The utility model provides a plastic suction mold for a box liner, and belongs to the technical field of molds. Comprising a mold body, a fixed seat is fixed to the edge of the bottom of the mold body in a surrounding mode, a containing groove is formed in the edge of the outer side of the fixed seat in a surrounding mode, a movable frame is rotationally installed in the containing groove and moves in a semi-arc shape along the upper portion of the mold body, and a plurality of nozzles are arranged on the inner side of the movable frame; a connecting pipe externally connected with a release agent is fixed at one end of the outer side of the movable frame; the interior of the die body is hollow, a cooling block covers the inner top surface of the die body, a cooling channel is distributed in the cooling block, and a cooling water connector communicated with the cooling channel is fixed on the surface of the cooling block. According to the box liner demolding device, a demolding agent can be conveniently, rapidly and evenly sprayed, demolding of the box liner is facilitated, the formed box liner can be rapidly cooled and solidified, the machining efficiency is improved, and the overall using effect is good.

This invention provides an output head protective sleeve and a laser anti-evaporation coating system manufactured by metal additive manufacturing. The system includes an output head protective sleeve body for protecting the laser output head. A honeycomb structure is provided on the inner wall of one end of the output head protective sleeve body, and an electromagnetic structure for generating a magnetic field is provided on the side wall of the other end of the output head protective sleeve body. This invention enables metal vapor to be adsorbed within the honeycomb structure, preventing continuous refraction of the metal vapor and thus preventing the accumulation of metal vapor around the lens, thereby avoiding the formation of a coating on the lens.

The application relates to the technical field of water supply pipe networks, and discloses a pipe network rapid butt joint sealing device, which comprises a base, a sealing assembly installed on the top of the base, and two sliding seats one. The sealing assembly comprises two hot pressing rings one and two installed on a hot pressing plate. The two hot pressing rings one and two respectively heat the two butt joint pipe network end portions, so that the two pipe network end portions respectively form outer conical and inner conical regions, the two pipe networks can be nested through the conical structure when butt joint, the molten pipe material deeply penetrates and fuses under extrusion, a stronger anti-pulling structure is formed, the problems of friction damage, leakage risk and inconvenience of later construction and maintenance caused by the turn-up edge are solved, the whole process control of pipe network positioning, heating, lamination and nested extrusion is realized, the sealing property and the structural stability of the conical butt joint are ensured, and the pipe cylinder can better adapt to pressure fluctuation and foundation settlement in operation.
