Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of molds, and in particular to a precision mold for producing ultra-thin bezels for classroom monitors. Background Technology
[0002] Traditional extrusion dies are typically single-cavity, resulting in low production efficiency. Therefore, some dies employ a dual-cavity or multi-cavity design. When using a dual-cavity extrusion die to produce... Figure 1 When the ultra-thin bezel profile 10 of a classroom monitor is shown, the difference in wall thickness between the two sides of the profile, with the right side being thicker than the left, will cause the profile produced by the double-cavity mold to be bent and twisted, resulting in the two profiles being of different lengths. Utility Model Content
[0003] The purpose of this invention is to provide a precision mold for producing ultra-thin bezels for classroom monitors, which improves production efficiency and ensures uniform profile length.
[0004] To achieve the above objectives, the solution of this utility model is:
[0005] A precision mold for producing ultra-thin bezels for classroom monitors includes a mold body, a top surface of the mold body with two welding chambers arranged side by side, each welding chamber having a forming hole, and a bottom surface of the mold body with two discharge chambers arranged side by side, each corresponding to and connected to the forming hole.
[0006] The outline of the forming hole corresponds to the outline of the ultra-thin bezel of the classroom monitor. The two forming holes are symmetrically arranged on the left and right, and the side holes on the side where the two forming holes are far apart from each other are used to form the thicker side wall of the ultra-thin bezel of the classroom monitor.
[0007] A flow-blocking block is provided between the side hole of the forming hole and the side wall of the welding chamber;
[0008] The ultra-thin bezel of the classroom display is an open profile, and the discharge cavity has a reinforcing block connected to one side of the opening of the open profile corresponding to the forming hole.
[0009] Furthermore, one side wall of the flow-blocking block is connected to the side wall of the welding chamber, and the other side wall is flush with the side hole wall.
[0010] Furthermore, the flow-blocking block has arc-shaped chamfers on both the front and rear sides of its sidewall near the side hole.
[0011] Furthermore, one end of the reinforcing block extends into the position corresponding to the opening of the profile in the forming hole, and the other end is connected to the side wall of the discharge cavity.
[0012] Furthermore, the sidewall of the discharge chamber has arc-shaped concave walls on both sides of the reinforcing block, and the arc-shaped concave walls are smoothly connected to the sidewall of the reinforcing block.
[0013] By adopting the above technical solution, two flow-blocking blocks can balance the metal flow velocity on both sides of each forming hole, thereby reducing the metal flow velocity at the side holes. This prevents the profile formed by the final forming hole from bending or twisting, ensuring that the profiles formed by the two forming holes have the same length, which facilitates production. Furthermore, a reinforcing block can be installed in the discharge cavity. This reinforcing block is connected to one side of the opening of the profile corresponding to the forming hole, that is, to the root of the die head forming that hole. This can improve the impact resistance of the die head, prevent die head damage, and extend the service life of the die. Attached Figure Description

Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0020] like Figures 2 to 4 As shown, this embodiment of a precision mold for producing ultra-thin bezels for classroom displays includes a mold body 1. The top surface of the mold body 1 has two welding chambers 11 arranged side by side, and each welding chamber 11 has a forming hole 12. The bottom surface of the mold body 1 has two discharge chambers 13 arranged side by side, which are respectively connected to the forming holes 12.
[0021] The contour of the forming hole 12 corresponds to Figure 1The outline of the ultra-thin bezel of the classroom monitor shown has two molding holes 12 symmetrically arranged on the left and right, and the side hole 121 on the side where the two molding holes 12 are far apart from each other is used to form the thicker side wall of the ultra-thin bezel of the classroom monitor; that is, the width of the side hole 121 is wider.
[0022] A flow-blocking block 14 is provided between the side hole 121 of the forming hole 12 and the side wall of the welding chamber 11;
[0023] The ultra-thin bezel of the classroom display is an open profile, and the discharge cavity 13 has a reinforcing block 15, which is connected to one side of the opening of the opening profile corresponding to the forming hole 12.
[0024] Therefore, this embodiment has two welding chambers 11 and two forming holes 12, which can form two profiles at once, thereby improving production efficiency. Since the two welding chambers 11 are spaced apart from each other, and the side holes 121 of the two forming holes 12 that are far apart from each other are set to be wider holes, that is, the side hole 121 on the left side of the left forming hole 12 is wider, and the side hole 121 on the right side of the right forming hole 12 is wider, and since the metal material in the middle position needs to be distributed to the two welding chambers 11 during the same aluminum rod extrusion process, the metal material on the side of the two forming holes 12 that is close to each other will be less than the side that is far apart from each other. Therefore, in order to avoid the metal material in the two side holes 121 that are far apart from each other and the metal flow rate is too fast, two flow blocking blocks 14 are set to balance the metal flow rate on the left and right sides of each forming hole 12, thereby reducing the metal flow rate at the side hole 121, so that the profile formed by the final forming hole 12 will not be bent or twisted, and the profile formed by the two forming holes 12 will have the same length, which facilitates production.
[0025] A reinforcing block 15 can be provided in the discharge cavity 13. The reinforcing block 15 is connected to one side of the opening of the profile corresponding to the forming hole 12, that is, connected to the root of the die head 122 that forms the forming hole 12. This can improve the impact resistance of the die head 122, prevent damage to the die head 122, and increase the service life of the mold.
[0026] In this embodiment, one sidewall of the flow-blocking block 14 is connected to the sidewall of the welding chamber 11, and the other sidewall is flush with the wall of the side hole 121 to improve the flow-blocking effect. The front and rear sides of the sidewall of the flow-blocking block 14 near the side hole 121 are provided with arc-shaped chamfers 141 to facilitate metal flow.
[0027] In this embodiment, one end of the reinforcing block 15 extends into the opening of the forming hole 12 corresponding to the opening of the profile, and the other end is connected to the side wall of the discharge cavity 13. The side wall of the discharge cavity 13 has arc-shaped concave walls 131 on both sides of the reinforcing block 15, and the arc-shaped concave walls 131 are smoothly connected to the side wall of the reinforcing block 15. This can enhance the strength of the reinforcing block 15 itself.
