Adjustable mould for automobile wheel trim

Abstract

The utility model relates to an adjustable mould for an automobile wheel trim, which comprises a mould base plate, a positioning block group mounted on the mould base plate, and a supporting block group mounted on the mould base plate and propped against the positioning block group, the positioning block group is used for pre-positioning the position of the wheel trim, and the supporting block group is used for supporting and fixing the wheel trim. The positioning block set and the supporting block set are fixed to the tire mold bottom plate through bolts according to the shape of a wheel trim, positioning blocks of the positioning block set are in an L shape, and the bottom edge and the side edge of each supporting block of the supporting block set abut against the inner side of the L-shaped edge of the corresponding positioning block for positioning. The mold has the advantages that the positioning block group and the supporting block group are mounted on the mold bottom plate in a split manner, so that the problem that the adjustment amount cannot be reserved in the conventional single mold is solved. And moreover, the assembling flexibility of the mould is improved, and the clearance surface difference of wheel brow inner and outer plate products needing to be changed is particularly excellent. The required relative position of the wheel eyebrow inner plate and the wheel eyebrow outer plate is achieved by adjusting the position degrees of the supporting block and the positioning block.

Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, in particular to an adjustable tire mold for automobile wheel arches. Background Art

[0002] In the original technology, during the process of pressing the inner and outer panels of the fender with the upper and lower jigs, the relative positions of the inner and outer panels cannot be adjusted by the jig. The jig blocks of the original jig do not have the adjustment function and cannot correct the deformed products. It is more difficult to adjust the gap surface difference involving the relative positions of the inner and outer panels, and it can only be adjusted by positioning the product structure itself, and the adjustment consistency is poor. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide an adjustable tire jig for automobile wheel arches, which is used to perform corrective adjustment on product deformation through the tire blocks of the tire jig. In some cases where there is a need to adjust the relative positions of inner and outer plates, the gap and face difference of the product can also be corrected and adjusted through the tire blocks of the tire jig. After adjustment, the gap and face difference can meet the size requirements, so as to overcome the shortcomings of the above-mentioned prior art.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A tire mold with adjustable wheel brows for automobiles comprises: a tire membrane base plate, a group of positioning block groups installed on the tire membrane base plate, and a support block group installed on the tire membrane base plate and supported on the positioning block group, wherein the positioning block group is used to pre-position the wheel brow, and the support block group is used to support and fix the wheel brow. The positioning block group and the support block group are fixed to the tire membrane base plate by bolts according to the shape of the wheel brow. The positioning block of the positioning block group is L-shaped, and the bottom edge and side edge of the support block of the support block group are supported on the inner side of the L-shaped edge of the positioning block for positioning.

[0006] As a preferred embodiment of the utility model, the positioning block group is composed of a first positioning block, a second positioning block, a third positioning block, a fourth positioning block, a fifth positioning block, a sixth positioning block, a seventh positioning block and an eighth positioning block which are sequentially installed on the fetal membrane bottom plate from left to right, and the support block group is composed of a first fetal membrane support block, a second fetal membrane support block, a third fetal membrane support block, a fourth fetal membrane support block, a fifth fetal membrane support block, a sixth fetal membrane support block, a seventh fetal membrane support block and an eighth fetal membrane support block which are sequentially installed on the fetal membrane bottom plate from left to right.

[0007] The advantages and positive effects of the utility model are as follows: the positioning block group and the support block group of the utility model are installed on the tire membrane bottom plate in a split form to solve the problem that the existing single tire cannot reserve the adjustment amount. It also increases the flexibility of the tire assembly, which is particularly good when encountering some products that need to change the gap surface difference between the inner and outer panels of the wheel eyebrow. By adjusting the position of the support block and the positioning block, the required relative position of the inner and outer panels of the wheel eyebrow is achieved. It solves the problem that the original tire design cannot meet the product shrinkage deformation. BRIEF DESCRIPTION OF THE DRAWINGS
