[0031] Example

[0032] Reference Figure 1 The cover plate 70 shown has a scratch-resistant film on its surface, several buckles 702 on one side of the cover plate 70, and an edge groove 701 on the other side edge.

[0033] Reference Figure 2 As shown, this utility model discloses a mold with a clamping structure, including a panel 10, an upper ejector plate 20, an upper template 30, a lower template 40, a lower ejector plate 50, and a base plate 60 from top to bottom. An upper mold core 301 is embedded at the bottom of the upper template 30, and a lower mold core 401 is embedded in the lower template 40. The upper mold core 301 has an upper forming groove 3011, and the lower mold core 401 has a lower forming groove 4011. When the mold is closed, the upper template 30 and the lower template 40 close, and the upper forming groove 3011 and the lower forming groove 4011 close to form the cavity of the forming cover plate 70.

[0034] Reference Figure 3-7 As shown, the upper mold plate 30 has a forming plate 201 on one side of the upper forming groove 3011. The forming plate 201 has a groove on its end face facing the upper forming groove 3011. A slanted rod is provided at the bottom of the forming plate 201, which slidably passes through the upper mold plate 30 and connects to the upper ejector plate 20. Specifically, during mold closing and injection molding, the forming plate 201 is placed on one side of the upper forming groove 3011, and the groove is used to form the edge groove 701 on one side of the cover plate 70. Further, the upper mold core 301 has a push block 202 on one side of the upper forming groove 3011. The push block 202 has a side forming groove on its side facing the upper forming groove 3011, and its upper end slidably passes upward through the upper mold core 301 and the upper mold plate 30 to connect to the upper ejector plate 20. During mold closing and injection molding, the side forming groove is used to form the undercut 702 of the cover plate 70.

[0035] Reference Figure 3-7As shown, hydraulic cylinders 302 are set on both sides of the upper mold plate 30. The piston rod of the hydraulic cylinder 302 is connected to the upper ejector plate 20. Specifically, when the mold is opened, the upper mold plate 30 and the lower mold plate 40 are separated. The hydraulic cylinder 302 is controlled to push the upper ejector plate 20 upward, which drives the inclined rod connected to the forming plate 201 to move obliquely upward, and the groove is disengaged from the edge groove 701. At the same time, the upper ejector plate 20 drives the push block 202 to move obliquely upward, which drives the side forming groove to disengage from the undercut 702 to realize the demolding of the structures on both sides of the cover plate 70.

[0036] Reference Figure 3-7 As shown, a frame 502 is provided on the lower mold core 401, and a push rod 501 is provided on the lower ejector plate 50. A spring 503 is sleeved on the push rod 501. The upper end of the push rod 501 slides upward through the lower mold plate 40 and connects to both sides of the frame 502. Specifically, before mold closing, the lower ejector plate 50 is pushed upward to push the frame 502 away from the lower mold core 401. Then, the film is passed between the frame 502 and the lower mold core 401. The lower ejector plate 50 is released, and under the action of the spring 503, the ejector plate is pushed towards the base plate 60, causing the frame 502 to press the film to cover the lower mold core 401. When the upper mold plate 30 and the lower mold plate 40 are closed, the upper forming groove 3011 and the lower forming groove 4011 close simultaneously, pressing the film. After injection molding the cover plate 70, the film covers the cover plate 70, realizing the molding of the cover plate 70 while the film is adhered to the cover plate 70, simplifying the molding process of the cover plate 70 and improving work efficiency.

[0037] In this embodiment, the frame 502 is formed by connecting four pressure rods end to end. Two oppositely arranged pressure blocks are connected by connecting blocks, which are connected to push rods 501. The assembled frame 502 is convenient for installation and debugging.

[0038] In addition, the base plate 60 has several through holes, and the bottom of the lower ejector plate 50 is provided with ejector rods. The ejector rods pass through the through holes and push the lower ejector plate 50 upward to push the frame 502 away from the lower mold core 401. The ejector rods extending out of the base plate 60 can be easily connected to external lifting hydraulic cylinders to automatically push the lower ejector plate 50.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
