る。 The structure of this invention in accordance with the above purpose is that the upper mold, in which different mold engraving spaces are formed at each work station, is brought into contact with the lower mold that is sequentially transferred to each work station. The first work station molds the first molding layer by injecting resin into the molding space from injection units that are integrally formed with each of the molds and filled with resins of different materials. At the second work station, a second molding layer is laminated and molded on the first molding layer,
The gist of this invention is to enable multilayer molding to be easily achieved in the same manner.

ある。 As mentioned above, according to this invention, the lower mold is installed on a rotary table and sequentially transferred to the molding work stations, while the upper mold is directly attached to the injection unit provided at each work station. By forming different mold engraving spaces, when each molding layer of a molded product is laminated and molded sequentially and stepwise at each work station, the lower mold has a common space at each work station. The structure of the mold is simple, as the same die-cutting space is formed, and different die-cutting spaces are formed in the upper die depending on the laminated structure of the molded product at each work station. Since there are no movable parts such as a lower die rotation mechanism, there are fewer failures.
This has the excellent effect of significantly improving operational reliability.

とによつて、従来必要とされていた上型板を省略
できるので、全体の構造が簡単になり、コスト面
においても、前記金型構造の簡略化と相俟つて、
大幅な経済化が図れるという利点がある。 Moreover, since the upper die has its own engraving space corresponding to the work station, it is extremely suitable for use in a molding machine in which the upper die is directly attached to the injection unit. By doing this, the upper mold plate that was conventionally required can be omitted, which simplifies the overall structure, and also reduces costs, along with the simplification of the mold structure.
It has the advantage of being significantly economical.
その上、成形作業は各作業ステーシヨンを通じ

作業ステーシヨンでの全体の作業に無駄がなく、
効率的な作業を行うことができるという効果もあ
る。 Moreover, since the molding work is carried out simultaneously and synchronously through each work station, there is no waste in the overall work at each work station.
It also has the effect of allowing you to work more efficiently.
