Description

Technical Field

[0001] The invention belongs to the technical field of master alloy bar demoulding, in particular to a master alloy bar demoulding device. Background Art

[0002] The manufacturing process of master alloy bars requires pouring the smelted master alloy liquid into a pre-prepared mold. After the master alloy liquid cools and solidifies in the mold to form a bar, the bar is removed from the mold with the help of a demoulding tool. Then, according to actual needs, the bar is further refined to obtain the required shape and size.

[0003] The patent with announcement number CN217192527U discloses a rapid demoulding device for molten steel pouring, including a fixed plate, on which a clamping mechanism for fixing a mother alloy rod mold is arranged, a connecting plate is arranged under the fixed plate, and a plurality of groups of grooves for docking the lower end of the mother alloy rod mold are opened on the connecting plate, and a plurality of groups of ejection mechanisms for demoulding are also arranged on the connecting plate, and the plurality of groups of ejection mechanisms and the plurality of groups of grooves are staggered on the connecting plate. This scheme solves the problem of separation of molten steel pouring and demoulding by enabling the connecting plate to be lifted and lowered and moved laterally, and after the mother alloy rod is demoulded, it is convenient for the staff to clean the grooves and the inside of the mother alloy rod mold.

[0004] In the above scheme, after the master alloy liquid is poured into the master alloy rod mold fixed on the fixed plate, the staff can wait until the master alloy liquid is cooled and solidified before the rod is separated. At this time, if the manufacture of the master alloy rod is to be continued, the used master alloy rod mold needs to be removed, and then a new master alloy rod mold needs to be installed. The installation and disassembly delays a lot of time, making it impossible to continuously manufacture the master alloy rod, thereby reducing the manufacturing efficiency of the master alloy rod. Secondly, before the mold is used, a release agent is applied to the inside of the mold to facilitate the demolding of the master alloy rod, but the lower end of the mold is connected to the groove, and the groove is not coated with a release agent, making it difficult to separate the lower end of the mold from the groove, and forced separation will affect the quality of the joint between the rod and the groove; for this reason, the present invention provides a master alloy rod demolding device. Summary of the invention

[0009] As long as a suitable first spring is selected, not only can the sealing between the slide plate and the lower end of the mold be ensured, but also excessive extrusion force between the slide plate and the lower end of the mold can be avoided, thereby increasing the service life of the sealing plate and the mold.

[0011] The pawl drives the ratchet wheel to rotate together with the transmission shaft, and the transmission shaft drives the scraper bar to rotate 180 degrees along the plate body, so that the mother alloy debris remaining on the plate body is scraped off by the scraper bar, thereby cleaning the plate body, thereby eliminating the influence of the mother alloy debris on the coating agent roller brush and ensuring the manufacturing quality of the mother alloy rod.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. Before casting the master alloy liquid, the release agent is applied to the sealing plate by a brushing roller, which is not only conducive to the separation of the sealing plate from the lower end of the mold, but also ensures the quality of the rod. Secondly, by driving the conversion disk to rotate, the sealing plate can be automatically flipped under the cooperation of the receiving rod and the annular groove.

[0014] 2. Under the guidance of the concave groove, the receiving rod will push the pressure plate, and the pressure plate will push the slide plate to slide along the guide rail through the first spring. At the same time, the slide plate drives the transmission gear to rotate to realize the above-mentioned flipping of the sealing plate. When the slide plate contacts the lower port of the mold, the pressure plate will push the guide column to move and compress the first spring. The rebound force of the first spring acts on the slide plate to seal the slide plate and the lower port of the mold. Therefore, as long as a suitable first spring is selected, it can not only ensure the sealing between the slide plate and the lower port of the mold, but also avoid excessive extrusion force between the slide plate and the lower port of the mold, thereby increasing the service life of the sealing plate and the mold.

[0015] 3. After the mother alloy rod in the mold is formed, when it is necessary to release the sealing plate on the lower port of the mold, the sealing plate flips back, and the end of the push rod still slides along the inclined surface on the arc block, and the push rod is pushed by the inclined surface, so that the push rod pushes the movable sleeve to slide along the rectangular axis toward the inside of the transmission sleeve and compresses the second spring. At the same time, the two sets of pins slide along the spiral groove respectively, so that the transmission sleeve rotates together with the first bevel gear and the second bevel gear. At this time, the teeth on the ratchet hinder the pawl, so that the pawl drives the ratchet to rotate together with the transmission shaft, and the transmission shaft drives the scraper bar to rotate 180 degrees along the plate body, so that the mother alloy debris remaining on the plate body is shoveled off by the scraper bar, so as to clean the plate body, thereby eliminating the influence of the mother alloy debris on the coating agent roller brush and ensuring the manufacturing quality of the mother alloy rod.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0026] Embodiment 1: Figures 1 to 3 As shown, a mother alloy bar demoulding device described in an embodiment of the present invention comprises a frame 1, a fixed plate 2 is fixedly installed in the frame 1, a conversion plate 3 is rotatably installed on the fixed plate 2, three groups of discharge troughs 31 for placing molds 4 are opened on the outer ring of the conversion plate 3, a hydraulic cylinder 5 is arranged just above one group of discharge troughs 31, and the lower end of the hydraulic cylinder 5 is fixedly connected to the frame 1, three groups of blocking mechanisms 6 are arranged on the lower end surface of the conversion plate 3, a demoulding agent box 7 is fixedly installed on the fixed plate 2, three groups of brush rollers 8 are rotatably installed in the demoulding agent box 7, the blocking mechanism 6 comprises a blocking plate 601, both sides of the blocking plate 601 are connected with a rotating shaft 602, the rotating shaft 602 is rotatably connected to the support plate 603, and the support plate 604 is connected to the support plate 603. 03 is fixedly connected to the lower end face of the conversion disk 3, a transmission gear 604 fixedly mounted on a set of rotating shafts 602, a tooth plate 605 meshing with the transmission gear 604, a receiving rod 606 fixedly connected to one end of the tooth plate 605, a guide rail 607 slidably connected to the tooth plate 605, the guide rail 607 is fixedly connected to the lower end face of the conversion disk 3, a feed hole 21 is provided on the fixed disk 2, the feed hole 21 is located directly below the hydraulic cylinder 5, and an annular groove 22 is provided on the fixed disk 2, the lower end of the receiving rod 606 is located in the annular groove 22, the annular groove 22 is composed of an arc groove 221 and a concave groove 222, a feed plate 32 is attached to the edge of the upper end face of the conversion disk 3, and the lower end of the feed plate 32 is fixedly connected to the fixed disk 2.

[0027] Specifically, the frame 1 is in a semi-open state, the demoulding agent box 7 stores the demoulding agent, the brush roller 8 itself is mostly immersed in the demoulding agent, the aperture of the discharge hole 21 is larger than the outer diameter of the mold 4, and in the initial state, one set of discharge troughs 31 is located between the hydraulic cylinder 5 and the discharge hole 21, and the other set of discharge troughs 31 is placed in the non-shielded area of ​​the frame 1. When it is necessary to manufacture the master alloy bar, the conversion disk 3 is driven by the motor to rotate 120 degrees, and the lower attached Figure 1 The direction indicated by the middle arrow is the rotation direction of the conversion disk 3, so that a group of discharge troughs 31 are transferred to the non-blocked area of ​​the frame 1, and at the same time, the three groups of blocking mechanisms 6 rotate together with the conversion disk 3. During the rotation process, a blocking plate 601 on a group of blocking mechanisms 6 will pass above the demoulding agent box 7, and the lower end surface of the blocking plate 601 moves against the three groups of brush rollers 8 in the demoulding agent box 7, so that the three groups of brush rollers 8 rotate, and the rotating brush rollers 8 roll the demoulding agent in the demoulding agent box 7 onto the lower end surface of the blocking plate 601, and then insert the mold 4 with the demoulding agent applied inside into a group of discharge troughs 31, and then drive the conversion disk 3 to continue After the material discharge trough 31 is rotated for 120 degrees, the lower end of the receiving rod 606 corresponding to the lower part of the material discharge trough 31 will enter the concave groove 222 from the arc groove 221. Under the guidance of the concave groove 222, the receiving rod 606 drives the tooth plate 605 to move along the guide rail 607 toward the axis of the conversion disk 3. At the same time, the tooth plate 605 drives the transmission gear 604, a set of rotating shafts 602, and the blocking plate 601 to rotate together, so that the blocking plate 601 rotates 180 degrees. The surface of the blocking plate 601 with the release agent will be close to the lower port of the mold 4. At this time, the master alloy liquid is poured into the mold 4. While waiting for the master alloy liquid to cool and solidify. , the next set of molds 4 can be inserted into the next set of discharge troughs 31. After the mother alloy rods in the mold 4 are formed, the conversion disk 3 is driven to rotate 120 degrees again to rotate the mold 4 to the bottom of the hydraulic cylinder 5. During this process, the blocking plate 601 will flip back to release the blocking of the lower port of the mold 4 by the blocking plate 601, and then the hydraulic cylinder 5 will be started. The end of the hydraulic cylinder 5 will press down the mother alloy rods formed in the mold 4, so that the mother alloy rods are separated from the mold 4 and discharged through the discharge hole 21. Then the conversion disk 3 is driven to rotate 120 degrees. During the rotation process, the mold 4 will enter the non-blocking area of ​​the frame 1, and the mold The upper end of the mold 4 will be squeezed by the blanking plate 32, so that the mold 4 will automatically separate from the corresponding discharge trough 31, and then the above operation will be repeated in a cycle. Compared with the prior art, before casting the mother alloy liquid, the release agent is brushed on the sealing plate 601 by the brushing roller 8, which is not only conducive to the separation of the sealing plate 601 from the lower end of the mold 4, but also ensures the quality of the rod. Secondly, by driving the conversion disk 3 to rotate, under the cooperation of the receiving rod 606 and the annular groove 22, the sealing plate 601 can be automatically flipped, and the mold 4 can be sequentially cast, demolded and blanked, thereby improving the manufacturing efficiency of the mother alloy rod.

[0028] like Figure 4As shown, the tooth plate 605 includes a slide plate 6051, the slide plate 6051 is slidably connected to the guide rail 607, a guide column 6052 movably inserted in the slide plate 6051, a first spring 6053 sleeved on the guide column 6052, a pressure plate 6054 fixedly connected to one end of the guide column 6052, the pressure plate 6054 is slidably connected to the inner cavity of the slide plate 6051, one side of the pressure plate 6054 is fixedly connected to the receiving rod 606, the slide plate 6051 meshes with the transmission gear 604, and the first spring 6053 is located between the pressure plate 6054 and the inner wall of the slide plate 6051.

[0029] Specifically, the above-mentioned direct flipping of the blocking plate 601 and the close contact with the lower end of the mold 4 will cause the blocking plate 601 and the lower end of the mold 4 to have too much extrusion pressure in the contact area, thereby causing the blocking plate 601 and the mold 4 to wear more in the contact area, reducing the service life of the blocking plate 601 and the mold 4. Therefore, under the guidance of the concave groove 222, the receiving rod 606 will push the pressure plate 6054, and the pressure plate 6054 will push the slide plate 6051 to slide along the guide rail 607 through the first spring 6053. At the same time, the slide plate 6051 drives the transmission gear 604 to rotate, so as to achieve the above-mentioned blocking plate 601. 01 is flipped, when the slide plate 6051 contacts the lower port of the mold 4, the pressure plate 6054 will push the guide column 6052 to move and compress the first spring 6053. The rebound force of the first spring 6053 acts on the slide plate 6051, so that the slide plate 6051 and the lower port of the mold 4 are sealed. Therefore, as long as a suitable first spring 6053 is selected, it can not only ensure the sealing between the slide plate 6051 and the lower port of the mold 4, but also avoid excessive extrusion pressure between the slide plate 6051 and the lower port of the mold 4, thereby increasing the service life of the sealing plate 601 and the mold 4.

[0030] Embodiment 2: Figures 5 to 7As shown, compared with Example 1, another implementation of the present invention is: the blocking plate 601 includes a plate body 6011, two sets of rotating shafts 602 are respectively installed on both sides of one end of the plate body 6011, a rectangular shaft 6012 fixedly installed in the plate body 6011, a movable sleeve 6013 movably sleeved on the rectangular shaft 6012, a transmission sleeve 6015 rotatably sleeved on the end of the rectangular shaft 6012, a second spring 6014 arranged between the transmission sleeve 6015 and the movable sleeve 6013, a first bevel gear 6016 fixedly sleeved on the end of the transmission sleeve 6015, a second bevel gear 6017 meshing with the first bevel gear 6016, a transmission shaft 6018 connected to one end of the second bevel gear 6017, and a scraper strip 6019 fixedly connected to the end of the transmission shaft 6018, and the scraper strip 6019 is close to the plate body 6011. The transmission sleeve 6015 is plugged into the movable sleeve 6013. Two groups of spiral grooves 151 are provided on the outer ring of the transmission sleeve 6015. Two groups of pins 132 are provided on the outer ring of the movable sleeve 6013. The two groups of pins 132 are respectively located in the two groups of spiral grooves 151. A docking groove 171 is provided at one end of the second bevel gear 6017. Three groups of pawls 172 are hinged at equal angles in the docking groove 171. The pawls 172 are clamped with ratchet wheels 173. The middle part of the ratchet wheel 173 is fixedly connected to the transmission shaft 6018. An arc block 6031 is provided on one group of support plates 603. The arc block 6031 is provided with an inclined surface 311. A push rod 131 is provided at one end of the movable sleeve 6013. The end of the push rod 131 is close to the inclined surface 311. The push rod 131 is movably plugged into the plate body 6011, and the transmission shaft 6018 is rotatably installed in the plate body 6011.

[0031] Specifically, the ratchet 173 is made of a magnet, and the ratchet 173 has an adsorption force on the pawl 172. Although the coating agent is rolled on the sealing plate 601, in the initial state, the second spring 6014 is in a compressed state. However, when the sealing plate 601 is separated from the lower port of the mold 4, a small amount of mother alloy debris will still remain on the sealing plate 601. As the mother alloy debris accumulates on the sealing plate 601, it not only affects the coating agent rolling on the sealing plate 601, but also affects the manufacturing quality of the mother alloy rod. Therefore, in the process of the sealing plate 601 blocking the lower port of the mold 4, under the action of the rebound force of the second spring 6014 , the end of the push rod 131 will always slide along the inclined surface 311 on the arc block 6031, and the movable sleeve 6013 will move along the rectangular shaft 6012 toward the arc block 6031, and the movable sleeve 6013 drives the two sets of pins 132 to slide along the two sets of spiral grooves 151 on the transmission sleeve 6015, respectively, so that the transmission sleeve 6015 and the first bevel gear 6016 rotate, and the rotating first bevel gear 6016 drives the second bevel gear 6017 and the four sets of pawls 172 to rotate. At this time, the teeth on the ratchet 173 cannot hinder the pawl 172, and because the scraper strip 6019 is close to the plate The body 6011 makes friction between the scraper 6019 and the plate body 6011, so that the ratchet 173 cannot rotate easily. On the contrary, when the mother alloy bar in the mold 4 is formed and it is necessary to release the blocking of the lower port of the mold 4 by the blocking plate 601, the blocking plate 601 is turned back, and the end of the push rod 131 still slides along the inclined surface 311 on the arc block 6031, and the push rod 131 is pushed by the inclined surface 311, so that the push rod 131 pushes the movable sleeve 6013 to slide along the rectangular shaft 6012 toward the inside of the transmission sleeve 6015, and compresses the second spring 6014. At the same time, the two sets of pins 132 slides along the spiral groove 151 respectively, so that the transmission sleeve 6015 rotates together with the first bevel gear 6016 and the second bevel gear 6017. At this time, the teeth on the ratchet 173 hinder the pawl 172, so that the pawl 172 drives the ratchet 173 to rotate together with the transmission shaft 6018. The transmission shaft 6018 drives the scraper 6019 to rotate 180 degrees along the plate body 6011, so that the mother alloy debris remaining on the plate body 6011 is scraped off by the scraper 6019, so that the plate body 6011 is cleaned, thereby eliminating the influence of the mother alloy debris on the coating agent roller brush, and ensuring the manufacturing quality of the mother alloy rod.

[0032] Working principle: The motor drives the conversion disk 3 to rotate 120 degrees, and the lower part is attached Figure 1The direction indicated by the middle arrow is the rotation direction of the conversion disk 3, so that a set of discharge troughs 31 are transferred to the non-blocking area of ​​the frame 1, and at the same time, the three sets of blocking mechanisms 6 rotate together with the conversion disk 3. During the rotation process, a blocking plate 601 on a set of blocking mechanisms 6 will pass above the demoulding agent box 7, and the lower end surface of the blocking plate 601 moves against the three sets of brush rollers 8 in the demoulding agent box 7, so that the three sets of brush rollers 8 rotate, and the rotating brush rollers 8 roll the demoulding agent in the demoulding agent box 7 to the lower end of the blocking plate 601. The mold 4 with the release agent applied inside is then inserted into a set of discharge grooves 31, and then the conversion disk 3 is driven to continue to rotate 120 degrees. The lower end of the corresponding receiving rod 606 below the discharge groove 31 enters the concave groove 222 from the arc groove 221. Under the guidance of the concave groove 222, the receiving rod 606 drives the tooth plate 605 to move along the guide rail 607 toward the axis direction of the conversion disk 3. At the same time, the tooth plate 605 drives the transmission gear 604, a set of rotating shafts 602, and the blocking plate 606. 01 rotates together, so that the blocking plate 601 rotates 180 degrees, and the surface of the blocking plate 601 with the release agent will be close to the lower port of the mold 4. At this time, the mother alloy liquid is poured into the mold 4. While waiting for the mother alloy liquid to cool and solidify, the next group of molds 4 can be inserted into the next group of discharge troughs 31. After the mother alloy rods in the mold 4 are formed, the conversion disk 3 is driven to rotate 120 degrees again, so that the mold 4 is rotated to the bottom of the hydraulic cylinder 5. During this process, the blocking plate 601 will flip back to release the blocking of the lower port of the mold 4 by the blocking plate 601, and then the hydraulic cylinder 5 is started. The end of the hydraulic cylinder 5 will press down the mother alloy rod formed in the mold 4, so that the mother alloy rod is separated from the mold 4 and discharged through the discharge hole 21. Then the conversion disk 3 is driven to rotate 120 degrees. During the rotation process, the mold 4 will enter the non-blocking area of ​​the frame 1. At the same time, the upper end of the mold 4 will be squeezed by the discharge plate 32, so that the mold 4 automatically separates from the corresponding discharge trough 31, and then the above operation is repeated in a cycle;

[0033] Under the guidance of the concave groove 222, the receiving rod 606 pushes the pressing plate 6054, and the pressing plate 6054 pushes the sliding plate 6051 to slide along the guide rail 607 through the first spring 6053. At the same time, the sliding plate 6051 drives the transmission gear 604 to rotate, so as to realize the above-mentioned flipping of the blocking plate 601. When the sliding plate 6051 contacts the lower end of the mold 4, the pressing plate 6054 pushes the guide column 6052 to move and compresses the first spring 6053. The rebound force of the first spring 6053 acts on the sliding plate 6051, so that the sliding plate 6051 and the lower end of the mold 4 are sealed.

[0034] During the process of the blocking plate 601 blocking the lower port of the mold 4, under the rebound force of the second spring 6014, the end of the push rod 131 will always slide against the inclined surface 311 on the arc block 6031, and the movable sleeve 6013 will move along the rectangular shaft 6012 toward the arc block 6031, and the movable sleeve 6013 drives the two groups of pins 132 to slide along the two groups of spiral grooves 151 on the transmission sleeve 6015 respectively, so that the transmission sleeve 6015 and the first bevel gear 6016 rotate, and the rotating first bevel gear 6016 drives the second bevel gear 6017 and the four groups of pawls 172 to rotate. At this time, the teeth on the ratchet 173 cannot hinder the pawl 172, and because the scraper 6019 is close to the plate body 6011, there is friction between the scraper 6019 and the plate body 6011, so that the ratchet 173 cannot rotate easily. On the contrary, after the mother alloy bar in the mold 4 is formed, When the blocking of the lower port of the mold 4 by the blocking plate 601 needs to be released, the blocking plate 601 is turned back, and the end of the push rod 131 still slides along the inclined surface 311 on the arc block 6031, and the push rod 131 is pushed by the inclined surface 311, so that the push rod 131 pushes the movable sleeve 6013 to slide along the rectangular shaft 6012 toward the inside of the transmission sleeve 6015, and compresses the second spring 6014, and at the same time, the two sets of pins 132 are respectively moved along the rectangular shaft 6012. The spiral groove 151 slides, causing the transmission sleeve 6015 to rotate together with the first bevel gear 6016 and the second bevel gear 6017. At this time, the teeth on the ratchet 173 hinder the pawl 172, causing the pawl 172 to drive the ratchet 173 to rotate together with the transmission shaft 6018. The transmission shaft 6018 drives the scraper 6019 to rotate 180 degrees along the plate body 6011, so that the mother alloy debris remaining on the plate body 6011 is scraped off by the scraper 6019.
