This invention relates to the field of gear processing and casting technology, specifically to a casting and forming device for processing planar helical cylindrical gears. The device includes a worktable and a vertical block on the worktable. A first rotating gear disk is rotatably mounted on one side of the worktable, and a lower mold is mounted on the first rotating gear disk. A mounting base is located on one side of the vertical block, and a rotating column is rotatably mounted inside the mounting base. An electric telescopic rod is located inside the rotating column, and an upper mold adapted to the lower mold is located at the telescopic end of the electric telescopic rod. A rotating assembly is also included, comprising a lower rotating module and an upper rotating module. Compared to existing technologies, this application uses the upper rotating module to drive the upper mold and the lower rotating module to drive the lower mold to synchronously output micro-rotation in opposite directions, causing the relative motion of the two molds to exhibit a helical composite trajectory. This allows for unlocking before gradual disengagement when there is a mechanical engagement tendency between the helical positioning teeth and the tooth cavity.

The application provides a rubber composition for preparing adhesive glue, the adhesive glue and a preparation method and application thereof. The rubber composition comprises, in parts by weight: 100 parts of base rubber, 100-500 parts of softening agent, 3-15 parts of tackifier, 5-40 parts of lignin modified glass microbeads, 4-44 parts of auxiliary agent, 2.5-7 parts of vulcanizing agent and 1-1.5 parts of vulcanization accelerator. The lignin modified glass microbeads comprise hollow glass microbeads and lignin coupled on the surface of the hollow glass microbeads. The application introduces the vulcanizing agent to vulcanize the rubber composition under mild conditions to obtain the adhesive glue, thereby simplifying the curing process of the adhesive glue. Meanwhile, through the synergistic effect among the components in the rubber composition, the flexibility and elasticity of the prepared adhesive glue and the matching property of the adhesive glue with the dynamic deformation of the tire are effectively improved, thereby reducing the delamination or tearing phenomenon between the soundproof cotton and the inner wall of the tire, and the adhesive effect of the adhesive glue is significantly improved.

This utility model discloses a storage box with handle holes, including a storage box body, a tray, and multiple side panels. Handle holes are provided on both sides of the storage box body. The tray is disposed on the bottom surface of the storage box body, and the side panels are disposed on both sides of the storage box body. One end of each side panel is fixedly connected to the tray, and the other end of each side panel is enlarged to form a limiting part. A handle frame protrudes from the middle of each limiting part, and the handle frame is inserted into the handle hole. A cover plate is provided on the outer surface of each limiting part to cover the handle hole. Positioning mechanisms are installed at both ends inside the handle frame. This utility model has a simple structure. The handle frame is inserted into the handle hole, and the handle frame is connected to the tray through the side panels. The side panels and tray can transfer the weight of the handle hole to the bottom of the storage box body, greatly reducing the possibility of the handle hole being torn. The cover plate can cover and seal the handle hole, ensuring the airtightness of the storage box body during storage.
