Abstract

A short knife-edge injection molding structure of a two-color mold, including a movable mold base and a movable mold core, characterized in that the movable mold core includes a main mold core and a secondary mold core, and a cylinder is arranged on the left and right sides of the movable mold base , the front side of the movable mold seat is provided with at least two air cylinders, and the left and right sides and the auxiliary mold cores on the front side are provided with vertical blade assemblies connected to the corresponding air cylinders. The vertical blade assemblies include vertical blades, blade seats, and T-shaped block, at least two vertical blades are arranged on each blade seat of the auxiliary mold core on the front side. Also stick together side by side, the upper part of the vertical blade is movably connected up and down at the exit of the soft rubber runner, the lower part of the vertical blade is fixed on the blade seat, and the upper surface of the wide part of the T-shaped block is a slope. The mold size of the structure is small, so that the size of the injection molding machine can be reduced and the production cost can be saved.

Description

technical field [0001] The invention relates to the technical field of mold injection molding, in particular to a two-color mold short-edge injection molding structure. Background technique [0002] An existing automobile tailgate fairing product, the structure of which is as follows figure 1 As shown, the main body of the product is made of hard glue, and only the edges of the left, right and front sides of the main body are injection-molded with elongated soft glue. Due to the large size of the main body of the product, if a common rotary two-color mold is used, the mold must be designed to be very large, and the required injection molding machine is also very large, resulting in very high production costs. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a two-color mold short-edge injection molding structure with a smaller mold size, thereby reducing the size of the injection molding machine and saving product...
