The mud plate is a plate structure installed behind the outer frame of the wheel, usually made of high-quality rubber material, but also using engineering plastics. The fender is usually mounted on a metal baffle, cowhide baffle, plastic baffle, and rubber baffle behind a bicycle or motor vehicle wheel.
The injection molding part of the automobile door plate is located on the inside of the automobile door, installed in the front and back of the door, which is an important part of the automobile interior parts. The automobile door panel is an exterior part, and the welding line is not allowed. When injection molding, the fusion line needs to be driven to the non-appearance area or eliminate the fusion line. By using the 3-point sequential needle valve hot flow channel system, the opening and closing of the 3 hot nozzle heads are controlled by the oil cylinder or cylinder, so as to achieve the injection molding effect without the fusion line. The selection of the glue inlet position is mainly determined by the mold flow analysis, and the type of the glue inlet is mainly determined by the large water outlet and diving. But one thing needs to note:the glue position is in the non-appearance position or after the door panel assembly is not easy to see the position, such as the bottom of the door plate.
The instrument panel is a very unique part of the car, integrating safety, functionality, comfort and decoration. The main die drawing direction of the instrument panel is determined according to the outer surface of the instrument panel and the air outlet position. It is generally between 20 degrees and 30 degrees, and the die drawing direction of the secondary instrument panel is vertical; the direction of the outer surface of the instrument panel is at least 7, which shall be determined on the depth of the surface skin pattern of the instrument panel. The drawing angle of the invisible area should not be less than 3. If less than 3, the surface of the parts may produce other marks, because the use of slider will first affect the appearance of the parts, and then affect the life of the mold, and the mold cost will increase accordingly.
During the injection molding process, the cavity of the mirror shell mold will be affected by high pressure, so the mirror shell mold cavity should have sufficient strength and stiffness. Insufficient strength will lead to plastic deformation and even cracking; insufficient stiffness will lead to elastic deformation, leading to the outward expansion of the type cavity and the overflow gap. Due to the large size of the mold cavity of the automobile rearview mirror shell, the internal stress of the cavity often exceeds the allowable stress before the large elastic deformation, so the strength of the cavity should be checked.
Helmets are divided into full helmets, 3/4 helmets, half helmets, assembled helmets, etc. The main material of the helmet is ABS resin material, which is an engineering plastic with strong impact ability and good dimensional stability.
The automobile lamp mold includes headlight mold and taillight lens mold, etc. The previous CAE analysis is used to predict the molding pressure, reduce the actual molding pressure and reduce the adhesive front mold; for the automobile lamp headlight BEZEL, through the previous CAE analysis, the automobile lamp is very high, so the mold needs to be polished to the mirror.
Mould characteristics:Leiao uses an internal fractal structure for the bumper mold. Compared with the traditional external fractal structure design, the internal fractal design has higher requirements on the die structure and the die strength, inner fractal structure of the mold produced by the bumper mold design concept more advanced.
The size of automobile grid die is large, and the back die has more flat top or small diameter ejector pin, so it is difficult to process, so it needs to be mosaic treatment.
