The invention belongs to the technical field of cutting equipment, and specifically discloses a pipe cutting and grinding device. The pipe cutting and grinding device comprises a cutting mechanism anda grinding mechanism which are connected to the same rotating shaft, wherein a transmission gear and two fixed pulleys are arranged on the rotating shaft; a rack which is fixed to a machine frame isengaged with the transmission gear; the grinding mechanism comprises a rotating barrel which is fixed to the rotating shaft, and a grinding plate is arranged on the rotating barrel; a square shaft isin sliding connection with the interior of the rotating barrel, and a threaded rod which is in thread connection with the rotating barrel is rotatably connected to the square shaft; and the threaded rod is in sliding connection with a sliding plate, and the sliding plate is in sliding connection with the machine frame. The pipe cutting and grinding device further comprises a conveying roller, a first clamping mechanism and a second clamping mechanism; the first clamping mechanism comprises a clamping block and a fixing block; a sliding rope is connected between the clamping block and the corresponding fixed pulley; the second clamping mechanism is in sliding connection with a working platform; a baffle plate is arranged at the left end of the working platform; and magnetic parts which areattracted to and repelled by each other are arranged between the baffle plate and the second clamping mechanism. According to the scheme, the pipe cutting and grinding device has the advantages that anotch of a steel pipe can be ground while the steel pipe is cut, so that the working efficiency is improved.

The invention relates to a stay bar for outdoor cabinet door upturning and an outdoor cabinet. The stay bar for outdoor cabinet door upturning comprises a first connecting rod, a second connecting roda limiting piece, sliding chutes are formed in the first connecting rod in the length direction, barb chutes are connected and communicate with the lower sides of the sliding chutes, and the barb chutes and the sliding chutes are arranged with an included angle; the second connecting rod is inserted into the first connecting rod and slides in the length direction of the first connecting rod; barbholes parallel to the sliding chutes are formed in the second connecting rod; the limiting piece penetrates through the sliding chutes and the barb holes, when the first connecting rod slides relative to the second connecting rod, the limiting piece moves in the sliding chutes with the barb holes; and when the limiting piece moves to the joint of the sliding chutes and the barb chutes, the limiting piece falls into the barb chutes, limiting clamping of the barb chutes and the barb holes is realized, and limiting clamping of the first connecting rod and the second connecting rod is realized. The stay bar for outdoor cabinet door upturning is simple in structure, is convenient and reliable to fix, is low in cost and is convenient to replace and maintain.

The invention belongs to the technical field of cutting equipment, and particularly discloses a pipe cutting device. The pipe cutting device comprises a sliding rail and a motor in sliding connectionwith the sliding rail. A transmission gear and a rotating shaft are connected to an output shaft of the motor, a machine frame is provided with a rack engaged with the transmission gear, a cutting sawblade is fixedly connected to the rotating shaft, and a sliding plate is rotationally connected to the end of the rotating shaft. A fixed plate is arranged on the right of the sliding plate, a lifting plate is arranged between the sliding plate and the fixed plate, a clamping plate is arranged below the lifting plate, the two ends of the clamping plate are in sliding connection with the sliding plate and the fixed plate correspondingly, a water bag is arranged between the lifting plate and the clamping plate, and the water bag is connected with a water pipe. A push plate with a through hole is in sliding connection with the interior of the fixed plate, the push plate is fixedly connected with the clamping plate, a base is arranged below the clamping plate, and one side of the base is provided with a trough and a baffle. A steel pipe is rapidly cut, and working efficiency is improved.

The invention discloses a plastic injection mold, and relates to the technical field of injection molding. A rear formwork bottom plate is included. A rear formwork on the rear formwork bottom plate is detachably connected with a front formwork on a front formwork bottom plate. A cavity for mold injection molding is formed by a rear mold core formed by the upper portion of the rear formwork and afront mold core formed at the lower portion of the front formwork. Each exhaust assembly comprises a pipe cavity, wherein one end of the pipe cavity communicates with the cavity, the other end of thepipe cavity upwards extends out of the top face of the front formwork bottom plate, meanwhile, the pipe cavity is internally provided with a matched exhaust pipeline, and one end of the exhaust pipeline communicates with the cavity and is provided with a ventilation micro hole ring. According to the plastic injection mold, surplus air in the cavity is exhausted in time, accordingly, the phenomenonof air hole generation in the injection molding process is avoided, and the mold injection molding effect is improved; and an activated carbon adsorption plate can be utilized for adsorbing harmful molecules contained in hot melting plastic raw materials, and accordingly the body health of workers is facilitated while exhausting is guaranteed.
