Description

Mold device for shoe studs

technical field

The utility model relates to a mold device for shoe spikes, in particular to a mold device capable of producing shoe spikes with a tight fitting effect.

Background technique

Generally speaking, when manufacturing shoe studs, the connection part and the nail part must be manufactured in two steps, that is to say, the connection part must be prepared first, and then the nail part must be formed on the connection part. If the connecting part is made of metal, usually the nail part is formed at one time; if the connecting part is made of polymer material, the connecting part is formed on one machine, and then the connecting part is transferred to another machine for forming Nail department. However, to form nails with two colors on the connecting part made of metal, or to continuously form the connecting part and the nails on the same machine, it must be made in two consecutive moldings.

Next, please refer to FIG. 1 , the known spike 100 includes a connecting portion 101 and a spike portion 102 . The junction of the connecting part 101 and the nail part 102 of the shoe stud 100 is made by two-time molding, and its connecting strength is relatively poor, and the connecting part 101 of the shoe stud 100 cannot achieve a tight fit effect, and is used If there is a possibility that the studs fall off, it may further cause sports injuries to the user.

Therefore, it can be seen from the above that the above-mentioned shoe spikes manufactured by the known mold device for shoe spikes obviously have inconveniences and defects in actual use, and can be improved.

Contents of the invention

The main purpose of the present utility model is to provide a mold device for shoe spikes, which mainly passes through the second female mold and the third female mold in the perforation of the first female mold, and the second bearing part and the first bearing The parts are engaged with each other, so that the connection part of the stud can be engaged and formed on the second bearing part and the first bearing part. Thereby, the connection strength of the junction between the connecting portion and the spike portion of the conventional shoe spike is improved, and the spike will not fall off during use.

In order to achieve the above object, the utility model provides a mold device for shoe spikes, which includes a male mold base; a female mold base, which corresponds to the male mold base, and the female mold base includes: a first female mold, It is fixedly arranged, and a perforation is formed inside the first female mold; a second female mold is installed in the perforation of the first female mold, and the second female mold also forms a perforation; a third female mold, its A perforation is formed in the second female mold through the third female mold; and a thimble is arranged on the ejector seat and correspondingly pierced through the third female mold through the hole.

To sum up, the joint strength of the junction between the connecting part and the nail part of the shoe spike produced by the shoe spike mold device provided by the utility model is improved, and because there is a gap in the middle of the formed shoe spike connecting part , can be used as a buffer space and has a tight fit effect, so the studs will not fall off during use, and it is not easy to cause sports injuries to the user.

In order to further understand the technology, means and effects of the utility model to achieve the intended purpose, please refer to the following detailed description and accompanying drawings of the utility model, and believe that the purpose, features and characteristics of the utility model can be obtained from this For an in-depth and specific understanding, the attached drawings are only for reference and illustration, and are not intended to limit the present utility model.
