Description

Technical Field

[0001] This utility model belongs to the field of plastic panel molding technology, and in particular relates to a partial three-dimensional molding mold for a plastic light-shielding display panel. Background Technology

[0002] Plastic light-shielding display panels are a type of display panel made of plastic materials. They are lightweight and flexible, while also providing light-shielding functionality. This effectively reduces the interference of external light on the screen display effect and improves visibility. Most existing plastic light-shielding display panels are single-plane panels. Their processing flow is usually as follows: first, the flat plastic sheet is mechanically shaped into a certain planar shape; then, a light-shielding layer is added through overall coating or lamination; finally, the light-shielding layer is cured by high temperature or ultraviolet light. These panels mainly rely on the planar structure to achieve basic light-shielding functions and are widely used in various devices with simple requirements for the shape of the display panel, such as early monitors and general medical monitoring equipment.

[0003] However, in actual processing, existing panel molding technology can only produce flat panels and cannot meet the design requirements of local irregular structures (such as curved surfaces and corner transitions). There is a gap between this technology and the aesthetic design and functional compatibility of modern equipment. For example, in order to improve the ease of operation and visual coordination, the shading position of the CT machine display screen needs to be a curved three-dimensional transition. However, existing technology cannot achieve this structure and can only achieve it by splicing flat panels, which affects the overall appearance of the equipment. Therefore, a new type of plastic shading display screen panel local three-dimensional molding mold is needed to solve the above problems. Utility Model Content

This solves the problem that the prior art can only produce flat panels and cannot meet the design requirements of partial irregular structures, resulting in poor functional adaptability and design aesthetics of the panels.

Detailed Implementation

[0021] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0022] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] refer to Figures 1 to 4 This utility model provides a partial three-dimensional molding mold for a plastic light-shielding display panel, including a base plate 1. A support rod 2 is fixedly connected to the bottom of the base plate 1. A positioning mechanism is provided above the base plate 1. An upper mold 3 and a lower mold 4 are slidably positioned on the positioning mechanism. The upper mold 3 is located directly above the lower mold 4. A special-shaped assembly part 5 is provided on the side of the upper mold 3 and the lower mold 4 that are close to each other. A limiting baffle 6 for restricting the position of the plastic substrate is fixedly connected above the lower mold 4. Several first quick-pressing clamps 7 for pressing the upper mold 3 and the lower mold 4 are provided above the base plate 1 on the left, right and rear sides of the lower mold 4. Several opening slots 8 are symmetrically opened on the left and right sides of the upper mold 3. Several second quick-pressing clamps 9 for positioning the plastic substrate are symmetrically arranged above the lower mold 4. The positions of the second quick-pressing clamps 9 correspond to the opening slots 8.

[0024] In use, the plastic substrate is first locally heated and softened at the location to be formed. Then, the partially softened plastic substrate is placed on the lower mold 4, with the softened part located at the irregular mold assembly part 5 on the lower mold 4. During this process, the plastic substrate can be initially limited by the limiting baffle 6, and the unsoftened part of the plastic substrate is pressed by the second quick-pressing clamp 9 to stabilize and fix the plastic substrate, preventing it from moving during the forming process and affecting the forming quality. Then, the upper mold 3 is closed with the lower mold 4 under the limitation of the positioning mechanism, and the upper mold 3 is pressed by the first quick-pressing clamp 7 to make the upper mold 3 and the lower mold 4 fit tightly. The softened part of the plastic substrate will be formed under the cooperation of the irregular mold assembly part 5. After the plastic substrate cools and solidifies, the above operation can be reversed to remove the processed plastic substrate.

[0025] This setup allows for the use of the upper mold 3, lower mold 4, and irregularly shaped assembly part 5 to process panels with local irregular structures, thereby effectively improving the functional adaptability and design aesthetics of the panel and ensuring that the panel can meet different usage needs. At the same time, by locally heating and softening the plastic substrate and molding it, the cracking and peeling of the light-shielding layer caused by overall heating of the substrate can be avoided, thus effectively improving the light-shielding effect of the panel.

[0026] It should be noted that both the upper mold 3 and the lower mold 4 are made of bakelite, which is heat-resistant and has good heat insulation properties. Furthermore, the mating surfaces of the upper mold 3 and the lower mold 4 are covered with ultra-fine dust-free cloth to prevent scratching the surface of the plastic substrate.

[0027] Furthermore, the positioning mechanism includes a plurality of positioning rods 10 symmetrically fixedly connected to the top of the base plate 1, a plurality of first positioning holes 11 symmetrically opened on the lower mold 4, the positioning rods 10 being slidably inserted into the first positioning holes 11, a plurality of positioning sleeves 12 symmetrically fixedly connected to the top of the upper mold 3, the positioning sleeves 12 being provided with second positioning holes 13 penetrating the positioning sleeves 12 and the upper mold 3, the positioning rods 10 being slidably inserted into the second positioning holes 13.

[0028] During use, the lower mold 4 and the upper mold 3 are positioned by the positioning rod 10, thereby ensuring that the upper mold 3 and the lower mold 4 can be accurately fitted, avoiding errors in the fitting that would affect the panel forming quality. When placing and removing the plastic substrate, the upper mold 3 can be directly removed from the positioning rod 10, thereby effectively improving the ease of operation of the equipment and ensuring efficient panel processing.

[0029] Furthermore, the first quick-press clamp 7 includes a fixed base 14 fixedly connected to the top of the base plate 1. Two mounting plates 15 are symmetrically fixedly connected to the top of the fixed base 14. A connecting plate 16 is rotatably connected between the two mounting plates 15 near the lower mold 4. A mounting rod 17 is fixedly connected to the side of the connecting plate 16 near the lower mold 4. A first pressing head 18 that can adjust the pressing position is provided on the mounting rod 17. A connecting rod 19 is rotatably connected between the two mounting plates 15 away from the lower mold 4. A drive rod 20 is symmetrically rotatably connected to both sides of the end of the connecting rod 19 away from the mounting plate 15. The end of the drive rod 20 near the connecting plate 16 is rotatably connected to the connecting plate 16. The ends of the two drive rods 20 away from the connecting plate 16 are fixedly connected to the same handle 21.

[0030] After the upper mold 3 and lower mold 4 are closed, the handle 21 is twisted downwards simultaneously and quickly. This will cause the connecting plate 16 to rotate around the point where it is connected to the mounting plate 15. This will cause the mounting rod 17 to drive the first pressing head 18 to press the upper mold 3 downwards, making the upper mold 3 and lower mold 4 fit tightly together. When it is necessary to remove the cooled and shaped plastic substrate, the handle 21 is twisted upwards, and the first pressing head 18 will be driven to rise, so that the upper mold 3 can be removed. Furthermore, the position of the first pressing head 18 can be adjusted according to the actual pressing requirements, thereby further improving the processing effect of the equipment.

[0031] This setting allows the first pressing head 18 to press the upper mold 3 quickly from multiple directions, thereby ensuring convenient operation of the equipment while effectively improving the bonding effect between the upper mold 3 and the lower mold 4, and ensuring high-quality processing of the panel.

[0032] Furthermore, the mounting rod 17 is provided with a sliding groove 22, and a sliding screw 23 is slidably disposed in the sliding groove 22. Baffles 24 are symmetrically disposed on both sides of the mounting rod 17. The baffles 24 are sleeved on the outside of the sliding screw 23. An adjusting nut 25 is disposed on the side of the two baffles 24 that are far apart from each other. The adjusting nut 25 is threadedly connected to the sliding screw 23. The first pressing head 18 is fixedly connected to the end of the sliding screw 23 near the lower mold 4.

[0033] During normal use, the adjusting nut 25 presses the baffle 24 against both sides of the mounting rod 17, preventing the sliding screw 23 from driving the first pressing head 18 to slide within the groove 22, thus ensuring stable pressing of the upper mold 3. When it is necessary to adjust the position of the first pressing head 18, rotate the adjusting nut 25 to move it away from the mounting rod 17, thereby loosening the baffle 24. At this time, the sliding screw 23 and the first pressing head 18 can be moved directly to adjust the pressing position of the first pressing head 18. After adjustment, reset the adjusting nut 25, and the sliding screw 23 and the first pressing head 18 can be relocked for pressing.

[0034] This setting allows for rapid adjustment of the pressing position of the first pressing head 18 using the adjusting nut 25, sliding screw 23, and baffle 24. This improves the ease of use of the equipment while ensuring that the equipment can be adjusted according to actual processing needs, thereby effectively improving the processing and usage effects of the equipment.

[0035] Furthermore, the second quick-press clamp 9 has the same structural principle as the first quick-press clamp 7, and it includes a second pressing head 26 for pressing and positioning the plastic substrate.

[0036] In use, the locally heated and softened plastic substrate is placed on the lower mold 4. At this time, the first quick-pressing clamp 7 drives the second pressing head 26 to move downward, thereby pressing and fixing the unheated part of the plastic substrate exposed from the opening slot 8. In addition, the position of the second pressing head 26 can be adjusted in the same way as the first pressing head 18. In use, the pressing position of the second pressing head 26 can be adjusted according to the size of the plastic substrate and the applicability of the processing requirements.

[0037] This setting allows the second pressing head 26 to stably fix plastic substrates with different processing requirements, thereby effectively preventing displacement of the plastic substrate during the molding process and affecting the panel molding quality, ensuring high-quality processing by the equipment.

[0038] The working principle of this utility model:

[0039] In use, the plastic substrate is first locally heated and softened at the location to be formed. Then, the partially softened plastic substrate is placed on the lower mold 4, with the softened part located at the irregular mold assembly part 5 on the lower mold 4. During this process, the plastic substrate can be initially limited by the limiting baffle 6, and the unsoftened part of the plastic substrate is pressed by the second quick-pressing clamp 9 to stabilize and fix the plastic substrate, preventing it from moving during the forming process and affecting the forming quality. Then, the upper mold 3 is closed with the lower mold 4 under the limitation of the positioning mechanism, and the upper mold 3 is pressed by the first quick-pressing clamp 7 to make the upper mold 3 and the lower mold 4 fit tightly. The softened part of the plastic substrate will be formed under the cooperation of the irregular mold assembly part 5. After the plastic substrate cools and solidifies, the above operation can be reversed to remove the processed plastic substrate.
