Good-quality mold for forming ventilating slippers

Abstract

The invention provides a good-quality mold for forming ventilating slippers. After mold compounding, the upper ends of vent hole forming columns abut against the lower sides of transverse air hole forming rods, the vent hole forming columns can elastically stretch out and draw back through lower springs to adapt to matching of the self height and the transverse air hole forming rods so that each vent hole forming column can closely abut against the lower portion of the corresponding transverse air hole forming rod, and then it is ensured that vent holes and transverse air holes in the bottoms of the slippers obtained after material injection and forming are communicated. Clamping head steps and clamping stop steps are matched so that the vent hole forming columns can be prevented from being separated out of through holes. The vent hole forming columns can be further matched with and closely attached to the transverse air hole forming rods through arc-shaped end grooves, and even slight position deviation exists, the vent hole forming columns can be incidentally combined with the outer circumference faces of the transverse air hole forming rods through the arc-shaped end grooves in a clamped manner, and abutting is more accurate. In addition, plug screws can be rotated to adjust the telescopic degree of the vent hole forming columns according to actual needs.

Description

technical field [0001] The invention relates to the field of shoe-making molds, in particular to a mold with good quality for forming ventilated and air-permeable slippers. Background technique [0002] Slippers with breathable function are becoming more and more popular. Such slippers are usually ventilated by connecting the air holes in the upper and lower directions with the horizontal air holes arranged in the horizontal direction. However, it is difficult to realize one-time injection molding of such slippers. In order to realize One-time injection molding of this type of slippers, Chinese invention patent CN201510229918.8 discloses a one-time molding breathable slippers mold, including an upper mold with an upper mold cavity, a lower mold with a lower mold cavity, and an upper mold and a lower mold. The shoe-last-shaped mold core in between, the rear side of the shoe-last-shaped mold core is hinged with the lower template, the rear side of the upper template is hinged ...

AI Technical Summary

Problems solved by technology

This invention can realize the one-time injection molding of the aforementioned slippers, but in the actual molding process, the finished slippers often have the situation that the air holes and the horizontal air holes are not connected due to the design error of the mold, which seriously affects the ventilation effect and quality of the finished slippers
