Abstract
Description
Technical Field
[0001] This invention relates to the field of injection molding machine technology, and in particular to a method for synchronous motion control of the template of a horizontally rotating injection molding machine platform. Background Technology
[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are mainly used to mold thermoplastic or thermosetting plastics into various shapes of plastic products using plastic molds. Injection molding machines are indispensable and essential equipment in the plastics manufacturing industry and are widely used in various fields.
[0003] In related technologies, horizontal rotary injection molding machines are a common type of injection molding machine. A horizontal rotary injection molding machine includes a fixed platen, a moving platen, and an intermediate platform. The intermediate platform is located between the fixed and moving platens, and molds are installed between the intermediate platform and both the fixed and moving platens, facilitating simultaneous injection molding using different molds. When using a horizontal rotary injection molding machine, it is generally necessary to set parameters such as pressure, flow rate, and position for both the moving platen and the intermediate platform separately. This allows for independent movement of the moving platen and the intermediate platform, enabling them to reach designated positions for subsequent injection molding.
[0004] Regarding the aforementioned technologies, the applicant has discovered the following defects: When using a horizontal rotary injection molding machine for injection molding, since the moving platen and the intermediate platform need to be set with parameters independently and moved, if the parameters are not set properly, the moving platen and the mold on the intermediate platform are prone to collide during mold opening and closing, thereby damaging the mold, causing production accidents and production stoppages. Summary of the Invention
[0005] To prevent collisions between the moving template and the intermediate platform during mold opening and closing, this invention provides a method for synchronous motion control of the platform template of a horizontal rotating injection molding machine.
[0006] In a first aspect, the present invention provides a method for synchronous motion control of a horizontal rotating injection molding machine platform template, employing the following technical solution:

[0008] Obtain the dynamic template input parameter information and platform baseline parameter information;
[0009] The platform motion parameters are determined by analyzing the input parameters from the dynamic template.
[0010] Based on the correspondence between the input parameters of the moving template, the reference parameters of the platform, the motion parameters of the platform, and the preset mold opening and closing motion scheme, the mold opening and closing motion scheme is determined and executed.

[0023] If not, the type parameter value corresponding to the value of the moving template segment will be used as the platform mold closing flow value, and the platform mold closing flow value will be used as the platform flow value.
[0024] Optionally, it also includes steps following the execution of the mold opening and closing motion scheme, as follows:
[0025] Real-time acquisition of the dynamic template location points and platform location points;
[0026] Calculate the distance between the moving template location point and the platform location point and use it as the interval distance value;
[0027] Based on the occurrence of the interval distance value and the preset spacing reference range, the platform movement speed adjustment value is analyzed and output for execution to adjust the mold opening and closing movement.
[0028] Optionally, methods for analyzing and obtaining platform movement speed adjustment values include:
[0029] Determine whether the interval distance value falls within the interval reference range;
[0030] If so, the reference position point of the moving template and the reference position point of the platform are retrieved based on the mold opening and closing status information. When the position point of the moving template is consistent with the reference position point of the moving template or the position point of the platform is consistent with the reference position point of the platform, the preset motion stop information is output.
[0031] If not, the difference between the interval distance value and the preset spacing reference value is calculated and used as the spacing deviation value;
[0032] Calculate the quotient between the spacing deviation value and the spacing reference value, and use it as the adjustment range value;

[0045] If so, output the preset warning message that the spacing is too small and the preset motion stop message;
[0046] If not, continue to calculate the difference between the interval distance value and the preset spacing reference value and use it as the spacing deviation value.
[0047] Optionally, it also includes a step following the setting of the spacing deviation adjustment value as the platform speed adjustment value, as follows:
[0048] The product between the platform speed adjustment value and the preset platform base speed value is calculated and used as the platform speed correction value;

[0050] If so, the preset platform mold opening reference adjustment value will be output and used as the platform speed adjustment value if and only if the platform speed correction value is greater than the preset platform mold opening reference speed value.
[0051] If not, then if and only if the platform speed correction value is not within the preset platform mold closing reference speed range, the platform mold closing reference adjustment value is determined based on the deviation between the platform speed correction value and the platform mold closing reference speed range and is used as the platform speed adjustment value.
[0052] In summary, the present invention has at least one of the following beneficial technical effects:
[0053] 1. By acquiring the input parameter information of the moving template and the reference parameter information of the platform, and analyzing the input parameter information of the moving template to determine the motion parameter information of the platform, and then determining and executing the corresponding mold opening and closing motion scheme based on the input parameter information of the moving template, the reference parameter information of the platform, and the motion parameter information of the platform, the operator only needs to input the parameters of the moving template and the reference parameters of the intermediate platform, simplifying the setting of the intermediate platform parameters, and making the parameters of the intermediate platform during movement adjusted according to the moving template, thereby making it less likely for the moving template and the intermediate platform to collide during mold opening and closing;
[0054] 2. By acquiring and calculating the interval distance values of the moving template position point and the platform position point in real time, and then analyzing and obtaining the platform movement speed adjustment value based on the falling of the interval distance value into the preset spacing benchmark interval, the opening and closing motion adjustment is performed. This dynamically adjusts the relative speed between the intermediate platform and the moving template, thereby making the mold less prone to collision and improving the safety of mold opening and closing. Attached Figure Description
[0055] Figure 1 This is a flowchart of a method for synchronous motion control of a horizontal rotating injection molding machine platform template according to an embodiment of this application. Detailed Implementation
[0056] To make the objectives, technical solutions, and advantages of this invention clearer, the following description is provided in conjunction with the appendix. Figure 1 The present invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.
[0057] This invention discloses a method for synchronous motion control of a horizontal rotating injection molding machine platform template.
[0058] Reference Figure 1 A method for synchronous motion control of a horizontally rotating injection molding machine platform template includes:
[0059] Step S100: Obtain the dynamic template input parameter information and platform baseline parameter information.
[0060] The moving template input parameters refer to the motion parameters set by the operator for the moving template during mold opening and closing. These parameters include pressure, flow rate, and position at each stage of mold opening and closing. The platform reference parameters refer to the pressure, flow rate, and position parameters set by the operator for the intermediate platform at the first stage of mold opening and the last stage of mold closing. Both the moving template input parameters and the platform reference parameters are obtained after pre-input by the operator.
[0061] Step S200: Analyze the input parameter information based on the dynamic template to determine the platform motion parameter information.
[0062] Among them, the platform motion parameter information refers to the parameter information of the remaining segments of the intermediate platform during the opening and closing of the mold. By analyzing the input parameter information of the moving template, the platform motion parameter information can be determined to facilitate subsequent use.
[0063] Step S300: Determine the mold opening and closing motion scheme based on the correspondence between the moving template input parameter information, platform reference parameter information, platform motion parameter information and the preset mold opening and closing motion scheme, and execute the mold opening and closing motion scheme.
[0064] The mold opening and closing motion scheme refers to the scheme used to control the movement of the moving template and the intermediate platform during mold opening and closing. This scheme is retrieved from a database storing such schemes. The scheme is determined and executed by querying the moving template's input parameters, the platform's reference parameters, and the platform's motion parameters. This simplifies the setting of the intermediate platform parameters, requiring only the operator to input the moving template's parameters and the intermediate platform's reference parameters. The intermediate platform's parameters are adjusted based on the moving template, thus minimizing the risk of collisions between the moving template and the intermediate platform during mold opening and closing.
[0065] exist Figure 1 In step S200, in order to further ensure the rationality of the platform motion parameter information, it is necessary to perform further separate analysis and calculation on the platform motion parameter information. The specific steps are explained in detail below.
[0066] The method for determining platform motion parameter information includes the following steps:
[0067] Step S210: Retrieve motion parameter information and mold opening / closing status information of the moving template based on the input parameter information of the moving template.
[0068] Among them, the moving template motion parameter information refers to the parameter information of the moving template during the opening and closing of the mold. The moving template motion parameter information is retrieved from a database that stores the moving template motion parameter information. The mold opening and closing status information refers to the status information used to indicate whether the current time is mold opening or mold closing. The mold opening and closing status information is retrieved from a database that stores the mold opening and closing status information.
[0069] Step S220: Retrieve the motion segment values, parameter type information, and type parameter values of the moving template based on the motion parameter information of the moving template.
[0070] The moving template segment value refers to the segment value at which the moving template is in motion, and this value is retrieved from a database storing these values. Parameter type information indicates the type of parameter belonging to the moving template, including pressure, flow rate, and position types. This information is retrieved from a database storing parameter type information. The type parameter value refers to the specific parameter value of the moving template corresponding to each different type, and this value is retrieved from a database storing type parameter values.
[0071] Furthermore, to improve the accuracy of the obtained category parameter values and category platform parameter values, the following steps are included after step S220: Retrieving the category number value based on the category parameter information; if and only if the category number value is inconsistent with the preset category number benchmark value, determining the deviation category information and the same category information based on the deviation between the category parameter information and the preset category benchmark information; querying and obtaining the historical parameter information of the dynamic template; retrieving the same category parameter value and the category deviation parameter value from the historical parameter information of the dynamic template based on the same category information and the deviation category information; analyzing the same category parameter value and the deviation category parameter value to form a deviation category parameter determination scheme; analyzing the category parameter value based on the deviation category parameter determination scheme to form a deviation category parameter supplementary value, and combining the deviation category parameter supplementary value with the category parameter value to form a new category parameter value.
[0072] Among them, the "Number of Categories" refers to the number of categories corresponding to the motion parameters of the dynamic template pre-input by the operator at the current time, which is retrieved from the database storing the number of categories. The "Baseline Value of the Number of Categories" refers to the baseline number of categories required for the corresponding categories of the motion parameters of the dynamic template, retrieved from the database storing the baseline values of the number of categories. The "Baseline Information of Categories" refers to the baseline category information corresponding to the motion parameters required by the dynamic template, retrieved from the database storing the baseline information of categories. The "Deviation Category Information" refers to the deviation category information when there is a deviation in the category pre-input by the operator at the current time; the "Same Category Information" refers to the category information where the category pre-input by the operator at the current time is the same as the baseline category. The "Historical Parameter Information of the Dynamic Template" refers to the parameter information input by the dynamic template at historical times, retrieved from the database storing the historical parameter information of the dynamic template. The "Same Category Parameter Value" refers to the parameter value corresponding to the same category at historical times, retrieved from the database storing the same category parameter values. The "Category Deviation Parameter Value" refers to the parameter value corresponding to the deviation category at historical times, retrieved from the database storing the category deviation parameter values. The deviation type parameter determination scheme refers to the scheme for determining the parameters corresponding to the deviation type, while the deviation type parameter supplementary value refers to the supplementary value for the parameters of the deviation type.
[0073] The parameter type information is retrieved to determine the numerical values of each type. If the numerical value of a type is inconsistent with the preset baseline value of the number of types, the parameter type information is compared with the preset baseline information. The same type is identified as the same type information, and the different type is identified as the deviation type information. The historical parameter information of the dynamic template is then queried and retrieved. The corresponding same type parameter value and deviation type parameter value are retrieved respectively. The relationship between the deviation type parameter value and the same type parameter value is analyzed to determine the deviation type parameter determination scheme. Then, the deviation type parameter determination scheme is used to analyze the type parameter value to form a deviation type parameter supplement value. This supplement value is then combined with the type parameter value to form a new type parameter value. This allows the system to automatically complete the remaining parameters when the operator's input of the parameter type is incomplete, thereby simplifying the parameter input and improving the accuracy of the obtained type parameter values and type platform parameter values.
[0074] Step S230: Analyze the type parameter values corresponding to the moving platen movement segment values based on the parameter type information and mold opening / closing status information to determine the type platform parameter values.
[0075] Among them, the type platform parameter value refers to the specific parameter value of the intermediate platform corresponding to different types. By analyzing the type parameter value corresponding to the moving platen movement segment value through parameter type information and mold opening and closing status information, the type platform parameter value is determined to facilitate subsequent use.
[0076] Step S240: Combine the platform parameter values corresponding to each type of parameter information to form platform motion parameter information.
[0077] Among them, the platform motion parameter information refers to the parameter information of the intermediate platform during the motion process. By combining the platform parameter values corresponding to each type of parameter information, the platform motion parameter information is formed. Thus, the obtained platform motion parameter information is changed and adjusted by the set motion parameters of the moving template, so that the operator does not need to set the motion parameters of the intermediate platform separately, thereby simplifying the setting of intermediate platform parameters.
[0078] In step S230, in order to further ensure the rationality of the category platform parameter values, it is necessary to perform further separate analysis and calculation on the category platform parameter values, which will be explained in detail through the following steps.
[0079] The method for determining the parameter values of a particular platform includes the following steps:
[0080] Step S231: When the parameter type information is the preset pressure type information, the type parameter value corresponding to the moving template movement segment value is used as the platform pressure value, and the platform pressure value is used as the type platform parameter value.
[0081] Among them, pressure type information refers to the type information used to indicate when the parameter type is pressure, and the pressure type information is retrieved from a database storing pressure type information. Platform pressure value refers to the parameter value corresponding to the pressure type of the intermediate platform. When the parameter type information is the preset pressure type information, the type parameter value corresponding to the moving template segment value is directly used as the platform pressure value, and the platform pressure value is used as the type platform parameter value, thereby improving the accuracy of the obtained type platform parameter value.
[0082] Step S232: When the parameter type information is the preset position type information, calculate half of the type parameter value corresponding to the value of the moving template movement segment and use it as the platform position point, and use the platform position point as the type platform parameter value.
[0083] Among them, location type information refers to the type information used to indicate when the parameter type is location, and the location type information is retrieved from a database storing location type information. Platform location point refers to the parameter value corresponding to the location type of the intermediate platform. When the parameter type information is the preset location type information, half of the type parameter value corresponding to the moving template movement segment value is calculated and used as the platform location point, and the platform location point is used as the type platform parameter value, thereby improving the accuracy of the obtained type platform parameter value.
[0084] Step S233: When the parameter type information is the preset flow type information, the type parameter value corresponding to the value of the moving template movement segment is analyzed based on the mold opening and closing status information to determine the platform flow value, and the platform flow value is used as the type platform parameter value.
[0085] Among them, flow type information refers to the type information used to indicate when the parameter type is flow, and the flow type information is retrieved from a database storing flow type information. Platform flow value refers to the parameter value corresponding to the flow type of the intermediate platform. When the parameter type information is the preset flow type information, the type parameter value corresponding to the value of the moving template movement segment is analyzed through the mold opening and closing status information, thereby determining the platform flow value and using it as the type platform parameter value to improve the accuracy of the obtained type platform parameter value.
[0086] In step S233, in order to further ensure the rationality of the platform traffic value, it is necessary to perform a further separate analysis and calculation on the platform traffic value, which will be explained in detail through the following steps.
[0087] The methods for determining platform traffic values include the following steps:
[0088] Step S2331: Determine whether the mold opening / closing status information is the preset mold opening status information. If yes, proceed to step S2332; if no, proceed to step S2333.
[0089] Among them, mold opening status information refers to the status information used to indicate whether the current time is the mold opening state. The mold opening status information is retrieved from a database that stores mold opening status information. By judging whether the mold opening and closing status information is the preset mold opening status information, it is determined whether the type parameter value needs to be processed.
[0090] Step S2332: Calculate half of the type parameter value corresponding to the value of the moving template movement segment and use it as the platform mold opening flow value, and use the platform mold opening flow value as the platform flow value.
[0091] Among them, the platform mold opening flow value refers to the flow value of the intermediate platform when the mold is opened. When the mold opening and closing status information is the preset mold opening status information, it means that the type parameter value needs to be processed at this time. Therefore, half of the type parameter value corresponding to the value of the moving template movement segment is calculated and used as the platform mold opening flow value. The platform mold opening flow value is used as the platform flow value, thereby improving the accuracy of the obtained platform flow value.
[0092] Step S2333: Use the type parameter value corresponding to the value of the moving template movement segment as the platform mold closing flow value, and use the platform mold closing flow value as the platform flow value.
[0093] Among them, the platform mold closing flow value refers to the flow value of the intermediate platform when the mold is closed. When the mold opening and closing status information is not the preset mold opening status information, it means that there is no need to process the type parameter value at this time. Therefore, the type parameter value corresponding to the value of the moving template movement segment is used as the platform mold closing flow value, and the platform mold closing flow value is used as the platform flow value, thereby improving the accuracy of the obtained platform flow value.
[0094] exist Figure 1 After step S300, in order to further ensure the rationality of the execution of the mold opening and closing motion scheme, it is necessary to perform a further separate analysis and calculation after the execution of the mold opening and closing motion scheme. This will be explained in detail through the following steps.
[0095] The steps following the execution of the mold opening and closing motion scheme include the following:
[0096] Step S400: Obtain the position points of the moving template and the platform in real time.
[0097] Among them, the moving template position point refers to the real-time position of the moving template, and the platform position point refers to the real-time position of the intermediate platform. Both the moving template position point and the platform position point are detected and obtained by a position ruler preset on the injection molding machine.
[0098] Step S500: Calculate the distance between the moving template position point and the platform position point and use it as the interval distance value.
[0099] The interval distance value refers to the real-time distance between the moving template and the intermediate platform. The distance between the moving template position point and the platform position point is calculated and used as the interval distance value for convenient subsequent use.
[0100] Step S600: Based on the occurrence of the interval distance value and the preset spacing reference range, analyze and obtain the platform movement speed adjustment value and output it for execution to adjust the opening and closing motion.
[0101] The spacing reference range refers to the reference spacing range between the moving template and the intermediate platform when no adjustment is needed. This range is retrieved from a database storing these ranges. The platform speed adjustment value is the adjustment value used to adjust the speed of the intermediate platform. The platform speed adjustment value is obtained by analyzing whether the interval distance falls within the preset spacing reference range. This value is then output and executed to adjust the proportional valve of the intermediate platform, enabling real-time adjustment during mold opening and closing. This reduces the risk of mold collisions and improves mold opening and closing safety.
[0102] In step S600, in order to further ensure the rationality of the platform speed adjustment value, it is necessary to perform a further separate analysis and calculation on the platform speed adjustment value, which will be explained in detail through the following steps.
[0103] The method for analyzing and obtaining platform movement speed adjustment values includes the following steps:
[0104] Step S610: Determine whether the interval distance value falls within the interval reference range. If yes, proceed to step S620; if no, proceed to step S630.
[0105] Specifically, by judging whether the interval distance value falls within the interval reference range, it is determined whether the intermediate platform needs to be adjusted during the mold opening and closing process.
[0106] Step S620: Based on the mold opening and closing status information, retrieve the reference position point of the moving template and the reference position point of the platform. When the position point of the moving template is consistent with the reference position point of the moving template or the position point of the platform is consistent with the reference position point of the platform, output the preset motion stop information.
[0107] The moving template reference position point refers to the reference position point that the moving template needs to reach during mold opening or closing. This reference point is retrieved from a database storing moving template reference position points. The platform reference position point refers to the preset reference position point that the platform needs to reach during mold opening or closing. This reference point is retrieved from a database storing platform reference position points. Motion stop information refers to the control information used to stop the mold opening and closing motion. This information is retrieved from a database storing motion stop information. By retrieving the moving template reference position point and the platform reference position point, when either the moving template reference position point matches the moving template reference position point or the platform reference position point matches the platform reference position point, it indicates that mold opening and closing has been completed, and the preset motion stop information is output.
[0108] Step S630: Calculate the difference between the interval distance value and the preset spacing reference value and use it as the spacing deviation value.
[0109] Among them, the spacing deviation value refers to the deviation value when there is a deviation in the spacing. When the spacing distance value does not fall within the spacing reference range, it means that the intermediate platform needs to be adjusted. Therefore, the difference between the spacing distance value and the preset spacing reference value is calculated and used as the spacing deviation value for subsequent use.
[0110] Step S640: Calculate the quotient between the spacing deviation value and the spacing reference value and use it as the adjustment range value.
[0111] The adjustment range value refers to the range value corresponding to the adjustment of the intermediate platform. It is calculated by the quotient between the spacing deviation value and the spacing reference value and used as the adjustment range value to facilitate subsequent use.
[0112] Step S650: Analyze the mold opening and closing status information and adjustment range value to determine the spacing deviation adjustment value, and use the spacing deviation adjustment value as the platform movement speed adjustment value.
[0113] Among them, the spacing deviation adjustment value refers to the adjustment value of the intermediate platform based on the spacing deviation. By analyzing the mold opening and closing status information and the adjustment range value, the spacing deviation adjustment value is determined and used as the platform movement speed adjustment value, thereby improving the accuracy of the obtained platform movement speed adjustment value.
[0114] In step S650, in order to further ensure the rationality of the spacing deviation adjustment value, it is necessary to perform a further separate analysis and calculation on the spacing deviation adjustment value, which will be explained in detail through the following steps.
[0115] The method for determining the spacing deviation adjustment value includes the following steps:
[0116] Step S651: Analyze the mold opening and closing status information and adjustment amplitude value to determine the adjustment direction information.
[0117] Among them, the adjustment direction information refers to the increase or decrease of direction information when adjusting the moving speed of the intermediate platform. The adjustment direction information is determined by analyzing the mold opening and closing status information and the adjustment range value, which facilitates subsequent use.
[0118] Step S652: When the adjustment direction information is the preset positive adjustment direction, calculate the sum of the adjustment amplitude value and the preset reference amplitude value and use it as the positive adjustment ratio value, and use the positive adjustment ratio value as the spacing deviation adjustment value.
[0119] The positive adjustment direction refers to the direction information directly adjusted (increased or decreased) when adjusting the movement speed of the intermediate platform. The positive adjustment direction is retrieved from a database storing positive adjustment directions. The reference amplitude value refers to the amplitude value corresponding to the reference movement speed of the intermediate platform during adjustment. The positive adjustment ratio value refers to the proportional adjustment value made to the movement speed of the intermediate platform after a positive adjustment. When the adjustment direction information is a preset positive adjustment direction, the sum of the adjustment amplitude value and the preset reference amplitude value is calculated and used as the positive adjustment ratio value. This positive adjustment ratio value is then used as the spacing deviation adjustment value, thereby improving the accuracy of the obtained spacing deviation adjustment value.
[0120] Step S653: When the adjustment direction information is the preset negative adjustment direction, calculate the difference between the preset reference amplitude value and the adjustment amplitude value and use it as the negative adjustment ratio value, and use the negative adjustment ratio value as the spacing deviation adjustment value.
[0121] The negative adjustment direction refers to the direction information that needs to be adjusted in the opposite direction when adjusting the movement speed of the intermediate platform, either increasing or decreasing. The negative adjustment direction is retrieved from a database storing negative adjustment directions. The negative adjustment ratio value is the proportional adjustment value that is applied to the movement speed of the intermediate platform after a negative adjustment. When the adjustment direction information is a preset negative adjustment direction, the difference between a preset reference amplitude value and the adjustment amplitude value is calculated and used as the negative adjustment ratio value. This negative adjustment ratio value is then used as the spacing deviation adjustment value, thereby improving the accuracy of the obtained spacing deviation adjustment value.
[0122] In step S651, in order to further ensure the rationality of the adjustment direction information, it is necessary to perform further separate analysis and calculation on the adjustment direction information, which will be explained in detail through the following steps.
[0123] The method for determining the adjustment direction information includes the following steps:
[0124] Step S6511: Determine the corresponding initial direction information based on the positive or negative value of the adjustment amplitude.
[0125] The initial direction information refers to the initial direction information for increasing or decreasing when adjusting the movement speed of the intermediate platform. The initial direction information is determined by the sign of the adjustment amplitude value. When the adjustment amplitude value is positive, the initial direction information is the direction of increase; when the adjustment amplitude value is negative, the initial direction information is the direction of decrease.
[0126] Step S6512: Determine whether the mold opening / closing status information is the preset mold opening status information. If yes, proceed to step S6513; if no, proceed to step S6514.
[0127] Specifically, by judging whether the mold opening and closing status information is the preset mold opening status information, it can be determined whether the initial direction information needs to be adjusted.
[0128] Step S6513: Use the initial direction information as the adjustment direction information.
[0129] When the mold opening and closing status information is the preset mold opening status information, it means that there is no need to adjust the initial direction information at this time. Therefore, the initial direction information is used as the adjustment direction information to improve the accuracy of the obtained adjustment direction information.
[0130] Step S6514: Based on the correspondence between the initial direction information and the preset direction change information, determine the direction change information corresponding to the initial direction information, and use the direction change information as the adjustment direction information.
[0131] The direction change information refers to the direction information after reversing the initial direction. This information is retrieved from a database storing direction change information. When the mold opening / closing state information is not the preset mold opening state information, it indicates that the initial direction information needs to be adjusted. Therefore, the direction change information is determined by querying the initial direction information and used as the adjustment direction information, thereby improving the accuracy of the obtained adjustment direction information.
[0132] Before step S630, in order to further ensure the rationality of the interval distance value, it is necessary to perform a further separate analysis and calculation before calculating the interval deviation value. This will be explained in detail through the following steps.
[0133] The steps preceding the calculation of the difference between the interval distance value and the preset spacing reference value, and using this difference as the spacing deviation value, include the following steps:
[0134] Step S631: Determine whether the interval distance value is less than the preset interval alarm value. If yes, proceed to step S632; if no, proceed to step S633.
[0135] The spacing alarm value refers to the spacing value at which an alarm should be triggered. This value is retrieved from a database storing these values. The system determines whether an alarm should be triggered by checking if the spacing distance is less than the preset alarm value.
[0136] Step S632: Output preset warning information for insufficient spacing and preset motion stop information.
[0137] The "too small spacing warning" information is a warning message indicating that the spacing is too small. This warning is retrieved from a database containing such warnings. The "motion stop" information is control information used to stop the movement of the moving template and intermediate platform. This information is also retrieved from a database containing motion stop information. When the spacing value is less than the preset alarm value, an alarm is triggered. Therefore, the preset "too small spacing warning" and "motion stop" information are output, allowing the operator to promptly understand the insufficient spacing and stop mold closing or opening.
[0138] Step S633: Continue with step S630.
[0139] When the interval distance value is not less than the preset interval alarm value, it means that no alarm is needed at this time, so step S630 is continued to improve the safety during mold opening and closing.
[0140] After step S650, in order to further ensure the rationality of the platform speed adjustment value, it is necessary to perform a further separate analysis and calculation on the platform speed adjustment value, which will be explained in detail through the following steps.
[0141] The steps following the setting of the spacing deviation adjustment value as the platform speed adjustment value include the following steps:
[0142] Step S661: Calculate the product between the platform speed adjustment value and the preset platform base speed value and use it as the platform speed correction value.
[0143] Among them, the platform movement speed correction value refers to the movement speed value after adjusting and correcting the movement speed of the intermediate platform. It is calculated by multiplying the platform movement speed adjustment value and the preset platform base movement speed value and using it as the platform movement speed correction value, so as to facilitate subsequent use.
[0144] Step S662: Determine whether the mold opening / closing status information is the preset mold opening status information. If yes, proceed to step S663; if no, proceed to step S664.
[0145] Specifically, by judging whether the mold opening and closing status information is the preset mold opening status information, the platform movement speed adjustment value is corrected in different ways.
[0146] Step S663: If and only if the platform speed correction value is greater than the preset platform mold opening reference speed value, output the preset platform mold opening reference adjustment value and use it as the platform speed adjustment value.
[0147] Among them, the platform mold opening reference speed value refers to the maximum speed value of the intermediate platform during mold opening, and the platform mold opening reference adjustment value refers to the reference adjustment value corresponding to the adjustment when the intermediate platform moves too fast during mold opening. When the mold opening and closing status information is the preset mold opening status information, if and only if the platform speed correction value is greater than the preset platform mold opening reference speed value, it indicates that the speed of the intermediate platform is too high. Therefore, the preset platform mold opening reference adjustment value is output and used as the platform speed adjustment value to correct the platform speed adjustment value and improve the accuracy of the obtained platform speed adjustment value.
[0148] Step S664: If and only if the platform speed correction value is not within the preset platform mold closing reference speed range, determine the platform mold closing reference adjustment value based on the deviation between the platform speed correction value and the platform mold closing reference speed range, and use it as the platform speed adjustment value.
[0149] The platform mold-closing reference speed range refers to the reference range within which the intermediate platform's speed should be during mold closing. This range is retrieved from a database storing these ranges. The platform mold-closing reference adjustment value is the reference adjustment value corresponding to the adjustment of the intermediate platform's speed during mold closing. When the mold opening / closing status information is not the preset mold opening status information, and only if the platform speed correction value is not within the preset platform mold-closing reference speed range, it indicates that the intermediate platform's speed is too high or too low. In this case, the deviation between the platform speed correction value and the platform mold-closing reference speed range is analyzed. If the platform speed correction value is less than the minimum value of the platform mold-closing reference speed range, the minimum adjustment value is used as the platform mold-closing reference adjustment value. If the platform speed correction value is greater than the maximum value of the platform mold-closing reference speed range, the maximum adjustment value is used as the platform mold-closing reference adjustment value. Finally, the platform mold-closing reference adjustment value is used as the platform speed adjustment value, thereby improving the accuracy of the obtained platform speed adjustment value.
