Technical Field

[0001] This utility model relates to the field of cable head die casting technology, specifically a cable head die casting machine equipped with a positioning and fixing mechanism. Background Technology

[0002] A cable head is an accessory used to connect, operate, or lock cables, enabling the cable to extend, fix, or guide its path. It is widely used in clothing, bags, outdoor equipment, automotive parts, and other fields. Cable heads are usually formed by die casting, in which molten metal is injected under high pressure into a mold cavity through a die casting machine and cooled and solidified to obtain a joint component that connects to the wire rope.

Therefore, it can only achieve unidirectional positioning during mold closing, which can easily lead to horizontal offset or vertical loosening, reducing the cavity stability during die casting and thus affecting the production of cable heads.

[0012] Preferably, the limiting cavity is provided with a positioning and fixing structure, which uses a slidably installed positioning rod to limit and fix the limiting block.

[0013] By adopting the above technical solution, the positioning and fixing structure can be used to further limit and fix the limiting block.

The upper surface of the storage tank 9 is provided with an inlet pipe connected to the molten metal. The outer casing 10 is wrapped and fixed to the outer surface of the storage tank 9. The upper surface of the outer casing 10 is open. The outer casing 10 is fixedly installed on the upper surface of the base 1 by a bracket. A heating wire 11 is fixedly installed on the inner wall of the outer casing 10. The heating wire 11 is in contact with the outer surface of the storage tank 9.

The heating wire 11 inside the outer casing 10 is activated, and the heating wire 11 contacts the outer surface of the storage tank 9 to continuously heat the storage tank 9. This continuously keeps the molten metal warm during the die casting process, preventing solidification before the subsequent molten metal injection process and ensuring the quality of die casting.

[0024] The mounting groove 6 on the surface of the lower mold base 3 has a height equal to the sum of the heights of the lower mold 7 and the upper mold 8. The surface of the lower mold base 3 is provided with a positioning structure.

The positioning structure includes a limiting cavity 13, which is a square structure and is located inside the lower mold base 3. The upper surface of the limiting cavity 13 is connected to the limiting groove 14, which is a cuboid structure and penetrates the upper surface of the lower mold base 3. Two limiting grooves 14 are symmetrically arranged above the limiting cavity 13. The limiting cavity 13 and the two limiting grooves 14 are arranged in two sets symmetrically on the lower mold 7. The limiting groove 14 is engaged with the limiting block 15. The upper end of the limiting block 15 is fixedly installed on the lower surface of the upper mold base 5. A circular through hole is provided on the surface of the limiting block 15. like Figure 3 , Figure 4 , Figure 5 and Figure 7As shown, during the die casting of molten metal, the lower mold 7 and the upper mold 8 are first closed. A steel wire rope is placed in the arc groove on the surface of the lower mold base 3, so that one end of the steel wire rope is inserted into the interior of the lower mold 7. The electric push rod 4 is activated, and the electric push rod 4 pushes the lower mold base 3 to slide upward along the guide post 2. As the lower mold base 3 rises, the limiting block 15 on the lower surface of the upper mold base 5 is inserted into the limiting groove 14 on the surface of the lower mold base 3. The cuboid structure of the limiting block 15 and the limiting groove 14 engages to limit the horizontal displacement of the lower mold 7 and the upper mold 8, thus achieving initial positioning.

[0025] The limiting cavity 13 is equipped with a positioning and fixing structure. The positioning and fixing structure uses a slidably mounted positioning rod 17 to limit and fix the limiting block 15. The positioning and fixing structure includes a mounting block 16, which is fixedly mounted on the inner wall of the limiting cavity 13. The positioning rod 17 is provided on the side surface of the mounting block 16 and is slidably mounted on the inner wall of the limiting cavity 13. One end of the positioning rod 17 is aligned with a circular through hole on the surface of the limiting block 15, and an electromagnet 19 is fixedly mounted on the other end of the positioning rod 17. A magnetic block 18 is aligned with the electromagnet 19 and is fixedly mounted on the surface of the mounting block 16. The magnetic poles of the magnetic block 18 and the electromagnet 19 repel each other. The surface of the positioning rod 17 is fixed to one end of the spring 20, and the other end of the spring 20 is fixed to the surface of the mounting block 16. The upper surface of the lower mold base 3 is provided with an arc-shaped groove. The arc-shaped groove on the surface of the lower mold base 3 is aligned with the semi-circular notch on the side surface of the lower mold 7 and the upper mold 8. A sealing gasket 21 is provided in the arc-shaped groove on the surface of the lower mold base 3. The sealing gasket 21 has a semi-circular structure. Two sealing gaskets 21 are vertically arranged. The lower sealing gasket 21 is fixedly installed on the inner wall of the annular groove on the surface of the upper mold base 5, and the upper sealing gasket 21 is fixedly installed on the lower surface of the upper mold base 5. like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, after the limiting block 15 is fully inserted into the limiting groove 14, the electromagnet 19 inside the limiting cavity 13 is activated. The electromagnet 19 is energized and generates a repulsive force with the magnetic block 18, pushing the positioning rod 17 to slide along the inner wall of the limiting cavity 13 until one end of the positioning rod 17 is inserted into the circular through hole on the surface of the limiting block 15. At this time, the spring 20 on the surface of the positioning rod 17 is in a stretched state. Through the engagement of the positioning rod 17 with the circular through hole, the lower mold 7 and the upper mold 8 are prevented from shifting vertically. At the same time, as the lower mold base 3 and the upper mold 8 move together, the lower mold base 7 and the upper mold 8 move together. During the engagement process between the mold bases 5, the upper and lower sealing gaskets 21 adhere to the outer surface of the wire rope, sealing the gap between the wire rope and the device, completing the mold closing and positioning. The injection head on the lower surface of the liquid storage tank 9 is activated, and the injection head generates pressure to push the molten metal into the injection pipe 12. The molten metal flows along the injection pipe 12, passes through the upper mold base 5, and is injected into the complete cavity structure assembled by the upper mold 8 and the lower mold 7 until the cavity is filled with molten metal. The molten metal cools and solidifies in the cavity, thereby realizing the forming process of the cable head casting.

[0026] Working Principle: When using this cable-driven die-casting machine equipped with a positioning and fixing mechanism, molten metal is stored inside the storage tank 9. The heating wire 11 on the inner wall of the outer casing 10 is activated to continuously heat the storage tank 9 and prevent the molten metal from solidifying. The wire rope is placed into the arc-shaped groove of the lower mold base 3, so that one end of the wire rope is inserted into the lower mold 7. The electric push rod 4 is activated, and the electric push rod 4 drives the lower mold base 3 to slide upward along the guide post 2. The lower mold base 3 drives the lower mold 7 to move upward synchronously and close with the upper mold 8, thus... The limiting block 15 on the lower surface of the upper mold base 5 is inserted into the limiting groove 14 of the lower mold base 3 to limit horizontal displacement. After the limiting block 15 is engaged, the electromagnet 19 is activated. Through the repulsive force between the electromagnet 19 and the magnetic block 18, the positioning rod 17 is pushed into the circular through hole of the limiting block 15 to prevent the lower mold 7 and the upper mold 8 from vertically shifting. The injection head under the liquid storage tank 9 is activated, and the molten metal is injected into the cavity formed by the upper mold 8 and the lower mold 7 through the injection pipe 12. After cooling and solidification, the cable head die casting is completed, which increases the overall practicality.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
