Positioning device for plastic extrusion molding mold

Abstract

The invention discloses a positioning device for a plastic extrusion molding mold. The positioning device is pin-shaped or key-shaped, and a hole is formed at the center of the positioning device. The positioning device is characterized in that an obvious color layer (2) with convenient recognition covers the outer surface of the positioning device. The positioning device disclosed by the invention has the advantages that different offsets are identified by using different colors and the values and directions of the offsets are matched, so that fast recognition can be achieved, the human resource is effectively saved and the production efficiency is also improved.

Description

technical field [0001] The invention relates to a positioning device for a plastic extrusion mold. Background technique [0002] Plastic extrusion molding dies are equipment used to produce plastic profiles. At present, in the extrusion molding of plastic extrusion molding molds, due to the high precision of the molding dimensions of the mold, frequent disassembly and high precision of reset, positioning devices such as positioning keys and positioning pins are generally used, and at the same time, they need to be used in weak acid and weak alkali environments. Better corrosion resistance and no rust requirements. Usually, the positioning device is made of metal materials such as stainless steel. Due to reasons such as the presence of chloride ions, the substrate and the positioning device are rusted, difficult to disassemble and install, and seriously affect the service life and appearance of the substrate and the positioning device. Depending on the specific use, positio...
