[0002] With the continuous advancement of the metal products industry, the metal processing molds used for forming and blanking have also been continuously evolving. The mold is usually composed of two parts: the upper mold and the lower mold. During the manufacturing process of aluminum alloy workpieces, the aluminum alloy workpiece is usually placed between the upper mold and the lower mold. After placement, the upper mold and the lower mold are closed by pressure to extrude the aluminum alloy workpiece into shape.

[0031] like Figure 3-Figure 6As shown, the upper mold cooling mechanism includes a closing plate 71, a material guide tube 72, an elastic member 73, a liquid circulation channel 74 and an upper liquid outlet pipe 75. The upper inner portion of the upper forming platen 52 is connected to a closing plate 71, and the closing plate 71 can close the entire upper cooling chamber 53. A plurality of material guide tubes 72 are evenly spaced and connected to the upper mold 5. An elastic member 73 is connected between the material guide tube 72 and the upper mold 5. The elastic member 73 is a return spring. A liquid circulation channel 74 is provided in the material guide tube 72. The top end of the liquid circulation channel 74 is connected to the upper mold liquid storage chamber 51. The bottom end of the liquid circulation channel 74 is connected to the upper liquid outlet pipe 75. The upper liquid outlet pipe 75 and the end are connected to the upper cooling chamber 53. Cooling liquid is stored in the upper mold liquid storage chamber 51, and the cooling liquid can flow into the upper cooling chamber 53 through the liquid circulation channel 74 and the upper liquid outlet pipe 75.

[0032] like Figure 3-Figure 6 As shown, the lower mold cooling mechanism includes a lower liquid outlet pipe 81, an annular piston block 82, a connecting frame 83 and an elastic member 84. The lower mold liquid storage chamber 63 is slidably connected to the annular piston block 82.

[0033] When it is necessary to extrude aluminum alloy parts, this device can be used. When in use, the template 100 is first moved between the upper mold 5 and the lower mold 6. After placement, the telescopic rod of the hydraulic cylinder 3 can be controlled to extend to drive the moving platform 4 to move downward. When the moving platform 4 moves downward, it will drive the upper mold 5 to move downward. When the upper mold 5 moves downward, it will press on the template 100 and then extrude the template 100. The lower forming plate 61 and the upper forming plate 52 cooperate to extrude the template 100. After the upper forming plate 52 moves down to extrude the template 100, the upper forming plate 52 no longer moves. At this time, the upper mold 5 continues to move and can drive the punching head 54 to move downward to punch the formed template 100. When the upper mold 5 continues to move downward, the guide tube 72 will be contacted by the closing plate 71 and no longer move. At this time, the upper mold 5 continues to move, the elastic member 73 is stretched, and the upper mold The liquid in the upper mold liquid storage chamber 51 inside the tool 5 will be squeezed by the material guide pipe 72, so that the coolant enters the upper cooling chamber 53 through the liquid circulation channel 74 and the upper liquid outlet pipe 75, thereby cooling the upper forming plate 52. In the process of the upper mold 5 moving downward, it will also contact the annular piston block 82 and squeeze the annular piston block 82 to move downward. When the annular piston block 82 moves downward, it drives the connecting frame 83 to move downward, and the elastic member 84 is stretched. When the annular piston block 82 moves downward, it can squeeze the coolant in the lower mold liquid storage chamber 63 and inject the coolant into the lower cooling chamber 62 through the lower liquid outlet pipe 81, thereby cooling the lower forming plate 61. In this way, the present device can be used to extrude aluminum alloy parts, and the extruded upper forming plate 52 and lower forming plate 61 can be cooled to avoid overheating of the upper forming plate 52 and lower forming plate 61.

[0034] like Figure 7 and Figure 8 As shown, a feeding mechanism is also included, which includes a driving rack 91, a feeding track 92, an adjusting screw 96, a sliding frame 93, a conveying wheel 94 and a driving gear 95. Two driving racks 91 are connected to the right side of the mobile platform 4, and a feeding track 92 is connected to the right side of the top of the base 1. The sample 100 can be placed on the feeding track 92, and the movement of the sample 100 is guided by the feeding track 92. The left side of the feeding track 92 is slidably connected to the sliding frame 93, and the sliding frame 93 can move along the feeding track. The track 92 slides up and down, and the lower left side of the feeding track 92 is rotatably connected to an adjusting screw 96, and the adjusting screw 96 is threadedly matched with the sliding frame 93 so that the rotation of the adjusting screw 96 can drive the sliding frame 93 to move up and down through the thread. The upper part of the sliding frame 93 is rotatably connected to a conveying wheel 94, and the front and rear sides of the conveying wheel 94 are connected to a driving gear 95 through a one-way clutch. The driving gear 95 is located at the moving track of the driving rack 91, and the driving rack 91 can engage with the driving gear 95 when moving.

[0035] When placing the sample 100, the sample 100 can be placed on the feeding track 92, and the sample 100 can be transported by the feeding track 92 to ensure the stability of the sample 100 during transportation. When the mobile platform 4 moves downward, it can drive the driving rack 91 to move downward, and the driving rack 91 can mesh with the driving gear 95 when it moves downward, thereby poking the driving gear 95 to rotate. At this time, the conveying wheel 94 will not rotate under the action of the one-way clutch, and when the driving rack 91 moves upward, it can poke the driving gear 95 to rotate in the opposite direction, and the driving gear When the wheel 95 rotates in the reverse direction, it can drive the conveying wheel 94 to rotate in the reverse direction. At this time, a part has just been extruded and the formed part can be taken out manually. When the conveying wheel 94 rotates in the reverse direction, it can convey the template 100 and convey the template 100 to between the upper mold 5 and the lower mold 6. In this way, the conveying of the template 100 can be automatically realized, which is more convenient to operate. In actual operation, according to the thickness of the template 100, the adjusting screw 96 can be rotated to drive the sliding frame 93 to move up and down through the thread to adjust the height of the conveying wheel 94.

[0036] like Figure 9 and Figure 10 As shown, it also includes a clamping mechanism, which includes a slide rod 101, a pressure plate 102 and an elastic member 103. The bottom of the upper mold 5 is evenly and slidably connected to multiple slide rods 101, and a pressure plate 102 is fixedly connected between the bottoms of the multiple slide rods 101. The pressure plate 102 moves downward to press the template 100. An elastic member 103 is connected between the pressure plate 102 and the bottom of the upper mold 5, and the elastic member 103 is a clamping spring.

[0037] When the upper mold 5 moves downward, it can drive the pressure plate 102 and the slide bar 101 to move downward. After the pressure plate 102 moves downward, it can press the template 100, thereby fixing the template 100. The pressure plate 102 no longer moves after pressing the template 100. The upper mold 5 continues to move downward, and the elastic member 3 103 is compressed. By pressing the template 100 with the pressure plate 102, the template 100 can be helped to be fixed, making the template 100 more stable during the stamping process.

[0038] like Figure 11 As shown, a collecting frame 11 is also included. The collecting frame 11 is connected to the lower part of the base 1, and the discharge port 64 is located above the collecting frame 11. The waste discharged from the discharge port 64 will fall into the collecting frame 11 and be collected by the collecting frame 11.
