Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic surface treatment, specifically relates to a car injection molding piece flame treatment device. BACKGROUND

[0002] Flame treatment is the process of using strong oxidizing flame to oxidize the surface of plastic. The flame contains a large number of ions and has strong oxidizing property. In the high temperature state, it reacts with the treated plastic surface to form a layer of charged polar functional groups, thereby improving the surface energy.

[0003] Chinese patent publication No. CN221090041U discloses an automobile injection molding piece flame treatment device, which comprises a bottom plate, a clamping mechanism for fixing the plastic on the top of the bottom plate, a support frame fixed at one end of the bottom plate away from the clamping mechanism, a plastic burning mechanism for surrounding spraying treatment of the plastic part, and an adjusting mechanism. The rotating frame is alternately rotated in forward and reverse directions to gradually push the wedge-shaped notch of the guide rack with the actuating head, and then the guide rack drives the sliding plate and the support to send the injection molding part into the rotating frame, and then the injection molding part is treated by flame. The three telescopic rods inside the rotating frame and the flame spraying seat are used to surround the injection molding part for spraying treatment, and the moving frame is used to move the rotating seat and the connecting rod to push the flame spraying seat, so as to adjust the distance between the flame spraying seat and the injection molding part according to the shape of the injection molding part.

[0004] In the prior art disclosed above, the clamping seat can be used to clamp the automobile injection molding part and send it to the flame spraying seat for flame treatment, but the clamped part of the automobile injection molding part will be covered, so that the flame cannot cover it, and the clamping direction of the automobile injection molding part needs to be changed. After the injection molding part is treated by flame, the temperature of the injection molding part is high, and manually taking the injection molding part to adjust the clamping direction will have the risk of scalding, and waiting for the injection molding part to cool down will prolong the processing time.
