[0021] The exemplary embodiments disclosed in the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments disclosed in the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0022] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0023] Reference Figure 2 and Figure 4 As shown, embodiment 1 of the present application proposes a monitoring device, which may include: a shell 1, having a accommodating space for heat insulation; a switch assembly 2, arranged in the accommodating space; a trigger component 3, the trigger component 3 is connected to the shell 1, the trigger component 3 is in a first relative position relative to the shell 1 and is connected to the switch assembly 2 so that the switch assembly 2 is in a first state; the trigger component 3 is in a second relative position relative to the shell 1 and is not connected to the switch assembly 2 so that the switch assembly 2 is in a second state.

[0024] Specifically, in the technical solution adopted by the present application, the switch assembly 2 is installed in a housing 1 with a accommodating space, and the housing 1 has heat insulation properties so that the monitoring device can adapt to work in a high temperature environment. A trigger component 3 connected to the housing 1 is also provided in the monitoring device. When the trigger component 3 is in a first relative position relative to the housing 1 and contacts the switch assembly 2, the switch assembly 2 is driven to enter the first state; conversely, when the trigger component 3 is in a second relative position relative to the housing 1 and is separated from the switch assembly 2, the switch assembly 2 is driven to enter the second state; thus, when the mold mechanism adopts the monitoring device in this embodiment, the trigger component 3 can be driven by the moving component to repeatedly move between the first relative position and the second relative position to achieve the purpose of monitoring the operation of the target mechanism. The present application designs a motion monitoring mechanism customized for high temperature and high humidity environments, which is used to monitor the motion state of the mold mechanism in real time to ensure safety and efficiency during the production process. When the mechanism detects abnormal mold movement, it can quickly transmit the signal to the machine control system to trigger the safety shutdown mechanism to prevent mold damage. It is especially suitable for production environments with high mold temperatures (150℃~400℃), such as the manufacturing process of nano injection molds and die-casting molds. Special alloys and ceramic-based composite materials can be used to ensure stable operation at high temperatures up to 400℃.

[0025] Further, see Figure 2 and Figure 4 As shown, in some embodiments, it also includes: a switching component 4, which is connected to the trigger component 3, and the switching component 4 is used to change the movement direction of the trigger component 3 so that the switch component 2 is in a first state or a second state; the first state is the open state of the switch component 2 for signal transmission, and the second state is the closed state of the switch component 2 for stopping signal transmission.

[0026] Specifically, in the technical solution adopted by the present application, the switching component 4 connected to the trigger component 3 can change the movement direction of the trigger component 3 through the switching component 4, thereby triggering the switch component 2 to be in the first state or the second state. In this embodiment, the first state is the open state, which can be understood as the state in which the switch component 2 is triggered, and the second state is the closed state, which can be understood as the trigger component 3 being separated from the switch component 2. When the switch component 2 is in the open state after being triggered by the trigger component 3, the switch component 2 can transmit a signal to the machine through a cable or wireless communication technology, which can be used to indicate that the ejector plate has reached the return position. In this embodiment, the trigger component 3 and the ejector plate 8 on the mold mechanism can be linked, so that when the switch component 2 transmits a signal, it indicates that the ejector plate 8 in the mold mechanism has completed the return.

[0027] Further, see Figure 2 As shown, in some embodiments, the first end of the trigger component 3 is connected to the shell 1, and the second end of the trigger component 3 is connected to the switching component 4. The switching component 4 moves along the first direction to make the trigger component 3 move along the second direction. When the trigger component 3 is in a first relative position relative to the shell 1, the first end of the trigger component 3 is connected to the switch component 2 to put the switch component 2 in a first state; when the switching component 4 moves along the second direction, the trigger component 3 moves along the first direction. When the trigger component 3 is in a second relative position relative to the shell 1, the first end of the trigger component 3 is not connected to the switch component 2 to put the switch component 2 in a second state; the first direction is opposite to the second direction.

[0028] Specifically, in the first embodiment of the technical solution adopted by the present application, the trigger component 3 can be a ceramic rod, and the ceramic rod ejector rod is made of ceramic material with excellent heat insulation effect so as to be suitable for high temperature environment. The first end of the trigger component 3 can be connected to the housing 1, and the second end is connected to the switching component 4. When the switching component 4 moves along the first direction, the switching component 4 can drive the trigger component to move along the second direction until the trigger component 3 reaches the first relative position relative to the housing 1, so that the first end triggers the switch component 2 to be in the first state; and when the switching component 4 moves along the second direction, it is separated from the trigger component, so that the trigger component moves along the first direction, so that the trigger component is separated from the first relative position and reset to the second relative position to release the trigger action of the switch component 2, so that the switch component 2 is in the second state. The first direction and the second direction are opposite directions. In this embodiment, the first direction can be the direction of the ejector plate 8 on the mold mechanism away from the rear template, and the second direction is the direction of the ejector plate 8 close to the rear template. The distance of the first relative position is greater than the distance of the second relative position. The first end is the end of the trigger component 3 for connecting the switch assembly, and the second end is the end of the trigger component 3 for connecting the switching assembly 4. The first end and the second end are the two end portions of the ceramic rod respectively. When the ejector plate on the mold mechanism moves, the switching assembly 4 can be driven to move in the first direction or the second direction, thereby driving the trigger component 3 to connect or not connect the switch assembly 2, so that the switch assembly 2 is in the first state or the second state. The first relative position is the position where the trigger component 3 is connected to the switch assembly 2 when the switch assembly 2 is in the first state, and the second relative position is the position where the trigger component 3 is not connected to the switch assembly 2, so that when the trigger component 3 is in the second relative position, the switch assembly 2 is in the second state. The first relative position and the second relative position are the corresponding positions where the trigger component 3 extends into the interior of the housing 1 when the trigger component 3 is connected or not connected to the switch assembly 2, and when the trigger component 3 triggers the switch assembly 2, the position where the trigger component 3 is separated from the switch assembly 2 is compared with the housing, because the switch assembly 2 is triggered by the trigger component 3 extending into the housing 1, the first relative position is greater than the second relative position.

[0029] Further, see Figure 4 As shown, in some embodiments, the trigger component 3 is connected to the switch component 2 through the switching component 4, and the trigger component 3 moves along the first direction to make the switching component 4 move along the second direction. When the trigger component 3 is in a first relative position relative to the shell 1, the switching component 4 is connected to the switch component 2 to put the switch component 2 in a first state; the trigger component 3 moves along the second direction to make the switching component 4 move along the first direction. When the trigger component 3 is in a second relative position relative to the shell 1, the switching component 4 is not connected to the switch component 2 to put the switch component 2 in a second state; the first direction is opposite to the second direction.

[0030] Specifically, in the second embodiment of the technical solution adopted by the present application, the trigger component 3 is connected to the switch component 2 through the switching component 4, that is, the trigger component is used to trigger the switching component 4 to move or rotate, and the switching component 4 drives the switch component 2 to switch to the first state or the second state. Specifically, when the trigger component 3 moves along the first direction, the switching component 4 is driven to move along the second direction, and when the trigger component 3 is in the first relative position relative to the housing 1, the switching component 4 is linked to touch the switch component 2, so that the switch component 2 is in the first state; on the contrary, when the trigger component 3 moves along the second direction until the second relative position, the driving action of the switching component 4 is released, so that the connection between the switching component 4 and the switch component 2 is disconnected, and the switch component 2 is in the second state. The first direction and the second direction are opposite directions. In this embodiment, the first direction can be the direction of the ejector plate 8 on the mold mechanism away from the rear template, and the second direction is the direction of the ejector plate 8 close to the rear template. The distance of the first relative position is less than the distance of the second relative position. Due to the reverse action of the switching component 4, the force generated by the trigger component 3 following the ejector plate 8 moving in the first direction can be used as a condition for triggering the switch component 2, so that the trigger component 3 moves along the first direction until the switching component 4 triggers the switch component 2, at which time the trigger component 3 is in the first relative position, and the trigger component 3 moves along the first direction until the switching component 4 is separated from the switch component 2, at which time the trigger component 3 is in the second relative position. Therefore, the first relative position relative to the trigger component 3 penetrating into the housing 1 is smaller than the second relative position.

[0031] The second embodiment differs from the first embodiment in that the switching assembly 4 can be arranged in the housing 1 to contact the switch assembly 2, and the trigger component 3 is used to move synchronously with the ejector plate 8 of the mold mechanism. The force generated by the movement of the trigger component 3 can be used as the driving force of the switching assembly 4, thereby also being able to monitor the return condition of the ejector plate 8.

[0032] Further, see Figure 2 and Figure 4 As shown, in some embodiments, the trigger component 3 is connected to the housing 1 via an elastic component 31, and the elastic component 31 is used to provide an elastic force for switching the trigger component 3 between a first relative position and a second relative position relative to the housing 1.

[0033] Specifically, in the technical solution adopted by the present application, the switch assembly 2 can be switched from the first state to the second state by the elastic component 31. The elastic component 31 can be sleeved on the trigger component 3. In the second embodiment in which the switch assembly 2 is directly triggered by the trigger component 3, a boss structure can be provided at a position close to the first end of the trigger component 3. The elastic component 31 is elastically pressed between the boss structure and the shell 1 structure. When the trigger component is in the first relative position, the elastic component 31 can be elastically compressed. When the trigger component 3 moves in the second direction due to the switching component 4, the trigger component 3 can be in the second relative position by the rebound force of the elastic component 31, so that the switch assembly 2 is in the second state. In this embodiment, the elastic component 31 can be provided inside or outside the shell 1, and it is only necessary to elastically support the elastic component 31 between the boss structure and the shell 1 structure to apply an elastic force.

[0034] In the first embodiment of triggering the switch assembly 2 by the switching assembly 4, a boss structure can be provided on the first end of the trigger assembly, and the elastic assembly 31 is elastically pressed between the boss structure and the housing 1 structure. When the trigger assembly is in the first relative position, the boss structure drives the switching assembly 4 to move in the first direction to compress the elastic assembly 31 and trigger the switch assembly 2 to be in the first state. When the trigger assembly is in the second relative position, the boss structure is separated from the switching assembly 4 and the elastic force of the elastic assembly 31 causes the switching assembly 4 to move in the second direction, thereby disconnecting the connection between the switching assembly 4 and the switch assembly 2, so that the switch assembly 2 is in the second state. In this embodiment, the elastic assembly 31 can be provided inside the housing 1.

[0035] Further, see Figure 1 and Figure 3 As shown, in some embodiments, the shell 1 includes: a first shell 11, which is made of a heat-insulating material and is used to fix and connect the switch assembly 2; a second shell 12, which has a groove structure and is connected to the first shell 11 to form a accommodating space.

[0036] Specifically, in the technical solution adopted by the present application, the housing 1 has a closed or nearly closed heat-insulating accommodation space. The housing 1 can be composed of a first housing 11 and a second housing 12, and the switch assembly 2 can be fixed on the first housing 11, and the second housing 12 has a groove structure and is snapped on the first housing 11 to form an accommodation space. In this embodiment, the first housing 11 can be fixedly connected to the rear template of the mold mechanism, so the first housing 11 can be made of heat-insulating materials, such as heat-insulating materials such as vulcanizing machine materials, and the main function of the second housing 12 is to resist the entry of dust and impurities, so it can be made of alloy materials, such as aluminum alloy materials, etc. The second housing can also be made of the same heat-insulating material as the first housing 11.

[0037] Further, see Figure 2 and Figure 4 As shown, in some embodiments, the switching assembly 4 includes: a switching rod 41, a first end of the switching rod 41 is used to link with the ejector plate 8, and a second end of the switching rod 41 is used to apply a force to trigger the switch assembly 2; a switching shaft 42, which is rotatably connected to the switching rod 41 so that the trigger component 3 can move in the opposite direction to the ejector plate 8.

[0038] Specifically, in the technical solution adopted by the present application, the switching rod 41 includes a first end and a second end, and the first end can be connected to the ejector plate 8 on the mold mechanism. It can be understood that the switching rod 41 applies a force to the first end through the displacement of the ejector plate 8 to drive the switching rod 41 to rotate, and the force transmitted to the second end can act on the switch assembly 2, so that the switch assembly 2 is in the first state or the second state. In this embodiment, the switching rod 41 is rotatably mounted in the housing 1 or on the lower mold fixing plate 9 of the mold mechanism through the switching shaft 42, so that the force in the first direction is converted into the force in the second direction through the rotating first and second ends, or the force in the second direction is converted into the force in the first direction.

[0039] Further, see Figure 1 and Figure 2 As shown, in some embodiments, it also includes: a fixing component 5, the fixing component 5 includes: a fixing member 51, the fixing member 51 is provided with a through hole, the trigger component 3 is penetrated by the through hole and connected to the second end of the switching rod 41; a push rod 52, the fixing member 51 is connected to the first end of the switching rod 41 through the push rod 52; the monitoring device also includes: a positioning member 6, which is arranged corresponding to the switching rod 41 and is used to limit the rotation angle of the switching rod 41.

[0040] Specifically, in the technical solution adopted by the present application, when the switching assembly 4 is fixedly mounted on the lower mold fixing plate 9 of the mold mechanism, the monitoring device of the present application may further include a fixing assembly 5, which includes a fixing member 51 with a through hole, and the fixing member 51 can be fixedly connected to the ejector plate 8, and the trigger component 3 is slidably arranged in the through hole and abuts against the second end of the switching rod 41. A push rod 52 is also arranged on the fixing member 51, and the push rod 52 abuts against the first end of the switching rod 41, so that the force of moving the ejector plate 8 away from the rear template can trigger the switch assembly 2 installed on the rear template. In this embodiment, the positioning member 6 can be fixedly mounted on the lower mold fixing plate 9, respectively located on the first end and the second end of the switching rod 41 away from the ejector plate 8, so as to limit the rotation angle of the switching rod 41.

[0041] Reference Figures 1 to 4As shown, the second embodiment of the present application proposes a mold mechanism, which may include: a rear template; an ejector plate 8, which is arranged below the rear template, and the ejector plate 8 moves relative to the rear template; a monitoring device, which is connected to the rear template and the ejector plate 8 and is used to monitor the movement state of the mold mechanism, and the monitoring device includes: a shell 1, which has a accommodating space for heat insulation, and the shell 1 is connected to the rear template; a switch assembly 2, which is arranged in the accommodating space; a trigger component 3, the trigger component 3 moves synchronously with the ejector plate 8, the trigger component 3 is connected to the shell 1, the trigger component 3 is in a first relative position relative to the shell 1 and is connected to the switch assembly 2 so that the switch assembly 2 is in a first state; the trigger component 3 is in a second relative position relative to the shell 1 and is not connected to the switch assembly 2 so that the switch assembly 2 is in a second state.

[0042] Specifically, in the technical solution adopted by the present application, a mold mechanism is protected, specifically, the switch assembly 2 is installed on the rear template, so that the installation position of the switch assembly 2 is wider, and it is convenient to add a shell 1 with heat insulation and sealing properties, so that the monitoring device is suitable for high temperature environment, and the structure of the monitoring device can refer to the second embodiment mentioned above, so it will not be described repeatedly. The trigger component 3 can be fixedly installed on the ejector plate 8 through the fixing member 51, so that the trigger component 3 and the ejector plate 8 move synchronously, and when the trigger component 3 is in the first relative position, the switching rod 41 is driven to rotate, specifically, the first end is driven by the trigger component 3 to move in the first direction, and the second end moves in the second direction to contact the switch assembly 2, so that the switch assembly 2 is in the first state; conversely, when the trigger component 3 is in the second relative position, the switching rod 41 is driven to rotate, specifically, the first end is driven by the trigger component 3 to move in the second direction, and the second end moves in the first direction to disengage from the switch assembly 2, so that the switch assembly 2 is in the second state.

[0043] Further, see Figure 1 As shown, in some embodiments, it also includes: a lower mold fixing plate 9, which is arranged below the ejector plate 8, and the ejector plate 8 moves relative to the lower mold fixing plate 9; the trigger component 3 is connected to the switching component 4, and the switching component 4 is connected to the lower mold fixing plate 9, and the switching component 4 is used to change the movement direction of the trigger component 3 to make the switch component 2 in the first state or the second state; the first state is the open state of the switch component 2 for signal transmission, and the second state is the closed state of the switch component 2 for stopping signal transmission.

[0044] Specifically, in the technical solution adopted by the present application, the switch assembly 2 is installed on the rear mold plate, and the switching assembly 4 is installed on the lower mold fixing plate 9. The structure of the monitoring device can be specifically referred to the first embodiment mentioned above, so it will not be described repeatedly. When the push rod 52 located on the fixing member 51 can exert its force on the first end of the switching assembly 4 through the drive of the ejector plate 8, the switching rod 41 can be rotated, specifically, the first end moves in the first direction, and the second end moves in the second direction, so that the second end can drive the trigger component 3 to contact the switch assembly 2, so that the switch assembly 2 is in the first state; conversely, when the push rod 52 is driven by the ejector plate 8 to separate from the first end of the switching assembly 4, the force acting on the first end can disappear, so that the trigger component 3 is located at a second relative position separated from the switch assembly 2 through gravity or the elastic component 31, so that the switch assembly 2 is in the second state.

[0045] In the embodiment of the present application, if the switch assembly 2 is connected to the machine that controls the opening and closing of the mold by a cable, the cable can be made of heat-insulating material, such as a high-temperature cable made of mica. When the monitoring device of the present application is used, if the ejector plate 8 does not return to the specified position, the switch assembly 2 does not send a signal to the machine that controls the opening and closing of the mold. If the machine does not receive the signal, an alarm is issued and the operation of the mold mechanism is stopped. At this time, the mold mechanism needs to be checked and repaired to prevent the mold from being forcibly crushed by the machine.
