Three Key Points for Improving Rapid Mould Change of Injection Molding Machine

As an enterprise, the efficiency of rapid die change of injection moulding machine directly affects profits. Here are three main points of rapid die change:

I. Distinguishing between inside and outside

Distinguishing between inside and outside means dividing the die changing operation of punch and injection moulding machine into internal preparation operation, adjusting preparation operation and external preparation operation.

The so-called internal preparation work refers to the preparation work that must stop the punch or injection machine, such as the disassembly and installation of the mould. Adjustment of equipment operation refers to the operation that the punch and injection moulds are installed and finished to the output of qualified products. External preparatory work refers to the preparatory work that can be done in the operation of the machine, such as the repair of the punch die, the preparation of tools and materials used for changing the mould of the injection moulding machine, etc.

2. From inside to outside

Turning from inside to outside means turning internal preparation into external preparation as far as possible.

After improvement, the preparatory work that can be started only when the machine becomes the work that can be completed in advance in the operation of the machine. For example, in the injection molding process of plastic injection moulding machine, the metal mould can be preheated in advance when the mould is to be produced next time. It is not necessary to wait until the equipment is installed before the preheating operation is done. It can be produced after replacing the mould, thus saving the heating operation time of the metal mould.

3. Optimizing Internal and External Conditions

To optimize the internal and external preparation is to shorten the time of internal preparation and external preparation.

Internal preparation work is the work that must stop the equipment and exchange the mould quickly in the shortest time.

Large-scale moulds can use trolley as the working platform for rapid die change. Punch and injection moulds can move and access quickly during rapid die change operation. There is a moving track under the trolley, and the mould can be moved directly to the working platform to change the mould of the injection moulding machine. Fast positioning of positioning pin is designed to fix the die with fast chuck, which can change the die quickly and easily, save the time of crane hoisting operation, and improve the stability and safety of the die changing operation.
