If the neutron is selected in the switch control mode, the neutron advancing action is finished when the program detects a neutron advancing in-place signal; when a user wants a certain neutron oil cylinder in the injection mold to act in the core pulling direction, when the injection molding machine controller program executes the retreating action of the neutrons, the program can output a signal of the retreating of the neutrons, the valve for controlling the retreating of the neutrons can suck the neutrons, and the neutrons act in the retreating direction. If the neutron is selected in the switch control mode, the neutron retreating action is finished when the program detects a neutron retreating in-place signal.
The control mode of the neutron is a switch control mode, and the mark for the neutron in-place of the related safety chain is a neutron arrival signal; the flag for neutron back-to-bit for the associated safety chain is the read neutron back-to-bit signal.
In the neutron control method, the neutron retreating signal corresponds to the neutron retreating action, and the neutron advancing signal corresponds to the neutron advancing action; in the actual working process, the actual action of neutrons is often opposite to the advancing and retreating directions required by customers, such as the situations that oil pipes of an oil cylinder and an injection molding machine are reversely connected; the method for solving the problem is as follows: 1. debugging personnel need to replace a neutron oil pipe and an oil cylinder joint on the injection molding machine so as to meet the requirements of customers; 2. and adjusting an electric appliance, and switching a neutron valve and an in-place switch signal. However, the actual operation process of the two methods is complex, time-consuming and labor-consuming, and once the operation is careless, the plugging and unplugging of the high-pressure oil pipe can cause personal injury or cause oil leakage at the joint of the oil pipe; moreover, the exchange of neutron signals may cause signal abnormality, which affects the normal operation of the injection molding machine and other injection molds.
In order to overcome the above disadvantages of the conventional injection molding machine neutron action control method, a control method which is simple in operation, high in safety and capable of reversely controlling the neutron action needs to be designed.

The invention solves the technical problem by adopting the technical scheme that a neutron action reverse control method of an injection molding machine is provided, which comprises the following steps:
s1, fixing the injection mold on an injection molding machine, and connecting an oil cylinder which controls the advancing and retreating of neutrons on the injection mold with a hydraulic system of the injection molding machine by using an oil pipe;
s2, switching a control panel of the injection molding machine to a neutron function setting interface, and selecting a 'use' option in neutron reverse setting;
s3, enabling the injection molding machine controller program to execute a neutron advancing action, controlling a neutron retreating valve to absorb oil, and driving neutrons to retreat by an oil cylinder; or, the injection molding machine controller program executes the neutron retreating action, the valve for controlling the neutron advance generates oil absorption, and the oil cylinder drives the neutron advance.
Further, in S3, the action of neutron withdrawing is defined as neutron core pulling; in the definition of S3, the action of neutron advancement is a neutron core insert;
when the injection molding machine controller program executes the neutron advancing action, the program can output a neutron retreating signal to perform neutron core pulling; when the injection molding machine controller program executes the neutron retreating action, the program can output a neutron-in signal and a neutron inserting core.
Furthermore, the termination of the advancing action and the termination of the retreating action of the neutrons are controlled by a travel switch;
when the injection molding machine receives a neutron in-place signal, triggering one of the travel switches to end the neutron deactuation action; when the injection molding machine receives the neutron in-place returning signal, another travel switch is triggered to finish the neutron advancing action.
Furthermore, the advancing action and the stopping action of the neutrons are controlled by time;
when the neutron precession action signal of the injection molding machine is sent out for a preset time, the neutron retreating action is finished; and when the neutron retrogression action signal of the injection molding machine is sent out for the preset time, the neutron advancement action is finished.
Further, the neutron reversal setting also comprises a 'no' option; when the "no" option is selected, the neutron reversal function is not used.
Furthermore, the number of the neutrons is one or more, and each neutron is provided with a neutron reverse arrangement corresponding to the neutron; the neutrons between the neutrons are reversely arranged without mutual influence.
Furthermore, the neutron function setting interface also comprises a neutron linkage setting and a neutron maintaining setting; and the neutron linkage setting and the neutron maintaining setting at least comprise two options of 'use' and 'no'.
Further, when the neutron linkage setting selects a 'use' option, the neutrons retreat while the injection mold is opened; when the neutron hold setting selects the "use" option, the hydraulic system of the injection molding machine continues to provide pressure to the neutrons.
Further, the injection molding machine has a storage module; the parameter information of the injection mold is stored in the storage module, and information related to neutron reverse setting is stored in the storage module; the reverse neutron setting between different injection mold does not influence each other.
Further, in S1, the number of oil pipes connected to each neutron of the injection mold is two, one oil pipe is used for oil feeding during the neutron advancing action, and the other oil pipe is used for oil feeding during the neutron retreating action.
Compared with the prior art, the invention has at least the following beneficial effects:
1. according to the injection molding machine, a neutron reverse control function is added in the injection molding machine, each neutron has the reverse control function, when an oil pipe is reversely connected or other special requirements are met, the neutron reverse is directly arranged on an operation panel of the injection molding machine through one key, so that neutrons retreat when a controller program of the injection molding machine executes neutron advancing action; when the injection machine controller program executes the neutron retreating action, neutrons advance. The oil pipe with high plugging pressure is not needed to be plugged, and the joint is replaced; the neutron valve and the in-place switch signal are switched without adjusting an electric appliance; avoiding causing damage to operators or economic loss, and storing information whether each set of injection mold adopts the neutron reverse control function in a storage module of the injection molding machine by combining the information of the injection mold; the neutron reverse control function information between the injection molds cannot influence each other, so that the neutron control method of the injection molding machine is disordered. When the neutron reverse setting selects the 'NO' option in the neutron function setting interface of the injection molding machine control panel, the reverse control function is not started, and like the control method of the neutrons in the existing injection molding machine, the neutron retreat signal corresponds to the neutron retreat action, and the neutron advance signal corresponds to the neutron advance action.
2. According to the invention, the neutron function setting interface also comprises a neutron linkage and a neutron keeping setting, when the neutron linkage function is used, the neutron can retreat while the mold is opened, so that the mold opening time is saved, and the injection molding period is shortened; when the neutron holding function is used, the neutron can be inserted into the core, and the hydraulic system continues to provide pressure for the neutron, namely pressure maintaining, so that the neutron is prevented from retreating or the compactness of the interior of a product is maintained.

Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
For some plastic products with relatively complex structures, the plastic products cannot be molded by a flat plate mold alone, for example, the side holes, the side grooves and other structures are molded by arranging a sliding block mechanism on an injection mold; the movement of the sliding block is divided into an inclined guide post drive mode and an oil cylinder drive mode, and compared with the inclined guide post drive mode, the oil cylinder drive mode has the advantages of stable action, large core pulling force, difficulty in clamping the sliding block and the like, and the utilization rate is high.
As shown in fig. 1, a common control method for the neutron advance action includes:
when the injection molding machine controls the program to execute the advancing action of neutrons, the program outputs a neutron advancing signal, so that a valve for controlling the neutron advancing is sucked, the oil cylinder is extended, the neutrons move towards the advancing direction, namely the core inserting direction, when the neutrons are advanced in place, the oil cylinder triggers a forward stroke switch, the program detects the neutron advancing in-place signal, the valve for controlling the neutron advancing no longer sucks the oil, and the neutrons finish moving towards the core inserting direction.
As shown in fig. 2, a common control method for the neutron annealing operation includes:
when the injection molding machine controls the program to execute the retreating action of the neutrons, the program outputs a signal of neutron retreating, a valve for controlling the neutron retreating can suck, the oil cylinder contracts, the neutrons move towards the retreating direction, namely, the core pulling direction, when the neutrons retreat in place, the oil cylinder triggers the rear travel switch, the program detects a signal that the neutrons retreat in place, the valve for controlling the neutron retreating does not suck the oil any more, and the neutrons finish moving towards the core pulling direction.
Based on the existing common control method of the neutron advancing action and the neutron retreating action, in the actual use process, because the advancing and retreating joints of the oil cylinder are not obviously different, the conditions that an oil pipe for controlling the oil cylinder to advance and an oil pipe for controlling the oil cylinder to retreat are reversely connected with an injection molding machine often exist, at the moment, the oil pipe needs to be pulled out, replaced and reconnected, the hydraulic oil pressure in a hydraulic system of the injection molding machine is high, and the plugging and unplugging of a high-pressure oil pipe easily causes personal injury.
As shown in fig. 3-5, the neutron action reverse control method of the injection molding machine of the present invention comprises:
s1, fixing the injection mold on an injection molding machine, and connecting an oil cylinder which controls the advancing and retreating of neutrons on the injection mold with a hydraulic system of the injection molding machine by using an oil pipe; specifically, the number of oil pipes connected to each neutron of the injection mold is generally two, one oil pipe is used for oil feeding when the neutron advances, and the other oil pipe is used for oil feeding when the neutron retreats. In the scheme, the situation that two oil pipes are reversely connected when the hydraulic systems of the oil cylinder and the injection molding machine are connected is mainly aimed at.
S2, switching a control panel of the injection molding machine to a neutron function setting interface, and selecting a 'use' option in neutron reverse setting; specifically, the neutron reversal setting also includes a "no" option; when the "no" option is selected, the neutron reversal function is not used, that is, when the "no" option is selected in the neutron reversal setting, the method of controlling neutron advance and retreat of the injection molding machine is the same as the existing neutron control method.
S3, enabling the injection molding machine controller program to execute a neutron advancing action, controlling a neutron retreating valve to absorb oil, and driving neutrons to retreat by an oil cylinder; or, the injection molding machine controller program executes the neutron retreating action, the valve for controlling the neutron advance generates oil absorption, and the oil cylinder drives the neutron advance.
Preferably, in S3, the action of neutron withdrawing is neutron core pulling; in the definition of S3, the action of neutron advancement is a neutron core insert; before injection molding of an injection mold, a neutron needs to be inserted into a core to enable the neutron to return to an initial position, after injection molding is completed, the neutron needs to be pulled out, then a plastic product is ejected, and the product is prevented from being damaged by pulling when the plastic product is ejected out, wherein the neutron is pulled out before or during or after opening the mold of the injection mold. In this scheme, neutron lock pin and neutron are loosed core and are driven through the flexible of hydro-cylinder.
Because the neutron reversing function is used, when the injection molding machine controller program executes neutron advancing action, the injection molding machine program can output a neutron retreating signal to perform neutron core pulling; when the injection molding machine controller program executes the neutron retreating action, the injection molding machine program can output a neutron-in signal and a neutron inserting core.
Wherein, the end positions of the advancing action and the retreating action of the neutrons are controlled by a travel switch; a front travel switch is arranged on the oil cylinder to control the termination position of the neutron core insert, and a rear travel switch is arranged on the oil cylinder to control the termination position of the neutron core insert; when the injection molding machine receives a neutron arrival position signal, one of the travel switches is triggered to finish the neutron retreating action; when the injection molding machine receives a neutron in-place returning signal, triggering another travel switch to finish the neutron precession action; the relative positions of the front travel switch and the rear travel switch can be adjusted to control the end positions of the neutron advancement and the neutron recession. The neutron advancing and retreating is controlled by a travel switch, the position is accurate, and the transmitted information is sensitive.
Another control method for stopping the advancing action and the retreating action of the neutrons is through time control: when the neutron precession action signal of the injection molding machine is sent out for a preset time, the neutron retreating action is finished; and when the neutron retrogression action signal of the injection molding machine is sent out for the preset time, the neutron advancement action is finished. Specifically, the neutron movement speed is constant, so that the movement distance of neutrons can be calculated through time, and according to a formula, the movement distance S is the movement speed V × the preset time T, the preset time T is controlled to be different values, different values of the movement distance S are controlled, and the core pulling or core inserting distance desired by a user is reached.
Preferably, as shown in fig. 6, in the present scheme, the number of neutrons is one or more, and each neutron is configured with a neutron reverse arrangement corresponding to the neutron; when a plurality of neutrons are present, the neutron reversal settings between the neutrons do not affect each other. Namely, the neutron reverse functions of each neutron are mutually independent, and the use of each neutron does not influence the reverse functions of other neutrons so as to avoid information interference. Because some injection molding products with complex structures usually need a plurality of neutrons to be formed, a plurality of neutron reversal functions are configured on the same injection molding machine so as to meet the requirements of the injection molding products.
And the injection molding machine has a storage module, the parameter information of the injection molds is stored in the storage module, and the information related to the neutron reversal setting is also stored in the storage module, in the actual use process, in order to distinguish different injection molds, the injection molds are numbered aiming at different injection molds, each injection mold is enabled to have the corresponding ID, each ID information is corresponding to the injection parameters related to the ID information, such as injection time, injection pressure, injection temperature, dwell time, dwell pressure, mold remaining time, ejection time and other parameters, wherein, aiming at different injection molds, whether the neutron reversal function is used or not is also stored in the storage module as the parameter information corresponding to the mold ID, thus, because of the different molds, the ID information is different, the neutron reversal function information of the mold itself can not influence other neutrons, the injection molding machine is beneficial to the management and control of different neutrons of different molds.
As shown in fig. 6, the neutron function setting interface further includes a neutron linkage setting and a neutron maintenance setting; and the neutron linkage setting and the neutron maintaining setting at least comprise two options of 'use' and 'no'. When the neutron linkage setting selects the 'use' option, the neutron retreats when the injection mold is opened, namely the injection mold opens the mold while the neutron retreats, and the neutron retreats after the mold is opened completely; or the neutron linkage function can save the die opening or core pulling time and further shorten the injection molding period; when the neutron keeps setting up selection "use" option, the hydraulic system of injection molding machine continues to provide pressure to the neutron, promptly when to injection moulding in the injection mould after the molten plastics, still continues to provide a pressure for the neutron, is equivalent to the pressurize power among the injection moulding, guarantees that product inner structure is closely knit, prevents the condition such as the product is loose, the neutron is retreated. Preferably, each neutron is also provided with the 'linkage setting' and 'holding setting' functions, and the 'linkage setting' and 'holding setting' functions between different neutrons are not affected by each other, and do not cause signal interference to other neutrons.
The injection molding machine neutron action reverse control method can effectively ensure the personal safety of operators, is convenient to operate, and saves time and labor; and moreover, neutron signals do not need to be exchanged, and the condition of disordered neutron signal management of the injection molding machine can be avoided.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
