Description

An expandable hot runner temperature control box Technical Field

[0001] This utility model relates to the technical field of hot runner systems for injection molds, and in particular to an expandable hot runner temperature control box. Background Technology

[0002] Hot runner systems use heating to keep the plastic in the runner and gate in a molten state. The core components of a hot runner system are the hot runner heater and the hot runner temperature control box. The hot runner heater is installed in the hot runner mold to heat the mold. The hot runner heater is connected to the hot runner temperature control box, which controls the heating action of the hot runner heater. In industrial production, the hot runner temperature control box plays a crucial role in controlling the temperature of the hot runner system.

[0003] Among them, the Chinese utility model patent with patent number ZL202220190990.X and patent name: "An intelligent temperature control box for a hot runner system of injection molds" specifically discloses the following technical solution: An intelligent temperature control box for a hot runner system of injection molds includes a box body, a touch industrial display screen, an alarm light, and a control circuit board. The control circuit board is installed inside the box body, the touch industrial display screen is located at the front of the box body, and both the alarm light and the touch industrial display screen are connected to the control circuit board. A cooling fan is installed inside the box body, and the cooling fan has heat dissipation mesh holes on both sides.

[0004] It should be noted that the intelligent temperature control box used in the hot runner system of injection molds still has the following defects: Since the number of hot runner heaters that the hot runner temperature control box can connect to is fixed, that is, the hot runner temperature control box cannot be expanded according to different industrial production scale requirements. When the number of hot runner heaters that need to be controlled in the hot runner system exceeds the number that the hot runner temperature control box can connect to, it is necessary to add another hot runner temperature control box to control the excess hot runner heaters. Multiple hot runner temperature control boxes independently control the hot runner heaters they are connected to, which is not conducive to the centralized and unified management and display of all hot runner heaters in the hot runner mold.

Detailed Implementation

[0026] The present invention will now be described in conjunction with specific embodiments.

[0027] Example 1, as shown in Figures 1 to 5, is an expandable hot runner temperature control box, which includes a temperature control box unit 1, a box body 2, an internal cavity 3 formed in the box body 2, a front panel 21 and a back panel 22, and a touch screen 4 mounted on the front panel 21.

[0028] As shown in Figures 3 to 5, an industrial computer 5 is embedded in the cavity 3 of the temperature control box unit 1. The rear panel 22 of the temperature control box unit 1 is equipped with a heater connection interface 6 and an RJ45 network port 7. The touch screen 4, the heater connection interface 6, and the RJ45 network port 7 are electrically connected to the industrial computer 5, respectively.

[0029] Furthermore, as shown in Figures 1 to 4, the expandable hot runner temperature control box includes two temperature control box units 1, the box bodies 2 of the two temperature control box units 1 are stacked one on top of the other, and the box bodies 2 of the two temperature control box units 1 are connected by a connecting bracket.

[0030] Furthermore, the RJ45 network ports 7 of the two individual temperature control boxes 1 are connected via network cables.

[0031] For the expandable hot runner temperature control box in this embodiment, the two temperature control box units 1 arranged in an upper and lower layer are connected by a connecting bracket to form a whole.

[0032] When the expandable hot runner temperature control box of this embodiment is working, the heater connection interface 6 of each temperature control box unit 1 is electrically connected to the hot runner heater of the hot runner mold. During operation, the working parameters of the hot runner heater are transmitted to the industrial computer 5 through the heater connection interface 6. The industrial computer 5 then displays the working parameters of the hot runner heater in real time through the touch screen 4.

[0033] It should be emphasized that in this embodiment, the RJ45 network ports 7 of the two temperature control box units 1 are connected by a network cable. At this time, the two temperature control box units 1 are connected to form a local area network, and the two temperature control box units 1 communicate with each other through the network cable connected to the RJ45 network ports 7. During operation, the staff can use the touch screen 4 of one of the temperature control box units 1 to centrally manage and display all the hot runner heaters in the hot runner mold, so as to improve the convenience of use.

[0034] In summary, the expandable hot runner temperature control box of this embodiment has the advantages of novel structural design, convenient use, good expandability and strong adaptability through the above structural design.

[0035] Example 2, as shown in Figures 1 to 5, differs from Example 1 in that: each temperature control box 1 is further provided with a left end shell 23 and a right end shell 24, and the connecting bracket includes a left bracket 81 and a right bracket 82.

[0036] The upper and lower ends of the left bracket 81 are screwed to the left end shell 23 of the corresponding side temperature control box 1, and the upper and lower ends of the right bracket 82 are screwed to the right end shell 24 of the corresponding side temperature control box 1.

[0037] Example 3, as shown in Figures 1 to 5, differs from Example 2 in that: the left end shell 23 and the right end shell 24 are respectively provided with convection heat dissipation holes 25 that communicate with the accommodating cavity 3 of the corresponding temperature control box unit 1.

[0038] Each temperature control box 1 is equipped with an outward-flowing cooling fan 91 in its accommodating cavity 3, and the cooling fan 91 is electrically connected to the industrial computer 5 of the corresponding temperature control box 1.

[0039] It should be explained that the convection cooling holes 25 on the left end shell 23 and the right end shell 24 are aligned. When the cooling fan 91 is started, the external airflow enters into the accommodating cavity 3 and flows through the entire accommodating cavity 3 to achieve convection cooling of the industrial computer 5 inside the accommodating cavity 3.

[0040] Example 4, as shown in Figures 3 to 5, differs from Example 1 in that: each temperature control box unit 1 is also equipped with a buzzer 92 on its back panel 22, and each buzzer 92 is electrically connected to the industrial computer 5 of the corresponding temperature control box unit 1.

[0041] The buzzer 92 in this embodiment is used to provide an alarm reminder. When the hot runner heater connected to the temperature control box unit 1 or the industrial computer 5 itself malfunctions, the buzzer 92 will sound an alarm to remind the staff to perform maintenance operations in a timely manner.

[0042] Example 5, as shown in Figures 3 to 5, differs from Example 1 in that: the back panel 22 of each temperature control box 1 is also equipped with an air switch 93, and each air switch 93 is electrically connected to the industrial computer 5 of the corresponding temperature control box 1.

[0043] For the air switch 93 in this embodiment, when the hot runner heater connected to the temperature control box unit 1 or the industrial computer 5 itself malfunctions, the air switch 93 automatically disconnects and shuts down the temperature control box unit 1 to achieve the abnormal protection function.

[0044] 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.
