This paper grasp 5 kinds of column injection molding machine processing process

The lower the time is, the better. The cycle time time includes the following: glue shooting time, dry time, glue melting time, refrigeration time, ejection time, lock mold bottom pressure time. Even related to the time factor is the return mold and lock mold, and ejection rate.

1. Shooting time

Include dry solid time, it generally seems that the longer the shooting time, the more saturated the product, but we pay attention to quality, in addition to must also take full account of the production, what's more, the shooting time is too long, may cause too much smooth products

A series of difficulties such as large deformation foot of sticking die ejection, so we should fully consider the injection time of column injection molding machine when setting up, and try to reduce the injection time when meeting the quality requirements.

2. Melting time

The length depends on the rate set by the melting speed, the specification set by the condensing type, but there is one point, the length of the melting time control must be shorter than the refrigeration time.

3. Cooling time

The length of the refrigeration time immediately harms the forming cycle time time, the longer the refrigeration time, the longer the forming time, the lower the production, so we set the high pressure refrigeration time, if we can ensure that the product is fully formed, not easy to immediately damage deformation and other difficulties, the lower the set time is the better.

4. The ejection time of the mould thimble of column injection molding machine

The ejection time is generally appropriate to cooperate with the mechanical arm. The ejection stay time is generally 1.5-2 seconds when the mechanical arm is fully automatic. In automatic production and processing, it will result in the return of the die thimble

If the product falls or is stuck, and the product cannot be removed, the residence time should be kept about 5 seconds, and the ejection time can be set through the computer

5. Base pressure maintenance time

Column injection molding machine bottom pressure adjustment maintenance operators safety and grinding tools play a very big role in the whole, with the adjustment of the bottom pressure position and bottom pressure of the grinding tools, the bottom pressure maintenance time should take 1-3 seconds, the less maintenance time, the less damage may be caused.
