[0051] The utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0052] Embodiment One

[0053] The present embodiment relates to a mold changing device, which can save the time for changing the mold on the mold changing equipment; an exemplary structure thereof is shown in Figure 1 、 Figure 2 and Figure 3 .

[0054] Overall, the mold changing device comprises left-right horizontal moving mechanisms 7, and two sets of front-rear moving mechanisms 6 arranged side by side on the left-right horizontal moving mechanisms 7, and each of the two front-rear moving mechanisms 6 is provided with a mold clamping and mounting mechanism 5 for fixing the mold; the left-right horizontal moving mechanisms 7 can drive the two front-rear moving mechanisms 6 to move left and right, so that one of the two front-rear moving mechanisms 6 is opposite to the mold arrangement position on the mold changing equipment; the front-rear moving mechanisms 6 can drive the mold clamping and mounting mechanisms 5 to move forward and backward, so as to move the mold on the mold clamping and mounting mechanisms 5 to or away from the mold arrangement position.

[0055] It should be pointed out that, based on the overall design idea described above, the technical scheme of the present application can adopt various different specific implementation structures, forms or configuration sequences. For example, the front-rear moving mechanisms 6, the left-right horizontal moving mechanisms 7 and the up-down jacking mechanisms 8 described above can adopt hydraulic drive mode, or can adopt motor drive mode; the transmission mode in each transmission mechanism can also adopt screw transmission structure, or can adopt rack, belt and other transmission structures. The specific setting sequence, assembly mode, etc. of the mold clamping and mounting mechanisms 5, the front-rear moving mechanisms 6, the left-right horizontal moving mechanisms 7, the up-down jacking mechanisms 8, etc. can also be flexibly adjusted. For the parts required by the overall scheme implementation but not involved in the above overall setting, reasonable and flexible design can be made by referring to the mature setting means in the field, the actual situation during implementation, etc. The specific implementation scheme described below in the present embodiment is only one of the relatively optimal schemes formed by various combinations and changes of the above, and in actual implementation, the person skilled in the art can make flexible adjustment and improvement in combination with the actual situation. Obviously, the various specific form combinations and changes of the above can form many schemes, and the specific implementation scheme of the present embodiment is all within the protection scope of the present application.

[0056] Specifically, in the present embodiment, as shown in Figure 3 、 Figure 4 , the mold clamping and mounting mechanism 5 comprises a mold mounting and fixing bottom plate 51 for bearing the mold, and a mold locking mechanism 52 for locking the mold on the mold mounting and fixing bottom plate 51. By providing the mold mounting and fixing bottom plate 51 on the mold clamping and mounting mechanism 5, a stable basis is provided for loading the mold; by locking the mold on the mold mounting and fixing bottom plate 51 with the mold locking mechanism 52, the installation firmness of the mold is guaranteed, and the stable operation of the mold working in the mold changing equipment can be ensured.

[0057] Meanwhile, a mold hanging head support mechanism 50 can also be set in the mold clamping and mounting mechanism 5. The mold hanging head support mechanism 50 is used to lock the hanging head 90 located on the top of the mold. Adding a mold hanging head support mechanism 50 to the mold clamping and mounting mechanism 5 to lock the hanging head 90 on the top of the mold can further improve the stability of the mold position in the mold changing equipment, which has a good effect on the smooth operation of the mold and the stability of the processing quality.

[0058] There are, of course, various structural solutions to be chosen for the driving method of the mold hanging head support mechanism 50 and the mold mounting and fixing base plate 51. In this embodiment, as shown in the figure... Figure 3 and combined Figure 5 As shown, the mold locking mechanism 52 is equipped with a mold locking push cylinder 520. Driven by the mold locking push cylinder 520, the mold locking mechanism 52 completes the locking action of the mold. The mold hanging head support mechanism 50 is equipped with a front and rear telescopic cylinder 500. Driven by the front and rear telescopic cylinder 500, the mold hanging head support mechanism 50 completes the locking action of the hanging head 90. The mold locking mechanism 52 is driven by the mold locking push cylinder 520, and the mold hanging head support mechanism 50 is driven by the front and rear telescopic cylinder 500. They can share the same compressed air source, and the cylinder drive also has good power performance and control reliability. In actual implementation, a mold hanging head locking button 501 and a locking control button 521 can be set on the mold clamping and mounting mechanism 5. These buttons control the corresponding solenoid valves to achieve air path control of the front and rear telescopic cylinder 500 and the mold locking push cylinder 520, thereby completing the locking and unlocking operations of the mold hanging head support mechanism 50 and the mold locking mechanism 52.

[0059] like Figure 6 , Figure 7 As shown, the forward and backward moving mechanism 6 of this embodiment includes a mold terminal mounting platform 60 for supporting the mold clamping and mounting mechanism 5, and a first drive motor 61 for driving the mold terminal mounting platform 60 to move forward and backward. The first drive motor 61 is connected to the mold terminal mounting platform 60 via a first lead screw 620. Specifically, a first linear slide rail 600 located at the bottom of the mold terminal mounting platform 60 is provided on the left and right lateral moving mechanism 7. The mold terminal mounting platform 60 is slidably mounted on the first linear slide rail 600 via a first movable slider 621 at its bottom. The first lead screw 620 is screwed to the first movable slider 621. The first drive motor 61 drives the first lead screw 620 to rotate, which in turn drives the first movable slider 621 to move the mold terminal mounting platform 60 forward and backward.

[0060] The front and back moving mechanism 6 adopts two sets of motors to drive the corresponding two mold clamping and mounting mechanisms 5 to move forward and backward, and can control the two mold clamping and mounting mechanisms 5 to move forward and backward respectively. When one mold clamping and mounting mechanism 5 is driven to the mold arrangement position, the other mold clamping and mounting mechanism 5 is driven to the standby position, so as to facilitate the mold replacement operation. The transmission mode of the motor driving the lead screw has the advantages of flexible control and stable transmission performance.

[0061] As shown in Figure 7 and Figure 8 The left and right moving mechanism 7 of the embodiment includes a front and back moving mechanism mounting plate 70 for carrying the front and back moving mechanism 6, and a second driving motor 71 for driving the front and back moving mechanism mounting plate 70 to move left and right. The second driving motor 71 is connected in transmission with the front and back moving mechanism mounting plate 70 through a second lead screw 720. Similar to the driving mode of the mold terminal mounting platform 60, the up and down jacking mechanism 8 is provided with a second linear slide rail 700 located at the bottom of the front and back moving mechanism mounting plate 70. The front and back moving mechanism mounting plate 70 is slidably arranged on the second linear slide rail 700 through a second moving block 721 at the bottom of the front and back moving mechanism mounting plate 70. The second lead screw 720 is screwed with the second moving block 721. The second driving motor 71 drives the second lead screw 720 to rotate, so as to drive the second moving block 721 to move the front and back moving mechanism mounting plate 70 left and right. At the same time, a limit sensor 73 can be arranged on the up and down jacking mechanism 8 to detect the translation position of the front and back moving mechanism mounting plate 70, so as to ensure that the selected front and back moving mechanism 6 is aligned with the mold arrangement position on the mold replacement device.

[0062] Similar to the arrangement of the front and back moving mechanism 6, the driving mode of the motor and the lead screw is adopted in the left and right moving mechanism 7, which also has the advantages of flexible and reliable control and stable transmission performance. The difference is that the front and back moving mechanism 6 is provided with two sets, and each set of front and back moving mechanism 6 needs to be equipped with a first driving motor 61, so there are two first driving motors 61. The left and right moving mechanism 7 is provided with one set, so only one second driving motor 71 is needed.

[0063] Specifically, in the embodiment, a first driving wheel 610 is arranged on the output shaft of the first driving motor 61, a first driven wheel 611 is arranged at the end of the first lead screw 620, and a first transmission belt 612 is arranged between the first driving wheel 610 and the first driven wheel 611. A second driving wheel 710 is arranged on the output shaft of the second driving motor 71, a second driven wheel 711 is arranged at the end of the second lead screw 720, and a second transmission belt 712 is arranged between the second driving wheel 710 and the second driven wheel 711. The transmission mode of the belt wheel between the motor and the lead screw not only facilitates flexible arrangement of the position of the motor, but also can achieve the effect of speed reduction and torque increase between the motor and the lead screw by setting a reasonable wheel diameter ratio between the driving wheel and the driven wheel.

[0064] As Figure 8 and in combination Figure 9 , Figure 10 shown, the mold changing device of the embodiment further comprises an up-and-down jacking mechanism 8, the left-and-right horizontal moving mechanism 7 is arranged on the up-and-down jacking mechanism 8, and the up-and-down jacking mechanism 8 can drive the left-and-right horizontal moving mechanism 7 to move up and down to change the height position of the mold clamping and mounting mechanism 5. The up-and-down jacking mechanism 8 is provided for the mold changing device, and the left-and-right horizontal moving mechanism 7, the front-and-back moving mechanism 6 and the mold clamping and mounting mechanism 5 on the left-and-right horizontal moving mechanism 7 can be driven by the up-and-down jacking mechanism 8 to move up and down to change the height position of the mold on the mold clamping and mounting mechanism 5. In this way, the mold changing device can better adapt to the mold configuration height requirements of different mold changing equipment, thereby expanding the application range of the mold changing device and improving the convenience of using the mold changing device.

[0065] Specifically, in the embodiment, the up-and-down jacking mechanism 8 comprises a lifting base plate 80 for carrying the left-and-right horizontal moving mechanism 7 and a base 81 arranged below the lifting base plate 80, the lifting base plate 80 is arranged on the base 81 in a lifting manner through a lifting guide column 82; the base 81 is provided with a third driving motor 83 and a jacking sliding block 810 capable of moving horizontally under the driving of the third driving motor 83, and the lifting base plate 80 is fixed with a jacking matching block 800; the jacking matching block 800 and the jacking sliding block 810 are matched by sliding inclined surfaces, and the jacking sliding block 810 can be lifted with the horizontal movement of the jacking sliding block 810. Among them, the third driving motor 83 is installed on the base 81, the power output shaft of the third driving motor 83 is connected with a third lead screw 840 through a shaft coupling 830, and the third lead screw 840 is screwed with the above-mentioned jacking sliding block 810; when the third driving motor 83 drives the third lead screw 840 to rotate, the jacking sliding block 810 can be driven to move horizontally in the left-and-right direction, and the jacking matching block 800 can be driven to move up and down with the lifting base plate 80 by using the sliding matching inclined surfaces between the jacking sliding block 810 and the jacking matching block 800. In order to accurately control the lifting height of the lifting base plate 80, a height measuring scale 85 can be arranged between the base 81 and the lifting base plate 80; wherein the base 81 is fixed with a scale body 850, and the lifting base plate 80 is fixed with a measuring pointer 851; with the lifting movement of the lifting base plate 80 relative to the base 81, the measuring pointer 851 can change the scale position indicated on the scale body 850.

[0066] The up-and-down jacking mechanism 8 adopts the driving form of wedge-shaped sliding block, uses the lead screw to drive the jacking sliding block 810 to move horizontally, and uses the sliding slope between the jacking sliding block 810 and the jacking matching block 800 to convert the horizontal movement into up-and-down movement, so as to well realize the up-and-down driving control of the lifting base plate 80. Moreover, the cooperation of the lead screw and the wedge-shaped sliding block not only has reliable control performance and stable lifting action, but also has high height control precision, and can better meet the requirements of high control accuracy and precision of the mold configuration height position of the mold changing equipment.

[0067] Obviously, based on the execution unit composed of the mold clamping and mounting mechanism 5, the forward-and-backward moving mechanism 6, the left-and-right transverse moving mechanism 7 and the up-and-down jacking mechanism 8 of the mold changing device, the mold changing operation on the mold changing equipment can be realized by configuring simple control buttons, indicator lights, relays and necessary lines. Figure 11 As shown in the figure, the power supply unit 1, the control unit 4, the main control panel 3, the communication unit 2 and other units can be designed and configured for the device, cooperate with the execution unit, and realize accurate and convenient control of each mechanism in the execution unit.

[0068] The control unit 4 is composed of PLC, electromagnetic valve, relay and the like, mainly completes the control of the driving components of each mechanism in the execution unit, and communicates with the communication unit and the main control panel to realize cooperative operation. The PLC includes a PLC control part and a PLC communication part. The power supply unit 1 converts 220V AC power into 36V and 24V DC power. The 36V DC power is used as power supply for the motors of each mechanism in the execution unit. The main control panel 3, the control unit 4 and the communication unit 2 use 24V DC power. The communication unit 2 is composed of a communication module and a communication interface of the PLC and communication lines, and is used to realize communication between the PLC and each mechanism, and between the PLC and the main control panel 3. The execution unit includes the mold clamping and mounting mechanism 5, the forward-and-backward moving mechanism 6, the left-and-right transverse moving mechanism 7 and the up-and-down jacking mechanism 8.

[0069] The main control panel 3 can be used to build an operation interface and display the running state of the device. It can be used to realize one-key automatic installation of mold terminals, automatic switching of different mold terminals, overall mechanical structure reset, and emergency stop control operation of the equipment in case of emergency.

[0070] When the mold changing device is used in a terminal crimping production line, the terminal crimping machine is the mold changing device, and the two sets of mold clamping and mounting mechanisms 5 on the mold changing device are respectively used to assemble two groups of terminal crimping molds 9 of different types. Since the terminal crimping machine is usually divided into a one-zone crimping and a two-zone crimping, the overall changing mechanism is also divided into two sets of one-zone and two-zone mechanisms; at this time, on the specific design on the main control panel 3, the one-zone A and B end mold mounting buttons and the two-zone A and B end mold mounting buttons can be designed for the one-zone and two-zone terminal crimping machines; at the same time, the one-zone and two-zone mechanism reset buttons, the one-zone and two-zone alarm indicator lights, and the emergency stop button are designed. The control of each zone corresponds to one mold changing device, and the related control buttons at the A and B ends correspond to two groups of terminal crimping molds 9 on the two sets of mold clamping and mounting mechanisms 5 on the same mold changing device.

[0071] In the specific working process, when the one-zone A end mold mounting button is pressed, the one-zone mold and terminal to be machined can be installed; similarly, when the two-zone A end mold mounting button is pressed, the two-zone mold and terminal to be machined can be installed. After machining is completed, the one-zone and two-zone mechanism reset buttons are pressed to complete the exit of the machined mold and terminal and switch to the next mold and terminal to be machined; after switching is completed, the one-zone and two-zone B end mold mounting buttons are pressed to complete the installation of the new mold and terminal. When the mechanism fails to move to the position or fails, the alarm indicator light will light up in the corresponding area, and when an accident occurs, the emergency stop switch is pressed, and the mold changing device will stop immediately.

[0072] In summary, the mold changing device of the embodiment, by setting two sets of front and rear moving mechanisms 6 side by side on the left and right horizontal moving mechanism 7, and setting one mold clamping and mounting mechanism 5 on each front and rear moving mechanism 6, two different types of molds can be loaded and fixed by the two mold clamping and mounting mechanisms 5 respectively. In this way, the mold changing device is set at a suitable height position on one side of the mold changing equipment, and the mold on one of the two mold clamping and mounting mechanisms 5 is located at the mold arrangement position on the mold changing equipment for mold processing operation. When the mold type on the mold changing equipment needs to be changed, the mold clamping and mounting mechanism 5 is driven by the front and rear moving mechanism 6 to move backward and withdraw from the mold changing equipment. Then the left and right horizontal moving mechanism 7 drives the other set of front and rear moving mechanism 6 to align with the mold arrangement position. Through the driving of the front and rear moving mechanism 6, the mold on the other mold clamping and mounting mechanism 5 can be moved forward to the mold arrangement position on the mold changing equipment for mold processing operation of another process specification. The mold on the withdrawn mold clamping and mounting mechanism 5 can be removed and replaced with the mold required for subsequent processes. Through the coordinated action of the left and right horizontal moving mechanism 7 and the front and rear moving mechanism 6, and the pre-removal and replacement of the mold on the mold clamping and mounting mechanism 5, the mold changing operation efficiency on the mold changing equipment can be greatly improved, thereby achieving the purpose of saving the time for changing the mold on the mold changing equipment.

[0073] Embodiment two

[0074] The embodiment relates to a terminal crimping production line, which comprises a terminal crimping machine provided with a terminal crimping mold 9 and a mold changing device provided in the embodiment one. One of the two sets of mold clamping and mounting mechanisms 5 is used to move away from the terminal crimping mold 9 located at the mold arrangement position on the terminal crimping machine, and the other is used to move the terminal crimping mold 9 to be changed to the mold arrangement position on the terminal crimping machine.

[0075] The terminal crimping production line has the technical advantages of the mold changing device. The terminal crimping mold 9 in use is delivered to the mold arrangement position on the terminal crimping machine through the mold clamping and mounting mechanism 5, and the terminal crimping mold 9 required for subsequent processes is pre-installed on the other mold clamping and mounting mechanism 5. When the mold needs to be changed, the related mechanisms in the mold changing device are controlled to cooperate and automatically change the terminal crimping mold 9 on the terminal crimping machine, and change the terminal crimping mold 9 on the other mold clamping and mounting mechanism 5. The changed terminal crimping mold 9 can be removed from the mold clamping and mounting mechanism 5, and the terminal crimping mold 9 required for subsequent processes is pre-installed for use. The whole mold changing process is fast and convenient, and the terminal crimping machine basically does not need to stop and wait, which can effectively save the mold changing time of the terminal crimping mold 9 on the terminal crimping machine, and further improve the processing efficiency of the terminal crimping machine.

[0076] The current full-automatic terminal crimping machine production process mode, manual change type, each time to replace the mold and terminal area needs two minutes of change type time long.

[0077] By comparison, it can be found that the mold change device can automatically install the terminal and the mold to the mold configuration position of the terminal crimping machine on the terminal crimping production line by one key, and can automatically exit the mold and the terminal after production by one key, and automatically change to another new mold and terminal. The whole process only needs 0.5 minutes, and the single area change type can reduce 1.5 minutes, which is 3 / 4 of the time compared with the existing change type time. And in the change process, the terminal crimping production line does not need to stop, which will not affect the hourly output of the equipment, and can improve the efficiency of the full-automatic terminal crimping machine by more than 7.5%.

[0078] At the same time, after the terminal crimping machine is provided with the mold change device, one-key quick mold change can be realized, the change process is saved, and the labor intensity of the operator is reduced. In the execution unit, the related mechanism design such as automatic jacking and translation is adopted, so that when different terminals are processed and the height of the crimping machine needs to be adjusted, the height of the mold change device will also be adjusted, the height required by the terminal crimping machine is matched, and mechanical interference and other problems in the process of quick change are prevented.

[0079] The above is only a preferred embodiment of the present application, and the detailed configuration explanation, specific structure setting form example, or assembly connection mode expression, etc. are all for the need of full disclosure, so that the present application can be better implemented by the skilled in the art, and not to limit the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
