The utility model discloses a mold core-pulling structure, which relates to the technical field of molds, and comprises a bottom plate and a core-pulling mechanism arranged on the bottom plate, the core-pulling mechanism comprises a first sliding block group and a second sliding block group which are arranged on the bottom plate, one side of the first sliding block group is respectively and fixedly provided with a middle cylinder and two groups of inclined plates, and the other side of the first sliding block group is fixedly provided with a second sliding block group. A sliding plate is arranged at one end of the inclined plate in a sliding mode, and two sets of fixing plates are fixedly arranged on one side of the second sliding block set. According to the core-pulling mechanism, a plurality of parts in a traditional core-pulling structure are integrated on the bottom plate through a layered linkage structure of the first sliding block group and the second sliding block group, so that the structure is compact, the space is saved, the utilization rate of the internal space of the mold is remarkably improved, and the design requirements of miniaturized and precise molds are met; and integral demolding is achieved, and it is ensured that parts are free of residues and damage.

This application relates to a feeding control method, device, and components for a shot blasting machine, comprising the following steps: S1, determining the position of the hopper body; if the position and state of the hopper body can be determined, proceed to step S2; otherwise, proceed to step S3; the hopper body includes an empty state and a loaded state; S2, based on the position of the hopper body, continue with subsequent operation steps; S3, manual intervention, sending the hopper body to the designated position, inputting the position program to confirm the position of the hopper body, and then proceeding to step S2 after confirmation. This invention is rationally designed, compact in structure, and easy to use.

The utility model belongs to low altitude flight product technical field provides a kind of detachable low altitude aircraft transparent part, including transparent piece, sealing strip and fuselage, sealing strip is located between transparent piece and fuselage and is used to install seal between transparent piece and fuselage, there is detachable connecting structure between transparent piece and fuselage, transparent piece is connected and installed with fuselage by detachable connecting structure.The utility model's advantage lies in adopting sealing ring bolt mounting structure, instead of glue structure, simple installation, small stress, substantially reduce production working hour cost, improve the production efficiency and pass rate of product, sealing strip structure also improves transparent piece and fuselage cooperation gap and appearance effect, also facilitate post-period disassembly and maintenance.
