detailed description

The technical scheme of the utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments.

As shown in Figures 1-5, a flatness shaping mold described in this embodiment includes an upper mold base 1, an upper template 2, a lower template 3 and a lower mold base 5, and the upper template 2 is fixed on the upper mold base. The lower surface of the mold base 1, the lower template 3 is placed on the upper surface of the lower mold base 5, the two sides of the lower template 3 are provided with strip-shaped fixing blocks 7, the lower surface of the upper template 2 Several protruding beading bars 21 are arranged in parallel, and the upper surface of the lower template 3 is provided with grooves 31 corresponding to the beading bars 21 for accommodating workpieces.

The fixed block 7 is fixed on the upper surface of the lower mold base 5, and the upper surface of the fixed block 7 is lower than the upper surface of the lower template 3; the lower template 3 is limited by the fixed block 7, and the The lower template 3 is fixed between the two fixing blocks 7 to prevent left and right movement.

The bottom of the groove 31 is stepped, including a shaping groove 311 and a limiting groove 312. The bottom of the shaping groove 311 is lower than the bottom of the limiting groove 312, and the workpiece is placed in the shaping groove 311; The surface to be shaped of the workpiece is in close contact with the bottom of the shaping groove 311 , and the flatness of the surface to be shaped is carried out through the plane at the bottom of the shaping groove 311 .

The lower surface of the bead 21 is stepped, including a fixed surface 211, a limiting surface 212 and a stepped surface 213, the limiting surface 212 is lower than the fixed surface 211 to form a step; the fixing of the bead 21 when pressing down The step formed by the surface 211, the limiting surface 212 and the step surface 213 just embeds the workpiece and conflicts with the workpiece; the shape of the lower surface of the bead 21 matches and closely contacts the shape of the upper surface of the workpiece, and the workpiece is evenly stressed during shaping, preventing out of shape.

The side where the fixing surface 211 is connected to the step surface 213 is in conflict with the top of the workpiece, and the other side extends above the upper surface of the lower template 3; the side where the limiting surface 212 is connected to the step surface 213 is in contact with The workpieces are in conflict, and the other side extends to the top of the bottom of the limiting groove 312; the fixing surface 211 and the limiting surface 212 are used to press the workpiece and apply force to the workpiece, and at the same time, the upper surface of the lower template 3 The downward pressure of the fixing surface 211 is limited, and the downward pressure of the fixing surface 211 is limited through the bottom of the limiting groove 312, so as to prevent the upper surface of the workpiece from being squeezed and deformed.
