Technical Field
The invention relates to the technical field of automobile part manufacturing, in particular to a mould for bending and processing a handle of an adjustable automobile sun-shading curtain.
Background
The automobile sun-shading curtain can be used for effectively shading the sunlight of the front windshield and the side rear windshield of an automobile. At present, the handle of the automobile sun-shading curtain is bent mainly by iron mold processing operation. But the crooked radian of swage is fixed, all needs the milling die radian when the hardness change of handle material is great or the crooked radian of handle changes, and the bending work load of car sunshade screen handle is big just loaded down with trivial details like this, and the operation is extremely inconvenient.
Chinese patent CN204673862U, entitled a mold for a universal handle of an automobile, which comprises a front template, an upper T-shaped block, an upper template, a front mold core, a rear mold core, a mold base, a positioning pin, a limiting block and a positioning block, wherein an inclined hole matched with the front mold core is arranged in the upper template; the front mold core rotates in the inclined hole of the upper mold plate; the rear mold core is fixed with the mold base through screws; the front template is fixedly connected with the upper T-shaped block through screws. The mould is suitable for plastic parts, can avoid parting lines on the surface of the plastic part, but is not suitable for bending the handle of the sun-shading curtain.
Disclosure of Invention
The invention aims to provide a mould for bending a handle of an adjustable automobile sunshade curtain, which aims to solve the problems that the existing bending processing of the handle of the automobile sunshade curtain adopts an iron mould, the mould needs to be milled when the hardness of the handle of the automobile sunshade curtain is changed greatly or the radian is changed, and the operation is inconvenient.
The invention provides the following technical scheme:
a mould for bending and processing a handle of an adjustable automobile sun-shading curtain comprises a mould base, wherein the mould comprises an upper mould base which can be driven by a power device to lift, a bending forming part connected with the upper mould base, a bendable upper mould arranged below the bending forming part, a bendable lower mould matched with the upper mould for use, and a plurality of lower mould fixing blocks for supporting the lower mould;
the two ends of the upper die base are connected with the two ends of the upper die through elastic jacking pieces;
the lower edge of the bending forming part is in a convex arc shape, and during bending processing, the middle part of the lower edge firstly presses the upper die;
the lower die fixing blocks are arranged on the die base and arranged on two sides of the middle part of the lower die.
The mould of the invention adopts a bendable upper mould and a lower mould, and two ends of a handle are provided with elastic jacking pieces which are connected with an upper mould base. When the handle of the automobile sun-shading curtain is bent, the handle to be processed is placed on the lower die, and then the upper die base is driven by the power device to drive the bending forming part and the upper die to descend. When the upper die is attached to the handle of the automobile sunshade curtain and matched with the lower die, the upper die cannot move downwards any more, the bending forming part continues to move downwards and pushes against the upper die, the upper die is bent under the pushing of the bending forming part, and the lower die fixing blocks are dispersed on two sides of the middle part of the lower die, so that the middle part of the lower die is short of support, and the upper die and the lower die are bent under the pushing of the lower die, and the handle of the automobile sunshade curtain is bent. Meanwhile, the two ends of the upper die and the upper die base are pressed by the elastic pressing piece, the elastic pressing piece retracts in the bending process of the upper die and is always in a state of pressing the upper die, so that the two ends of the upper die are pressed against the lower die, the two ends of the upper die are prevented from being excessively tilted to be separated from the automobile sunshade curtain handle, the bending radian of the automobile sunshade curtain handle is ensured to be the same as the bending radians of the upper die and the lower die, and therefore when the automobile sunshade curtain handle is bent to the required radian, for example, the upper die is attached to the lower edge of the bending forming part, the upper die base stops pressing down, then rises to be separated from the automobile sunshade curtain, and the bending processing of the. Because the upper die and the lower die can be bent, the bending radian can be changed along with the requirements of the hardness and the radian of the handle of the automobile sun-shading curtain, the milling is avoided, the operation is flexible, and the working efficiency is high.
