Description

Technical Field

[0001] This utility model relates to a stamping die holder, specifically a stamping die holder for a television back panel. Background Technology

[0002] The mold base is an important component of the TV back panel stamping mold. Its main function is to support and fix other parts of the stamping mold, such as the mold core, slider, ejector pin, etc., and to ensure that they maintain the correct position and stability during injection molding or other molding processes.

[0003] Existing TV back panel stamping mold bases have a complex structure and unreasonable design. The bottom mold plate and the forming table on the stamping mold base are basically fixed as one piece and cannot be separated. Therefore, a single stamping mold base can only stamp a TV back panel of a specific shape, which limits its applicability. Secondly, the top and bottom mold plates on the stamping mold base are usually set in parallel, and they work together to complete the stamping of the TV back panel. However, during the stamping process, the pressure of the top mold plate is entirely applied to the bottom mold plate, and the pressure source is usually concentrated at the center of the top mold plate, while the pressure at the edges is smaller. Therefore, the pressure distribution is uneven, which easily leads to cracking or deformation after stamping. To address these issues, the inventors have improved the structure of the TV back panel stamping mold base. Utility Model Content

[0004] The purpose of this utility model is to provide a TV back panel stamping die base, which has a simple structure, reasonable design, and can easily disassemble and replace the forming table, facilitating quick switching between different forming tables to stamp TV back panels of different shapes. This increases the applicability of the stamping die base, makes the pressure more evenly distributed on the bottom template, ensures that the pressure is balanced throughout the bottom template, and reduces the probability of cracking or deformation during stamping. This solves the problems mentioned in the above-mentioned technical background.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a stamping die base for a television back panel, the stamping die base including a top die plate and a shaping platform and a bottom die plate disposed below the top die plate, wherein the shaping platform is located between the top die plate and the bottom die plate;

[0006] The top formwork includes a top plate body, with a protrusion on the outer side of the top plate body and a concave cavity on the lower end face of the top plate body, and an arc-shaped inner wall inside the protrusion.

[0007] The forming platform includes a main platform body, on which a die-casting template is fixed;

[0008] The bottom template includes a base plate body and a pressure-bearing platform set below the base plate body. The base plate body is provided with an adaptable outer wall, and the upper end face of the base plate body is provided with multiple mounting grooves. The main platform body fits into the multiple adaptable outer walls. The adaptable outer walls are adapted to the arc-shaped inner walls, that is, the position of the protrusion on the arc-shaped inner wall is exactly set at the position of the adaptable outer wall.

[0009] Preferably, a die-casting groove is provided in the concave cavity, and a die-casting template is provided in the die-casting groove. During stamping, the plate to be stamped is placed between the top plate body and the main platform body, and the plate to be stamped is stamped into a specified shape by the action of the top plate body and the main platform body.

[0010] Preferably, the main body is provided with multiple inclined outer walls, and multiple mounting slots are provided with inclined inner walls.

[0011] Preferably, multiple inclined outer walls are respectively attached to multiple inclined inner walls, and the inclination angles of the inclined outer walls and inclined inner walls are all between 1° and 3°, so that the main platform can be smoothly attached to the base plate body, and the main platform can be removed from the base plate body without tools, realizing the quick assembly and disassembly of the main platform.

[0012] Preferably, a fixing groove is provided on the lower end face of the base plate body, and the pressure-bearing platform fits into the fixing groove.

[0013] Preferably, the bottom of the pressure-bearing platform is equipped with multiple stabilizing bolts, which pass through the pressure-bearing platform from bottom to top and into the base plate body, so that the pressure-bearing platform can be smoothly installed at the bottom of the base plate body, wherein the pressure-bearing platform plays the role of bearing the pressure on the base plate body.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model provides a stamping die base for a television back panel. The stamping die base includes a top die plate, a shaping platform, and a bottom die plate located below the top die plate. The overall structure is simple and rationally designed. The shaping platform includes a main body with multiple inclined outer walls. The bottom die plate includes a base plate and a pressure plate located below the base plate. The upper surface of the base plate has multiple mounting grooves, each with an inclined inner wall. The multiple inclined outer walls respectively fit into the multiple inclined inner walls, allowing the main body to be snapped into the mounting grooves. That is, the shaping platform and the bottom die plate are snapped together and fixed. The snapping is completed by adapting the multiple inclined outer walls on the main body to the inclined inner walls of the mounting grooves on the base plate. The shaping platform can be easily disassembled and replaced, facilitating quick switching between different shaping platforms and making the replacement of the shaping platform more convenient and efficient. This allows for the stamping of television back panels of different shapes and increases the applicability of the stamping die base, making it suitable for widespread use.

[0016] The top template of this utility model includes a top plate body with a protrusion on the outer side of the top plate body and an arc-shaped inner wall inside the protrusion. The bottom plate body has an adaptable outer wall that matches the arc-shaped inner wall. That is, the position of the arc-shaped inner wall on the protrusion is exactly at the position of the adaptable outer wall. When the top template approaches the bottom template, the position of the arc-shaped inner wall on the protrusion presses against the position of the adaptable outer wall, making the top template and the bottom template perfectly matched. Furthermore, since the top of the bottom template is punched into the interior of the concave cavity, the pressure can be distributed more evenly on the bottom template, thereby ensuring that the pressure is balanced throughout the bottom template and reducing the probability of cracking or deformation during stamping. It is highly practical. Attached Figure Description

Multiple mounting grooves 312 are provided on the upper end surface of the base plate body 31.

[0029] Please see Figure 5 The main platform 21 is provided with multiple inclined outer walls 211, and multiple mounting slots 312 are each provided with an inclined inner wall 3121. The multiple inclined outer walls 211 are respectively attached to the multiple inclined inner walls 3121, and the inclination angle between the inclined outer walls 211 and the inclined inner walls 3121 is between 1° and 3°, so that the main platform 21 can be smoothly snapped onto the base plate 31. At the same time, the main platform 21 can be removed from the base plate 31 without tools, realizing the quick assembly and disassembly of the main platform 21, thereby facilitating the quick switching between different main platforms 21. This makes the replacement of the main body 21 more convenient and efficient, so as to stamp out TV back panels of different shapes, thus increasing the scope of application. The lower end face of the base plate 31 is provided with a fixing groove 313. The pressure plate 32 fits into the fixing groove 313. Multiple stabilizing bolts 33 are installed at the bottom of the pressure plate 32. The multiple stabilizing bolts 33 pass through the pressure plate 32 from bottom to top and enter the base plate 31, so that the pressure plate 32 can be smoothly installed at the bottom of the base plate 31. The pressure plate 32 plays the role of bearing the pressure on the base plate 31.
