end of the clamping assembly 51 pushes the ejecting piece 46, so that the ejecting piece 46 ejects the finished product from the lower mold groove 451. Under the action of the moving drive assembly 53, the bottom mold 42 moves to the cold air assembly to cool the finished product, and then moves to the conveying mechanism 6.

[0057] The implementation principle of the injection molding process of an electric turntable injection molding machine in the embodiment of the present application is as follows: when performing injection molding, a bottom mold 42 with an insert installed is installed on the rotating table 3, and the rotating driving member drives the rotating table 3 to rotate, and the bottom mold 42 is moved to the bottom of the injection molding component 22 for injection molding. After the injection molding is completed, the clamping component 51 clamps the bottom mold 42 away from the mounting seat 41, so that the finished product can be taken out and cooled outside the rotating table 3. At the same time, when performing injection molding, the bottom mold 42 with the insert pre-installed can be quickly installed on the mounting seat 41, reducing the possibility of the rotating table 3 suspending rotation due to the complexity of the installation of the insert. In the process of injection molding, cooling, taking out, and placing the insert, the insert can be pre-installed, and the cooling component can cool the injection molded product, thereby shortening the waiting time, so that the injection molding operation of the injection molding machine can be carried out stably and continuously, reducing manual intervention in the injection molding machine during operation, thereby improving the injection molding efficiency.

[0058] The above are all preferred embodiments of the present application. The embodiments are only explanations of the present application and do not limit the protection scope of the present application in turn. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
