Technical Field

[0001] This utility model relates to the field of automotive hardware processing technology, specifically to an automotive hardware die-casting mold with an improved structure. Background Technology

[0002] Die casting of hardware parts involves using high pressure to force molten metal into the cavity of a precision metal mold at high speed. The molten metal cools and solidifies under pressure to form a casting. However, existing automotive hardware die casting molds can only process a limited variety of hardware parts, and it is not convenient to disassemble and replace the lower and upper inner molds, making it difficult to adapt to die casting operations for hardware parts of different shapes.

[0003] To address the aforementioned problems, an improved die-casting mold for automotive hardware parts is proposed here. Utility Model Content

The end of each of the four connecting ropes away from the limiting block passes through the fixing block and is fixedly connected to the two ends of the two connecting strips respectively. By pulling the two connecting strips, the four connecting ropes are moved, thereby retracting the four limiting blocks into the four mounting slots respectively, so that they are separated from the four limiting slots.

[0008] Preferably, each of the four fixing blocks has a through hole in the middle, and the four through holes are respectively set to correspond to the four connecting ropes. The through holes facilitate the stable movement of the connecting ropes.

[0009] Preferably, two connecting slots are provided at the connection between the first mounting slot and the lower inner mold and at the connection between the second mounting slot and the upper inner mold. Connecting blocks are engaged inside the four connecting slots. The four connecting blocks are fixedly connected to the lower inner mold and the upper inner mold respectively. The four connecting blocks are engaged with the four connecting slots to facilitate the initial positioning of the lower inner mold and the upper inner mold.

[0010] Preferably, positioning posts are fixedly provided at the four corners of the bottom of the upper mold base, and positioning holes are provided at the four corners of the top of the lower mold base. The four positioning holes are respectively provided corresponding to the four positioning posts. The cooperation between the four positioning holes and the four positioning posts facilitates the precise docking of the lower mold base and the upper mold base.

[0011] Preferably, a second forming groove is provided in the middle of the bottom end of the upper inner mold, and a first forming groove is provided in the top end of the lower inner mold. The first forming groove and the second forming groove are correspondingly arranged, and the cooperation between the first forming groove and the second forming groove facilitates the die casting of automotive hardware parts.

[0012] Preferably, a guide pipe is fixedly provided at the connection between the fixed plate and the upper mold base. The top end of the guide pipe extends to the outside and is fixedly connected to the inlet. A through groove is opened at the top end of the upper inner mold. The through groove is correspondingly provided with the guide pipe. The through groove facilitates the connection of the guide pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The four connecting blocks engage with the four connecting slots to initially limit the lower and upper inner molds. The four limiting blocks, under the action of several telescopic springs, engage with the four limiting slots to further limit and fix the lower and upper inner molds. Pulling the two connecting strips moves the four connecting ropes, causing the four limiting blocks to retract into the four mounting slots, separating them from the four limiting slots. Then, using a larger force to pull the lower and upper inner molds facilitates quick disassembly and replacement, thus adapting to the die-casting operations of different shaped hardware parts.
