Description

Composite core-pulling thread-removing mechanism
Technical Field
The utility model relates to a mould field, especially a compound thread demoulding mechanism of loosing core.
Background
Along with the diversified development of products, the products are bigger and bigger, correspondingly, the diameter of the thread is bigger and bigger, and the number of turns of the thread is also bigger and bigger. For demolding of plastic parts with internal threads, there are two main methods: firstly, the mold is provided with the insert, the product after injection molding is taken out together with the insert, and the thread is withdrawn outside the mold by utilizing a clamp and a rotating device, so that the mode has low production efficiency, high labor intensity of staff and is not beneficial to batch production; secondly, a motorized mold opening is adopted, when the mold is opened, the mold opening force or the pushing force of the injection machine is used as power (or the oil cylinder or the air cylinder is used as power), and the force is applied to the thread forming part through mechanical transmission parts such as a gear, a rack and the like so as to enable the thread forming part to rotate out of the product, so that the automatic demolding of the thread is realized. In actual operation, the threaded core and the movable template need to be linked together, the movable template moves downwards while the threaded core slowly rotates, but the speed difference often exists during movement, so that the phenomenon that internal threads are damaged possibly occurs, and the quality of a product is influenced; and the mold has complex structure, high cost and complex synchronous control. Especially for products with large thread diameter and multiple thread turns, the rack needs to be made very long, and then a long oil cylinder is added, so that the processing, pipe storage, transportation, injection molding machine and the like are very difficult. Therefore, a simple and quick thread stripping die mechanism is urgently needed.
