The most important part of automobile die is panel die. This kind of die is mainly a cold stamping die. In a broad sense, "automobile mold" is the general name of molds for manufacturing all parts on automobiles. Such as stamping die, injection die, forging die, casting wax die, glass die, etc. When people talk about cars, the first thing that comes to mind is the body. In other words, the car body is the symbolic assembly of the car. The body represents the image characteristics of that car. In a narrow sense, automobile die is the general term for stamping all stamping parts on automobile body. Namely "automobile body stamping die". For example, the top cover flanging die, the cross beam reinforcing plate pressing die, etc. Stamping parts on automobile body are generally divided into covering parts, beam parts and general stamping parts. The stamping parts that can clearly show the characteristics of automobile image are automobile panels. Therefore, the more specific automobile die can be said to be "stamping die for automobile panel". Short for stamping die for automobile panel. For example, front door outer panel trimming die, front door inner panel punching die, etc. Of course, there are more than just stamping parts on the car body. All stamping dies on automobiles are called "automobile stamping dies". To sum up: 1. Automobile mold is the general name of the mold for manufacturing all parts on the automobile. 2. The automobile stamping die is the die for stamping all stamping parts on the automobile. 3. The stamping die for automobile body is a die for stamping all stamping parts on automobile body. 4. The stamping die for automobile panels is a die for stamping all the panels on the automobile body. Now, when we talk about automobile dies in this section, it seems that we all refer to automobile panel dies. In order not to be confused with the generalized automobile mold, it is best to use the automobile panel mold instead of the automobile mold when posting. There are many forms of stamping dies, and stamping dies are also classified according to working nature, die structure and die material. Generally, it can be classified according to the following main characteristics: 1. According to the nature of the process, a. A die is a die that separates materials along a closed or open contour. Such as blanking die, punching die, cutting die, cutting die, trimming die, cutting die, etc. B. Bending die is a die that bends a blank or other blanks along a straight line (bending line) to obtain a workpiece with a certain angle and shape. C. Drawing die is a die for making blank plates into open hollow parts or further changing the shape and size of hollow parts. D. The forming die is a die that directly replicates and forms a blank or semi-finished workpiece according to the shapes of the male die and the female die, and the material itself only produces local plastic deformation. Such as expanding die, necking die, flaring die, wavy forming die, flanging die, shaping die, etc. 2. Classification according to the degree of process combination A. A single-process die is a die that only completes one stamping process in one stroke of the press. B the compound die has only one station, and in one stroke of the press, two or more stamping processes are simultaneously completed at the same station. C. The progressive die (also called the continuous die) has two or more stations in the feeding direction of the blank, and in one stroke of the press, two or more stamping processes are continuously completed at different stations. 3. According to the classification of product processing methods, dies can be divided into five categories: stamping and shearing dies, bending dies, drawing dies, forming dies and compression dies. A. Punching and shearing die: the work is accomplished by shearing. The common forms are shearing die, blanking die, punching die, trimming die, edging die, hole drawing die and punching die. B. Bending die: bending a flat blank into an angle. According to the shape, precision and output of parts, there are many different types of dies, such as common bending die, cam bending die, curling die, arc bending die, bending punching die and torsion die. C, die drawing: die drawing is to make a flat blank into a seamless container with a bottom. D. Forming die: refers to changing the blank shape by various local deformation methods, including convex forming die, curling forming die, necking forming die, hole flange forming die and round edge forming die. E. Stamping die: The metal blank is made to flow and deform into the required shape by strong pressure, and its types include extrusion die, embossing die, embossing die and end stamping die.

Various tire vulcanization molding dies. Automobile tire mold classification 1: movable mold, which consists of pattern ring, mold sleeve and upper and lower side plates. The movable die is divided into two parts: the movable die facing the conical surface and the movable die facing the inclined surface: two halves, consisting of an upper die and a lower die. The processing technology of automobile tire mold takes the moving mold as an example 1: casting or forging the blank according to the tire mold diagram, rough machining and heat treatment of the blank. The blank of tire mold should be completely annealed to eliminate internal stress, and leveled during annealing to avoid excessive deformation. 2. Punch the hanging hole according to the drawing, then process the outer diameter and height of the pattern ring in place according to the semi-finish turning drawing, turn the inner cavity of the pattern ring with the semi-finish turning program, and check with the semi-finish turning sample after turning. 3. Use the processed tire mold pattern electrode to form a pattern in the pattern circle with electric spark, and check with the sample. 4. Divide the pattern ring into several parts according to the requirements of the manufacturer, draw the marking lines respectively, put them into the tooling, punch the back waist hole and tap. 5: According to the equal parts divided in step 8, cut at the scribe line. 6. According to the requirements of the drawings, the cut pattern blocks shall be polished, chamfered, rooted and exhausted. 7: Sandblasting should be carried out evenly in the cavity of the pattern block, and the color should be consistent. 8. Assemble the pattern ring, mold sleeve, upper and lower side plates to complete the tire mold. There are many ways to classify plastic molds, which can be divided into the following categories according to the different molding methods of plastic parts: injection mold injection mold is also called injection mold. The molding process of this mold is characterized in that plastic raw materials are placed in the heating cylinder of the injection molding machine. The plastic is heated and melted, pushed by the screw or plunger of the injection machine, and enters the mold cavity through the pouring system of the nozzle and the mold. The plastic is solidified in the mold cavity after heat preservation, pressure maintenance, cooling and molding. Because the heating and pressurizing device can play a role in stages, injection molding can not only shape plastic parts with complex shapes, but also have high production efficiency and good quality. Therefore, injection molding occupies a large proportion in the molding of plastic parts, and injection molds account for more than half of plastic molding molds. Injection molding machines are mainly used for the molding of thermoplastics, and in recent years, they are also gradually used for the molding of thermosetting plastics. The compression mold is also called compression mold or glue mold. The molding process of this mold is characterized by directly adding plastic raw materials into the open mold cavity and then closing the mold. After the plastic is in a molten state under the action of heat and pressure, the mold cavity is filled with a certain pressure. At this time, the molecular structure of plastic produced chemical crosslinking reaction, and gradually hardened and shaped. Molds are mostly used for thermosetting plastics, and the molded plastic parts are mostly used for the housings of electrical switches and daily necessities. Transfer die Transfer die is also called injection die or extrusion die. The molding process of this mold is characterized by adding plastic raw materials into the preheated feed chamber, and then the pressure column exerts pressure on the plastic raw materials in the feed chamber. Plastic melts at high temperature and high pressure, enters the cavity through the gating system of the mold, and then undergoes chemical crosslinking reaction and gradually solidifies. Transfer molding technology is mostly used in thermosetting plastics, and plastic parts with complex shapes can be molded. Extrusion die extrusion die is also called extruder head. This mold can continuously produce plastics with the same cross-sectional shape, such as plastic pipes, bars and sheets. The heating and pressurizing device of the extruder is the same as that of the injection molding machine. The molten plastic will form a continuous molded plastic part after passing through the mold, and the production efficiency is particularly high. In addition to the above types of plastic molds, there are vacuum molding molds, compressed air molds, blow molding molds, low foam plastic molds and so on.
