Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling technology, and in particular to an auxiliary tooling for drying and placing flow channel cores. Background Technology

[0002] Runner cores are used to support the castings during component production and belong to the category of sand cores. After production, a coating is applied to the surface of the runner core to fill the voids on the sand core surface, reduce surface roughness, prevent sand from adhering to the casting surface, and prevent high-temperature damage to the sand core.

[0003] After the application of the coating, the flow channel core needs to be dried. The traditional method is to place the flow channel core on a conveyor belt after the coating surface has solidified, with one side of the flow channel core facing upwards. The flow channel core is dried first on one side and then on the other side. This method makes it impossible to fix the flow channel core in place during the drying process, which can easily cause positional displacement, affecting the stability of the drying process. It can also cause contact damage between flow channel cores, as well as uneven heating and poor drying effect. Utility Model Content

The diameter of the rotating sleeve is smaller than the width of the chain plate. An mounting plate is fixedly connected to the top of the rotating sleeve. Two clamping members are symmetrically arranged above the mounting plate, with a gap between the two clamping members. Each clamping member includes a rotating plate and positioning posts fixed at both ends of the rotating plate. Positioning clips are provided on the opposite side of the positioning posts on the two clamping members. The two positioning clips are combined to form a positioning space for fitting the bottom end of the flow channel core.

[0007] A transmission unit is provided between the rotating sleeve and the conveying device. During the movement of the flow channel core by the conveying device, the rotating sleeve rotates by the transmission unit.

[0008] Preferably, the conveying device includes two symmetrically arranged support frames fixed on the base plate, the drying box is installed between the two support frames, a transmission belt is arranged between the two support frames, the positioning device is arranged on the transmission belt, and a power unit for driving the transmission belt to move is arranged between the transmission belt and the two support frames.

During the movement of the flow channel core on the conveyor belt, the flow channel core is automatically rotated by the transmission unit, ensuring that all surfaces are heated evenly. This eliminates the problems of local overheating or insufficient drying caused by fixed placement in traditional drying methods, and significantly improves the drying quality.

[0019] 2. By utilizing the weight of the flow channel core itself, the two clamping parts rotate relative to each other and retract to limit the position of the flow channel core. This, in turn, allows the positioning clips to limit the components below the flow channel core, preventing the flow channel core from shaking or tipping over during conveying and drying, thus ensuring the drying effect.

[0020] 3. During the rotation of the driven gear, the driving gear will drive the driven gear to achieve intermittent motion, so as to facilitate the replacement of the sand core and ensure the continuous operation of the tooling. Attached Figure Description

[0034] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0035] like Figures 1 to 11 As shown, this utility model provides an auxiliary tooling for drying and placing flow channel cores, including a base plate 1. A support frame for increasing the height of the base plate 1 is provided below the base plate 1. A conveying device for moving the flow channel core 6 is provided above the base plate 1. A drying box 5 is installed above the conveying device. Heating plates are provided on both sides of the drying box 5. Baffles 51 are installed at both ends of the drying box 5 to reduce heat loss inside the drying box 5. The length of the drying box 5 is less than the length of the conveying device. The two ends of the conveying device are provided with a feeding end and a discharging end. Several positioning devices 4 are provided on the conveying device at equal intervals. The flow channel core 6 is vertically fixed on the conveying device by the positioning devices 4 and enters the drying box 5 for drying through the conveying device.

[0036] like Figures 1 to 3 As shown, the conveying device includes two symmetrically arranged support frames 2 fixed on the base plate 1, a drying box 5 installed between the two support frames 2, a transmission belt 3 between the two support frames 2, a positioning device 4 installed on the transmission belt 3, and a power unit for driving the transmission belt 3 to move between the transmission belt 3 and the two support frames 2. In detail, the power unit includes two rotating shafts 33 rotatably installed at both ends between the two support frames 2, a driver 21 installed on one side of one of the support frames 2, the driver 21 being a motor, the driver 21 being connected to one of the rotating shafts 33, and a first transmission gear 32 installed at both ends of the rotating shaft 33, the first transmission gear 32 being located inside the support frame 2, and the transmission belt 3 being formed by a combination of multiple hinged chain plates, with a chain 31 fixedly connected to both ends of the chain plates, which meshes with the first transmission gear 32.

[0037] In the above scheme, the driver 21 causes the rotating shaft 33 to rotate and drives the first transmission gear 32 to rotate. The first transmission gear 32 meshes with the chains 31 at both ends of the chain plate, thereby driving the transmission belt 3 to move along the support frame plate 2, so that the transmission belt 3 rotates in a cycle, transporting the flow channel core 6 from the feeding end to the drying box 5 for drying, and then sending it out from the discharge end, realizing the continuous transport of the flow channel core 6, avoiding manual handling, and improving work efficiency.

[0038] like Figures 5 to 10 As shown, in order to limit the position of the flow channel core 6, in this embodiment, the positioning device 4 includes a rotating sleeve 43, which is perpendicularly arranged to the transmission belt 3. The diameter of the rotating sleeve 43 is smaller than the width of the chain plate. A mounting plate 41 is fixedly connected to the top of the rotating sleeve 43. Two clamping members are symmetrically arranged above the mounting plate 41, with a gap between them. Each clamping member includes a rotating plate 42 and positioning posts 45 fixed to both ends of the rotating plate 42. Positioning clips 451 are provided on opposite sides of the positioning posts 45 on the two clamping members. The positioning clip 451 is assembled to form a positioning space for fitting the bottom end of the flow channel core 6. In detail, two hinge plates 411 are symmetrically connected to both sides of the mounting plate 41. The clamping member is installed between the two hinge plates 411 through the hinge shaft, which is located between the rotating plate 42 and the positioning post 45. In order to facilitate the movement between the clamping member and the mounting plate 41, the outer side of the clamping member has an arc surface. A transmission unit is provided between the rotating sleeve 43 and the support plate 2. During the movement of the flow channel core by the conveying device, the rotating sleeve 43 rotates through the transmission unit.

[0039] In the above scheme, before the position of the flow channel core 6 is defined, the two clamping members are in an inclined state with the two clamping members open outwards. The flow channel core 6 is placed vertically between the two clamping members. Using the weight of the flow channel core 6 itself, the two clamping members rotate relative to each other and close to define the position of the flow channel core 6. In turn, the positioning card 451 defines the extension end 61 below the flow channel core 6, preventing the flow channel core 6 from shaking or tipping over during the conveying and drying process, thus ensuring the drying effect.

[0040] The structure of the clamping component can be adaptively adjusted according to the size of the flow channel core 6, which improves the versatility of the tooling.

[0041] like Figure 2 , Figures 4 to 10 As shown, in order to enable the positioning device 4 to drive the flow channel core 6 to rotate during movement, in this embodiment, the transmission unit includes a guide plate 22 connected to the inner side of the support frame plate 2. The guide plate 22 is located inside the transmission belt 3. The length of the guide plate 22 is greater than the length of the drying box 5 and less than the length of the support frame plate 2. The inner side of the guide plate 22 has a rack 24. A positioning plate 23 is connected below the guide plate 22. The inner side of the positioning plate 23 protrudes from the inner side of the guide plate 22.

[0042] A bearing sleeve 34 is connected to the lower part of the chain plate. A rotating sleeve 43 passes through the chain plate and is located inside the bearing sleeve 34. The lower part of the rotating sleeve 43 protrudes from the bearing sleeve 34, and a second transmission gear 431 that meshes with the rack 24 is fixedly connected to the lower part of the rotating sleeve 43. The diameter of the second transmission gear 431 is smaller than the width of the chain plate. A positioning shaft 44 is slidably connected to the middle part of the rotating sleeve 43. The upper end of the positioning shaft 44 passes through the mounting plate 41. The length of the positioning shaft 44 is greater than the length of the rotating sleeve 43. A clamping plate 442 is connected to the upper end of the positioning shaft 44. A clamping plate 442 is opened on one side of the two rotating plates 42 that is adapted to the clamping plate 442. The slot 421 is provided, and the distance between the two rotating plates 42 is greater than or equal to the diameter of the positioning shaft 44. The lower end of the positioning shaft 44 is fixedly connected to a limiting plate 441 that cooperates with the positioning plate 23. The front end of the guide plate 22 protrudes from the guide plate 22 and has a downward inclined surface so that the limiting plate 441 can quickly be positioned below the positioning plate 23. The two rotating plates 42 are provided with grooves 423 corresponding to the positioning shaft 44 below. In order to better adapt to the positioning shaft 44, in this embodiment, the grooves 423 are arc-shaped and tapered so that the grooves 423 can better fit the positioning shaft 44.

[0043] In the above scheme, when the positioning device 4 is at the feed end of the transmission belt 3 and the front end of the guide plate 22, the transmission belt 3 drives the flow channel core 6 on the positioning device 4 to move, and the second transmission gear 431 gradually meshes with the rack 24 along the inclined surface at the front end of the guide plate 22; as the transmission belt 3 continues to move, the second transmission gear 431 rolls on the rack 24, driving the rotating sleeve 43 to rotate, thereby causing the flow channel core 6 to rotate. The rotation of the flow channel core 6 makes the heating of each surface uniform during the drying process, improving the drying quality of the flow channel core 6; at the same time, before the two clamping parts are closed, the flow channel core 6 contacts the clamping plate 442. When the flow channel core 6 moves downward, the flow channel core 6 passes through The clamping plate 442 makes the limiting plate 441 on the positioning shaft 44 contact the positioning plate 23, so that the limiting plate 441 is located below the positioning plate 23, limiting the position of the clamping plate 442. This limits the clamping plate 442 to the two clamping members, enhancing the stability of the clamping members in clamping the flow channel core 6 during rotation and preventing the flow channel core 6 from moving up and down. When the positioning device 4 leaves the area of ​​the guide plate 22, the flow channel core 6 stops rotating, the second transmission gear 431 disengages from the rack 24, and the limitation on the clamping plate 442 is released. The flow channel core 6 can then be lifted upwards manually or by a robotic arm, and the flow channel core 6 drives the two clamping members to open, thus completing the connection between the flow channel core 6 and the clamping members.

[0044] There are two guide plates 22 arranged symmetrically, and the positioning device 4 has two sets corresponding to the two guide plates 22 respectively, so as to increase the number of flow channel cores 6 to be dried and increase the drying efficiency of flow channel cores 6.

[0045] Working principle:

[0046] In use, the flow channel core 6 is first placed between two clamping parts, that is, between four positioning posts 45, so that the two extension ends 61 at the bottom of the flow channel core 6 are located between two adjacent positioning posts 45, and one of the extension ends 61 is located in the positioning space between two positioning clips 451. At this time, the weight of the flow channel core 6 itself is used to make the two clamping parts rotate and close relative to each other to limit the position of the flow channel core 6, thereby limiting the extension end 61 below the flow channel core 6 by the positioning clips 451, so as to realize the vertical placement of the flow channel core 6.

[0047] Then, the driver 21 drives the transmission belt 3 to move, and the transmission belt 3 drives the flow channel core 6 on the rotating sleeve 43 to move towards the drying box 5. When the second transmission gear 431 on the rotating sleeve 43 meshes with the rack 24 on the inner side of the guide plate 22, the movement of the transmission belt 3 causes the clamping parts and the flow channel core 6 to rotate, so that the flow channel core 6 can be heated evenly in the drying box 5, thereby improving the drying effect.

[0048] At the same time, before the two clamping parts are retracted, the flow channel core 6 contacts the clamping plate 442. The flow channel core 6 moves downward through the clamping plate 442 to make the limiting plate 441 on the positioning shaft 44 contact the positioning plate 23, so that the limiting plate 441 is located below the positioning plate 23, thereby limiting the position of the clamping plate 442.

[0049] When the positioning device 4 leaves the area of ​​the guide plate 22, the flow channel core 6 stops rotating, the second transmission gear 431 disengages from the rack 24, and the restriction on the clamping plate 442 is released. The flow channel core 6 can be lifted upward by manual or mechanical arm, and the flow channel core 6 drives the two clamping parts to open, thus completing the connection between the flow channel core 6 and the clamping parts and completing the entire drying process.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
