Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a high-wear-resistant and long-life wind power generation gearbox casting mold. Background Art

[0002] Gearboxes have a wide range of applications, such as in wind turbines. Gearboxes are an important mechanical component that is widely used in wind turbines. Their main function is to transmit the power generated by the wind rotor under the action of wind to the generator and make it obtain the corresponding speed. Usually, the speed of the wind rotor is very low, far from the speed required by the generator to generate electricity. It must be achieved through the speed-increasing effect of the gear pair of the gearbox, so the gearbox is also called a speed-increasing box. The outer shell of the gearbox is cast by a casting mold.

[0003] Prior art publication number CN214212131 U discloses a gearbox casting mold comprising a left mold, a right mold, and an upper mold. The left and right molds are connected to form a complete mold cavity. A connecting groove is provided on one side of the left mold, and a connecting block is provided at one end of the right mold. The right mold is connected to the connecting groove on the left mold via the connecting block. Both the left and right molds are equipped with cooling mechanisms. In this gearbox casting mold, the left, right, and upper molds are combined to form a complete mold. Furthermore, an ejection mechanism can be used to eject castings adhered to the template. If castings adhere to the left and right molds, the left and right molds can be separated to facilitate removal of the castings. The cooling mechanism is used to rapidly cool the components within the mold, accelerating the molding of the castings.

[0004] The gearbox casting mold mentioned above has a lower mold composed of two half molds. When the casting adheres to the lower mold, the two half molds often need to be separated.
