Description

Technical Field

[0001] The utility model relates to the technical field of rotational molding, and specifically relates to a rotational molding inner and outer mold forming device. Background Technique

[0002] Rotational molding is open-flame rotational molding, mainly for large equipment, so the mold size will be relatively large. The main problems encountered are that the inside cannot be directly heated, and due to the large size of the equipment, the lack of oxygen inside the mold during the rotation process will cause the open flame to go out. One-sided heating cannot evenly feed the material. Therefore, the current market for rotational molding uses a hollow outer mold form. Currently, rotational molding cannot heat the inside and outside of the barrel mold simultaneously, and cannot ensure the strength of the product after molding. At the same time, the distance between the rotating shafts of the existing rotational molding equipment is fixed and cannot be adjusted, and it cannot be applied to barrel molds of different sizes.

[0003] In response to the problems in the related art, no effective solution has been proposed yet. Summary of the Invention
