The four first mold cavities 11 and the four second mold cavities 21 cooperate with each other for molding four or two pairs of soles, and the four third mold cavities 22 and the four fourth mold cavities 31 cooperate with each other for molding four or two pairs of soles. Two pairs of soles. The upper mold 1 and the middle mold 2 are connected by, for example, a sliding rod 12 and can move in a vertical direction, and the lower mold 3 remains stationary during the injection molding process. At least one corner of the upper mold 1, in this embodiment, all four corners has a first positioning member 13, and the lower mold 3 has a guide with a first positioning member 13 (in this embodiment, a circular cross section). However, other forms of positioning members are also conceivable, such as a guide post with a polygonal cross-section or a frustoconical positioning member) that cooperates with the second positioning member 32 ( FIG. 1B ), which is, for example, a first positioning member 13 ( guide post) with matching guide holes. During the closing process of the upper die 1, the middle die 2 and the lower die 3 and in the fully closed state, the guide post is inserted into the guide hole with matching shape, and finally completely accommodated in the guide hole, so as to realize the guiding effect during the closing process . According to requirements, the second positioning member can also be a guide column and the first positioning member can be a guide hole.

In addition to the positioning between the various parts of the mold 100 by the first positioning member 13 and the second positioning member 32 , side walls of the upper mold 1 , the side walls of the middle mold 2 and the side walls of the lower mold 3 are respectively formed with side walls. The wall positioning members 14, 23, 33, the side wall positioning members 14 of the upper mold, the side wall positioning members 23 of the middle mold and the side wall positioning members 33 of the lower mold can be inserted into each other in a form-fitting manner. In particular, the side wall positioning member 23 of the middle mold is formed as a protrusion, and the side wall positioning member 14 of the upper mold and the side wall positioning member 33 of the lower mold are formed as grooves. The upper part of the side wall positioning part 23 of the middle mold is matched with the side wall positioning part 14 of the upper mold, and the lower part of the side wall positioning part 23 of the middle mold is matched with the side wall positioning part 33 of the lower mold. In the closed state of the mold 100, the upper part of the side wall positioning part 23 of the middle mold is accommodated in the side wall positioning part 14 of the upper mold, and the lower part of the side wall positioning part 23 of the middle mold is accommodated in the side wall positioning part 33 of the lower mold; The upper part of the middle mold 2 except for the side wall positioning part 23 is located in the concave part 15 of the upper mold 1 , and the part of the lower part of the middle mold 2 except the side wall positioning part 23 is located in the depression part 34 of the lower mold 3 middle.

It can also be seen in FIGS. 1A-1B that both the upper mold 1 and the lower mold 3 are formed with injection fluid flow channels 4 extending in the horizontal direction, and a part of the injection fluid is injected from the first mold cavity 1 through the injection fluid flow channels 4 of the upper mold 1 . Another part of the injection fluid is injected into the cavity formed by the third cavity 22 and the fourth cavity 31 through the injection fluid flow channel 4 of the lower mold 3 .

The production process using the mould according to the present invention has the following steps:

- Install the mould 100, close and lock the upper mould 1, middle mould 2 and lower mould 3 of the mould 100;

- injecting injection fluid into the cavities of the mould 100;

- cooling the mould 100 until the injection fluid in the mould 100 has condensed to form;

- Open the mould 100 and take out the cold-formed sole.

2A-2B show perspective views from different angles of a mold according to a second embodiment of the present invention. 2A is looking at the mold from below, and FIG. 2B is looking at the mold from above. The main differences between the second embodiment and the first embodiment shown in FIGS. 1A-1B are:

Two opposite corners on the same diagonal line of the upper mold 1 have first positioning parts 13, the middle mold 2 has a third positioning part 24 at a position corresponding to the first positioning part 13, such as guide holes, and the lower mold 3 A second positioning member 32 is provided at a position corresponding to the first positioning member 13 and the third positioning member 24 . In this embodiment, the horizontal extension of the middle mold 2 corresponds to the upper mold 1 and the lower mold 3, so the first positioning member 13 formed as a guide post can be inserted into the third positioning member 24 and the second positioning member 32 which are matched in shape (guide hole). The third positioning member 24 of the lower mold 3 may also be omitted.

In addition, since the horizontal extension of the middle mold 2 corresponds to the upper mold 1 and the lower mold 3, the setting method of the side wall positioning members 14, 23, 33 is also different from the embodiment shown in FIGS. 1A-1B. Vertical concave-convex structures (replacing horizontal convexes and grooves) are formed on the sidewalls of the upper mold 1, the middle mold 2 and the lower mold 3, respectively, to assist positioning.

The lower mold 3 is formed with an injection fluid flow channel 4 extending in the horizontal direction; a through hole 25 is formed in the center of the middle mold 2, and an injection fluid flow channel 4 is formed on the side wall of the through hole substantially in the vertical direction. Correspondingly, the upper mold 1 and the lower mold 3 are formed with injection fluid flow channels 4 that penetrate in the substantially vertical direction, and are formed on the convex portion 16 that matches the shape of the through hole. , 35 side walls. The injection fluid flow channel 4 extending in the horizontal direction of the lower mold 3 is in direct fluid communication with the cavity formed by the third cavity 22 and the fourth cavity 31, and the injection fluid flow channel penetrating the middle mold in the vertical direction is in direct fluid communication with the cavity formed by the third cavity 22 and the fourth cavity 31. The cavity formed by the first mold cavity 1 and the second mold cavity 21 is in direct or indirect fluid communication for injection of injection molding fluid.

Thus, as in the embodiment shown in FIGS. 1A-1B , in the closed state of the mold 100 , the cavity formed by the first cavity 1 and the second cavity 21 and the cavity formed by the third cavity 22 and the fourth cavity The cavities formed by 31 are respectively closed into the shape of soles. After the injection fluid is injected into each cavity through the injection fluid flow channel 4 and cooled, four pairs of soles are molded in all cavities at one time.

The illustrated embodiments are only examples of, for example, that the device according to the invention or the method according to the invention can be implemented and these examples are not restrictive.
