Cement steel mold manufacturing side of the road can be divided into five steps: First, the process analysis of cement steel side of the road side of the road before the cement steel mold design, the designer should be fully analyzed its cement products meets the side of the road steel molds for injection molding processing principle requires careful consultation with the cement side of the road designer products consensus. Including the shape, size and appearance requirements precision products, the necessary discussion unnecessarily complicated as occurs in the production of cement steel mold side of the road. Second, the cement side of the road structure to design a high-quality steel mold concrete mold steel side of the road, not only need to have good processing equipment and skilled manufacturing workers die, another very important factor is to have a good mold design, especially for complex cement side of the road steel mold, mold design quality accounted for more than 80% of the mold quality. A good design is a steel mold cement side of the road: in meeting the request of the premise, the processing cost is low, small processing difficulty, processing time is short. This should be done, not only to fully digest request of the guests, but also on the injection molding machine, mold structure, process and mold their own processing plant capacity understand. Therefore, to improve the level of mold design steel cement side of the road, you should do the following: 1. to understand each side of the road cement steel mold design every detail, to understand the purpose of each part of the mold 2. design The design is similar to the previous multi-reference and understand when the other side of the road steel mold processing and cement production in the case where the experience and lessons learned. 3. To learn more about the working process of the injection molding machine, cement side of the road in order to deepen the relationship between steel molds and injection molding machines. 4. Understand processed process, understanding the characteristics and limitations of each processing. 5. Understand your own design concrete crash barrier steel mold mold tryout results and change the situation, learn from it. 6. designed to maximize the use of the more successful cement side of the road before the steel mold structure. 7. Learn more affected side of the road steel molds for cement products produced. 8. Research cement side of the road some special steel mold structure, the latest tooling technology. Third, determine the cement side of the road steel mold material and selection criteria in the selection of pieces of steel mold material cement side of the road, in addition to considering the accuracy and quality of the product, but also with the actual capacity of processing and heat treatment plant dies to give the right choice . In addition, in order to shorten the manufacturing cycle, as the use of existing standard parts. Fourth, parts machining steel and cement side of the road side of the road cement mold assembly precision steel mold structure in addition to giving the best reasonable tolerances in the design outside, spare parts processing and mold assembly is essential. Therefore, choosing the machining accuracy and machining method has an absolute dominant position in the mold manufacturing. Fifth, a concrete crash barrier tryout steel molds from designing to the assembled, but the completion of 70% to 80% of its entire manufacturing process. For pre-shrinkage and actual shrinkage error produced inconsistent smooth ejection or not, how the cooling effect, especially the gate size, location, shape and appearance affect the accuracy of product and other issues, must be tested by the test mode. Therefore, test mode is to test whether the cement side of the road and choose the best qualified steel mold molding process as an indispensable step.
