What impact does mold have on automobile manufacturing

As we all know, parts using mold forming technology have certain adaptability, and are required to be relatively thin and have certain formability. Parts with thickness and diameter such as crankshafts and connecting rods are difficult to punch. At present, it is best to use the mold to make the crankshaft blank first, and then use the cutting process to complete the processing.

The advantage of using custom automotive injection moulds is that it can reduce costs and save time. Computer gong processing can improve production efficiency and make enterprises invincible in the current fierce competition. But today's car manufacturing uses plastic parts, lights, steel shells and other accessories. The real core engine of the car still uses cutting technology instead of mold technology.

In addition to the fact that the engine cannot use mold technology, the crankshaft used in the car cannot use this technology. What is the reason?

The technical level and technical content of mold production have become an important symbol to measure a country's technology and product manufacturing level, and to a large extent determine the product quality, efficiency, new product development capability and international competitiveness of a country's manufacturing industry. According to the development of the mold market at home and abroad, Luo Baihui, a mold expert, speculates that after the adjustment of the industrial structure in the future, the precision of my country's molds will become higher and higher. Mold is the basic process equipment for industrial production. In electronics, automobiles, motors, electrical appliances, instruments, home appliances, and communication products, 80% to 90% of the parts are formed by molds. The shape of the mold determines the appearance of these products, and the processing quality and precision of the mold also determine these Quality of products.

With the increasing economy and living standards, the number of cars is also increasing. Seeing so many cars, I can't help but realize the huge output behind the auto parts mould factories. There is no doubt that China's mold industry has led the development of the automobile industry, so what impact does the mold have on the automobile manufacturing industry, and what requirements does the automobile industry have for the mold industry?

Mold experts believe that adopting advanced mold technology is an inevitable trend to adapt to fierce competition, and it is most important to improve mold competitiveness to meet market demand. JHS mechanical parts processing Improving the high precision of the mold is the need for the development of the mold industry, and it is also the wish of the automobile and other industries.

Strengthen the conceptual understanding of mold precision

1. Mold refers to precision forming tools used for batch forming, stamping and other products. Mold accuracy includes the precision of parts obtained in processing and the quality awareness of product accuracy in production, but mold accuracy usually refers to the accuracy of the working parts of the mold.

(1) The concept of precision in mold processing refers to the degree of conformity between the actual geometric parameters and the design geometric parameters after the Car Dashboard Mould Parts are processed and assembled.

(2) The concept of precision in mold production refers to the various ways of thinking that guide the production behavior of employees gradually formed in the production practice. Quality Awareness.

2. Mold accuracy includes four aspects: dimensional accuracy, shape accuracy, position accuracy and surface accuracy. Since the mold is divided into an upper mold and a lower mold during work, the mutual position accuracy between the upper mold and the lower mold is the most important of the four types of precision.

When the machining accuracy is very high, the mold often cannot do it. The precision of CNC machining center is about 0.1 ~ 0.01 mm. Compared with the previous molds, the machining precision of JHS high-speed computer gongs has been greatly improved. However, the accuracy of parts such as engines is required to be less than one thousandth of a millimeter, or even lower. So it is impossible to completely replace cutting with molds.

Now the finish and roughness of the mold itself have been greatly improved. But the mold itself is also machine-made. If the precision of the machine tool for making the mold itself is not good enough, the precision of the manufactured product will not be high.
