The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments.

Example 1

As shown in fig. 1 to 3, the method for freely programming the motion of an injection molding machine according to the present invention comprises the steps of:

the injection molding machine operation flow chart can display the current operation action and the action time of the action in the action flow chart in different colors.

wherein, parameters that can be set include: process parameters, action parameters and execution conditions.

Wherein the action parameters include the type of input and output data used by the action, which set of systems the action belongs to, whether the systems merge or flow separation, etc.

The execution conditions comprise a digital quantity signal input value, an analog quantity input value and action time, and the three execution conditions can be combined with logic of OR.

When the user sets the parameters of the corresponding actions, the same parameters can be set for the actions of the same type in a duplicated mode, and when the user sets the parameters of the corresponding actions, the parameters of the actions can be set in an imported mode, and all the parameters on the flow chart can be stored in the background or exported to the storage device.

For example, after setting the parameters of injection a, when setting the parameters of injection B, copying may be selected to copy all the parameters of injection a to injection B, and then fine-tuning some of the parameters may be performed.

In the parameter input, all the stored parameters may be selected, or only the mold parameters, only the machine parameters, all the parameters of a single action, or only the machine parameters/mold parameters of a single action may be selected.

The setting of the injection molding machine main body circulation flow in the step S1 comprises the following steps:

s11, acquiring setting information of a user on the whole action logic of the injection molding machine.

Specifically, step S11 includes:

s111, acquiring injection molding machine action column information which is set by a user and is executed in sequence.

In the operation of the operation flow of the injection molding machine, after all the operations in one row are completely executed, all the operations in the next row are executed, and the operations are executed again from the first row until the operations are executed to the row with the end options.

In addition, the user can directly set the action row and the action column data, the action logic of the row A and the row B is displayed after the setting is finished, and the user can set detailed action logic information at the corresponding position of the row A and the row B.

S12, acquiring detailed action logic information edited and formed by a user in the overall action logic.

The actions which can be specifically set by the user in the corresponding position comprise injection, storage, ejection and retraction, mold opening, mold closing, neutron advance, neutron retraction, mold supporting advance, mold supporting retraction and the like.

S13, acquiring the setting of the combined action logic by a user.

The user can logically combine two or more preset actions into a combined action and set the combined action in the action row and the action column, or can nest the combined action in the combined action.

Referring to fig. 4 to 6, taking an injection molding process of a two-color machine in an injection molding machine as an example, the working principle of the invention is described as follows:

the concrete process of the injection molding action of the double-color machine is that after entering automation, closing the mold, and after closing the mold to the bottom, carrying out the AB injection storage injection and ejection action which are mutually independent; after the injection and the ejection are finished, opening the die; after the die is opened to the bottom, simultaneously executing a die supporting A and a die supporting B; after the supporting dies A and B are finished, executing a die rotating action; after the die rotation is finished, the recycling time is started, and after the recycling is finished, the next cycle is started.

Before the injection molding machine is started, the user needs to set the injection molding east flow process, and first, the user needs to open a free action editing interface to set the overall action logic and the detailed action logic of the injection molding machine.

As shown in fig. 4, the number of rows of the most simultaneous actions required at present is set to 2, the number of columns of actions is set to 7, that is, the overall action logic of the injection molding machine is set to 2 rows and 7 columns, and action options of 2 rows and 7 columns are displayed in the interface for selection.

The detailed action logic is then set, i.e. the first row of action sequences 1 is the off-mode, the first row of action sequences 2 is the combined action 1, the second row of action sequences 2 is the combined action 2, the first row of action sequences 3 is the open-mode, the first row of action sequences 4 is the combined action 3, the second row of action sequences 4 is the combined action 4, the first row of action sequences 5 is the rotary-mode, the first row of action sequences 6 is the recirculation start, and the first row of action sequences 7 is the end.

Then, the combination operation set therein is further set, as shown in fig. 5, and the combination operation 1 is selected in the combination operation setting screen, and specifically set as follows: the action sequence 1 is injection A, the action sequence 2 is storage A, and the action sequence 3 is injection A.

Meanwhile, other combined actions are set according to the same method, for example, the combined action 2 is sequentially injection B, storage B and ejection B; the combination action 3 sequentially comprises the steps of feeding a supporting die A and withdrawing the supporting die A; the combination action 4 is that the supporting die B advances and the supporting die B retreats in sequence.

The user completes the setting of the action logic, and then generates a corresponding injection molding machine action flow chart according to the injection molding machine main body circulation flow set by the user, and the injection molding machine action flow chart is displayed on the interface as shown in fig. 6.

Then, the user can click on the injection A icon on the action flow chart, enter a parameter setting picture of the injection A, set the injection A to use the simulation ruler 1, automatically correspond the storage and injection A to the simulation ruler 1, set technological parameters, other parameters and the like of the injection A.

Clicking the same-A button in the injection B picture to make all B action parameters the same as A, and then finely adjusting different parameters of specific A and B. And the other actions are set quickly in the same way.

The user can also import the preset parameters into the machine by means of importing the parameters, and then fine adjustment is carried out according to the requirements.

Finally, the user can start the injection molding machine, and the host machine of the injection molding machine can read the flow setting data value on the panel after finishing the action editing.

And calling all action flow program blocks corresponding to all actions in the first row at the same time when the action is automatic until all the action flow program blocks executed in the first row are executed, and then calling all action flow program blocks in the next row. And when the action reaches the end of setting the data value of the panel, the action flow block is called again from the first row.

If the called actions are combined actions, reading the data value set by the combined actions, and calling each action in turn until all actions in the combined actions are executed, and then, judging that the combined actions are executed.

The function of each action in the present invention is written using a separate block and the block is divided into a material creation block and an action flow block for the action.

When the action editing selects the mode closing action, the program block created by the action data is called. Corresponding materials are created in the program blocks for creating the materials, and initialization programs for calling some basic functions are also provided.

Upon automatic action, such as a mode-off action, an action flow block is invoked. The action flow block includes execution of the entire mode closing action. When the start condition is satisfied, the mode closing operation is entered, the number of segments is switched according to the position of the associated ruler AI or the set DI signal logic, and the set DO and AO are output at each segment position. And when the set ending condition or the ending condition of the block mark is met, for example, the closing end position of the die and the closing end signal of the DI point are ON, the execution of the block is finished.

In addition, the invention also forms a protection sequence rule according to the set flow in the program, and when the action logic does not meet the set protection logic, an alarm is generated and the action is limited.

The invention generates the operation flow of the injection molding machine through the free combination of the action program blocks, can meet the requirements of various special action flows, and can directly change the operation on the panel when the special requirements exist, thereby saving the time for waiting for program modification.

The invention can use the same program on various machine types, increases the universality of the program, is convenient for program version management, and reduces the time and money cost required by later maintenance; and the current automatic action flow can be clearly displayed on the operation panel, so that a user can intuitively know which action the action flow goes to and which actions the machine is about to perform.

The specific embodiments described herein are offered by way of example only to illustrate the spirit of the invention.
