Abstract: A low-pressure mold for improving performance of spokes of an aluminum wheel. The mold is characterized in that cooling air holes in a bottom mold are moved for 10 mm in outwards; heat-insulation grooves are formed in positions, 5 mm from the cooling air holes, of a back cavity of the bottom mold, and are 8 mm from the surface of a cavity; and the width of each heat-insulation groove is set to 8 mm. A circumference arrangement range of the heat-insulation grooves needs to be larger than the widths of the spokes, and the number of the heat-insulation grooves is defined by the number of the spokes. Heat-preservation asbestos is arranged in each heat-insulation groove, thereby further strengthening heat-insulation and heat preservation functions. One air hole is added based on the prior art, thereby increasing the cooling area and improving the cooling intensity.

Abstract: A right angle touch gauge of the present application includes a fixing block, a floating column, a spring, a measuring column, a measuring sleeve and the like. In use, round head of top end of the floating column is in contact with bottom surface of work piece. The floating column is compressed downward when it touches high surface of the bottom surface of the work piece, the measuring column is compressed to right by matching lower cone of the floating column and left cone of the measuring column, and it may be found whether height difference between high surface and low surface of the bottom surface of the work piece is qualified by observing whether end edge of the right cylinder of the measuring column is placed between steps of right end surface of the measuring sleeve.

Abstract: The present invention discloses a variable size wheel deburring device, which is composed of a lower lifting system, a central brush driving system, a brush system I, a brush system II and a clamping driving system. When used, the servo electric cylinder II, through the guiding rail II, causes the left and right rollers to clamp the lower wheel rim of the wheel; and the servo motor I can achieve the rotation of the clamped wheel by the pulley I, the pulley II and the synchronous belt I. The device according to the present invention in use can not only realize the burr removal of the wheel center hole, the flange root corner, the spoke edge and the rim corner, but also can adapt to wheel types of different size.
