[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4 The present invention provides a technical solution as follows:
[0022] Example 1:
[0023] An easily adjustable IMD mold positioning mechanism includes a frame 1, a support plate 2 fixedly connected to the outer wall of the frame 1, a drive assembly 3 fixedly mounted on the outer wall of the support plate 2, an upper mold mounting seat 4 mounted on the output end of the drive assembly 3, a positioning cylinder 5 fixedly connected to the outer wall of the support plate 2, a limiting plate 6 fixedly connected to the output end of the positioning cylinder 5, a conveyor belt 7 installed inside the frame 1, a guide rail 8 installed on the inner side of the frame 1, and a positioning assembly 9 slidably mounted on the outer wall of the guide rail 8.
[0024] The above structure facilitates the adjustment of the docking height of the upper and lower molds through the drive component 3, so that the docking distance can be adjusted according to the size of different molds. At the same time, during the mold installation and debugging stage, the adjustable limiting plate 6 allows technicians to quickly and accurately adjust the various parts of the mold to the appropriate position, reducing debugging time.
[0025] Furthermore, the drive assembly 3 includes a housing 301, a drive motor 302, a lead screw 303, and a movable block 304. The housing 301 is fixedly connected to the outer wall of the support plate 2, and the drive motor 302 is fixedly connected to the inner wall of the housing 301. The output shaft of the drive motor 302 is fixedly connected to the lead screw 303 via a coupling. The movable block 304 is threadedly connected to the outer wall of the lead screw 303. The movable block 304 is connected to the outer wall of the upper mold mounting base 4, and the upper mold mounting base 4 is located above the limiting plate 6.
[0026] The above structure drives the lead screw 303 to rotate via the drive motor 302, thereby causing the movable block 304 to move.
[0027] Furthermore, the internal components of the positioning assembly 9 include a junction box 901, a positioning seat 902, an iron core 903, a coil 904, a suction cup 905, a panel 906, a positioning plate 907, and a lower mold base 908. The junction box 901 is installed inside the frame 1. The positioning seat 902 is fixedly connected inside the frame 1. The iron core 903 is fixedly connected to the top of the positioning seat 902. The coil 904 is installed on the top of the iron core 903. The suction cup 905 is provided on the outer wall of the coil 904. The positioning plate 907 is slidably installed on the outer wall of the guide rail 8. The panel 906 is fixedly connected to the bottom of the positioning plate 907. The lower mold base 908 is fixedly connected to the top of the positioning plate 907.
[0028] The above structure can be positioned by the positioning component 9. Electromagnetic positioning can be used to achieve high-precision alignment between mold components by precisely controlling the magnetic field. In IMD molds, it can ensure that components such as films and inserts are accurately positioned in preset positions when the mold is closed.
[0029] Furthermore, the junction box 901 is connected to the positioning seat 902 via a line, and multiple sets of iron cores 903 are installed on the top of the positioning seat 902. The outer wall of the iron core 903 is wound with coils 904, and the suction cup 905 corresponds to the position of the panel 906. The positioning plate 907 is located above the positioning seat 902, and the positioning seat 902 is located below the upper mold mounting seat 4.
[0030] The above structure can provide a certain buffering and shock absorption effect through the action of magnetic force. When the upper mold mounting base 4 and the lower mold base 908 are closed, rigid collisions between components can be avoided, and the impact force on the mold and equipment during operation can be reduced.
[0031] Working principle: When in use, firstly, the IMD mold is made by placing the pre-printed patterned film sheet into the mold. Through injection molding and other processes, the plastic and the film sheet are tightly bonded together to form a decorative pattern or functional structure on the surface of the plastic product. The required upper and lower molds are respectively installed inside the upper mold mounting base 4 and the lower mold base 908.
[0032] Secondly, the drive component 3 facilitates the adjustment of the docking height between the upper and lower molds, allowing the docking distance to be adjusted according to the size of different molds. During the mold installation and debugging phase, the drive motor 302 drives the lead screw 303 to rotate, thereby causing the movable block 304 to move along the outer shell 301, allowing the upper mold mounting base 4 to be adjusted up and down. The adjustable limiting plate 6 allows technicians to quickly and accurately adjust each component of the mold to the appropriate position, reducing debugging time. Compared with molds that are difficult to position and adjust, it can significantly shorten the start-up preparation time and speed up the production process.
[0033] Finally, positioning can be achieved through the positioning component 9. Electromagnetic positioning utilizes the precise control of the magnetic field. The iron core 903 is usually made of stacked high-permeability silicon steel sheets to concentrate the magnetic flux and increase the attraction force. The coil 904 is the key to generating the magnetic field, which is achieved by passing current, thereby causing the suction cup 905 to generate attraction force. When the conveyor belt 7 transports the lower mold seat 908 to the corresponding position, it attracts the panel 906. The high-precision alignment between the mold components ensures that the film, inserts and other components are accurately positioned in the preset position when the mold is closed in the IMD mold. The positioning accuracy can reach the micron level, which is a significant improvement compared to the traditional mechanical positioning method, thereby ensuring the dimensional accuracy and appearance quality of the product. During the positioning process, the magnetic field force can play a certain role in buffering and shock absorption. When the upper mold mounting seat 4 and the lower mold seat 908 are closed, rigid collisions between components can be avoided.
