Description

Technical Field

[0001] The present invention relates to the technical field of drying, and particularly relates to a white mold drying production line for lost foam casting of a new energy commercial vehicle gearbox housing. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as the power source. As commercial vehicles, they can effectively save costs. Their gearbox housings mainly adopt the lost foam casting process. The lost foam casting process is a precision casting technology with a foam plastic model as the main body of the mold. Its core principle is that high-temperature molten metal vaporizes the model and occupies its space to form a casting. This process combines physical forming and chemical treatment technologies and is widely used in the field of mechanical manufacturing, especially having significant advantages in the production of high-precision and complex-structured castings.

[0003] The white mold is the core forming carrier in lost foam casting. It needs to go through pre-foaming and forming, cutting and bonding, refractory coating treatment and drying, and finally be placed in a sand box for pouring. In the prior art, after the white mold is dip-coated with refractory coating, it is usually manually moved to a drying bracket, drained and then dried. However, since there will be a large amount of coating dripping on the surface of the white mold just taken out, it needs to be drained first, and then the drained mold is placed on the bracket for drying. The draining is usually carried out independently, which is rather time-consuming. Summary of the Invention

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figure 1As shown in the figure, a white mold drying production line for lost foam casting of a new energy commercial vehicle gearbox housing provided by an embodiment of the present invention includes a coating area 1 and a drying area 3. A track 2 is provided between the coating area 1 and the drying area 3. There are several coating tanks 4 in the coating area 1. A drying bracket 5 is slidably provided on the track 2. The drying bracket 5 is used to place the white mold after being coated with refractory material. After the drying bracket 5 is filled, it moves on the track 2 to the drying area 3 for drying. Drying mechanisms 6 are provided on both sides in the drying area 3. The drying mechanisms 6 continuously output hot air to dry the coated white mold.

[0034] During the processing of the white mold of the lost foam pattern, it is necessary to dip the refractory coating multiple times to enhance its surface strength and air permeability and then perform the drying treatment. After the white mold is dipped in the refractory coating, it is necessary for workers to move the white mold full of coating to the bracket manually. When the white mold is just taken out, a large amount of coating will drip from its surface. It is necessary for the staff to hold it for a period of time until the liquid flow rate on the surface becomes smaller, or directly move it to the bracket for draining. The former is likely to increase the workload of the staff and is also a waste of time. The latter, during the moving process, the liquid on the surface of the white mold is likely to drip to the ground, causing pollution and waste of resources. Therefore, this embodiment proposes a drying bracket 5, which cooperates with an arc-shaped draining groove 505 and an arc-shaped material receiving groove 51102 to realize the material receiving and draining of the dipped white mold, effectively saving time and manpower.

[0035] As Figure 2 shown in the figure, the drying bracket 5 includes a bottom support frame 501. A rectangular sliding groove 503 is opened on the bottom support frame 501. A telescopic support 504 is slidably provided on the rectangular sliding groove 503. An arc-shaped draining groove 505 is detachably installed at the top end of the telescopic support 504. Universal wheels 502 are installed on both sides of the bottom end of the bottom support frame 501. A driving mechanism is also installed at the bottom end of the bottom support frame 501. The drying bracket 5 realizes the movement on the track 2 through the driving mechanism. Specifically, the driving mechanism includes a driving wheel rotatably provided. The driving wheel is driven by a motor. The driving wheel contacts the track 2 to realize the movement on the track 2. A rectangular mounting plate 506 is fixedly provided at the middle position on the bottom support frame 501. A cylindrical sliding rod 507 is fixedly provided on the rectangular mounting plate 506. A top cover 508 is detachably installed at the top end of the cylindrical sliding rod 507. A long sliding groove 509 is also slidably provided on the cylindrical sliding rod 507. A plurality of placing components 510 are slidably provided on the long sliding groove 509. The plurality of placing components 510 can slide in the long sliding groove 509. The placing components 510 are used to place the coated lost foam white mold. As Figure 3As shown, the arc-shaped draining tank 505 includes an arc-shaped tank plate 50501. An outlet 50502 is also provided at one end of the arc-shaped tank plate 50501. A scraper 50503 is slidably arranged inside the arc-shaped tank plate 50501. The scraper 50503 is attached to the inner wall of the arc-shaped tank plate 50501 and is used to scrape the paint inside the arc-shaped tank plate 50501 clean. A draining support 511 is also equipped on the drying support 5. The draining support 511 is detachably connected to the bottom support frame 501 on the drying support 5. The detachable connection method includes snap connection. The draining support 511 includes a main support 51101. A number of arc-shaped material receiving grooves 51102 are slidably arranged on the main support 51101. The number of a number of arc-shaped material receiving grooves 51102 is the same as the number of a number of placing components 510. In this embodiment, when in use, the previous number of placing components 510 are initially located at the top position of the cylindrical sliding rod 507 and are successively moved to the position above the paint pool 4 during use. The staff can directly place the dip-coated white mold on the placing component 510 and realize the successive feeding of the dip-coated white mold by rotating the placing component 510. The dip-coated white mold moves along the direction of the arc-shaped draining tank 505. The just-coated white mold first enters the arc-shaped draining tank 505 for preliminary draining. The liquid generated by draining enters the arc-shaped draining tank 505 and is scraped back to the paint pool 4 through the scraper 50503. The draining support 511 is used for secondary draining. The liquid generated during draining is collected by the arc-shaped material receiving grooves 51102 and then recycled.

[0036] In the conventional white mold placing support, the distance between each layer is fixed and cannot be adjusted. It is necessary for people to stack the white molds on it. The staff needs to bend down or climb high repeatedly for placing, and the operation is relatively inconvenient. Therefore, this application proposes a slidable placing component 510. The distance between each placing component 510 can be independently adjusted to realize the stacking of white molds.

[0037] As Figure 4 shown, the cylindrical sliding rod 507 includes an annular side wall 50701. A cavity is provided inside the cylindrical sliding rod 507. A partition plate 50702 is fixedly arranged at the inner diameter of the annular side wall 50701, dividing the cavity into two parts. A rack 50703 is fixedly arranged on the partition plate 50702. Two long sliding grooves 509 are symmetrically arranged on the annular side wall 50701 at positions perpendicular to the partition plate 50702.

[0038] As Figure 5 and Figure 6As shown, the storage component 510 includes an annular inner plate 51001. Inside the annular inner plate 51001, a first slider 51017 and a second slider 51018 are fixedly provided. The first slider 51017 and the second slider 51018 are respectively slidably connected to two long chutes 509 on the cylindrical slide bar 507. A first pulley 51019 is rotatably provided on the first slider 51017. At both ends of the first pulley 51019, two gears 51020 are coaxially and fixedly connected through a connecting shaft. At the top end of the first slider 51017, a first motor 51022 is fixedly provided. The output end of the first motor 51022 is fixedly connected to a second pulley 51023. The first pulley 51019 and the second pulley 51023 are connected by a timing belt 51021, and both gears 51020 are engaged with the rack 50703 (as Figure 4 shown). When in use, the first motor 51022 operates to drive the two gears 51020 to rotate. The meshing transmission between the gears 51020 and the rack 50703 realizes the movement of the storage component 510 on the cylindrical slide bar 507.

[0039] Regarding the problem that the white molds need to be evenly stacked during the actual operation process after dip coating, in this embodiment, a number of storage meshes 51011 are provided and cooperate with springs 51015 to achieve the equidistant arrangement of each storage mesh 51011, and the number of storage meshes 51011 can also be adjusted.

[0040] As Figures 5 - 8 shown, the annular inner plate 51001 is slidably provided with an annular chute 51003 through an L-shaped limiting member 51002. The annular chute 51003 is fixedly connected to the L-shaped limiting member 51002. A first annular limiting groove 51016 is formed on the top end surface of the annular inner plate 51001, that is, the annular chute 51003 can move in a circular motion along the annular inner plate 51001. An inverted frustum-shaped limiting member 51012 is also slidably provided outside the annular inner plate 51001. At the bottom end surface of the inverted frustum-shaped limiting member 51012, a circular tube 51013 is fixedly provided. The diameter of the top circle of the circular tube 51013 is larger than the diameter of the bottom circle (as Figure 8 shown). The inverted frustum-shaped limiting member 51012 is slidably provided between the annular inner plate 51001 and the annular chute 51003. A circular mounting plate 51004 is also fixedly provided at the connection between the inverted frustum-shaped limiting member 51012 and the circular tube 51013. A number of cylindrical blocking rods 51014 are fixedly provided on the circular mounting plate 51004. The distance between the a number of cylindrical blocking rods 51014 is equal, that is, the inverted frustum-shaped limiting member 51012, the circular mounting plate 51004 and the circular tube 51013 are integrated and can move up and down synchronously along the annular inner plate 51001.

[0041] As Figure 7 and Figure 6As shown, a U-shaped piece 51005 is fixedly provided on the annular chute 51003. A clamping piece 51006 is rotatably provided on the U-shaped piece 51005. An annular sliding rod 51007 is also provided outside the annular chute 51003. The annular sliding rod 51007 is provided with an opening. One end thereof is fixedly connected to the U-shaped piece 51005, and the other end is clamped on the clamping piece 51006, as Figure 9 and Figure 10 shown. When the clamping piece 51006 rotates upward, the clamping piece 51006 is separated from the open end of the annular sliding rod 51007. At this time, the open end of the annular sliding rod 51007 will be exposed, facilitating the installation of other accessories on the annular sliding rod 51007.

[0042] As Figure 5 shown, a plurality of connecting pieces 51008 are slidably provided on the annular sliding rod 51007. The plurality of connecting pieces 51008 are all slidably connected to the annular chute 51003. Inclined rods 51009 are fixedly provided on the plurality of connecting pieces 51008. Air blowers 51010 are fixedly provided at the tops of the plurality of inclined rods 51009. Object placing nets 51011 are fixedly provided on the plurality of air blowers 51010. The object placing nets 51011 are specifically in the shape of an uncapped cylinder and are used for placing the coated white film. Springs 51015 are sleeved between the plurality of connecting pieces 51008. The plurality of springs 51015 are all sleeved outside the annular sliding rod 51007. A plurality of cylindrical stop rods 51014 are also respectively located between the plurality of connecting pieces 51008.

[0043] As Figure 5 and Figure 6 shown, during use, the springs 51015 are in a compressed state. The plurality of cylindrical stop rods 51014 are respectively located on one side of the plurality of inclined rods 51009 to limit the inclined rods 51009 and prevent the inclined rods 51009 from sliding along the annular sliding rod 51007 under the action of the springs 51015. At the same time, when the circular mounting plate 51004 is rotated, the cylindrical stop rods 51014 will rotate synchronously with the circular mounting plate 51004. Under the push of the cylindrical stop rods 51014, the plurality of inclined rods 51009 will move synchronously, and the springs 51015 are always in a compressed state, further realizing the movement of the plurality of object placing nets 51011, as Figure 3As shown, the storage net 51011 is successively moved above the paint tank 4. The operator places the white mold dipped with fireproof paint on the storage net 51011, and the storage net 51011 moves towards the arc-shaped draining tank 505. A large amount of liquid paint will drip from the surface of the just-placed white mold, and these paints drip into the arc-shaped draining tank 505 and are scraped back into the paint tank 4 for recycling. When the dripping speed of the liquid on the surface of the white mold decreases, several storage nets 51011 are rotated to the arc-shaped material receiving tank 51102 for secondary draining. The arc-shaped material receiving tank 51102 can be slidably removed from the main support 51101. After the initial draining of each group of storage nets 51011, the corresponding arc-shaped material receiving tank 51102 is slidably inserted onto the main support 51101. Each group of arc-shaped material receiving tanks 51102 is located below the corresponding storage net 51011 for convenient secondary draining. During the secondary draining process, the drying support 5 can move along the track 2 into the drying area 3. Before entering the drying area 3, the operator removes the arc-shaped material receiving tank 51102 to recycle the paint inside, and the drying support 5 enters the drying area 3 for drying.

[0044] As Figure 8 shown, vertical rods 51024 are fixedly provided at the bottom of the annular chutes 51003 of the top cover 508 and several storage components 510 (there is no vertical rod 51024 on the lowermost storage component 510).

[0045] When white molds after dip coating are placed on a number of storage components 510, then control the downward movement of the number of storage components 510 one by one. When the first group of storage components 510 moves to the lowest position, control the second group of storage components 510 to move downward. During the movement, the bottom vertical rod 51024 of the second group of storage components 510 will contact the top surface of the frustum-shaped limiting member 51012 on the storage component 510 below it and push the frustum-shaped limiting member 51012 downward. The annular cylinder 51013 and the frustum-shaped limiting member 51012 move downward synchronously until the cylindrical stop rod 51014 fixedly connected to the annular cylinder 51013 separates from the connecting member 51008, the spring 51015 resumes deformation, a number of connecting members 51008 lose resistance, and under the action of the spring 51015, they slide along the annular slide rod 51007, realizing the equidistant movement of a number of storage nets 51011. When the frustum-shaped limiting member 51012 moves to the lowest position, it will contact a number of connecting members 51008 and squeeze them to prevent the number of connecting members 51008 from moving easily, thus realizing the position fixation of the storage nets 51011. Similarly, when a number of storage nets 51011 need to be gathered, the spring 51015 can be manually squeezed and the annular slide rod 51007 can be moved upward to realize the gathering and limiting of a number of storage nets 51011. When a number of storage nets 51011 are gathered, it is convenient to drain the white molds coated on them, and the equidistant dispersion of a number of storage nets 51011 can realize the drying of the white molds on them, further ensuring that the drying time of each white mold is almost the same. A number of air blowers 51010 can blow air upward, which can further ensure that the white molds in contact with the storage nets 51011 can be quickly dried, avoiding the phenomenon of uneven drying.
