8. Mould structure according to any of claims 1-7, characterized in that the rear mould (3) is provided with a cavity and that the flow field plate (2) is provided with a flow guiding surface (21) for the flow of material into the cavity.
9. Mould structure according to claim 8, characterised in that it further comprises a front mould (1), said front mould (1) being provided with a guide sleeve (9), said rear mould (3) being provided with a guide post (10) cooperating with said guide sleeve (9).
10. A method for processing an injection molded product, which is applied to the mold structure according to any one of claims 1 to 9, comprising:
after the rear die (3) and the front die (1) are closed, injection molding is started;
opening the front mold (1) and the rear mold (3);
pushing the runner plate (2) through the first ejector plate die set (5) to separate the material handle (01) from the product (02);
the first ejector plate die set (5) drives the second ejector plate die set (6) to synchronously move so as to eject the product (02) from the rear die (3);
and resetting the first ejector plate die set (5) and the second ejector plate die set (6).
