Injection-molding tool and method for producing an injection-molded part

#This application is the United States national phase of International Application No. PCT/EP2016/057040 filed Mar. 31, 2016, and claims priority to German Patent Application No. 10 2015 104 991.0 filed Mar. 31, 2015, the disclosures of which are hereby incorporated in their entirety by reference.

#The invention relates to an injection moulding tool for producing an injection moulded part, in particular consisting of plastic, having an injection mould which has a cavity corresponding to the negative of the shape of the injection moulded part to be produced. The invention further relates to a method for producing an injection moulded part using an injection moulding tool.

#Plastics are often chemically unreactive and difficult to wet since their long polymer chains have a low surface tension and possess no or only a few functional groups. Therefore, they bond badly and often have insufficient adhesion properties and have to be activated on the surface by means of a pretreatment.

#In the drawings,

#FIG. 1 shows an exemplary embodiment of the injection moulding tool according to the invention,

#FIG. 2 shows a further exemplary embodiment of the injection moulding tool according to the invention,

#FIG. 1 shows an exemplary embodiment of the injection moulding tool according to the invention in a perspective exploded illustration.

#The injection moulding tool 2 has a multi-part injection mould 4 which has a cavity 6 corresponding to the negative of the shape of the injection moulded part 8 to be produced. The injection mould 4 comprises a die half which in operation is fixed having a support 10 and an insert 12, as well as a movable die half 14 which for the injection moulding operation abuts tightly on the fixed die half (closed arrangement).

#The fixed die half in operation is attached to an injection unit via a sprue channel (not illustrated), so that molten plastic can be injected from the injection unit through the sprue channel into the cavity 6. The plastic solidifying in the cavity 6 then forms the injection moulded part 8.
