Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing, and in particular to a quick mold change positioning device for automotive injection molded parts. Background Technology

[0002] Automotive injection molded parts refer to special automotive components formed by injecting molten plastic raw materials into a special automotive injection mold using injection molding technology, followed by cooling and solidification. They are the core carrier of lightweight and integrated automotive design, accounting for 30%-40% of the total number of automotive parts, and widely replacing traditional metal parts to reduce the overall vehicle weight.

[0003] Injection molds mainly consist of two parts: a moving mold and a fixed mold. During injection molding, the moving mold and the fixed mold close together to form the mold's gating system and cavity. When the mold opens, the moving mold separates from the fixed mold along with the moving template to remove the molded plastic product. From a structural perspective, the mold includes various functional components such as guides, demolding parts, core pullers, and parting lines, all working together to ensure the stable operation of the molding process.

[0004] However, many parts of injection molds are high-frequency wear parts, especially small punches and dies with complex shapes and weak local structures, which require frequent repair or replacement during long-term use. Traditional repair and replacement processes have significant shortcomings: the entire lower mold part must first be removed from the equipment and disassembled. After repair or replacement, the lower mold must be manually positioned, which is inconvenient for aligning the upper and lower molds. Furthermore, the positioning pins of different molds are in different positions, often requiring manual alignment. This not only significantly increases the labor intensity of workers but also seriously affects the company's production rhythm, leading to a decrease in production efficiency and increasing labor costs, thus significantly impacting the company's production capacity and economic benefits.

[0005] Therefore, we propose a device for rapid alignment of upper and lower dies. Utility Model Content
