Description

Technical Field

[0001] The utility model belongs to the technical field of automobile interior decoration manufacturing, in particular to a flame processing anti-drilling fire shielding device. Background Art

[0002] In the field of automotive interior manufacturing, the injection molded skeleton needs to be flame treated before the foaming process to increase its surface dyne value so that it can effectively bond with the foaming layer. However, since leakage is inevitable in the foaming process, if these leaking areas are also treated during the flame treatment process, the subsequent manual cleaning of the residual foaming material will be very labor-intensive and time-consuming. Therefore, the non-foamed area of ​​the skeleton must be shielded during the flame treatment process to reduce labor intensity and labor costs. Existing shielding devices all use hard baffles, which are difficult to effectively form a sealing structure with the parts, so they cannot effectively prevent flame penetration.
