Embodiment Construction

[0040] now refer to figure 1 . The mold 1 according to the invention is a mold for forming a motor vehicle part 2 made of plastic material MP, wherein said part 2 comprises at least one insert 3 . The insert 3 can be made of any material, in particular a metal material or a plastic material.

[0041] The mold 1 in particular allows the insert 3 to be partially overmolded. The overmolding is said to be partial when at least one surface of the insert is still visible after the overmolding: that is to say the surface is not covered by the plastic material MP during the overmolding.

[0042] The mold 1 comprises a female mold 1A and a male mold 1B defining at least an overmolding chamber 1C of the insert 3 and / or defining a cavity of the mold 1 .

[0043] In order to avoid movement of the insert 3 during molding of the plastic material MP, the mold 1 comprises at least one system 4 for positioning and maintaining the insert in the mould. The positioning and maintenance system ...

Abstract

The invention relates to a system (4) for positioning and retaining an insert (3) in a mold (1) for forming a motor vehicle part (2) made of plastic (MP). Said system includes at least one partially overmolded insert (3) and comprises at least one retaining member (5) for retaining the insert (3) in place in a given position. Said system is characterized in that the retaining member (5) includes a member (6) for inserting an insert, and the inserting member (6) comprises a means (7) for locking the insert onto the retaining member (5) by translating the insert (3) in the direction of the inserting member (6).

Description

technical field [0001] The invention relates to the technical field of the manufacture of plastic parts for motor vehicles, in particular to the field of overmoulding of inserts for motor vehicle parts. [0002] More specifically, the present invention relates to a system for positioning and maintaining an insert in a mold for overmolding of the insert, a mold including the system, and a method of manufacturing an overmolded part using the mold. Background technique [0003] In numerous industries, and in particular in the motor vehicle industry, hybrid components comprising a metal insert and a plastic part overmolded on the metal insert are manufactured and used. It is also known to use plastic inserts in overmoulding. [0004] In particular, the realization in the form of a hybrid component may be of large dimensions, such as a technical front window (French face avant technique) fixed to the structure of the motor vehicle in a transverse position and in front of the eng...
