Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machine parts design, in particular to a two-platen machine steel belt structure. Background Art

[0002] Injection molding machine, also known as injection molding machine or injection machine, is the main equipment that uses plastic molding molds to make thermoplastic plastics or thermosetting plastics into plastic products of various shapes. During the operation of the injection molding machine, the movable template of the two plates of the injection molding machine frequently reciprocates. Therefore, a wear-resistant steel belt is laid on the frame slide rail within the sliding range of the movable template of the two-platen machine. Generally, small and medium-sized two-platen machines often adopt a single steel belt design. The two plates and their components of the two-platen machine reciprocate on the single steel belt under the push of the fast mold shifting cylinder. When encountering a large two-platen machine, the friction force on the steel belt is relatively large, and the steel belt arches and deforms under the action of friction. The width of a single steel belt is limited, and it is easy to break or even fall off, which makes it difficult to meet the actual use requirements. To this end, a steel belt structure for a two-platen machine is proposed. Utility Model Content
