Customer backgrounQiaotian Automatic Mould zChange | Long mould change time and low efficiency? The automatic mould change system solves it with one click!A large injection moulding products and mould sales enterprise, focusing on the production of complex plastic products such as automotive interior parts. There are 25 injection moulding machines from 1000T to 4000T in the injection workshop, and frequent mould change is an inevitable demand for producing different injection moulded parts and trial moulds. At present, the customer is facing pain points such as the mould change time of a single injection moulding machine is as long as 2 hours, and it is easy to make mistakes when manually plugging and unplugging electrical and plumbing fittings, and it is difficult to realize automation of the mould change.

Based on this, Qiaotian Intelligence provides a total solution for automatic mould change, which is based on the following four perspectives to improve the efficiency of mould change, reduce the operation risk, and ensure the precision and stability of mould installation.

Shorten the mould change time: improve the comprehensive efficiency by more than 70

Hashida intelligent automatic mould changing system consists of magnetic mould changing system and industrial connector docking combination module, covering dynamic board, static board, control system and HMI control panel. Magnetic mould changing system adopts electronically controlled permanent magnet technology, through electromagnets and permanent magnets, to achieve 3-8 seconds (depending on the tonnage of the injection moulding machine) of demagnetisation time, and quickly complete the installation and uninstallation of the mould on the back plate of the injection moulding machine. Industrial connector pairs of plug combination module consists of pairs of plug boards and standardised utility joints, one side is fixed to the mould, the other side is fixed to the injection moulding machine, through the automatic insertion and removal of mould connectors to achieve fast and error-free connection, large-scale injection moulding machine moulds dozens of connectors need to be automatically inserted and removed only once. The mould change time of a single injection moulding machine is shortened from 2 hours to less than 30 minutes, and the comprehensive efficiency is improved by more than 70%.  

The picture shows a case of 1400T automatic mould change for a customer in the injection moulding industry.

Avoiding the risk of mould change: improving safety performance

The magnetic mould change system in Hashida's automatic mould change system adopts an all-steel structure design, and the magnetic unit is mounted on the back to ensure the strength and sealing of the magnetic plate, which significantly prolongs its service life. The system guides the magnetic circuit by reasonably allocating the size chain, with large magnetic suction force per unit area, sufficient number of magnetic poles and strong suction force. Each pole is equipped with an induction coil to detect changes in magnetic flux in real time and accurately monitor the magnetic suction force. When there is a cavity inside the mould, the system can display the suction force and safety factor in real time to assist in judging the safety of use. The industrial connector adopts the design of pair-plug combination module, realising a high degree of integration of electricity, liquid and gas, with a service life of more than 100,000 times, which effectively avoids plugging and unplugging errors caused by many connectors.

Enhancing system stability: increased reliability

The magnetic mould changing system in Qiaotian's automatic mould changing system adopts modular unitised magnetic pole design, where individual poles are installed on the magnetic plate after glue filling, and the connection between poles is then filled with glue, eliminating the risk of short circuit. The control system has strong robustness, the main control board, the excitation board, the magnetic flux detection board, the power supply board are modular design and control, through the CAN bus communication, strong stability. The excitation channel is individually controlled and monitored for protection, with sensitive monitoring and strong anti-interference capability. Peak current can be monitored during the magnetisation process to prevent abnormalities caused by short-circuit, leakage and other circuit faults, and once an abnormality occurs, the magnetisation is stopped to protect the system. Industrial connector pairs of plug-in combination module with low impedance characteristics to meet the more than 100,000 times the life of plugging and unplugging, the circuit breaks the medium does not drip from the end of the connector, to maintain the cleanliness and safety of the production plant.

Optimise the cost of mould change, recover the investment of automatic mould change system within half a year.

The installation of Qiaotian's automatic mould change system significantly shortens project time and reduces safety risks during mould change. The overall start-up rate of the injection moulding machine is greatly increased, and more injection moulded parts can be produced in the same time. The cost of the automatic mould change system was recovered within half a year.

Up to now, within half a year of its launch, Qiaotian's automatic mould changing system has been applied in the industry's first-class OEMs, machinery manufacturers, mould factories, electronic components and other enterprises, and has successively shipped dozens of sets of magnetic mould changing systems of 3300T, 2400T, 1400T, 800T, and 300T sizes and tonnages, as well as nearly one hundred sets of pneumatic, electric, and hydraulic integrated industrial connector plug-in modules. As an automatic mould change solution provider, Qiaotian Intelligence is committed to providing safe, efficient and reliable automatic mould change solutions for customers in the plastic injection moulding industry.
