Description

Injection molded shoe midsole with grooves on bottom surface

technical field

The utility model relates to the technical field of shoe materials, in particular to an injection molding shoe midsole with grooves on the bottom surface.

Background technique

The midsole is an important part of many shoe soles, shaping and supporting the entire shoe. There is an existing injection molded shoe midsole, which is manufactured by mold injection molding technology. It is widely accepted by shoe factories and consumers because of its stable quality, low cost, and beautiful shape.

Some shoes, such as sandals, have a vamp or part of the vamp made of strips, which not only have the function of binding, but also can be woven into various styles, which has an aesthetic effect. For this kind of shoes with strips, at least one end of the strip must be fixed on the sole. Now it is common practice to open a groove on the periphery of the bottom surface of the midsole of the shoe, and the groove is at the side of the midsole of the shoe. An opening is formed, and the end of the strip passes through the opening and is placed in the groove, and then a layer of shoe material is covered on the bottom surface of the midsole of the shoe, and then stitched or glued or heat pressed or combined in a variety of ways to utilize the covering The end of the strip is affixed to the groove on the bottom surface of the midsole of the shoe.

In order to be applicable to shoes with strips, the existing injection-molded shoe midsole can be designed by mold, and directly injection-molded a groove with an opening on the peripheral part of the bottom surface of the shoe midsole for accommodating the end of the strip.

Since the number and position of the grooves on the bottom surface of injection-molded shoes depend entirely on the number and position of the finished shoe straps, and the formation of the grooves is completely completed by the mold structure, so when the number and position of the finished shoe straps change, the injection molding The number and position of the grooves on the bottom surface of the shoe midsole need to be changed accordingly, and the mold structure used to form the grooves needs to be changed accordingly, and changing the mold structure often takes a long time and costs relatively high. Therefore, the existing injection molded shoe midsole is difficult The number and position of grooves can be changed correspondingly quickly and at low cost.

However, the situation of changing the strips often occurs in the proofing and trial production stage, and it occurs frequently, even in the mass production stage, which will inevitably increase the manufacturing cost of the injection molded shoe midsole manufacturer and prolong the injection molding process. The delivery time of shoe midsoles adds a lot of troubles to manufacturers of injection molded shoe midsoles.

In addition, in the actual shoe-making process, the midsoles required by the same shoe factory or the midsoles required by different shoe factories within a period of time, or the midsoles of shoes with similar styles, are often in the main part of the midsole. It is the same, the only difference is the number or position of the grooves. But in order to make these small differences, it is necessary to remake the mold or change the existing mold. No matter which method is used, the mold is involved, which will undoubtedly increase a lot of manufacturing costs and prolong the manufacturing time.

The existing injection molded shoe midsole manufacturers have long been plagued by problems such as increased manufacturing costs and extended delivery times caused by changing the grooves on the bottom surface, and need to be resolved urgently.

Utility model content

The technical problem to be solved by the utility model is to provide an injection molded shoe midsole with grooves on the bottom surface, the grooves of which can be changed quickly and at low cost.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: an injection-molded shoe midsole with grooves on the bottom surface, including an injection-molded shoe mid-sole main body, and the periphery of the bottom surface of the shoe mid-sole main body is provided with protrusions side wall; a slot plate is attached to the bottom surface inside the side wall of the main body of the shoe midsole, and the peripheral portion of the slot plate has an opening; on the side wall, corresponding to the position of the opening of the slot plate, there is A notch, which together with the slot plate opening forms a groove for accommodating the end of the strip.

Further, the side wall forms a complete circle along the peripheral portion of the bottom surface of the midsole main body.

Further, the profile of the channel plate is adapted to the shape of the inner side of the side wall.

Further, the thickness of the slot plate is equivalent to the height of the side wall, and the width of the opening of the slot plate is equivalent to the width of the notch of the side wall.

Specifically, the grooved board is cardboard or fiberboard.

The midsole of injection molded shoes with grooves on the bottom of the utility model does not set the grooves on the main body of the midsole of injection molded shoes, but is formed by the gaps on the side wall and the openings on the groove plate, which does not affect its accommodation. The functionality of the strips makes the process of changing the groove only involve the opening of the groove plate and the gap in the side wall. It only needs to make a new groove plate after changing the opening and open the gap at the corresponding position on the side wall. Generally, making groove plates is faster and less expensive than making or modifying molds, so the grooves of the midsole of injection-molded shoes with grooves on the bottom surface of the utility model can be changed quickly and at low cost without increasing the manufacturing cost. There are also no extended lead times, solving a problem that has long plagued manufacturers of injection molded shoe midsoles.

The utility model provides an injection-molded shoe midsole with grooves on the bottom surface, which can quickly and cost-effectively change the grooves when the grooves are often changed. In addition, the frequent changes of shoes of the same shoe factory or similar shoes or shoes of the same period often only involve the groove, while the main part of the midsole of the shoe basically varies according to different shoe factories, different shoe models, different periods, etc. The elements can be divided into a small number of categories, so that the mold used for injection molding the main body of the shoe midsole can be solidified according to the divided categories to form a standardized mold, which can be commonly used to produce the shoe midsole or The shoe midsole of a certain shoe style or the shoe midsole of a certain period enables the standardized use of molds that account for a very high cost in the manufacture of injection molded shoe midsoles. Therefore, the injection molded shoe midsole with grooves on the bottom surface of the present invention can also promote The process of standardization of injection molded shoe midsole molds saves greater manufacturing costs for the manufacture of injection molded shoe midsoles.
