Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machine assembly devices, and particularly relates to a die adjusting nut installation tooling. Background Art

[0002] The die adjusting nut is a part of the die adjusting device of a die casting machine or an injection molding machine. It is usually used in cooperation with a lead screw and adjusts the closing degree and position of the mold by rotation or movement. The die adjusting nut cooperates with the lead screw, and the distance between the molds is adjusted by rotating the nut to ensure the accurate closing of the mold and the accuracy of the product. During the injection molding process, the die adjusting nut can maintain the stability of the mold and prevent the mold from shifting or deforming due to uneven stress. The die adjusting nut usually has internal threads that match the threads of the lead screw. Its structure may include components such as a support plate, a nut gland, and a nut gasket, which together form a stable die adjusting mechanism. The working principle of the die adjusting nut is based on the thread fit between the lead screw and the nut. When the lead screw rotates, its threads interact with the threads of the nut, pushing the nut to move along the axial direction of the lead screw. By controlling the rotation direction and speed of the lead screw, the moving distance of the nut can be precisely adjusted, thereby realizing the adjustment of the mold. As the scale of die casting machines or injection molding machines becomes larger and larger, the die adjusting nuts are also getting larger and heavier. When installing the die adjusting nuts, it relies on manual labor to gradually screw them in with the help of a lever (steel pipe), which consumes a large amount of physical strength of the assembly workers and has very low efficiency.

[0003] To solve the above problems, a Chinese patent with the application number 201210452041.5 discloses an installation device for the die-adjusting screw nut of a large injection molding machine. The disclosed installation device for the die-adjusting screw nut includes a hydraulic station, a piston rod mounting plate, and a rotary mounting seat. A lifting cylinder connected to the hydraulic station is fixedly arranged vertically on the hydraulic station. The piston rod mounting plate is fixedly connected to the lifting piston rod of the lifting cylinder. A rotary cylinder connected to the hydraulic station is fixedly arranged horizontally on the piston rod mounting plate. A rotary piston is arranged in the rotary cylinder. The rotary piston is fixedly connected to a rotary piston rod. The rotary piston rod passes through the piston rod mounting plate and is fixedly connected to the rotary mounting seat. A rotation driving mechanism for driving the rotary piston rod to rotate is arranged on the rotary cylinder. A locking mechanism for coaxially fixing the die-adjusting screw nut in the rotary mounting seat is arranged on the rotary mounting seat. A Chinese patent with the application number 201911423416.3 discloses an automatic screwing device for the die-adjusting screw nut of a large injection molding machine. The disclosed automatic screwing device for the die-adjusting screw nut includes a positioning platform, an automatic screwing device for the die-adjusting screw nut, and a control device. The automatic screwing device for the die-adjusting screw nut includes a second base. A third sliding seat that slides longitudinally is arranged on the second base. A fourth sliding seat that slides horizontally is arranged on the third sliding seat. A fifth sliding seat that slides vertically is arranged on the fourth sliding seat. A sixth sliding seat that slides longitudinally is arranged on the fifth sliding seat. A first cylinder is arranged on the fifth sliding seat. A pair of rotatable rollers arranged in parallel are arranged on the sixth sliding seat. A seventh sliding seat that slides horizontally is arranged on the sixth sliding seat. A hydraulic motor is arranged on the seventh sliding seat. A gear is arranged on the output shaft of the hydraulic motor.

[0004] In the above-disclosed prior art, by coaxially fixing the die-adjusting screw nut in the rotary mounting seat, the lifting cylinder drives the rotary mounting seat to rise to the height where the tie rod is located, and the hydraulic station provides power to push the die-adjusting screw nut to the left by the rotary cylinder. At the same time, the servo motor rotates clockwise at a low speed and high torque to drive the rotary cylinder to screw the die-adjusting screw nut horizontally into the tie rod. Although this method can realize the automatic installation of the die-adjusting screw nut, the above device has a complex structure and a large floor area. When installing the die-adjusting screw nut, the die-adjusting screw nut needs to be transported to the above device and placed in the device. The installation is not only cumbersome and complex, but also the cost of the device is relatively high and the practicability is low. Summary of the Invention

[0026] Further, the installation mechanism 2 is fixed on the mobile trolley 1. When the die-adjusting lead screw nut 3 needs to be installed, the mobile trolley 1 drives the installation mechanism 2 to move to the position of the die-adjusting lead screw nut 3 and the pull rod 4. The installation mechanism 2 is located at the side of the mobile trolley 1, and the installation mechanism 2 further includes a support frame 201 for supporting the power motor 202 and the belt pulley 203.

Further, the power motor 202 can adopt a three-phase motor, and the power provided by the power motor 202 drives the driving sprocket 2021 and the chain to rotate.

[0028] In addition, a transmission shaft 2031 is connected to the belt pulley 203, a driven sprocket 2032 connected with the chain is arranged on the transmission shaft 2031, the transmission shaft 2031 is rotatably arranged on the support frame 201, the driven sprocket 2032 is arranged at the end of the transmission shaft 2031, and the driven sprocket 2032 and the driving sprocket 2021 are located on the same side of the support frame 201.

[0029] A limiting rod 208 for limiting the belt 207 is arranged above the belt pulley 203. The limiting rod 208 is connected to the support frame 201. Further, the limiting rod 208 is arranged above the belt pulley 203 and is located on the opposite sides of the belt pulley 203. The belt 207 is limited by the limiting rod 208 to prevent the belt 207 from disengaging from the driven belt pulley 203.

[0030] A wrap angle wheel 204 for restricting the sliding position of the belt 207 is arranged below the belt pulley 203. The wrap angle wheel 204 is arranged on the opposite sides of the belt pulley 203.
