Description

Technical Field

[0001] The utility model relates to the technical field of die casting moulds, in particular to a die casting mould for automobile parts. Background Art

[0002] Die casting is a metal casting process characterized by the use of high pressure to apply molten metal to the mold cavity. The mold is usually made of a stronger alloy and the process is somewhat similar to injection molding. Most die castings are non-ferrous, such as zinc, copper, aluminum, magnesium, lead, tin, lead-tin alloys and their alloys. Depending on the type of die casting, a cold chamber die casting machine or a hot chamber die casting machine is required.

[0003] At present, the guidance of most die-casting molds for auto parts on the market is not very good and the precision is not high, which can easily affect the quality of auto parts production, increase the production cost of auto parts production, and bring certain troubles to people's manufacturing.

[0004] After searching the existing Chinese patents: a die-casting mold for automobile parts (Announcement No.: CN217798893U), including a fixed platform, the bottom end of which is fixedly connected with a support leg. The die-casting mold for automobile parts is provided with a guide groove, a propulsion cylinder, a hydraulic push rod and a connecting plate to achieve the purpose of the die-casting mold having a good guiding effect. The molten metal is injected into the first mold, the hydraulic push rod is started, the position of the connecting plate and the second mold is driven to drop, and then the propulsion cylinder is driven to drop into the guide groove. At the same time, the collar on the outer wall of the propulsion cylinder moves up on the outer wall of the propulsion cylinder, driving the expansion and contraction of the second spring, so that the first spring is squeezed, driving the propulsion rod to drop, and when the bottom end of the propulsion rod drops into the guide groove, the first mold and the second mold are fitted, which not only improves the guiding performance between the first mold and the second mold, but also improves the quality of automobile parts production, saving a certain production cost for people's automobile parts production.

[0005] Although the above patent provides a cooling assembly, which is beneficial to the molding and cooling of the die-cast automobile parts inside the first mold, reduces the cooling time of the automobile parts, and improves the production efficiency of the automobile parts, it has the disadvantage that the first mold and the second mold of the device are respectively fixedly connected to the top of the fixing table and the bottom of the connecting plate. In this way, when the different first molds and the second molds need to be replaced, a new mold fixing device can only be remade, which increases the manufacturing cost.

[0006] Therefore, it is necessary to invent a die-casting mold for automobile parts to solve the above problems. Utility Model Content
