Steel plastic composite strip forming mould

Abstract

The invention discloses a steel plastic composite strip forming mould, which comprises an upper die body, a lower die body, an upper cover plate, a lower cover plate, strip cavities, an upper die body vacuuming chamber, a lower die body vacuuming chamber, an upper die body vacuuming port, a lower die body vacuuming port, an upper die body cooling water trough, a lower die body cooling water trough, an upper die body cooling water inlet and a lower die body cooling water inlet, wherein the strip cavities are formed on the upper die body and the lower die body; the upper die body vacuuming chamber and the lower die body vacuuming chamber are communicated with the strip cavities; the upper die body cooling water trough is arranged on the upper surface of the upper die body and comprises an upper die body water outlet which is communicated with the strip cavities of all feed ends; the lower die body cooling water trough is arranged on the lower surface of the lower die body and comprises a lower die body water outlet which is communicated with the strip cavities of all the feed ends; an upper die body vacuuming trough comprises transverse troughs which are arranged on the upper surface of the upper die body in the strip feed direction at intervals and are communicated with each other; each transverse trough stretches over all the strip cavities and is communicated with all the strip cavities; a lower die body vacuuming trough comprises transverse troughs which are arranged on the upper surface of the lower die body in the strip feed direction at intervals and are communicated with each other; and each transverse trough stretches over all the strip cavities and is communicated with all the strip cavities. According to the steel plastic composite strip forming mould, the wrinkle defect on the surface of a strip is eliminated, and the surface quality of the strip is improved.

Description

technical field [0001] The invention relates to a mold for shaping a steel-plastic composite strip. Background technique [0002] The steel-plastic composite strip shaping die is a mold used to shape the composite strip formed after the steel strip is compounded with high-temperature plastic in the extrusion composite mold. The performance of the steel-plastic composite strip calibrator plays a decisive role in the shape and surface quality of the strip. [0003] In order to overcome the defect that the plastic layer on the surface of the steel-plastic composite strip is uneven or even the shape is distorted, the existing steel-plastic composite strip shaping die is provided with a vacuuming groove and a vacuuming device connected with the strip cavity, which improves the strip Form quality. However, there are still wrinkles on the surface of the plastic layer in the strip produced by the existing steel-plastic composite strip sizing die, which makes the appearance quality...
