Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a guide device for a gear box injection mold. Background Art

[0002] Gearboxes are a crucial mechanical component widely used in wind turbines. Their primary function is to transmit the wind power generated by the rotor to the generator, ensuring a corresponding rotational speed. Injection molds are tools used to produce plastic products; they also give them a complete structure and precise dimensions. Injection molding is a process used in the mass production of complex components. Specifically, molten plastic is injected into the mold cavity under high pressure using an injection molding machine. After cooling and solidification, the resulting molded product is formed. Guides are required to guide the opening and closing of the injection mold. This prevents mold misalignment and ensures more consistent product quality.

[0003] The Chinese patent publication number is CN220995292U, and the authorization announcement date is May 24, 2024. A guiding device for an injection mold solves the problems of inconvenient maintenance and unsafe transportation in the prior art, including an upper mold, an upper mold frame, a lower mold frame, and a handle. The upper mold is internally rotatably installed with a driving shaft, the top of the driving shaft is fixedly connected to a knob, and a first synchronous wheel is fixedly sleeved on the outer peripheral surface of the driving shaft. The upper mold is internally fixedly connected to two symmetrically arranged fixed blocks, one of which is internally rotatably installed with a driven threaded rod. Through the arrangement of the knob, the driving shaft and other structures, when the four positioning rods of the upper mold frame pass through the four positioning holes of the upper mold, the knob is rotated to drive the driving shaft to rotate, drive the driven threaded rod and the follower threaded rod to rotate, and drive the clamping rod to pass through the positioning rod, making it more convenient to disassemble and repair the upper mold after damage.
