For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0023] Reference Figure 1 to Figure 6 , which is an embodiment of the present invention, provides a core shooting machine for iron pad casting, including a frame 1, a mold 2 and a mold opening and closing mechanism 3, and also includes: a demolding mechanism 4, the demolding mechanism 4 is arranged on the frame 1, the demolding mechanism 4 is located on one side of the mold 2, after the mold opening and closing mechanism 3 drives the mold 2 to open, the demolding mechanism 4 is used to take out the core; the demolding mechanism 4 includes: a support 40, which is arranged on the frame 1 and the support 40 is located at the bottom of the mold 2; a swinging member 5, which is slidably arranged on the support 40; a material taking member 6, which is rotatably arranged on the swinging member 5, and the material taking member 6 is used to absorb the core and take the core out of the mold 2.

[0024] In the above scheme, the demoulding mechanism 4 includes a support 40, a swinging member 5 and a material taking member 6. The support 40 is arranged on the frame 1 and is located at the bottom of the mold 2. The support 40 plays the role of fixing and supporting the swinging member 5. The swinging member 5 is slidably arranged on the support 40, and can slide up and down or forward and backward within a certain range, so that the material taking member 6 can flexibly enter the mold 2 or move to different positions of the mold 2 to adapt to cores of different shapes and sizes. The material taking member 6 is rotatably arranged on the swinging member 5, and the material taking member 6 has a material taking end, and the material taking end can firmly absorb the core. When the mold opening and closing mechanism 3 opens the mold 2, the swinging member 5 first swings once with an empty rod, and the material taking member 6 is located on one side of the swinging member 5 at this time. The purpose of the empty rod swinging is to knock off the excess material column located at the inlet of the mold 2, and then when the swinging member 5 returns, the material taking member 6 deflects and opens, and the material taking member 6 moves to the core position, and the material taking end absorbs the core, and then the core is smoothly taken out of the mold 2 through the sliding action of the swinging member 5.

[0025] First, the core sand is injected into the mold 2. Through the working principle of the core shooter, the core sand is quickly formed into a core in the mold 2. After the core is formed, the mold opening and closing mechanism 3 drives the mold 2 to open. At this time, the demolding mechanism 4 starts to work. The swing member 5 slides on the support 40 for the first time to knock off the material column at the entrance of the mold 2, and then the material removal member 6 is moved to the core position again. After the material removal end absorbs the core, the swing member 5 and the material removal member 6 work together to remove the core from the mold 2. Finally, the removed core is placed in a suitable position for subsequent processing.

[0026] Compared with the traditional core shooting machine, the core shooting machine for iron pad casting of the present invention avoids the problem of uneven force and damage of the core caused by manual coring and flipping and falling through the demoulding mechanism 4. The adsorption method of the material taking end can ensure that the core remains stable during the removal process and will not be impacted and damaged by external forces. The flexible movement of the swing part 5 and the material taking part 6 enables the equipment to adapt to cores of different shapes and sizes, thereby improving the versatility of the equipment. The entire demoulding process has a high degree of automation, which greatly reduces labor intensity and improves production efficiency. At the same time, the dimensional accuracy and surface quality of the core are guaranteed, and the scrap rate is reduced.

[0027] Furthermore, the support 40 includes: a base 41, which is arranged on the frame 1; a deflection plate 42, which is hinged to one side of the base 41, the deflection plate 42 has a slide groove 421, and the swing member 5 is slidably arranged in the slide groove 421; a first driving member 43, one end of which is hinged to the base 41, and the other end is hinged to the deflection plate 42, and the first driving member 43 is used to drive the deflection plate 42 to deflect along the base 41 to open or close.

[0028] In the above scheme, the first driving member 43 pushes the deflection plate 42 to deflect relative to the base 41 through telescopic movement according to the command of the control system. When the first driving member 43 is extended, the deflection plate 42 is deflected outward and opened; when the first driving member 43 is shortened, the deflection plate 42 is deflected inward and closed. The slide groove 421 on the deflection plate 42 provides a sliding track for the swing member 5, and the swing member 5 can slide in the slide groove 421 as needed to adjust the position of the material removal member 6. The material removal member 6 absorbs the core, and then removes the core from the mold 2 under the coordinated action of the swing member 5 and the deflection plate 42. The base 41, the deflection plate 42 and the first driving member 43 cooperate with each other to jointly complete the core removal operation of the demolding mechanism 4.

[0029] Furthermore, the slide groove 421 is in an inverted U shape, and the swing member 5 includes: a second driving member 54, which is arranged on the deflection plate 42; a transmission plate 56, one end of which is arranged on the second driving member 54, and the transmission plate 56 has a strip groove 564; a swing rod 510, which has a connecting end 515, and the connecting end 515 is sequentially penetrated and slidably arranged in the strip groove 564 and the slide groove 421; a fixed plate 52, which is arranged on the deflection plate 42; a slider 57, which is slidably arranged on the fixed plate 52, and the slider 57 has a through groove 58, and the swing rod 510 is slidably arranged in the through groove 58.

[0030] In the above scheme, the U-shaped chute 421 can effectively constrain the connecting end 515 of the swing rod 510, ensuring that the swing rod 510 maintains a stable motion trajectory during the sliding process without deviation or shaking. The U-shaped structure can limit the swing rod 510 to slide in a specific plane, avoiding its unnecessary movement in other directions, thereby improving the accuracy and controllability of the movement of the swing member 5. The second driving member 54 is arranged on the deflection plate 42, which is the power source of the swing member 5. The second driving member 54 can adopt a driving device such as a motor and a hydraulic motor, and its function is to provide power to the transmission plate 56 so that it can move. Through the command of the control system, the second driving member 54 can accurately control the movement speed and direction of the transmission plate 56, thereby realizing the motion control of the swing rod 510. One end of the transmission plate 56 is arranged on the second driving member 54, which plays the role of transmitting power. When the second driving member 54 works, it will drive the transmission plate 56 to move. The transmission plate 56 has a strip groove 564, which provides a space for the connection end 515 of the swing rod 510 to move. During the movement of the transmission plate 56, the connection end 515 of the swing rod 510 can slide in the strip groove 564, thereby realizing the swinging movement of the swing rod 510. The swing rod 510 has a connection end 515, which sequentially penetrates and slides in the strip groove 564 and the slide groove 421. When the transmission plate 56 moves, the swing rod 510 will swing accordingly due to the sliding of the connection end 515 in the strip groove 564 and the slide groove 421. This swinging movement can enable the material taking part 6 to better adapt to the cores in different positions, realize the material taking and discharging of the core, and improve the efficiency and accuracy of coring. The fixed plate 52 is in the shape of an elongated strip, and the fixed plate 52 has a high flatness and precision to ensure that the slider 57 can slide smoothly on the fixed plate 52. The slider 57 is slidably disposed on the fixed plate 52, and the slider 57 has a through slot 58, and the swing rod 510 is slidably disposed in the through slot 58. The slider 57 functions to further constrain and guide the movement of the swing rod 510. The through slot 58 allows the swing rod 510 to slide therein, and the sliding of the slider 57 on the fixed plate 52 can adjust the position of the swing rod 510, thereby achieving precise position control of the material picking member 6.

[0031] During operation, the second driving member 54 starts to work according to the command of the control system, driving the transmission plate 56 to move. The strip groove 564 on the transmission plate 56 assists the connecting end 515 of the swing rod 510 to slide, so that the swing rod 510 generates a swinging motion. At the same time, the connecting end 515 of the swing rod 510 slides in the U-shaped slide groove 421 on the deflection plate 42, further limiting the movement direction and trajectory of the swing rod 510. The sliding of the slider 57 on the fixed plate 52 can meet the extension and retraction of the swing rod 510 as needed, so that the material removal member 6 can be accurately aligned with the core. When the swing rod 510 moves, since it slides in the through groove 58 of the slider 57, the slider 57 will also be adjusted accordingly to maintain the constraint and guidance of the swing rod 510. In short, the various components of the swing member 5 cooperate with each other and work in coordination to achieve the precise swing and position adjustment of the material removal member 6, providing a reliable guarantee for the efficient coring operation of the core shooting machine for iron pad casting.

[0032] Furthermore, the material picking member 6 includes: a deflection member 7, which is arranged on the swing rod 510; an adjustment plate 62, which is slidably arranged on the deflection member 7, and the adjustment plate 62 has a plurality of adjustment slots 621, and the plurality of adjustment slots 621 are arranged radially; a material picking rod 63, which has a plurality of material picking rods 63, and the plurality of material picking rods 63 are slidably arranged on the deflection member 7, and each material picking rod 63 has a driven end 631 on its rod body, and the driven end 631 is slidably arranged in the adjustment slot 621; a negative pressure absorber 64, which has a plurality of negative pressure absorbers 64, and each negative pressure absorber 64 is slidably arranged on one end of a material picking rod 63, and the negative pressure absorber 64 is used to absorb the core.

[0033] In the above scheme, the deflection member 7 plays the role of bearing and fixing other components, and can deflect with the movement of the swing rod 510, so as to adjust the angle of the material picking member 6 or realize whether to pick up the material, so as to better adapt to the cores of different positions and shapes. The deflection member 7 has good rigidity and stability, and can withstand various forces generated during the material picking process. The connection method between it and the swing rod 510 is firm and reliable, ensuring that it will not loosen or fall off during the operation. The adjustment plate 62 is slidably arranged on the deflection member 7, and has a plurality of radially arranged adjustment grooves 621. The main function of the adjustment plate 62 is to adjust the position of the material picking rod 63 by sliding, especially the distance between two adjacent material picking rods 63, so as to adapt to cores of different sizes. The radially arranged adjustment grooves 621 enable the material picking rod 63 to be adjusted in multiple directions, so as to adapt to cores of different shapes and sizes. The sliding of the adjustment plate 62 can be carried out by manual or automatic control to achieve precise adjustment of the material picking rod 63. At the same time, the processing accuracy of the adjustment groove 621 should also be high to ensure that the material picking rod 63 slides smoothly and is accurately positioned. There are several material picking rods 63, all of which are slidably arranged on the deflection member 7. The material picking rod 63 is a component that directly contacts and adsorbs the core. Each material picking rod 63 has a driven end 631 on its rod body, and the driven end 631 is slidably arranged in the adjustment groove 621. The number and distribution of the material picking rods 63 can be adjusted according to the size and shape of the core to ensure that the core can be firmly adsorbed. The surface of the material picking rod 63 should be smooth to avoid damage to the core during the process of adsorbing and removing the core. The cooperation between the driven end 631 and the adjustment groove 621 enables the material picking rod 63 to adjust its position and angle as the adjustment plate 62 slides, so that the material picking rod 63 can more flexibly adapt to cores of different shapes, thereby improving the efficiency and accuracy of material picking. There are several negative pressure absorbers 64, each of which is slidably arranged at one end of a material picking rod 63. The negative pressure absorber 64 is a key component of the material picking part 6 to realize the adsorption of the core. The negative pressure absorber 64 absorbs the core by generating negative pressure, and its adsorption force should be large enough to ensure that the core will not fall off during the material picking and transportation process. The sliding setting of the negative pressure absorber 64 enables it to be adjusted according to the surface shape of the core to ensure the firmness and stability of the adsorption. The working principle of the negative pressure absorber 64 can be to extract air through a vacuum pump or other negative pressure generating device to form a negative pressure environment, thereby adsorbing the core. The radial adjustment groove 621 on the adjustment plate 62 guides the driven end 631 of the material picking rod 63 to slide, so that the material picking rod 63 can be adjusted in different directions. When the material picking rod 63 is adjusted to a suitable position, the negative pressure absorber 64 starts to work and generates negative pressure to adsorb the core. The sliding setting of the negative pressure absorber 64 enables it to be fine-tuned according to the surface shape of the core to ensure the firmness of the adsorption.As the swing rod 510 moves, the deflection member 7 drives the material picking member 6 to deflect, adjusts the angle of the material picking member 6, and enables the material picking member 6 to better adapt to the position of the core. During the material picking and transportation process, the material picking rod 63 and the negative pressure absorber 64 always maintain a firm absorption of the core to ensure that the core is not damaged.

[0034] Furthermore, the deflection member 7 includes: a fixed rod 71, which is arranged on the swing rod 510; a column 72, which is arranged parallel to the fixed rod 71, and the column 72 is slidably arranged on the outer circumference of the fixed rod 71, and each material picking rod 63 is slidably connected to the fixed rod 71 and the column 72 respectively, and the sliding direction of the material picking rod 63 is parallel to the axial direction of the fixed rod 71 and the column 72; a third driving member 75, which is arranged at the top of the fixed rod 71, and the third driving member 75 is used to drive the column 72 to rotate along the axis of the fixed rod 71.

[0035] In the above scheme, during the working process, the material picking rod 63 is slidably adjusted according to the shape and size of the core to ensure that the core can be firmly adsorbed. Under the action of the third driving member 75, the column 72 rotates around the fixed rod 71, thereby driving the material picking rod 63 to adjust the angle. The fixed rod 71 serves as a supporting structure and provides a stable installation foundation for the column 72 and the material picking rod 63. The sliding and rotation of the column 72 cooperate with the sliding of the material picking rod 63 to achieve the position and angle adjustment of the material picking rod 63 in different directions. Through the precise control of the third driving member 75, the column 72 can be rotated quickly and accurately, so that the material picking rod 63 can quickly adapt to different work requirements. During the material picking and transportation process, the material picking rod 63 always maintains a firm adsorption of the core to ensure that the core will not be damaged.

[0036] Furthermore, the adjustment plate 62 has a slide 622, and also includes: a plurality of fixed blocks 65, which are respectively arranged at the two ends of the column 72, and the fixed blocks 65 are hinged to the ends of the fixed rod 71, and the fixed blocks 65 are slidably arranged in the slide 622; a fastening bolt 66 is arranged through the adjustment plate 62 and the fixed block 65, and after the adjustment of the adjustment plate 62 is completed, the fastening bolt 66 is used to fix the adjustment plate 62 on the fixed block 65.

[0037] In the above scheme, when the position of the material picking rod 63 needs to be adjusted, the position of the adjustment plate 62 can be adjusted by moving the position of the fixing block 65 in the slideway 622. The fixing block 65 slides at the two ends of the column 72, driving the adjustment plate 62 to move, thereby changing the position of the material picking rod 63. After the adjustment plate 62 is adjusted to a suitable position, the adjustment plate 62 is fixed to the fixing block 65 by tightening the fastening bolts 66. At this time, the position of the adjustment plate 62 is fixed, and the position and angle of the material picking rod 63 are also determined accordingly. In the process of the rotation of the column 72 and the operation of the material picking rod 63, the fixing block 65 and the fastening bolts 66 can ensure the stability of the adjustment plate 62, thereby ensuring that the material picking rod 63 can accurately adsorb the core.

[0038] Furthermore, the third driving member 75 includes: a driving motor 73, which is arranged at the top of the fixed rod 71, a gear assembly 75, the fixed rod 71 and the column 72 are both arranged on the gear assembly 75, the gear assembly 75 is connected to the driving motor 73 in transmission, and the gear assembly 75 includes a first driving gear, which is arranged on the driving motor 73; a second driving gear, which is arranged on the column 72, and the second driving gear and the first driving gear are meshed for transmission.

[0039] In the above scheme, during the working process, the driving motor 73 is started to drive the first driving gear to rotate. The first driving gear is meshed with the second driving gear to transmit power to the second driving gear. The second driving gear drives the column 72 to rotate around the fixed rod 71. By controlling the speed and direction of the driving motor 73, the rotation angle and speed of the column 72 can be accurately controlled. This gear transmission method has the advantages of high transmission efficiency, high precision, and high reliability, and can meet the requirements of the core shooting machine for iron plate casting for adjusting the angle of the material picking part 6.

[0040] Furthermore, it also includes: a convex plate 53, which is arranged on the top of the swing rod 510, and the convex plate 53 has a bent protrusion 55, and the bent protrusion 55 is used to clean up the scraps on the top of the core.

[0041] In the above scheme, during the casting process of the iron pad, some scraps may remain on the top of the core, and the scraps are the material column of the core. If these scraps are not cleaned up in time, they may affect the quality and subsequent processing of the iron pad. The bending protrusion 55 of the convex plate 53 can contact the scraps on the top of the core and clean them up as the swing rod 510 moves during the material collection process. The bending protrusion 55 can quickly and effectively clean the scraps to the outside of the mold 2. It can remove the scraps from the top of the core by scraping, pushing, etc., to ensure that the surface of the core is clean.
