The invention provides a forming mold and method of a large-curvature open thin-walled structure composite. The forming mold is of a half-closed type single-cavity lateral-pressurization structure andcomprises a male mold, a female mold, an upper cover plate, lateral stop blocks, lateral sliding blocks, lifting rings and fastening bolts. By the adoption of the forming mold and method of the large-curvature open thin-walled structure composite, the quality problems of product deformation, dimension deviation, surface defects and the like which are prone to happen in the mold pressing process of a large-curvature open thin-walled composite product are solved, the mold structure is light, simplified, economical and durable, the forming mold is suitable for various pressure devices and achieves one-off formation of a large-curvature open thin-walled structure, the work amount of post-treatment is small, and the yield is high.

The invention discloses a detection method and device for a drivable area, which uses all contact points between target objects and the ground in the acquired current road image as marked points for marking, and connects all marked contact points to obtain a non-closed polyline , mark the object category corresponding to each target object in the non-closed polyline, and obtain the target road image containing the object category labeling result, input the target road image into the drivable area semantic segmentation model, and obtain the predicted pixel point category of each pixel Information, according to the predicted pixel category information and location information of each pixel, filter and cluster all the marked contact points to obtain different types of contact point sets, based on the contact point set, determine the drivable area in the current road image. When the present invention recognizes the drivable area, only the contact point between the target object and the ground is marked as a marked point, thus saving a lot of marking work and shortening the marking time.

The invention discloses equipment for directly growing a sapphire fairing. The equipment comprises a rack, a furnace body, a crucible and a capillary guide mold, wherein a rotating component is arranged below the rack and comprises a fixed frame, a rotary motor and a drive rod; the crucible can be driven by the rotary motor to rotate; a support is arranged above the furnace body; a longitudinal moving mechanism and a horizontal moving mechanism are arranged on the support; the horizontal moving mechanism is connected with the longitudinal moving mechanism; a torque motor is arranged on the horizontal moving mechanism; a seed rod fixed frame is arranged on an output shaft of the torque motor; the capillary guide mold is vertically arranged in the furnace body and is installed on the crucible via a fixed clamp; the lower end of the capillary guide mold extends in the crucible; a through hole through which a seed rod can pass is formed in the top of the furnace body; and the seed rod can move horizontally in the through hole. The equipment can effectively reduce the processing difficulty and improve the production efficiency.

The invention relates to a segmental casting method for a special-shaped steel casting of a subway bogie. The middle part of the upper rib plate of the casting is divided into upper and lower parts, and the upper type is divided into segments by the center of a circular boss; the pouring system consists of an inner runner from below The center of the rib plate enters the mold cavity; it is set on the machined surface and other positions; the sand mold of the lower outer mold, the sand mold of the upper outer mold, the sand filling sand core of the gate and the sand filling sand core of the section are made of water glass ester hardened sand; After the mould, the furnace material is smelted into a pouring melt, and the casting is poured, and the melt enters from the gating system; cooling, opening the box to shake off the sand, and cutting the pouring riser to form the casting blank. The present invention adopts the casting process of parallel splitting of the rib plate to ensure the compact internal quality of the whole casting and improve the product stability, and the riser is arranged on the machined surface, which greatly reduces the post-processing workload and improves the work efficiency; The segmental casting process forms the isolated part of the upper mold of the casting through sand filling sand cores, reduces the overall height of the upper mold, reduces the amount of molding sand, and improves production efficiency at the same time.
