Description

Technical Field

[0001] This utility model belongs to the field of mold insert assembly technology, and in particular relates to an insert floating assembly mechanism. Background Technology

[0002] Metal insert injection molding is a method in which a metal insert is pre-fixed in an appropriate position in a mold, and then plastic is injected to form the insert. After the mold is opened, the insert is encased in the cooled and solidified plastic and obtained a product with inserts such as threaded rings and electrodes.

[0003] Currently, metal insert injection molding typically employs manual placement of pre-embedded inserts and a small number of automated placement methods. This approach results in low production efficiency and increased production costs. Furthermore, the injection molding and insert placement workstations are characterized by high temperatures, strong plastic odors, frequent movements, and high work intensity, making manual work at this station undesirable for operators. Manual work also cannot guarantee the accuracy of insert placement, affecting the consistency of the finished injection-molded products and leading to defective items and production waste.
