Based on the design of a multifunctional injection mold for a new type of curtain hanging chain,a multifunctional three plate injection mold was innovatively designed based on the method of in mold assembly to meet the injection molding requirements of six combined states of plastic parts.This mold was used for the injection production of six assembled states of the ring hanging chain.In the mold,the mold cavity was composed of six independent single ring mold cavities,and the cavities between the two rings form a 90° vertical cross shaped ring sleeve ring state.This could achieve the production requirements of assembling ring chains in six assembly states by controlling the opening and closing of the gates of each independent mold cavity.To achieve independent opening and closing control of 6 mold cavity gates,a plug type gate opening and closing control mechanism was designed.The mechanism consists of 6 plug plates,1 socket,and 1 pressure block,and 6 screws were used to lock the stop position of the plug plate.The mold could achieve a total of 6 assembly states of single ring,2 ring,3 ring,4 ring,5 ring,and 6 ring for direct assembly production in the mold,which had good design reference value.
