Special machine

Injection molding special mold temperature machine is the peripheral equipment of injection molding machine, used to control the mold temperature, the use of the working temperature up to 180℃, the world’s most advanced process design, high temperature control accuracy, fast heat conduction speed, high efficiency and energy saving. And can be configured with automatic suction and return water, full negative pressure operation, RS485 communication and other functions, injection mold temperature machine has been widely used in various injection molding enterprises.

The maintenance

Injection molding machine repair and maintenance:

1. Check whether the mold in operation is in normal condition: whether there is low pressure mold lock protection; Are moving parts such as guide posts, jacking rods, row positions worn and lubricated well? Require at least 12 hours to fill the oil, special structure to increase the number of refueling. Whether the screws and clamping clamps of the mold’s fixed template are loose; Normal production condition: check whether the product defect is related to the mold; When disconnecting the machine, the mold should be comprehensively checked and treated with rust prevention: wipe the cavity, core, ejector mechanism and row position, and spray the mold rust prevention agent or spread butter. After disassembly, the mold shall be placed in the designated place and recorded:

(1) Mold condition: in good condition or to be repaired.

(2) under the mold when the rust treatment.

2.Quarterly routine inspection: mainly clean and maintain the molds that have not been used for more than two months.

(1)Open the mold and check the internal anti-rust effect. If there is any abnormality, the anti-rust treatment shall be carried out again. Molds not in use for a long time should be buttered.

(2) Put back in the original position and make records.

3.Maintenance precautions:

(1) Non-professional maintenance personnel or without the permission of professional maintenance personnel, can not remove the mold maintenance by themselves.

(2). There are small failures in the production process, and the adjustment personnel can solve them according to the situation. Such as: 2.1 Glue mold at the inlet: copper needle should be used to knock out the mold at the inlet, and steel needle and other hard objects should not be used to knock the mold. 2.2 Cavity slight mold marks, polishing materials can be selected according to the cavity finish. The SURFACE OF GRAIN CANNOT USE POLISHING MATERIAL SUCH AS SANDPAPER, DIP IN WITH COPPER BRUSH COMMONLY DRILL GESSO OR KING KONG MORTAR SCRUB, COMPLETE BY PROFESSIONAL MAINTENANCE PERSONNEL. 2.3 Product adhesive mold: Generally, hot plastic is used to cover the product and the ejection part, and then ejection after cooling. If using fire, be careful not to damage the surface of the mold.

(3) When professional personnel repair the mold, the structure can not be changed at will, and the need to change the structure must be approved by the quality engineering department.

(4) Ensure the quality of maintenance, select appropriate equipment, materials, tools and the method of solving the problem, and complete it at the fastest speed.

4.Quality record:

Maintenance record sheet of injection molding machine and mold.

I. Purpose: To standardize the use and maintenance of plastic injection mold, reduce mold damage, and ensure that the production quality meets customer needs.

2.Responsibilities: THIS STANDARD MUST BE TRAINED BY QUALIFIED INJECTION TECHNICIANS. 2.2 Injection foreman is responsible for implementation, inspection and supervision, and supervisor regularly supervises.

Prospects for development

In 2008, the global export volume of injection molding machines was 5.46 billion US dollars. Among them, the scale of injection molding machine industry in Germany ranks the first in the world, and the total export volume accounts for more than 20% of the world’s total export volume, which is in a dominant position in the global injection molding machine competition. Italy and Japan ranked second and third respectively. America’s share of injection molding machine exports has been declining year by year, from 9.8% in 2000 to 5.3% in 2008. Japan’s electric injection molding machine occupies an important position in the world, and the share of electric injection molding machine in North America has reached about 30%.

The injection molding machines in Europe, America and Japan are mainly precision injection molding machines and large injection molding machines with high technology content and high added value. After years of technology introduction and innovation, the manufacturing level of China’s plastic machine industry in the field of low-end injection molding machine is almost the same as that of developed countries. Coupled with the advantage of labor price, China’s low-end injection molding machine export occupies half of the world. In addition, the Chinese plastic machine industry has not only made great progress in the field of mid-end injection molding machine, but also made important breakthroughs in the field of high-end injection molding machine. The market share of Chinese plastic machine is expected to gradually expand.

In terms of the global market pattern, the continuous development of the global construction market will drive the demand for extruded products such as plastic pipes and siding, and then drive the demand growth of extrusion equipment. Therefore, the global demand for extrusion equipment is expected to exceed that of other types of plastic machine products. According to a survey by Industrial Market Research, demand for plastic machinery in the United States and Japan will show signs of recovery again, and demand in Western Europe will accelerate in 2009. China, India and Russia plastic machinery sales prospects. Turkey, Czech Republic, Iran and other developing countries and regions, the demand for plastic machinery will also gradually increase.

China production injection molding machine manufacturers more, according to incomplete statistics has more than 3000. The structure of injection molding machine has two kinds: vertical and horizontal. According to the products produced can be divided into ordinary injection molding machine and precision injection molding machine. One injection volume 18-51000g; The clamping force is 30-36000kN; Processing raw materials are thermosetting plastics, thermoplastics and rubber three. Thermoplastics include polystyrene, polyethylene, polypropylene, nylon, polyurethane, polycarbonate, plexiglass, polysulfone and (acrylonitrile/butadiene/styrene) copolymer (ABS), etc. From the processed products, there are monochrome, two-color general and precision plastic products.

Ordinary horizontal injection molding machine is still the dominant direction of the development of the injection molding machine, its basic structure is almost no big change, in addition to continue to increase their control and automation level, reducing energy consumption, the manufacturers according to the changes of the market is to develop in the direction of combination series, as a type of large, medium and small three kinds of injection molding machine configuration injection device, combined into standard and combination, Increased flexibility, expanded the scope of use, and improved economic benefits.

Injection molding machine manufacturers in the world’s industrially developed countries are constantly improving the function, quality, supporting capacity of auxiliary equipment, and automation level of ordinary injection molding machines. At THE SAME TIME, THE DEVELOPMENT of large injection molding machines, special injection molding machines, reaction injection molding machines and precision injection molding machines, to meet the production of plastic alloy, magnetic plastic, plastic products with inserts demand.

Injection molding machine is one of the plastic machine varieties with the fastest development speed and the smaller gap between the level and industrial developed countries in China. But mainly refers to the ordinary injection molding machine, in large, all kinds of special, special, precision injection molding machine of most varieties, some products are still blank, which is the main gap with the industrial developed countries
