Description

Technical Field

[0001] This utility model relates to the field of polymer mold technology, and more specifically, to hot-pressing polymer molds. Background Technology

[0002] In the polymer material processing industry, thermoforming is a widely used molding process. By applying a certain temperature and pressure to polymer materials, they undergo plastic deformation in a mold to obtain products of a specific shape.

[0003] During the hot pressing process, traditional molds are subject to high temperature and pressure, which can easily cause displacement and deformation of various components. This results in low dimensional accuracy and unstable quality of the molded polymer products. For example, in some molds for producing mobile phone casings, due to insufficient structural stability, the hot-pressed mobile phone casings have dimensional deviations and cannot be perfectly matched with other parts, resulting in a high defect rate. The hot pressing process generates a lot of heat, and many traditional molds lack effective heat dissipation structures and can only rely on natural heat dissipation. This not only leads to low production efficiency but also affects the molding quality of polymer materials. Therefore, a hot pressing molding polymer mold is proposed. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a hot-pressed polymer mold to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hot-pressing polymer mold, comprising a base plate, wherein long columns and short columns are symmetrically arranged around the top perimeter of the base plate, and the long columns and short columns can form a stamping mold groove around the top perimeter of the base plate; a first positioning groove and a mold cavity are provided on the surface of the base plate; and first mounting holes are symmetrically provided around the perimeter of the base plate; the mold groove formed by the long columns and short columns corresponds to the mold cavity and is used to accommodate polymer material, so that it is formed into the desired shape during the hot pressing process;

[0006] The long column includes a first positioning plate and two first stabilizing support plates fixed to one side of the first positioning plate. Multiple first heat dissipation plates are fixedly connected between the two first stabilizing support plates. The heat dissipation plates can quickly dissipate the heat generated during the hot pressing process, effectively reducing the mold temperature, improving heat dissipation performance, and ensuring the molding quality of the polymer material. At the same time, the two first stabilizing support plates can withstand high temperature and high pressure during the hot pressing process without deformation or displacement. The first positioning plate has a second positioning slot and a positioning hole at both ends of one side. The second positioning slot facilitates the positioning of the first positioning plate and the second positioning plate, making it easy to combine and use. The positioning hole facilitates the combination and fixing of the long column and the short column together, enhancing the stability and positioning accuracy of the overall mold structure.

[0007] The short column includes a second positioning plate and two second stabilizing support plates fixed to one side of the second positioning plate. The two second stabilizing support plates can support and reinforce the second positioning plate, enhancing the structural stability of the short column. Multiple second heat dissipation plates are fixedly connected between the two second stabilizing support plates, which further improve the heat dissipation capacity of the mold. The surface of the second heat dissipation plates is provided with fixing holes, which can be used to easily fix the long column and the short column together through the positioning holes, ensuring the structural stability of the mold during the hot pressing process.

[0008] Preferably, the mold cavity is located at the center of the surface of the base plate, and the first positioning slot is located around the mold cavity. The size of the first positioning slot is adapted to the first positioning plate and the second positioning plate to facilitate combination and positioning.

[0009] Preferably, the bottom ends of the first positioning slot and the second positioning plate both extend into the interior of the first positioning slot, and the two ends of the second positioning plate correspond to the second positioning slot. The two ends of the second positioning plate respectively extend into the interior of the second positioning slot at one end of the two first positioning plates, which facilitates the positioning of the long column and the short column during installation and improves the accuracy and stability of the assembly.

[0010] Preferably, the surfaces of the first and second stabilizing support plates at the bottom are provided with second mounting holes at positions corresponding to the first mounting holes. Bolts are inserted into the middle of both the second and first mounting holes. By cooperating with the second and first mounting holes, the long and short columns can be fixed to the base plate, thereby improving the overall stability.

[0011] Preferably, the positioning hole corresponds to the fixing hole, and a long screw is inserted into the middle of both the first positioning plate and the fixing hole to facilitate tight assembly and fixing of the short column.

[0012] Preferably, the height of the second positioning plate is the same as the height of the first positioning plate, and the lengths of the first heat sink and the second heat sink are the same as the widths of the first stabilizing support plate and the second stabilizing support plate, respectively, so that the heat sink can fully cover the space between the support plates, maximize the heat dissipation area, and improve the heat dissipation efficiency.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model uses a mold groove composed of long and short columns that corresponds to the mold cavity to accommodate polymer materials, allowing them to be molded into the desired shape during hot pressing. The first and second heat dissipation plates can quickly dissipate the heat generated during hot pressing, effectively reducing the mold temperature, improving heat dissipation performance, ensuring the molding quality of the polymer materials, and improving processing efficiency. At the same time, the two second stabilizing support plates and the two first stabilizing support plates can provide support and reinforcement, enhancing the structural stability of the short and long columns. The second positioning slots and positioning holes facilitate the combination and fixing of the long and short columns together, enhancing the overall stability and positioning accuracy of the mold structure.

[0015] 2. This utility model also features a second positioning plate and a first positioning plate, both of which are inserted into the first positioning slot. This allows for the positioning of the long and short columns during installation. The second positioning slot improves the precision of the positioning between the long and short columns. The long screw passes through the middle of the positioning hole and the fixing hole, enhancing the connection stability of the long and short columns. The cooperation between the second mounting hole and the first mounting hole allows the long and short columns to be fixed in place, improving the overall strength of the assembly and preventing displacement or deformation.

[0016] In summary, through the interaction of the above-mentioned multiple effects, the overall stability and positioning accuracy of the mold structure can be enhanced, displacement and deformation can be avoided, the mold temperature can be effectively reduced, heat dissipation performance can be improved, the molding quality of polymer materials can be guaranteed, and processing efficiency can be improved.

[0023] 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.

[0024] As attached Figure 1-5 The hot-pressing polymer mold shown includes a base plate 1. Long columns 2 and short columns 3 are symmetrically arranged around the top of the base plate 1. The long columns 2 and short columns 3 can form a stamping mold groove around the top of the base plate 1. A first positioning slot 5 and a mold cavity 11 are opened on the surface of the base plate 1. First mounting holes 4 are symmetrically opened around the bottom of the base plate 1. The mold groove formed by the long columns 2 and short columns 3 corresponds to the mold cavity 11 and is used to accommodate polymer materials so that they are formed into the required shape during the hot pressing process.

[0025] The long column 2 includes a first positioning plate 6 and two first stabilizing support plates 7 fixed to one side of the first positioning plate 6. Multiple first heat dissipation plates 10 are fixedly connected between the two first stabilizing support plates 7. The heat dissipation plates 10 can quickly dissipate the heat generated during the hot pressing process, effectively reduce the mold temperature, improve heat dissipation performance, and ensure the molding quality of the polymer material. At the same time, the two first stabilizing support plates 7 can withstand high temperature and high pressure during the hot pressing process without deformation or displacement. The first positioning plate 6 has a second positioning slot 8 and a positioning hole 9 at both ends of one side. The second positioning slot 8 can be used to easily position the first positioning plate 6 and the second positioning plate 12 for easy combination. The positioning hole 9 can be used to easily combine and fix the long column 2 and the short column 3 together, enhancing the stability and positioning accuracy of the overall mold structure.

[0026] The short column 3 includes a second positioning plate 12 and two second stabilizing support plates 13 fixed to one side of the second positioning plate 12. The two second stabilizing support plates 13 can support and reinforce the second positioning plate 12, thereby enhancing the structural stability of the short column 3. Multiple second heat dissipation plates 14 are fixedly connected between the two second stabilizing support plates 13, thereby further improving the heat dissipation capacity of the mold. Fixing holes 16 are provided on the surface of the second heat dissipation plates 14. The fixing holes 16 can be used to easily fix the long column 2 and the short column 3 together through the positioning holes 9, ensuring the structural stability of the mold during the hot pressing process.

[0027] As attached Figure 1-5 As shown, the mold cavity 11 is located at the center of the surface of the base plate 1. The first positioning slot 5 is located around the mold cavity 11. The size of the first positioning slot 5 is adapted to the first positioning plate 6 and the second positioning plate 12. The bottom ends of the first positioning slot 5 and the second positioning plate 12 extend into the interior of the first positioning slot 5. The two ends of the second positioning plate 12 correspond to the second positioning slot 8. The two ends of the second positioning plate 12 extend into the interior of the second positioning slot 8 at one end of the two first positioning plates 6. The surfaces of the bottom first stabilizing support plate 7 and the second stabilizing support plate 13 are provided with second mounting holes 15 at positions corresponding to the first mounting holes 4. Bolts are inserted into the middle of the second mounting holes 15 and the first mounting holes 4. The positioning hole 9 corresponds to the fixing hole 16. Long screws are inserted into the middle of the first positioning plate 6 and the fixing hole 16. The height of the second positioning plate 12 is the same as the height of the first positioning plate 6. The lengths of the first heat dissipation plate 10 and the second heat dissipation plate 14 are the same as the widths of the first stable support plate 7 and the second stable support plate 13, respectively. This facilitates the positioning of the long column 2 and the short column 3, improving the accuracy and stability of the assembly. Through the cooperation of the second mounting hole 15 and the first mounting hole 4, the long column 2 and the short column 3 can be fixed on the base plate 1, improving the overall stability and facilitating the tight assembly and fixing of the long column 2 and the short column 3. This allows the heat dissipation plate to fully cover the space between the support plates, maximizing the heat dissipation area and improving the heat dissipation efficiency.

[0028] The working principle of this utility model is as follows: When in use, first align the first positioning plate 6 of the long column 2 with the first positioning slot 5 on the base plate 1 and slowly insert it so that the bottom wall of the first positioning plate 6 is completely embedded in the first positioning slot 5, ensuring the accurate positioning of the long column 2 on the base plate 1. At this time, the second mounting hole 15 at the bottom of the first stable support plate 7 is aligned with the first mounting hole 4 on the base plate 1.

[0029] Then, align the second positioning plate 12 of the short column 3 with the first positioning slot 5 on the side of the base plate 1, and make the two ends of the second positioning plate 12 correspond to the second positioning slot 8. Then slowly insert it to achieve precise cooperation between the short column 3 and the long column 2. At this time, the second mounting hole 15 at the bottom of the second stable support plate 13 is also aligned with the first mounting hole 4 on the base plate 1.

[0030] Then, the bolts are passed through the second mounting hole 15 and the first mounting hole 4 in sequence and tightened to firmly assemble the long column 2, the short column 3 and the base plate 1 together. The long screw is then passed through the positioning hole 9 and the fixing hole 16 in sequence and tightened to further enhance the connection between the long column 2 and the short column 3, thus completing the assembly of the mold.

[0031] During hot pressing, the mold is placed on the hot pressing device, and the polymer material needs to be placed in the mold cavity 11. During hot pressing, the heat around the base plate 1 can be quickly dissipated through the first heat dissipation plate 10 and the second heat dissipation plate 14 to achieve the cooling effect.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
