Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0059] Combine the following Figure 1-Figure 9 The invention describes a control method of an injection mold for manufacturing automobile parts and an injection mold.

[0060] An embodiment of one aspect of the present invention, referring to Figure 1 , Figure 4 and Figure 6 As shown, a control method for an injection mold for manufacturing automobile parts is improved, comprising:

[0061] S101, start injection, and the injection mold injection-molds the first workpiece A and the second workpiece B; wherein the injection mold comprises a first mold core body 100 and a second mold core body 200, the first mold core body 100 has a molding surface 110, the second mold core body 200 and the first mold core body 100 can move relative to each other, and the molding surface 110 and the second mold core body 200 cooperate to mold the first workpiece A and the second workpiece B;

[0062] It can be understood that in this embodiment, the first workpiece A and the second workpiece B can be injection molded simultaneously on one injection mold, and the materials of the first workpiece A and the second workpiece B can be the same or different, that is, automotive accessories made of two different materials can be produced on the same injection mold, namely, molding the first workpiece A (for example: a card pin), and molding the second workpiece B (for example: a card seat), which is beneficial to reducing production costs and reducing occupied space.

[0063] S102, obtaining first temperature information of the first mold core body 100 and second temperature information of the second mold core body 200;

[0064] It is understandable that the temperature information of the first mold body 100 and the second mold body 200 can be detected by setting separate temperature sensors in the first mold body 100 and the second mold body 200. Specifically, the types of temperature sensors include but are not limited to thermocouples, thermistors, infrared sensors or thermal resistors, etc., which can be selected according to specific application requirements and environmental conditions. For example, thermocouples can be used to measure the temperature information of the first mold body 100 and the second mold body 200 because thermocouples have a wide temperature measurement range and good response speed.

[0065] In an optional embodiment, a plurality of temperature sensors may be provided, and the plurality of temperature sensors may be distributed at a plurality of locations of the first mold core body 100 and the second mold core body 200 to more accurately measure the temperature information of the first mold core body 100 and the second mold core body 200 .

[0066] S103, based on the first temperature information, adjusting the working mode of the first temperature adjustment component 300 to adjust the temperature of the first mold body 100; based on the second temperature information, adjusting the working mode of the second temperature adjustment component 400 to adjust the temperature of the second mold body 200.

[0067] In this embodiment, after obtaining the first temperature information and the second temperature information, the working mode of the first temperature control component 300 is adjusted based on the first temperature information so that the working mode of the first temperature control component 300 is adapted to the temperature of the first mold core body 100, and the working mode of the second temperature control component 400 is adjusted based on the second temperature information so that the working mode of the second temperature control component 400 is adapted to the temperature of the second mold core body 200.

[0068] It should be noted that the working mode of the temperature control component may include a heating mode, a cooling mode and a heat preservation mode, which can be specifically determined according to the difference between the actual temperature of the two mold core bodies and the set temperature.

[0069] Understandably, reference Figure 2 and Figure 3As shown, the control method of the injection mold for manufacturing automobile parts of this embodiment can realize independent cooling of the first mold body 100 and the second mold body 200 by adopting independent first temperature adjustment components 300 and second temperature adjustment components 400. The advantage of such a design is that each mold body can adjust the flow rate and temperature separately, thereby realizing more accurate temperature control, improving the stability of temperature control, and further improving product accuracy, better cooling effect, and shortening the molding cycle. At the same time, such a design can also avoid interference between different mold bodies, further improving temperature stability and accuracy stability.

[0070] According to one embodiment of the present invention, referring to Figure 5 As shown, there is a gap between the first diverter plate 500 for forming the first workpiece A and the second diverter plate 600 for forming the second workpiece B, and a blowing component 700 is arranged in the gap, and the method also includes a blowing step: obtaining third temperature information of the gap; when the third temperature information is greater than a preset temperature threshold, using the blowing component 700 to blow air into the gap.

[0071] It can be understood that in the present embodiment, the first diverter plate 500 is used to divert the first injection molding material for molding the first workpiece A, and the second diverter plate 600 is used to divert the second injection molding material for molding the second workpiece B. Since the injection molding temperatures of the first workpiece A and the second workpiece B are usually different, and there may be a large temperature difference, a gap is set between the first diverter plate 500 and the second diverter plate 600, and a blowing assembly 700 is provided in the gap for blowing cooling, so as to effectively isolate the heat transfer between the first diverter plate 500 and the second diverter plate 600. Since the melting points and melting temperatures of different materials may be different, the first gap can be set to avoid mutual influence, so as to ensure that each material reaches the expected injection molding temperature; on the other hand, by providing the blowing assembly 700 in the gap for cooling, the temperature of the gap can be effectively reduced, and heat accumulation in the gap can be avoided, so that the temperature of the first diverter plate 500 and the second diverter plate 600 remains stable, stable production conditions are maintained, and the quality stability of the product is improved. At the same time, accurately controlling the temperature of the first diverter plate 500 and the second diverter plate 600 can also help to improve production efficiency, shorten production cycle, and reduce production cost.

[0072] Specifically, the third temperature information of the gap can be obtained through the temperature sensor. When the third temperature information is greater than a preset temperature threshold, the blowing assembly 700 is used to blow air into the gap to reach a temperature for cooling the gap, so that the temperature of the gap is maintained within a reasonable temperature range, thereby avoiding heat accumulation in the gap and affecting the temperature of the injection molding material in the first diverter plate 500 and the second diverter plate 600.

[0073] Table 1- Temperature comparison of injection molding materials before and after blowing

[0074]

[0075] Table 1 is a temperature comparison of the injection molding material before and after blowing in one embodiment of the present application. It can be seen from the above table that after adding the blowing component 700 for cooling, the difference between the actual temperature value of the injection molding material and the set value is reduced, thereby improving the temperature stability of the first injection molding material and the second injection molding material.

[0076] According to an embodiment of the present invention, an adjustment step is further included: determining a first difference between the third temperature information and a preset temperature threshold, and adjusting at least one of the blowing temperature, blowing flow rate and blowing frequency of the blowing component 700 based on the first difference.

[0077] It is understandable that in this embodiment, the third temperature information is obtained through a sensor or other temperature measuring device, and compared with the preset temperature threshold, the first difference between the two is calculated, and at least one of the blowing temperature, blowing flow rate and blowing frequency is adjusted according to the size of the first difference. Specifically, when the first difference is large, the blowing temperature can be reduced, the blowing flow rate can be increased, or the blowing frequency can be increased to accelerate heat transfer, improve heat exchange efficiency, and achieve rapid cooling, so that the third temperature information reaches the preset temperature threshold faster. When the first difference is small, the blowing temperature can be appropriately increased, the blowing flow rate can be reduced, or the blowing frequency can be reduced. Under the premise of meeting production requirements, the blowing time, blowing frequency or blowing temperature can be reduced to avoid unnecessary energy consumption and save energy use.

[0078] According to one embodiment of the present invention, referring to Figure 5 As shown, there are multiple first diverter plates 500 and second diverter plates 600, and the gap between each first diverter plate 500 and second diverter plate 600 is provided with an independently controlled blowing assembly 700, and each blowing assembly 700 is suitable for independently performing a blowing step and / or an adjustment step.

[0079] It can be understood that in the present embodiment, the number of the first diverter plates 500 and the second diverter plates 600 is multiple, and the production of as many first workpieces A and second workpieces B as possible can be achieved on one injection mold; and a gap is arranged between each of the first diverter plates 500 and the second diverter plates 600, and an independently controlled blowing assembly 700 is arranged in the gap, and the blowing step and the adjustment step of the corresponding blowing assembly 700 can be controlled according to the third temperature information of each gap.

[0080] Specifically, whether blowing is needed can be determined based on the third temperature information of each gap. If the third temperature information of a gap exceeds the set preset temperature threshold, the corresponding blowing component 700 is turned on to introduce cold air into the gap for cooling. If the third temperature information is within a reasonable range, the blowing component 700 is turned off to avoid unnecessary energy consumption.

[0081] In addition, the parameters such as the blowing temperature, flow rate or frequency of the blowing assembly 700 can be adjusted according to the third temperature information of each gap to achieve more accurate temperature control. If the third temperature information is too high, the blowing temperature can be reduced or the blowing flow rate can be increased to speed up the cooling speed; if the third temperature information is too low, the blowing temperature can be appropriately increased or the blowing flow rate can be reduced to avoid excessive cooling.

[0082] By controlling the blowing step and the adjusting step according to the third temperature information of each gap, different gaps can be individually controlled according to actual conditions, thereby improving the accuracy of temperature control to ensure temperature stability and product quality compliance.

[0083] According to one embodiment of the present invention, based on the first temperature information, adjusting the working mode of the first temperature adjustment component 300 to adjust the temperature of the first mold core body 100 includes: when the first temperature information is less than or equal to the first temperature threshold, adjusting the working mode of the first temperature adjustment component 300 to the heating mode; when the first temperature information is greater than the first temperature threshold and the first temperature information is less than the second temperature threshold, adjusting the working mode of the first temperature adjustment component 300 to the heat preservation mode; wherein the second temperature threshold is greater than the first temperature threshold; when the first temperature information is greater than or equal to the second temperature threshold, adjusting the working mode of the first temperature adjustment component 300 to the cooling mode.

[0084] It is understandable that, in this embodiment, when the first temperature information is less than or equal to the first temperature threshold, the working mode of the first temperature regulating component 300 is set to the heating mode, which means that the first temperature regulating component 300 will provide heat to increase the temperature and help reach the set target temperature. When the first temperature information is greater than the first temperature threshold and less than the second temperature threshold, the working mode of the first temperature regulating component 300 is set to the insulation mode. In this mode, the first temperature regulating component 300 will maintain the temperature within a relatively stable range to avoid excessive heating or cooling. When the first temperature information is greater than or equal to the second temperature threshold, the working mode of the first temperature regulating component 300 is set to the cooling mode. In this case, the first temperature regulating component 300 will operate to reduce the temperature to ensure that the temperature does not exceed the set upper limit. By selecting a suitable working mode according to different temperature thresholds and the first temperature information, precise control of the first temperature regulating component 300 can be achieved.

[0085] According to one embodiment of the present invention, based on the second temperature information, adjusting the working mode of the second temperature adjustment component 400 to adjust the temperature of the second mold core body 200 includes: when the second temperature information is less than or equal to the third temperature threshold, adjusting the working mode of the second temperature adjustment component 400 to the heating mode; when the second temperature information is greater than the third temperature threshold and the second temperature information is less than the fourth temperature threshold, adjusting the working mode of the second temperature adjustment component 400 to the heat preservation mode; wherein the fourth temperature threshold is greater than the third temperature threshold; when the second temperature information is greater than or equal to the fourth temperature threshold, adjusting the working mode of the second temperature adjustment component 400 to the cooling mode.

[0086] It is understandable that, in this embodiment, when the second temperature information is less than or equal to the third temperature threshold, the working mode of the second temperature regulating component 400 is set to the heating mode, which means that the second temperature regulating component 400 will provide heat to increase the temperature and help reach the set target temperature. When the second temperature information is greater than the third temperature threshold and less than the fourth temperature threshold, the working mode of the second temperature regulating component 400 is set to the insulation mode. In this mode, the second temperature regulating component 400 will maintain the temperature within a relatively stable range to avoid excessive heating or cooling. When the second temperature information is greater than or equal to the fourth temperature threshold, the working mode of the second temperature regulating component 400 is set to the cooling mode. In this case, the second temperature regulating component 400 will operate to reduce the temperature to ensure that the temperature does not exceed the set upper limit. By selecting a suitable working mode according to different temperature thresholds and the second temperature information, precise control of the second temperature regulating component 400 can be achieved.

[0087] According to one embodiment of the present invention, the method further includes:

[0088] Determine a second difference between the first temperature information and the first standard temperature, and adjust the power of the first temperature adjustment component 300 based on the second difference; determine a third difference between the second temperature information and the second standard temperature, and adjust the power of the second temperature adjustment component 400 based on the third difference.

[0089] It is understandable that, in this embodiment, the first standard temperature is the set temperature for the first mold core body 100. When the second difference between the first temperature information and the first standard temperature is large, it means that the difference between the first temperature and the first standard temperature is large, and a larger adjustment is required. At this time, the power of the first temperature adjustment component 300 can be set higher to speed up the temperature adjustment. When the second difference is small, it means that the difference between the first temperature and the first standard temperature is small, and a smaller adjustment is required. At this time, the power of the first temperature adjustment component 300 can be set lower to reduce energy consumption and avoid over-adjustment.

[0090] Similarly, those skilled in the art will appreciate that the power regulation method of the second temperature regulating component 400 is similar to that of the first temperature regulating component 300 , and will not be elaborated in this application.

[0091] According to one embodiment of the present invention, referring to Figure 2 and Figure 3 As shown, the first mold core body 100 and the second mold core body 200 each include a plurality of independently arranged mold core monomers, and each mold core monomer is independently provided with a sub-temperature control component. The method further includes: adjusting the working mode of the sub-temperature control component corresponding to the mold core monomer based on the temperature information corresponding to each mold core monomer.

[0092] It can be understood that in this embodiment, the first mold body 100 and the second mold body 200 each include a plurality of independently arranged mold monomers, and the plurality of mold monomers can be manufactured and processed separately, which provides flexibility in the manufacturing process; separate independent manufacturing can select different processing techniques and materials according to actual needs to ensure that each component can meet the required accuracy, strength and surface quality requirements, and multiple components can be processed and produced at the same time, thereby shortening the entire manufacturing cycle and improving production efficiency. Figure 2 and Figure 3 Multiple independently configured pipelines in a.

[0093] Furthermore, each mold core monomer is independently provided with a sub-temperature adjustment component, and according to the temperature information of each mold core monomer, the working mode of the sub-temperature adjustment component corresponding to the mold core monomer is adjusted to achieve fine adjustment and improve the accuracy and stability of temperature control.

[0094] According to one embodiment of the present invention, the number of the first mold core body 100 and the number of the second mold core body 200 are both multiple, and the method further includes:

[0095] Determine a first average temperature value of a plurality of first mold core bodies 100 and use the first average temperature value as first temperature information; determine a second average temperature value of a plurality of second mold core bodies 200 and use the second average temperature value as second temperature information.

[0096] It can be understood that in the present embodiment, there are multiple first mold core bodies 100 and second mold core bodies 200, and multiple workpieces can be produced on the injection mold to improve production efficiency. At the same time, the average temperature of multiple first mold core bodies 100 is used as the first temperature information, and the average temperature of multiple second mold core bodies 200 is used as the second temperature information, which can better reflect the average temperature of the entire area, thereby making the temperature control more accurate and stable.

[0097] Another embodiment of the present invention provides an injection mold for manufacturing automotive accessories, including an injection mold body and a controller, the injection mold body including a first mold body 100 and a second mold body 200 that can move relative to each other to form a first workpiece A and a second workpiece B, a first temperature control component 300 for adjusting the temperature of the first mold body 100, and a second temperature control component 400 for adjusting the temperature of the second mold body 200, the controller is used to execute the control method of the injection mold for manufacturing automotive accessories of any of the above embodiments.

[0098] It is understandable that the injection mold of this embodiment can realize independent cooling of the first mold body 100 and the second mold body 200 by adopting the independent first temperature adjustment component 300 and the second temperature adjustment component 400. Each mold body can adjust the flow rate and temperature separately, so as to realize more accurate temperature control, improve the stability of temperature control, and further improve the product precision, better cooling effect, and shorten the molding cycle. At the same time, this design can also avoid interference between different mold bodies, and further improve temperature stability and precision stability.

[0099] In an alternative embodiment, reference Figure 6 and Figure 7 As shown, the first mold core body 100 has a molding surface 110, and the first mold core body 100 and the second mold core body 200 can move relatively, and the molding surface 110 and the second mold core body 200 cooperate to mold automobile parts. It is realized that two automobile parts made of different materials can be produced on the same injection mold, that is, the first workpiece A (for example, a card pin) is molded, and the second workpiece B (for example, a card seat) is molded, which is conducive to reducing production costs and reducing occupied space.

[0100] Specifically, refer to Figure 6 , Figure 7 and Figure 8As shown, the first mold core body 100 includes a first mold core monomer 120 and a second mold core monomer 130, and the first mold core monomer 120 and the second mold core monomer 130 are independently arranged side by side, and the side surfaces of the first mold core monomer 120 and the second mold core monomer 130 facing the second mold core body 200 cooperate to form a molding surface 110; the first mold core monomer 120 cooperates with a partial structure of the second mold core body 200 to form a first molding chamber 240 for molding the first workpiece A; the second mold core monomer 130 cooperates with another partial structure of the second mold core body 200 to form a second molding chamber 250 for molding the second workpiece B. The second mold body 200 includes a fixed mold part 210, a first movable mold part 220 and a second movable mold part 230. The fixed mold part 210 and the first mold unit 120 are arranged opposite to each other to form and position the opposite two sides of the periphery of the first workpiece A. The first movable mold part 220 and the second movable mold part 230 are arranged opposite to each other to form and position the other opposite two sides of the periphery of the first workpiece A and the opposite two ends of the first workpiece A along the length direction.

[0101] By arranging multiple components facing each other, the first workpiece A can be better fixed and positioned, ensuring stability and accuracy during the molding process, which is beneficial to improving the molding quality of the product; since the relative arrangement of the components can more accurately position the first workpiece A, the debugging time and the time for adjusting the molding parameters can be reduced, thereby improving production efficiency; through multi-directional positioning settings, the consistency and stability of the first workpiece A during the molding process can be ensured, avoiding product quality problems caused by inaccurate positioning.

[0102] And through the above structure, the first mold core unit 120, the second mold core unit 130, the fixed mold core part 210, the first movable mold core part 220 and the second movable mold core part 230 can be manufactured and processed separately, and the manufacturing process is flexible; separate independent manufacturing can select different processing technologies and materials according to actual needs to ensure that each component can meet the required accuracy, strength and surface quality requirements, and multiple parts can be processed and produced at the same time, thereby shortening the entire manufacturing cycle and improving production efficiency; in addition, the design of the first movable mold core part 220 and the second movable mold core part 230 can be adjusted along different directions to facilitate film closing and demolding, and they can slide along the first direction and the second direction respectively, and adjust their position relative to the fixed mold core part 210, so as to adapt to the production of workpieces of different shapes and specifications.

[0103] Specifically, in some embodiments, reference Figure 2 , Figure 3 and Fig. 9As shown, the first mold core monomer 120 and the second mold core monomer 130 are detachably provided on the first mold plate 10, and the fixed mold core part 210, the first movable mold core part 220 and the second movable mold core part 230 are detachably provided on the second mold plate 20; after the first mold core monomer 120, the second mold core monomer 130, the fixed mold core part 210, the first movable mold core part 220 and the second movable mold core part 230 are independently manufactured, it is easier to replace and maintain the parts. For example, when a first mold core monomer 120 is damaged, only the part needs to be replaced without replacing the entire mold, which reduces the maintenance cost and downtime; the independently manufactured mold parts can be separately inspected and adjusted for quality to ensure that the accuracy and quality of each part meet the requirements. At the same time, if the mold needs to be adjusted or improved, it is also more convenient to modify or replace specific parts.

[0104] Furthermore, the first mold core monomer 120, the second mold core monomer 130, the fixed mold core part 210, the first movable mold core part 220 and the second movable mold core part 230 are all provided with independent cooling water channels, and the cooling water channel of each component can adjust the flow and temperature separately, so as to achieve more accurate temperature control, improve the stability of temperature control, and further improve the product precision, better cooling effect and shorten the molding cycle. At the same time, this design can also avoid interference between different components, and further improve the temperature stability and precision stability.

[0105] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
