[0039] With continued reference to the above structural description and the figures illustrated in FIGS. 4 to 9, the present invention further discloses a method for forming a shoe sole, and the specific implementation steps are as follows.

[0040] Step a: One first mold (20) and one second mold (40) are taken, wherein the second mold (40) is movable between one second mold open position spaced apart from the first mold (20) and one second mold closed position joined to the first mold (20).

[0041] Step b: As shown in FIG. 4, one first shoe last (50) and one second shoe last (60) are taken and can be mounted by one first sleeve member and one second sleeve member, respectively, and as shown in FIG. 5, the first shoe last (50) and the second shoe last (60) are each arranged in parallel with each other and detachably attached to the second mold (40).

[0042] Step c: Before the second mold (40) changes its position, the positions of the first mold body (21) and the second mold body (22) included in the first mold (20) are first changed using a linkage mechanism (30) to move the first mold body (21) and the second mold body (22) from a first mold closed position (shown in FIG. 3) to a first mold open position (shown in FIG. 5).

[0043] Step d: The position of the second mold (40) is changed so that the second mold (40) is moved from the second mold open position to the second mold closed position, and as shown in FIG. 6, the first shoe last (50) and the second shoe last (60) are moved synchronously together with the second mold (40) so that the first shoe last (50) is inserted into the first mold chamber (23) of the first mold body (21) and the second shoe last (60) is inserted into the second mold chamber (24) of the second mold body (22).

[0044] Step e: The interlocking mechanism (30) moves the first mold body (21) and the second mold body (22) simultaneously from the first mold open position (shown in FIG. 6 and FIG. 8) to the first mold closed position (shown in FIG. 7 and FIG. 9), so that a first shoe sole forming space (25) (shown in FIG. 7) is jointly defined by the inner wall surface of the first mold chamber (23) and the outer periphery of the first shoe last (50), and a second shoe sole forming space (26) (shown in FIG. 7) is jointly defined by the inner wall surface of the second mold chamber (24) and the outer periphery of the second shoe last (60).

[0045] Step f: One first shoe material raw material and one second shoe material raw material are injected into the first shoe sole forming space (25) and the second shoe sole forming space (26), respectively, so that the first shoe material raw material is integrally wrapped on the first sleeve member and the second shoe material raw material is integrally wrapped on the second sleeve member. In other words, the first shoe material raw material and the second shoe material raw material are combined with the first sleeve member and the second sleeve member, respectively, as an upper and a shoe sole, to form a molded shoe, and the first outsole color block and the second outsole color block are positioned at the bottom of the corresponding molded shoe. In another possible manner, the portion composed of the first shoe material raw material and the second shoe material raw material may be only the shoe sole of the corresponding molded shoe.

[0046] With respect to step e, the first mold body (21) further comprises a first blocking part (214) installed on the first mold member (211) and a second blocking part (215) installed on the second mold member (212), and when the first shoe last (50) is disposed through the cavity of the first mold (20) through the first mold opening (231) and the first mold body (21) is in the first mold closed position, as shown in FIG. 7, the first blocking part (214) and the second blocking part (215) are in contact with the outer periphery of the first shoe last (50), and the shapes of the adjacent cross-sections facing each other with respect to the outer periphery of the first shoe last (50) are complementary to each other, thereby thereby the first shoe The last (50) itself, the first blocking part (214), and the second blocking part (215) can jointly close the first mold opening (231), and the second mold body (22) further includes a third blocking part (224) installed on the fourth mold member (221) and a fourth blocking part (225) installed on the fifth mold member (222), and when the second shoe last (60) is disposed through the second mold opening (241) into the cavity of the second mold (40) and the second mold body (22) is in the first mold closing position, as shown in FIG. 7, the third blocking part (224) and the fourth blocking part (225) are in contact precisely on the outer periphery of the second shoe last (60), and the third blocking part (224) and the fourth The shape of the adjacent cross-sections facing each other with respect to the outer circumference of the second shoe last (60) is complementary to each other, thereby allowing the second mold opening (241) to be jointly closed by the second shoe last (60) itself, the third blocking part (224), and the fourth blocking part (225).In another possible embodiment, when the first shoe last (50) is positioned through the first mold opening (231) into the cavity of the first mold (20), the first shoe last (50) itself closes the first mold opening (231), and when the second shoe last (60) is positioned through the second mold opening (241) into the cavity of the second mold (40), the second shoe last (60) itself closes the second mold opening (241). In yet another possible embodiment, when the second mold (40) is in the second mold closing position, the first mold opening (231) and the second mold opening (241) are each closed by different parts of the second mold (40).

[0047] Accordingly, the present invention allows for the synchronous production of two sets of shoe soles, particularly the left and right feet of the same pair of shoes, through the above method, and by ensuring that the shoe soles are integrally wrapped on the upper or footgear, no complex manufacturing steps are required at all, thereby effectively improving production efficiency.

[0048] As illustrated in FIGS. 10 to 14, the main difference from the first embodiment of the present invention is that the second mold (40A) has two quantities and the shoe sole molding device is installed on the guide rods (91A) and further includes one mold exchange sheet (41) used to mount the second molds (40A). Accordingly, the different second molds (40A) can be replaced through the mold exchange sheet (41) to adapt to different molding requirements or to perform mold maintenance more quickly.

The mounting parts (413) are spaced apart and installed on opposite sides facing each other of the operating part (412), and each mounts a second mold (40A). When the operating part (412) operates, the operating part (412) moves the mounting parts (413) to exchange the positions of the second molds (40A) for use in molding operations or to perform mold replacement. Accordingly, the mold replacement time can be effectively shortened and the production efficiency of the molding operation can be improved.

[0050] Specifically, the fixed part (411) includes two sleeve sheets (4111), one first sheet body (4112), and one first rotation axis (4113), wherein one of the sleeve sheets (4111) is installed across two guide rods (91A), and the other of the sleeve sheets (4111) is installed across two guide rods (91A), and the sleeve sheets (4111) are arranged parallel to each other. As shown in FIGS. 12 and 14, the first sheet body (4112) is located between the sleeve sheets (4111) and is rotatably connected to the sleeve sheets (4111) through the first rotation axis (4113), so that the first sheet body (4112) can move between different positions according to mold exchange requirements, making it convenient to perform alignment work. Additionally, as illustrated in FIGS. 11 and 13, the operating unit (412) includes a second sheet body (4121), which is installed on the fixed unit (411) using a second rotation axis (4122) and rotates relative to the fixed unit (411) with the second rotation axis (4122) as a pivot point to exchange the second molds (40A). Here, the operation of the operating unit (412) can be performed manually or through an automated system. In this example, the operating unit (412) may include additional rotation axes so that the second sheet body (4121) can rotate or pivot in a multi-axis or multi-angle manner. The above description is merely for explaining various embodiments of the present invention and does not limit the scope of the present invention. That is, simple equivalent changes and modifications made in accordance with the claims and the specification of the present invention are all within the scope of the patent of the present invention.
