The door is an important part of the auto interior parts. It is located on the inside of the car door. It is divided into front, rear, left, and right. It varies according to the car system, usually two doors and four doors. These parts are collectively called door panel series.

The material of the door is generally PP+EPDM, and EPDM can improve the elasticity of the door panel. The exterior surface of the car door has high requirements, and the exterior surface of the plastic part needs to be textured. Spots, gate marks, shrinkage depressions, weld marks, flashing and other defects are not allowed. There are 12 undercuts on the inner side of the door. During injection moulding, the weld line must be driven to the non-appearance surface or eliminated. This is one of the key and difficult points in the door mould design. ANO's car door mould uses 10-point sequential valve hot runner gate control technology, which controls the opening and closing of 10 hot nozzles through the drive of an oil cylinder, thereby achieving the ideal effect of no weld marks on the surface of the plastic part.

The door panel parts generally have horn meshes. The door mould meshes can be formed by inserts. In addition, ANO installs the mesh inserts on the pushrod, which not only solves the problem of difficult mesh exhaust, but also solves the problem of mesh ejection. Difficult question. The mesh insert material has strict requirements, generally S136 or breathable steel.

The car door panel is one of the most important interior parts of the car, so the design of the temperature control system has a great influence on the moulding cycle of the mould and the quality of the product. One of the design principles of the cooling water channel is that the distance from the cavity surface should be approximately equal to achieve approximately equal temperature throughout the mould cavity. The temperature control system of the ANO door mould adopts the combination of "straight-through water pipe + inclined water pipe + water well". Its advantages are uniform cooling of plastic parts, short moulding cycle, high moulding quality, and it is suitable for moulds with high requirements and high appearance performance requirements. In the design of automobile moulds, it is similar to the interior and exterior trim moulds such as automobile front and rear bumpers, instrument panels, central channels, grilles, automobile trim strips and other interior and exterior plastic parts.
