Description

Technical Field

[0001] This utility model relates to the field of mold clamping machine technology, and in particular to a parallelism adaptive adjustment structure for a mold clamping machine. Background Technology

[0002] As a core piece of equipment in the mold fitting process, the mold clamping machine plays a crucial role in the later stages of mold manufacturing. Its working logic is as follows: focusing on the fitting stage of the upper and lower molds, red lead is first evenly applied to one side of the mold. The equipment is used to make the moving mold and the fixed mold fit together precisely. Then, according to the process requirements, the mold is pressurized and clamped at different pressure levels. After the mold clamping and pressurization are completed, the mold is opened. Technicians observe the state of the red lead transfer to the other side of the mold to judge the fit of the mold fitting surfaces and then decide whether to carry out mold repair work. This process needs to be repeated until the mold fitting accuracy meets the production requirements.

[0003] However, existing mold clamping machines have technical shortcomings. Their clamping force is mainly provided by four outer tie rods. Under continuous high-intensity pressure, the mechanical properties of the mold plate structure change after long-term use. Specifically, a slight deformation occurs at the center of the mold plate. When this deformation accumulates to a certain extent, the red lead imprint cannot be properly and completely imprinted onto the corresponding area of ​​the mold base plate during the mold clamping inspection process. This prevents technicians from accurately obtaining the true state of the mold's mating surface, ultimately leading to errors in mold verification results. Consequently, products subsequently produced based on this mold may have quality risks such as dimensional deviations and surface defects. To address these issues, we propose a parallelism adaptive adjustment structure for the mold clamping machine. Utility Model Content

[0004] The purpose of this invention is to provide a parallelism adaptive adjustment structure for a mold clamping machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a parallelism adaptive adjustment structure for a mold clamping machine, comprising a base support frame, a frame column mounted on the base support frame, a mold transfer slide mounted at the front end of the frame column, two mold drive cylinders mounted at the top end of the frame column, a fixed template mounted at the bottom end of the frame column, a movable template mounted on the fixed template, a support block mounted in the middle of the movable template, horizontal sensors mounted on both sides of the top of the support block, and uprights mounted on both the front and rear sides of the support block. Servo motors are mounted at the top of both sets of uprights, and lead screws are rotatably connected inside both sets of uprights. The output ends of both sets of servo motors are connected to the ends of the lead screws. A guide groove is provided in the middle of the upright. Threaded auxiliary seats are threadedly connected to the outside of the lead screws. Guide blocks are mounted on the outer walls of the threaded auxiliary seats. Mounting seats are mounted at opposite ends of the two sets of threaded auxiliary seats. The support block is connected to the mounting seat via a quick-release assembly.

[0006] As an improved technical solution, the quick-release assembly includes two sets of positioning screws fixed to the top of the support block. The tops of both sets of positioning screws penetrate into the interior of the mounting base, and the outer walls of both sets of positioning screws are threaded with hexagonal nuts.

[0007] As an improved technical solution, a maintenance ladder is installed on the side end of the frame column.

[0008] As an improved technical solution, a control panel is installed on the front side of the top of the frame column, and the servo motor and the level sensor are electrically connected to the control panel through wires.

[0009] As an improved technical solution, the outer wall of the guide block is fully fitted with the inner wall of the guide groove, and the guide block and the guide groove are slidably connected.

[0010] As an improved technical solution, the horizontal sensor is a dual-axis tilt sensor.

[0011] As an improved technical solution, the lead screw is a ball screw with a lead of 5mm and a diameter of 16mm.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are: I. This utility model features a liftable support block installed in the middle of the fixed mold template, with two sets of level sensors mounted on the support block. The level sensors monitor the horizontal state of the support block in real time. If tilting is detected, a servo motor drives the lead screw to rotate, causing the threaded auxiliary seat to move along the guide groove, thereby raising or lowering the mounting seat. This achieves automatic leveling of the support block and automatic adjustment of the parallelism of the middle of the fixed mold template during mold closing. This avoids the mold template deformation problem caused by long-term use of traditional mold closing machines, ensures uniform distribution of red lead marks during mold closing, improves the accuracy and efficiency of mold fitting, and ultimately guarantees the quality of the molded products.

[0013] II. This utility model has two sets of positioning screws installed on the support block, which can lock or loosen the hexagonal nut to achieve quick connection or separation between the support block and the mounting base. This facilitates the maintenance and replacement of the support block or the horizontal sensor and improves the maintainability of the equipment. Attached Figure Description

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a parallelism adaptive adjustment structure for a mold clamping machine includes a base support frame 1, a frame column 2 mounted on the base support frame 1, a mold transfer slide 3 mounted at the front end of the frame column 2, two combination mold drive cylinders 4 mounted at the top end of the frame column 2, a fixed template 5 mounted at the bottom end of the frame column 2, a movable template 7 mounted on the fixed template 5, a support block 9 mounted in the middle of the movable template 7, and horizontal sensors 10 mounted on both sides of the top end of the support block 9. The support block 9 is also equipped with horizontal sensors 10 on its front and rear sides. Each set of two sets of supports is equipped with a stand 11. A servo motor 12 is installed at the top of each set of supports 11. A lead screw 13 is rotatably connected inside each set of supports 11. The output ends of each set of servo motors 12 are connected to the ends of the lead screw 13. A guide groove 14 is provided in the middle of the stand 11. A threaded sub-seat 15 is threadedly connected to the outside of each lead screw 13. A guide block 16 is installed on the outer wall of each threaded sub-seat 15. A mounting seat 17 is installed at one end of each set of threaded sub-seats 15. The support block 9 is connected to the mounting seat 17 through a quick-release assembly.

[0018] By installing a liftable support block 9 in the middle of the fixed template 5, and installing two sets of level sensors 10 on the support block 9, the level sensors 10 monitor the level status of the support block 9 in real time. If tilting is detected, the servo motor 12 drives the lead screw 13 to rotate, which drives the threaded sub-seat 15 to move along the guide groove 14, thereby raising or lowering the mounting seat 17, realizing the automatic leveling of the support block 9, realizing the automatic adjustment of the parallelism of the middle of the fixed template 5 during the mold closing process, avoiding the template deformation problem caused by long-term use of traditional mold closing machines, ensuring the uniform distribution of red lead marks during the mold closing process, improving the accuracy and efficiency of mold fitting, and ultimately ensuring the quality of molded products.

[0019] In other embodiments, the quick-release assembly includes two sets of positioning screws 18 fixed to the top of the support block 9. The tops of the two sets of positioning screws 18 penetrate into the interior of the mounting base 17, and the outer walls of the two sets of positioning screws 18 are threaded with hexagonal nuts 19. By installing two sets of positioning screws 18 on the support block 9, the hexagonal nut 19 can be locked or loosened to achieve quick connection or separation between the support block 9 and the mounting base 17, which facilitates the maintenance and replacement of the support block 9 or the horizontal sensor 10 and improves the maintainability of the equipment.

[0020] In other embodiments, a maintenance ladder 6 is installed on the side end of the frame column 2; This design allows maintenance ladder 6 to provide access for technicians to move up and down the racks, improving equipment safety and ease of operation.

[0021] In other embodiments, a control panel 8 is installed on the front side of the top of the frame column 2, and the servo motor 12 and the level sensor 10 are electrically connected to the control panel 8 through wires. This design enables the control panel 8 to precisely control the servo motor 12 and the level sensor 10, improving the human-machine interaction experience and facilitating real-time control and debugging by operators.

[0022] In other embodiments, the outer wall of the guide block 16 is fully fitted with the inner wall of the guide groove 14, and the guide block 16 and the guide groove 14 are slidably connected. This design allows the guide block 16 to slide within the guide groove 14, restricting the threaded sub-seat 15 to move only axially, preventing rotation, ensuring the stability and accuracy of the adjustment process, and avoiding structural jamming.

[0023] In other embodiments, the horizontal sensor 10 is a dual-axis tilt sensor; Dual-axis tilt sensors are suitable for industrial environments. They are highly resistant to vibration and shock and can output tilt angle data in real time, which is convenient for the main controller to process and provide feedback control.

[0024] In other embodiments, the lead screw 13 is a ball screw with a lead of 5 mm and a diameter of 16 mm; Because ball screws have high transmission efficiency, good axial stiffness, and high positioning accuracy, they are suitable for servo motor drives and can achieve precise position control.

[0025] This utility model provides a parallelism adaptive adjustment structure for a mold clamping machine, and its specific working principle is as follows: During the detection phase: The level sensor 10 monitors the level status of the support block 9 in real time and transmits the data to the control system.

[0026] Judgment and decision: The control system determines whether there is a tilt based on sensor data. If the tilt exceeds the allowable range, the servo motor 12 is started.

[0027] Adjustment execution: Servo motor 12 drives lead screw 13 to rotate, which drives threaded sub-seat 15 to move along guide groove 14, pushes or pulls mounting seat 17, thereby adjusting the position of support block 9 and restoring the parallelism between moving template 7 and fixed template 5.

[0028] Feedback and stabilization: During the adjustment process, the horizontal sensor 10 continuously provides feedback data until the preset parallelism requirement is met. At this point, the system stops adjusting and enters the mold closing operation.

[0029] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.

[0030] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
