Abstract
Description
Technical Field
[0001] This invention relates to the field of mold temperature controller technology, and in particular to a mold temperature controller operation control system and a mold temperature controller. Background Technology
[0002] Mold temperature controllers are used to heat, cool, and regulate the temperature control circuit of injection molding machine molds or other plastic processing equipment. An internal water pump drives the heat transfer medium from the mold inlet of the temperature controller into the mold water circuit, and then back to the temperature controller from the mold return inlet, forming a closed loop. When changing molds, the water pump needs to be reversed to draw the heat transfer medium from the mold water circuit back to the temperature controller.
[0003] In existing technologies, mold temperature controllers typically control the forward and reverse rotation of a water pump using two forward and reverse contactors. The two contactors are connected to the three-phase common bus according to the normal phase sequence and the reverse phase sequence, respectively. During the process of controlling the forward and reverse rotation of the water pump, the two contactors need to be mechanically or electrically interlocked to prevent them from engaging simultaneously. This increases the configuration of interlocking mechanisms, control outputs, and corresponding wiring, resulting in a larger number of components, a more complex structure, increased installation space, and increased manufacturing costs. Summary of the Invention

The phase sequence conversion module is used to select one of the following outputs: a forward phase sequence, a reverse phase sequence, and a stop phase sequence, so that the forward phase sequence drives the water pump motor to be controlled to rotate forward, the reverse phase sequence drives the water pump motor to be controlled to rotate in reverse, and the stop phase sequence drives the water pump motor to be controlled to stop running. Specifically, the forward phase sequence, the shutdown phase sequence, and the reverse phase sequence are selected and output sequentially; or, the reverse phase sequence, the shutdown phase sequence, and the forward phase sequence are selected and output sequentially.
[0006] Optionally, the mold temperature controller operation control system also includes: a phase sequence conversion detection module, an exhaust drive module, and an exhaust valve coil; The phase sequence conversion detection module is electrically connected to the phase sequence conversion module and is used to detect the phase sequence information of the phase sequence conversion module. The exhaust drive module is used to receive exhaust control commands from the user; The exhaust valve coil is used to control the opening and closing of the exhaust valve by gaining or losing power according to the phase sequence information and the user's exhaust control command.
[0007] Optionally, the mold temperature controller operation control system further includes: a motor operation control switch; the control module is electrically connected to the motor operation control switch; The motor operation control switch is connected in series between the phase sequence conversion module and the three-phase input terminal of the water pump motor to be controlled.
[0008] Optionally, the phase sequence conversion module includes: a position conversion switch; The input terminal of the position switching switch includes a first contact, a second contact, and a third contact; The output terminal of the position switching switch includes a fourth contact, a fifth contact, and a sixth contact; When the first contact is connected to the fourth contact, the second contact is connected to the fifth contact, and the third contact is connected to the sixth contact, the position switching switch outputs a positive phase sequence. When the first contact is disconnected from the fourth contact, the second contact is disconnected from the fifth contact, and the third contact is disconnected from the sixth contact, the position switching switch outputs a stop phase sequence. When any two of the first, second, and third contacts are swapped and connected to the fourth, fifth, and sixth contacts respectively, the position switching switch outputs a reverse phase sequence.
[0009] Optionally, the position switching switch may include a cam position switching switch or an electronic position switching switch.
[0010] Optionally, the phase sequence conversion module includes an electronic commutation unit.
[0011] Optionally, the phase sequence conversion detection module includes: a position detection switch or a position sensor; Alternatively, the phase sequence conversion detection module may include: a relay and a control unit; The control unit is used to detect the phase sequence information of the phase sequence conversion module in order to control the relay to be in an on / off state.
[0012] Optionally, the exhaust drive module includes a manual control switch; The manual control switch includes a push-button switch, a handle switch, a foot switch, or a reset switch.
[0013] Optionally, the exhaust control module includes a timer control switch; The timer control switch is used to automatically turn on after a set condition is met.
[0014] In a second aspect, the present invention also provides a mold temperature controller, which includes the mold temperature controller operation control system described in the first aspect above, and further includes: a water pump motor to be controlled, a heater and a cooler; The water pump motor drives the heat transfer medium to enter the mold water circuit from the inlet of the mold temperature controller for heat exchange.
[0015] In this embodiment of the invention, the input terminal of the phase sequence conversion module is electrically connected to a three-phase voltage source; the output terminal of the phase sequence conversion module is electrically connected to the input terminal of the heating control switch and the three-phase input terminal of the water pump motor to be controlled; the output terminal of the heating control switch is electrically connected to the heater; the heating control switch is electrically connected to the control module and is used to switch on and off according to the control command of the control module; the phase sequence conversion module is used to select one of the outputs—a forward phase sequence, a reverse phase sequence, and a stop phase sequence—so that the forward phase sequence drives the water pump motor to be controlled to rotate forward, the reverse phase sequence drives the water pump motor to be controlled to rotate in reverse, and the stop phase sequence drives the water pump motor to be controlled to stop. The system operates by sequentially selecting one of the forward phase sequence, the shutdown phase sequence, and the reverse phase sequence for output; or, sequentially selecting one of the reverse phase sequence, the shutdown phase sequence, and the forward phase sequence for output. This phase sequence conversion module is a disconnect-then-connect type, requiring the water pump to pass through a disconnected position during the forward / reverse switching process to avoid the simultaneous activation of the normal and reverse phase sequences. Furthermore, the phase sequence switching of the phase sequence conversion module does not affect the on / off state of the heating control switch. This avoids the need for additional interlocking mechanisms, control outputs, and corresponding wiring that would be required in existing systems using two forward / reverse contactors. This allows for forward and reverse rotation of the water pump within the mold temperature controller without affecting the heating function of the heater within the mold temperature controller.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0021] Figure 1 This is a schematic diagram of the structure of a mold temperature controller operation control system provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the mold temperature controller operation control system includes: a control module 10, a phase sequence conversion module 20, and a heating control switch 30; the input terminal of the phase sequence conversion module 20 is electrically connected to a three-phase voltage source; the output terminal of the phase sequence conversion module 20 is electrically connected to the input terminal of the heating control switch 30 and the three-phase input terminal of the water pump motor M to be controlled; the output terminal of the heating control switch 30 is electrically connected to the heater; the heating control switch 30 is electrically connected to the control module 10 and is used to switch on and off according to the control command of the control module 10. The phase sequence conversion module 20 is used to select one of the outputs: forward phase sequence, reverse phase sequence, and stop phase sequence, so that the forward phase sequence drives the water pump motor M under control to rotate forward, the reverse phase sequence drives the water pump motor M under control to rotate in reverse, and the stop phase sequence drives the water pump motor M under control to stop running. Among them, the forward phase sequence, the shutdown phase sequence, and the reverse phase sequence are selected to be output in sequence; or, the reverse phase sequence, the shutdown phase sequence, and the forward phase sequence are selected to be output in sequence.
[0022] In this embodiment, the input terminal of the phase sequence conversion module 20 is electrically connected to the three-phase voltage source, and the output terminal of the phase sequence conversion module 20 is electrically connected to the three-phase input terminal of the water pump motor M to be controlled. The phase sequence conversion module 20 can selectively output a forward phase sequence, a reverse phase sequence, and a stop phase sequence through position conversion. When the phase sequence conversion module 20 outputs a forward phase sequence, the output phase sequence of the three-phase voltage source is a forward phase sequence, which is output to the water pump motor M to be controlled, thereby driving the water pump motor M to rotate forward, and then driving the heat transfer medium to be delivered to the mold by the mold temperature controller. When the phase sequence conversion module 20 outputs a reverse phase sequence, the output phase sequence of the three-phase voltage source is a reverse phase sequence, which is output to the water pump motor M to be controlled, thereby driving the water pump motor M to rotate in reverse, and the water pump reverses to draw the heat transfer medium in the mold water circuit. When the phase sequence conversion module 20 outputs a stop phase sequence, the output phase sequence of the three-phase voltage source is a stop phase sequence, which is output to the water pump motor M to be controlled, thereby driving the water pump motor M to stop. It should be noted that the phase sequence conversion module 20 can selectively output the forward phase sequence, reverse phase sequence, and shutdown phase sequence through position conversion. Specifically, the forward phase sequence, shutdown phase sequence, and reverse phase sequence are selected and output sequentially; or, the reverse phase sequence, shutdown phase sequence, and forward phase sequence are selected and output sequentially. That is, the phase sequence conversion module 20 is a disconnect-then-connect type. The water pump motor M to be controlled must pass through the disconnect position during the switching process from forward to reverse to avoid the normal phase sequence and the reverse phase sequence being connected at the same time. At the same time, the phase sequence conversion module 20 does not affect the on / off state of the heating control switch 30 during the switching of different phase sequences. The control module 10 can be any of the following forms: PLC, mold temperature controller board, or microcontroller controller. This embodiment does not limit this type of controller. The control module 10 can output control commands to the heating control switch 30 according to the temperature during the real-time operation of the mold temperature controller, thereby controlling the on / off state of the heating control switch 30. The heating control switch 30 can be a relay or a contactor. This embodiment does not limit this type of controller. In this embodiment of the invention, the phase sequence conversion module 20 is a disconnect-then-connect type. The water pump must pass through the disconnect position during the switching process from forward to reverse rotation. This avoids the simultaneous connection of the normal phase sequence and the reverse phase sequence. At the same time, the phase sequence switching of the phase sequence conversion module does not affect the on / off state of the heating control switch. This avoids the need for interlocking mechanisms, control outputs and corresponding wiring that would be required in the existing method of using two forward and reverse contactors. In this way, the forward and reverse rotation of the water pump in the mold temperature controller is realized without affecting the heating function of the heater in the mold temperature controller.
[0023] Optionally, based on the above embodiments, the phase sequence conversion module 20 can be further refined. Figure 2 This is a schematic diagram of another mold temperature controller operation control system provided in an embodiment of the present invention, as shown below. Figure 2 As shown, the phase sequence conversion module 20 in the mold temperature controller operation control system includes: a position conversion switch 21; the input terminal of the position conversion switch 21 includes a first contact L1, a second contact L2 and a third contact L3; the output terminal of the position conversion switch 21 includes a fourth contact T1, a fifth contact T2 and a sixth contact T3; When the first contact L1 is connected to the fourth contact T1, the second contact L2 is connected to the fifth contact T2, and the third contact L3 is connected to the sixth contact T3, the position switch 21 outputs a positive phase sequence. When the first contact L1 is disconnected from the fourth contact T1, the second contact L2 is disconnected from the fifth contact T2, and the third contact L3 is disconnected from the sixth contact T3, the position switch 21 outputs a stop phase sequence. When any two of the first contact L1, the second contact L2, and the third contact L3 are swapped and correspond to the fourth contact T1, the fifth contact T2, and the sixth contact T3 respectively, the position switch 21 outputs a reverse phase sequence.
[0024] Specifically, when the first contact L1 is connected to the fourth contact T1, the second contact L2 is connected to the fifth contact T2, and the third contact L3 is connected to the sixth contact T3, the position switching switch 21 is in the first position, that is, the output phase sequence is positive, so that the output phase sequence of the three-phase voltage source is positive and output to the water pump motor M to be controlled, thereby driving the water pump motor M to be controlled to rotate forward; When the first contact L1 is disconnected from the fourth contact T1, the second contact L2 is disconnected from the fifth contact T2, and the third contact L3 is disconnected from the sixth contact T3, the position changeover switch 21 is in the second position, that is, the output stop phase sequence, so that the output phase sequence of the three-phase voltage source is the stop phase sequence, and outputs to the water pump motor M to be controlled, thereby driving the water pump motor M to be controlled to stop. When any two of the first contact L1, second contact L2, and third contact L3 are swapped, corresponding to the fourth contact T1, fifth contact T2, and sixth contact T3 respectively, the position switch 21 is in the third position, and the position switch 21 outputs a reverse phase sequence. This makes the output phase sequence of the three-phase voltage source reversed and output to the water pump motor M to be controlled, thereby driving the water pump motor M to be controlled to reverse. For example, in some embodiments, the first contact L1 and the second contact L2 are swapped, so the second contact L2 is connected to the fourth contact T1, the first contact L1 is connected to the fifth contact T2, and the third contact L3 is connected to the sixth contact T3, so the position switch 21 outputs a reverse phase sequence. In other embodiments, the first contact L1 and the third contact L3 are swapped, so the first contact L1 is connected to the sixth contact T3, the second contact L2 is connected to the fifth contact T2, and the third contact L3 is connected to the fourth contact T1, so the position switch 21 outputs a reverse phase sequence.
[0025] It is understood that the connection method of each contact in the above embodiment can be mechanical and / or electronic, and this embodiment does not limit this. The forward phase sequence, stop phase sequence and reverse phase sequence output by the position changeover switch 21 are selected one by one in sequence; or, the reverse phase sequence, stop phase sequence and forward phase sequence are selected one by one in sequence. The position changeover switch 21 is a disconnect-then-connect type switch. The water pump must pass through the disconnect position during the forward and reverse switching process. This avoids the simultaneous connection of the normal phase sequence and the reverse phase sequence. This avoids the need for interlocking mechanisms, control outputs and corresponding wiring that would be added by using two forward and reverse contactors in the existing method. In this way, the forward and reverse rotation of the water pump in the mold temperature controller is realized without affecting the heating function of the heater in the mold temperature controller.
[0026] Optional, continue to refer to Figure 2 The position switching switch 21 includes a cam position rotary switch or an electronic position switching switch.
[0027] The position switching switch 21 may include a cam position rotary switch; the cam position rotary switch is a mechanical rotary switch that relies on a rotating cam to drive multiple sets of contact connections to achieve multi-circuit switching; the electronic position switching switch may include an electronic position switching switch; the electronic position switching switch is an electronic rotary switch that uses a relay to drive multiple sets of contact connections to achieve multi-circuit switching; using an electronic position switching switch can improve the efficiency of phase sequence switching.
[0028] Optionally, in other embodiments, the phase sequence conversion module 20 includes an electronic commutation unit.
[0029] The electronic commutation unit is a motor phase sequence switching drive unit, which can be an inverter bridge composed of power switching transistors. The electronic commutation unit is electrically connected to the motor stator winding, receives the rotor position signal, and switches the energizing state of each phase winding of the motor according to the rotor position in a preset sequence (the preset sequence may include forward phase sequence, reverse phase sequence and stop phase sequence). The winding energizing phase sequence is changed alternately to form a rotating magnetic field that drives the rotor to rotate, thereby realizing the electronic commutation of the water pump motor M to be controlled. This avoids the need for interlocking mechanisms, control outputs and corresponding wiring that would be added by using two positive and negative contactors in the existing method. This enables the water pump inside the mold temperature controller to rotate in both directions without affecting the heating function of the heater inside the mold temperature controller.
[0030] Optionally, the above embodiments can be further optimized. Figure 3 This is a schematic diagram of another mold temperature controller operation control system provided in an embodiment of the present invention, as shown below. Figure 3 As shown, the mold temperature controller operation control system also includes: a phase sequence conversion detection module 40, an exhaust drive module 50, and an exhaust valve coil 60; Phase sequence conversion detection module 40 is electrically connected to phase sequence conversion module 20 and is used to detect the phase sequence information of phase sequence conversion module 20; exhaust drive module 50 is used to receive user exhaust control commands; exhaust valve coil 60 is used to control the opening and closing of exhaust valve according to the phase sequence information and user exhaust control commands.
[0031] Specifically, when the phase sequence conversion detection module 40 detects that the phase sequence information of the phase sequence conversion module 20 is a positive phase sequence or a stopped phase sequence, the exhaust valve coil 60 de-energizes according to the phase sequence information and the user's exhaust control command to control the exhaust valve to disconnect. When the phase sequence conversion detection module 40 detects that the phase sequence information of the phase sequence conversion module 20 is reversed, the exhaust drive module 50 receives the user's exhaust control command as an exhaust non-drive command. The exhaust valve coil 60 de-energizes according to the phase sequence information and the exhaust non-drive command to control the exhaust valve to open. At this time, the water pump motor M to be controlled reverses. In this way, when there is a leak in the mold water circuit, the water pump reverses to draw the heat transfer medium in the mold water circuit, which can reduce the heat transfer medium flowing out from the leak location. When the phase sequence conversion detection module 40 detects that the phase sequence information of the phase sequence conversion module 20 is reversed, the exhaust drive module 50 receives the user's exhaust control command as an exhaust drive command. The exhaust valve coil 60 is energized according to the phase sequence information and the exhaust drive command to control the exhaust valve to open, allowing air to enter the mold water circuit. Thus, during the reverse rotation of the water pump motor M, that is, during the reverse suction of the heat transfer medium in the mold water circuit, the incoming air replaces the extracted heat transfer medium, preventing the formation of a vacuum in the mold water circuit that hinders further drainage. In this way, the reverse water pump continuously draws the heat transfer medium in the mold water circuit back to the mold temperature controller. Thus, through the phase sequence conversion detection module 40, the exhaust drive module 50, and the exhaust valve coil 60, the mold water circuit evacuation function and the reverse suction leakage function are further added on the basis of the above embodiment.
[0032] Optionally, in some embodiments, reference continues to be made to... Figure 3 The phase sequence conversion detection module 40 includes a position detection switch. Specifically, the position detection switch can detect the phase sequence information of the phase sequence conversion module 20; specifically, when the position detection switch is in the closed state, it represents the detection state of the reverse phase sequence; when the position detection switch is in the open state, it represents the detection state of the forward phase sequence or the stop phase sequence; thus, the exhaust valve coil is energized and de-energized according to the phase sequence information and the user's exhaust control command to control the opening and closing of the exhaust valve; thereby realizing the mold water channel evacuation function and the reverse suction leakage function.
[0033] Alternatively, in some other embodiments, the phase sequence conversion detection module 40 includes: a relay and a control unit; the control unit is used to detect the phase sequence information of the phase sequence conversion module 20 to control the relay to be in an on / off state; specifically, if the phase sequence information detected by the control unit is a reverse phase sequence, the control unit controls the relay to close; the closed state of the relay represents the detection state of the reverse phase sequence; if the phase sequence information detected by the control unit is a forward phase sequence or a stopped phase sequence, the control unit controls the relay to open; the open state of the relay represents the detection state of the forward phase sequence or a stopped phase sequence; in this way, the exhaust valve coil is energized and de-energized according to the phase sequence information and the user's exhaust control command to control the opening and closing of the exhaust valve; thus realizing the mold water channel evacuation function and the reverse suction leakage function.
[0034] Optional, continue to refer to Figure 3 The exhaust drive module 50 includes a manual control switch; wherein the manual control switch includes a push-button switch, a handle switch, a foot switch, or a reset switch.
[0035] The manual control switch is used to receive human operation signals from the operator to trigger a switch signal. Correspondingly, when the switch signal is closed, it represents that the user's exhaust control command is an exhaust drive command; when the switch signal is open, it represents that the user's exhaust control command is an exhaust non-drive command. The manual control switch can be any of the following: push-button switch, handle switch, foot switch, or reset switch, or a combination of multiple switches can be used; there are no limitations on this. Optional, continue to refer to Figure 3 The exhaust drive module 50 includes a timer control switch; the timer control switch is used to automatically turn on after a set condition is met.
[0036] The exhaust drive module 50 includes a timer control switch. The timer control switch is used for timing monitoring and automatically opens and outputs a switch signal after the preset timing conditions are met. Correspondingly, when the switch signal is closed, it means that the user's exhaust control command is an exhaust drive command; when the switch signal is open, it means that the user's exhaust control command is an exhaust non-drive command. In this way, the exhaust valve coil controls the opening and closing of the exhaust valve according to the phase sequence information and the user's exhaust control command. This realizes the mold water channel evacuation function and the reverse suction leakage function.
[0037] Optionally, the above embodiments can be further refined. Figure 4 This is a schematic diagram of another mold temperature controller operation control system provided in an embodiment of the present invention, as shown below. Figure 4 As shown, the mold temperature controller operation control system also includes: a motor operation control switch 70; the control module 10 is electrically connected to the motor operation control switch 70; the motor operation control switch 70 is connected in series between the phase sequence conversion module 20 and the three-phase input terminal of the water pump motor M to be controlled.
[0038] Specifically, the motor operation control switch 70 can be a contactor, a relay, or a switch chip; this embodiment does not limit this. During the forward and reverse rotation of the water pump motor M to be controlled, the motor operation control switch 70 can be turned on and off under the control command of the control module 10, thereby controlling whether the motor stops running, avoiding abnormalities during operation, and thus improving the reliability of the mold temperature controller operation control.
[0039] Based on the same inventive concept, this invention also provides a mold temperature controller, which includes the mold temperature controller operation control system described in the above embodiments, and further includes: a water pump motor to be controlled, a heater, and a cooler; the water pump motor drives the heat transfer medium to enter the mold water circuit from the water inlet of the mold temperature controller for heat exchange. In some embodiments, before the water pump motor to be controlled reverses, the control module can control the cooler to cool the mold temperature controller, thereby satisfying the condition for the water pump motor to be controlled to reverse; in addition, since this embodiment includes the mold temperature controller operation control system of the above embodiments, it also has the beneficial effects of the above embodiments, which will not be repeated here.
[0040] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
