Suzhou Jiupeng intelligent introduction: injection mold application range

Injection mold plays a vital role in injection molding production. Injection mold is a process of manufacturing products with certain size and quality through the design of material, shape, size and motion trajectory. Injection mold is a type of molding parts by pressing plastic directly into the mold cavity. According to the type of injection molding machine, injection mold can be divided into manual injection molding machine, semi-automatic injection molding machine and automatic injection molding machine.

According to the injection mold material, the current common injection mold materials are the following: steel, cast iron and aluminum alloy. There are also carbon fiber reinforced composites, epoxy resins (EP), polycarbonate (PC), etc. These materials can greatly improve the impact resistance of injection molds, but in some cases these materials can affect production quality or reduce costs.

It is important to choose a different injection mold according to the material used, as some materials may not work with the injection mold, resulting in some parts being damaged or unusable. The following to introduce the role of injection mold in the production of plastics and its classification:

1. Injection mold generally includes cavity, forming system and machine, of which the main role of the forming system is to mix plastic particles, and then forming. For plastic products, their shape is determined by the nature of plastic, production conditions and other factors.

2. In order to obtain good appearance quality, the cavity of injection mold is generally relatively deep.

3. The injection mold is the first plastic molding into parts, and then the parts are assembled into the mold, and finally installed on the injection machine.

4. Injection molding machine is composed of hydraulic system, electrical control system, hydraulic pump station and mechanical transmission device.

5. In the process of injection molding, in order to ensure the quality of the product, it is necessary to use a certain degree of mold structure to ensure the required size and shape. Above is the plastic industry most commonly used to several types of mold structure and its role in injection production and characteristics!

Two. Injection mold according to the structural form can be divided into three types: integral (such as large vertical injection molding machine), combined (such as small horizontal injection molding machine), combined (such as double station small horizontal injection molding machine).

Injection molds are molds used to produce plastic products. It usually consists of molding system, injection molding machine, stripping system and cavity system. Here, we will introduce several typical injection mold structures. Injection molding product structure refers to the design process of injection molding machine injection mold, which components of the product structure. The plastic injection mold refers to the plastic parts composed of which parts, usually including the plastic molding system; Core; Cooling system, etc. Among them, the performance of the injection mold depends on the cavity structure to a large extent, so the injection mold is also called the cavity.

Three. According to the classification of materials, injection mold is generally divided into steel and cast iron, etc., they have high strength and wear resistance, and aluminum alloy has good impact resistance, but is not suitable for high temperature environment, so aluminum is a kind of high temperature resistant material.

In addition, the design and manufacture of the mold also involves the melting and filling of plastics in the process of plastic processing. 4. According to the classification of materials, the basic materials commonly used in injection mold are steel, aluminum alloy and stainless steel.

For steel, its advantages are strong corrosion resistance, good temperature resistance and cheap price, but it is difficult to process, forming parts are easy to deformation. For aluminum alloy, its advantages are high strength, good hardness, but high processing cost. Stainless steel has good corrosion resistance and surface gloss, but its disadvantage is difficult to process and high cost. At present, the main materials of injection mold are as follows:.
