Description

Technical Field

[0001] This invention relates to the field of injection molding technology and equipment, and in particular to an injection molding machine for hybrid insulators. Background Technology

[0002] Insulators are essential electrical devices widely used in power systems to support and insulate critical components such as conductors and wires. With the rapid development of power systems and the ever-increasing performance requirements of insulators, traditional insulator manufacturing processes are no longer sufficient to meet modern production demands. In particular, the single processing station, complex operation, and low production efficiency in injection molding have become bottlenecks restricting the development of the insulator manufacturing industry.

[0003] Existing insulator injection molding machines typically employ a single-station design, requiring frequent manual intervention during injection, mold closing, and mold opening processes. This results in low production efficiency and difficulty in guaranteeing product quality. Furthermore, the control systems of these machines lack a high level of intelligence, making it difficult to achieve precise process control and automated operation.

[0004] Therefore, developing injection molding machines with high production efficiency, high-quality products, simplified operation processes, and high levels of intelligence can meet the high standards required by modern power systems for the production and application of insulators. Summary of the Invention

[0005] The purpose of this invention is to provide a hybrid insulator injection molding machine, thereby simplifying the operation process and automating it.

[0006] This invention provides a hybrid insulator injection molding machine, comprising a base, and further comprising a fork-plate type mold moving and lifting mechanism, an adjustable injection system, an opening and closing mechanism, a mold moving and lifting mechanism, and an electrical control system fixed on the base. The fork-plate type mold moving and lifting mechanism has two guide rails symmetrically mounted on its intermediate frame plate. A screw is mounted in the middle of the two guide rails using a pair of bearing seats. A reduction motor and a drive gear are mounted on the base plate of the fork-plate type mold moving and lifting mechanism. A driven gear is mounted on one end of the screw and meshes with the drive gear. A hydraulic cylinder is fixed to the guide plate and moves horizontally with the two guide rails. The mold moving fork is fixed to a support plate. Two linear guide rails on the mold moving and lifting mechanism are symmetrically distributed and fixed on both sides of the frame. Four guide rods are symmetrically distributed on the frame. The lifting plate has multiple through holes that mate with the four guide rods. The hydraulic cylinder is fixed to the base plate of the frame.

[0007] The above technical solution converts the driving force into a horizontal force on the mold-shifting fork plate via gears and screws. The driving force from the hydraulic cylinder on the guide plate acting on the support plate is then converted into a vertical force on the mold-shifting fork plate, giving it two degrees of freedom in both the vertical and horizontal directions. This facilitates the mold-shifting and lifting function of the forming mold. Furthermore, the two linear guide rails of the mold-shifting lifting mechanism are symmetrically distributed on both sides of the frame and connected by screws, facilitating the horizontal movement of the forming mold placed on the linear guide rails. Four guide rods are symmetrically distributed on the frame, and four through holes are provided on the lifting plate to accommodate the four guide rods, ensuring stable vertical movement. The hydraulic cylinder is fixed to the base plate of the frame via screws, providing a vertical driving force to the support plate.

[0008] Optionally, the adjustable injection system is located behind the hydraulic clamping mechanism and fixed above the support frame.

[0009] The above technical solution is used to inject plasticized material into the mold cavity through the runner plate for the injection process.

[0010] Optionally, the hydraulic mold clamping mechanism is located at the center of both machine frames. The hydraulic mold clamping machine includes a hydraulic cylinder, a lower mold base, a lower heating plate, an upper mold base, an upper heating plate, and a Green column. The hydraulic cylinder is located at the bottom of the lower mold base, the lower heating plate is located on the top surface of the upper mold base, and the upper heating plate is located on the bottom surface of the upper mold base.

[0011] Using the above technical solution, the hydraulic cylinder in the hydraulic mold closing mechanism provides the mold closing driving force to lift the lower mold base, the lower heating plate on the lower mold base, and the forming mold upward to the mold closing position to carry out the mold closing process.

[0012] Optionally, the four symmetrically distributed Green columns are fixed on the base, the upper mold base is fixed above the Green columns by a threaded connection, and the four through holes on the lower mold base are clearance fit with the Green columns.

[0013] By adopting the above technical solution, it can be ensured that the lower mold base is fixed by horizontal displacement through multiple Green Pillars during the mold closing process, thereby improving the lifting stability of the lower mold base.

[0014] Optionally, the lower heating plate has two symmetrically distributed mating grooves for mating with the mold-moving fork plate in the fork plate type mold-moving lifting mechanism.

[0015] The above technical solution is used in conjunction with the mold-moving fork plate in the fork plate type mold-moving lifting mechanism, so that the mold-moving fork plate can pass through the lower heating plate to reach the bottom of the forming mold, and under the driving force of the hydraulic cylinder in the fork plate type mold-moving lifting mechanism, the mold-moving fork plate and the forming mold are lifted upward to the horizontal straight direction where they are separated from the lower heating plate and reach the opening and closing position.

[0016] Optionally, the opening and closing mechanism is fixed to the upper end of the fork-plate type mold moving and lifting mechanism by screws, and includes a clamping jaw fixing platform, a mold opening cylinder, an opening and closing jaw, and a jaw mating block. The mold opening cylinder and the opening and closing jaw are assembled on the clamping jaw fixing platform, and the mold opening cylinder is located on both sides of the opening and closing jaw.

[0017] By adopting the above technical solution, the opening cylinder in the opening and closing mechanism provides driving force to the opening and closing claws on both sides, which pulls the pair of laterally moving slides on the forming mold to the left and right when they reach the opening and closing position, thus completing the opening and closing process of the forming mold and exposing the formed product in the forming mold, which facilitates the subsequent mold removal, mold cleaning and material loading processes.

[0018] Optionally, the mold moving and lifting mechanism is located on one side of the fork-plate type mold moving and lifting mechanism. The mold moving and lifting mechanism includes a linear guide rail, a hydraulic cylinder, and a lifting plate. The hydraulic cylinder is located at the bottom of the lifting plate, and the linear guide rail is located at the bottom of the forming mold.

[0019] Using the above technical solution, the molding die that has completed the opening and closing process is moved to the mold removal position by the linear guide rail in the mold moving and lifting mechanism. The hydraulic cylinder of the mold moving and lifting mechanism provides vertical driving force to the lifting plate, which vertically lifts and lowers the molding die to the optimal mold removal position set by the electronic control system, and performs the mold removal, mold cleaning and material loading process.

[0020] Optionally, the electrical control system includes a power control unit, a human-machine interface unit, and a rotating bracket. The human-machine interface unit and the rotating bracket are fixed on the upper mold base of the hydraulic mold closing mechanism, and the power control unit is located behind the support frame of the adjustable injection system.

[0021] By adopting the above technical solution, the operating status of each mechanism can be monitored and controlled in real time, ensuring the intelligent operation of the entire production process. Operators can conveniently set parameters and monitor equipment through the human-machine interface, improving the transparency and controllability of the production process. The mold-moving and lifting mechanism moves the mold that has completed the opening and closing process to the mold-removing position via linear guide rails, and provides vertical driving force through hydraulic cylinders to raise and lower the mold to the optimal mold-removing position set by the electronic control system. This design not only improves the comfort and safety of operators, but also significantly reduces labor intensity and further improves work efficiency. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by those skilled in the art. The terms "comprising" and similar expressions used herein mean that the element or object preceding the word covers the element or object listed after the word and its equivalents, but does not exclude other elements or objects.

[0031] This invention provides a hybrid insulator injection molding machine, characterized by comprising a base 22, and further comprising a fork-plate type mold moving and lifting mechanism 3, an adjustable injection system 1, an opening and closing mechanism 4, a mold moving and lifting mechanism 5, and an electrical control system 6 fixed on the base 22. Two guide rails 37 of the fork-plate type mold moving and lifting mechanism 3 are symmetrically mounted on the intermediate frame plate of the fork-plate type mold moving and lifting mechanism 3. The screw 35 is mounted in the middle position of the two guide rails 37 by a pair of bearing seats 34. A reduction motor 31 and a drive gear 32 are mounted on the fork-plate type mold moving and lifting mechanism. On the base plate of structure 3, the driven gear 32 is installed at one end of the screw 35 and meshes with the driving gear 32. The hydraulic cylinder 39 is fixed on the guide plate 36 and moves horizontally with the two guide rails 37. The mold moving fork plate 3-10 is fixed on the support plate 38. The two linear guide rails 54 on the mold moving lifting mechanism 5 are symmetrically distributed and fixed on both sides of the frame 51. The four guide rods 52 are symmetrically distributed on the frame 51. The lifting plate 53 has multiple through holes that cooperate with the four guide rods 52. The oil cylinder 55 is fixed on the base plate of the frame 51.

[0032] See Figures 1-4The driving force is converted into a horizontal force on the mold-shifting fork plate 3-10 via gear 32 and screw 35. The driving force exerted by the hydraulic cylinder 39 on the guide plate 36 on the support plate 38 is converted into a vertical force on the mold-shifting fork plate 3-10, giving it two degrees of freedom in both the vertical and horizontal directions. This facilitates the lifting and shifting function of the forming mold 46. The driving force is then converted back into a horizontal force on the mold-shifting fork plate 3-10 via gear 32 and screw 35. The driving force exerted by the hydraulic cylinder 39 on the guide plate 36 on the support plate 38 is converted into a vertical force on the mold-shifting fork plate 3-10, thus enabling the mold-shifting fork plate 3-10 to move horizontally. The mold-moving fork plate 3-10 has two degrees of freedom in the vertical and horizontal directions, which facilitates the function of moving and lifting the forming mold 46. In addition, the two linear guide rails 54 of the mold-moving lifting mechanism 5 are connected by screws and are symmetrically distributed on both sides of the frame 51, which facilitates the horizontal movement of the forming mold 46 placed on the linear guide rails 54. Four guide rods 52 are symmetrically distributed on the frame 51. The lifting plate 53 has four through holes to cooperate with the four guide rods 52 and ensure the stability of its vertical movement. The hydraulic cylinder 55 is fixed to the bottom plate of the frame 51 by screws and provides vertical driving force to the support plate 38.

[0033] In some embodiments, the adjustable injection system 1 is located behind the hydraulic clamping mechanism 2 and fixed above the support frame 14.

[0034] In fact, it is used to inject plasticized material into the mold cavity through the runner plate 26 for the injection process.

[0035] In some embodiments, the hydraulic mold clamping mechanism 2 is located at the center of the two side frames 51. The hydraulic mold clamping machine includes a hydraulic cylinder 21, a lower mold base 27, a lower heating plate 28, an upper mold base 23, an upper heating plate 24, and a Green column 29. The hydraulic cylinder 21 is located at the bottom of the lower mold base 27, the lower heating plate 28 is located on the top surface of the upper mold base 23, and the upper heating plate 24 is located on the bottom surface of the upper mold base 23.

[0036] See Figures 5-7 The hydraulic cylinder 21 in the hydraulic mold closing mechanism 2 provides the mold closing driving force to lift the lower mold base 27, the lower heating plate 28 on the lower mold base 27, and the forming mold 46 upward to the mold closing position to carry out the mold closing process.

[0037] In some embodiments, the four symmetrically distributed Green Pillars 29 are fixed on the base 22, the upper mold base 23 is fixed above the Green Pillars 29 by a threaded connection, and the four through holes on the lower mold base 27 are clearance fit with the Green Pillars 29.

[0038] In fact, the movement of the lower mold base 27 along the direction of the Green Pillars 29 can ensure that the lower mold base 27 is fixed by horizontal displacement through multiple Green Pillars 29 during the mold closing process, thereby improving the lifting stability of the lower mold base 27.

[0039] In some embodiments, the lower heating plate 28 has two symmetrically distributed mating grooves for mating with the mold moving fork plate 3-10 in the fork plate type mold moving and lifting mechanism 3.

[0040] In fact, the mold-moving fork plate 3-10 used in the fork plate type mold-moving lifting mechanism 3 allows the mold-moving fork plate 3-10 to pass through the lower heating plate to reach the bottom of the forming mold 46. Under the driving force of the hydraulic cylinder 39 in the fork plate type mold-moving lifting mechanism 3, the mold-moving fork plate 3-10 and the forming mold 46 are lifted upward to the horizontal straight direction where they are separated from the lower heating plate 28 and reach the opening and closing position.

[0041] In some embodiments, the opening and closing mechanism 4 is fixed to the upper end of the fork-plate type mold moving and lifting mechanism 3 by screw connection, and includes a clamping claw fixing platform 41, a mold opening cylinder 42, an opening and closing claw 43, and a claw mating block 44. The mold opening cylinder 42 and the opening and closing claw 43 are assembled on the clamping claw fixing platform 41, and the mold opening cylinder 42 is located on both sides of the opening and closing claw 43.

[0042] In fact, the opening cylinder 42 in the opening and closing mechanism 4 provides driving force to the opening and closing grippers 43 on both sides, which pulls the pair of lateral moving slides 45 on the forming mold 46, which has reached the opening and closing position, to open and close the forming mold 46, thereby exposing the formed product in the forming mold 46, which is convenient for subsequent mold removal, mold cleaning and material loading processes.

[0043] In some embodiments, the mold moving and lifting mechanism 5 is located on one side of the fork-plate type mold moving and lifting mechanism 3. The mold moving and lifting mechanism 5 includes a linear guide rail 54, a hydraulic cylinder 55, and a lifting plate 53. The hydraulic cylinder 55 is located at the bottom of the lifting plate 53, and the linear guide rail 54 is located at the bottom of the molding die.

[0044] In fact, the molding mold 46, which has completed the opening and closing process, is moved to the mold removal position by the linear guide rail 54 in the mold moving and lifting mechanism 5. The hydraulic cylinder 55 of the mold moving and lifting mechanism 5 provides a vertical driving force to the lifting plate 53, so that the molding mold 46 is vertically lifted and lowered to the optimal mold removal position set by the electronic control system 6, and the mold removal, mold cleaning and material loading processes are carried out.

[0045] In some embodiments, the electrical control system 6 includes a power control unit 61, a human-machine interface unit 62, and a rotating bracket 63. The human-machine interface unit 62 and the rotating bracket 63 are fixed on the upper mold base 23 of the hydraulic mold clamping mechanism 2. The power control unit 61 is located behind the support frame 14 of the adjustable injection system 1.

[0046] In practice, the system can monitor and control the operating status of each mechanism in real time, ensuring the intelligent operation of the entire production process. Operators can conveniently set parameters and monitor equipment through the human-machine interface 62, improving the transparency and controllability of the production process. The mold-moving and lifting mechanism 5 moves the mold 46, which has completed the opening and closing process, to the mold-removing position via the linear guide rail 54, and provides vertical driving force through the hydraulic cylinder 55 to lift the mold 46 to the optimal mold-removing position set by the electronic control system 6. This design not only improves the comfort and safety of operators but also significantly reduces labor intensity and further improves work efficiency.

[0047] In practical use, the working process of this invention includes the following steps:

[0048] S1. The forming mold 46 is located in the initial mold taking position. At this time, a pair of lateral moving slides 45 are in the pulled-out state. After the mold blank is placed into the exposed mold mounting cavity 47, the forming mold 46 is moved to the opening and closing position under the driving force provided by the linear guide rail 54 in the mold moving and lifting mechanism 5, and enters S2.

[0049] S2. After the forming mold 46 reaches the opening and closing position, the clamping block 44 and the opening and closing clamping 43 in the opening and closing mechanism 4 are in a cooperating state. The two opening cylinders 42 provide a pair of forces to tighten inward, tightening a pair of lateral moving slides 45 inward, so that the lateral moving slides 45 wrap around the placed mold blank and enter S3.

[0050] S3. After the forming mold 46 has completed the tightening process, the driving force provided by the hydraulic cylinder 3921 in the fork-plate type mold moving and lifting mechanism 3 lifts the mold moving fork plate 3-10 upward to contact the forming mold 46 above. Then, the driving force provided by the reduction motor 31 moves the mold moving fork plate 3-10 and the forming mold 46 horizontally to directly above the lower heating plate 28 in the hydraulic mold closing mechanism 2. After the forming mold 46 reaches the position, under the driving force provided by the hydraulic cylinder 39 in the fork-plate type mold moving and lifting mechanism 3, the mold moving fork plate 3-10 and the forming mold 46 move vertically downward to contact the forming mold 46 with the lower heating plate 28. After the forming mold 46 is placed on the lower heating plate 28, the mold moving fork plate 3-10 is located at the mating groove position of the lower heating plate 28. The driving force provided by the reduction motor 31 and the hydraulic cylinder 39 moves the mold moving fork plate 3-10 back to the initial position, and enters S4.

[0051] S4. After placing the molding die 46 on the lower heating plate 28, the hydraulic cylinder 21 in the hydraulic mold closing mechanism 2 provides driving force to the lower mold base 27, lifting the lower mold base 27, the lower heating plate 28, and the molding die 46 vertically upward to the mold closing position, and enters the mold locking injection process, then proceeds to S5.

[0052] S5. After the molding die 46 reaches the mold closing position, the adjustable injection system 1 injects the plastic material into the runner plate 26 in the hydraulic mold closing mechanism 2. The plastic material entering the runner plate 26 enters the mold cavity through four nozzles 26-1 for injection molding process, and enters S6.

[0053] S6. After the injection molding process is completed, the hydraulic cylinder 21 in the hydraulic mold closing mechanism 2 provides the mold opening force, so that the lower mold base 27, the lower heating plate 28 and the molding die 46 move downward to the initial position of the lower mold base 27 and enter S7.

[0054] S7. After the molding die 46, which has completed the injection process, reaches the initial position of the lower mold base 27, the hydraulic cylinder 39 and the reduction motor 31 in the fork-plate type mold moving and lifting mechanism 3 provide driving force to move the mold moving fork plate 3-10 to the mating groove position of the lower heating plate 28. The hydraulic cylinder 39 in the fork-plate type mold moving and lifting mechanism 3 provides vertical upward driving force to move the mold moving fork plate 3-10 upward to the horizontal straight direction where the lower heating plate 28 is out of contact with the molding die 46 and is in the open and closed position. The reduction motor 31 provides driving force to move the mold moving fork plate 3-10 together with the molding die 46 horizontally to the open and closed position, entering S8.

[0055] S8. After the forming mold 46 reaches the opening and closing position, the opening and closing gripper 43 and the gripper mating block 44 in the opening and closing mechanism 4 are in a mating state. The two opening cylinders 42 in the opening and closing mechanism 4 provide a pair of forces to the lateral moving slides 45 on both sides to open outward, exposing the already formed insulator product in the mold cavity and entering S9.

[0056] S9. After the opening process of the molding mold 46 is completed, the molding mold 46 is horizontally moved to the mold removal position above the mold removal mechanism 5 by the linear guide rail 54 in the mold moving and lifting mechanism 5. The driving state of the hydraulic cylinder 55 in the mold moving and lifting mechanism 5 is controlled by the electrical control system 6. The lifting platform and the molding mold 46 are vertically raised and lowered to the most suitable mold removal position. Then, the mold removal, mold cleaning and material unloading process is carried out, and the process proceeds to S10.

[0057] S10. After completing the mold removal, mold cleaning, and material release process, the lifting platform, together with the forming mold 46, returns to the initial mold removal position under the driving force provided by the hydraulic cylinder 55 in the mold moving and lifting mechanism 5, and returns to S1.

[0058] While embodiments of the present invention have been described in detail above, it will be apparent to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations fall within the scope and spirit of the invention as set forth in the claims. Furthermore, the invention described herein may have other embodiments and can be implemented or carried out in various ways.
