Description

Technical Field

[0001] This invention relates to the field of mold internal inspection technology, specifically a plunger-type inspection structure that integrates mold internal visualization and temperature measurement. Background Technology

[0002] In mold processing technologies such as injection molding and die casting, the high temperature, high pressure, and enclosed environment inside the mold cavity make real-time monitoring of melt flow behavior, temperature distribution, and filling status extremely difficult. Traditionally, process engineers have relied mainly on mold cavity pressure sensors, mold thermometers, or external infrared thermometers to indirectly infer the internal state, but these methods have the following shortcomings: First, separate monitoring leads to data asynchrony and lag. It is known that temperature sensors and visual inspection usually belong to two independent systems with different installation locations and different acquisition sequences, making it difficult to obtain the temperature and shape correspondence at the same time and location.

[0003] Secondly, most existing mold monitoring systems are fixed endoscopes or external cameras, with a single observation mode, which makes it difficult to meet different observation needs; Therefore, a plunger-type inspection structure integrating internal visualization and temperature measurement of molds is proposed. Summary of the Invention

This structure integrates the endoscope structure and thermocouple module onto an openable spherical arc cover structure, and with the structural design of the quartz glass plunger, it achieves synchronous online monitoring of temperature and vision inside the mold cavity and compatibility with multiple observation modes while being compactly embedded in the mold. This effectively solves the problems of lagging separate monitoring and single observation mode in the prior art.

An endoscope structure and a thermocouple module are arranged on the arc surface of the spherical arc cover structure. When the opening and closing linkage mechanism drives the spherical arc cover structure to close, the endoscope structure and thermocouple module collect temperature and field of view data. When the opening and closing linkage mechanism drives the spherical arc cover structure to open, the observation field component can be used to provide an observation window.

The second assembly plate has a triangular locking block fixed in the middle. The first assembly plate has two locking rods rotatably mounted on it through a pin in its middle. The lower sides of the two locking rods are provided with stepped locking grooves that are adapted to and engage with the triangular locking block. The top of both locking rods is fixed with a fixing rod. The first assembly plate also includes two side blocks fixed to the opposite sides of the two fixing rods. A spring is connected between the two side blocks. The first assembly plate also includes limiting posts respectively provided on both sides of the first assembly plate. The two limiting posts are placed on both sides of the two fixing rods and limit their movement.

[0009] Preferably, the locking pin assembly includes an extension ring fixed to the top of the viewing tube. Two mounting blocks are provided on both sides of the extension ring and the inner frame. A second ratchet self-locking assembly is provided between the two mounting blocks distributed on the same side. The second ratchet self-locking assembly has the same structure as the first ratchet self-locking assembly. Under the action of the second ratchet self-locking assembly, it is used for the step-by-step extension and locking of the viewing tube relative to the inner frame.

[0010] Preferably, the opening and closing linkage mechanism includes a U-shaped frame fixed to the bottom end of the viewing tube, with inverted U-shaped frames fixed on both sides of the U-shaped frame, and a transmission plate rotatably mounted at both ends of each inverted U-shaped frame via a first rotating shaft; and two fixed frames, which are respectively fixed to both sides of the inner wall at the bottom end of the inner frame, with a transmission rod rotatably mounted at both ends of each fixed frame via a second rotating shaft, and the two transmission rods are arranged in a V-shape and are rotatably mounted on the two transmission plates on the same side via a third rotating shaft; a telescopic rod is also provided between the fixed frames and the inverted U-shaped frames on the same side; and a crossbar is connected in the middle of the two transmission rods at the same end.

Detailed Implementation

[0018] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. The various embodiments of this invention are described in detail below with reference to the accompanying drawings. Example

[0019] Please see Figures 1 to 13 The present invention preferably provides a technical solution: a plunger-type inspection structure integrating visualization and temperature measurement inside a mold, comprising: a plunger-type inspection module, which can be embedded in a stepped hole opened on the mold and extends into its cavity; the plunger-type inspection module includes a quartz glass plunger body, which includes a stepped cylindrical structure, a flange structure, and a first ratchet self-locking component 09 assembled between the two; the flange structure can be fixed to the mold by bolts; and a sensing component is provided at the front end of the stepped cylindrical structure, which includes an opening and closing linkage mechanism, and observation field components and a ball-and-socket cover structure respectively assembled to the middle and both sides of the opening and closing linkage mechanism; an endoscope structure and a thermocouple module are provided on the arc surface of the ball-and-socket cover structure; when the opening and closing linkage mechanism drives the ball-and-socket cover structure to close, the endoscope structure and the thermocouple module collect temperature and field of view data; when the opening and closing linkage mechanism drives the ball-and-socket cover structure to open, the observation field component can be used to provide an observation window.

[0020] like Figure 12 , 13As shown, in order to overcome the drawback of the difficulty in observing the inside of existing molds, this application opens a stepped hole (for daily sealing) at the end of the main runner of the existing mold or at the product injection point or overflow groove, and designs a plunger-type viewing module that can be extended into the mold cavity through the stepped hole, thereby realizing real-time monitoring of the inside of the mold. Specific examples Figure 1 , 3 As shown in Figures 4, 5, and 6; First, the quartz glass plunger body set in this application adopts a stepped cylindrical structure with the first ratchet self-locking component 09, and is fixed to the mold bolts by the flange. This not only ensures uniform clamping and reliable self-locking, and avoids leakage of melt (such as plastic and aluminum alloy) along the axial direction of the plunger body, but also, because the quartz glass itself has good thermal shock resistance and transparency, the spherical arc cover structure forms physical isolation protection for the internal optoelectronic devices, making it suitable for high temperature and high erosion mold cavity environments. Meanwhile, the plunger-type integral embedding method is assembled in the stepped hole of the mold. The front end of the quartz glass plunger body is equipped with a sensing component, and the rear flange structure is fixed to the outer mold. Not only does the overall structure occupy little axial space, but the ball arc cover structure can also realize closed collection and open observation under the control of the opening and closing linkage mechanism. No additional external adjustment device is required, avoiding interference with moving parts inside the mold (such as ejector pins and cores), and ensuring that the original mold opening and closing and ejection actions are not affected.

[0021] Secondly, by integrating the endoscope structure and thermocouple module onto the ball-and-circuit cover structure, and achieving synchronous closure and acquisition driven by the opening and closing linkage mechanism, the same-point and simultaneous acquisition of visual images and temperature data inside the mold is realized. Figure 3 , 8 As shown. Compared to traditional separate measurement or external inference methods, this method can significantly improve the accuracy and real-time performance of in-mold state monitoring, providing direct and relevant multi-physics data support for optimizing injection molding / die casting processes; The opening and closing linkage mechanism has two working states: "closed acquisition" and "open observation". Specifically, when the ball-shaped cover structure is closed, the endoscope structure and thermocouple module are in close contact with the working area of ​​the mold cavity, realizing continuous and stable temperature and image monitoring during the process. When the ball-shaped cover structure is open, the observation field component is exposed, providing a clear observation window for manual or auxiliary equipment, which facilitates shutdown inspection, anomaly verification and direct observation. This dual-mode structure improves the flexibility of the mold to adapt to different production stages (mass production monitoring, trial molding and debugging, and fault diagnosis).

[0022] Furthermore, the first ratchet self-locking assembly 09 provides axial pre-tightening and anti-loosening during assembly, and can be unlocked by pressing during disassembly without destructive disassembly; and in the switching between the open and closed states of the ball arc cover structure, the first ratchet self-locking assembly 09 can also provide longitudinal adjustment and step-by-step locking functions to achieve flexible adjustment of the degree of state switching of the ball arc cover structure. It is not only simple to operate, but also requires no additional power and has strong controllability.

[0023] Finally, the endoscope structure and thermocouple module provided in this application can be connected to the terminal to provide real-time feedback of temperature signals and image features (such as melt front position, filling shape, gas retention, etc.) at specific locations within the mold cavity.

[0024] Furthermore, the flange structure includes a housing 01, a flange body 02 fixed to the middle of the housing 01, and a flange hole 021 annularly opened on the flange body 02, wherein the flange hole 021 and the screw hole provided in the stepped hole are fixedly assembled by bolts with sealing rings.

[0025] It is worth adding that: Figure 1 , 3 As shown in 4, 5, 6, and 12, this application adds a copper or nickel gasket (soft state) between the flange body 02 and the stepped hole where the mold is located. The copper or nickel gasket is 0.3 mm thick, has an outer diameter of 17.5 mm, and an inner diameter of 14.2 mm. When the mold is locked, it generates a small amount of plastic deformation to compensate for the difference in thermal expansion and prevent high-pressure (>100 MPa) melt from penetrating. Example

[0026] In another embodiment of the present invention, the stepped cylindrical structure includes a cover 03, wherein two sets of first ratchet self-locking components 09 are provided and assembled on both sides of the cover 03 and the outer shell 01; and an inner frame 04 is provided inside the cover 03, a viewing tube 05 is provided in a through hole in the middle of the inner frame 04, and a locking pin assembly 08 is provided between one end of the viewing tube 05 and the inner frame 04, and the other end of the viewing tube 05 extends into the inner frame 04 and is assembled with the opening and closing linkage mechanism; it also includes a high-temperature resistant flexible cover 10 provided at the bottom of the inner frame 04, and the high-temperature resistant flexible cover 10 is externally provided to the opening and closing linkage mechanism and connected to both sides of the ball arc cover structure. When the opening and closing linkage mechanism drives the ball arc cover structure to close or open, the high-temperature resistant flexible cover 10 expands or retracts adaptively.

[0027] like Figure 5 As shown, the viewing tube 05 provided in this embodiment can extend and retract longitudinally relative to the inner frame 04 and be locked step by step through the locking pin assembly 08. Its bottom is also assembled with the opening and closing linkage mechanism. Therefore, by adjusting the extension and retraction degree of the viewing tube 05, the opening and closing linkage mechanism can be driven, thereby realizing the switching between the open and closed state of the ball arc cover structure. The state degree can be flexibly adjusted to facilitate finding a suitable monitoring point. It is worth noting that a perfluoroelastomer (FFKM) O-ring is installed at the connection between the viewing tube 05 and the inner frame 04. This ensures a seal while also being able to withstand temperatures above 200°C and injection molding pressures (such as 100MPa) of the telescopic rod.

[0028] Furthermore, each first ratchet self-locking assembly 09 includes a first assembly plate 091 and a second assembly plate 092 respectively fixed to the side walls of the outer shell 01 and the cover 03. The second assembly plate 092 has a triangular locking block 093 fixed in the middle. The first assembly plate 091 has two locking rods 095 rotatably mounted on it through a pin 094 in the middle. The lower sides of the two locking rods 095 are provided with stepped locking grooves 096 that are adapted to and engage with the triangular locking block 093. The top of both rods is fixed with a fixing rod 097. The first assembly plate 091 also includes two side blocks 098 fixed on the opposite sides of the two fixing rods 097. A spring 099 is connected between the two side blocks 098. The assembly plate 091 also includes limiting posts 0910 respectively provided on both sides of the first assembly plate 091. The two limiting posts 0910 are placed on both sides of the two fixing rods 097 and limit their movement.

[0029] Furthermore, the locking pin assembly 08 includes an extension ring 06 fixed to the top of the viewing tube 05. The extension ring 06 and the inner frame 04 are provided with two mounting blocks 07 on both sides. A second ratchet self-locking assembly is provided between the two mounting blocks 07 distributed on the same side. The second ratchet self-locking assembly has the same structure as the first ratchet self-locking assembly 09. Under the action of the second ratchet self-locking assembly, it is used for the step-by-step extension and locking of the viewing tube 05 relative to the inner frame 04.

[0030] It is known that the second ratchet self-locking assembly, where the locking pin assembly 08 is located, has the same structure as the first ratchet self-locking assembly 09, such as... Figure 1 , 2 As shown in Figures 3 and 4, only the first ratchet self-locking assembly 09 will be explained in detail here. like Figure 2 As shown, two stepped locking grooves 096 on opposite sides of the two locking rods 095 can be fitted and engaged with the triangular locking block 093. The two stepped locking grooves 096 are rotatably mounted on the first mounting plate 091 on the side wall of the cover 03 via a pin 094. The triangular locking block 093 is fixed to the second mounting plate 092 on the side wall of the outer shell 01. Simultaneously, fixing rods 097 are respectively provided at the top of the two locking rods 095, and a spring 099 connects the two fixing rods 097. The opposing sides of the two are limited by a limiting post 0910. Therefore, when the two locking rods 095 are brought closer to the triangular locking block 093, i.e., when the extension of the entire stepped cylindrical structure is increased, the triangular locking block 093... Figure 2 The adaptive locking mechanism engages with the appropriate positions of the two stepped locking slots 096 and locks in place in real time. Conversely, when it is necessary to unlock the two locking rods 095 and the triangular locking block 093, simply press the two locking rods 095 and compress the spring 099, thereby achieving free adjustment of the insertion depth of the stepped cylindrical structure. Example

[0031] In another embodiment of the present invention, the opening and closing linkage mechanism includes a U-shaped frame 12 fixed to the bottom end of the viewing tube 05, with inverted U-shaped frames 19 fixed on both sides of the U-shaped frame 12, and a transmission plate 18 rotatably mounted at both ends of each inverted U-shaped frame 19 via a first rotating shaft; and two fixed frames 16, which are respectively fixed to both sides of the inner wall at the bottom end of the inner frame 04, with a transmission rod 17 rotatably mounted at both ends of each fixed frame 16 via a second rotating shaft, and the two transmission rods 17 are arranged in a V-shape and are rotatably mounted on the two transmission plates 18 distributed on the same side via a third rotating shaft; a telescopic rod 20 is also provided between the fixed frames 16 and the inverted U-shaped frames 19 distributed on the same side; and a crossbar is also connected in the middle of the two transmission rods 17 distributed at the same end.

[0032] Furthermore, the spherical arc cover structure includes two symmetrically distributed transmission covers 11, each transmission cover 11 being fixed at its bottom to two transmission plates 18 distributed at the same end.

[0033] like Figure 5 , 7 As shown in Figures 8, 9, 10, and 11, two fixed frames 16 and two inverted U-shaped frames 19 are fixed to the inner frame 04 and the two sides of the U-shaped frame 12, respectively. Two transmission rods 17 and two transmission plates 18 are rotatably mounted on the fixed frames 16 and inverted U-shaped frames 19 distributed on the same side, and the two transmission rods 17 and two transmission plates 18 are rotatably mounted relative to each other, as shown in Figures 8, 9, 10, and 11. Figure 9 As shown, the two transmission covers 11, which are located in a figure-eight pattern, are set on two sets of transmission plates 18. Therefore, when the viewing tube 05 drives the U-shaped frame 12 and the inverted U-shaped frame 19 to move longitudinally, the two transmission covers 11 can be switched between open and closed states. The telescopic rod 20 and the crossbar here further improve the stability of the movement of each structure in the opening and closing linkage mechanism.

[0034] Furthermore, the observation field assembly includes a convex mirror 13 disposed at the bottom of the U-shaped frame 12; a rectangular groove opened in the middle of the bottom end of the viewing tube 05, with a transparent plate 14 disposed in the rectangular groove facing the convex mirror 13; and a ring-shaped illumination lamp 15 disposed on the outer periphery of the bottom end of the viewing tube 05.

[0035] Here, convex lens 13 is a high-temperature resistant magnifying glass; The transparent plate 14 is positioned at the bottom of the viewing tube 05 and directly above the convex mirror 13, as shown below. Figure 5 , 11As shown, this design not only does not obstruct the observation of the convex lens 13, but also prevents the internal environment of the mold from causing harm to the human body, thus improving the safety of observation. In addition, the ring light 15 further enhances the brightness of the field of vision, such as Figure 7 , 8 As shown, this improves the clarity of observation.

[0036] Furthermore, there are two endoscope structures mounted on opposite sides of two transmission covers 11. Each endoscope structure includes an endoscope body 21 mounted with the transmission cover 11 and a first built-in guide wire disposed inside the endoscope body 21.

[0037] The endoscope body 21 here is an industrial ultra-miniature endoscope, such as... Figure 5 , 11 As shown, its parameters are 4mm in diameter, 15mm in length, and it integrates 4 ring LEDs (wavelength white light), with a resolution of 640×480. Its shape is a plano-convex lens (convex facing forward), and it utilizes the principle of convex refraction to expand the field of view of the endoscope lens, allowing it to see a larger area with a limited aperture depth.

[0038] Furthermore, there are two sets of thermocouple modules, which are assembled on opposite sides of the two transmission covers 11. Each set of thermocouple modules includes several thermocouple bodies 23 disposed at the bottom of the transmission cover 11, and a second built-in wire that is built into the transmission cover 11 and electrically connected to the several thermocouple bodies 23. The second built-in wire and the first built-in wire converge to form a conductive line 22. The conductive line 22 extends to the top of the inner frame 04 and can be connected to an external wire.

[0039] Several thermocouple bodies 23 are assembled inside blind holes provided at the bottom of the transmission cover 11. Each thermocouple body 23 is preferably an armored K-type thermocouple with a diameter of 1.0 mm and filled with thermally conductive silicone grease (thermal conductivity > 3 W / m·K). The second built-in conductor is a K-type compensating conductor with glass fiber insulation and a 2-core conductor. The first built-in conductor is a 4-core conductor. Each core is a silver-plated copper stranded wire (0.12mm²). The insulation layer is polyimide + PTFE, and the outer sheath is stainless steel braided + silicone rubber. It is resistant to continuous temperatures up to 250°C. The second built-in conductor and the first built-in conductor converge to form conductor 22, which is a 6-core high-temperature shielded cable.

[0040] In this invention, unless otherwise explicitly specified and limited, the terms “installation,” “connection,” “linking,” “fixing,” etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part. There are various ways to install detachably, such as by using a plug-in and snap-fit ​​method, or by using a bolt connection, etc.

[0041] The above embodiments, which describe the specific features of the present invention, are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-essential improvements and adjustments made to the present invention by those skilled in the art based on the above description of the invention shall fall within the scope of protection of the present invention.
