Description

Technical Field

[0001] This utility model relates to the field of shoe manufacturing technology, specifically to a shoe mold for one-piece molded shoes. Background Technology

[0002] Shoes are items worn on the feet to prevent injury. They have evolved from straw sandals and cloth shoes to leather shoes and sports shoes. Therefore, shoes are a necessity for people and an important tool for protecting the safety of their feet.

[0003] Traditional shoe-making molds require first placing a rubber outsole in the shoe sole molding cavity and then injecting foamed molding material. Next, the upper is placed on the shoe last, the mold is closed, adhesive is injected, and finally, it is heated to form the finished shoe. However, the manufacturing process of this type of finished shoe is cumbersome and complex, and its practicality is also relatively low. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a shoe mold for one-piece molded shoes, which solves the problem mentioned in the background art that traditional shoe molds require first placing a rubber outsole in the shoe sole molding cavity and injecting foamed molding outsole, then fitting the upper onto the shoe last, closing the mold and injecting adhesive, and finally heating and molding into a finished shoe. However, the manufacturing process of such finished shoes is cumbersome and complex, and their practicality is also low.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shoe mold for one-piece molded shoes, including a lower mold, four supporting legs fixedly installed at the bottom of the lower mold, the four supporting legs being arranged in a rectangular array at the bottom of the lower mold, an upper mold provided on the lower mold, two opposing lower cavities opened on the lower mold, two opposing upper cavities opened in the upper mold, a shoe last provided between the lower and upper cavities, two injection ports provided at the top of the upper mold, both of the two injection ports being connected to the upper cavities, two positioning posts fixedly installed on the upper surface of the lower mold near the front end, and two positioning holes opened on the upper mold near the front end.

[0006] Using the above technical solution, the lower mold is supported by four support legs installed at the bottom. When a one-piece molded shoe is to be made, the worker first places the shoe last into the lower cavity of the lower mold. Then, the worker closes the upper and lower molds, ensuring that the positioning pins installed on the lower mold are inserted into the positioning holes installed in the upper mold to prevent misalignment during mold closing. After the lower and upper molds are closed, the worker injects the rubber material into the cavity between the lower cavity, upper cavity, and shoe last through the injection port at the top of the upper mold. After the rubber material is molded into a finished shoe, the worker removes the restriction on the upper mold to separate the upper and lower molds. After the molded shoe is demolded from the lower cavity, the worker removes the molded shoe from the shoe last.

[0007] Preferably, the bottom of the lower mold has two connecting rods arranged opposite each other, both connecting rods extending through the lower mold into the lower cavity, the top ends of the two connecting rods are fixedly installed with top plates, and the bottom ends of the connecting rods are fixedly installed with connecting plates.

[0008] Using the above technical solution, the connecting plate drives the connecting rod to rise, so that the connecting rod pushes the molded shoes out of the lower cavity through the top plate.

[0009] Preferably, a first threaded rod passes through the connecting plate, the top end of the first threaded rod is rotatably engaged in the lower mold, and a first knob is fixedly installed at the bottom of the first threaded rod.

[0010] Using the above technical solution, the first knob drives the first threaded rod to rotate. When the first threaded rod rotates, it drives the connecting plate to lift the connecting rod, so that the connecting rod pushes the molded shoes out of the lower cavity through the top plate.

[0011] Preferably, connecting seats are fixedly installed on both ends of the lower mold, and a fixing plate is rotatably installed inside the connecting seat, with a sliding groove formed inside the fixing plate.

[0012] By adopting the above technical solution, the second screw rod at the bottom of the second knob is turned to drive the pressure plate to rise. Then, the operator rotates the fixing plate to make the fixing plate rotate to both sides, which can effectively prevent the pressure plate from affecting the opening of the upper mold when it is opened.

[0013] Preferably, a second threaded rod is provided in the slide groove, a second knob is fixedly installed at the top end of the second threaded rod, a pressure plate is provided in the slide groove, and the second threaded rod passes through the pressure plate.

[0014] By adopting the above technical solution, the second knob is rotated to drive the second threaded rod to rotate. Since the second threaded rod is equipped with a pressure plate, when the second threaded rod rotates, the pressure plate moves up and down in the groove of the fixed plate, thereby pressing the upper mold against the pressure plate to keep the mold closing between the upper mold and the lower mold stable.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The shoe mold for this one-piece molded shoe involves placing the shoe last into the lower cavity of the lower mold, then closing the upper and lower molds. Next, the rubber material is injected into the cavity between the lower cavity, upper cavity, and shoe last through the injection port at the top of the upper mold. After the rubber material is molded into a finished shoe, the first knob is rotated, causing the first threaded rod to rotate. This threaded rod then drives the connecting plate to rise, allowing the connecting rod to push the molded shoe out of the lower cavity through the top plate. After the molded shoe is demolded from the lower cavity, the worker can then remove the molded shoe from the shoe last.

[0017] 2. The shoe mold of this one-piece molded shoe uses a second knob to rotate a second threaded rod. Since the second threaded rod has a pressure plate, when the second threaded rod rotates, the pressure plate moves up and down in the groove of the fixed plate, thereby pressing the upper mold and keeping the mold closing between the upper and lower molds stable.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Referring to Figures 1-5, a shoe mold for a one-piece molded shoe is shown. Four supporting legs 2 are fixedly installed at the bottom of the lower mold 1, arranged in a rectangular array. An upper mold 3 is mounted on the lower mold 1. Two opposing lower cavities 4 are formed on the lower mold 1. Two opposing upper cavities 5 are formed within the upper mold 3. A shoe last 6 is positioned between the lower cavities 4 and the upper cavities 5. Two injection ports 7 are located at the top of the upper mold 3, both connected to the upper cavities 5. The upper surface of the lower mold 1 is closer to the front end. Two positioning posts 8 are fixedly installed in the upper mold 3. Two positioning holes 9 are opened on the upper mold 3 near the front end. Two connecting rods 10 are arranged opposite each other at the bottom of the lower mold 1. Both connecting rods 10 penetrate into the lower mold 1 and extend into the lower cavity 4. A top plate 11 is fixedly installed at the top of the two connecting rods 10. A connecting plate 12 is fixedly installed at the bottom of the connecting rods 10. A first threaded rod 13 penetrates through the connecting plate 12. The top of the first threaded rod 13 is rotatably engaged in the lower mold 1. A first knob 14 is fixedly installed at the bottom of the first threaded rod 13.

[0027] Working principle: The lower mold 1 is supported by four support legs 2 installed at the bottom. When a one-piece molded shoe is to be made, the worker first places the shoe last 6 into the lower cavity 4 opened in the lower mold 1. Then, the worker closes the upper mold 3 and the lower mold 1, ensuring that the positioning pins 8 installed on the lower mold 1 are inserted into the positioning holes 9 installed in the upper mold 3, thus preventing the upper mold 3 and the lower mold 1 from deviating during mold closing. After the lower mold 1 and the upper mold 3 are closed, the worker injects the rubber material into the space between the lower cavity 4, the upper cavity 5, and the shoe last 6 through the injection port 7 set at the top of the upper mold 3. Inside the cavity, after the rubber material is molded into a finished shoe, the workers remove the restriction on the upper mold 3 to separate the upper mold 3 and the lower mold 1. After the separation between the upper mold 3 and the lower mold 1 is completed, the workers turn the first knob 14 to drive the first threaded rod 13 to rotate. When the first threaded rod 13 rotates, it will drive the connecting plate 12 to drive the connecting rod 10 to rise, so that the connecting rod 10 pushes the molded shoes out of the lower cavity 4 through the top plate 11. After the molded shoes are demolded from the lower cavity 4, the workers can then take the molded shoes out of the shoe last 6.

[0028] Example 2:

[0029] Referring to Figures 1-5, a shoe mold for one-piece molded shoes is provided. Connecting seats 15 are fixedly installed on both end faces of the lower mold 1. A fixing plate 16 is rotatably installed inside the connecting seat 15. A sliding groove 17 is opened in the fixing plate 16. A second threaded rod 18 is provided in the sliding groove 17. A second knob 19 is fixedly installed at the top of the second threaded rod 18. A pressure plate 20 is provided in the sliding groove 17. The second threaded rod 18 passes through the pressure plate 20.

[0030] Working principle: After the lower mold 1 and the lower die 1 are closed, the operator rotates the second knob 19, which in turn drives the second threaded rod 18 to rotate. Since the second threaded rod 18 is equipped with a pressure plate 20, when the second threaded rod 18 rotates, the pressure plate 20 moves up and down in the groove 17 of the fixed plate 16, thereby pressing the upper mold 3 against it. This keeps the mold closing between the upper mold 3 and the lower mold 1 stable. Since the fixed plate 16 is rotatably installed in the rotating seat, when the upper mold 3 is opened, the operator rotates the second knob 19, which causes the second threaded rod 18 at the bottom of the second knob 19 to drive the pressure plate 20 to rise. Then, the operator rotates the fixed plate 16, which rotates the fixed plate 16 to both sides. This effectively prevents the pressure plate 20 from affecting the opening of the upper mold 3.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
