Die-casting mould for tubular automobile part

Abstract

The invention provides a die-casting mould for a tubular automobile part. The die-casting mould comprises a pouring system, a cooling system and a preheating system. The pouring system comprises a lower mould body, an upper mould body, a hole core, a hydraulic cylinder, a piston rod, a rubber push head, a mould release agent cavity, an agent inlet pipe, a core pulling device, a cavity, a branch pouring gate, sprue gates and a main pouring gate. The cavity is defined by the upper mould body and the lower mould body. The sprue gates are formed in the top end of the upper mould body. The hydraulic cylinder is arranged in the lower mould body. The piston rod is arranged on the left side of the hydraulic cylinder. The cooling system comprises a water inlet, a cooling water pipeline, a water outlet and a heat preservation water tank. The preheating system is composed of preheating hole channels and heating pipes. By means of the mould release agent cavity, a mould release agent can be sprayed to the cavity, and the part is not likely to deform in the mould release process. By means of the heating pipes and the preheating hole channels, the die-casting mould can be effectively preheated, heat fatigue cracks of the die-casting mould are avoided, and the service life of the die-casting mould is prolonged. By means of the heat preservation water tank, cooling water can be recycled and used for other devices, and waste is avoided.

Description

technical field [0001] The invention relates to a die-casting mold for tubular automobile parts, which belongs to the field of mold equipment. Background technique [0002] Mold: various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping, stretching and other methods to obtain the required products. In short, a mold is a tool used to shape an object. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. Die-casting mold is a method of casting liquid die forging, a process completed on a special die-casting die forging machine. When die-casting automotive tubular parts, the die-casting mold uses molten metal to pour into the cavity, and it can be formed after cooling, because the temperature of the molten metal is very...

Problems solved by technology

When die-casting automotive tubular parts, the die-casting mold uses molten metal to pour into the cavity, and it can be formed after cooling, because the temperature of the molten metal is very high, but the forming of the parts needs to be cooled, such alternating heat and cold will make The die-casting mold produces thermal fatigue, which leads to the appearance of cracks, which leads to the scrapping of the die-casting mold. At the same time, the die-casting mold is not very easy to remove from the mold and often sticks. However, if the force is too strong, it will easily cause the parts to deform, so a tube-shaped auto part is needed Die-casting mold to solve the above problems
