Layered feeding mechanism for PE (Polyethylene) material injection mold

Abstract

The invention relates to a layered feeding mechanism for a PE (Polyethylene) material injection mold, which comprises a mold frame, wherein a mold core is arranged in the mold frame, and a feeding runner and a mold cavity are arranged in the mold core. The layered feeding mechanism is characterized in that: 215 layered runner rings are arranged in the mold core, and a first layered runner ring is communicated with a feeding runner; and a last layered runner ring is connected with the end wall of the mold cavity into a whole body, and the layered runner rings are communicated by more than two runner openings. According to the scheme, after the pressure on the PE plastic raw material is divided by the 215 layered runner rings, the molecules of the PE plastic raw material is stably oriented, and the feeding is balanced; especially, the last layered runner ring is connected with the end wall of the mold cavity into a whole body, i.e., the excess stock of the last layered runner ring and the product are connected into a whole body after the product is molded to play a supporting role, accordingly, after the product is molded, the parameter is stable, the product does not contract and deform, the reliable quality of the product is ensured, and the service function is not affected.

Description

technical field [0001] The invention relates to a layered feeding mechanism of a PE material injection mold, which belongs to the field of injection molds. Background technique [0002] Using injection molds to produce plastic products, especially plastic products made of PE materials, due to the large shrinkage range and shrinkage value of PE materials, clear directionality, easy deformation and warping, especially unstable characteristics, the traditional injection molding process is adopted , that is, during injection molding, PE raw materials directly enter the mold cavity through the hot runner, which is easy to cause molecular orientation, which makes the product shrink and deform greatly, seriously affecting the function of the product in the actual use process. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a PE material injection mold with balanced feed, stable molecular orientat...
