(Summary description)Injection molds can be divided into three types according to different casting systems.

Hot runner mold, hot runner system, also known as hot runner system, is mainly composed of hot sprue sleeve, hot runner plate and temperature control electric box. Our common hot runner system has two forms: single-point hot gate and multi-point hot gate. The single-point hot gate uses a single hot sprue sleeve to directly inject the molten plastic into the cavity. It is suitable for plastic molds with a single cavity and single gate; the multi-point hot gate branches the molten material to each The sub-heat sprue sleeve enters the cavity again. It is suitable for single-cavity multi-point feeding or multi-cavity molds. The structure of this type of mold is roughly the same as that of the nozzle. The considerable difference is that the runner is in one or more with a constant temperature In the hot runner plate and hot nozzle, there is no cold material demoulding. The runner and gate are directly on the product, so the runner does not need to be demolded. This system is also called a nozzleless system, which can save raw materials and is suitable for raw materials. In the case of more expensive products and higher product requirements, design and processing are difficult, and mold costs are higher.

Large nozzle mold: The runner and gate are on the parting line and are demolded together with the product when the mold is opened. The design is quite simple, easy to process, and low cost, so more people use the large nozzle system to work.

Nozzle mold: runners and gates are not on the parting line, usually directly on the product, so it is necessary to design an additional set of nozzle parting lines, the design is more complicated, and the processing is more difficult. Generally, the nozzle system should be selected according to the product requirements. .

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.
