【正文】 to affect efficiency of plastic products production, injection mold in the mold operation, its temperature is 80℃ or so, only a tiny part of the temperature will be lost to the atmosphere, but nearly 75% of temperature depends on the mold cooling system technology to plete. Effective application of the cooling system technology can shorten the molding cycle of plastic products, fundamentally improve the production efficiency. 黑龍江八一農(nóng)墾大學(xué)畢業(yè)論文（設(shè)計(jì)） 31 The influence of the size plastic Plastic is divided into a lot of kinds, which is more mon crystalline plastics and a different kind of soft plastic. Any kind of plastic in the process of production is inseparable from the application of the cooling system technology for the crystal type of plastic, the cooling system technology application, the better, the production of plastic products with better shape and size of the standard。 For soft type of plastic, the lower the temperature of the cooling system, the quality of the product, the influence of molding products In addition, the cooling system of injection mold products molding play a crucial role. Under the condition of reasonable operation, a fortable temperature, injection mold in the process of production to maintain the stability of the product shape, will bend plastic product lines, product shape to minimize the risk of damage. 2 injection mold cooling technology pulse cooling technology In recent years, the pulse cooling technology is gradually used in the production process of injection mold. Pulse cooling technology with the traditional cooling system there exist certain differences, the main is the cooling fluid flow of the injection mold for proper adjustment, adjust cooling fluid flow according to the temperature of the injection mold is how much of it can maximize the temperature of injection mold and die cooling fluid temperature difference of narrow, speed up the cooling time of injection mold, further enhance the efficiency of the production of plastic products. Pulse cooling technology, however, there are some shortings, mainly in the process of its application in operation there are multifarious, in order to keep the temperature of the injection mold balance, will increase the cooling technology in the middle of the pulse cooling technology distinction, and for each partition for cooling temperature detection. The CO2 gas cooling technology According to the conditions of application of the technology will mold production material replace with CO2 gas cooling technology to supporting the use of metal material, mold production in the process of CO2 gas injection, to reach the effect of cooling. CO2 gas cooling technology can enhance the efficiency of the production of plastic products, 黑龍江八一農(nóng)墾大學(xué)畢業(yè)論文（設(shè)計(jì)） 32 at the same time also can ensure the quality of its products, the cooling technology in the process of application need only will be closing the mold vent, pared with the traditional cooling technology of its operating structure is simple. However, CO 2 gas cooling technology in the process of practical application, its application range is small, use easily restricted. This is mainly due to two aspects, one is that if the application of CO2 gas cooling technology, the requirement for mold of metal, but its cost is higher, manufacturers not be monly use. Second, the application of CO2 gas cooling technology for technical talented person39。s demand is higher, narrowing the scope of technical personnel. The conformal cooling technology With the development and application of the injection mold cooling system, the technology of the cooling system has been developed. Compared with traditional technology, injection mold in cooling process to the cooling pipeline assignment to mold, the mold cooling area expanded, and by the cooling parts of uniform, can achieve the expected mold cooling effect. On the basis of this, the conformal cooling technology has improved the production efficiency of plastic products. The traditional mold cooling technology has some defects, the most obvious is that the cooling part is not balanced. To want to take plastic products to see mold production materials are cooling, uneven cooling very easy to extend the time for the cooling of plastic products, the impact of the production efficiency, and ultimately affect the economic efficiency of enterprises. The application of the conformal cooling technology can improve the efficiency of traditional plastic products by 30%. On the basis of this, the application of the conformal cooling technology is simple and the production cost is not high. 3 conclusion Cooling system technology belongs to one of the main technology of injection mold production, the manufacturer of plastic products, plastic products, production efficiency, quality enterprise production and operation efficiency, etc will play a crucial difference. At first, this paper is the impact of technology of injection mold cooling system is expounded, and according to our country in recent years several new cooling technique is analyzed, through the research on the advantages and disadvantages of the different 黑龍江八一農(nóng)墾大學(xué)畢業(yè)論文（設(shè)計(jì)） 33 cooling technology, think conformal cooling technology have greater prospects for development, mainly is the cooling technology has good cooling function, can reduce the mold cooling time, improve production efficiency。 Cooling technology at the same time, the operation is simple, to a certain extent, expanded the scope of use, production cost is low, the cooling technology allows manufacturers maximize economic benefits.
