Description

Technical Field

[0001] The utility model relates to a forming device, in particular to a lasting forming device. Background Art

[0002] The midsole is located between the outsole and the upper, and is mainly used to provide shock absorption, propulsion feedback, and stable support. The midsole formed by combining different thicknesses and different material properties can produce shoes with different functional orientations and different wearing experiences. The injection molding process is one of the main technologies currently used to make midsoles. The midsoles produced by it have the advantages of light weight, rich colors, wear resistance, corrosion resistance and low cost, and are therefore widely used in modern life.

[0003] See also Figure 1 and Figure 2 As shown, the aforementioned injection molding process is mainly processed by a draw molding device 1, and the draw molding device 1 includes a first mold 11, a second mold 12 arranged opposite to the first mold 11, at least one injection channel 13 formed in the first mold 11 and the second mold 12, an upper body 14 for a shoe upper A1 to be mounted, a receiving seat 15 installed in the first mold 11 and for a shoe outsole A2 to be placed, and a molding groove 16 located between the upper body 14 and the receiving seat 15, and the draw molding device 1 cooperates with an injection molding device 2 to perform injection molding operations of the material M1.

[0004] Continuing with the above, when the upper forming device 1 is used, firstly, a shoe upper A1 is put on the shoe upper body 14 so that the shoe upper A1 fits the shoe upper body 14, and at the same time, a shoe outsole A2 is placed in the accommodating seat 15, and the first mold 11 is moved downward to close the second mold 12, and then the injection molding device 2 directly injects the material M1 into the first mold 11 and the second mold 12 at a certain temperature and pressure. Figure 1 The dotted line simply shows the injection of the material M1, so that the material M1 enters the molding groove 16 through the injection channel 13. Since the molding groove 16 is located between the upper body 14 and the accommodating seat 15, the midsole A3 formed by the material M1 after cooling and solidification can firmly bond the upper A1 and the outsole A2 together to complete the preliminary molding of a finished shoe (not shown in the figure). Then, it is only necessary to open the first mold 11 and the second mold 12, remove the finished shoe from the upper body 14 and carry out subsequent processing.

[0005] However, after actual use, it was found that because the first mold 11 and the second mold 12 are designed to open and close up and down, the operating space between the first mold 11 and the second mold 12 is limited, which not only makes it difficult to quickly place the shoe outsole A2 in the accommodating seat 15, but also during the displacement of the first mold 11, the shoe outsole A2 may be affected by gravity and shift or fall. Not only does it cause the shoe outsole A2 to be skewed and uneven after molding, it also affects the injection molding effect of the shoe midsole A3, thereby increasing the defective rate of the finished product and causing waste of the material M1, resulting in an increase in production costs. Moreover, the finished shoe after molding is difficult to quickly remove from the shoe upper body 14, which not only leads to poor operating efficiency, but also may cause damage to the finished shoe during the removal process. This really needs to be improved. Utility Model Content

[0006] Therefore, the purpose of the utility model is to provide a shoe upper forming device, which can effectively increase the operating space to quickly position the shoe outsole and take out the formed shoes, thereby improving the operating convenience, increasing the operating efficiency and the finished product yield, and reducing the production cost.

[0007] Therefore, the upper forming device of the utility model is used in conjunction with a shoe upper, a shoe outsole and an injection molding device, so that the injection molding device performs injection molding of materials to combine the shoe upper and the shoe outsole to form a molded shoe. The upper forming device includes a mold group with an internal accommodating space, a shoe upper body installed in the accommodating space, a molding groove formed in the accommodating space and located at a corresponding position of the shoe upper body, and at least one injection molding channel formed in the mold group and connected to the molding groove, wherein the mold group has a first mold and a second mold that are respectively arranged correspondingly, and a A positioning seat is pivotally mounted on the second mold, and a working area is formed on the positioning seat and is arranged toward the molding groove. When the first mold and the second mold are in an open state, the molding groove is located between the upper body and the positioning seat. Therefore, the positioning seat is flipped outward to increase the operating space, which is more conducive to quickly placing and positioning the outsole in the working area, and effectively avoiding the outsole from being skewed, displaced or falling off due to mold closing, and helping to quickly take the finished shoe out of the mold group, which effectively improves the working efficiency, enhances the convenience of operation, increases the yield of finished products, and reduces the production cost.

[0045] The above and other technical contents, features and effects of the present invention will be clearly understood in the following detailed description of the preferred embodiments with reference to the drawings.

[0046] See also Figure 3 , Figure 4 and Figure 5 As shown in the figure, a preferred embodiment of the upper forming device 3 of the utility model is used in combination with a shoe upper B1 and a shoe outsole B2, and is also used in combination with an injection molding device 4 to perform an injection molding operation of a material M2, so that the shoe upper B1 and the shoe outsole B2 are combined with a shoe midsole B3 formed by injecting the material M2 to produce a finished shoe (not shown in the figure). The upper forming device 3 includes a mold set 31, a receiving space 32 formed in the mold set 31, and a pivotally mounted on the mold set 3. 1 and located in the accommodating space 32, a molding groove 34 formed in the mold set 31 and located at a corresponding position of the shoe upper body 33, and at least one injection channel 35 formed between the injection molding device 4 and the molding groove 34, so that the material M2 injected by the injection molding device 4 enters the molding groove 34 through the injection channel 35, and the shoe upper body 33 is used for the shoe upper B1 to be set and positioned. After the material M2 is injected, the molded shoe can be formed in the mold set 31. In addition, the injection molding device 4 is Figure 4 It is shown in a simple diagram, and the state of the injection molding device 4 should not be limited to this.

[0047] See also Figure 3 and Figure 4As shown, the mold set 31 has a first mold 311, a second mold 312 arranged opposite to the first mold 311, and a positioning seat 313 pivoted on the second mold 312, and a working area 314 facing the molding groove 34 is formed on the positioning seat 313, and the working area 314 is used to set and position the outsole B2. In addition, this embodiment takes the first mold 311 and the second mold 312 arranged opposite to each other in an upper and lower direction as an example, and the upper body 33 has an actuating member 331 pivoted on the second mold 312, and a shoe last 332 fixed on the actuating member 331 and capable of being mounted on the upper B1. When the first mold 311 and the second mold 312 are separated from each other and in an open state, the shoe last 332 is located between the actuating member 331 and the molding groove 34, and the molding groove 34 is located between the shoe last 332 and the working area 314.

[0048] See also Figure 3 , Figure 4 and Figure 5 As shown, when the upper forming device 3 is used, the upper B1 is firstly sleeved on the shoe last 332 of the upper body 33. At this time, the actuating member 331 of the upper body 33 is pivoted on the second mold 312, so that the upper body 33 can be rotated, that is, the actuating member 331 is rotated outward, thereby driving the shoe last 332 to be in an upright state, that is, Figure 3 As shown, the upper B1 can be quickly put on the shoe last 332, and then the upper B1 is tightened to make the upper B1 fit tightly against the shoe last 332. Then, the upper body 33 only needs to be pivoted inward, that is, the actuator 331 is rotated inward to reset, so that the shoe last 332 and the upper B1 are positioned in the second mold 312, thereby completing the positioning operation of the upper B1.

[0049] Continuing with the above, the positioning seat 313 is pivoted on the second mold 312 so that the positioning seat 313 can also rotate, that is, the positioning seat 313 is rotated outward to drive the working area 314 to expand toward the first mold 311, thereby increasing the space during operation and quickly placing the shoe outsole B2 in the working area 314. Then, the positioning seat 313 only needs to be rotated inward so that the working area 314 together with the shoe outsole B2 is flipped inward toward the molding groove 34. In this way, the shoe outsole B2 can be stably fixed in the desired position. Finally, the first mold 311 and the second mold 312 are tightly covered with each other and are in a closed state. Then, the molten material M2 is injected into the mold set 31 at a set temperature and pressure through the injection molding device 4. In this embodiment, Figure 5In the figure, only the dotted line is used to simply illustrate the injection of the material M2, and the shape of the material M2 is not limited. Here, the molten shape is used as an example for explanation. Then, the material M2 enters the molding groove 34 through the injection channel 35 and evenly fills the molding groove 34. After cooling, the shoe midsole B3 is formed, and the shoe midsole B3 bonds the upper B1 and the outsole B2 to form the finished shoe. Finally, only the first mold 311 and the second mold 312 need to be separated from each other and opened, and the positioning seat 313 and the upper body 33 are turned outward respectively, so that the finished shoe can be quickly taken out for subsequent processing of the finished shoe. Therefore, the operating space is greatly increased through the rotation of the positioning seat 313, making the positioning operation of the shoe outsole B2 faster and more convenient, further enhancing the operational convenience and improving the operating efficiency. At the same time, the shoe outsole B2 can be effectively prevented from being skewed or shifted due to the movement of the first mold 311 and the second mold 312, so that the shoe outsole B2 is flat after molding, further enhancing the wearing comfort and greatly improving the finished product yield. At the same time, it can also avoid wasting the material M2. In addition, the finished shoe will not be damaged during the process of taking out the finished shoe, thereby effectively reducing the production cost.

[0050] To summarize the above, the upper forming device of the utility model is pivotally mounted on the second mold through the positioning seat so that the operating space is increased through the rotation of the positioning seat, which is more conducive to quickly placing and positioning the shoe outsole in the operating area and effectively avoiding the shoe outsole from being skewed or misaligned, and at the same time, it is also helpful to quickly take out the finished product shoes, thereby increasing the convenience of operation, improving the finished product yield, enhancing the operating efficiency, and greatly reducing the production cost.

[0051] The above description is only for explaining the preferred embodiment of the utility model, and it cannot be used to limit the scope of the implementation of the utility model. That is, all simple equivalent changes and modifications made according to the scope of the patent application of the utility model and the content of the utility model specification should still fall within the scope covered by the utility model patent.
