Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories molding, in particular to a molding die for automobile chassis steering accessories. Background Art

[0002] Die casting is a metal casting process characterized by the use of a mold cavity to apply high pressure to the molten metal. The mold is usually made of a stronger alloy and the process is somewhat similar to injection molding. Die casting is particularly suitable for manufacturing a large number of small and medium-sized castings, so die casting is the most widely used of various casting processes.

[0003] The steering part of the automobile chassis is a hollow cylindrical structure. The molten metal flows in from the middle position of one side and needs to flow around the whole body and then to the two ends. During the die-casting process, the molten metal will cool down over time. After the liquid temperature drops, the flow rate slows down, which may cause gaps or bubbles to appear at both ends of the automobile chassis steering parts, resulting in poor quality of the automobile chassis steering parts. Breakage problems may occur during use, affecting the normal use of the automobile chassis. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The first positioning column and the second positioning column are set to a hollow structure with a hot oil flow channel inside. When the molten metal flows into the cavity, the first positioning column and the second positioning column can transfer the heat of the hot oil to the cooled molten metal, so that the molten metal is heated and flows into place to avoid gaps or bubbles.

[0013] 2. A third hot oil flow channel is provided on the sprue sleeve. When the molten metal is poured into the sprue sleeve, it is continuously heated by the hot oil, which increases the flow rate of the molten metal, shortens the die-casting time, and improves the die-casting efficiency and quality.
