Description

Technical Field

[0001] The utility model belongs to the technical field of die casting die design, in particular to a die casting die. Background Art

[0002] A die-casting mold is a mold used in the metal die-casting process. Die-casting is an efficient and high-precision metal forming method widely used in industries such as automotive, aviation, electronics, and home appliances. The primary function of a die-casting mold is to inject molten metal (such as aluminum, zinc, magnesium, and copper) into the mold cavity under high pressure, where it cools and solidifies to form the desired part. Die-casting molds are an indispensable tool in modern industry, and their design and manufacturing directly impact product quality and production efficiency. With technological advancements, die-casting mold design and manufacturing processes are constantly being optimized to meet higher production requirements and more complex product demands.

[0003] After the die-casting mold is opened, the mold body needs to be cooled to facilitate demolding of the molded parts. The existing cooling device has a slow cooling speed and large energy loss. At the same time, the time for cooling the coolant during continuous production is short, and the coolant is easily not fully cooled, which affects the cooling effect and is not conducive to long-term operation of the device.

[0011] Furthermore: the connecting pipe is connected to the circulation box flange, and the infusion pump is connected to the cooling box with bolts.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The design of setting up a circulating pump to drive the heat transfer fluid to circulate along the U-shaped cooling pipe removes the heat from the bottom mold body, facilitates demoulding, and prevents the molded parts from sticking. At the same time, the design of the cooling pipe flowing directly along the mold can increase the heat exchange area, increase the cooling speed, and reduce energy loss.

[0014] 2. The design of setting up two cooling boxes to replenish the heat transfer fluid for the circulation box can prevent the heat transfer fluid from not being cooled down in time during the continuous processing process, which affects the heat absorption effect. The two sets of cooling boxes circulate and output the heat transfer fluid to ensure the cooling reliability. At the same time, it improves the stability of the continuous production of the device and is convenient for long-term use. BRIEF DESCRIPTION OF THE DRAWINGS
