The standard mold base generally consists of the fixed clamp plate of upper mold, the fixed mold plate, the movable mold plate of lower mold, the movable mold support plate, the padding block, the moving clamp plate, the push bar fixing plate, the stripper plate, the guide pin, the guide bush and the reset lever and so on. In addition, there are some mold bases with special structure, such as point gate mold base, mold base with stripper plate push out, etc. Other parts of the mold base can be supplemented as needed, such as precision positioning devices, supporting columns and other accessories. Basically, the accessories need to be used are already including in the standard mold base.
The mechanical arm during injection molding is generally composed of execution system, drive system, control system etc. The execution and drive system is designed to perform the normal functioning of mechanical arm. Driving mechanical parts by pneumatic or electric motor to reach the function of taking out objects. With the wide application of mechanical arm, insert, shear products glue and simply assemble are more convenient.
The accuracy concept is the basic concept and consciousness that mold designers must establish. Mold accuracy includes overall mold assembly and zero and component position and shape dimensional accuracy, mating accuracy, and positioning accuracy. Such as die punching gap value and uniformity, plastic injection mold, die casting mold positioning and positioning accuracy, etc., need to be the shape of the punch and die, position accuracy, guide device position and match accuracy.
Therefore, strict dimensional accuracy design and calculation are required in the mold design. At the same time, the manufacturing process and precision of the parts and components must also be considered to ensure the precision of the mold.
In recent years, the manufacturing industry has become more and more fierce in the world, and the ability to provide customers with high-quality products with high efficiency and low consumption in the shortest possible time has become a symbol of the competitiveness of companies. The mold is called the father or industry. The quality of the mold will directly affect the quality of the product, its production, its cost, the time it takes for the new product to be put into production and the replacement of the old product, the speed at which the company's product structure is adjusted, and the market's competitiveness. The quality of the mold has raised higher and higher requirements. So how can we improve mold quality more reasonably? In other words, how can we allow the mold to produce quality-qualified parts more accurately and at low cost and high efficiency over a longer period of time and with more modes? This has increasingly become the focus of attention. Mold quality is not a simple topic.
The service life of the injection mold is directly related to the production cost and efficiency of injection molding parts processing. If the injection mold has a high service life, on one hand, the production cost can be reduced, and on the other hand, the processing efficiency can be improved. So how can we improve the life of injection molds? Years of practice have shown that in order to improve the service life of injection molds must be considered from the following aspects.
The heating, insulation and cooling of the mold and the clamping structure are an integral part of the design of the composite mold. The structural design directly affects the appearance and inherent quality uniformity of the product, and also affects the forming efficiency of the product.

Molding process is one of the most common and oldest molding methods for plastic materials, and it is one of the most commonly used techniques for studying material properties. It has the advantages of simple molding device, small equipment investment and simple mold structure. It is still one of the most popular production methods in today's highly developed mechanized and automated production. However, for the mold design of compression molding, few sums up the key skills in mold design. This article will explain heating, insulation and cooling design.
Mold processing refers to the processing of forming and blanking tools, and also includes shear and die cutting dies. Under normal circumstances, the mold has two parts: the upper mold and the lower mold. The steel plate is placed between the upper and lower molds, and the material is formed under the action of a press. When the press is opened, the work-piece determined by the shape of the mold is obtained or the corresponding scrap is removed. From small electronic connectors to large parts of the car dashboard can be molded. A progressive die is a set of dies that can automatically move a machined work piece from one station to another and obtain a molded part at the last station. Mold processing technology includes: cutting die, punch blank die, composite die, extrusion die, four slide rail die, progressive die, stamping die, die-cutting die and so on.
The first step is to start with technology and establish a sound intellectual property system to achieve the full development of China's mold. After that, it will gradually apply industrial technologies that have been gradually accumulating to realize autonomous industrial production and comprehensively improve industrial competitiveness. Throughout the 12th Five-Year Plan period, China's mold will be a market environment where challenges and opportunities coexist.

Thermoplastic injection molding is to melt the plastic material and then inject it into the film cavity. Once the molten plastic enters the molds, it is shaped into a certain shape by the cold mold cavity. The resulting shape is often the final product, and no further processing is required before installation or use as a finished product. Many details, such as protrusions, ribs, threads can be molded in a one-step injection molding operation.
China's domestic mold technology has made rapid progress in the past two years. The main manifestations are: the popularity of mold integration manufacturing cell and technology, commercial internet extending to the mold and its industrial chain, 3D printing is widely used in mold manufacturing, intelligent mold, appearance and optimization of light weight new materials and large plastic molds, the maturity of large-scale progressive die technology, high-speed and high-reliability become important features of precision progressive die, mold standard parts tend to refine.
At present, China's annual output value of plastic molds is about 53.4 billion yuan. Do you believe that the rapid development of the Chinese economy has become more and more stringent for the plastic mold industry, thus providing a huge impetus for the development of the plastic mold industry. According to current accurate statistics, China's annual plastic mold output value reached 53.4 billion yuan, which is an existing fact.
With the rapid development of automobile manufacturing and IT manufacturing, the domestic mold factory has achieved rapid development in recent years. It is understood that the proportion of plastic molds in the mold industry in China can reach 30%. It is expected that in the future mold market, plastic mold will account for the proportion of total molds will continue to increase, and the speed of development will be faster than other molds.
Injection mold
Plastic molds are tools in the plastics processing industry that are used in conjunction with plastic molding machines to give plastic products a complete configuration and precise dimensions. According to the different molding methods, it can be divided into different types of molds.
