Description

Technical Field

[0001] The present invention relates to the technical field of metal stamping, and particularly to a metal forming stamping die that can be quickly demolded. Background Art

[0002] Metal stamping is a forming process in which a press applies external force to metal plates, strips and other materials through the cooperation of a metal die and a guide post, causing plastic deformation or separation to obtain stamping parts with the required shape and size. At the same time, after stamping is completed, a demolding mechanism is also required to perform a certain degree of demolding treatment on the stamped material.

[0003] In the prior art, for low-melting-point metals or thin-walled parts, they can be ejected after being briefly cooled in the mold, and then the final cooling is completed by external accelerated heat dissipation (such as in a water bath). However, during the ejection process, heat cannot be dissipated in a timely manner, and the workpiece will contact the top plate, making it even more difficult to dissipate heat, thereby prolonging the subsequent water bath heat dissipation time and reducing the overall production efficiency.

Detailed implementation manners

[0035] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below with reference to specific drawings. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other.

[0036] Please refer to Figure 1 - Figure 10, an embodiment of the present invention provides a technical solution: a metal forming stamping die that can be quickly demolded, including a chassis 1, a lower die 3 is fixedly connected to the chassis 1, an upper die 4 is provided above the lower die 3, an air pump 5 is fixedly connected to the upper end of the upper die 4, and the air pump 5 is fixedly connected to the top of the chassis 1. A guiding column 2 is movably inserted into one end of the upper die 4, and the guiding column 2 is fixedly connected to the chassis 1. A bottom plate 16 is provided at the bottom side of the inner cavity of the lower die 3. The side of the bottom plate 16 abuts against the inner wall of the lower die 3. An air pump 6 is fixedly connected between the bottom end of the bottom plate 16 and the chassis 1. An air extraction pump 7 is provided on the chassis 1 below the lower die 3. It further includes:

[0037] A sliding frame 9, which is used to connect the inner cavity of the lower die 3 with the outside when ejecting the workpiece. The sliding frame 9 is horizontally slidably arranged in the lower die 3. An air pump 8 is connected between one end of the sliding frame 9 extending to the lower side of the lower die 3 and the chassis 1;

[0038] A guiding groove 13, which is used for auxiliary heat dissipation through gas. The guiding groove 13 is opened in the bottom plate 16, and two ends of the guiding groove 13 are respectively communicated with an air inlet 15 and an air outlet 14. The air outlet 14 and the air inlet 15 are respectively communicated with the air extraction pump 7 and the outside;

[0039] A conversion mechanism 10, which is used to convert the heat dissipation part. The conversion mechanism 10 is arranged in the bottom plate 16;

[0040] An alternating mechanism 11, which is used to create a gap between the workpiece and the bottom plate 16. The alternating mechanism 11 is arranged in the bottom plate 16;

[0041] And an anti-blocking mechanism 17, which is used to prevent blockage when the alternating mechanism 11 operates. The anti-blocking mechanism 17 is arranged in the bottom plate 16.

[0042] Specifically, when the sliding rod 101 is far away from the air inlet 15, the air extraction pump 7 can extract air to assist in heat dissipation inside the bottom plate 16, accelerating the cooling time before the upper die 4 moves upward. When the sliding rod 101 is close to the air inlet 15, the gas extracted by the air extraction pump 7 can be completely used to dissipate heat in the area near the workpiece, improving the heat dissipation effect. The workpiece can dissipate heat while moving upward, reducing the subsequent heat dissipation time such as water bath. Moreover, two top frames 111 and two top frames 112 take turns to jack up the workpiece, enabling the whole workpiece to dissipate heat faster and more evenly, preventing quality problems such as cracks. The air extraction of the air extraction pump 7 can make the gas near the workpiece enter from the top end of the connecting pipe 171, and then the residues generated during demolding can be sucked in. When the sliding rod 101 moves, it can intermittently spray and flush the connecting pipe 171, effectively preventing the connecting pipe 171 from being blocked when sucking residues, further improving the effect of the air extraction pump 7 sucking and cleaning residues. When the sliding rod 101 moves, it can drive the baffle 175 to move up and down, disconnecting the guiding groove 13 from the connecting pipe 171 during reverse spraying and ensuring the spraying and flushing effect.

[0043] In another embodiment provided by the present invention, the conversion mechanism 10 includes a sliding rod 101, which is horizontally slidably arranged in the bottom plate 16. A placement groove 12 is formed in the inner wall of the bottom end of the lower mold 3. A roller 102 is arranged in the placement groove 12. The central axis of the roller 102 is movably arranged in the bottom plate 16, and the central axis of the roller 102 can horizontally move in the bottom plate 16. A dial rod 106 is arranged in the middle of the roller 102. One end of the sliding rod 101 close to the roller 102 is fixedly connected with an adapter rod 105. An extension rod 103 is fixedly connected to the sliding rod 101, and a shielding plate 104 is fixedly connected to the extension rod 103. The extension rod 103 extends into the air outlet 14 and is horizontally slidably arranged in the air outlet 14. The shielding plate 104 can shield the sliding groove where the extension rod 103 is located.

[0044] A plurality of dial rods 106 are arranged at equal intervals in a ring shape.

[0045] Specifically, when the sliding rod 101 is far from the air inlet 15, the air pump 7 can pump air to assist in cooling the inside of the bottom plate 16, accelerating the cooling time before the upper mold 4 moves upward. When the sliding rod 101 is close to the air inlet 15, the gas extracted by the air pump 7 can be completely used to cool the area near the workpiece, improving the cooling effect. The workpiece can be cooled while moving upward, reducing the subsequent cooling time such as water bath cooling.

[0046] In another embodiment provided by the present invention, the alternating mechanism 11 includes a top frame one 111 and a top frame two 112 that are slidably arranged up and down in the bottom plate 16. The upper surfaces of the top frame one 111 and the top frame two 112 are flush with the upper surface of the bottom plate 16. A first dial block 113 and a second dial block 115 are fixedly connected to the upper end of the sliding rod 101. An empty groove 114 is formed at the bottom end of the top frame two 112, and the second dial block 115 is arranged in the empty groove 114.

[0047] There are two top frame ones 111 and two top frame twos 112. The two top frame twos 112 are located between the two top frame ones 111, and the top frame one 111 and the top frame two 112 are arranged at equal intervals.

[0048] When the roller 102 is located in the placement groove 12, the second dial block 115 is located in the empty groove 114, and the first dial block 113 is far from the top frame one 111.

[0049] Specifically, the two top frame ones 111 and the two top frame twos 112 take turns to lift the workpiece upward, enabling the workpiece to dissipate heat faster and more evenly as a whole, preventing quality problems such as cracks. The air pumped by the air pump 7 can enter from the top end of the connecting pipe 171 for the gas near the workpiece, and thus the residues generated during demolding can be sucked in.

[0050] In another embodiment provided by the present invention, the anti-blocking mechanism 17 includes a connecting pipe 171 opened in the bottom plate 16, and the connecting pipe 171 is located at the bottom sides of the top frame one 111 and the top frame two 112. The bottom end of the connecting pipe 171 is communicated with the guide groove 13. A gas storage tank 172 is opened in the bottom plate 16 on one side of the connecting pipe 171. A lifting block 173 is slidably arranged up and down in the gas storage tank 172, and the lifting block 173 is fixedly connected to the top frame one 111 or the top frame two 112. The bottom end of the gas storage tank 172 is communicated with the connecting pipe 171. The upper end of the connecting pipe 171 is communicated with the outside of the bottom plate 16. The upper end of the sliding rod 101 abuts against an inserting frame 174, and the inserting frame 174 is horizontally slidably arranged in the bottom plate 16. There is one inserting frame 174, and the inserting frame 174 is arranged close to the top frame one 111. A baffle 175 is obliquely slidably arranged at the upper end of the inserting frame 174, and the baffle 175 is located in the connecting pipe 171. A baffle 175 is arranged under each of the top frame one 111 and the top frame two 112, and a connecting frame 177 is fixedly connected between the baffles 175. The baffle 175 is vertically movably inserted into the bottom plate 16, and a straight slot 176 is opened on the baffle 175.

[0051] The inserting frame 174 is made of a material with a large coefficient of friction. The straight slot 176 close to the top frame one 111 is opened on the lower side of the baffle 175, and the straight slot 176 close to the top frame two 112 is opened on the upper side of the baffle 175.

[0052] Specifically, when the sliding rod 101 moves, it can intermittently spray and flush the connecting pipe 171, which can effectively prevent the connecting pipe 171 from being blocked when absorbing residues, and further improve the effect of the air pump 7 in pumping air and cleaning residues. When the sliding rod 101 moves, it can drive the baffle 175 to move up and down, so that when reverse spraying and flushing, the guide groove 13 is disconnected from the connecting pipe 171, ensuring the spraying and flushing effect.

[0053] Working principle: When using this device, first press down the upper mold 4 to press the workpiece into shape. After forming, it needs to be cooled for a period of time, and then the upper mold 4 is lifted. Therefore, when cooling, start the air pump 7. The air on the outer wall enters through the air inlet 15, passes through the guide groove 13, and is discharged from the air outlet 14 to the air pump 7. In this way, the air pumping of the air pump 7 can accelerate the cooling of the workpiece. It should be noted that when cooling, the water cooling method can be adopted, and air cooling can be added to improve the cooling speed;

[0054] After cooling for a period of time, lift the upper mold 4 and start the air pump three 8 to move the sliding frame 9 away from the bottom plate 16. At this time, the inner cavity of the lower mold 3 is communicated with the lower side of the lower mold 3. Then start the air pump two 6 to lift the bottom plate 16 upward. When the bottom plate 16 moves upward, the roller 102 will be squeezed by the inner wall of the placement groove 12. Therefore, both the roller 102 and the sliding rod 101 move toward the air inlet 15. Then the sliding rod 101 blocks the air inlet 15, and the gas no longer enters the guide groove 13 from the air inlet 15, and all the gas is pumped into through the connecting pipe 171;

[0055] When the roller 102 is squeezed by the placement groove 12 and the slide bar 101 moves towards the air inlet 15, the second shifting block 115 will move out of the empty groove 114. After that, when the bottom plate 16 moves upward, the outer wall of the roller 102 abuts against the inner wall of the lower mold 3, and the roller 102 will rotate. The rotation of the lever 106 will drive the connecting rod 105 to move towards the air inlet 15, and the slide bar 101 will drive the first shifting block 113 to jack up the first top frame 111. When the lever 106 no longer drives the connecting rod 105, the airflow in the air outlet 14 will scrape the extension rod 103 towards the roller 102, so that the slide bar 101 drives the second shifting block 115 to jack up the second top frame 112. When the first top frame 111 moves upward, the slide bar 101 drives the plug frame 174 towards the first top frame 111 through friction, and the baffle 175 moves upward. The straight slot 176 is located in the connecting pipe 171, so that the top end of the gas connecting pipe 171 enters the guide groove 13, and heat dissipation is carried out at the gap between the workpiece and the bottom plate 16. Vice versa, when the second top frame 112 moves upward, the plug frame 174 drives the baffle 175 close to the first top frame 111 to move downward, and then the baffle 175 close to the second top frame 112 moves downward. Since the straight slot 176 close to the second top frame 112 is arranged on the upper side of the baffle 175, when the baffle 175 moves downward, the straight slot 176 is located in the connecting pipe 171, and air can be sucked for heat dissipation. The heat dissipation area is converted from the inside of the bottom plate 16 to a region closer to the workpiece. The two first top frames 111 and the two second top frames 112 take turns to jack up the workpiece, so that the positions where the first top frame 111 and the second top frame 112 contact the workpiece can also be quickly cooled, so that the whole workpiece can be cooled faster and more evenly, preventing quality problems such as cracks. The two second top frames 112 are arranged in the middle, so that when the workpiece is jacked up, the force on the workpiece is more stable;

[0056] And the air extraction of the air extraction pump 7 can make the gas near the workpiece enter from the top end of the connecting pipe 171, and then the residues generated during demoulding can be sucked in, which can play a role in cleaning while dissipating heat;

[0057] When the first top frame 111 moves upward, the lifting block 173 will also move upward accordingly. Air will enter the lower region of the air storage tank 172 from the connecting pipe 171. When the first shifting block 113 and the first top frame 111 are separated, the first top frame 111 will drop due to gravity, driving the lifting block 173 to squeeze downward. And at this time, the baffle 175 close to the first top frame 111 moves downward, and the connecting pipe 171 and the guide groove 13 are no longer connected. The lifting block 173 will flush the gas in the lower part of the air storage tank 172 into the connecting pipe 171, so that the top end of the connecting pipe 171 and the connection between the connecting pipe 171 and the air storage tank 172 can be reversely flushed. Intermittently flushing the connecting pipe 171 can effectively prevent the connecting pipe 171 from being blocked when absorbing residues, and further improve the effect of the air extraction pump 7 in extracting air and cleaning residues.
