Description

Technical Field

[0001] This utility model relates to the field of injection molding shoe mold technology, specifically to a shoe last with anti-pollution function. Background Technology

[0002] In the internal injection shoe last process, material is injected through the injection port at the top rear of the shoe last. The material then enters the mold cavity through the material channel to form the shoe product. Usually, immediately after injection, a small amount of material is still in a liquid state at the injection port, which may overflow and drip onto the shoe product, affecting the smoothness of the shoe product's surface and causing defects in the product.

[0003] Currently, to avoid material contamination, most manufacturers make the injection port of the shoe last thicker, keeping the injection port away from the shoe product. While this allows for production, it makes shoe last manufacturing more difficult. Installing the feed tube and drilling a matching hole in the shoe last are also challenging. Furthermore, the feed tube may protrude from the shoe last, affecting the style of products with high shoe shafts. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a shoe last with anti-pollution functionality. By installing an anti-overflow component, when the casting is complete, excess uncured filler will flow down along the anti-overflow component and move away from the shoe body, preventing adhesion to the shoe body and ensuring a high yield rate for shoe body molding.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a shoe last with anti-pollution function, comprising a shoe last body, a casting block disposed above the shoe last body, a casting channel extending to the bottom of the shoe last body disposed within the casting block, a casting port communicating with the casting channel disposed on the side wall of the casting block, and an anti-overflow component disposed outside the casting port.

[0006] As a further improvement to the above technical solution:

[0007] The overflow prevention component includes a connecting plate and a guide plate, wherein the guide plate is inclined.

[0008] The connecting plate is detachably connected to the casting block, and the middle part of the connecting plate is provided with a through hole corresponding to the position of the casting port.

[0009] The connecting plate and the casting block are detachably connected by bolts, and the connecting plate is provided with threaded holes located around the through hole.

[0010] The front side of the casting block is provided with a hook for connecting to the shoe machine. The hook includes a positioning plate and an extension plate arranged in an L-shape.

[0011] The positioning plate and the casting block are detachably connected.

[0012] The beneficial effects of this utility model embodiment are as follows: The shoe last with anti-pollution function includes a shoe last body, a casting block is provided on the top of the shoe last body, and a casting channel extending to the bottom of the shoe last body is provided in the casting block. The casting channel is designed at an inclination and passes through the shoe last body and the casting block. A casting port connected to the casting channel is provided on the side wall of the casting block. An anti-overflow component is provided outside the casting port. When the casting is completed, the excess uncured casting filler will flow down along the anti-overflow component and away from the shoe body to avoid sticking to the shoe body and ensure the yield of shoe body molding. At the same time, the design of the guide plate can guide the excess casting filler to a position away from the shoe body and can also recycle the excess casting filler, reducing the waste of production materials.

[0017] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0018] like Figure 1-3 As shown, the shoe last with anti-pollution function in this embodiment includes a shoe last body 1, a casting block 2 on the top of the shoe last body 1, a casting channel 3 extending to the bottom of the shoe last body 1 inside the casting block 2, the casting channel 3 being inclined and penetrating the shoe last body 1 and the casting block 2, a casting port 4 connected to the casting channel 3 being provided on the side wall of the casting block 2, an anti-overflow component 5 being provided outside the casting port 4, the anti-overflow component 5 including a connecting plate 6 and a guide plate 7, the guide plate 7 being inclined, during the casting of filler, the filler enters the casting channel 3 through the casting port 4, forming the cast shoe body between the shoe last body 1 and the mold, when the casting is completed, the excess uncured filler will flow down along the anti-overflow component 5 and away from the shoe body, avoiding adhesion to the shoe body, ensuring the yield of the shoe body molding, and at the same time, the design of the guide plate 7 can guide the excess filler to a position away from the shoe body, and can also recycle the excess filler, reducing the waste of production materials.

[0019] It should be emphasized that the shoe last body 1 can be hollow or solid. The casting channel 3 inside the shoe last body 1 can be one or multiple, depending on the production needs in actual use. The shoe last body 1 can adopt an integral design or a split splicing design.

[0020] The connecting plate 6 and the casting block 2 are detachably connected by bolts, or they can be connected by adhesive or magnetic attraction, which facilitates the replacement and maintenance of the overflow prevention component. The middle part of the connecting plate 6 is provided with a through hole 14 corresponding to the position of the casting port 4. The connecting plate 6 is provided with threaded holes 8 located around the through hole 14. The connecting plate 6 and the guide plate 7 can be an integral structure or a separate structure.

[0021] The front side of the casting block 2 is equipped with a hook 11 that interacts with the top rod of the shoe machine. The hook 11 includes a positioning plate 12 and an extension plate 13 arranged in an L-shape. The positioning plate 12 is detachably connected to the casting block 2 by bolts.

[0022] In use, the shoe last body 1 and the casting block 2 are integrally formed. The front and rear sides of the casting block 2 are ground flat. The hanging part 11 is installed on the front side of the casting block 2 with bolts, and the anti-overflow part 5 is installed on the rear side with bolts, ensuring that the through hole 14 and the casting port 4 correspond. The shoe machine hangs and connects the shoe last body 1, and then the shoe last body 1 is placed in the mold. The filling material is filled through the casting port 4. When the filling material is filled, the excess filling material will flow out along the anti-overflow part 5 when it overflows, avoiding adhesion to the shoe body. At the same time, the excess material can be recycled and reused.

[0023] Another way to eliminate material overflow from contaminating the shoe upper is to install a material receiving plate at the injection end of the shoe mold, around the material head of the shoe machine, or at the turntable station of the shoe machine.
