Description

Technical Field

[0001] This utility model relates to the field of corner protector mold technology, specifically a 90-degree corner protector mold for plant fibers. Background Technology

[0002] Plant fiber 90-degree corner protectors are an environmentally friendly packaging material mainly used for product edge protection. They are characterized by pressure resistance, moisture resistance, and lightweight. The production and processing of plant fiber corner protectors requires the use of appropriate molds. However, during the production process, because plant fibers are mostly filamentous or flocculent, uneven heating can easily occur during the heating and molding process. This causes the plant fibers closer to the heating pipe to melt rapidly, while the fibers further away from the heating pipe melt more slowly. Consequently, the plant fibers closer to the heating pipe may scorch, affecting product quality. Furthermore, demolding the molded corner protectors is inconvenient.

[0003] Based on this, a 90-degree corner protector mold for plant fibers is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0004] The purpose of this invention is to provide a 90-degree corner protector mold for plant fibers to solve the problems in the background art.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] In one embodiment, such as Figures 1-5 As shown, a 90-degree corner protector mold for plant fibers includes an upper fixing plate 1. An upper template 11 is provided at the bottom end of the upper fixing plate 1. Internally threaded holes are evenly distributed on the upper fixing plate 1, and first fixing bolts 12 are threadedly connected to the internally threaded holes on the upper template 11. A lower template 14 is provided at the bottom end of the upper template 11. A protective component 2 is provided at the top end of the lower template 14. A pad 16 is provided at the bottom end of the lower template 14. A lower fixing plate 17 is provided, and a long bolt is provided inside the lower fixing plate 17. The long bolt passes through the positioning hole of the pad plate 16 and is threadedly connected to the lower template 14. A pin plate 18 is provided at the top of the lower fixing plate 17. A guide block 19 is fixedly connected to the top of the lower fixing plate 17 by bolts. The guide block 19 is slidably connected to a rectangular groove opened on the pin plate 18. A circular through hole is opened at the bottom of the lower fixing plate 17 for ejecting the pin plate 18 upward. An ejection mechanism 3 is provided at the top of the pin plate 18.

[0023] In this embodiment, the protective component 2 blocks the special material during the feeding process to prevent it from scattering. This prevents the special material from overflowing during subsequent mold closing. After pressing and molding, the mold is opened, and then the molded corner protectors are ejected by the ejection mechanism 3 in conjunction with the external drive.

[0024] In an optional embodiment, such as Figure 3 As shown, the upper template 11 is provided with first heating holes 13 evenly distributed, and the top of the special material is heated through the first heating holes 13.

[0025] In an optional embodiment, such as Figure 4As shown, the lower template 14 is provided with a second heating hole 15. The bottom of the special material is heated through the second heating hole 15, which, together with the first heating hole 13, heats the special material evenly and speeds up its molding process.

[0026] In an optional embodiment, such as Figure 4 As shown, the top surface of the lower template 14 has a 90-degree triangular groove that matches the bottom shape of the upper template 11. So when the special material is quantitatively poured into the 90-degree triangular groove on the lower template 14 and the mold is closed, the area between the lower template 14 and the 90-degree triangular groove is the shape of the corner protector after molding.

[0027] In an optional embodiment, such as Figure 4 As shown, the protective component 2 includes two first baffle plates 21 and two second baffle plates 22. The bottom end of the first baffle plate 21 contacts the top end of the lower template 14, and the bottom end of the second baffle plate 22 contacts the top end of the lower template 14. Countersunk holes are evenly provided on the first baffle plate 21 and the second baffle plate 22, and a second fixing bolt 23 is provided in the countersunk hole. The second fixing bolt 23 is threadedly connected to the internal threaded hole on the lower template 14. By connecting the first baffle plate 21 and the second baffle plate 22 to the lower template 14, the special material is prevented from scattering when it is poured into the 90-degree triangular groove.

[0028] In an optional embodiment, such as Figure 5 As shown, the ejection mechanism 3 includes a fixing block 31. The bottom end of the fixing block 31 is fixedly connected to the top end of the ejector plate 18 by bolts. An ejector pin 32 is fixedly connected to the top end of the fixing block 31. The ejector pin 32 is slidably connected to the ejector pin hole opened on the lower template 14. An external drive mechanism (cylinder or electric telescopic rod) passes through the circular through hole at the bottom of the lower fixing plate 17 and pushes the ejector plate 18 upward. The guide block 19 moves and guides the ejector plate 18 to prevent the ejector plate 18 from deviating. At the same time, the ejector plate 18 drives the fixing block 31 and the ejector pin 32 to move synchronously, so that the ejector pin 32 ejects the 90-degree corner protector that has been pressed and formed.

[0029] In an optional embodiment, such as Figure 5 As shown, the top working surface of the ejector pin 32 has a groove that matches the bottom shape of the 90-degree triangular groove of the lower template 14. In this way, during the hot pressing stage, the ejector pin 32 seals the special material in the 90-degree triangular groove to prevent leakage, and at the same time facilitates its subsequent ejection.

[0030] The above embodiment discloses a 90-degree corner protector mold for plant fibers. When processing the 90-degree corner protector (hereinafter referred to as the corner protector), a measured amount of the required special material (plant fiber mixture) is poured into a 90-degree triangular groove on the lower mold plate 14. The special material is blocked by the first baffle plate 21 and the second baffle plate 22 to prevent it from scattering. Then, the mold is closed, allowing the upper mold plate 11 to enter the 90-degree triangular groove. An external heating device heats the special material in the 90-degree triangular groove through the first heating hole 13 and the second heating hole 15, and presses it into shape using the upper mold plate 11. When the pressing time reaches a preset time, pressing is stopped, and then the mold is opened. Move the upper template 11 away from the lower template 14, and then push the ejector plate 18 upward through the circular through hole at the bottom of the lower fixed plate 17 via an external drive mechanism (cylinder or electric telescopic rod). The guide block 19 moves and guides the ejector plate 18 to prevent it from shifting. At the same time, the ejector plate 18 drives the fixed block 31 and the ejector 32 to move synchronously, so that the ejector 32 ejects the 90-degree corner protector that has been pressed and formed, thus completing one processing step. In summary, the protective component 2 blocks the special material during material feeding to prevent it from scattering. During subsequent mold closing, the special material is prevented from overflowing. After pressing and forming, the mold is opened, and then the ejector mechanism 3, in conjunction with the external drive, ejects the formed corner protector.

[0031] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
