The slope protection mold is extruded by an iron mold at high temperature. The iron mold plays a decisive role in improving the quality of the slope protection mold, prolonging the life of the slope protection mold, and improving the production efficiency.
1. Improving the design of slope protection mould
Whether the design of slope protection mold is reasonable is the basis of improving the utilization rate of slope protection mold. Therefore, effective measures should be taken to improve the durability of the slope protection die in order to improve the durability of the slope protection die. For example, the life of the slope protection die with small holes is often shown in the punch with small holes. For this kind of slope protection mould, the length of the small punch should be shortened as far as possible to increase the strength. At the same time, the guide sleeve should be used to strengthen the protection of the small punch. In addition, in the design of the slope protection mould, the form of the mold base, the fixing method and guiding form of the punch and concave die, the determination of the pressure center and the rigidity of the upper and lower formwork should be fully considered. Especially for the slope protection mold, the selection of clearance value has a great impact on the durability. In the design, the gap of the slope protection die should be selected reasonably, and the clearance value should not be too small, otherwise the service life and durability of the stamping die will be affected. Practice has proved that the durability of slope protection mould can be greatly improved by properly enlarging the clearance without affecting the quality of parts, sometimes even several times or dozens of times.
2. Correct selection of slope protection mold material
Different slope protection mold materials have different strength, toughness and wear resistance. Under certain conditions, the durability can be increased several times by using advanced materials. Therefore, in order to improve the utilization rate of slope protection mold, it is necessary to select good materials.
3. Reasonable arrangement of slope protection mould manufacturing process and guarantee of machining accuracy
The machining accuracy has a great influence on the utilization rate of slope protection mould. The shape of the slope protection mold is completely consistent with the shape of the iron mold, and the two are closely related. In order to ensure the quality of the slope protection mold produced, the professional R & D personnel are required to carry out reasonable design and development of the iron mold, and it must be considered that the mold is good and does not deform.
