When the requirements for mold changing time are very strict, a mold changing trolley can be used to change molds on both sides of the punch press, which will greatly shorten the mold changing time and achieve high automation. The mold changing trolley not only improves the efficiency of mold changing, but also increases the return on investment.
The mold changing trolley system can be divided into the following three types according to the workstation:
1. Single station mold changing trolley
The mold changing trolley loads and unloads the mold manually or through a power moving mechanism based on the weight of the mold. When changing the mold, first pull the mold out of the machine, move it away from the mold changing trolley with a crane or forklift, then place the new mold on the roller of the mold changing trolley, and then push the new mold into the machine
The fixture and roller system of the molding machine are used in combination. The single station mold changing trolley can also switch molds in both directions, serving two machines and improving the return on investment.
2. Dual station mold changing trolley
Faster than single station mold changing, the mold can be preheated on the mold changing trolley first, saving a lot of time The mold changing trolley loads and unloads the mold manually or through a power moving mechanism based on the weight of the mold. When changing the mold, pull out the mold from the machine and place it on the empty space of the trolley, then reposition the trolley and
In the new mold pushing machine at another workstation. The fixture and roller system of the mold changing trolley and forming machine are used in combination The dual station mold changing trolley can also switch molds in both directions, serving two machines and improving the return on investment
3. Multi station mold changing trolley
For small-scale production using only a limited number of molds, a multi station (including 3 or more molds) mold changing trolley is used. The mold can be stored and preheated on the mold changing trolley, saving a lot of time and space. The mold changing trolley loads and unloads the mold manually or through a power moving mechanism based on the weight of the mold. When changing the mold, pull out the mold from the machine and place it on the empty space of the trolley. Then, reposition the trolley and push the new mold from the required workstation into the machine. The fixture and roller system of the mold changing trolley and forming machine are used in combination.
The multi station mold changing trolley can also perform bi-directional mold changing Serve 2 machines to improve investment return rate.
The mold changing trolley system can effectively solve the mold changing operation of large molds weighing 3 to 15 tons, and is widely used in the manufacturing industry of large plastic injection parts such as automotive sheet metal, automotive bumpers, car lights, refrigerators, washing machines, and large toys.
