Description

Technical Field

[0001] This utility model relates to the technical field of needle valve hot runner systems, and in particular to a multi-group needle valve touch-controlled timing displacement controller for hot runner systems. Background Technology

[0002] A needle valve hot runner is a type of hot runner system that controls the opening and closing of the gate through the mechanical action of a needle valve. Specifically, the working principle of a needle valve hot runner is as follows: The injection molding machine sends an injection signal, which drives the solenoid valve that controls the compressed air. The solenoid valve changes the direction of the compressed air flow inside the cylinder that drives the needle valve, thereby pushing the hot runner piston to open the gate. After the plastic is injected into the mold cavity, it is held under pressure. After the pressure holding is completed, the injection signal is interrupted, the solenoid valve reverses its action and the direction of the compressed air flow changes. At this time, the piston closes and seals the gate.

[0003] In a needle valve hot runner system, the needle valve is controlled by a corresponding timing controller. Among them, the utility model patent with patent number ZL202022907845.2 and patent name: "A reinforced hot runner timing injection controller" specifically discloses the following technical solution: A reinforced hot runner timing injection controller includes a body, and a touch screen is provided on one side of the body.

Detailed Implementation

[0029] The present invention will now be described in conjunction with specific embodiments.

[0030] Example 1: A multi-group needle valve touch-controlled timing displacement controller for a hot runner system. The hot runner system includes a hot runner mold (not shown in the figure) and several needle valves (not shown in the figure) movably installed at the gate position of the hot runner mold. Each needle valve is driven by a driving component (not shown in the figure), which is a cylinder or a hydraulic cylinder, and each driving component is equipped with a solenoid valve (not shown in the figure).

[0031] Among them, such as Figures 1 to 3 As shown, the multi-group needle valve touch timing displacement controller of the hot runner system includes a controller housing 1. The controller housing 1 has a housing cavity 11 formed inside. The controller housing 1 is provided with a front panel 12 located in front of the housing cavity 11 and a rear panel 13 located behind the housing cavity 11.

[0032] Furthermore, such as Figure 1 Congratulations Figure 3 As shown, the control circuit board 2 is embedded in the housing cavity 11, and the front panel 12 is equipped with a touch screen 3, which is electrically connected to the control circuit board 2.

[0033] Furthermore, such as Figure 2 As shown, the back panel 13 is equipped with an injection molding machine connection interface 4, which is electrically connected to the control circuit board 2.

[0034] In addition, such as Figure 3 As shown, a relay group 5 is also embedded in the housing cavity 11. The relay group 5 includes several relays 51 that are electrically connected to the solenoid valves of the corresponding driving components during use. Each relay 51 is electrically connected to the control circuit board 2.

[0035] And also, such as Figure 2 As shown, the hot runner system multi-group needle valve touch timing displacement controller also includes a displacement sensor (not shown in the figure) installed on the injection molding machine and used to monitor the real-time position of the injection molding machine screw. The back panel 13 of the controller housing 1 is equipped with a monitoring connection interface 6 that is electrically connected to the displacement sensor during use. The monitoring connection interface 6 is electrically connected to the control circuit board 2.

[0036] It should be explained that the displacement sensor in this embodiment can be a magnetic grating ruler; of course, the magnetic grating ruler does not constitute a limitation on this embodiment, that is, the displacement sensor in this embodiment can also adopt other structural forms.

[0037] In this embodiment of the hot runner system, the multi-group needle valve touch-sensitive timing displacement controller operates by connecting the injection molding machine to the injection molding machine via signal lines. When the injection molding machine performs an injection operation, the injection molding machine's controller feeds back signals to the control circuit board 2 via the injection molding machine connection interface 4. The control circuit board 2 then controls the operation of each relay 51 according to a timing sequence, thereby controlling the timing of each driving component in the hot runner system to achieve the purpose of needle valve timing control. Therefore, the multi-group needle valve touch-sensitive timing displacement controller in this embodiment of the hot runner system can achieve linkage with the injection molding machine, effectively improving the control accuracy of the injection molding process.

[0038] During the process of driving the needle valve, the multi-group needle valve touch timing displacement controller of the hot runner system in this embodiment monitors the position of the injection molding machine screw in real time through the displacement sensor, so as to achieve accurate coordination between the needle valve action and the screw action, so as to avoid problems such as glue leakage or waste edge during injection molding.

[0039] In summary, the multi-group needle valve touch-controlled timing displacement controller of the hot runner system in this embodiment has the advantage of novel structural design through the above structural design. On the one hand, it can realize the displacement monitoring function, and on the other hand, it can be linked with the injection molding machine.

[0040] Example 2, as Figures 1 to 3As shown, the difference between this embodiment 2 and embodiment 1 is that a power supply 71 is also embedded in the housing cavity 11. The power supply 71 is electrically connected to the control circuit board 2, and the power supply 71 is provided with a power line 72 extending to the outside of the controller housing 1.

[0041] When the multi-group needle valve touch timing displacement controller of the hot runner system in this embodiment 2 is working, the power cord 72 is connected to the mains power, and the power supply 71 supplies power to the control circuit board 2.

[0042] Example 3, as Figure 1 and Figure 2 As shown, the difference between this embodiment 3 and embodiment 1 is that: the back panel 13 is provided with a heat dissipation vent 131, and the housing cavity 11 is fitted with a cooling fan 8 that blows air toward the heat dissipation vent 131.

[0043] The lower end of the front panel 12 is provided with a heat dissipation air inlet 121 that communicates with the housing cavity 11.

[0044] When the multi-group needle valve touch timing displacement controller of the hot runner system in this embodiment 6 is working, the control circuit board 2 controls the cooling fan 8 to start. Under the driving action of the cooling fan 8, the external cold air enters the housing cavity 11 through the heat dissipation air inlet 121 of the front panel 12, and the heat dissipation air is finally discharged through the heat dissipation air outlet 131 of the rear panel 13. When the heat dissipation air passes through the housing cavity 11, the heat dissipation air dissipates heat on the control circuit board 2.

[0045] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
