However, external dust will also enter the electric box along with the air, and adhere to the surface of the control elements; with the accumulation of time, the dust accumulated on the control elements will affect its normal operation and reduce its service life.

[0003] It should be noted that the above content is only used to assist understanding of the technical scheme of the utility model, and does not represent that the above content is prior art. UTILITY MODEL CONTENT

[0004] The main purpose of the utility model is to provide an injection molding machine electric box, which can maintain the heat dissipation effect while reducing the influence of dust on the control elements in the electric box.

[0030] Generally, the inside of the injection molding machine electric box is divided into a main electric box chamber and a drive box chamber by a partition plate. The main electric box chamber contains electrical components that supply electrical energy to the injection molding machine. The drive box chamber is provided with control components of the power unit of the injection molding machine. The control components are the main heat generating components in the electric box. In order to avoid the accumulation of heat emitted by the control components and cause the surrounding environment temperature to be too high to work normally, or even damage; it is usually necessary to provide a ventilation hole on the side of the electric box. The outside air is introduced into the inside of the electric box through the ventilation hole by using a cooling fan. The heat of the control components is carried away by the air flow to achieve the purpose of cooling the control components. However, the external dust will also enter the inside of the electric box along with the air, and adhere to the surface of the control components. With the accumulation of time, the dust accumulated on the control components will affect its normal operation and reduce its service life.

[0031] In order to solve the above technical problems, the present application provides an injection molding machine electric box.

[0032] Please refer to Figures 1-4 In an embodiment of the present application, the electric box 100 in the injection molding machine electric box is arranged at the bottom of the injection molding machine (not shown in the drawing);

[0033] Specifically, the electric box 100 comprises:

[0034] The main electric box chamber 200 contains electrical components 210 that supply electrical energy to the injection molding machine;

[0035] The drive box chamber 300 is provided with control components 310 of the power unit of the injection molding machine;

[0036] The main electric box chamber 200 and the drive box chamber 300 are spaced apart by the mounting plate 400 to form a heat dissipation channel 500, and the heat dissipation part 311 of the control component 310 is arranged in the heat dissipation channel 500.

[0037] It can be understood that, for the control element 310, there is a heat dissipation part 311 with relatively high heat dissipation requirement and a non-heat dissipation part 312 with relatively low heat dissipation requirement, and the air flow is mainly for cooling the heat dissipation part 311 of the control element 310; based on the above reasons, the technical scheme of the utility model forms a heat dissipation channel 500 between the main electric box chamber 200 and the driving box chamber 300 through the installation plate 400, and the heat dissipation part 311 of the control element 310 is arranged in the heat dissipation channel 500; so that the air flowing in the heat dissipation channel 500 can only contact the heat dissipation part 311 of the control element 310, and the non-heat dissipation part 312 of the control element 310 cannot contact the flowing air due to being arranged in the driving box chamber 300, so that the dust in the flowing air can only adhere to the surface of the heat dissipation part 311 of the control element 310, thereby realizing the effect of maintaining the heat dissipation and cooling effect while reducing the influence of dust on the control element 310 in the electric box 100.

[0038] The control element 310 further comprises a driver (not shown in the figure), and the driver is cooled by the heat dissipation part 311 and arranged in the driving box chamber 300. Since the driver in the control element 310 is the main heat source, the application mainly cools the driver.

[0039] As a preferred scheme of the above embodiment, the heat dissipation part 311 of the control element 310 penetrates through the installation plate 400, and the control element 310 is arranged on the installation plate 400. In this way, a through hole part (not shown in the figure) is arranged on the installation plate 400, so that the heat dissipation part 311 of the control element 310 can be arranged in the heat dissipation channel 500 through the through hole part, to ensure the smooth implementation of the technical scheme of the application.

[0040] Further, a sealing layer (not shown in the figure) is arranged at the connection between the non-heat dissipation part 312 of the control element 310 and the installation plate 400. In this way, the flowing air in the heat dissipation channel 500 is prevented from flowing into the driving box chamber 300 through the connection between the non-heat dissipation part 312 of the control element 310 and the installation plate 400, so that the dust in the flowing air adheres to the surface of the non-heat dissipation part 312 of the control element 310. The sealing layer can be a rubber ring, which is arranged around the outer periphery of the through hole part.

[0041] As a preferred scheme of the above embodiment, reference is made to the accompanying Figure 3The mounting plate 400 comprises a first mounting plate 410 and a second mounting plate 420, the first mounting plate 410 constituting a side wall of the main electric box chamber 200, and the second mounting plate 420 constituting a side wall of the drive box chamber 300, the first mounting plate 410, the second mounting plate 420 and the bottom plate of the electric box 100 constituting the heat dissipation channel 500. In this way, the first mounting plate 410, the second mounting plate 420 and the bottom plate of the electric box 100 are combined with each other to form the heat dissipation channel 500, so as to ensure the mutual isolation between the main electric box chamber 200 and the drive box chamber 300 and the heat dissipation channel 500.

[0042] Further, the mounting plate 400 further comprises a sealing plate 530, which is arranged at the top of the heat dissipation channel 500. In this way, the sealing plate 530 is arranged at the top of the heat dissipation channel 500, so as to avoid the flowing air from flowing into the main electric box chamber 200 or the drive box chamber 300 from the top of the heat dissipation channel 500.

[0043] Further, the sealing plate 530 is detachably connected to the first mounting plate 410 and the second mounting plate 420. In this way, considering that dust will adhere to the heat dissipation channel 500 over time, affecting the smoothness of air flow, the sealing plate 530 is detachably connected, so that the operating personnel can clean the inside of the heat dissipation channel 500 by detaching the sealing plate 530, to ensure that the inside of the heat dissipation channel 500 is clean and dust-free. As to the connection mode between the sealing plate 530 and the first mounting plate 410 and the second mounting plate 420, threaded connection or buckle connection can be adopted, which is not limited in the present application.

[0044] As a preferred scheme of the above embodiment, the bottom plate of the electric box 100 is provided with an air inlet 510, and external air enters the heat dissipation channel 500 through the air inlet 510; the side wall of the electric box 100 is provided with an air outlet 520, and the heat dissipation channel 500 is communicated with the air outlet 520. In this way, external air enters the inside of the heat dissipation channel 500 through the air inlet 510, and then is discharged from the heat dissipation channel 500 through the air outlet 520, so that flowing air is formed in the inside of the heat dissipation channel 500, and the flowing air is used to cool and dissipate heat of the heat dissipation part 311 of the drive element in the heat dissipation channel 500, which is simple in structure and high in practicability.

[0045] The air inlet 510 and / or the air outlet 520 is provided with a heat dissipation fan 540. In this way, the heat dissipation fan 540 is used as a power source to drive air to enter the heat dissipation channel 500, so that flowing air is formed in the heat dissipation channel 500. In the present embodiment, the heat dissipation fan 540 is arranged at the air outlet 520 of the heat dissipation channel 500.

[0046] Further, the air inlet 510 and / or the air outlet 520 is provided with a filter structure (not shown in the drawings). In this way, the filter structure is used to filter dust in the air to avoid the dust entering the heat dissipation channel 500 along with the air and adhering to the heat dissipation part 311 of the control element 310, further reducing the influence of the dust on the control element 310.

[0047] As a preferred solution of the above embodiment, reference is made to the accompanying drawings Figure 4 The main electric box chamber 200 and the drive box chamber 300 are connected through the threading groove 600, so that the electric elements 210 between the main electric box chamber 200 and the drive box chamber 300 are electrically connected, and the threading groove 600 is separated from the heat dissipation channel 500. In this way, the connecting line is passed through the threading groove 600 to ensure that the electric elements 210 in the main electric box chamber 200 and the drive elements in the drive box chamber 300 can be electrically connected to ensure the normal operation of the injection molding machine; at the same time, the threading groove 600 is required to be separated from the heat dissipation channel 500 to avoid the dust in the flowing air flowing to the surface of the electric elements 210 in the main electric box chamber 200 or the drive elements in the drive box chamber 300 through the threading groove 600.

[0048] It should be noted that other contents of the injection molding machine electric box disclosed in the utility model are prior art, which will not be described here.

[0049] The above is only an optional embodiment of the utility model, and does not limit the patent range of the utility model, and any direct / indirect application of the utility model in other related technical fields is included in the patent protection range of the utility model.
