Rotation type demolding mechanism for J-shaped drain trap

Abstract

The invention relates to a rotation type demolding mechanism for a J-shaped drain trap. The mechanism comprises a lower compound plate, wherein mold feet are mounted on the lower compound plate, a thimble base plate and a thimble panel are arranged among the mold feet, and an ejector rod is mounted between the thimble base plate and the thimble panel; a movable mold frame is mounted on the mold feet, a movable model cavity is formed in the movable mold frame, a fixed model cavity is formed in the movable model cavity, mold cores are arranged in the model cavities, and J-shaped drain traps are arranged among the model cavities and the mold cores in an injection molding manner. The mechanism is characterized in that left and right lengthened type chutes are respectively arranged on the left and right sides of the movable mold frame, and left and right depression bars are respectively arranged on the left and right chutes; left and right sliding block seats are arranged among the left and right depression bars, and the left and right chutes, and straightly-drawn mold cores are mounted on the left and right sliding block seats; connecting plates are mounted below the left and right sliding block seats; guide troughs are formed in the left and right lengthened type chutes and are matched with the connecting plates; a reverse-pushing oil cylinder is mounted below the left and right lengthened type chutes; fixed plates are mounted on the front and rear sides of the movable mold frame, and front and rear oil cylinders are mounted on the fixed plates and are connected with racks; rotating gears are mounted in the movable mold frame and are meshed with the racks; rotating plates are arranged on the rotating gears, rotating mold core sliding blocks are mounted on the rotating plates, and rotating mold cores are mounted on the rotating mold core sliding blocks and are matched with bent pipe parts of the J-shaped drain traps.

Description

technical field [0001] The invention relates to a demoulding mechanism for a water trap, in particular to a rotary type demoulding mechanism for a J-shaped water trap. Background technique [0002] J-shaped elbow pipe fitting is a commonly used water trap pipe fitting. A certain amount of water can be kept in the water trap pipe fitting to isolate the air under the sewer from the indoor air, preventing odor and small insects from entering the room, which is harmful to people's life. Levels and physical fitness have helped a lot. However, there is a big problem with the structure of the mold. Since the diameter of the J-shaped trap is small, and the distance between the two diameters is very close to each other, when the direct-drawing mechanism and the rotary core-pulling mechanism are installed in the mold, the direct-drawing mechanism will The rotary core-pulling mechanism is blocked, so that the rotary core-pulling mechanism has no place to pull the core. Most of the ex...

However, there is a big problem with the structure of the mold. Since the diameter of the J-shaped trap is small, and the distance between the two diameters is very close to each other, when the direct-drawing mechanism and the rotary core-pulling mechanism are installed in the mold, the direct-drawing mechanism will The rotary core-pulling mechanism is blocked, so that the rotary core-pulling mechanism has no place to pull the core

Most of the existing skills can only use semi-automatic production. The so-called semi-automatic production means that after the product is injected, the core and the product are taken out together, and then the demoulding is performed manually. The production efficiency is low, the labor intensity of the workers is high, and the labor cost is high.
