How To Choose The Mold Spring?
Original: | Author: Jasmine HL of DGMF | Publish Time: 2018-01-20 | 9123 Views | Share:
In almost all stamping dies, a large number of elastic elements, mold springs are used. Among these elastic originals, there are various elastic standard parts, urethane, gas springs, etc. Different elastic originals are selected according to different needs.

Mold Springs include rectangular mold springs, wire mold springs, etc. The intention of the mold spring is to unload and press the material. The strength of the tension mold spring is related to the smooth production of the mold and the qualified products. The mold spring force of the mold spring is small, and it is very easy to cause various problems such as the product being deformed due to the inability to hold the material, the mold not to be unloaded, the product not easy to be taken out of the mold, the material to be fed, and the knife-edge and the punch to be simply worn.

Rectangular mold springs are generally classified according to their color: brown, green, red, blue, and yellow, and their elasticity also weakens. Depending on the color, the elasticity is different, and the amount of compression is also different.

Here is a soil method to calculate the compression amount of the mold spring: we measure the total height of the mold spring in advance, put the mold spring in a bench vise, lock it, and then use a caliper to measure the remaining length after the spring is clamped, and then use the mold spring Subtract this number from the total length, and divide by the total length. This method is common to any mold spring. For example, a brown spring with a length of 60mm should be left with about 45.6 after being clamped by a vise. Subtracting 45.6 from 60 equals 14.4, then dividing 14.4 by 60, the result is equal to 0.24, and this is its compression.
