Abstract

A control system and a control method of manufacturing injection molding products are provided. The control system includes an injection molding machine, an information input interface, a computing server and a data conversion device. At first, product information is inputted through the information input interface. The product information is transmitted to the computing server, and then the computing server determines injection molding parameters according to the product information. The injection molding parameters are transmitted to the information input interface. After data conversion through the data conversion device, the injection molding machine is controlled to manufacture the injection molding products according to the converted injection molding parameters.

First claim

What is claimed is:

an injection molding machine, configured to manufacture the injection molding products;
an information input interface, configured to receive and transmit product information of the injection molding products;
a computing server, in communication with the information input interface, configured to receive the product information transmitted from the information input interface, determine a plurality of injection molding parameters according to the product information, and transmit the injection molding parameters to the information input interface;
a model database;
a trouble-shooting database;
a case database of injection molding parameters and associated results, wherein said injection molding parameters comprise melting temperature, a mold temperature, a filling time, an injection velocity, an injection pressure, a packing pressure, a packing time and a cooling time;
a user interface configured to display 4 intersected slopes based on said eight injection molding parameters, wherein an area defined by the 4 intersected slopes indicates optimum ranges for said injection molding parameters, wherein the user interface provides a capability to perform an adjustment of one or more injection molding parameters; and
a data conversion device, in communication with the injection molding machine and the information input interface, configured to receive and convert the injection molding parameters from the information input interface, the converted injection molding parameters having a data format acceptable by the injection molding machine which is controlled according to the converted injection molding parameters.

2. The control system according to claim 1 , wherein the information input interface is a server or a computer.

3. The control system according to claim 1 , wherein the computing server is a cloud server or a workstation.

4. The control system according to claim 1 , wherein the computing server comprises:

a calculation unit, in communication with the selection unit, configured to calculate the injection molding parameters according to the selected data.

5. The control system according to claim 4 , wherein the computing server further comprises:
a defect identification unit, in communication with the case database, the trouble-shooting database and the calculation unit, configured to receive data from the case database and/or the trouble-shooting database to enable the calculation unit to adjust the calculated injection molding parameters according to the received data.

6. The control system according to claim 1 , wherein the control system further comprises a portable device in communication with the information input interface and the computing server, configured to receive and show the injection molding parameters on a display of the portable device, the portable device providing an input window, the injection molding parameters received from the computing server being adjusted through the input window and then transmitted to the information input interface.

7. The control system according to claim 6 , wherein the portable device is a tablet computer, a notebook computer, a smart communication apparatus or a personal digital assistant.

8. The control system according to claim 1 , wherein the control system further comprises a monitor module in communication with the injection molding machine and the information input interface, the monitor module monitoring the injection molding machine and actuating the information input interface to adjust the injection molding parameters.

9. The control system according to claim 1 , wherein the case database further comprises ordered collections of parameter settings and associated results, the parameter settings including a melting temperature, a mold temperature, a filling time, an injection velocity, an injection pressure, a packing pressure, a packing time and a cooling time, and the associated results including pass/fail results including codes for particular known defects.

10. The control system according to claim 9 , wherein the user interface is able to display pairs of parameters on a two-dimensional plot, with individual points labeled according to the results obtained with the combinations of parameters shown on the x-axis and y-axis.

11. The control system according to claim 1 , further comprising a technical support unit linking a user through the information input interface to an online interactive service, wherein the online interactive service puts the user into communication with at least one expert skilled in the use of the control system.

12. The control system according to claim 1 , wherein the adjustment of one or more injection molding parameters is based on environmental condition.
