[0002] The automobile steering gear, also known as the steering machine or steering gear, is the most important component in the automobile steering system. Its function is to increase the force transmitted from the steering wheel to the steering transmission mechanism and change the direction of force transmission. Commonly used ones are rack and pinion type, worm crank pin type and recirculating ball type.

[0003] The Chinese patent with the publication number CN210848270U discloses a die-casting mold for automobile steering gear that is easy to demold, including a mold cavity, a mold cover plate, a square tube, a bar, a column rod, a guide groove, a slider, a first cylinder, a bottom plate, a second cylinder and a vibrator. The utility model has a reasonable design. By starting all the first cylinders and the second cylinder 1 in an extended state at the same time, the two mold cover plates and the two mold cavities are quickly disassembled to the surroundings, and the molded parts can be quickly exposed and processed to achieve the effect of rapid demolding, and at the same time, the mold can be quickly closed. By starting the vibrator and changing the vibration amplitude through the corresponding control element, it is convenient to separate the molded parts from the mold cavity, and the demolding operation can be carried out simultaneously to improve the demolding speed. The automobile steering gear die-casting mold in the application is realized by multiple cylinders, the overall cost is high, and it is also inconvenient to operate.

[0004] In view of this, the present utility model is proposed. Utility Model Content
