[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In the present invention, the workpieces to be processed are stacked on the feeding mechanism, and the feeding mechanism sends them to the workbench one by one for processing. After the feeding mechanism places the workpiece in the molding groove of the protruding block, the lifting seat is lowered by the first hydraulic cylinder, and the workpiece is die-cast by the extrusion of the pressing block. During die-casting, the waste of the workpiece will extend from the edge of the workpiece. At this time, the first resistance block is lowered by the ejection mechanism. Because the third inclined surface of the first ejection block is in conflict with and fits with the second inclined surface of the first resisting block, the first resisting block will resist the first ejection block when it descends, so that the first inclined surface of the first ejection block cuts the waste on the edge of the workpiece and separates it from the workpiece, and then the processed workpiece is taken by the material taking mechanism, and then the material taking mechanism, the ejection mechanism and the first hydraulic cylinder are reset in sequence, and the above operation cycle can be repeated. The cut waste will fall to the outside of the protruding block, which will not affect the processing process and facilitate centralized processing after the processing is completed. Therefore, the present invention can remove the waste material on the edge of the workpiece after die-casting, and separate and take out the workpiece from the waste material, and has the advantage of high safety.

[0015] 2. In the present invention, when the workpiece is formed by die-casting, the material-taking mechanism is located at the top of the convex block at the top of the convex groove. At this time, the second hydraulic cylinder is in an extended state and presses against the second resistance block so that its upper end surface is in resistance with the top surface of the movable cavity. The inner side of the second ejection block leaks outward due to the second resistance block and extends into the transverse groove, thereby improving the stability of the convex block during the die-casting process. When the die-casting is completed and the material is to be taken, the second hydraulic cylinder contracts first to move the second resistance block downward. Under the action of the first spring, the fourth inclined surface of the second ejection block moves inward along the fifth inclined surface of the second resistance block until it is no longer in contact with the transverse groove. The continued contraction of the second hydraulic cylinder causes the convex block to descend until it lands at the bottom of the convex groove. At this time, the third guide rod under the ejection plate contacts the ground of the convex groove so that the ejection plate ejects the workpiece upward. The third hydraulic cylinder extends and pushes the workpiece to the discharge channel through the push plate to complete the material taking.

[0016] 3. In the present invention, the ejection mechanism controls the rotation of the rotating shaft through the first motor, and the cam on the rotating shaft rotates accordingly. When the protruding part of the cam contacts the push rod, it will resist the push rod and move it downward, so that the first resistance block contacts the first ejection block downward and moves; when the protruding part of the cam does not contact the push rod, the ejection rod is reset by the elastic force of the second spring.

DETAILED DESCRIPTION

[0026] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0027] Embodiment: Fully automatic integrated die-casting equipment for heat dissipation substrate, comprising: Figure 1-8As shown, it includes a workbench 1, on which a plurality of first guide rods 2 are arranged, and between the upper ends of the first guide rods 2, a mounting beam 3 is fixedly connected, and a first hydraulic cylinder 4 is arranged on the mounting beam 3; the lower end of the first hydraulic cylinder 4 is connected to a lifting seat 5, and the lifting seat 5 is slidably connected to the first guide rods 2; Figure 2 As shown, a pressing block 6 is provided at the lower end of the lifting seat 5; a protruding block 7 is provided on the workbench 1.

An ejector plate 20 is placed in the molding groove 10, and a plurality of third guide rods 21 are arranged below the ejector plate 20. The third guide rods 21 pass through the convex block 9 and leak out from below the convex block 9. When the convex block 9 descends with the material taking mechanism 11 and contacts the bottom surface of the convex groove 8, the third guide rods 21 push up the ejector plate 20 due to the contact with the bottom surface of the convex groove 8, thereby helping to take the workpiece out of the molding groove 10. The workpieces to be processed are stacked on the feeding mechanism 19, and are sent to the workbench 1 one by one by the feeding mechanism 19 for processing. After the feeding mechanism 19 places the workpiece in the molding groove 10 of the protruding block 7, the lifting seat 5 is lowered by the first hydraulic cylinder 4, and the workpiece is die-cast by the extrusion of the pressing block 6. During die-casting, the waste of the workpiece will extend from the edge of the workpiece. At this time, the first resistance block 16 is lowered by the ejection mechanism 15. Because the third inclined surface 18 of the first ejection block 13 is in conflict with and fits with the second inclined surface 17 of the first resistance block 16, the first resistance block 16 will resist the first ejection block 13 and move outward when it descends, so that the first inclined surface 14 of the first ejection block 13 cuts the waste on the edge of the workpiece and separates it from the workpiece, and then the processed workpiece is taken out by the picking mechanism 11. After that, the picking mechanism 11, the ejection mechanism 15 and the first hydraulic cylinder 4 are reset in turn, and the above operation cycle can be repeated. The cut waste will fall to the outside of the protruding block 7, which will not affect the processing process and will facilitate centralized processing after the processing is completed.

When the workpiece is formed and die-casted, the convex block 9 is located at the top of the convex groove 8. At this time, the second hydraulic cylinder 104 is in an extended state and presses against the second resistance block 105 so that its upper end surface contacts the top surface of the active cavity. The inner side of the second ejection block 101 leaks outward due to the second resistance block 105 and extends into the transverse groove 103, thereby improving the stability of the convex block 9 during the die-casting process. When the die-casting is completed and the material is to be taken out, the second hydraulic cylinder 104 contracts first to move the second resistance block 105 downward, and the first spring 1 Under the action of 12, the fourth inclined surface 102 of the second ejection block 101 moves inward along the fifth inclined surface 106 of the second resistance block 105 until it is no longer in contact with the transverse groove 103. The continued contraction of the second hydraulic cylinder 104 causes the convex block 9 to drop until it falls to the bottom of the convex groove 8. At this time, the third guide rod 21 below the ejection plate 20 contacts the ground of the convex groove 8, causing the ejection plate 20 to eject the workpiece upward. The third hydraulic cylinder 108 extends and pushes the workpiece to the discharge channel 107 through the push plate 109 to complete the material removal. Furthermore, in order to prevent the second ejection block from being squeezed against the inner wall of the convex groove and unable to rise normally due to the resistance of the second resistance block to the second ejection block during the process of the convex block rising, rolling belts are respectively provided on both sides of the convex groove, and the rolling belts roll upward with the resistance of the second ejection block.Furthermore, in order to prevent the second push block 101 from being unable to rise normally due to the interference of the second resistance block 105 with the second push block 101 during the rising process of the convex block 9, rolling belts are respectively provided on both sides of the convex groove 8, and the rolling belts roll upward with the interference of the second push block 101.

When the protruding part of the cam 202 contacts the push rod 203, it will resist the push rod 203 and move it downward, so that the first resistance block 16 resists and moves downward with the first ejection block 13; when the protruding part of the cam 202 does not contact the push rod 203, the ejection rod is reset by the elastic force of the second spring 206.

[0031] Preferably, if Figure 1 and 2 As shown, the workbench 1 is provided with a plurality of fourth hydraulic cylinders 22, and the output ends of the fourth hydraulic cylinders 22 face upward and are fixedly connected to the lifting seat 5.

[0032] Preferably, if Figure 1 and 2 As shown, the outer ring 204 of the first guide rod 2 is wound with a third spring 23 located between the lifting seat 5 and the table surface of the workbench 1 , and the third spring 23 further assists the lifting of the lifting seat 5 .

[0033] Working principle:

[0034] Loading: First, the workpieces to be processed are neatly and linearly stacked on the loading platform 400 of the feeding mechanism 19. The feeding mechanism 19 starts to work, and the second motor 408 of its moving mechanism 402 controls the rotation of the first screw 409. Through the cooperation of the first screw 409 and the first nut block 410, the mounting frame 407 moves along the guide of the first screw 409, thereby driving the suction cup 404 to descend in the Z-axis direction until the suction cup 404 contacts the workpiece on the loading platform 400. Then, the external negative pressure device generates suction force on the suction cup 404 through the pipeline to firmly suck the workpiece, and the second motor 408 raises the workpiece. Next, the third motor 414 controls the rotation of the second screw 415. Through the cooperation of the second screw 415 and the second nut block 416, the moving bar 411 moves along the guide of the second screw 415, thereby controlling the suction cup 404 to move in the X-axis direction, and moving the sucked workpiece toward the molding groove 10 of the protruding block 7 on the workbench 1. When reaching above the molding groove 10, the second motor 408 causes the workpiece to fall into the molding groove 10, and at the same time the external negative pressure device stops working, the suction cup 404 loses suction, and the workpiece is accurately placed in the molding groove 10, completing the loading process.

[0035] Die casting: After the material is loaded, the first hydraulic cylinder 4 is activated to push the lifting seat 5 to slide downward along the first guide rod 2. As the lifting seat 5 descends, the pressing block 6 at its lower end gradually approaches and squeezes the workpiece in the molding groove 10. Under the strong pressure of the pressing block 6, the workpiece gradually deforms and is finally die-cast into the desired shape in the molding groove 10.

[0036] Waste separation: During the die-casting process, the waste of the workpiece will extend from the edge of the workpiece. At this time, the ejection mechanism 15 begins to work. The first motor 200 controls the rotation of the rotating shaft 201, and the cam 202 on the rotating shaft 201 rotates accordingly. When the protruding part of the cam 202 contacts the push rod 203, it will resist the push rod 203 to move downward, and the first resistance block 16 connected to the lower end of the push rod 203 will also move downward. Since the third inclined surface 18 of the first ejection block 13 and the second inclined surface 17 of the first resistance block 16 are in conflict and fit, the first resistance block 16 will resist the first ejection block 13 and move outward when it descends. After the first ejection block 13 moves outward, the first inclined surface 14 of its outer end surface will cut off the waste extending from the edge of the workpiece, so that the waste is separated from the workpiece. The cut waste will fall to the outside of the protruding block 7, which will not affect the subsequent processing process and is convenient for centralized processing after the processing is completed.

[0037] Material collection: After the die casting and waste separation are completed, the material collection stage is entered. The second hydraulic cylinder 104 begins to shrink, first causing the second contact block 105 to move downward. Since the inner end of the second push-out block 101 is provided with a fourth inclined surface 102, the second contact block 105 has a fifth inclined surface 106 on both sides, and the fifth inclined surface 106 conflicts with and fits with the fourth inclined surface 102, and at the same time, the second push-out block 101 is provided with side wing plates 110 on both sides, and the second guide rod 111 in the movable cavity is slidably connected with the side wing plates 110, and the first spring 112 around the outer ring 204 of the second guide rod 111 is always in a stretched state. Therefore, under the action of the first spring 112, the fourth inclined surface 102 of the second push-out block 101 will move inward along the fifth inclined surface 106 of the second contact block 105 until the second push-out block 101 is no longer in contact with the transverse groove 103. The second hydraulic cylinder 104 continues to shrink, causing the convex block 9 to descend until it falls to the bottom end of the convex groove 8. At this time, the third guide rod 21 below the ejector plate 20 contacts the bottom surface of the convex groove 8, and the third guide rod 21 pushes up the ejector plate 20 due to the contact with the bottom surface of the convex groove 8, and the ejector plate 20 pushes the processed workpiece upward. The third hydraulic cylinder 108 extends, and the push plate 109 at its extended end pushes the ejected workpiece to the discharge channel 107, and the workpiece moves out of the equipment along the discharge channel 107, completing the material removal process.

[0038] System reset and circulation: After the material is taken, the material taking mechanism 11, the ejection mechanism 15 and the first hydraulic cylinder 4 are reset in sequence, and the equipment returns to the initial state, and the above-mentioned operations of loading, die-casting and waste separation, and taking can be repeated to realize cyclic processing.
