This invention provides a molding die for an automotive roof, comprising a fixed mold, a moving mold, a middle mold, and an injection molding system. The fixed mold has a first molding groove and an injection rib groove, with shearing surfaces at its edges. The moving mold has a second molding groove and punching surfaces at its edges. The middle mold is located between the fixed and moving molds, and is provided with shearing blades matching the shearing surfaces and sharp blades matching the punching surfaces at intervals. The injection molding system connects to the injection rib grooves. During mold closing, the first and second molding grooves form a composite cavity to complete the composite molding of the substrate and the fabric, as well as the injection molding of the ribs. Simultaneously, the moving mold pushes the middle mold to move, the sharp blades and punching surfaces cooperate to punch the edges of the fabric, and the shearing blades and shearing surfaces cooperate to cut the edges of the substrate. This invention integrates molding, injection, composite molding, and cutting processes into a single mold, significantly reducing mold switching, improving production efficiency and cutting accuracy, and lowering production costs.

This utility model discloses a manual die-cutting machine device, including a lower base, an electrode platform mounted on the lower base, a guide post mounted on the lower base, an upper base plate slidably connected to the guide post, and a clamping assembly mounted on the upper base plate. The clamping assembly includes a plurality of opposing clamping sliders slidably connected to the upper base plate. The upper base plate has a hollow portion aligned with the electrode platform, and a clamping opening for clamping a die is provided on the opposite side of each clamping slider. This utility model provides a manual die-cutting machine device that can quickly install various sizes and specifications of dies, improving the adaptability and flexibility of the device, enabling multi-specification cutting operations, and increasing production efficiency.

This utility model discloses an auxiliary structure for a cutting and packaging machine. The key technical features include a cutting and packaging machine body with two sets of side supports mounted on it. A cutting blade module is installed between the two sets of side supports. A linear lead screw module is mounted on the cutting and packaging machine body, and an auxiliary detection structure is mounted on the linear lead screw module. When the packaging material to be cut is moved onto the cutting and packaging machine body for cutting, an industrial vision camera can perform three-axis moving visual inspection along the top of the side supports. Compared to traditional manual visual inspection, the auxiliary detection structure of this application ensures precise movement of the industrial vision camera in three directions, thereby achieving accurate visual inspection. This helps improve the accuracy and consistency of cutting packaging materials, reduces dimensional errors, and enables automated visual inspection, reducing manual operation.

The application relates to the technical field of wire cutting equipment, and discloses a wire cutting machine for die manufacturing, which comprises a base, a machining box fixedly connected to the top front side of the base, a rack fixedly connected to the top rear side of the base, an adjusting mechanism arranged on the front side of the rack, a shell, a motor one fixedly connected to the right side of the shell, an output end of the motor one penetrating through the shell and fixedly connected with a cam, a bottom plate fixedly connected to the bottom of the inner side of the shell, and a damping hydraulic cylinder fixedly connected to the top of the bottom plate. The motor drives the cam to rotate, the cam cooperates with the frame to flexibly adjust the tension of the wire electrode, and the damping hydraulic cylinder and the spring one can effectively absorb the high-frequency micro-vibration of the wire electrode caused by the impact force in the discharge machining moment, so that the tension fluctuation is controlled within a very small range.

This disclosure provides a battery cell, comprising: a battery cell housing including a side wall and a top plate, wherein a receiving space is formed inside the side wall and a through hole is formed in the top plate; an electrode assembly disposed in the receiving space of the battery cell housing; a first current collector electrically connected to a first electrode tab of the electrode assembly; an electrode terminal electrically connected to the first current collector through the through hole; and a gasket disposed between the electrode terminal and the top plate and having electrical insulation properties, wherein the top plate includes a protrusion and a recess, the protrusion protruding in one direction along the edge of the through hole and the recess recessing in the one direction.

This invention discloses a cable cutting device, including a support, a cable feeding mechanism, a cable delivery mechanism, a fastening mechanism, and a cutting mechanism. The cable feeding mechanism is rotatably connected to the support. The cable delivery mechanism includes a sliding mechanism, a reciprocating pushing mechanism, and a clamping mechanism. The clamping mechanism includes a cable delivery roller and a pressure block. One or more cable delivery rollers are fixed to the support and rotatably connected to it. The pressure block cooperates with the cable delivery roller to clamp the cable. The reciprocating pushing mechanism moves the pressure block closer to or away from the cable delivery roller. The sliding mechanism drives the reciprocating pushing mechanism and the pressure block to slide along a direction perpendicular to the roller axis of the cable delivery roller. The reciprocating pushing mechanism also drives the fastening mechanism to engage with the support surface to fasten the cable when the pressure block and cable delivery roller release the cable, and to release the cable when the pressure block and cable delivery roller clamp the cable. The cutting mechanism is fixed to the support and is used to cut the cable. This improves the cutting accuracy, allows for adjustable and controllable cutting length, and reduces dimensional errors caused by the bending of long cables during the cutting process.
