AI Technical Summary
Technical Problem
Existing automatic nut release molds require an external power source for demolding during injection molding, resulting in low production efficiency.
Method used
An automatic demolding mold including an injection molding demolding mechanism and a snap-fit mechanism was designed. The automatic demolding of the nut is achieved through the cooperation of the inclined guide post and the spring, and the mold transfer is facilitated by the snap-fit structure of the L-shaped strip and the spring.
Benefits of technology
This enables rapid demolding of nuts and simple mold transfer, improving injection molding efficiency and production efficiency.

Abstract
The utility model discloses a fixed nut's automatic shedding mould relates to nut injection molding field, include: back template, injection demoulding mechanism, this mechanism sets up in back template top. The utility model discloses a injection demoulding mechanism's effect can injection molding fixed nut, and can the nut of injection molding that finishes is handled fast demolding, in the process of pushing front template to back template, front template drives lower pressing plate to remove, and lower pressing plate drives two inclined guide pillars to remove, and makes two side templates move on the track oppositely, after sticking side template, extruding plate is pressed in the outside, and adaptive pressure plate is pressed in the top, and through the injection port on front template adds raw materials, after nut forming, the front template moves from back template injection cavity board one side outward, under the action of first spring, applies reverse thrust to injection cavity board, and the nut that injection molding that finishes is demoulded, has the effect that the nut that injection molding that finishes is handled fast demolding, improves the injection efficiency of fixed nut.
