Description

Shoemaking mold

This creation relates to a shoe-making mold, especially a mold for making rain boots.

Rain boots are a common type of footwear used to protect feet on rainy days or in workplaces with water (such as farming, fisheries, or sewer operations). Common rain boots are classified according to material, including rubber rain boots, EVA rain boots, PVC rain boots, etc.

As shown in Figure 1, when making rain boots, you need to first put the bushing 1S on the inner shoe mold 1P and cover the outer mold 2P (only the lower half is drawn, the upper half and the sole are omitted), and then Inject glue into the space between the inner and outer molds. After the glue solidifies to form rain boots, remove the rain boots and bushing 1S from the inner mold 1P. The function of the bushing 1S is to prevent the rubber of the rain boots from directly sticking to the inner mold 1 after injection.

As shown in Figure 1, the conventional rain boots manufacturing mold has a plurality of convex portions 11, such as nails, on the inner mold 1P corresponding to the shoe pockets of the rain boots, which are used to slightly tighten the bushing 1S after it is put on the inner mold 1P. Secure it tightly to prevent it from sliding easily after being put on. However, after the rubber injection is completed to form the rain boots, when the operator attempts to remove the rain boots and the bushing 1S, the convex portion 11 often hooks the bushing 1S, or even breaks it, or scratches the operator's hand. , making it inconvenient to remove the bushing 1S, causing trouble to the operators.

In order to improve the prior art, the creator of this creation designed a shoemaking mold to enhance industrial applicability.

The technical means used in this invention is to provide a shoemaking mold, which includes an inner mold and an outer mold. The outer mold has a mold cavity. The mold cavities of the inner mold and the outer mold have the shape of a rain shoe, and the inner mold The mold system is configured to be accommodated in the mold cavity of the outer mold and form a glue injection space between the outer mold and the outer mold. The inner mold is provided with a surrounding convex rib corresponding to the shoe collar of the rain boots.

In one embodiment of the shoemaking mold of the present invention, the protruding rib has a leading angle.

In one embodiment of the shoemaking mold of the present invention, the protruding rib has rounded corners.

In one embodiment of the shoe-making mold of the present invention, the convex rib has a concave arc surface, and the arc surface is connected to the inner mold corresponding to the boot portion of the rain boots.

In one embodiment of the shoemaking mold of the present invention, the inner mold and the outer mold are made of metal.

The inner mold of the shoemaking mold of this invention is provided with a surrounding convex rib corresponding to the shoe collar of the rain boots to replace the traditional convex portion. This makes it easier for workers to take off the rain boots and bushings from the inner mold, and avoids the problem in the prior art that the bushings are easily hooked when taking off the rain boots and bushings. In some variant embodiments, the protruding ribs may be provided with leading corners, rounded corners or concave arc surfaces, making it easier for operators to put on and take off the bushing.

The detailed description and technical content of this creation are described below along with the drawings. However, the attached drawings are only for reference and illustration to help understand this creation and are not intended to limit the scope of this creation.

What is disclosed in Figure 2 is an embodiment of the shoemaking mold of this invention. The shoemaking mold series 100 includes: an inner mold 1 and an outer mold 2 (only the lower half is shown, and the upper half and sole are omitted). The inner mold 1 and the outer mold 2 can be made of metal. The outer mold 2 has a mold cavity 2C. The inner mold 1 and the mold cavity 2C of the outer mold 2 have the shape of a rain shoe, and the inner mold 1 is configured to be accommodated in the mold cavity 2C of the outer mold 2. The inner mold 1 and the outer mold 2 can be fixed on an injection molding machine (not shown), and a mechanism that can control the opening and closing of the outer mold 2 is provided on the machine. When the outer mold 2 is closed and the inner mold 1 is enclosed inside, a glue injection space (not shown) is formed between the inner mold 1 and the outer mold 2, and the machine can pass through the glue injection hole on the outer mold 2 (not shown in the figure). Shown) Inject colloid into the glue injection space to form rain boots.

In this embodiment, the inner mold 1 is provided with a surrounding protruding rib 12 corresponding to the shoe collar of the rain boots. Before the outer mold 2 is closed, a bushing (not shown) can be placed on the inner mold 1 And the top of the bushing is covered with the rib 12; after the rain boots are formed, the operator can directly pull the end of the rain boots to slide the bushing, and it is not easy for the bushing to be caught or damaged by the ribs 12. Therefore, the arrangement of the protruding ribs 12 can make it more convenient to remove the rain boots and bushings. Further, as shown in Figure 3A, the rib 12 may have a leading corner or a rounded corner 12F, making it easier to put on and take off the bushing. Or as shown in Figure 3B, the convex rib 12 has a concave arc surface 12A. The arc surface 12A is connected to the inner mold 1 corresponding to the shoe collar of the rain boots, so that the operator can more easily put on and take off the bushing. For smoothness.

The above are only the best possible embodiments of this invention, and do not limit the patent scope of this invention. All equivalent structural changes made by using the description and drawings of this invention are deemed to be included in the scope of this invention. .
