Description

Technical Field

[0001] This utility model relates to the field of die casting molds, specifically to a V-tooth inlay structure for a heat dissipation tooth die casting mold. Background Technology

[0002] In recent years, with the continuous development of communications, the requirements for communication products have become increasingly stringent. The effective operation of communication devices relies on heat dissipation. For example, the heat sinks in communication devices are becoming increasingly tall and thin. Existing communication devices can have their heat sink fins die-cast together, requiring the creation of cavities with heat dissipation teeth in the die-casting mold. Due to the height and thinness of these heat dissipation teeth, conventional machining methods are insufficient, especially for V-tooth structure heat sink fins. These can only be machined using integral electrical discharge machining (EDM) with blade electrodes. This machining method has a long processing cycle, high manufacturing costs, and the surface finish of the EDM cavity is not high, making polishing difficult. Summary of the Invention

[0003] To address the shortcomings of the existing technology, this utility model provides a V-tooth inlay structure for a heat dissipation tooth die-casting mold, which is simple to process, easy to assemble, and has good structural stability.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A V-tooth insert structure for a heat dissipation tooth die-casting mold, characterized in that it includes a mold core, an insert pressure plate, and inserts, wherein the mold core has an insert placement cavity in the middle, and there are multiple inserts arranged in the insert placement cavity according to a predetermined rule, wherein the inserts located in the left half of the insert placement cavity are arranged inclined to the lower right, and the inserts located in the right half of the insert placement cavity are arranged inclined to the lower left, and a heat dissipation tooth forming cavity is formed between the contact edges of any two inserts along the inclined direction, the back of the mold core has a first recessed platform supporting the outer end of the insert, and the back of the mold core has a second recessed platform for mounting the insert pressure plate, the insert pressure plate is fastened to the second recessed platform by screws, and the cantilever end of the insert is fastened to the middle part of the insert pressure plate by screws.

[0006] Furthermore, the insert placement cavity is provided with a lower left corner block, a lower right corner block, and a V-shaped corner block, and the contact surfaces of the lower left corner block, the lower right corner block, and the V-shaped corner block with the insert have heat dissipation tooth-shaped cavities.

[0007] Furthermore, the multiple inserts are connected and positioned by locating pins.

[0008] Furthermore, the side of the mold core is provided with locking screws for connecting the insert.

[0009] The beneficial effects of this utility model include: the use of an inlay structure to form a V-shaped tooth cavity reduces the processing difficulty, shortens the processing cycle, results in high cavity surface quality, reduces polishing and grinding processes, lowers manufacturing costs, and provides high structural stability after assembly, which helps to ensure continuous and stable production.

[0011] Figure 2 This is a schematic diagram of the mold core structure of this utility model. Detailed Implementation

[0012] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0013] One such Figures 1-2 The V-tooth insert structure of the heat dissipation tooth die-casting mold shown includes a mold core 1, insert pressure plate 2, and inserts 3. The mold core 1 has an insert placement cavity in the center. Multiple inserts 3 are arranged in the insert placement cavity according to a predetermined rule. Inserts 3 located in the left half of the cavity are arranged at a downward-right inclination, while inserts 3 located in the right half are arranged at a downward-left inclination. The inserts 3 are disconnected at the symmetrical centerline of the cavity. A heat dissipation tooth forming cavity is formed between the contact edges of any two inserts 3 along the inclined direction. Therefore, inserts can be machined individually. This inserting method allows for the complete insertion of V-tooth blades.

[0014] like Figure 2 The back of the mold core 1 shown has a first recessed platform 11 supporting the outer end of the insert 3, and a second recessed platform 12 for mounting the insert pressure plate 2. The insert pressure plate 2 is fastened to the second recessed platform 12 by screws, and the cantilever end of the insert 3 is fastened to the middle of the insert pressure plate 3 by screws, thereby improving the installation stability of the insert 3.

[0015] like Figure 1 As shown, the insert placement cavity is equipped with a lower left corner block 4, a lower right corner block 5, and a V-shaped corner block 6. The contact surfaces of the lower left corner block 4, lower right corner block 5, and V-shaped corner block 6 with the insert 3 have heat dissipation toothed forming cavities. Multiple inserts 3 are connected and positioned by locating pins 7, thereby ensuring the positional accuracy of the holes. The side of the mold core 1 is equipped with locking screws 8 that connect the inserts 3; tightening the screws reduces the cumulative gap between the inserts.
