Description

Technical Field

[0001] This utility model relates to the technical field of modular engine throttle body die casting molds, specifically a modular engine throttle body die casting mold. Background Technology

[0002] With the continuous progress and development of society and economy, people's living standards are constantly improving, and automobiles have become an integral part of daily life. During the operation of a car, the engine relies on converting the chemical energy of gasoline into mechanical energy to provide power. The throttle body is the most important component of today's engine system, used to regulate the intake air volume of the engine. Its upper part is the air filter, and its lower part is the engine block. It is the throat of the car engine. There are two types of throttle bodies: traditional cable-operated and electronic. The smoothness of the car's acceleration is closely related to the cleanliness of the throttle body. After a period of use, the throttle body is prone to excessive sludge. Therefore, the throttle body needs to be replaced regularly according to the usage conditions, making the throttle body a car part with a large demand in the market. However, the current production and manufacturing of throttle bodies is relatively complex, and the mold universality is poor, which cannot meet the market demand. Therefore, it is necessary to design a throttle body mold that is simple in design and can achieve modularity. In the prior art, such as the authorized announcement number CN205437100U, this utility model discloses a modular engine throttle body die-casting mold, including a base plate module, a first shaping module, a second shaping module, a cover plate module, and a throttle body casting cavity. The first shaping module is arranged above the base plate module, the second shaping module is arranged above the first shaping module, and the cover plate module is arranged above the second shaping module. A positioning pin is arranged on the left side of the cover plate module, and fixing bolts are arranged around the cover plate module. A gate is arranged inside the cover plate module, and a gas flow hole is arranged on the left side of the gate. An inner flow channel is arranged inside the second shaping module, and a throttle body casting cavity is arranged below the inner flow channel. A first sliding module is arranged on one side of the throttle body casting cavity, and a second sliding module is arranged on the other side of the throttle body casting cavity. The beneficial effect is that the mold has a simple structure, is easy to use, realizes modular design, and improves the versatility and interchangeability of the mold. In the aforementioned modular mold, the upper and lower molds are fixed by positioning pins when they are closed, which makes it inconvenient to close and fix the mold, inconvenient to open the mold, and inconvenient to control the moving mold core on the side. In addition, the integrated design of the casting gate makes it inconvenient to clean the inside of the casting channel when cleaning after the mold is opened. Utility Model Content
