Abstract

The invention discloses an automatic demolding injection mold. The automatic demolding injection mold comprises a fixed mold module and a movable mold module; and the movable mold module is provided with a pushing mechanism, a lower template, a rotating mechanism and a base plate in sequence from top to bottom. The automatic demolding injection mold further comprises lower mold cores correspondingto upper molds in number; the lower template and the base plate are fixedly connected through multiple support columns; each lower mold core penetrates through the lower template; the pushing mechanism is arranged on the upper end surface of the lower template; the pushing mechanism comprises a push plate and a first spring connected between the push plate and the lower template; the rotating mechanism comprises a motor, a driving gear connected to an output end of the motor, a first driven gear connected with the driving gar through a chain, and multiple second driven gears engaged with thefirst driven gear; and each second driven gear is fixedly connected to the lower ends of the lower mold cores. The automatic demolding injection mold can protect internal threads of products, realizesthorough separation of the lower mold cores from the products, and achieves high production efficiency.

Description

technical field [0001] The invention relates to the field of molds, in particular to an automatic demoulding injection mold. Background technique [0002] Commonly used feeding bottles are mostly made of plastic, including nipples, threaded caps, handles, and bottle bodies. The threaded caps have internal threads and are mostly made by hot runner injection molding. [0003] The utility model with the patent number of 2012203916694 discloses an automatic demoulding mechanism for the inner thread of the injection mold. Using this mechanism, the rotating core of the product to be produced will slowly rise from the thread, and at the same time, the stripping plate will slowly move upward under the action of the spring and keep In close contact with the product, after the product is completely out of the thread, the stripping plate continues to push up a certain distance under the action of the spring, thereby ejecting the entire product. The above process completes the entire pr...
