Issues That Should Be Paid Attention To When Installing The Rotomolding Mold To The Rotomolding Machine

Different types of rotational molding machines have different mold bracket structures. Common mold brackets include square frame type and disc spider web type. The mold bracket of the swing machine is different from that of the large direct-fired rotational molding machine. It is a structure similar to that of a concrete mixer. What we are going to talk about is the installation method of rotational molding on a small general rotational molding machine. Whether the rotational molding mold installed on the mold bracket is appropriate and reasonable directly affects the quality of the rotational molding products. This is also an important part of the rotational molding process that cannot be ignored.

1. Selection of rotomolding mold. On the same rotational molding machine, if conditions permit, choose the same type of mold. If you want to produce other products of different categories at the same time, when selecting the rotational molding mold, strive to install the molds that are similar in size and the weight difference should not be too great. The thickness requirements are basically the same. This is to avoid product aging and degradation or residual plastic powder, because different rotational molding molds require different processing cycles.

2. The installation distance of rotational molding molds. How many molds should be installed on a mold bracket should be calculated well. There should be enough distance between the molds to avoid blocking each other, which is conducive to the conduction of hot air and also facilitates mold opening and closing.

3. The balance of the mold bracket. This point must be noted. If the bracket is heavy on one side and light on the other, the rotation of the rotomolding machine will be affected. At least it will cause uneven thickness of the product. In serious cases, it will damage the rotomolding machine.

4. Pay attention to the diameter of the oven of the rotational molding machine, and calculate the rotation range when installing the mold, otherwise it will bring adverse consequences.

5. When installing the rotomolding mold, you must consider both the firmness and the speed of installation and disassembly.
