Background

The vertical injection molding machine is integrally and vertically arranged, the glue injection system is arranged at the topmost end, and the hydraulic motor driving the conveying screw to rotate occupies the position above the screw vertically, so that the discharging hopper containing the molten plastic can only be arranged above the conveying screw obliquely, and then the inclined material guide pipe is connected with the bottom end of the discharging hopper to guide the molten plastic into the conveying screw. Because the guide pipe is obliquely arranged instead of being vertically arranged, in the actual production process, the viscosity of the molten plastic is higher, the guide pipe is often blocked, and the quality of the product in normal production is greatly influenced.

The method for solving the problem of the blockage of the material guide pipe in the existing injection molding processing industry generally comprises the following steps: (1) the inclination angle of the material guide pipe is reduced, so that the material guide pipe is as close to vertical as possible. The method is limited by space and can only relieve the situation to a certain extent, and the effect is very little. (2) The blowing device is additionally arranged in the inclined material guide pipe, the molten plastic is prevented from being blocked under the action of the air flow, but the air flow can take away heat, so that the temperature of the molten plastic is reduced, and the injection molding quality of the product is reduced.
