Description

Technical Field

[0001] This invention relates to the field of aluminum alloy profile processing technology, and more specifically, to an aluminum alloy profile radiator and a radiator extrusion forming apparatus thereof. Background Technology

[0002] With the development of the three major industries of aviation, construction and automobiles, the production and application of aluminum alloys have also become more extensive. Aluminum alloys have low density but relatively high strength, approaching that of high-quality steel. In addition, they have good plasticity. Therefore, when processing aluminum alloys, extruders are usually used to extrude and shape them. A heated rod-shaped aluminum alloy is pushed into the mold by a cylinder. The ductility of the heated rod-shaped aluminum alloy increases, and it will pass through the mold due to extrusion, thus achieving the shaping of the rod-shaped aluminum alloy. Aluminum alloy heat sinks are one such product that is processed and formed using this method.

[0003] For example, the patent with authorization announcement number CN115090703B and announcement date of November 4, 2025 discloses an aluminum extrusion forming device and forming process. By setting up a mold changing component, the mold placed on the mold changing component can be quickly connected with the ingot holding cylinder in the discharge box. At the same time, multiple molds can be set up to reduce the time for mold installation and replacement. Meanwhile, the temperature control component in the discharge box can control the temperature of the mold in the discharge box and keep it at a certain temperature, thereby improving production efficiency and product quality.

[0004] However, during mold replacement, the mold needs to be moved inside the discharge box. Therefore, the width of the discharge box cavity must be greater than the width of the mold. If the mold enters the cavity and extrusion is performed, the gap between the mold and the discharge box cavity due to the width difference will allow aluminum alloy to enter. This not only wastes aluminum alloy material but also causes the aluminum alloy to block the gap between the mold and the discharge box cavity, increasing the friction between the mold and the inner wall of the discharge box cavity. This affects subsequent mold replacement. Furthermore, after the aluminum alloy adhering to the inner wall of the discharge box cavity cools, it will scrape one side of the mold when the mold moves by, scratching the injection port on the mold and affecting the accuracy of the extruded product during subsequent extrusion. Summary of the Invention

[0005] This invention provides an aluminum alloy profile radiator and its radiator extrusion molding device, solving the technical problem in related technologies that aluminum material will block the gap between the mold and the discharge box chamber.

[0006] The present invention provides an aluminum alloy profile heat sink, including a fixed base plate, a plurality of heat sinks are fixedly connected at equal intervals on the top of the fixed base plate, and a plurality of fixing holes are equally spaced on both sides of the top of the heat sink base plate.

[0007] An aluminum alloy profile heat sink extrusion forming device includes a first pushing mechanism, a conveying mechanism, a discharge box, and a conveying mechanism. The first pushing mechanism, the conveying mechanism, the discharge box, and the conveying mechanism are arranged sequentially along the material conveying direction. A driving mechanism is provided below the discharge box and is connected to a support platform. The driving mechanism is used to drive the support platform to move along the length direction of the discharge box. A mold is slidably connected to the top of the support platform. A second pushing mechanism is fixedly installed on the side of the discharge box away from the conveying mechanism. A pushing ring is provided inside the discharge box. The output shaft of the second pushing mechanism is connected to the pushing ring. The second pushing mechanism is used to drive the pushing ring to move along the width direction of the discharge box.

[0008] In a preferred embodiment, the discharge box has a cavity extending along its length. The drive mechanism passes through the cavity of the discharge box. A first spiral plate is slidably connected to the side of the discharge box away from the conveying mechanism. The end of the first spiral plate near the conveying mechanism is connected to the side of the push ring. The movable end of the second push mechanism is connected to the first spiral plate. A feed pipe is fixedly connected to the side of the discharge box near the conveying mechanism, and a discharge pipe is fixedly connected to the side of the discharge box away from the conveying mechanism. The output shaft of the first push mechanism, the discharge pipe, the feed pipe, and the central axis of the push ring are all on the same horizontal plane.

[0009] In a preferred embodiment, the support platform is U-shaped, and a second slot is provided at the top center of the support platform near the conveying mechanism. The second slot is opened along the width direction of the discharge box. A limit block is fixedly connected to the bottom of the mold near the conveying mechanism, and the limit block is slidably connected inside the second slot.

[0010] In a preferred embodiment, the discharge box includes a second rotary plate located above the push ring and fixedly connected to the push ring. A flip plate is rotatably connected to the bottom end of the second rotary plate near the conveying mechanism. An abutment baffle is provided on the side of the flip plate away from the second rotary plate. The abutment baffle is connected to the bottom end of the second rotary plate, and the abutment baffle and the flip plate form an abutment limit. A reset block is provided above the mold near the second rotary plate and is connected to the mold. The second rotary plate is L-shaped, the length of the flip plate is greater than that of the abutment baffle, and the bottom end of the flip plate and the top end of the reset block are both arc-shaped.

[0011] In a preferred embodiment, the support platform includes a first motor, which is fixedly installed on the side of the support platform near the discharge pipe. A first gear and a second gear are rotatably connected to the lower part of the support platform. The output end of the first motor is connected to the first gear, and the first gear meshes with the second gear. A first tilting seat is fixedly connected to the shaft of the first gear, and a second tilting seat is fixedly connected to the shaft of the second gear. Tilting limit blocks are fixedly connected to both sides of the support platform along its length. A first slot is provided on the inner wall of the discharge box chamber near the conveying mechanism, and the limit block is slidably connected to the first slot.

[0012] In a preferred embodiment, the flipping limiting block is located below the first flipping seat and the second flipping seat, and there are two sets of flipping limiting blocks, which respectively form abutment limiting with the first flipping seat and the second flipping seat.

[0013] In a preferred embodiment, the tops of both the first and second flip seats after flipping are located below the top of the support platform, and the first and second slots have the same shape and depth.

[0014] In a preferred embodiment, the discharge box further includes a vertical chute and a receiving chute. The receiving chute is formed on the inner wall of the discharge box, and the vertical chute is formed inside the discharge box. The vertical chute and the receiving chute are interconnected. A vertical locking rod is slidably connected inside the vertical chute, and a wedge-shaped slide is slidably connected inside the receiving chute. The vertical locking rod and the wedge-shaped slide form a wedge fit. A spring is installed inside the receiving chute. One end of the spring is connected to the wedge-shaped slide, and the other end of the spring is connected to the inner wall of the receiving chute. An abutment block is fixedly connected to the middle of the side of the support platform near the wedge-shaped slide. The abutment block and the wedge-shaped slide form a wedge fit. A first loop plate is located below the push ring and is fixedly connected to the push ring. A rectangular opening is opened at the bottom of the first loop plate. The vertical locking rod and the opening on the first loop plate form an abutment limit.

[0015] In a preferred embodiment, the first circular plate is L-shaped, the end of the contact block near the receiving groove and the bottom end of the vertical lever are both arc-shaped, the wedge-shaped slide is divided into a long block at the bottom and a short block at the top, the long and short blocks are connected to each other, and the short block is located on the side of the top of the long block away from the support platform, and the height transition ends of the short block and the long block are sloped.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. The present invention is equipped with a second pushing mechanism, a first forming plate and a pushing ring. The cylinder drives the mold to achieve a tight fit with the inner wall of the discharge box, effectively eliminating the risk of aluminum chips remaining in the gap, avoiding scratches on the mold by aluminum chips, ensuring the stability and consistency of each extrusion operation, reducing the problem of finished product accuracy deviation caused by mold damage, and making the entire extrusion process smoother and more efficient.

[0018] 2. The present invention is provided with a second loop plate, a flip plate and an abutment baffle. The second loop plate abuts against the reset block to limit the movement, thereby driving the mold to accurately retract into the support table slot, so that a safe gap is created between the mold and the inner wall of the cavity, avoiding friction between the mold and the inner wall when the support table moves. After the support table drives the mold away, the second pushing mechanism resets again to make the pushing ring fit against the inner wall of the cavity, preventing the reset block and the flip plate from abutting against each other when a new mold is replaced, thus ensuring the smoothness of the mold changing process.

[0019] 3. The present invention is provided with a support platform, a first motor, a first flipping seat and a second flipping seat. Through the sliding cooperation of the limiting block and the slot and the synergistic effect of the motor driving the gear set to drive the flipping seat to unfold, the unfolding of the flipping seat completely disengages the support platform from the mold. Even if the support platform moves due to accidental start-up, it cannot interfere with the mold, avoid friction damage between the mold and the inner wall of the cavity, reduce product scrap due to mold displacement or damage, and reduce equipment failure rate.

[0020] 4. This invention is equipped with a wedge-shaped slide, a first circular plate, a vertical locking rod, and a stop block. When the support platform is not reset, the vertical locking rod effectively stops and limits the first circular plate, preventing the push ring from moving the mold and avoiding deformation damage caused by the mold falling without support. During the reset process of the support platform, the stop block pushes the wedge-shaped slide to move horizontally, thereby causing the vertical locking rod to slide downward, releasing the stop block from the first circular plate. This allows the push ring to smoothly reset the mold to above the support platform, ensuring that the mold is always within the support platform's bearing range, fundamentally eliminating the risk of the mold falling due to the support platform not being reset.

[0034] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0035] like Figure 1 As shown, an aluminum alloy profile heat sink includes a fixed base plate 8, a plurality of heat sinks 9 are fixedly connected at equal intervals to the top of the fixed base plate 8, and a plurality of fixing holes 81 are equally spaced on both sides of the top of the heat sink 9 base plate.

[0036] It should be noted that several heat sinks 9 are distributed along the length of the fixed base plate 8.

[0037] In actual use, the fixing base plate 8 is fixedly installed on the outer surface of the component that needs heat dissipation through several fixing holes 81 on the fixing base plate 8. During this process, the fixing base plate 8 will absorb the heat emitted by the installed component and then conduct the heat to several heat sinks 9. The heat sinks 9 increase the contact area with the air, thereby achieving more efficient heat dissipation.

[0038] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, an aluminum alloy profile heat sink extrusion forming device includes a first pushing mechanism 1, a conveying mechanism 2, a discharge box 3, and a conveying mechanism 7. The first pushing mechanism 1, the conveying mechanism 2, the discharge box 3, and the conveying mechanism 7 are arranged sequentially along the material conveying direction. A driving mechanism 4 is provided below the discharge box 3. The driving mechanism 4 is connected to a support platform 5. The driving mechanism 4 is used to drive the support platform 5 to move along the length direction of the discharge box 3. A mold 6 is slidably connected to the top of the support platform 5. A second pushing mechanism 31 is fixedly installed on the side of the discharge box 3 away from the conveying mechanism 2. A pushing ring 33 is provided inside the discharge box 3. The output shaft of the second pushing mechanism 31 is connected to the pushing ring 33. The second pushing mechanism 31 is used to drive the pushing ring 33 to move along the width direction of the discharge box 3.

[0039] It should be further noted that both the first pushing mechanism 1 and the second pushing mechanism 31 can be linear drive components such as cylinders or hydraulic cylinders. The conveying mechanism 2 includes a support frame and multiple sets of rollers rotatably mounted on the support frame. The multiple sets of rollers are symmetrically distributed along the central axis of the support frame and form an inverted V-shaped structure. The discharge box 3 has a chamber extending through it along its length. The driving mechanism 4 passes through the chamber of the discharge box 3. The side of the discharge box 3 closest to the conveying mechanism 2 is fixedly connected to the feed pipe 310, and the side of the discharge box 3 away from the conveying mechanism 2 is fixedly connected to the discharge pipe 311. The output shaft of the first pushing mechanism 1, the discharge pipe 311, the feed pipe 310, and the central axis of the pushing ring 33 are all on the same horizontal plane. A washer is fixedly connected to the end of the output shaft. The drive mechanism 4 is a lead screw assembly, which is existing technology and will not be described in detail. The support platform 5 is fixedly installed on the slider of the lead screw assembly. There are two second push mechanisms 31. Both second push mechanisms 31 are located on the vertical line of the discharge box 3, and the two second push mechanisms 31 are parallel to the central axis of the discharge pipe 311. The support platform 5 is U-shaped, and a second slot 58 is opened at the middle of the top of the support platform 5 near the conveying mechanism 2. The second slot 58 is opened along the width direction of the discharge box 3. A limit block 62 is fixedly connected to the bottom of the mold 6 near the conveying mechanism 2. The limit block 62 is slidably connected inside the second slot 58. The conveying mechanism 7 is existing technology and will not be described in detail here.

[0040] In actual use, the aluminum feeding mechanism conveys the heated rod-shaped aluminum alloy to the conveying mechanism 2 along the conveying direction. Then, the drive mechanism 4 moves the support platform 5 horizontally into the cavity of the discharge box 3. Next, two second pushing mechanisms 31 are activated, causing the pushing ring 33 to move along the width of the discharge box 3, pushing the mold 6. The mold 6 then moves along the width of the discharge box 3 from the top of the support platform 5 until it is close to the side of the conveying mechanism 2 and fits against the inner wall of the discharge box 3. Then, the first pushing mechanism 1 is activated. The gasket fixedly connected to the output end of the first pushing mechanism 1 pushes the mold 6 located at the top of the conveying mechanism 2. The aluminum rod moves along the length of the conveying mechanism 2. As the aluminum rod enters the feed pipe 310, the gasket also enters the feed pipe 310. With the continuous pushing of the gasket, the aluminum rod, which is heated and has high ductility, passes through the mold 6 and then enters the conveying mechanism 7 through the discharge pipe 311 for discharge, until the aluminum rod completely passes through the mold 6, and then the discharge is completed, that is, the aluminum alloy raw material is extruded into the shape of an aluminum alloy heat sink. Since there is no gap between the second pushing mechanism 31 pushing the mold 6 and the inner wall of the discharge box 3, no aluminum shavings will remain inside the discharge box 3. This can avoid aluminum shavings adhering to the inner wall of the discharge box 3, thereby avoiding aluminum shavings scratching the mold 6 and causing insufficient precision of the extruded finished product in the later stage.

[0041] In the above embodiment, the second pushing mechanism 31 drives the pushing ring 33 to move, and the pushing ring 33 drives the mold 6 to fit tightly against the inner wall of the discharge box 3, thereby preventing the aluminum rod from being squeezed into the gap between the mold 6 and the inner wall of the discharge box 3 when it is being extruded. However, since the mold 6 of the present invention is replaceable, if the mold 6 used on the support platform 5 is still in contact with the inner wall of the discharge box 3 when the mold 6 is replaced, if the support platform 5 is moved by the driving mechanism 4, the mold 6 inside the discharge box 3 will rub against the inner wall of the cavity, which may cause scratches on the side of the mold 6 near the feed pipe 310. As a result, during the subsequent extrusion operation, aluminum will be injected into the scratches left on the side of the mold 6, thus affecting the discharge box 3 cavity. Aluminum shavings left on the wall will, over time, cause increasingly severe scratches on the side of the mold 6, thus affecting the precision of subsequent extruded items. Therefore, in order to solve this problem, in another embodiment of the present invention, the discharge box 3 includes a second rotary plate 34, which is located above the push ring 33 and is fixedly connected to the push ring 33. A flipping plate 35 is rotatably connected to the bottom end of the second rotary plate 34 near the conveying mechanism 2. An abutment baffle 36 is provided on the side of the flipping plate 35 away from the second rotary plate 34. The abutment baffle 36 is connected to the bottom end of the second rotary plate 34, and the abutment baffle 36 and the flipping plate 35 form an abutment limit. A reset block 61 is provided on the side of the mold 6 near the second rotary plate 34, and the reset block 61 is connected to the mold 6.

[0042] It should be added that, such as Figure 5 , Figure 6 , Figure 7 and Figure 9 As shown, the second loop plate 34 is L-shaped, and a rectangular opening is provided through the top of the second loop plate 34. The flip plate 35 is rotatably connected to the inside of the rectangular opening. The length of the flip plate 35 is greater than that of the contact baffle 36. The bottom end of the flip plate 35 and the top end of the reset block 61 are both arc-shaped. The distance between the flip plate 35 and the inner wall of the chamber away from the conveying mechanism 2 is greater than that between the reset block 61 and the inner wall of the chamber away from the conveying mechanism 2.

[0043] In actual use, when the push ring 33 moves the mold 6 along the width of the discharge box 3, the flip plate 35 will first contact the reset block 61. As the push ring 33 continues to move, the flip plate 35 will flip towards the discharge pipe 311 until the bottom of the flip plate 35 passes the top of the reset block 61. Then, due to gravity, the flip plate 35 will flip to a vertical position. As the movement continues, the push ring 33 will contact the side of the mold 6 away from the conveying mechanism 2, and then move the mold 6 until the mold 6 is close to the side of the conveying mechanism 2. One side of the near-conveying mechanism 2 is in contact with the inner wall of the discharge box 3. After the extrusion operation is completed, the second pushing mechanism 31 resets. At that time, the second pushing mechanism 31 will drive the pushing ring 33 to reset. During this process, the pushing ring 33 will drive the second forming plate 34 to reset. During the reset of the second forming plate 34, it will drive the reset block 61, which forms a stop with it, to reset. This will drive the mold 6, which is fixedly connected to the reset block 61, to reset until the stop block 62 completely slides into the second slot 58. At that time, the stop block... Block 62 will abut against the second slot 58, thus preventing the second pushing mechanism 31 from continuing to drive. At this point, the second pushing mechanism 31 will activate, causing the flipping plate 35 to move slightly away from the second pushing mechanism 31, so that the flipping plate 35 and the reset block 61 are no longer in contact. A gap will then exist between the side of the mold 6 near the feed pipe 310 and the inner wall of the discharge box 3. Subsequently, the driving mechanism 4 will move the support platform 5. As the reset block 61 moves, it will lose contact with the flipping plate 35. When the limit is reached, the second pushing mechanism 31 will continue to drive the pushing ring 33 to reset because it loses the limit, until the pushing ring 33 touches the inner wall of the discharge box 3 on the side away from the conveying mechanism 2. The second pushing mechanism 31 is started again to prevent the flipping plate 35 from getting too close to the reset block 61 and the reset block 61 on the replacement mold 6 from touching the flipping plate 35. This reset function can avoid the friction between the mold 6 and the inner wall of the discharge box 3 during the replacement of the mold 6.

[0044] In the above embodiment, the reset of the second pushing mechanism 31 drives the flip plate 35, which forms a resisting and limiting relationship, and the mold reset block 61 to reset. The reset block 61 drives the mold 6, which is fixedly connected to it, to reset, so that the mold 6 does not rub against the inner wall of the discharge box 3 when it is replaced. However, during the extrusion operation, it is impossible to avoid the drive mechanism 4 being accidentally activated. If the drive mechanism 4 moves the support table 5 during the extrusion operation, the mold 6, which is limited by the U-shaped support table 5, will also be moved, thereby interrupting the extrusion operation and turning the extruded product into waste. Therefore, in order to solve this problem, in another embodiment of the present invention, the support... The support platform 5 includes a first motor 51, which is fixedly installed on one side of the support platform 5 near the discharge pipe 311. A first gear 53 and a second gear 54 are rotatably connected to the lower part of the support platform 5. The output end of the first motor 51 is connected to the first gear 53, and the first gear 53 meshes with the second gear 54. A first flipping seat 55 is fixedly connected to the shaft of the first gear 53, and a second flipping seat 56 is fixedly connected to the shaft of the second gear 54. Flipping limit blocks 52 are fixedly connected to both sides of the support platform 5 along its length. A first slot 39 is opened on the inner wall of the discharge box 3 chamber near the conveying mechanism 2, and the limit block 62 is slidably connected to the first slot 39.

[0045] It should be added that, such as Figure 2 , Figure 3 , Figure 4 , Figure 11 and Figure 12 The flipping limiting block 5 is located below the first flipping seat 55 and the second flipping seat 56, and there are two sets of flipping limiting blocks 5. The two sets of flipping limiting blocks 5 respectively form abutment and limiting with the first flipping seat 55 and the second flipping seat 56. The first flipping seat 55 and the second flipping seat 56 are both L-shaped structures. At the same time, the tops of the first flipping seat 55 and the second flipping seat 56 in the initial state are on the same horizontal plane. After flipping, the tops of the first flipping seat 55 and the second flipping seat 56 are both below the top of the support platform 5. The first slot 39 and the second slot 58 have the same shape and the same depth.

[0046] In actual use, after the second pushing mechanism 31 drives the pushing ring 33 to move the mold 6, the limiting block 62 will slide into the first slot 39 along with the movement of the mold 6. At this time, the limiting block 62 will slide out of the second slot 58. Subsequently, the first motor 51 starts, driving the first gear 53 connected to its transmission end to rotate. The first gear 53 will drive the second gear 54 meshing with it to rotate. At that time, the first flipping seat 55 and the second flipping seat 56, which are fixedly connected to the first gear 53 and the second gear 54, will move towards the support. The platform 5 is flipped and unfolded along its length until the first flip seat 55 and the second flip seat 56 are stopped and abutted by the flip limiting plate 59. At that time, even if the drive mechanism 4 is accidentally activated and moves the support platform 5, the first flip seat 55 and the second flip seat 56 will not be able to move the mold 6 because they are not in contact with the mold 6, so as not to affect the extrusion operation of the mold 6. Furthermore, since the mold 6 is slidably connected to the first slot 39 through the limiting block 62 at this time, the mold 6 will not be slightly offset due to the lack of a limit during the extrusion operation.

[0047] In the above embodiment, the U-shaped support platform 5 is configured with a first flip-up seat 55 and a second flip-up seat 56 on both sides, which can be flipped and unfolded. During the extrusion operation, the first motor 51 drives the meshing first gear 53 and second gear 54 to rotate, thereby driving the first flip-up seat 55 and the second flip-up seat 56, which are respectively connected to the first gear 53 and the second gear 54, to flip. This ensures that the tops of the first flip-up seat 55 and the second flip-up seat 56 are both below the top of the support platform 5, ensuring that the support platform 5 will not move against the mold 6 when driven by the drive mechanism 4. However, if the support platform 5 moves due to the accidental activation of the drive mechanism 4, and the extrusion operation of the mold 6 is completed, the mold 6 will fall to the ground if there is no support platform 5 to support it during the reset operation of the second push mechanism 31. This may cause the mold 6 to deform due to the fall, thus affecting the accuracy of the subsequent finished product. Therefore, in order to solve this problem, the present invention... In another embodiment, the discharge box 3 further includes a vertical slide 37 and a receiving slide 38. The receiving slide 38 is formed on the inner wall of the discharge box 3, and the vertical slide 37 is formed inside the discharge box 3. The vertical slide 37 and the receiving slide 38 are interconnected. A vertical locking rod 371 is slidably connected inside the vertical slide 37, and a wedge-shaped slide 381 is slidably connected inside the receiving slide 38. The vertical locking rod 371 and the wedge-shaped slide 381 form a wedge-shaped fit. A spring is installed inside the receiving slide 38. One end of the spring is connected to the wedge-shaped slide 381, and the other end of the spring is connected to the inner wall of the receiving slide 38. The support platform 5 is fixedly connected to the middle of one side of the wedge-shaped slide 381. The contact block 57 and the wedge-shaped slide 381 form a wedge-shaped fit. The first loop plate 32 is located below the push ring 33 and is fixedly connected to the push ring 33. The bottom end of the first loop plate 32 has a rectangular opening. The vertical locking rod 371 and the opening on the first loop plate 32 form a contact limit.

[0048] It should be added that, such as Figure 7 , Figure 8 , Figure 9 and Figure 10 The first circular plate 32 is L-shaped, the end of the contact block 57 near the storage groove 38 and the bottom of the vertical lever 371 are both arc-shaped, the wedge-shaped slide 381 is divided into a long block at the bottom and a short block at the top, the long and short blocks are connected to each other, and the short block is located on the side of the top of the long block away from the support platform 5, and the short block is sloping near the height gradient end of the long block.

[0049] In actual use, after the first flipping seat 55 and the second flipping seat 56 are flipped by the first motor 51, during the subsequent extrusion operation of the mold 6, if the drive mechanism 4 drives the support table 5 to move along the length of the discharge box 3, and after the extrusion operation is completed, the operator moves the support table 5 directly under the mold 6 through the drive mechanism 4. During this process, the abutment block 57 will abut against the wedge-shaped slide table 381. Due to the wedge-shaped fit between the two, the abutment block 57 will push the wedge-shaped slide table 381 deeper into the receiving groove 38. During this period, the higher inclined part of the wedge-shaped slide table 381 will disengage from the bottom of the vertical clamping rod 371. At that time, the vertical clamping rod 371 will slide downwards due to loss of support, thereby disengaging from the rectangular opening on the first eccentric plate 32, thus allowing the vertical clamping rod 371 to disengage from the rectangular opening on the first eccentric plate 32. When the vertical locking rod 371 loses its contact limit with the first circular plate 32, the pushing ring 33 can move along the width direction of the discharge box 3, thereby resetting the mold 6. At the same time, the support platform 5 is also below the mold 6. Therefore, when the support platform 5 is not reset, the spring connecting the wedge slide 381 and the receiving slide 38 will push the wedge slide 381 to move towards the conveying mechanism 2. During this period, the inclined surface on the wedge slide 381 will push the vertical locking rod 371 to slide upward, so that the vertical locking rod 371 extends into the rectangular opening on the first circular plate 32, thereby achieving contact limit on the first circular plate 32, so that the pushing ring 33 cannot move. That is, when the support platform 5 is not moved to the designated position inside the discharge box 3, the pushing ring 33 cannot be reset.
