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

[0013] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-6 A forming mold for the frame of a magnesium alloy die casting production domain controller includes a fixed mold plate 1 and a moving mold plate 2, and also includes a uniform die casting mechanism 3 and a demolding mechanism 4. The template 1 is fixedly connected to the shaping base plate of the die-casting machine; The moving template 2 is fixedly connected to the moving base plate of the die-casting machine; a sprue 11 for inputting molten metal is provided on the right side of the fixed template 1; A fixing plate 12 is fixedly installed on the left end of the template 1; a first forming groove 13 is provided in the middle of the fixing plate 12 for forming the controller frame body 5. The right end of the moving template 2 is fixedly installed with the main forming plate 21; the right end of the fixed main forming plate 21 is provided with a second forming groove 22 for cooperating with the first forming groove 13 to perform forming operations; A uniform die-casting mechanism 3 is installed between the fixed template 1 and the moving template 2 to ensure uniform forming of the controller's inner frame body 5; The uniform die-casting mechanism 3 includes a positioning component 31, a flow-diverting component 32, and an exhaust component 33; the positioning component 31 is connected to the fixed template 1 and the moving template 2; the flow-diverting component 32 is connected to the fixed template 1 and the moving template 2; and the exhaust component 33 is connected to the fixed template 1. A demolding mechanism 4 for demolding the controller's inner frame body 5 is installed on the left side of the moving template 2; In this invention, the die-casting machine controls the moving template 2 to move toward the fixed template 1, the fixed plate 12 and the fixed main forming plate 21 come into contact and abut against each other, and under the action of the positioning component 31, the first forming groove 13 and the fixed main forming plate 21 fit tightly together; finally, the first forming groove 13 and the second forming groove 22 form a forming cavity. Subsequently, the injection mechanism of the die-casting machine injects molten metal into the sprue 11 at a set speed and pressure, so that the molten metal enters the first forming groove 13 and the fixed main forming plate 21; and under the combined action of the first forming groove 13, the second forming groove 22 and the diversion component 32, the forming operation of the controller frame body 5 is realized. Furthermore, during the die-casting process, the venting assembly 33 will also expel the gas from the molding cavity; After filling is complete, the injection mechanism of the die-casting machine maintains pressure until the molten metal in the molding cavity is completely solidified; Subsequently, the die-casting machine drives the moving template 2 to separate from the fixed template 1. The injection mechanism of the die-casting machine separates synchronously with the moving template 2, so that the controller frame body 5 remains in the second forming groove 22 and separates from the first forming groove 13. As the moving template 2 moves away from the fixed template 1, the demolding mechanism 4 will also control the controller frame body 5 to perform demolding. Then, the unloading robot will remove the controller frame body 5. The cooperation of positioning component 31 and diversion component 32 prevents complex contour parts of the controller frame body 5 from sticking to the molding cavity, thereby improving the demolding quality; the exhaust component 33 enables the device to discharge the waste gas generated during molding in a timely manner, further improving the die-casting quality of the controller frame body 5.
[0014] Example 2: In some embodiments, such as Figures 1-6 As shown, in a preferred embodiment of the present invention, the positioning component 31 includes positioning pins 311 and positioning pin sleeves 312; a plurality of positioning pins 311 are fixedly installed in a rectangular array on the left end of the fixed template 1; a plurality of positioning pin sleeves 312 are fixedly installed in a rectangular array at equal intervals on the right end of the moving template 2; the positioning pins 311 and the positioning pin sleeves 312 are inserted into each other. Furthermore, the positioning pin 311 and the positioning pin sleeve 312 correspond one-to-one, and the positioning pin 311 has a guide slope on the side near the positioning pin sleeve 312; The diversion component 32 includes positioning protrusions 324; multiple positioning protrusions 324 are fixedly installed in a rectangular array on the right end of the moving template 2; multiple positioning grooves 325 that cooperate with and insert into the positioning protrusions 324 are provided in a rectangular array on the left end of the fixed template 1. A pouring channel 321 is provided on the lower side of the template 1; The upper side of the template 1 is symmetrically provided with slag bag forming grooves 322 at the front and back; Overflow grooves 323 are symmetrically provided on the front and rear sides of the middle part of the template 1; The refractory diversion channel 321 is connected to the gating system 11; The exhaust assembly 33 includes a diversion valve 331, a first main diversion pipe 332, a second main diversion pipe 333, a third main diversion pipe 334, and a secondary diversion pipe 335; the diversion valve 331 is fixedly installed on the upper end of the fixed template 1; the input end of the diversion valve 331 is connected to the air pump through an air pipe; the diversion valve 331 is provided with multiple output ends; one end of the first main diversion pipe 332, the second main diversion pipe 333, and the third main diversion pipe 334 are all fixedly connected to the output end of the diversion valve 331; Multiple secondary diversion pipes 335 are fixedly installed on the upper, front and rear sides of the fixed template 1; The other end of the first main branch pipe 332 is connected to the upper secondary branch pipe 335; The other end of the second main branch pipe 333 is connected to the rear secondary branch pipe 335; the other end of the third main branch pipe 334 is connected to the front secondary branch pipe 335. In this invention, as the moving template 2 moves toward the fixed template 1, the positioning pin 311 will be aligned and inserted with the positioning pin sleeve 312, so that the first forming groove 13 and the fixed main forming plate 21 are tightly fitted; thereby, the first forming groove 13 and the second forming groove 22 form a forming cavity. Subsequently, the injection mechanism of the die-casting machine injects the molten metal into the gating 11 at a set speed and pressure, so that the molten metal enters the first forming groove 13 and the fixed main forming plate 21; then the molten metal moves along the gating 11 into the casting distribution groove 321, and is evenly injected into the forming cavity through the casting distribution groove 321. The molten metal continues to flow in the forming cavity to the slag forming groove 322 to form a slag bag; At the same time, the air pump injects gas into the molding cavity through the diversion valve 331 along the first main diversion pipe 332, the second main diversion pipe 333, the third main diversion pipe 334 and the secondary diversion pipe 335, thereby discharging the gas in the molding cavity outward along the slag bag molding groove 322. Furthermore, when the molten metal flows into the overflow tank 323, it forms an overflow block, thereby ensuring that the molten metal fills the molding cavity evenly, ensuring the integrity and uniformity of the die-casting. After filling, the injection mechanism of the die-casting machine maintains pressure until the molten metal in the molding cavity is completely solidified.
[0015] Example 3: In some embodiments, such as Figure 1 As shown, in a preferred embodiment of the present invention, the demolding mechanism 4 includes a top plate 41 and ejector pins 42; the top plate 41 is slidably mounted on the left side of the moving template 2; a plurality of ejector pins 42 are also fixedly mounted on the right end of the top plate 41; and a plurality of ejection holes that cooperate and slide with the ejector pins 42 are also provided on the fixed main forming plate 21. The top plate 41 is fixedly connected to the ejection mechanism of the die-casting machine; In this invention, after the fixed template 1 and the moving template 2 are separated, the ejection mechanism of the die casting machine controls the top plate 41 to move horizontally to the right. During the movement, the ejector pin 42 will eject the controller frame body 5 through the ejection hole opened on the fixed main forming plate 21.
