DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Please refer to Figures 1 - 6 , a release film laminating mold, including a base plate 1 and a base 2. A lower mold fixing layer 8 is fixedly installed at the upper end of the base 2. A lower mold groove 14 is opened at the upper end of the lower mold fixing layer 8. A lower mold 9 is slidably installed in the lower mold groove 14. Support columns 3 are fixedly installed at the four corners of the upper end of the base 2. The support columns 3 are respectively located at the four corners of the base 2 to ensure the stable connection between the top seat 4 and the base 2. A top seat 4 is fixedly installed at the upper end of the support column 3. A driving motor 5 is fixedly installed at the upper end of the top seat 4. The driving motor 5 drives the rotation of a threaded rod 6 through an output shaft, thereby controlling the up and down movement of the upper mold fixing layer 10 and the upper mold 11. The output end of the driving motor 5 is fixedly installed with a threaded rod 6. The threaded rod 6 is directly connected to the output end of the driving motor 5. By rotating, it drives the upper mold fixing layer 10 to perform a lifting movement. The threaded rod 6 is threadedly installed with an upper mold fixing layer 10. The upper mold fixing layer 10 has a threaded hole matching the threaded rod 6, and a bolt hole for installing the upper mold 11. A first bolt 15 is threadedly installed at the bottom of the upper mold fixing layer 10. The first bolt 15 connects the upper mold 11 and the upper mold fixing layer 10 to ensure that the upper mold 11 does not loosen under high pressure. The upper mold 11 is threadedly installed between the first bolt 15 and the upper mold fixing layer 10. A release film member 7 is fixedly installed on one side of the base plate 1. Second bolts 13 are threadedly installed at the four corners of the lower mold groove 14 and the lower mold 9. An operation panel 12 is fixedly installed at one end of the base 2.

[0021] During use, install the mold at a designated position to ensure that all components are tightly connected. Press the start button on the operation panel 12, and the driving motor 5 starts to work. Drive the upper mold fixing layer 10 and the upper mold 11 to slowly descend through the threaded rod 6 until they are in close contact with the lower mold 9. Inject the release film into the mold through the release film member 7. After the product cools and solidifies, the driving motor 5 rotates in reverse, and the upper mold 11 rises under the drive of the threaded rod 6 and separates from the lower mold 9. At this time, the auxiliary function of the release film member 7 enables the product to be smoothly removed from the lower mold 9, reducing scratches and damage. The degree of automation is high, reducing manual intervention and significantly improving production efficiency. Through the lower mold 9 and the upper mold 11 whose positions can be precisely adjusted, the pressure distribution during the laminating process can be more effectively controlled, which helps to reduce the phenomena of bubbles, wrinkles or incomplete coverage. Through the detachable upper mold 11 and lower mold 9, the staff can replace the mold according to needs, which is convenient for replacing different models and improves the flexibility of the production line. The use of the release film member 7 reduces the damage to the product during demolding, reduces the rejection rate, and at the same time, the durability of the mold also reduces the maintenance cost. The mold can be replaced and adjusted according to the needs of different products, realizing multi-purpose use of one machine, and improving the utilization rate and flexibility of the equipment.

[0022] As Figure 5 or Figure 6 shown, the release film component 7 is fixedly installed on one side of the base plate 1 with a placement rack 701, a release film roll 702, a conveying rod 703, a positioning column 704, a bearing rod 705, and a stepping motor 706. The bearing rod 705 is fixedly installed through the release film roll 702. The bearing rod 705 is placed on the placement rack 701. The bottom of the positioning column 704 is fixedly installed on one side of the base 2. The stepping motor 706 is fixedly installed on one side of the positioning column 704. The output end of the stepping motor 706 is fixedly connected to one end of the conveying rod 703. The conveying rod 703 is rotatably installed between the positioning columns 704. During the above use process, the stepping motor 706 is started through the operation panel 12 or an external control device. After receiving the instruction, the stepping motor 706 starts to rotate, driving the conveying rod 703 to rotate synchronously. As the conveying rod 703 rotates, the release film on the release film roll 702 is gradually unwound and conveyed forward. Guided by the conveying rod 703, the release film accurately covers the lower mold 9, preparing for the subsequent film covering operation. After the release film covers the lower mold 9, operations such as mold closing, injection molding, or forming are carried out according to the usage instructions of the above-mentioned mold. The presence of the release film helps to reduce the direct contact between the product and the mold, reducing the risk of scratches and damage. The automatic conveying and covering of the release film are realized by the drive of the stepping motor 706, reducing manual intervention and labor intensity, and improving the degree of production automation. The automatic release film conveying system can ensure the continuity and stability of the release film during the film covering process, thus improving production efficiency. The use of the release film reduces the direct contact and friction between the product and the mold, reducing the risk of scratches and damage, and helping to ensure the appearance quality and surface finish of the product.

[0023] As Figure 2 shown, the lower mold 9 and the upper mold 11 are matched in shape and size. During the above use process, the shapes and sizes of the lower mold 9 and the upper mold 11 are completely matched, ensuring the accuracy and consistency of product forming. The rapid mold closing and separation of the mold and the automated production process significantly improve production efficiency.

[0024] As Figure 1 shown, the operation panel 12 is electrically connected to the drive motor 5 and the release film component 7. During the above use process, the centralized control function of the operation panel 12 enables all links of the production process to be closely connected and work together, thus improving production efficiency, reducing manual intervention and waiting time, and further enhancing the production speed.

[0025] As Figure 4As shown, vacuum suction holes are provided in both the lower mold 9 and the upper mold 11. During the above-mentioned use process, the vacuum suction holes tightly fix the raw materials or semi-finished products on the mold surface through negative pressure adsorption, effectively preventing their movement or deformation during the molding process, helping to reduce the risk of scratches and damage on the product surface, and the automated control improves the continuity and stability of the production line, thereby improving production efficiency.
