Riveting device for automobile heat insulation part mold

[0017]Examples:

[0018]Seefigure 1 withfigure 2, A riveting device for automotive heat insulation molds, comprising an upper mold part and a lower mold part connected to each other,

[0019]The lower mold part includes an insert block 1, a pressing plate 2, a screw 3, a screw plug 4, a spring 5, a die 6 and an ejector pin 7; the insert block 1 is provided with a hole, the screw plug 4, the spring 5, and the recess The mold 6 and the top pin 7 are arranged in the hole from bottom to top, and the insert block 1 is also provided with a mounting groove for installing the pressure plate 2 and a mounting screw hole for installing the screw 3, that is, the pressure plate 2 is installed In the mounting groove of the insert 1, the concave mold 6 is also provided with an anti-rotation surface 61, and the pressure plate 2 is matched with the anti-rotation surface 61; the pressure plate 2 is matched with the anti-rotation surface 61 of the concave mold 6 In order to achieve the problem of anti-rotation of the concave mold 6, especially to solve the problem of anti-rotation of the concave mold 6 in the undulating area of ​​the profile, then the whole lower mold part of the riveter is locked on the insert 1 of the lower mold part by the screw 3; The insert 1 of the lower mold part is assembled on the lower mold base to form the lower mold base assembly;

[0020]The upper die part includes a riveting punch 8, a fixing plate 9 and a backing plate 10. The fixing plate 9 is provided with a fixing hole for connecting with the rear end of the riveting punch 8, and the backing plate 10 is connected At the bottom of the fixed plate 9, the front end of the riveting punch 8 is connected with the top pin 7; the outer circle of the riveting punch 8 described in the upper die part of the riveter and the fixing hole of the fixed plate 9 adopt a transitional fit, Then set the backing plate 10 at the bottom to facilitate the adjustment of the depth of the riveting device in the later period; the riveting punch 8, the fixing plate 9, and the backing plate 10 are assembled with the upper mold base by screws and pins to form an upper mold base assembly;

[0021]This application uses the riveting punch 8 and the die 6 of the upper and lower die to achieve the effect of riveting the upper and lower layers of the products in the upper and lower layers of the product in the punching waste area of ​​the product, thereby solving the problem of the product when the riveting device is not added. The phenomenon that the upper and lower aluminum parts of the part are scattered after the trimming is completed. This greatly solves the flanging process caused by the scattering of the upper and lower products, and the repeated adjustment of the flanging gap, as well as the product quality problems such as the wrong flanging and the poor fastening of the hemming. Through the punching set in the hemming process, the riveting position of the punching waste area is cut off, so that no surface features that are inconsistent with the product will not be left on the product. After the hemming is completed, the parts will not be scattered because the circumferential position has been buckled. Through the inspection of the preliminary project, the fitter debugging time of similar parts has been shortened by 40 hours, and the parts using the riveter structure have also been highly conscientious by customers. The company has undertaken similar parts for many times. Therefore, through the structure of the riveting device for automobile heat insulation parts, it can reduce the debugging workload, shorten the mold manufacturing cycle, and reduce the cost of mold manufacturing, and win the trust of customers while further occupying market share
