Background
Vibration friction welding is a friction welding process in which the parts being welded are abraded together under pressure until the contact surfaces reach a sufficiently molten state by the generated frictional and shear heat. When the set welding depth is reached (measured by the linear sensing ruler), the relative movement is stopped, and the welding line is cooled and solidified in the pressure maintaining stage.
In the vibration friction welding process, a vibration friction welding mold is used, the upper plastic product and the lower plastic product are positioned and supported, and then the two products are welded together by means of energy provided by vibration friction welding equipment. Before welding, an upper product needs to be placed on an upper die, and a lower product needs to be placed on a lower die. In prior art, go up the mould and can prevent that the product from droing with vacuum chuck absorption product usually, when the mould die sinking was gone up to the back of the welding, need let the product that the welding was accomplished stay the lower mould, if the product is taken up by last mould, then need increase cylinder hold-down mechanism.
