The invention discloses an automatic reaming device for the center hole of a disc saw blade, and belongs to the technical field of metal saw blade processing machinery. The automatic reaming device comprises a base, a vertical drilling machine, a material feeding mechanical arm translation driving mechanism, a material receiving mechanical arm translation driving mechanism, a material feeding lifting mechanism, a material receiving lifting mechanism, a reaming saw blade carrying mechanism, a material feeding mechanical arm and a material receiving mechanical arm. The vertical drilling machine is provided with a drilling machine worktable and a reamer; the material feeding mechanical arm translation driving mechanism and the material receiving mechanical arm translation driving mechanism are arranged on the base and on the left end and the right end of the base in the length direction; the material feeding lifting mechanism and the material receiving lifting mechanism are arranged on the back side of the left end of the base and the back side of the right end of the base; the reaming saw blade carrying mechanism is arranged on the drilling machine worktable; the material feeding mechanical arm is in sliding fit with the upper part of the left end of the base and is in connection with the material feeding mechanical arm translation driving mechanism; the material receiving mechanical arm is in sliding fit with the upper part of the right end of the base and is in connection with the material receiving mechanical arm translation driving mechanism. The equipment input quantity is reduced, and the labor resource is saved; the operation safety of workers is ensured; the operation intensity is reduced; the reaming quality of the center hole of the disc saw blade is ensured, and flaws are eradicated; mechanized automatic reaming is realized, the environment of a workplace where the workers work is standard and orderly.

The invention discloses a shooting device and method as well as a mobile terminal. The device comprises an acquisition unit, a correction unit, a synthesis unit, a display unit and an indication unit, wherein the acquisition unit is used for periodically acquiring a first image by adopting a first camera during shooting preview, and simultaneously acquiring a second image by adopting a second camera; the correction unit is used for correcting the first image according to a preset first parameter, used for correcting images, of the first camera, and correcting the second image according to a preset second parameter, used for correcting images, of the second camera; the synthesis unit is used for synthesizing the corrected first image and the corrected second image into a third image; the display unit is used for jointly displaying a preset photo and the third image in a preview window; and the indication unit is used for indicating a user to adjust the position of the scene of the third image in the preview window according to the relative position relation between the scene in the preset photo and the scene in the third image displayed by the display unit.

The invention discloses a novel injection mold. The novel injection mold comprises an upper mold, a lower mold, positioning pins, positioning holes, springs, an inner baffle plate and an outer baffle plate, wherein the positioning pins are arranged at two short side edges of the upper mold; the positioning holes are formed in two short side edges of the lower mold; the springs are arranged between the positioning holes in the side edge of the lower mold; the inner baffle plate is arranged at the inner edge of the lower mold; the outer baffle plate is arranged at the outer edge of the upper mold; air vent holes are formed in the middle of the upper mold; a movable pin is arranged in the middle of each air vent hole; a sealing ring is arranged at the bottom end of each movable pin. The novel injection mold is simple in structure and reasonable in design; by virtue of the air vent holes, when the mold is internally heated in a closing process of the upper mold and the lower mold, air can be vented from the air vent holes, so that the pressure of internal air and external air is consistent, and the defects of a product are prevented; when raw materials are completely filled into the mold, the movable pins are blocked to prevent the raw materials from being leaked; by virtue of the inner baffle plate and the outer baffle plate, gaps of the mold are reduced, so that redundant parts of the raw materials cannot be leaked, and waste is reduced. The novel injection mold is suitable for energetic popularization and application.
