During the automobile manufacturing process, auto lamp moulds
are an important part of the manufacturing process. These lamps are an essential part of a car and have special requirements in terms of appearance, design and mould manufacturing. The automotive lighting fixtures are used to illuminate a car's exterior and interior. These fixtures need to be high quality, easy to use and meet the fluid mechanics requirements.
The automobile lamp mould is a complicated piece of mold tooling, and requires complex and precise machining. Auto lamps can be divided into two types, the lamp base and the lampshade. The base usually has a thermosetting plastic material. The lampshade can be made of ABS or PMMA. These fixtures require a high quality mould design, and also need to be multi-color.
In order to improve the quality of auto lamp moulds, the manufacturer needs to consider several factors. These factors include the mould materials, the mould surface finish and the injection process. It is also necessary to consider the mould pressure, direction and material flow.
For car lights, the mould surface should be smooth and without sharp corners. The mould parting surface is also very demanding. It requires a high-speed machine to smooth the surface. In addition to the smooth surface, the mold is also safe and stable. This is due to the presence of a movable core pulling structure. This structure is especially necessary for molds with a large undercut area. The mold temperature control system should be designed to ensure rapid cooling.
Injection moulding is the preferred method for auto lamp parts. This method allows the mould to complete 100,00 to one million cycles in its lifetime. It is also the most effective method for simple plastic parts. The injection mould can achieve good surface finish and also has the advantage of being light. In addition to the surface finish, injection moulds are also safe.
For the lamp housing casting system, the design includes a first-level hot nozzle and a second-level hot nozzle. This system has a short injection cycle. The material flow speed is high, so the mould's surface finish is excellent. Its dimensional accuracy is high.
The design of the mold must include a vertical water pipe and a spacer water well. This system allows for cooling water to flow to the cavity. It also helps improve production efficiency. The distance between the water channel and the cavity surface is approximately equal. The pressure of the cavity should be as small as possible.
The design of the mould must also consider the size of the lamp, the insertion angle, the position of the discharge, and the shape of the lamp. The design should also consider the optimum injection parameter. This is the most critical part of the mould manufacturing process.
The insertion angle of the mould should be between three and six degrees. This is the maximum insertion angle for a large medium sized mould. This can ensure precise positioning. However, if the insertion angle is less than three degrees, it will be difficult to achieve accurate positioning. In addition, the mould's parting surface should be constructed to guarantee accurate CNC machining.
