Injection molding and assembly apparatus and method of molding and assembling a plurality of two different molded parts

An injection molding apparatus may include a first mold plate and a second mold plate. The second mold plate may be movable outside an injection molding station defined by these mold plates. The second mold plate may carry parts of type A and parts of type B molded at the same time within the injection molding station. A transferring mechanism may carry the second mold plate to removing and assembling stations where molded parts A are first removed from the second mold plate and next parts A are positioned relative molded parts B, where the molded parts B and A are finally assembled. Simultaneously other parts A and B may be molded at the injection molding station using an additional and identical second mold plate. Depending on the application, molded parts A and B may be made of the same or different materials.

An injection molding system including an injection molding apparatus and a conveying apparatus for conveying a mold with respect to the injection molding machine, the conveying apparatus including a support member for supporting a bottom of the mold, and a guide member located on a side of the mold for guiding the mold conveyed by the conveying apparatus, wherein the improvement to the conveying apparatus includes an adjustment member for adjusting a position of the guide member in a direction intersecting a direction of conveyance of the mold by the conveying apparatus independently from a position of the supporting member.

Mold movement control mechanism and mold having the same

The present invention provides a mold movement control mechanism which is suitable for being assembled in mold to drive the plates of the mold to move. The mold movement control mechanism has a rotatable engaging member and two moving members. In one predetermined travel section, the engaging member is kept unable to rotate. The moving members are then engaged and moved together by the engaging member. After the moving members and the engaging member are moved across the predetermined travel section, the engaging member become rotatable, and the moving members are moved independently. Thus, the mold movement control mechanism can control the positions and travel paths of the moving members without spring. Manufacturing tolerance and maintenance cost could be both lowered.

Method, mold insert and injection mold for producing a plastics molding

Method for producing a plastic molded part (1), wherein, in the method, a mold insert (3) with a diffractive surface relief (32) is provided, the mold insert (3) is inserted into one mold half of an injection mold (5) which, together with at least one further mold half, forms a cavity for producing the plastic molded part (1), wherein the mold insert (3) is inserted into the injection mold (5) such that the diffractive surface relief (32) forms a partial area of the surface of the cavity formed by the mold half (5), and the plastic molded part (1) is molded by injection molding by means of the injection mold (5). The invention furthermore relates to a mold insert as well as an injection mold for such a method, as well as a plastic molded part produced in this way.
