Abstract

The application relates to the technical field of forming die equipment, and discloses a high-voltage cable accessory insulating part manufacturing forming die which comprises a mounting frame, a linear movement module capable of linear reciprocating movement is arranged in the mounting frame, a supporting seat for supporting the forming die when the die is closed is arranged on one side of the bottom of the mounting frame; a die closing forming mechanism is arranged above the supporting seat and is used for die closing processing when stress cones are subjected to injection molding processing; a flow control and densification mechanism is arranged on the upper portion of the mounting frame and is used for controlling and adjusting the raw material input and the internal pressure of the die according to different positions and processing stages of the stress cones. When the stress cones are subjected to die injection molding processing, the flow control and densification mechanism can not only realize the differential conveying and filling of the injection molding raw material according to the wall thickness gradient characteristics of the stress cones, but also can avoid defects such as air wrapping of the material flow, material shortage at the tip, root shrinkage and the like through the hierarchical gate and dynamic pressure and speed adjustment.
