Abstract

The invention relates to an insert positioning device for an injection mold and the injection mold, the insert positioning device is used for installing and fixing an insert in the injection mold, the injection mold comprises a lower mold base and a lower mold core, and the insert positioning device comprises the insert, a spiral fixing rod and a driving mechanism. The spiral fixing rod is rotatably installed in the insert and is kept fixed in the axial direction, the driving mechanism drives the spiral fixing rod to rotate, a connecting section is arranged at the front end of the spiral fixing rod, a fastening thread is arranged on the connecting section, a part of the fastening thread is cut off to form an avoiding notch, a connecting round hole is formed in the insert, and the connecting round hole is communicated with the spiral fixing rod. A convex rib is arranged on the hole wall of the connecting round hole, the connecting round hole of the insert is arranged on the connecting section of the spiral fixing rod in a sleeving mode, and when the spiral fixing rod rotates, the convex rib can be inserted into the fastening thread or located in the avoiding notch; the insert is installed in the lower die base or the lower die core, and the insert installed on the spiral fixing rod is located in the lower die core.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to an insert positioning device for an injection mold and an injection mold. Background technique [0002] In the production of automotive wiring harness products, it is often necessary to produce injection molded products with inserts. In the injection molding process of ordinary injection molded products with inserts, the inserts need to be placed in the specified position in the mold after the mold is opened, and then the mold is closed and injected. , Open the mold and take out the injection molded parts. In existing injection molds, when injecting products with inserts, due to the impact of high-pressure and high-speed molten plastic in the mold cavity, the position of the inserts will shift, which may cause product defects in the slightest, or cause product scrapping in severe cases. Contents of the invention [0003] In view of the above-mentioned shortcomings of...
