Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a mold injection gate cutting mechanism. Background Art

[0002] Injection molding, also known as injection molding, is a highly efficient molding method that injects molten plastic material into a mold to form the desired product. Its advantages are fast production speed and automated operation. It is suitable for the production of products with a variety of colors, complex shapes, and precise dimensions. Injection molding can handle parts with complex shapes and is easy to update. It is suitable for large-scale production and processing fields that require products with complex shapes.

[0003] After searching, the Chinese patent with the announcement number: CN220593938U discloses a mold injection gate cutoff mechanism. The patent records that the motor will drive the moving block to move correspondingly through the threaded rod during the rotation process, so that the connecting rod will drive the second mold to move on the upper surface of the first mold, which plays a role in sealing the first mold. When the output of the electric telescopic rod is extended outward in one direction, it will drive the push-cut block to slide in the inner wall of the second mold accordingly, which plays a role in cutting off the injection port. The upper mold and the cutting knife need to move synchronously to seal the lower mold and cut off the injection port, which will cause part of the plastic melt in the lower mold to overflow during the movement of the upper mold, resulting in a technical solution of wasting the plastic melt;

[0004] The single use scope of the equipment in this solution means that it can only be used in specific production tasks or product manufacturing. If other types of production cannot be carried out when the equipment is idle, the resource utilization of the equipment will be affected, resulting in poor production efficiency. Unstable equipment operation will lead to unstable product quality. For example, inaccurate gate cutoff or inconsistent position may cause differences in the size, shape or appearance of the finished product. In order to solve this technical problem, the utility model proposes a mold injection gate cutoff mechanism. Summary of the invention
