Detailed ways

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

As shown in FIG. 1 , it is a structural schematic diagram of the chassis side plate to be processed of the present invention. Figures 2 to 6 are structural schematic diagrams of the stamping and shaping mold for the side panel of the chassis of the present invention. the

A stamping and shaping mold for the side plate of a chassis, comprising an upper mold and a lower mold correspondingly arranged below the upper mold, the upper mold includes an upper mold base 2, an upper backing plate 3, an upper splint 4, Stop plate 5, stripper plate 6, upper mold base 2, upper backing plate 3, and upper splint 4 are connected in sequence, and upper backing plate 3, upper splint 4, stop plate 5, and stripping plate 6 are connected in sequence; the lower mold includes From bottom to top, the lower mold base 10, the lower backing plate 9, the lower template 8, the lower mold base 10, the lower backing plate 9, and the lower template 8 are connected in sequence, and the chassis side plate 100 is buckled on the lower template 8 and placed on the lower template 8 and the stripper plate 6, the lower template 8 is provided with a groove 81 aligned with the concave portion 1001 to be shaped of the side plate 100 of the cabinet, and a step hole 61 is opened in the middle of the stripper plate 6, and the step hole 61 Removable connection is provided with the step-shaped shaping plate 7 whose bottom shape is compatible with the groove 81, the shaping plate 7 forms a tight fit with the step hole 61, the step surface of the shaping plate 7 fits with the step surface of the step hole 61, and the shaping The bottom of the plate 7 protrudes from the bottom of the step hole 61. The protruding height of the shaping plate 7 is the depth of the groove 81. The edge of the bottom of the shaping plate 7 has a bevel of 45 degrees. 8 outer positioning 13, each direction is provided with two, the outer positioning 13 includes the positioning column 1301 that runs through the lower backing plate 9 and the lower template 8, and the top of the positioning column 1301 is provided with a folded edge 1302 toward the side plate 100 of the cabinet, and the folded edge The front end of 1302 is provided with an upward resisting edge 1303 , and the resisting edge 1303 extends into the accommodating groove of the stripper plate 6 and abuts against the side plate 100 of the chassis. the

The utility model is used for the stamping and shaping mold of the side plate of the case. When the shaping plate 7 is pressed on the side plate 100 of the case, the concave portion 1001 to be shaped of the side plate 100 of the case is pressed down and falls into the lower formwork. In the groove 81 of 8, at the same time, use the resisting edge 1303 of the outer positioning 13 and the surroundings of the side plate 100 of the chassis to perform positioning in 8 directions, so as to ensure that the surroundings of the side plate of the chassis will not be depressed when the concave part is pressed. The warping is deformed, and the positioning of 8 directions greatly increases the positioning points, so that the stress on the concave part 1001 is distributed to more positioning points, and the stress on each positioning point is greatly reduced, thus reducing the deformation; And the depth of the groove is used to limit the depth of the plastic surgery, and the protruding height of the plastic plate is the depth of the groove, so that when the plastic is pressed down, the height of the concave part is just the protruding height of the plastic plate, thus ensuring the plastic size , and set a chamfer angle of 45 degrees on the edge of the bottom plate of the shaping board to avoid the right-angle stamping from breaking the connection between the stamping part and the concave part, so as to ensure the yield of the side plate of the chassis after shaping; at the same time, the shaping board can be The disassembled connection is connected to the stripping plate, and the top of the shaping plate is pressed and limited by the stopper plate. When the shaping plate is stamped and worn for a long time, the shaping plate can be replaced alone without replacing the entire stripping plate, which greatly Reduce cost, the stamping and shaping structure is simple, and the production efficiency is high; and because the shaping plate 7 will be easily worn during long-term stamping, the shaping plate 7 can be made of other materials with higher strength and better performance than the stripping plate 6, It is not necessary to require the release plate 6 to also use this high-performance material, which can greatly reduce the cost. the

The upper part of the resisting edge 1303 has a 30-degree bevel, and correspondingly, the accommodating groove of the stripper plate 6 also has a 30-degree bevel. The 30-degree oblique angles are used to cooperate with each other, which can solve the over-positioning caused by the mutual contact of each surface, so as to ensure that the resisting edge 1303 can well resist the end of the side plate of the chassis. the

Preferably, the upper mold further includes an upper cover plate 1 connected with the upper mold base 2, and the upper cover plate 1 is connected with the press. Lower die also comprises lower pad 11 and lower supporting plate 12, and lower supporting block 11 is positioned at the bottom of lower mold base 10, and lower supporting plate 12 is positioned at the bottom of lower pad 11, and lower supporting plate 12, lower pad 11 and lower mold The seat 10 is connected, and the lower pallet 12 is connected with the press. The upper cover plate 1 and the lower supporting plate 12 are respectively connected with the press to realize stable placement, and the punching action of the utility model is realized by means of the pressure of the press. the
