Abstract

The invention discloses a dovetail telescopic core. The dovetail telescopic core comprises a central rod and further comprises a cylinder with a cavity, wherein the cylinder is composed of a pluralityof wide telescopic blocks and narrow telescopic blocks arranged at intervals. The central rod is arranged in the cavity and movably connected with the wide telescopic blocks and the narrow telescopicblocks through dovetail grooves. The dovetail telescopic core is used for solving the problems that due to traditional mold structure design in practical production, production efficiency is low, themolding period is long, product size precision is low, structures are complex and cost is high, thereby simplifying mold structures, lowering cost and improving productivity.

Description

technical field [0001] The invention relates to injection mold spare parts, in particular to a dovetail telescopic core. Background technique [0002] Parts in industries such as medical, packaging, water pipes, water conservancy and electronic connectors often have internal undercuts, internal sealing ring grooves and internal threads. These product structures bring difficulties in demoulding during injection molding production. Injection molds usually use traditional oil cylinder racks to drive gears to rotate and dethread or use reciprocating rods to drive gears to dethread and other mold structure designs. However, these traditional structures have complex designs, high mold manufacturing costs, long injection molding cycles, low production efficiency and product size. Shortcomings such as low precision. Contents of the invention [0003] The purpose of the present invention is to create and provide a kind of injection mold parts with the function of stretching and sh...
