Abstract

This utility model provides a wide-mouth bottle preform injection mold, relating to the field of wide-mouth bottle injection mold technology. It includes an operating table and a processing mechanism disposed on the outer side of the end of the operating table. The processing mechanism includes a mold body and a rotating component disposed on the upper surface of the operating table. The rotating component is used to adjust the mold body at multiple angles. During the pressure holding stage, a motor is started to drive a series of components to rotate, ultimately causing the mold body to rotate. This causes the molten plastic to continuously redistribute within the cavity, accurately delivering excess melt to areas with lower pressure due to distance from the gate or mold structure, such as specific areas of the bottle body. This effectively prevents shrinkage marks and dents, significantly improving the product's appearance quality.
