Description

Technical Field

[0001] This invention relates to the field of molding devices for metal powder forming, and more specifically to an automated die-casting device for metal powder cores. Background Technology

[0002] Metal soft magnetic powder core (referred to as "metal powder core") is a soft magnetic material. It is a magnetic core produced by special process using powder made of metal or alloy soft magnetic materials. Metal powder core is mainly used in new energy vehicles, high-tech communications and consumer electronics.

[0003] Metal powder cores are made by mixing and pressing powders of metal or alloy soft magnetic materials with insulating additives. The manufacturing process of metal powder cores is relatively complex. After preparing the raw materials, the raw materials are made into metal powders, an insulating layer is coated on the surface of the metal powders, and then the loose metal powders are pressed into preforms before annealing and surface treatment.

[0004] Existing molding equipment typically has a detachable mold consisting of an upper and lower mold. However, because metal powder has high hardness, the mold is easily worn and needs frequent replacement. Replacement requires stopping the machine, which is cumbersome and increases time costs. In addition, feeding and mold switching still require manual operation, resulting in low automation.

[0005] Therefore, existing molding equipment suffers from problems such as inconvenient mold replacement and low degree of automation. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an automated die casting device for metal powder cores that is more convenient to change molds and has a higher degree of automation.

[0007] To solve the above-mentioned technical problems, the present invention provides an automated die casting device for metal powder cores, comprising a conveying component for conveying the lower mold from front to back, and a lower mold loading component for sequentially placing the lower mold at the loading end of the conveying component, a feeding tank for feeding metal powder into the lower mold, a compaction component for pre-compacting the metal powder in the lower mold containing metal powder, and an upper mold loading component for pressing the upper mold into the lower mold containing metal powder.

[0008] As a further improvement of the present invention: the conveying component includes a smooth base plate for sliding a plurality of parallel lower dies from front to back, and baffles respectively vertically installed on the left and right sides of the smooth base plate. At least one first telescopic member is fixedly installed next to the loading end of the smooth base plate for pushing the lower dies at the loading end of the smooth base plate from front to back.

[0009] Preferably, the lower mold loading component is a square ring-shaped first limiting frame fixedly installed on the top of the two baffles for stacking multiple lower molds, and the first limiting frame is located above the loading end of the smooth base plate.

[0010] As a further improvement of the present invention: the feeding tank includes an inner column and an outer tank body. A cavity for placing metal powder is formed between the inner wall of the outer tank body and the outer surface of the inner column. A feeding port is opened at the top of the outer tank body, and a feeding funnel is fixedly installed at the feeding port. A discharge port is opened at the bottom of the outer tank body, and a discharge short pipe is fixedly installed at the discharge port. A material valve is provided in the discharge short pipe. A discharge head for allowing the metal powder in the cavity to fall into the lower mold is provided at the bottom of the outer tank body.

[0011] As a further improvement of the present invention: the compaction component includes a lifting plate that can be raised and lowered and at least one vertical third telescopic component for driving the lifting plate to rise and fall. The bottom of the lifting plate is provided with pressure plates whose number and position correspond to the concave mold at the top of the lower mold. The bottom of the pressure plate is provided with compaction blocks whose shape matches the concave mold. At least two second return springs are vertically fixed between each pressure plate and the lifting plate.

[0012] Preferably, each pressure plate is provided with a lifting hammer for impacting the pressure plate and a vertical fourth telescopic member for driving the hammer to rise and fall.

[0013] As a further improvement of the present invention: the upper mold includes a main body for pressing in conjunction with the lower mold. The left and right sides of the main body are equipped with a sliding plate that can slide in the left and right direction. The left and right sides of the sliding plate are respectively provided with sliding cavities for sliding. The sliding plate is connected to the inner wall of the sliding cavity by at least one first return spring. The upper mold feeding component includes a square ring-shaped second limiting frame for stacking multiple upper molds. The second limiting frame is fixedly installed on the top of two baffles. The left and right sides of the second limiting frame are provided with temporary placement grooves for the sliding plate of the bottom upper mold in the second limiting frame to extend into. The top of the second limiting frame is fixedly installed with a vertical second telescopic member for pushing the upper mold in the second limiting frame downward.

[0014] As a further improvement of the present invention: the unloading end of the conveyor is provided with a mold opening member for opening the upper mold and the lower mold at the unloading end.

[0015] The beneficial effects of this invention are as follows: The automated die-casting device for metal powder cores provided by this invention offers convenient mold replacement and a high degree of automation. The conveying component of the device can transport the lower mold from front to back. Metal powder is placed into the lower mold using a feeding tank, and the metal powder in the lower mold is pre-compacted by a compaction component. Then, the upper mold feeding component presses the upper mold into the lower mold containing the metal powder to complete the molding process. If a mold is damaged, it can be directly removed and no longer used in the production line. Replacement is very convenient and quick, without the need for machine downtime, saving time and costs. Secondly, the feeding of the lower mold, the feeding of the upper mold, and the molding are all completed automatically without manual operation, thus achieving a high degree of automation and high efficiency.

[0047] like Figure 7 , Figure 8 , Figure 9 , Figure 15 , Figure 16 As shown, the compaction component 5 includes a lifting plate 501 capable of being raised and lowered, and at least one vertical third telescopic component 502 for driving the horizontally positioned lifting plate 501 to rise and fall.

[0048] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 15 As shown, the upper mold 102 includes a main body 1021 for pressing in conjunction with the lower mold 101. Both sides of the main body 1021 are equipped with sliding plates 1022 that can slide in the left-right direction. The cross-section of the sliding plates 1022 is L-shaped. Sliding cavities for sliding are respectively opened on the left and right sides of the sliding plates 1022. The sliding plates 1022 are connected to the inner walls of the sliding cavities by at least one first return spring 1023. When the distance between the sliding plates 1022 is at its maximum, the first return spring 1023 is in a naturally extended state. The upper mold loading component 6... The system includes a square-ring-shaped second limiting frame 601 for stacking multiple upper molds 102. The second limiting frame 601 is fixedly installed on the top of two baffles 202. Temporary slots 6011 for the card plate 1022 to extend into are provided on the left and right walls of the second limiting frame 601 on the side that contacts the card plate 1022 of the bottom upper mold 102. A vertical second telescopic member 602 for pushing the upper molds 102 downwards is fixedly installed on the top of the second limiting frame 601. The left and right walls of the lower mold 101, on the side that contacts the card plate 1022, both have slots 1011 for engaging with the card plate 1022.

[0049] like Figure 7 , Figure 8 , Figure 9 , Figure 17 , Figure 18 As shown, the unloading end of the conveyor 2 is provided with a mold opening component 8 for opening the upper mold 102 and the lower mold 101 at the unloading end. The mold opening component 8 includes an inverted U-shaped frame 801 fixedly installed on the top of the baffle 202. A plate push rod 802 for pushing the plate 1022 located in the slot 1011 of the lower mold 101 to the center of the upper mold 102 and a main body push rod 803 for pushing the main body 1021 in the lower mold 101 upwards are fixedly installed on the front side of the vertical end of the inverted U-shaped frame 801 near the unloading end of the conveyor 2. The front end faces of the plate push rod 802 and the main body push rod 803 are both inclined.

[0050] The working principle of this invention is as follows: The upper mold 102 is placed in the second limiting frame 601. After the upper mold 102 enters the second limiting frame 601, the two clamping plates 1022 are squeezed by the left and right side walls of the second limiting frame 601. Therefore, the first return spring 1023 is in a compressed state, and the upper mold 102 falls freely. When the two clamping plates 1022 reach the bottom of the second limiting frame 601, due to the presence of the temporary placement groove 6011, the clamping plates 1022 are no longer squeezed by the left and right side walls of the second limiting frame 601. The first return spring 1023 returns to the initial natural extension state, and the upper mold 102 stays at this position and no longer falls. The upper mold 102 continues to be stacked and placed. The first return spring 1023 of the upper mold 102 on the bottom layer is in a compressed state. Multiple lower molds 101 are stacked in the frame. The lowest lower mold 101 is located on the loading end of the smooth base plate 201. The side of the lower mold 101 that is in contact with the upper mold 102 faces upward. When the lower mold 101 needs to move backward, the first telescopic member 203 is activated, the telescopic end extends, and pushes the lower mold 101 at the loading end of the smooth base plate 201 to move backward. When the telescopic end shortens, after losing the support of the original lower mold 101 at this position and the obstruction of the telescopic end, the lower mold 101 above the original lower mold 101 at the loading end of the smooth base plate 201 will naturally fall to the loading end of the smooth base plate 201 under the action of gravity.

[0051] Metal powder is poured into the cavity through the feed funnel. The first motor 701 is started, and the output shaft of the first motor 701 drives the first gear 702 to rotate. The first gear 702 drives the second gear 703 to rotate through the synchronous belt 704, thereby driving the outer tank 402 to rotate. When the outer tank 402 rotates, it drives multiple stirring rods 706 to rotate. The ends of the multiple stirring rods 706 away from the outer tank 402 slide in the annular groove 4011 on the surface of the inner column 401. At the same time, the outer tank 402 drives the gear ring 705 to rotate, and the gear ring 705 drives each third gear 707 to rotate in the horizontal direction. Each third gear 707 drives the first-stage stirring component to rotate through the belt, so that each stirring rod 706 rotates in the vertical direction as a whole while also rotating in the horizontal direction, thus fully stirring the material in the cavity.

[0052] After mixing is complete, once the lower mold 101 reaches below the discharge head 403, the valve opens, and the metal powder falls into the lower mold 101. Once the expected amount is reached, the valve closes. As the first telescopic component 203 pushes the lower mold 101 at the loading end of the smooth base plate 201, the other lower molds 101 on the smooth base plate 201 will continue to slide backward. The bottom of the scraper 404 contacts the bottom of the lower mold 101, scraping off excess metal powder from its top as the lower mold 101 moves backward.

[0053] When the lower mold 101, carrying the compacted metal powder, reaches directly below the upper mold 102, the telescopic end of the second telescopic member 602 extends, causing all the upper molds 102 in the second limiting frame 601 to move downwards. Under the downward force, the bottom upper mold 102's clamping plate 1022 is pressed by the lower edge of the temporary placement groove 6011, and the first return spring 1023 is gradually compressed. The bottom upper mold 102 continues to fall into the lower mold 101 until the clamping plate 1022 reaches the clamping groove 1011 of the lower mold 101. At this point, the first return spring 1023 returns to its natural extended state, and the clamping plate 1022 is engaged in the clamping groove 1011. Meanwhile, the upper mold 102 that was previously above the bottom upper mold 102 reaches the bottom, and the two clamping plates 1022 enter the temporary placement groove 6011 respectively.

[0054] The metal powder in the upper mold 102 and the lower mold 101 is pressed into shape. The lower mold 101 drives the upper mold 102 to continue to move backward on the smooth base plate 201. The length of the clamping plate push rod 802 is longer than the length of the main body push rod 803. Therefore, the clamping plate push rod 802 will first extend into the clamping groove 1011 and press the clamping plate 1022 to the center of the upper mold 102. Then the main body push rod 803 will be inserted into the gap between the main body 1021 and the lower mold 101 and push the main body 1021 upward to open the mold. At this time, the preform and the mold can be taken out.

[0055] It should be noted that the present invention is not limited to the specific structure shown in the accompanying drawings in the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art.
