What are the factors that affect the mold processing structure?

1. Cavity layout. Determine the number of cavities and their arrangement according to the geometric structure characteristics of the plastic parts, the dimensional accuracy requirements, the batch size, the difficulty of mold manufacturing, and the mold cost.

2. Determine the parting surface. The position of the parting surface should be conducive to mold processing, venting, demolding and molding operations, and the surface quality of plastic parts.

3. Determine the pouring system (the shape, location, and size of the main runner, sub-runner and gate) and exhaust system (exhaust method, exhaust slot location, size).

4. Select the ejection method (ejector, pipe, push plate, combined ejector), determine the undercut treatment method and core-pulling method.

5. Determine the cooling and heating method, the shape and location of the heating and cooling groove, and the installation location of the heating element.

6. According to mold material, strength calculation or empirical data, determine the thickness and dimensions of mold parts, shape structure and all connections, positioning and guide positions.

7. Determine the structural form of the main forming parts and structural parts.

8. Considering the strength of each part of the mold, calculate the working size of the molded part.

If these problems are solved, the structure of the mold will naturally be solved. At this time, you should start to draw a sketch of the mold structure to prepare for the formal drawing.

Main features of mold

Moulds can generally be classified according to the following main characteristics: 1. Classification according to the nature of the process a. Blanking die: A die that separates materials along a closed or open outline. Such as blanking die, punching die, cutting die, slitting die, trimming die, cutting die, etc. b. Bending mold: A mold that makes the sheet blank or other blanks bend and deform along a straight line (bending line) to obtain a workpiece with a certain angle and shape. c. Drawing die: It is a die to make the blank of the sheet into an open hollow part, or to further change the shape and size of the hollow part. d. Forming mold: It is a mold that directly replicates the blank or semi-finished workpiece according to the shape of the convex and concave molds, and the material itself only produces local plastic deformation. Such as bulging molds, necking molds, flaring molds, undulating forming molds, flanging molds, shaping molds, etc. 2. Classification according to the degree of process combination a. Single process mold: In one stroke of the press, only one stamping process is completed. b. Compound mold: There is only one station. In one stroke of the press, two or more stamping processes can be completed at the same station at the same time. c. Progressive die (also called continuous die): In the feeding direction of the blank, there are two or more stations. In one stroke of the press, two or two passes are completed successively at different stations. Die for more than one stamping process. 3. Classification according to the processing method of the product According to different product processing methods, molds can be divided into five categories: punching and shearing molds, bending molds, drawing molds, forming molds and compression molds. a. Punching and shearing dies: the work is done by shearing. Commonly used forms are shearing dies, blanking dies, punching dies, trimming dies, edge dies, punching dies and punching dies. b. Bending mold: It is the shape of bending the flat blank into an angle. Depending on the shape, accuracy and production volume of the part, there are many different forms of mold, such as ordinary bending die, cam bending die, curling Stamping dies, arc bending dies, bending punching dies and twisting dies, etc. c. Drawing mold: Drawing mold is to make flat blank into seamless container with bottom. d. Forming die: refers to the use of various local deformation methods to change the shape of the blank. Its forms include convex forming die, curling edge forming die, necking forming die, hole flange forming die, and round edge forming die. e. Compression die: It uses strong pressure to make the metal blank flow and deform into the required shape. The types include extrusion die, embossing die, embossing die, and end pressure die.

Basic overview of automobile molds

The main component of the automobile mold is the cover mold. This type of die is mainly a cold die. In a broad sense, "automobile mold" is the general term for the molds used to manufacture all parts of automobiles. For example, stamping molds, injection molds, forging molds, casting wax molds, glass molds, etc. The stamping parts on the car body are roughly divided into cover parts, beam parts and general stamping parts. The stamping parts that can clearly express the characteristics of the car's image are the car cover parts. Therefore, the more specific automobile mold can be said to be the "automotive cover stamping mold." Referred to as automotive panel die. For example, the front door outer panel trimming die, the front door inner panel punching die, etc. Of course, not only the car body has stamping parts. All stamping dies on automobiles are called "automotive stamping dies". In summary: 1. Automobile mold is the general name of molds used to manufacture all parts of automobiles. 2. Automobile stamping dies are used to punch all stamping parts on automobiles. 3. Auto body stamping die is a die for punching all stamping parts on auto body. 4. Auto cover stamping die is a die for punching all cover parts on auto body. Now when we talk about automobile molds in this sector, it seems to refer to automobile cover die. In order not to be confused with automobile die in a broad sense, automobile cover die is used instead of automobile die when posting. There are many forms of stamping dies, and the dies are also classified according to the nature of work, mold structure, and mold materials.
