Description
Technical Field
[0001] The present application relates to the field of sensing detection, and in particular to an integrated injection mold cavity sensing device. Background Art
[0002] The injection molding process occupies a vital position in modern industrial production, especially in high-precision injection molding scenarios such as medical devices, electronic component packaging and other fields. The quality and performance of its products are directly related to the development level of related industries. In the injection molding process, the injection molding machine is equipped with a fixed template. By driving the movable template to fit the fixed template, a sealed mold cavity is formed between the movable template and the fixed template. The melt is injected into the mold cavity, and the melt is shaped and cooled in the mold cavity to form an injection molded product. The real-time status of the melt pressure and temperature in the mold cavity has a decisive influence on the product quality. Therefore, accurate monitoring of these two parameters has become a key link in optimizing process parameters and improving product quality.
[0003] In the prior art, in order to monitor the pressure and temperature in the injection mold cavity, a pressure sensor and a temperature sensor are respectively set in the mold cavity. The pressure sensor and the temperature sensor transmit signals to the monitoring station for display. For temperature monitoring, a thermocouple temperature sensor is generally used. When a thermocouple is used as a temperature sensor, it needs to be fixed to the side of the mold cavity by drilling. The thermocouple relies on the probe to contact the melt to transfer heat, and transfers the heat to the temperature sensing element. The temperature sensing element then senses the temperature based on the heat transfer. There is a certain amount of heat transfer time and loss, which leads to delays and errors in temperature measurement, and cannot timely and accurately reflect the actual temperature of the melt in the mold cavity. Summary of the Invention
[0004] In order to improve the accuracy of temperature measurement, the present application provides an integrated injection mold cavity sensing device.
[0005] This application provides an integrated injection mold cavity sensing device, which adopts the following technical solutions:
[0006] An integrated injection mold cavity sensing device includes a probe rod, through which a first lead and a second lead are inserted. One end of the first lead is connected to one end of the second lead, and the connection point forms a temperature sensing element. The first lead and the second lead are used to extract the temperature signal generated by the temperature sensing element. One end of the probe rod is connected to a probe. The probe has a mounting hole extending through the end of the probe away from the probe rod. The temperature sensing element is disposed in the mounting hole so that the temperature sensing element is exposed to the outside of the probe.
[0007] One end of the probe rod away from the probe is connected to a connecting pipe, and one end of the connecting pipe away from the probe rod is connected to a mounting joint, and the mounting joint is detachably connected to the connecting joint;
[0008] The mounting joint is provided with a connecting groove, which is equidistantly distributed along the circumference of the mounting joint. An elastic member is provided in the connecting groove, which is connected to the mounting joint.

When the elastic sheet is in a free state, the elastic sheet is in an arc shape, and the end of the elastic sheet away from the mounting joint is convex and arranged on the outer wall of the mounting joint. A guide groove is provided on the end side of the connecting joint away from the braided tube, and the guide groove guides the mounting joint through the elastic sheet.
[0009] By adopting the above technical solution, the temperature sensing element is located in the mounting hole on the end side of the probe away from the probe rod and is exposed to the outside of the probe. When the melt is placed in the mold cavity, the temperature sensing element can directly contact the melt in the mold cavity. When the melt contacts the temperature sensing element, a temperature signal is generated, which is led out through the first lead and the second lead. Compared with the need to transfer heat to the temperature sensing element through the probe, the temperature sensing element exposed to the outside of the probe directly contacts the melt, thereby improving the timeliness and accuracy of temperature signal acquisition. When installing the connecting joint, align the connecting joint with the mounting joint. Since the elastic members are evenly distributed around the mounting joint, and the inner wall of the connecting joint is opened The snap-in slot only requires pushing the connecting connector toward the mounting connector, and the elastic part will slide into and engage with the snap-in slot, thereby quickly fixing the connecting connector and the mounting connector, reducing tedious operations such as traditional screw connections, and greatly improving installation efficiency. Moreover, due to the presence of the elastic part, the connection has a certain buffering property, which can effectively reduce the impact of vibration on the connection stability, ensure the reliability of signal transmission, and reduce maintenance difficulty and cost. The elastic sheet is provided to facilitate guiding the installation of the connecting connector, so that the snap-in part can be accurately inserted into the snap-in slot, thereby improving the snap-in accuracy of the snap-in part, and thereby improving the installation stability of the sensing device, thereby improving the accuracy of temperature measurement.
[0010] Optionally, the probe includes a pressure sensing head, which is integrated into one end of the probe rod close to the temperature sensing element. The probe rod is used to support the pressure sensing head and provide a channel for signal transmission.
[0011] By adopting the above technical solution, the existing temperature sensors and pressure sensors need to be installed at different positions of the mold cavity wall respectively. In this application document, the temperature sensing element and the pressure sensing head are integrated in the probe, and no additional large space is required to separately place the pressure sensors, which reduces the space occupied in the mold cavity, reduces the possibility of messy and easily interfered wiring of the split sensor, reduces data matching errors, and improves data synchronization accuracy.
[0012] Optionally, the probe rod sleeve is provided with a mounting cylinder, the mounting cylinder is rotatably connected to the probe rod, and the mounting cylinder is threadedly connected to the injection molding machine.
[0013] By adopting the above technical solution, the integrated injection mold cavity sensing device can be threadedly connected to the injection molding machine through the installation cylinder, which facilitates the installation of the device.
[0014] Optionally, the outer wall of the installation cylinder is connected to a screwing ring, and the outer wall of the screwing ring is provided with sharp corners.
[0015] By adopting the above technical solution, the sharp edges of the outer wall of the screwing ring make it easier for the operator to manually rotate the screwing ring, thereby driving the installation barrel to rotate, so that the installation barrel can be more easily threadedly connected or disassembled with the injection molding machine, thereby facilitating the installation and disassembly of the integrated injection mold cavity sensing device.
[0016] Optionally, a signal acquisition module is provided in the connecting joint, the connecting joint is connected to a braided tube, a signal transmission line is inserted into the braided tube, and the signal transmission line is electrically connected to the signal acquisition module.
[0017] By adopting the above technical solution, the signal acquisition module in the connecting joint can collect the temperature signal generated by the temperature sensing element and the pressure signal generated by the pressure sensing head, and then transmit the signal to the monitoring station via the signal transmission line to ensure stable signal transmission.
[0018] Optionally, the elastic member includes a connecting piece, a snap-fit piece and a limiting piece, the connecting piece is connected to the mounting joint, the end of the connecting piece away from the mounting joint is connected to the snap-fit piece, the connecting part of the connecting piece and the snap-fit piece forms a snap-fit portion, the end of the snap-fit piece away from the connecting piece is connected to the limiting piece, one side of the limiting piece is abutted against the mounting joint, and the snap-fit portion is engaged with the mounting joint by inserting into the snap-fit groove.
[0019] Optionally, a limit ring is connected to the outer wall of the mounting joint.
[0020] By adopting the above technical solution, the position of the connecting joint is restricted, the possibility of the connecting joint sliding or detaching at will is reduced, and the connection between the installation joint and the connecting joint is made more stable and reliable.
[0021] In summary, this application includes at least one of the following beneficial technical effects:
[0022] 1. The temperature sensing element is located in the mounting hole on the end of the probe away from the probe rod and is exposed to the outside of the probe. When the melt is placed in the mold cavity, the temperature sensing element can directly contact the melt in the mold cavity. When the melt contacts the temperature sensing element, a temperature signal is generated, which is conducted through the first lead and the second lead. Compared with the need for heat transfer through the probe to the temperature sensing element, the temperature sensing element exposed to the outside of the probe directly contacts the melt, improving the timeliness and accuracy of temperature signal acquisition;
[0023] 2. Existing temperature sensors and pressure sensors require installation of pressure and temperature sensors at different locations on the mold cavity wall. In this application, the temperature sensing element and pressure sensor head are integrated into the probe, eliminating the need for additional large space to house the pressure sensor separately. This reduces space occupied within the mold cavity, reduces the possibility of messy wiring and interference with separate sensor types, reduces data matching errors, and improves data synchronization accuracy.

It can resist the erosion of chemical substances in the melt, ensure the stability and reliability of the performance of the sensing device, reduce the possibility of damage to the pressure sensing head and temperature sensing element caused by the high temperature melt during the injection molding process, and extend its service life. At the same time, the transparent material makes it easy to observe the status of the pressure sensing head and temperature sensing element, which is conducive to timely detection of potential problems and facilitates subsequent maintenance and repair.

At the same time, the melt extrude the pressure sensing head 3, and the pressure sensing head 3 transmits the pressure signal to the signal acquisition module 61 through the third lead.

[0039] Reference Figure 4 The mounting joint 5 is provided with a connecting groove 51, which is evenly spaced along the circumference of the mounting joint 5. An elastic member 52 is provided in the connecting groove 51, and the elastic member 52 is connected to the mounting joint 5. The inner wall of the connecting joint 6 is provided with a clamping groove 63, and the connecting joint 6 is fixed to the mounting joint 5 by the elastic member 52 being engaged with the groove wall of the clamping groove 63. Specifically, the elastic member 52 includes a connecting piece 521, a clamping piece 522 and a limiting piece 523. The connecting piece 521, the clamping piece 522 and the limiting piece The positioning piece 523 is formed as a whole, and the connecting part of the connecting piece 521 and the clamping piece 522 forms a clamping portion, which is provided in a convex shape on the outer wall of the connecting joint 6. The connecting piece 521 is connected to the mounting joint 5, and the end of the connecting piece 521 away from the mounting joint 5 is connected to the clamping piece 522, and the end of the clamping piece 522 away from the connecting piece 521 is connected to the limiting piece 523. One side of the limiting piece 523 is against the mounting joint 5, and the clamping portion is engaged with the mounting joint 5 by inserting into the clamping groove 63.
[0040] The outer wall of the mounting joint 5 is fixedly connected to a limiting ring 53, which is located at one end of the mounting joint 5 close to the connecting pipe 4. The outer wall of the limiting ring 53 is provided with an annular anti-slip pattern 531. When the clamping portion is clamped into the clamping groove 63 and engaged with the elastic member 52, the end side of the limiting ring 53 away from the connecting pipe 4 is in contact with the end side of the connecting joint 6 away from the braided tube 62.
[0041] The two groove walls of the adjacent clamping parts of the clamping groove 63 are arranged at an angle, so that the area of the groove of the clamping groove 63 is larger than the area of the groove wall of the clamping groove 63 away from the groove. When the connecting joint 6 and the mounting joint 5 are unlocked, the connecting joint 6 is rotated so that the clamping part is removed from the clamping groove 63 through the inclined groove wall on one side of the clamping groove 63, so that the connecting joint 6 and the mounting joint 5 unlock the clamping structure, and then the connecting joint 6 is slid in the direction away from the limiting ring 53 until the mounting joint 5 is separated from the connecting joint 6, thereby realizing the disassembly of the connecting joint 6 and the mounting joint 5 and improving convenience.
[0042] Furthermore, when it is necessary to connect the installation joint 5 and the connecting joint 6, the connecting joint 6 is pushed, and the connecting joint 6 slides against the outer wall of the installation joint 5. At the same time, the connecting joint 6 pushes the connecting piece 521 to move toward the axis of the installation joint 5, so that the connecting piece 521 and the clamping piece 522 cannot protrude from the outer wall of the installation joint 5, which facilitates the sliding of the connecting joint 6 on the outer wall of the installation joint 5 until the end side of the connecting joint 6 away from the braided tube 62 is against the end side of the limiting ring 53 away from the connecting tube 4. At this time, the clamping part is clamped in the groove wall of the clamping groove 63 close to the end of the limiting ring 53, thereby realizing the clamping operation of the installation joint 5 and the connecting joint 6.
[0043] The outer wall of the mounting joint 5 is provided with an avoidance groove 54, and an elastic sheet 7 is provided in the avoidance groove 54. The elastic sheet 7 is located between adjacent connecting grooves 51, and one end of the elastic sheet 7 is fixedly connected to the mounting joint 5. When the elastic sheet 7 is in a free state, the elastic sheet 7 is in an arc shape. In this example, the elastic sheet 7 is in the shape of a square arc. The end of the elastic sheet 7 away from the mounting joint 5 is convex and arranged on the outer wall of the mounting joint 5. A guide groove 64 is provided on the end side of the connecting joint 6 away from the braided tube 62. The guide groove 64 guides the mounting joint 5 through the elastic sheet 7. When the elastic sheet 7 is inserted into the guide groove 64, the side of the elastic sheet 7 away from the avoidance groove 54 abuts against the groove wall of the guide groove 64, and the groove wall of the guide groove 64 away from the notch is in the shape of an inclined chamfered surface. When the end of the elastic sheet 7 away from the mounting joint 5 is attached to the avoidance groove 54, the clamping portion is clamped into the clamping groove 63. In this example, the elastic sheet 7 is made of elastic stainless steel.
[0044] When it is necessary to connect the installation joint 5 with the connecting joint 6, align the guide groove 64 with the elastic sheet 7, push the connecting joint 6, and make the elastic sheet 7 abut the inclined chamfered surface of the guide groove 64. When the connecting joint 6 does not push the elastic sheet 7, the elastic sheet 7 is in an arc shape and continues to push the connecting joint 6 so that the connecting joint 6 pushes the elastic sheet 7. When the connecting joint 6 pushes the elastic sheet 7, the elastic sheet 7 starts from the end close to the installation joint 5 and sequentially fits the groove wall of the avoidance groove 54 away from the groove, until the elastic sheet 7 gradually and completely fits the groove wall of the avoidance groove 54 away from the groove. At this time, the elastic sheet 7 is in a straight line shape, one side of the elastic sheet 7 is against the groove wall of the avoidance groove 54 away from the notch, and the side of the elastic sheet 7 away from the groove wall of the avoidance groove 54 is against the inner wall of the mounting joint 5. At the same time, the connecting joint 6 squeezes the connecting sheet 521, so that the connecting sheet 521 moves toward the axis of the mounting joint 5. The elastic sheet 7 completes the guiding effect of the connection between the connecting joint 6 and the mounting joint 5, and continues to push the connecting joint 6 until the clamping piece is inserted into the clamping groove 63, thereby completing the connection between the connecting joint 6 and the mounting joint 5, and improving the accuracy of the clamping piece.
[0045] The implementation principle of an integrated injection mold cavity sensing device in this embodiment is as follows: the integrated injection mold cavity sensing device integrates the pressure sensing head 3 and the temperature sensing element 14 at one end of the probe rod 1 through an integrated design, thereby reducing the space occupied by the mold cavity 13 and reducing the possibility of confusion in the wiring of discrete sensors. When the mold cavity 13 is filled with melt, the temperature sensing element 14 can directly contact the melt in the mold cavity 13. When the melt contacts the temperature sensing element 14, a temperature signal is generated, and the signal is derived to the signal acquisition module 61 through the first lead and the second lead. At the same time, the melt squeezes the pressure sensing head 3, and the pressure sensing head 3 derives the signal to the signal acquisition module 61 through the third lead. Subsequently, the signal acquisition module 61 transmits the signal to the monitoring station through the signal transmission line. Compared with the need to transfer heat to the temperature sensing element 14 through the probe, the temperature sensing element 14 exposed to the outside of the probe directly contacts the melt, thereby improving the timeliness and accuracy of temperature signal acquisition.
