Description

Self-adaptive mode locking mechanism

Technical Field

The utility model relates to the field of related products of molds, in particular to a self-adaptive mold locking mechanism.

Background

When the die is used for molding products by using a hydraulic press, the upper die and the lower die are locked, certain pressure is maintained, and a hydraulic system needs to continuously work in the process of locking the die, so that additional energy consumption is generated. When the raw material is injected into the mold cavity under high pressure, a mold-supporting force is generated, so that the mold-locking unit of the injection molding machine must provide enough mold-locking force to prevent the mold from being supported. The lack of clamping force can cause flash or failure to form the product, and if the clamping force is too great, the waste of system resources is caused, and hydraulic system elements can work for a long time under high pressure, and the hydraulic system elements can be aged too early, so that the mechanical structure is worn too fast. Therefore, an adaptive mode locking mechanism is highly desirable.
