This invention discloses an in-mold gate cutting device for logo injection molds, relating to the field of injection molding, and solves the problem of deformation and whitening at the shearing opening of symmetrical logo injection molds. The in-mold gate cutting device for logo injection molds includes a support frame, with a force-applying component mounted at the top of the support frame. This force-applying component cuts the logo injection mold. A positioning component is mounted on one side of the force-applying component, and the positioning component is aligned with a positioning template. The force-applying component includes a drive motor, a first clamping plate, and a second clamping plate. The drive motor drives the first and second clamping plates to move relative to each other in the horizontal direction through a transmission structure. The positioning component includes a first positioning template, a second positioning template, and a logo body. The first and second positioning templates are aligned to cut the logo body. In this invention, the force-applying component and the positioning component work together to apply force from both sides of the logo body, preventing the product from deflecting or shifting at the moment of cutting. After cutting, the product automatically falls from the opening.

A notch-cutting device includes a mounting frame, a cutter, and a drive unit. The mounting frame includes a support base and a material holder disposed on the support base. The cutter includes a first end, a middle section, and a second end, with the middle section located between the first and second ends and rotatably connected to the support base. The drive unit is connected to the first end and drives the cutter to rotate, causing the second end to cut the workpiece on the material holder, thereby forming a notch on the workpiece. In this application, the notch-cutting device mainly consists of a mounting frame, a cutter, and a drive unit, with a simple overall structure. Compared to complex traditional machining equipment, it has fewer parts and a relatively simple manufacturing process, thus reducing the manufacturing cost of the equipment. Because the drive unit can quickly drive the cutter to rotate and complete the cutting action, the entire processing can be completed in a short time, greatly shortening the processing time of a single workpiece, meeting the needs of large-scale production, and improving the production capacity of enterprises.

This invention provides a thread-cutting structure for a sewing machine, belonging to the field of sewing machine technology. It solves the problems of insufficient reliability and short service life of existing thread-cutting structures. The thread-cutting structure of this sewing machine includes a pressure plate, an auxiliary knife mounted on the machine base, and a movable knife located below the needle plate and capable of swinging up and down around the shuttle shaft of the sewing machine. The auxiliary knife has a thread-cutting end with an auxiliary cutting edge. The movable knife has a thread-hooking groove, and the upper edge of the hook groove forms the moving cutting edge. When the movable knife swings upward, the hook groove is aligned vertically with the needle drop hole. When the movable knife swings downward, its moving cutting edge engages with the auxiliary cutting edge. The pressure plate is movably connected to the upper side of the movable knife. The movable knife also has a return spring acting on the pressure plate. When the auxiliary cutting edge engages with the movable cutting edge, the thread-cutting end of the auxiliary knife abuts against the lower side of the pressure plate. This invention improves the reliability and service life of the thread-cutting structure.
