The utility model discloses a torsion spring and buffer's combination reset device is provided with torsion spring reset mechanism and buffer in the door leaf side part, the torsion spring reset mechanism is equipped with the lower limit position cover, the pivot and upper limit position cover that connect in proper order, and the pivot outside is equipped with the sheath and torsion spring, and is equipped with the locating sleeve and locating block at the upper limit position cover, the one end of torsion spring is connected with lower limit position cover, and the other end is connected with metric shaft sleeve and intermediate limit position cover, the utility model discloses through torsion spring + buffer and realizes the automatic reset of door leaf, and through increasing buffer, the resilience of door is reduced, prevents the back and forth movement of door leaf in the middle position, improves security.

This application belongs to the field of fiber drawing machine technology and discloses a reciprocating multi-station multi-variety glass fiber ply yarn drawing machine, including a frame and a base plate. The base plate has two mounting holes, one above the other, each containing a turntable. Two sets of main shaft impeller mechanisms are slidably mounted on the turntables along the length of the frame. A tilting mechanism and a reciprocating mechanism are respectively installed inside the frame corresponding to the two turntables. The tilting mechanism drives the two sets of main shaft impeller mechanisms on the turntables to switch between working and standby positions. The reciprocating mechanism drives the main shaft impeller mechanism in the working position to slide along the length of the frame. A forced yarn splitting mechanism, a yarn blocking mechanism, a yarn arrangement mechanism, a water pipe mechanism, and an automatic yarn unloading mechanism are respectively installed on the frame corresponding to the two turntables. An automatic yarn feeding mechanism is slidably installed at the bottom of the frame. This application forms a dual-drawing station, which can independently carry out drawing operations without interference. It can be adapted to high-flow spindles or multiple spindles to increase yarn production and reduce the floor space of the production line.

This utility model discloses an integrated injection molding device for a corner window assembly, comprising: an injection molding machine, a front and rear positioning mechanism disposed on the front of the injection molding machine, and a clamping mechanism, the clamping mechanism including a cylinder, the cylinder being fixedly connected to both sides of the injection molding machine, a lifting block being fixedly connected to the top of the cylinder, and a drive shaft being fixedly connected to the front of the lifting block. This utility model, by setting the clamping mechanism, can position the sides and top of the injection mold, preventing the injection mold from tilting or moving left and right. By setting the front and rear positioning mechanism, the injection mold can be positioned front and back, preventing the injection mold from moving back and forth. During injection molding, the mold will not shake, avoiding separation of the mold from the discharge port, facilitating user operation, and ensuring normal use.
