Whether the mold design is reasonable or not is an important link to prolong its service life.

Whether the mold design is reasonable or not is an important link to prolong its service life.

Whether the mold design is reasonable or not is an important link to prolong its service life. The extrusion aluminum profile is not equal to the dissymmetry of the section and the unequal thickness of the wall, and should be paid attention to in the design of the die. It should not only consider the arrangement of the position of the die hole, but also combine the concrete conditions to improve the fluidity of the metal by changing the height of the working belt of the die hole. The following are the general problems in the design of Shenzhen mould manufacturer:

1, for unequal profile, the design method of unequal length working belt should be adopted. Ensure the uniformity of metal flow.

2, properly adjusting the radius of the fillet and the length of the working belt can avoid the stress concentration phenomenon.

3, the size of the die hole should be determined by considering the properties of the profiles and the shrinkage of the die materials. For the 6063 aluminum alloy and the commonly used die steel 4Cr5MoSiV, the shrinkage rate of the die hole should be 1.01% to 1.09% when designing, and the size of the die hole should be selected according to the size of the die hole.

4. Determine the number of die holes according to the extension coefficient. The number of die holes directly affects the size of the elongation factor. The extrusion ratio causes the extrusion pressure to exceed the normal value and damage the mold, and the mechanical property of the extruded product will be reduced, and the extension coefficient of the extrusion coefficient should be 10~50.

5. Arrange the position of the mold hole reasonably.
