Description

[Technical Field]

[0001] This invention relates to the field of die casting technology, and in particular to a method for forming a die casting part with heat dissipation fins and the product formed therefrom. [Background Technology]

[0002] Conventional die-cast parts and heat sinks are integrally formed within the die-casting mold, such as... Figure 1 As shown, the heat sink 20 is tall, thin, and has zero draft, which makes it difficult to form the die-cast part, prone to air entrapment, and easy to stick to the film.

[0003] In view of this, it is necessary to provide a method for forming a die-cast part with heat dissipation fins and the product formed therefrom to solve the above problems. [Summary of the Invention]

[0004] The technical problem this invention aims to solve is that conventional die-casting parts and heat sinks are integrally formed within a die-casting mold. However, traditional heat sinks are tall, thin, and have zero draft, leading to difficulties in die-casting, air trapping, and mold sticking. Therefore, this invention provides a method for forming a die-casting part with heat sink fins and the resulting product to solve the above problems.

[0005] The solution to the technical problem of this invention is: a method for forming a die-cast part with heat dissipation fins, comprising:

[0006] S1, disassemble the heat dissipation fin part in the die casting and design the mold core to reserve the injection position of the heat dissipation fin part;

[0007] S2, the heat dissipation fins are CNC machined and then embedded into the mold cavity;

[0008] S3, The die-casting material is heated to a molten state and then added to the die-casting machine;

[0009] S4, injects the molten material from the die-casting machine into the mold cavity under high pressure;

[0010] S5. After the die casting has cooled and solidified, remove the die casting from the mold cavity.

[0011] S6 involves removing excess material, grinding, and painting the die-cast parts to obtain the final die-cast product.

[0012] Preferably, the die-casting material includes, but is not limited to, being heated to a molten state using an electric furnace or a gas furnace.

[0013] Preferably, when removing the die-cast part from the mold cavity, demolding includes, but is not limited to, using vibration or impact.

[0014] In addition, the present invention also provides a die-cast product with heat dissipation fins, which is a product formed by the above method.

[0015] The beneficial effects of this invention are as follows: This invention provides a method for forming a die-cast part with heat dissipation fins and the resulting product. The heat dissipation fin portion of the die-cast part is separated, and the mold core is designed to reserve embedding positions for the heat dissipation fins. The heat dissipation fins are CNC machined and then embedded into the mold cavity. The die-casting material is heated to a molten state and added to the die-casting machine. The molten material in the die-casting machine is injected into the mold cavity under high pressure. After the die-cast part cools and solidifies, it is removed from the mold cavity. The die-cast part undergoes finishing processes such as material removal, grinding, and painting to obtain the final die-cast product. This method, which embeds the heat dissipation fins into the mold cavity and then performs die casting to form an integrated structure, solves the problems of air pocketing, film adhesion, and poor filling caused by the height and thickness of the heat dissipation fins in the die-cast product. Furthermore, the height and thickness of the heat dissipation fins can be adjusted according to requirements. [Attached Image Description]
