AI Technical Summary
[0003]由于汽车后地板板材较厚,且翻边轮廓复杂,在进行翻边整形时,板料对凸模会产生巨大的反向作用力,即侧向力,这个侧向力会传递到两侧的导向块上,由于导向块的主要功能是保证滑动精度,其设计更侧重于低摩擦和精确导向,而非承受巨大的单向压力,在长期、大批量的生产过程中,持续的侧向冲击载荷会导致迅速磨损,使得配合间隙增大,从而在作业时发生颤动或位移,使得翻边后的零件尺寸不稳定,轮廓精度下降,严重时甚至会产生零件起皱或扭曲等质量缺陷,磨损的导向块需要频繁调整或更换,模具停机维修时间长,影响了生产效率和成本控制
[0011]本实用新型的有益效果是:本实用新型一种用于汽车后地板翻边的整形模具,该整形模具具有抗侧结构,解决了由于侧向力完全由导向块承受导致的易磨损、模具精度不稳定的问题,从而能够提高模具的耐用性和精度稳定性。

Abstract
Description
Technical Field
[0001] This utility model relates to the field of automobile manufacturing, and in particular to a shaping mold for flanging the rear floor of an automobile. Background Technology
[0002] In automobile body manufacturing, the rear floor is an important structural and functional component. Its perimeter is usually designed with complex flange structures to increase rigidity, connect other components, and eliminate sharp edges.
[0003] Because the rear floor panels of automobiles are thick and have complex flanging contours, the sheet metal exerts a huge reverse force on the punch during flanging, i.e., lateral force. This lateral force is transmitted to the guide blocks on both sides. Since the main function of the guide blocks is to ensure sliding accuracy, their design focuses more on low friction and precise guidance rather than bearing huge unidirectional pressure. In long-term, high-volume production, continuous lateral impact loads will cause rapid wear, increasing the fit clearance. This will cause vibration or displacement during operation, resulting in unstable dimensions and reduced contour accuracy of the flanged parts. In severe cases, it may even cause quality defects such as wrinkling or twisting of the parts. Worn guide blocks need to be frequently adjusted or replaced, and the mold downtime for maintenance is long, affecting production efficiency and cost control. Utility Model Content

[0016] The preferred embodiments of the present invention will be described in detail below so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0017] according to Figures 1 to 3A forming mold for flanging the rear floor of an automobile includes an upper mold base 1 and a lower mold base 2. The upper mold base 1 is disposed on the lower mold base 2. A forming component is installed between the upper mold base 1 and the lower mold base 2. The forming component is equipped with an anti-lateral structure to resist lateral forces, which solves the problems of easy wear and unstable mold precision caused by the lateral forces being entirely borne by the guide block 8, thereby improving the durability and precision stability of the mold.
[0018] The molding assembly includes a pressing assembly and a driving assembly. The pressing assembly is installed at the bottom of the upper mold base 1, and the driving assembly is located at the top of the lower mold base 2. The anti-side structure includes two parts, which are respectively installed on the pressing assembly and the driving assembly.
[0019] The pressing assembly includes a pressing plate 3 and an upper mold core. The pressing plate 3 is connected to the bottom of the upper mold base 1. The upper mold core is disposed at the bottom of the pressing plate 3 and is provided with a concave mold that cooperates with the rear floor.
[0020] The driving assembly includes a driving plate 4 and a lower mold core. The driving plate 4 is connected to the top of the lower mold base 2. The lower mold core is disposed on the top of the driving plate 4 and has a punch that cooperates with the rear floor.
[0021] The anti-lateral structure includes a backing plate 5 for resisting lateral forces and a backing pad 7 that cooperates with the backing plate 5. The backing plate 5 is installed on one side of the pressure plate 3, and the backing pad 7 is installed on the drive plate 4 on the side corresponding to the backing pad 7. Two backing blocks 6 are provided at the bottom of the backing plate 5. The backing blocks 6 extend downward to the side of the drive plate 4 and contact the backing pad 7. By cooperating with the backing blocks 6 and the backing pad 7, the mold's resistance to lateral forces is improved, thereby improving the mold's durability.
[0022] The upper mold base 1 is symmetrically provided with guide blocks 8 on both sides. The guide blocks 8 cooperate with the guide grooves 9 on both sides of the lower mold base 2. Through the cooperation of the guide blocks 8 and the guide grooves 9, when the mold is closed, the guide blocks 8 will enter the guide grooves 9 first, guiding the upper and lower molds to close along the preset path, ensuring that the upper and lower molds will not be misaligned, thereby producing products with accurate dimensions and correct shape.
[0023] A plurality of sliding surfaces 10 are provided between the guide block 8 and the guide groove 9. The sliding surfaces 10 can reduce motion resistance, prevent "biting" or "scratching" phenomena, ensure smooth and stable mold closing action, thereby resisting wear caused by long-term reciprocating motion and preventing loss of guiding accuracy due to increased mating clearance caused by wear.
[0024] Compared with the prior art, the present invention provides a forming mold for flanging the rear floor of an automobile. The forming mold has an anti-side structure, which solves the problems of easy wear and unstable mold precision caused by the lateral force being borne entirely by the guide block, thereby improving the durability and precision stability of the mold.
