Description

Mould for moulding shoe shell, decorative film and manufacturing method thereof

technical field

The present invention relates to a manufacturing tool and a manufacturing method for a shoe shell, and in particular, to a mold for molding a shoe shell, a decorative film and a manufacturing method thereof.

Background technique

In order to increase the structural strength of some sports shoes (such as ice skates), the manufacturing method is to add a hard and shape-fixable material layer to the material, such as molding a hard plastic shoe body by plastic injection to achieve high strength. , Comfort and solidity.

In addition, when there is a pattern and color requirement on the surface of the plastic shoe body, in-mold decoration technology (In ModeDecoration, IMD) can be applied, and the film with pattern and color is placed inside the mold and then injection molding is performed to make the pattern and color. The film is combined with the surface layer of the plastic to form a decorative effect.

However, the above-mentioned injection molding surface decoration technology (IMD) needs to be subjected to a great injection pressure during the molding process, so that the decorative film inside the mold cannot be accurately positioned at the predetermined position, causing the patterns and patterns on the surface of the finished product to be offset or wrinkled. and other defects, which reduces the manufacturing yield of the plastic shoe body.

Moreover, when the finished product has a large area or its appearance is a complex curved surface, it is only pressed by the parting line between the male and female molds or by setting a convex mold core, and the decorative film may be pressed before the mold is closed, that is, Displacement due to gravity or stress recovery, resulting in unexpected pattern positions or wrinkles on the finished product.

In view of this, the inventor of the present invention has devoted himself to the above-mentioned prior art, and cooperated with the application of theories to try his best to solve the above-mentioned problems, which is the goal of the present inventor's development.

SUMMARY OF THE INVENTION

The invention provides a mold for molding shoe shells, a decorative film and a manufacturing method thereof. The decorative film is provided with a plurality of positioning holes, and the foot-shaped mold core is provided with a plurality of positioning pins. During injection molding, the decorative film can be selected according to requirements. The plurality of positioning holes on the decorative film are correspondingly inserted with the plurality of positioning pins, which is also different from the conventional simple pressing. Since the plurality of positioning holes on the decorative film are substantially through holes, once the positioning holes are correspondingly inserted with the positioning pins The decorative film is not easily displaced by the injection pressure of the mold, so that the decorative film can be stably positioned on the foot-shaped mold core, so that the injection molded shoe shell has a pattern, the pattern is flat and stable, and the wrinkle is avoided and the yield of the finished product is improved. The advantages.

In an embodiment of the present invention, the present invention provides a method for manufacturing a molded shoe shell, the steps of which include: a) providing a male mold, the male mold has a foot-shaped mold core, and the surface of the foot-shaped mold core has a plurality of positioning pins; b) providing a decorative film, the decorative film comprises a plastic film and a pattern printing layer, the plastic film has an upper surface and an outer periphery, the plastic film is provided with a plurality of positioning holes arranged along the outer periphery, The pattern printing layer is draped on the upper surface; c) firstly dispose the pattern printing layer toward the foot-shaped mold core, and then insert the positioning holes and the positioning pins on the decoration film correspondingly, so as to make the decoration The film is positioned on the foot-shaped mold core; d) a female mold is provided, and the female mold is provided with a mold cavity, and the female mold and the male mold are mutually closed, so that the foot-shaped mold core is accommodated inside the mold cavity; e ) inject molten plastic into the mold cavity, so that the plastic is filled between the foot-shaped mold core and the decorative film; f) perform a cooling operation on the plastic, so that the plastic is cooled and formed into a surface combined with the decorative film. a plastic shoe shell, the pattern printing layer is sandwiched between the plastic film and the plastic shoe shell; and g) demoulding the female mold and the male mold.

In an embodiment of the present invention, the present invention provides a mold for molding shoe shells, which is used for a decorative film, the decorative film has a plurality of positioning holes, and the mold includes: a female mold with a mold cavity; and a male mold. The mold is closed with the female mold, the male mold has a foot-shaped mold core accommodated in the mold cavity, the surface of the foot-shaped mold core has a plurality of positioning pins, the positioning holes on the decorative film and the The positioning pins are inserted correspondingly, so that the decorative film is positioned on the foot-shaped mold core.

In an embodiment of the present invention, the present invention provides a decorative film for molding a shoe shell, comprising: a plastic film having an upper surface and an outer periphery, the plastic film is provided with a plurality of positioning positions along the outer periphery holes; and a pattern printing layer covering the upper surface.

Based on the above, in the process that the plastic flows between the foot-shaped mold core and the decorative film, the decorative film will be subjected to a great injection pressure, but the decorative film of the present invention is provided with a plurality of positioning holes, and the foot-shaped mold core has a plurality of positioning pins, so that the The plurality of positioning holes on the decorative film are correspondingly inserted into the plurality of positioning holes.
