The utility model provides a double-color mould without art line sealing glue, which comprises a first injection module and a second injection module, the second injection module comprises a second injection front mould core and a second injection rear mould core which are arranged in a mutually opening and closing manner, and the second injection front mould core and the second injection rear mould core are encircled to form a second injection accommodating cavity; a first injection product formed by injection molding of the first injection module and an injection product composed of a second injection product closely attached to and surrounding the first injection product are arranged in the second injection containing cavity, and a second injection insert extending into the second injection containing cavity is arranged on the second injection front mold core; the bottom of the second-injection insert is provided with an inward concave cavity and a pressing edge arranged around the cavity, and the pressing edge is in smooth transition connection with the inner wall of the second-injection front mold core; by means of pre-pressing sealing of the insert, burrs and indentations are eliminated, appearance flaws caused by an art designing groove are avoided, the surface of a product is smoother, lines are smoother, plastic melt is effectively prevented from overflowing by accurately controlling the pre-pressing height and the glue sealing width, the reject ratio of the burrs, glue leakage and the like is remarkably reduced, and the reliability and the production efficiency of the mold are improved.

This utility model discloses a carton flipping device, relating to the field of carton storage and transportation technology. It includes a main body with a conveyor belt rotatably connected to its inner side. A pusher plate is fixedly connected to the outside of the conveyor belt. A flipped carton is placed on the upper side of the conveyor belt between two sets of pushers. The flipped carton has creases on its outer surface, and a box stud is riveted to its end. A baffle is fixedly connected to the upper end of the main body. An auxiliary flipping mechanism is installed on the upper side of the main body, and a stacking mechanism is fixedly installed at the end of the main body. This device automatically flips the carton using crease guidance and utilizes rotational thrust to transfer the box studs to the side joint, preventing damage from protrusions during stacking. Combined with conveyor positioning and flexible collection, it achieves efficient flipping, eliminates manual adjustment, ensures a flat, crease-free bottom surface of the carton in multi-layer stacks, and improves storage and transportation safety.

The invention discloses automatic welding equipment special for maintenance and replacement of electric heating elements of voltage stabilizers, and relates to the technical field of welding equipment for maintenance of the electric heating elements of the voltage stabilizers. The automatic welding equipment comprises a machine head shell, and a machine head clamping mechanism, a walking transmission mechanism, a welding machine head module and a wire feeding mechanism are arranged on the machine head shell; the machine head clamping mechanism is used for fixing the automatic welding equipment to a to-be-welded area, the walking transmission mechanism is used for driving the automatic welding equipment to rotate and move along a welding seam path, and at least four driving shafts are arranged in the automatic welding equipment to achieve the main rotation function, the arc length adjusting function, the welding seam swinging function and the wire feeding driving function correspondingly. The wire feeding mechanism is fixed to the machine head shell, and the whole rotation space of the automatic welding equipment is controlled within 160 mm. The full-automatic welding machine has the effect of achieving stable, high-precision and full-automatic welding of 2G position welding seams (butt joint / angle joint) between the electric heating element and the sleeve in a high-irradiation environment in an ultra-narrow rotation space smaller than or equal to 160 mm.
