Referring to fig. 1, a schematic view of a mold assembly according to an embodiment of the present invention is shown, and fig. 2 to 5 are partial schematic views of the mold assembly shown in fig. 1. The mold assembly provided by the embodiment of the present invention may be selected to be used for manufacturing an integrally formed housing or a component, for example, the mold assembly is used for manufacturing a mobile phone shell, or the mold assembly is used for manufacturing an automobile component.

In this embodiment, the first mold 1 and the second mold 2 are disposed opposite to each other, the first mold 1 has a molding pattern, the second mold 2 has a molding pattern, and the material is fed between the first mold 1 and the second mold 2, so that the first mold 1 and the second mold 2 can stamp and mold the material located in the middle into the component corresponding to the molding pattern. For example, after the first mold 1 and the second mold 2 are closed, the hollow structure forms a mobile phone shell model, and the mobile phone shell material is loaded between the first mold 1 and the second mold 2, so that the mobile phone shell can be formed by stamping the material located in the middle after the first mold 1 and the second mold 2 are closed. The first mold closing process comprises the steps of approaching the first mold to the second mold, carrying out impression forming and then separating; one part can be manufactured in one mold closing process; the mold assembly further comprises a control system for controlling the first mold and the second mold, and the process of controlling the mold assembly to be closed and integrally molded into parts is similar to that of the prior art and is not repeated herein.

In this embodiment, the first mold 1 has a first edge region 11 located on the edge side of the first mold 1, the second mold 2 has a second edge region 21 located on the edge side of the second mold 2, and the second edge region 21 and the first edge region 11 are adjacently disposed after the first mold 1 and the second mold 2 are clamped, and the adjacent disposition may be located on the same plane and adjacently disposed. In other embodiments, they may be located in different planes and adjacent to each other. The parts have certain thickness, so that the first mold 1 and the second mold 2 can be in direct contact or have a distance smaller than or equal to a preset mold closing distance according to different parts during mold closing. It will be understood by those skilled in the art that the mold assemblies for different parts may have different mold-closing preset distances, for example, the preset mold-closing preset distance in the mold assembly for manufacturing the mobile phone shell may be selected to be 0.1mm, and for example, the preset mold-closing preset distance in the mold assembly for manufacturing the automobile part may be selected to be 1mm, but is not limited thereto.

In this embodiment, the first mold 1 and the second mold 2 are clamped, and the distance between the first mold 1 and the second mold 2 is smaller than or equal to the preset clamping distance corresponding to the formed component, so that the first edge region 11 of the first mold 1 is close to the second edge region 21 of the second mold 2. The mold monitoring device 12 is arranged in the first edge region 11 of the first mold 1, the magnet arrangement 22 is arranged in the second edge region 21 of the second mold 2, and the mold monitoring device 12 is arranged adjacent to the magnet arrangement 22 during the closing of the molds. The magnet structure 22 is capable of generating a magnetic field.

The mold monitoring device 12 comprises a magnetic induction switch 12a and a counting module 12b, when the distance between the first mold 1 and the second mold 2 is smaller than or equal to the preset mold closing distance, the mold monitoring device 12 is arranged close to the magnet structure 22, and the magnetic induction switch 12a can receive a magnetic field signal of the magnet structure 22. When the distance between the first mold 1 and the second mold 2 is greater than the mold closing preset distance, the mold monitoring device 12 is far away from the magnet structure 22, and the magnetic induction switch 12a cannot receive the magnetic field signal of the magnet structure 22. The magnetic induction switch 12a selected in this embodiment may be closed when receiving the magnetic field signal and opened when the magnetic field signal disappears. When the mold is closed, that is, the distance between the first mold 1 and the second mold 2 is smaller than or equal to the preset mold closing distance, the magnetic induction switch 12a can receive the magnetic field signal of the magnet structure 22 and switch to the closed state; when the mold is opened, that is, the distance between the first mold 1 and the second mold 2 is greater than the preset mold closing distance, the magnetic induction switch 12a cannot receive the magnetic field signal of the magnet structure 22, and is switched to the off state. Thus, the open/close state of the magnetic induction switch 12a can represent the mold clamping times.

Based on this, when the distance between the first mold 1 and the second mold 2 is smaller than or equal to the mold-closing preset distance, the magnetic field signal of the magnet structure 22 controls the magnetic induction switch 12a to be closed, and at this time, the counting module 12b performs a mold-closing counting. Specifically, the counting module 12b may obtain the open-close state signal of the magnetic induction switch 12a in real time, and convert the close state signal of the magnetic induction switch 12a into an electrical signal to control the count value to add 1, thereby implementing counting.

It will be appreciated that the following conditions are satisfied as long as the magnet configuration and magnetic induction switch are chosen: when the distance between the first mold and the second mold is smaller than or equal to the preset mold closing distance, the magnetic field signal of the magnet structure can control the magnetic induction switch to be closed; when the distance between the first die and the second die is larger than the preset die closing distance, the magnetic field signal of the magnet structure can control the magnetic induction switch to be switched off. The embodiment of the invention does not limit the specific form of the magnet structure and the structure of the magnetic induction switch.

For example, on the basis of the above technical solution, as shown in fig. 1 to 5, in a direction in which the first mold 1 moves toward the second mold 2 for mold clamping, the first edge region 11 and the second edge region 21 may be arranged opposite to each other, and both the first edge region 11 and the second edge region 21 may have a groove structure.

In this embodiment, the mold monitoring device 12 is disposed in the first edge region 11 of the first mold 1, the magnet structure 22 is disposed in the second edge region 21 of the second mold 2, and when the mold clamping is performed, the distance between the first edge region 11 and the second edge region 21 is also smaller than or equal to the preset mold clamping distance, the mold monitoring device 12 is adjacent to the magnet structure 22. At this time, the magnetic induction switch 12a in the mold monitoring device 12 is arranged opposite to the magnet structure 22, so that the magnetic field signal of the magnet structure 22 can be received and switched to the closed state, and the counting module 12b in the mold monitoring device 12 can acquire the closed signal of the magnetic induction switch 12a and count the closed signal; on the contrary, the magnetic induction switch 12a is turned off when the mold is opened.

The first mold 1 and the second mold 2 can generate heat during mold closing, the mold monitoring device 12 is arranged in a first edge area 11, located on the edge of the mold, of the first mold 1, the magnet structure 22 is arranged in a second edge area 21, located on the edge of the mold, of the second mold 2, the influence of the mold closing heat on electronic components such as the counting module 12b can be reduced, and the performance and the service life of the counting module 12b are guaranteed.

Illustratively, on the basis of the above technical solution, the first mold 1 may alternatively have a first surface 1a facing the second mold 2 as shown in fig. 6 and 7, the first surface 1a being provided with a first edge region (not shown); the second mold 2 has a magnet holder 2a facing the first mold 1, the magnet holder 2a being provided with a second edge region (not shown).

In the present embodiment, the mold monitoring device 12 is disposed in a first edge region of the first mold 1, and the magnet structure 22 is disposed in a second edge region of the second mold 2, and a plane of the first edge region intersects a plane of the second edge region. When the mold is closed, the magnet holder 2a of the second mold 2 is in direct contact with the first surface 1a of the first mold 1, and the first edge region is close to the second edge region, so that the mold monitoring device 12 is in close proximity to the magnet structure 22.

The magnetic induction switch 12a in the mold monitoring device 12 can receive the magnetic field signal of the magnet structure 22 and switch to a closed state, and the counting module 12b in the mold monitoring device 12 can acquire the closed signal of the magnetic induction switch 12a and count the closed signal; on the contrary, the magnetic induction switch 12a is turned off when the mold is opened. The optional magnet support 2a is positioned at the edge of the second mold 2, and the corresponding first edge area is positioned at the edge of the first mold 1, so that the influence of mold closing heat on electronic components such as the counting module 12b can be reduced, and the performance and the service life of the counting module 12b are ensured.

Illustratively, on the basis of the above technical solution, the selectable magnet structure is a permanent magnet or an inductance coil, and the magnetic induction switch is a reed switch.

The conventional reed switch has a structure in which two ferromagnetic reeds are installed in a glass tube, one end of each reed is arranged in the glass tube, the other end of each reed is positioned outside the glass tube, the two reeds are opposite to each other with a certain gap between the ports in the glass tube, and inert gas is sealed in the glass tube. The magnet structure is a permanent magnet or an inductance coil, and can generate a magnetic field with certain strength.

The reed switch is switched on and off according to the principle that when the reed switch is close to the magnet structure, the magnetic field of the magnet structure induces each reed to form an N pole and an S pole, the polarities of two reed ends oppositely arranged in the glass tube at a certain gap are opposite, the two reed ends attract each other under the magnetic attraction force, and the loop of the reed switch is conducted; on the contrary, when the reed switch is far away from the magnet structure, the magnetic field signal is released, the two reeds are separated by the elasticity of the reeds to restore the original state, and the loop of the reed switch is disconnected.

It can be understood that, on the basis of the magnetic structure controlling the magnetic induction switch to switch on and off through the magnetic induction signal, the selectable magnetic structure is other magnets, and the magnetic induction switch is other structures, and is not limited to the permanent magnet, the reed switch and the like described in the embodiment.

For example, on the basis of the above technical solution, the mold monitoring device 12 shown in fig. 8 may further include a timing module 12c, where the timing module 12c is electrically connected to the magnetic induction switch 12a, and is configured to obtain a closing time node of the magnetic induction switch 12a and calculate a closing cycle length of two adjacent closing time nodes.

In this embodiment, the mold monitoring device 12 may count the mold clamping times of the mold by using a magnetic induction technique, and calculate information such as a mold clamping period. Specifically, the timing module 12c is electrically connected to the magnetic induction switch 12a, and when the magnetic induction switch 12a is closed, the timing module 12c receives the closing information and records a time node of closing of the magnetic induction switch 12a, where the closing time node specifically refers to a time node of switching the magnetic induction switch 12a from an open state to a closed state. The timing module 12c records the closing time node of the magnetic induction switch 12a during each mold closing, and the timing module 12c can calculate the time length between two adjacent closing time nodes, which is the closing period length.

The timing module 12c can also calculate an average closing period of each mold closing according to the calculated closing period length and the mold closing times counted by the counting module 12b, and a worker can check information such as the working state and the production efficiency of the mold assembly according to the average closing period.

The optional timing module is also electrically connected with the counting module, and the timing module is further used for issuing a counting instruction to the counting module when detecting that the length of the closed period is in the closed period interval so as to enable the counting module to perform primary mold closing counting.

In an ideal state, when the corresponding parts are prepared by the die assembly, the length of the closed period is in the closed period interval, the normal manufacturing process of the die is represented, and the product is a good product. If the length of the closing period is less than the minimum value of the closing period interval, the closing time of the mold assembly is too short, obviously, the mold manufacturing process is abnormal, and the product may be a defective product. If the closing period length is higher than the maximum value of the closing period interval, the closing time of the mold assembly is too long, obviously, the mold manufacturing process is abnormal, and the product may be a defective product.

Based on this, in this embodiment, the timing module may determine whether mold closing is normal according to a detection result of whether the closing cycle length is in the closing cycle interval, and the counting module may record the number of times of normal mold closing. Specifically, when the timing module detects that the closing period length is in the closing period interval, the timing module indicates that the current mold closing time length is in the normal interval, the mold closing is normal, the timing module issues a counting instruction to the counting module, and the counting module performs one-time mold closing counting. When the timing module detects that the length of the closing period exceeds the closing period interval, the timing module indicates that the current mold closing time length exceeds the normal interval, the mold closing is abnormal, the timing module does not issue a counting instruction to the counting module, and the counting module does not count the abnormal mold closing. Therefore, abnormal conditions such as accidental shaking in the die pressing process can be filtered, the low-frequency closing period is automatically filtered, and the counting result is more accurate.

The selectable counting module comprises two counting meters, wherein one counting meter records the closing times of the magnetic induction switch, the other counting meter records the instruction times of the timing module, and through comparison of the two counting meters, a worker can determine the yield and the utilization rate of the mold according to the two statistical information, find out the production defects of the mold, improve the production flow, optimize the production process and finally increase the productivity.

The optional timing module is further configured to calculate an average closed cycle of the closed cycle lengths within the closed cycle interval according to the count value of the counting module. In this embodiment, the timing module records the length of each closed cycle, counts the total closed cycle time, and combines the count value of the counting module to obtain an accurate average closed cycle, thereby saving power consumption and improving precision.

The selectable counting module comprises two counting tables, wherein one counting table records the closing times of the magnetic induction switch, the timing module can also record the length of each closing period, and no matter whether the length of the closing period is in the interval of the closing period or not, the total closing time is divided by the closing times to obtain an average closing period, and the average closing period can reflect information such as yield and the like. The selectable counting module comprises two counting tables, the other counting table records the instruction times of the timing module, the timing module can also record the length of the closing period in the closing period interval and obtain the total closing duration, and the total closing duration is divided by the times to obtain the average closing period of the normal mold closing process, and the average closing period can reflect the information such as production efficiency.

The embodiment of the invention also provides an integral structure of the intelligent terminal of the die. Referring to fig. 8, an appearance schematic diagram of a mold intelligent terminal is shown, and the mold intelligent terminal is mainly applied to an industrial mold and used for collecting times and time of regular motion in a production process, so as to count and summarize various parameters such as equipment productivity, yield and utilization rate, find out reasons for problems according to statistical information, iterate a production flow, optimize the production process, and finally increase product productivity.

The selectable magnetic induction module 101 comprises a reed switch, a corresponding magnet is arranged on the mold assembly, the reed switch is combined with the magnet in an induction mode, a coil or a permanent magnet in the reed switch is used for induction, when a magnetic field signal exists, an N pole and an S pole in the reed switch are closed to achieve circuit connection, and when the magnetic field signal disappears, due to the fact that an elastic sheet in the reed switch has elasticity, the elastic sheet is recovered to be in a disconnected state to achieve circuit disconnection. Thus, the counting function of the mold is achieved by closing the reed switch. The reed switch is used as the magnetic induction module 101, so that the magnetic induction module is more sensitive and rapid, and has long service life and low cost.

The intelligent terminal of the mold comprises a narrow-band Internet of things module, namely an NB module 103, wherein the NB module 103 is associated with an NB onboard antenna.

The intelligent terminal of the mold comprises a low-power-consumption main control chip 104, a battery module 105 and a power supply circuit 106, and low-power-consumption battery power supply is achieved. The low-power-consumption mode of the STM32L series chip is combined with the low-power-consumption mode of the NB-Iot communication module, so that the electric energy loss is saved to the maximum extent on the premise of meeting the basic application scene of a product, and the service life of more than 6 years can be reached only by using a lithium battery. Specifically, the low power consumption is combined with a stop mode of an STM32L chip and a PSM mode of BC28, when a magnetic induction signal, a drop signal and an active report signal arrive, the STM32L chip enters a run mode, and after the timing is executed for the counted time, the stop mode is entered, and microsecond-level switching greatly saves the energy consumption of the battery. When the equipment information is reported, the STM32L chip controls the BC28 to enter a connected mode from a PSM mode so as to report the equipment information, and the mode is switched to the PSM mode after the reporting is finished. Compared with the traditional power adapter power supply scheme, the power adapter uses the battery for power supply, can solve the problem of special requirements on scenes, and also saves a large amount of equipment deployment, installation and maintenance costs.
