What is Auto Lamp Injection Mould?

Before you purchase an auto lamp mould, it is important to understand the process involved. This article will discuss the Design challenges, Materials used to make the mould, Construction, and erection mechanisms of this type of mould. It will also address the various types of materials that can be used to manufacture this type of mould. You'll also learn about the benefits of using aluminium for your mould, and why you should use it for your next automotive project.

Design challenges

The design challenges of an Auto Lamp Injection Mould include ensuring the rapid cooling of the plastic part, and the need to achieve precise dimensional accuracy. To achieve this, the mold temperature control system should be optimally designed with the distance of the cooling water channel to the surface of the mold cavity roughly equal to the height of the mold. This allows the mold to cool more quickly, which in turn improves production efficiency.

In addition to the above challenges, automotive lamp assembly parts are typically made of two different plastics. The plastics are often co-molded or overmolded. These parts require threaded inserts. In addition, they are expected to last for years under various environmental conditions. The plastics used in automotive lamp assemblies must be suitable for the assembly's use. Luckily, there are many different software tools to help designers solve these design challenges.

Materials used in manufacturing

Low-density polyethylene, or LDPE, is a popular thermoplastic material. Its properties include excellent chemical and heat resistance. It is also lightweight and transparent, making it ideal for use in plastic bags and other consumer products. Although LDPE has many advantages, its main weakness is that it loses its toughness above room temperature. It also loses its tear resistance when exposed to light. Here are a few common materials used in auto lamp injection mould manufacturing.

Polyamides are plastics that have properties that are ideal for auto lamp injection molding. They are a popular alternative to glass. Nylon is a strong plastic that is lightweight and resistant to heat and abrasion. Although it is not as flexible as glass, it also offers excellent chemical and abrasion resistance and is a popular replacement for metal in some applications. This material is highly durable but also cracks under pressure.

Construction

The Auto Lamp Injection Mould construction involves the design of the mold's movable template cavity. It must also have an overflow tank and push rod. The mold must also possess high strength, high rigidity, and good polishing performance. Its overall volume is small and the structure is compact. In addition, it can avoid complicated procedures. The quality requirements of headlight reflectors are strict, with the inner surface of the reflector requiring high precision. The outer surface can contain thimbles and inlay marks.

The mold's push structure consists of a thimble and a push rod. The plastic part is connected to the top stick of the injection molding machine, which pushes the pushing piece out and back. The mold's sealing surface must be designed according to the tonnage of the injection molding machine, and the size of the lamp mold. It should have a hole positioned at an angle of at least seven degrees.

Erection mechanism

An injection mould is used to create a specific shape. It is also used in the manufacture of plastic products. The proportion of plastic products in the world's market is increasing. As a result, the process of injection moulding is becoming an important processing technology. The most important piece of process equipment is the mould. It is used in the process of moulding and shaping and is the most important part of the manufacturing process.

Inspection methods

Injection moulds are a necessary part of the production process for making automotive lamps. Generally, multiple pieces of a lamp can be produced from a single mold. For front and rear light lamps, design cycles are quick and the components are injection-moulded. To design these moulds, designers first perform a DFM analysis. These designs then undergo a process of testing to check their ease of machining, weldability, hardness, corrosion resistance, and durability. A popular choice for prototype moulds is aluminum. Improved aluminum alloys have a higher hardness and concentration, which makes them better suited for automotive lamp moulding.
