DETAILED DESCRIPTION

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] like Figures 1-6 As shown, this utility model has the characteristics of improving product quality and reducing overall product cost. The following technical solution is provided: A die-casting mold for an adapter includes an upper mold base 1 and a lower mold base 2 arranged vertically opposite each other. An upper mold core 3 is embedded in the upper mold base 1, and a lower mold core 4 matching the upper mold core 3 is embedded in the lower mold base 2. Two adapter forming cavities 5 are formed between the upper mold core 3 and the lower mold core 4. A core-pulling structure 6 is installed on the left side between the upper mold base 1 and the lower mold base 2, and a gate structure 7 is provided on the right side between the upper mold base 1 and the lower mold base 2. The side gate allows molten metal to enter the adapter forming cavity 5 from one side of the mold and flow longitudinally along the adapter forming cavity 5, which helps the molten metal to evenly fill the entire cavity. The core-pulling structure 6 includes an installation... A slider 61 is located on one side of the upper mold core 3 and the lower mold core 4. A drive cylinder 62 is installed on the rear side of the slider 61. A first hole forming rod 63, which is inserted into the adapter forming mold cavity 5, is installed side by side on the front side of the slider 61. Sliding seats 64 are provided on the left and right sides of the slider 61, and the sliding seats 64 are connected to the lower mold base 2. Multiple marking rods 8 are vertically inserted on the upper mold core 3. A marking head 9 with marking marks is inserted into one end of the marking rod 8 near the adapter forming mold cavity 5. Several second hole forming rods 10, which are inserted into the adapter forming mold cavity 5, are arranged on the upper part of the lower mold core 4. The forming accuracy of the adapter hole is ensured by the core pulling structure 6 and the second hole forming rods 10.

[0022] Specifically, a mold foot 11 is installed on each side of the lower end of the lower mold base 2, and a top plate assembly 12 is provided between the two mold feet 11. The top plate assembly 12 is provided with multiple push rods 13 for inserting into the mold cavity 5 of the adapter. A lower template 14 is fixedly provided at the lower end of the two mold feet 11 for ejecting the adapter from the mold after die casting is completed.

[0023] In this embodiment, as Figure 5 As shown, a sleeve 15 is fitted on the second hole forming rod 10. The sleeve 15 slides with the second hole forming rod 10 to prevent the second hole forming rod 10 from bending. The sleeve 15 is connected to the top plate assembly 12.

[0024] In this embodiment, as Figure 4 As shown, the upper end face of the lower mold core 4 and the lower end face of the upper mold core 3 are symmetrically arranged with a main channel 16 that communicates with the forming cavity 5 of the adapter. The main channel 16 is connected to the gate structure 7.

[0025] In this embodiment, as Figure 3 As shown, guide pillar structures 17 are installed at the four corners of the upper end face of the lower mold base 2, which improves the guiding accuracy and stability of the mold.

[0026] In this embodiment, as Figure 3 and Figure 4 As shown, positioning bosses 18 are provided at the three corners of the upper end of the lower mold core 4, and positioning grooves 19 are provided at the lower end of the upper mold core 3, which correspond to the positioning bosses 18 one by one. The positioning bosses 18 and positioning grooves 19 realize the precise alignment of the upper and lower mold cores.

[0027] In this embodiment, as Figure 1 As shown, the entire mold is first installed on the die-casting machine. The molten metal enters the mold through the gate structure 7. The molten metal enters the adapter forming cavity 5 through the main channel 16. The molten metal expels the air in the adapter forming cavity 5, so that the molten metal can fill the adapter forming cavity 5. After the product is formed, the mold is opened. The upper mold base 1 and the lower mold base 2 are separated by the guide pillar structure 17. The mold is opened, and the driving cylinder 62 of the core pulling structure 6 drives the first hole forming rod 63 to retract. The top plate assembly 12 drives the ejector rod 13 and the insert 15 to eject the formed adapter, completing the demolding.

[0028] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0029] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.
