Description

Technical Field

[0001] The utility model relates to the field of die casting mould technology, in particular to a die casting mould for forming a movement flange. Background Art

[0002] Infrared thermal imagers, the industry's leading infrared thermal imaging technology, are different from traditional cameras and monitoring equipment. They can capture images of heat sources at night. Infrared thermal imagers have been widely used in smart security, infrared temperature measurement, outdoor night vision, automatic driving, smart life, Internet of Things, fire rescue, police law enforcement and other industries and fields.

[0003] The movement is an important part of the infrared thermal imager. The movement needs to be supported and installed by the movement flange. Therefore, the movement flange must not only meet the strength requirements of the support, but also require each design angle to accurately meet the imaging requirements. For this reason, the movement flange of the current infrared thermal imager is generally formed by metal die-casting, such as aluminum ADC12. The die-casting molding of the movement flange of the infrared thermal imager requires a die-casting mold. The main structure of the die-casting mold currently used for die-casting the movement flange of the infrared thermal imager includes a lower mold and an upper mold; the lower mold includes a lower mold seat, a lower mold plate, a lower mold core and an ejection mechanism. The lower mold plate is arranged on the lower mold seat, the lower mold core is arranged on the lower mold plate, and the ejection mechanism is arranged on the lower mold seat; the upper mold can be set up and down directly above the lower mold through the precise positioning of the guide column during work. The upper mold includes an upper mold plate, an upper mold core and a casting port. The upper mold core is arranged on the upper mold plate and is matched with the lower mold core up and down to form a cavity. The casting port is arranged on the upper mold plate and communicates with the cavity.

[0004] However, since there are many models and specifications of infrared thermal imagers, different models of infrared thermal imagers use different movement flanges, and these different movement flanges have certain differences in their internal and external structures. The above die-casting mold can only perform die-casting molding for one type of movement flange. When molding other types of movement flanges, it is necessary to replace the lower mold core and the upper mold core, or even replace the die-casting mold as a whole, resulting in poor versatility of the die-casting mold and increased production costs. Therefore, it is necessary to optimize and improve the existing die-casting mold. Utility Model Content

[0039] In this embodiment, the upper surface of the lower mold plate 12 is designed with a lower concave cavity 121, and the lower mold core 13 is embedded in the lower concave cavity 121 and fixedly connected to the lower mold plate 12 by a first bolt (not shown in the figure). The structure is simple and easy to disassemble and assemble. In addition, the contour of the lower concave cavity 121 is a rectangular parallelepiped, and the corresponding contour of the lower mold core 13 is also a rectangular parallelepiped. The upper surface of the lower mold core 13 is designed with a limit platform 132 at each corner, and the lower mold core 13 is provided with a plurality of lower cooling channels 133 for injecting coolant for cooling. The ejection mechanism 14 includes a bottom plate 141, a panel 142 and a plurality of ejector pins 143. The panel 142 is superimposed on the surface of the bottom plate 141 and can be movably arranged up and down with the bottom plate 141; the plurality of ejector pins 143 extend vertically, and the lower end of each ejector pin 143 is clamped and fixed between the bottom plate 141 and the panel 142. The bottom of the lower mold core insert 15 is fixedly connected to the lower mold plate 12 by a second bolt 16, and has a simple structure and is easy to disassemble and assemble. In addition, the outer contour of the lower mold core insert 15 is square, and the corresponding lower mold core insert hole 131 is also square, and the lower mold core insert holes 131 are arranged side by side and spaced apart. The aforementioned lower mold core insert 15 is arranged in each lower mold core insert hole 131, so as to simultaneously form two movement flanges 30. In addition, a diverter cone 17 is arranged on the upper surface of the lower mold plate 12.

[0040] The upper mold 20 is precisely positioned by the guide column 40 during operation and can be movably set up and down just above the lower mold 10. The upper mold 20 includes an upper mold plate 21, an upper mold core 22 and a casting port 23. The upper mold core 22 is arranged on the upper mold plate 21 and is matched with the lower mold core 13 up and down. The casting port 23 is arranged on the upper mold plate 21; the upper and lower surfaces of the upper mold core 22 are penetrated by upper inner mold core insert holes 221, and an upper outer mold core insert 24 is detachably placed in the upper inner mold core insert hole 221. A mounting hole 241 is formed through the upper and lower surfaces, and the longitudinal section of the mounting hole 241 is T-shaped. An upper inner mold core insert 25 is removably placed in the mounting hole 241. The longitudinal section of the upper inner mold core insert 25 is T-shaped and is compatible with the mounting hole 241. The upper inner mold core insert 25, the upper outer mold core insert 24 and the lower mold core insert 15 are combined to form a cavity 201 that is compatible with the movement flange 30. The casting port 23 is connected to the cavity 201, and the ejector pin 141 of the ejection mechanism 14 extends into the cavity 201 from bottom to top.

[0041] In this embodiment, the lower surface of the upper mold plate 21 is designed with an upper cavity 211, and the upper mold core 22 is embedded in the upper cavity 211 and fixedly connected to the upper mold plate 21 by a third bolt 26.

[0042] The working principle of this embodiment is described in detail as follows:

[0043] First, the upper mold 20 and the lower mold 10 are closed together. After the molds are closed, liquid metal or semi-liquid metal is injected into the cavity 201 from the casting port 23. Under the action of high pressure, the liquid metal or semi-liquid metal is filled into each cavity 201 at a high speed, and quickly solidifies under high pressure to obtain the movement flange 30. After the liquid metal or semi-liquid metal in the cavity 201 solidifies, the upper mold 20 is moved upward relative to the lower mold 10 to open the mold. When the upper mold 20 moves upward into place, the ejection mechanism 14 is moved upward by an external driving mechanism, so that each movement flange 30 is ejected upward by a plurality of ejector pins 143 and separated from the lower mold core insert 15. At this time, the movement flange 30 can be taken out.

[0044] The design focus of the utility model is that by detachably placing a lower core insert in the lower core insert hole, detachably placing an upper outer core insert in the upper core insert hole, and detachably placing an upper inner core insert in the matching mounting hole, when forming different types of movement flanges, the lower core insert, the upper outer core insert and the upper inner core insert can be replaced as needed, without replacing the lower core and the upper core, or even replacing the die-casting mold as a whole, thereby effectively enhancing the versatility of the die-casting mold, helping to reduce production costs and bringing convenience to production operations.

[0045] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
