Vehicle brake disc casting die

Abstract

The invention discloses a vehicle brake disc casting die which comprises a casting base, a first die holder and a second die holder. The first die holder and the second die holder are arranged above the casting base; a supporting table is arranged at the middle part of the casting base; a rotary table is arranged at the upper end of the supporting table; a thread bushing is arranged at the left side of the casting base; the inside of the thread bushing is meshed with a strut; a handle is arranged at the left side of the strut; a clamping plate is arranged at the right side of the strut; and the clamping plate is attached to the second die holder. In the using process, the casting die is simple in design structure, convenient to fix the die holders, labor-saving and high in efficiency; a hot-air blower is started up to inject hot air into a heating pipe to carry out preheating on the first die holder and the second die holder so as to reduce defects of forming difficulty, film adhesion,casting cracks and the like, thereby improving production quality; and a water pump is started up and cooling liquid takes the cyclic motion in a cooling pipe to carry out cooling on the die holders,so that cooling efficiency is improved and production machining time is saved, thereby saving cost.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to an automobile brake disc casting mold. Background technique [0002] The brake disc is the friction couple of the disc brake. In addition to the strength and rigidity required as a component, it should also have as high and stable a friction coefficient as possible, as well as appropriate wear resistance, heat resistance, and heat dissipation. and heat capacity etc. The brake disc of the car is made of alloy steel and fixed on the wheel, which rotates with the wheel. The sub-cylinder is fixed on the bottom plate of the brake, and the two friction plates on the brake caliper are respectively installed on both sides of the brake disc. Disc brakes with friction. [0003] At present, the casting of automobile brake discs is usually cast using the conventional single-layer bottom casting method. This casting method has low production capacity, and the casting mold used can only shape...

Problems solved by technology

[0003] At present, the casting of automobile brake discs is usually cast using the conventional single-layer bottom casting method. This casting method has low production capacity, and the casting mold used can only shape the equipment parts. In order to improve the molding efficiency, it is necessary to add cooling equipment for cooling. Increase the cost of casting, and even some manufacturers will use natural cooling, and the production efficiency is low
