The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0021] like Figures 1 to 7 The floating support type temperature measuring chuck shown comprises a support arm 1, two upper mounting blocks 2 and two lower mounting blocks 3, wherein the two upper mounting blocks 2 are arranged on the upper surfaces of the edges of both sides of the support arm 1, and the grooves on the opposite surfaces of the two upper mounting blocks 2 form a first mounting groove for mounting a temperature measuring plate 4; the two lower mounting blocks 3 are arranged on the lower surfaces of the edges of both sides of the support arm 1, and the grooves on the opposite surfaces of the two lower mounting blocks 3 form a second mounting groove for mounting the temperature measuring plate 4; and a plurality of temperature sensors 5 corresponding to a plurality of temperature measuring points on the molding surface of the mold are arranged on the two temperature measuring plates 4 on the opposite surfaces of the support arm 1; Among them, multiple spring plungers 6 are arranged on the supporting surface inside the first installation groove and the second installation groove close to the support arm 1 and parallel to the temperature measuring plate 4. The multiple spring plungers 6 are evenly distributed along the insertion direction to provide elastic support for the two side edges of the temperature measuring plate 4.

[0022] In the present invention, the two upper mounting blocks 2 and the two lower mounting blocks 3 are detachably arranged on the support arm 1. According to the temperature measuring plates 4 of different sizes and specifications, the positions of the upper mounting blocks 2 and the lower mounting blocks 3 can be adjusted or the mounting blocks of corresponding sizes can be replaced, so as to adapt to the installation requirements of various temperature measuring plates 4, without the need to disassemble or replace the entire support arm 1, thereby improving the versatility and flexibility of the installation structure; in addition, a spring plunger 6 is arranged in the installation groove, which can provide elastic support for the two side edges of the temperature measuring plate 4. When the temperature measuring plate 4 is subjected to external force, the spring plunger 6 can undergo elastic deformation to absorb and buffer the external force, which not only ensures that the thermocouple probe can effectively contact the molding surface of the mold to ensure the accuracy of temperature measurement, but also prevents damage to the mold or temperature measuring probe caused by external force, thereby extending the service life of the temperature measuring plate 4 and the mold.

[0023] In a preferred embodiment of the present invention, a plurality of temperature sensors 5 located on the temperature measuring board 4 are connected to the controller via a quick-plug connector. The quick-plug connector can be quickly plugged in and out. When the temperature sensor 5 needs to be replaced, it is only necessary to pull out the quick-plug connector without a complicated disassembly process, thereby improving the replacement efficiency of the temperature measuring board 4.

[0024] In the preferred embodiment of the present invention, the upper mounting block 2 and the lower mounting block 3 are provided with a plurality of mounting holes 21 along the length direction, and the plurality of mounting holes 21 penetrate the upper mounting block 2 and the lower mounting block 3 and are arranged alternately with a plurality of spring plungers 6. The spring plungers 6 can be directly installed on the support surface in the mounting groove through the self-provided mounting structure (such as threads, etc.), while the upper mounting block 2 and the lower mounting block 3 are fixed to the support arm 1 by fasteners through the penetrating mounting holes 21. The installation processes of the two are independent of each other and do not interfere with each other, which greatly improves the installation efficiency and accuracy, and avoids installation difficulties or errors caused by the mutual influence of components during the installation process.

[0025] In a preferred embodiment of the present invention, a plurality of spring plungers 6 are provided on the two supporting surfaces of the first mounting groove and the second mounting groove parallel to the temperature measuring plate 4. The bidirectional floating structure can automatically adjust the position of the temperature measuring plate 4 after installation, so that it always maintains good contact with the temperature measuring point on the mold forming surface, ensuring that the temperature sensor 5 can accurately measure the temperature of each part of the mold, thereby improving the accuracy and reliability of temperature measurement. In addition, a larger floating distance can provide a larger adjustment space for the temperature measuring plate 4. When the temperature measuring plate 4 is subjected to a large impact or vibration, the spring plunger 6 can more fully exert its elastic buffering effect, making it easier to accurately correspond to the temperature measuring point on the mold forming surface. Even in the case of large installation errors or slight unevenness on the mold surface, the temperature measuring plate 4 can ensure effective contact between the temperature sensor 5 and the temperature measuring point through floating adjustment, thereby improving the installation accuracy and temperature measurement accuracy.

[0026] Based on the above embodiment, the spring plungers 6 on the two support surfaces are staggered along the insertion direction. The staggered spring plungers 6 can ensure that the force on the temperature measuring plate 4 in all directions is more balanced in the vertical section, thereby improving the contact accuracy between the temperature sensor 5 and the temperature measuring point, and ensuring the accuracy and reliability of temperature measurement.

[0027] In another preferred embodiment, the spring plungers 6 on the two support surfaces are arranged one by one in the insertion direction, so that the mounting holes 21 of the upper mounting block 2 and the lower mounting hole 21 can use the same reference during processing, reducing the processing error caused by inconsistent references, thereby improving the processing accuracy of the mounting holes 21, ensuring that the spring plungers 6 can be accurately installed in the predetermined position, and improving the accuracy and reliability of the entire mounting structure; and the mounting holes 21 are formed by one-time processing, which can reduce the processing procedures and the number of clamping times, and avoid the positioning error and the accumulation of processing errors caused by multiple clamping.

[0028] When the spring plunger 6 in the present invention supports the temperature measuring plate 4, the support line formed by multiple spring plungers 6 is close to the edge of the temperature measuring plate 4. When the mold forming surface contacts the temperature sensor 5 on the temperature measuring plate 4, the middle of the temperature measuring plate 4 will be pressed down to form a slight concave phenomenon, which may easily cause the temperature sensor 5 on the central axis to be unable to contact the mold forming surface. Therefore, in order to effectively prevent the concave phenomenon from occurring in the middle of the temperature measuring plate 4, the two support surfaces of the two upper mounting blocks 2 and the two lower mounting blocks 3 close to the support arm 1 extend toward the central axis direction line to form an auxiliary support edge 22, and multiple spring plungers 6 are arranged on the auxiliary support edge 22.

[0029] In a preferred embodiment of the present invention, the temperature sensor 5 is a screw-type thermocouple, which is directly fixed on the object to be measured by a thread, is convenient for adjusting the temperature measurement distance, does not require a complicated installation process, and saves installation time.

[0030] In the present invention, a limit rod 7 is provided at the end of the support arm 1, and the limit rod 7 abuts against the temperature measuring plate 4. When the temperature measuring plate is inserted into the installation slot, the limit rod 7 will contact the rear end of the temperature measuring plate to control the insertion depth of the temperature measuring plate 4, so that the temperature sensor 5 can be accurately aligned with the temperature measuring point, avoiding measurement deviation caused by too deep or too shallow insertion, improving the accuracy of temperature measurement, and ensuring the reliability of temperature measurement data.

[0031] like Figure 8-11 As shown, the present invention also provides a multi-point temperature measuring device, which adopts a floating temperature measuring plate 4 installation structure, and the multi-point temperature measuring device includes: The temperature measuring trolley 100 has a universal wheel set at the bottom; The lifting module 200 is vertically arranged on the temperature measuring vehicle 100; The connecting member 300 is arranged on the lifting module 200, and includes a first connecting seat 301 connected to the support arm 1 and a second connecting seat 302 fixed on the lifting module 200, and the first connecting seat 301 and the second connecting seat 302 are hingedly arranged, and a positioning bolt 303 is arranged on the second connecting seat 302; The magnetic attraction member 400 is disposed on a side of the temperature measuring trolley 100 located on the support arm 1 and is used for preliminary positioning of the temperature measuring trolley 100; The positioning assembly includes two side guards 500 arranged on the device to be tested, a positioning plate 700 located in the middle of the two side guards 500, and a positioning pin 600 arranged on the temperature measuring trolley 100. The positioning plate 700 is provided with a positioning hole that cooperates with the positioning pin 600 for precisely positioning the temperature measuring trolley 100.

[0032] The implementation process of the present invention is to manually move the temperature measuring trolley 100 to the mold detection position, at which time the mold is in an open state, and the support arm 1 is located between the upper mold and the lower mold of the mold. By scanning the barcode corresponding to the temperature measuring position, the corresponding measurement parameters are retrieved, and the temperature measuring trolley 100 is continued to be pushed toward the mold direction. The temperature measuring trolley 100 is quickly guided to an area close to the set position by the side guard 500 to achieve preliminary positioning, and the positioning pin 600 is used in conjunction with the positioning hole to achieve precise positioning of the temperature measuring trolley 100, and the magnetic suction part 400 adsorbs the temperature measuring trolley 100 on the equipment where the mold is located. After pressing the start button, the lifting module 200 starts to rise, and the temperature measuring plate 4 located above the support arm 1 measures the temperatures of multiple temperature measuring points of the upper mold, and the measurement data is transmitted to the control The lifting module 200 then descends, and the temperature measuring plate 4 under the support arm 1 measures the temperature of multiple temperature measuring points of the lower mold. The measurement data is also transmitted to the controller. After the measurement is completed, the support arm 1 returns to the initial height position, and pushes the temperature measuring trolley 100 away from the mold detection position to separate the support arm 1 from the mold; the controller stores and processes the acquired measurement data and displays it in the form of a chart or table for easy later reference. In addition, a barcode reader is provided on the temperature measuring trolley 100 to obtain the threshold temperature of each temperature measuring point of the mold to be tested by reading the barcode at the temperature measuring position. The threshold temperature of each temperature measuring point includes a maximum threshold and a minimum threshold. When the measured value is greater than the maximum threshold or less than the minimum threshold, it will be marked with a striking color and an alarm will be sounded through a buzzer. In addition, when the device is not in use, remove the positioning bolt 303. At this time, the first connecting seat 301 can be flipped downward or swung sideways relative to the second connecting seat 302 around the hinge axis, so that the support arm 1 is folded and enters a retracted state to reduce the floor space.

[0033] In the present invention, by setting up the temperature measuring trolley 100 and the lifting module 200, the support arm 1 drives the temperature measuring component to move, thereby realizing automatic measurement, and multiple temperature sensors 5 are set on the temperature measuring plate, which can fully cover multiple temperature measuring points of the mold to avoid missed measurements, and can simultaneously measure the temperature of multiple temperature measuring points of the upper mold or the lower mold, so as to more accurately grasp the temperature distribution inside the mold and provide more reliable temperature data support for injection molding.

[0034] In the present invention, when the support arm 1 drives the temperature measuring plate 4 to measure the temperature at multiple points of the mold, the temperature measuring probe of the temperature sensor 5 is in close contact with the temperature measuring surface of the mold to accurately measure the temperature. If the support arm 1 is tilted, the levelness of the temperature measuring plate 4 will be affected, which will further lead to uneven or insufficient contact between the measuring probe and the temperature measuring surface, resulting in measurement deviation, which seriously affects the consistency and accuracy of the temperature measurement data. Therefore, a level is set on the support arm 1. The level of the support arm 1 is calibrated by the level so that the temperature measuring probe of the temperature sensor 5 on the temperature measuring plate 4 is in full contact with the mold surface, thereby improving the accuracy of temperature measurement.

[0035] The present invention also provides a temperature measurement method of a multi-point temperature measurement device, comprising the following steps: Confirm that the mold to be tested is in the open state, and ensure that the support arm 1 of the trolley accurately enters the gap between the upper mold and the lower mold of the mold; The temperature measuring trolley 100 is manually pushed to a predetermined position of the mold to be tested. At this time, the support arm 1 is between the upper mold and the lower mold of the mold, and the temperature measuring trolley 100 is fixed on the mold equipment; Start the lifting module 200, and the lifting module 200 drives the support arm 1 to rise until the temperature measuring plate 4 rises to a set height. At this time, the multiple temperature sensors 5 on the temperature measuring plate 4 are in full contact with the molding surface of the upper mold, and the data measured by the multiple temperature sensors 5 are transmitted to the controller; The lifting module 200 drives the support arm 1 to descend until the temperature measuring plate 4 descends to a set height. At this time, the multiple temperature sensors 5 on the temperature measuring plate 4 are in full contact with the molding surface of the lower mold, and the data measured by the multiple temperature sensors 5 are transmitted to the controller; The controller stores and processes the acquired measurement data and displays them in the form of charts and tables. When the measurement value exceeds the threshold range, the controller will remind the operator through eye-catching color marking and buzzer alarm.

[0036] The lifting module 200 automatically drives the support arm 1 to rise and fall, and realizes the contact measurement between the temperature measuring plate 4 and the molding surface of the mold, which reduces the complexity and time consumption of manual operation and improves the temperature measurement efficiency; and the multiple temperature sensors 5 on the temperature measuring plate 4 can measure multiple temperature measurement points of the mold at the same time, and obtain a large amount of temperature data at one time, further improving the measurement efficiency. In addition, the measurement data is stored and recorded, which is convenient for subsequent analysis and management, and provides reliable data support for process optimization, quality control and equipment maintenance.
