Abstract: This article analyzed the technological characteristic of a printer shell and introduced the structural design and operating process of the injection mould for this part. To fabricate such a mould, two side core-pulling mechanisms were adopted, and antecedent pushing-out was realized in the sloping insert of moving molds at the mold opening time by using wedge and sliding block. Fixed mould puller pins, stop drag-bars and pull-rod were used to open the mould sequentially. Such a mould structure was rational and safe in operation.

Key words: printer shell, antecedent pushing out, sloping insert
