Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of injection molds, and particularly relates to a multi-cavity metal terminal embedded forming combined movable injection mold. BACKGROUND

[0002] In the manufacturing process of a traditional injection mold, for products that need to be embedded with metal terminals, a manual embedding method is usually adopted, i.e., the metal terminals are placed in the mold cavity one by one before injection molding, so as to realize the embedded forming of the plastic and the metal terminals. This method has certain applicability in early production due to limited equipment and process conditions, and the process flow is relatively simple and easy to operate and adjust.

[0003] However, with the increasing complexity of product structures and the increasing requirements of the manufacturing industry for product consistency, production efficiency and cost control, the manual embedding method gradually exposes a series of significant drawbacks. Especially in the scenario of using a multi-cavity mold structure to improve the single forming capacity, manually embedding the metal terminals one by one not only has low operation efficiency, but also is greatly affected by human factors. Since the metal terminals are small in size and precise in structure, problems such as terminal misplacement, omission or sliding into the mold gap are likely to occur during manual placement, which may cause injection defects, damage the mold, stop the equipment, and affect the overall production stability and yield.

[0004] In addition, after each injection cycle ends, the mold needs to wait for the manual placement of the next batch of terminals, which causes the equipment to be on standby for a long time, reduces the equipment utilization rate, lengthens the overall production rhythm, and seriously restricts the continuous production process of high efficiency and automation, which cannot meet the current modern manufacturing demand of large quantities and high efficiency.

[0005] Therefore, we propose a multi-cavity metal terminal embedded forming combined movable injection mold to solve the above technical problems. SUMMARY
