[0007] The objective of this invention can be achieved through the following technical solutions:

[0009] Step 1: Used to obtain injection data of the molten liquid in the mold;

[0010] The injection molding data includes temperature and pressure performance values.

[0011] Step 2: Calculate the injection molding stability coefficient based on the temperature and pressure performance values;

[0012] Step 3: Based on the injection molding stability coefficient, and by comparing and analyzing it with the threshold, the injection molding stability signal is obtained; wherein, the injection molding stability signal includes the superior injection molding stability signal and the poor injection molding stability signal;

[0024] As a further aspect of the present invention: in step 3, if the injection molding stability coefficient XZw is less than the injection molding stability coefficient threshold XZwy1, then an injection molding stability superior signal is generated.

[0025] If the injection molding stability coefficient XZw is greater than or equal to the injection molding stability coefficient threshold XZwy1, then an injection molding stability difference signal is generated.

[0026] As a further aspect of the present invention: In step 4, when the injection molding stability difference signal is obtained, a monitoring period T is set, the duration of each occurrence of the injection molding stability difference signal within the monitoring period T is obtained, and the duration of each occurrence of the injection molding stability difference signal is summed to obtain the total value of the injection molding abnormal stability time ZCY.

[0027] At the same time, the time interval between adjacent occurrences of injection molding stability difference signals is obtained, and the time intervals between adjacent occurrences of injection molding stability difference signals are summed to obtain the injection molding abnormal stability time fluctuation value ZBY.

[0030] As a further aspect of the present invention: in step 1, if the difference in coefficients during abnormal periods is less than the first threshold value of the difference in coefficients during abnormal periods, then a first monitoring period T / 2 is generated;

[0031] If the first threshold of the abnormal period coefficient difference is less than or equal to the second threshold of the abnormal period coefficient difference, then the first monitoring period T / 4 is generated.

[0032] If the second threshold of the coefficient difference during the abnormal period is less than the coefficient difference during the abnormal period, then the first monitoring period T / 6 is generated.

[0033] An air conditioning baffle is prepared by the above-mentioned injection molding process.

[0034] The beneficial effects of this invention are:

[0035] (1) By adding a high-temperature resistant antioxidant, the air conditioner baffle of the present invention can effectively improve the high-temperature resistance and oxidation resistance of the air conditioner baffle, and solve the problem that when the air conditioner baffle is used in winter, it is located at the air outlet and is directly blown by the hot air at a higher temperature, which will cause the performance to decline and affect its service life.

[0036] (2) This invention is used to obtain injection data of molten liquid in the mold. Based on the temperature and pressure values, the injection stability coefficient is calculated. Based on the injection stability coefficient, it is compared and analyzed with the threshold to obtain the injection stability signal. When the injection stability difference signal is obtained, the monitoring period T is set to obtain the total value of injection abnormal stability time and the fluctuation value of injection abnormal stability time, and the abnormal time period coefficient is calculated. Based on the abnormal time period coefficient XSy, the monitoring period of subsequent injection is adjusted. This invention obtains the injection stability signal by real-time monitoring of mold injection, and then judges it based on time to adjust the frequency of subsequent monitoring time. This allows the monitoring frequency to be adjusted in real time according to the stability of injection, so that technicians can perform frequency conversion monitoring of injection molded products according to the monitoring frequency. This can effectively monitor the quality of air conditioner baffles produced by injection and ensure the quality of air conditioner baffle injection. Attached Figure Description

[0064] Example 4

[0065] An injection molding process for an air conditioner baffle includes the following steps:

[0066] Weigh out PP granules, add additives, mix evenly, and obtain powder;

[0067] The raw materials for the air conditioner baffle are uniformly mixed and heated to obtain a molten liquid;

[0068] The molten liquid is injected into the mold at a pressure of 90 bar-120 bar and held at 60 bar-90 bar for 10-18 seconds to obtain the thermoplastic air conditioner baffle; the thermoplastic air conditioner baffle is cooled to 20℃-40℃ to obtain the air conditioner baffle.

[0069] During the injection and holding of the molten liquid into the mold, the injection process is monitored in real time. The specific monitoring process is as follows:

[0070] Step 1: Used to obtain injection data of the molten liquid in the mold;

[0071] The injection molding data includes temperature and pressure performance values.

[0072] In some embodiments, the injection temperature of the mold and the ambient temperature are obtained, as well as the corresponding preset injection temperature and preset ambient temperature.

[0080] It should be noted that the specific values ​​of temperature and pressure are real-time values ​​obtained by temperature and pressure sensors during the monitoring period.

[0081] Step 2: Calculate the injection molding stability coefficient based on the temperature and pressure performance values;

[0082] In some embodiments, temperature and pressure values ​​are obtained and labeled as ZTb and ZPb, respectively. The obtained temperature value ZTb and pressure value ZPb are then substituted into the formula. In the figure, the injection molding stability coefficient XZw is obtained, where a1 and a2 are both proportionality coefficients, with a1 taking a value of 0.64 and a2 taking a value of 0.93;

[0083] Step 3: Based on the injection molding stability coefficient, compare and analyze it with the threshold to obtain the injection molding stability signal;

[0084] Among them, the injection molding stability signal includes the injection molding stability superior signal and the injection molding stability poor signal;

[0085] In some embodiments, the obtained injection molding stability coefficient XZw is compared with the injection molding stability coefficient threshold XZwy;

[0086] If the injection molding stability coefficient XZw is less than the injection molding stability coefficient threshold XZwy1, then an injection molding stability superior signal is generated.

[0087] If the injection stability coefficient XZw is greater than or equal to the injection stability coefficient threshold XZwy1, then an injection stability difference signal is generated.

[0088] Step 4: When the injection molding stability difference signal is obtained, set the monitoring period T, obtain the total value of injection molding abnormal stability time and the fluctuation value of injection molding abnormal stability time, and calculate the abnormal period coefficient;

[0089] In some embodiments, when an injection molding stability difference signal is obtained, a monitoring period T is set, the duration of each occurrence of the injection molding stability difference signal within the monitoring period T is obtained, and the durations of each occurrence of the injection molding stability difference signal are summed to obtain the total value of the injection molding abnormal stability time ZCY.

[0090] At the same time, the time interval between adjacent occurrences of injection molding stability difference signals is obtained, and the time intervals between adjacent occurrences of injection molding stability difference signals are summed to obtain the injection molding abnormal stability time fluctuation value ZBY.

[0091] Substitute the obtained total value of injection molding abnormal stabilization time ZCY and the fluctuation value of injection molding abnormal stabilization time ZBY into the formula. In the calculation, the abnormal period coefficient XSy is obtained; where b1 and b2 are both proportional coefficients, with b1 taking a value of 1.63 and b2 taking a value of 1.87.

[0092] Step 5: Adjust the monitoring cycle for subsequent injection molding based on the abnormal period coefficient XSy;

[0093] In some embodiments, the abnormal time period coefficient XSy and the preset value of the abnormal time period coefficient are obtained, and the difference between the abnormal time period coefficient XSy and the preset value of the abnormal time period is calculated to obtain the abnormal time period coefficient difference.

[0094] The coefficient difference during abnormal periods is compared with the first threshold and the second threshold of the coefficient difference during abnormal periods, respectively.

[0095] If the difference in coefficients during abnormal periods is less than the first threshold for the difference in coefficients during abnormal periods, then the first monitoring period T / 2 is generated.

[0096] If the first threshold of the abnormal period coefficient difference is less than or equal to the second threshold of the abnormal period coefficient difference, then the first monitoring period T / 4 is generated.

[0097] If the second threshold of the abnormal period coefficient difference is less than the abnormal period coefficient difference, then the first monitoring period T / 6 is generated;

[0098] The technical solution of this invention is as follows: It acquires injection data of molten liquid within a mold, calculates an injection stability coefficient based on temperature and pressure values, compares this coefficient with a threshold value to obtain an injection stability signal, sets a monitoring period T when an injection stability difference signal is obtained, acquires the total value of abnormal injection stability time and the fluctuation value of abnormal injection stability time, and calculates an abnormal time period coefficient. Based on the abnormal time period coefficient XSy, the monitoring period for subsequent injections is adjusted. This invention obtains a signal indicating whether injection is stable through real-time monitoring of mold injection, and then uses time as a benchmark to adjust the frequency of subsequent monitoring times. This allows for real-time adjustment of the monitoring frequency based on the stability of injection, enabling technicians to perform variable-frequency monitoring of injection-molded products. This effectively monitors the quality of injection-molded air conditioning baffles and ensures the quality of air conditioning baffle injection.
