Embodiment 1

[0028] combine figure 1 and figure 2 As shown, the chassis rocker arm part mold disclosed in the embodiment of the present invention includes a mold base 1, a first module 2, a second module 3 and two third modules 4, a first module 2, a second module 3 and two third die sets 4 are fixed on the upper surface of the die base 1 in sequence along the length direction of the die base 1 at intervals. The length direction of the first module 2, the second module 3 and the two third modules 4 is perpendicular to the length direction of the mold base 1. The first module 2, the second module 3 and the two third modules The width direction of the group 4 is parallel to the length direction of the die base 1 . It should be noted that the two ends of the chassis rocker arm part in this embodiment are respectively provided with a groove and a convex edge, and the blanks of the chassis rocker arm part can be connected end-to-end in sequence during production, that is, the latter chassis ...

Abstract

The invention provides a chassis rocker arm part mold, which includes a mold base and a first die set, the first die set is fixed on the upper surface of the die set, and the first die set comprises a first die core and two first positioning columns, The first mold core is fixed on the upper surface of the mold base in parallel, and both ends of the first mold core in the longitudinal direction are provided with first positioning grooves; Set in the two first positioning grooves, the end surface of one first positioning column facing the first mold core is provided with a convex edge along the height direction of the first positioning column, and the end surface of the other first positioning column facing the first mold core is along the first positioning column. The height direction of the positioning column is provided with grooves, and one end of the rocker arm part of the chassis is also provided with grooves and ridges, so as to match the grooves and ridges on the two first positioning columns. There is no need for debugging and positioning, and positioning is carried out directly through the grooves and ridges of the rocker arm parts of the chassis, which avoids the generation of accumulated errors and has good practicability.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a chassis rocker arm part mold. Background technique [0002] At present, the technical solution used for the chassis rocker arm parts is cold stamping, with a total of 11 processes: blanking, forming, punching, flipping, flipping, trimming, flanging, flanging, side shaping, hole calibration, side Flanging. Due to the particularity of the part structure, many places are not conducive to the design of the mold structure, and the accuracy of the parts requires that the roundness of the turning hole is within 0.2, and the coaxiality is within 0.3, but the parts process has as many as 11 processes, and each process is practical A lot of dimensional errors will accumulate during debugging and production. When the final product is produced, the accumulation of errors will be even greater. With other dimensions, it will bring great challenges to manufacturing. [0003] Moreover, af...
