AI Technical Summary

Technical Problem

When traditional automotive injection molding devices heat plastic particles, the large-particle plastic particles are difficult to completely melt, resulting in a reduction in the pass rate of injection molded parts.

Method used

An injection molding device for automobile injection molding parts is designed, and a multi-functional stirring mechanism is built into the heating cylinder, including a stirring rack and screen mesh surface. Through the rotation of the mixing rack and the impact of the installation tank, large-grained plastic particles are crushed, and unmelted plastic particles are salvaged through the screen mesh surface to ensure material uniformity and efficient heating.

Benefits of technology

Through stirring and screening, the melting rate of plastic particles and the pass rate of injection molded parts are improved, the processing efficiency of heating plates is enhanced, and the quality stability of injection molded parts is ensured.

Abstract

The utility model discloses an injection molding device of an automobile injection molded part, which comprises a heating cylinder, the inner wall of the bottom of the heating cylinder is fixedly connected with a heating plate, the outer wall of the top of the heating cylinder is fixedly provided with a material conveying pipe communicated with the inside, and the bottom of the outer wall of one side of the heating cylinder is fixedly provided with a screw extruder. A plurality of groups of multifunctional stirring mechanisms are arranged inside the heating cylinder, each multifunctional stirring mechanism comprises a stirring frame and a material screening net surface, the outer wall of each stirring frame is provided with a mounting groove, the two sides of each mounting groove are communicated, and the outer wall of each material screening net surface is fixedly connected with the inner wall of the corresponding mounting groove. According to the screw extruder, plastic particles with large sizes can be cracked and crushed and are easier to melt, and after the plastic particles in the heating cylinder begin to be heated and melted, the large plastic particles which are difficult to melt can be fished by the screening net surface through the rotation of the stirring frame, so that the texture of materials extruded by the screw extruder can be uniform.
