Aiming at the bumper structure,the anti-shrinkage mark mechanism was designed in the injection mould.It could realize anti-shrinkage mark and plastic material reduction from the inside flanging of the two ends in the bumper,while the traditional bumper injection mould cannot real-ize it.The mechanism could effectively reduce the shrinkage marks caused by the flanging of both ends in the bumper,improve the appearance quality of the moulded plastic parts,and reduce the production cost of plastic parts and manufacturing costs of mould.
