Twisting and bending mold for blade

Abstract

The invention relates to a twisting and bending mold for a blade. The twisting and bending mold comprises an upper mold base, a lower mold base, guide columns and guide sleeves, wherein the guide columns and the guide sleeves are used for connection between the upper mold base and the lower mold base. In addition, the twisting and bending mold also includes an upper fixation plate fixedly connected with the upper mold base, a lower fixation plate fixedly connected with the lower mold base, a pressing block arranged at the center of the upper fixation plate, a support block arranged right belowthe pressing block, and a plurality of torsion mechanisms. The support block is embedded in the lower fixation plate movably; the upper end surface of the support block extends out of the upper end surface of the lower fixation plate and a first groove for installing an unloading spring is formed in the lower end surface. The torsion mechanisms include upper torsion units and lower torsion units;and the lower torsion units are arranged right below the upper torsion units after being rotated at 180 degrees. The twisting and bending mold has advantages of high production efficiency, low material consumption and good product quality and the like. The mold has a compact structure; the workpiece shedding from the mould becomes smooth; the operation is done conveniently; the mold is used safely; the economical and energy-saving effects are good; and mass production is realized.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a torsion mold for blades, and is especially suitable for the torsion mold for special small motor blades. Background technique [0002] Most of the current injection molding blades are used in electronics, small mechanical equipment, and household use. The requirements are small size and light weight to achieve the goal of power saving and rapid heat dissipation. However, the application is limited to small equipment, and the heat dissipation capacity is limited. Long-term use In the middle, the wear is serious and the heat dissipation capacity is reduced, so it cannot be applied to medium-sized or large-scale mechanical equipment. Cast blades, to a certain extent, are particularly popular for a period of time. With the development of the foundry industry, the precision of cast parts is also gradually increasing. They are widely used in medium-sized mechanical eq...
