Description

Technical Field

[0001] This utility model relates to the technical field of automobile molds, and in particular to a special crane for automobile molds. Background Technology

[0002] In the automotive manufacturing sector, mold lifting tools, as key tooling equipment, must meet requirements such as high-precision positioning, large load-bearing capacity, high-frequency cyclic use, and strict safety protection. However, due to the late start of related technologies in China, existing lifting tools still have shortcomings in terms of material performance, structural design, control precision, and safety protection mechanisms, resulting in a long-term reliance on imports for automotive mold lifting tools.

[0003] Currently, although imported lifting tools can meet basic usage needs, they are mostly designed for foreign mold standards and are difficult to fully adapt to the complex and diverse mold specifications in China, resulting in poor applicability. Utility Model Content

[0004] In view of the aforementioned problems with existing automotive mold lifting tools, the aim is to provide a dedicated lifting tool for automotive molds.

[0005] The specific technical solution is as follows:

[0006] A special lifting tool for automotive molds includes: a lifting frame and two lifting assemblies respectively installed on both sides of the lifting frame, each of the lifting assemblies comprising:

[0007] Two sliders are mounted on the hanger in a way that allows them to slide away from or close to each other.

[0008] Two grippers, each gripper being mounted on one of the two sliders;

[0009] A bidirectional lead screw, which is rotatably mounted on the hanger, and the two sliders are respectively threaded onto the outside of the bidirectional lead screw;

[0010] A driving component, which is connected to the bidirectional lead screw, is used to drive the bidirectional lead screw to rotate so that the two sliders slide away from or towards each other.

[0011] As a further improvement and optimization of this solution, the driving component is a motor, which is mounted on the hanger and connected to the bidirectional lead screw drive.

[0012] As a further improvement and optimization of this solution, the motor is installed on the top of the hanger, and the output end of the motor is connected to the middle of the bidirectional lead screw through a transmission component.

[0013] As a further improvement and optimization of this solution, the transmission component is a gear set structure.

[0014] As a further improvement and optimization of this solution, a hook is also provided at the bottom center of the hanger.

[0015] As a further improvement and optimization of this solution, four suspension rope pulleys are also installed on the top of the hanger. The four suspension rope pulleys are located at the four corners of the hanger and are distributed in a rectangular structure.

[0016] As a further improvement and optimization of this solution, the top of the hanger also has two positioning cylinders, which are distributed along the diagonal of the hanger.

[0017] As a further improvement and optimization of this solution, the motor is a geared motor.

[0018] As a further improvement and optimization of this solution, a PN encoder is installed at the tail of the geared motor.

[0019] The positive effects of the above technical solution compared with the existing technology are:

[0020] In this invention, when hoisting an automobile mold, the main unit (such as a gantry crane) moves the lifting device to the automobile mold. The drive unit of each hoisting assembly drives the two sliders to move closer to each other, and the two hooks respectively engage with the two hook slots on the automobile mold, thereby hoisting the automobile mold. By having the four hooks in the two sets of hoisting assemblies respectively engage with the four hook slots on the automobile mold, the hoisting safety of the automobile mold is improved. At the same time, the distance between the two hooks in the same set of hoisting assemblies can be adjusted to adapt to the hoisting work of different mold specifications, making it highly applicable.
