Casting is the foundation of the manufacturing industry and the basic industry of the national economy. However, due to the early start and rapid development of foreign developed countries, there is still a certain gap in the efficiency of castings produced in my country compared with industrial developed countries. One of the main reasons is that the level of mechanization, automation and informatization in my country's foundry industry is relatively low.

At present, the molding speed of the molding machines produced by most domestic manufacturers is about 80-90 molds/hour, which is far lower than that of foreign high-end products. Although the production efficiency of foreign molding equipment is high, most of the equipment is positioned in the high-end market, and more products are sold in standard sets, and the price is high, which is difficult for domestic small and medium-sized enterprises to accept. Moreover, the supply of spare parts for foreign high-end brand products is relatively scarce, and there are certain difficulties in maintenance. This situation has affected the development of my country's foundry industry.

In recent years, the state has successively launched policy documents such as "Made in China 2025" and "Industrial Structure Adjustment Guidance Catalog (2019 version)" to vigorously support the development of high-end equipment manufacturing and new material industries in order to break the technological blockade of foreign brands. In this context, my country's foundry equipment industry has been well developed. Among them, DLZX5060SX, DLZX6070SX and other series of Automatic Molding Machines with upper and lower sand shooting double stations produced by our company (Delin Intelligent) were successfully developed and put into the market under this background.

The upper and lower sand injection double-station automatic molding produced by our company (Delin Intelligent) is a fully automatic casting production equipment used to produce casting sand molds. The loose molding sand is automatically injected into the sand frame through compressed air. Solid, mold lifting, box closing, demoulding, pushing and other automatic actions in sequence, which are widely used in valves, bearing housings, pulleys, pump bodies, hydraulic parts, pipe fittings, agricultural machinery parts, furnace accessories, machinery and auto parts, etc. Molding production of casting sand molds. It has the advantages of double-station operation, synchronous molding and sand core setting, and high efficiency of sand shooting, demoulding and pushing. The molding speed can reach about 180 molds/hour. It has a simple and reasonable structure, small footprint, and good working stability. And the cost is much lower than that of foreign competitors.

Since the molding speed of the automatic molding products produced by our company is about 180 molds per hour, the functions can be customized according to the needs of customers, such as: "Customize the height of the sand mold, customize the length and width of the sand mold, and make sand molds that are not easy to produce. It can greatly meet the diverse needs of customers, and effectively solve the problem of serious faults among skilled workers in foundry enterprises. The company has nearly 80 after-sales service outlets around the world, which will provide customers with global service support, high-efficiency molding equipment and a global after-sales service network, effectively breaking the technical blockade of foreign brands, and can effectively solve the problem of casting The problem of serious disconnection between engineering and technical personnel and skilled workers in enterprises will promote the sustainable and healthy development of the foundry industry.

In the field of casting molding equipment, the domestic industrial development is relatively late, and there is still a big gap between Chinese enterprises and foreign countries, and they are developing from manual, semi-automated to fully automated.

Research on casting technology and equipment:

Since the shock-type molding machine appeared in the 1940s, after decades of development, the molding machines have successively appeared shock-type molding machines, high-pressure compaction molding machines, injection-pressure type boxless molding machines, air-impact molding machines and Static pressure molding machine, etc. These molding machines can work continuously without interruption, with high molding efficiency and good sand quality. At present, automation has been fully realized, and it is developing in the direction of intelligence. At present, foreign molding machines are mainly produced by German, Danish, American and Japanese brands.

The requirements for energy saving and environmental protection are higher, and the goal is to achieve high-quality batch continuous production:

The foundry industry is a labor-intensive, energy-intensive, and highly polluting industry. The annual output of castings in my country now ranks first in the world. However, domestic small and medium-sized foundry companies tend to have customized requirements (such as the height of the sand mold, the length and width of the sand mold, etc.), and there are some companies that will or single-machine companies, and most foundry companies are mainly suitable for occasions that require high performance. In this project, our company's technology center and production center will carry out innovative designs on the shape of the upper and lower boxes, the rotating mechanism, the box-unloading mechanism, the pushing and connecting mechanism, and the exhaust of the sand cylinder.
