along with the operation of a first motor 15, a driving gear 12 starts to rotate, a transmission belt 13 is in transmission connection with the driving gear 12, the transmission belt 13 starts to rotate, a transmission gear 11 is in transmission connection with the transmission belt 13, the transmission gear 11 starts to rotate, a screw rod 9 is fixedly inserted in the middle of the transmission gear 11 coaxially, the rotation of the transmission gear 11 can drive the screw rod 9 to rotate, a slide block 8 is in threaded connection with the screw rod 9, the rotation of the screw rod 9 drives the slide block 8 to move in the horizontal direction, the slide block 8 is in sliding connection with a limit sliding table 10, the slide block 8 can move inside the limit sliding table 10, the limit sliding table 10 provides limit for the movement of the slide block 8 and ensures that the movement process of the slide block 8 is stable, one end, provided with a shaft hole, of a draw bar 7 is hinged to the slide block 8, the movement of the slide block 8 drives the draw bar 7 to move, the draw bar 7 is fixedly connected with the side wall of a lower die 4, the draw bar 7 drives the lower die 4 to move in the horizontal direction, the draw bar 7 is lifted up by lifting of the connecting rod 14, and the support base 7 can move in the vertical direction and the support base 4 and finally changes the movement route of the lower die 4 into a vertical movement route.
Move the in-process at lower mould 4, go up mould 17 through four gag lever posts 48 settings in the upper end of lower mould 4, along with lower mould 4 removes, go up mould 17 and also carry out the ascending arc displacement of vertical side and accomplish 90 upset, go up mould 17 and lower mould 4 this moment and need separate, specific separation process is: along with the movement of the upper die 17, the lower end of the transmission connecting rod 22 slides along the vertical limiting groove 20 in the second limiting slide seat 21, at the same time, the upper end of the transmission connecting rod 22 slides along the horizontal limiting groove 19 in the first limiting slide seat 18, during the process that the upper die 17 is turned to 90 degrees, the lower end of the transmission connecting rod 22 is abutted against the end part of the vertical limiting groove 20 in the second limiting slide seat 21, the upper end is abutted against the end part of the horizontal limiting groove 19 in the first limiting slide seat 18, at the same time, the upper end of the transmission connecting rod 22 is hinged with the first limiting pin 23, the lower end is hinged with the second limiting pin 24, along with the continuous movement of the lower die 4, the upper die 17 is limited and stopped moving by the transmission connecting rod 22, namely, the separation of the upper die 17 from the lower die 4 is completed, during the separation, the four limiting rods 48 can ensure that the movement of the upper die 4 and the lower die 4 does not generate play, the four limit rods 48 can also connect the upper die 17 and the lower die 4, so that the upper die 17 can move along the direction of the limit rods 48 when the upper die 17 is separated from the lower die 4, because the cast sand exists in the upper die 17, the upper die 17 and the lower die 4 can not be separated by virtue of the tension of the transmission connecting rod 22, when the transmission connecting rod 22 moves and the upper die 17 is separated from the lower die 4, one end of the elastic steel strip 28 is hinged with the positioning buckle 29 arranged at the fixed support 30, the other end of the elastic steel strip 28 is hinged with the positioning buckle 29 arranged at the anti-falling gasket 25, and the elastic steel strip 28 is stretched along with the separation of the upper die 17 and the lower die 4, at the moment, because the elastic steel strip 28 needs to be reset, the elastic force generated during resetting can drag the upper die 17, and the reset elastic force provides auxiliary force for the upper die 17, so that the upper die 17 can be separated from the lower die 4 more easily. After the casting is finished by the device, the elastic steel belt 28 can also drive the transmission connecting rod 22 to reset, so that the device runs smoothly.
When the lifting connecting rods 14 move, arc displacement is carried out along the vertical direction along with the lifting connecting rods 14, one end of each first linkage rod 32 is hinged to the middle portions of the two lifting connecting rods 14, the other end of each first linkage rod 32 is hinged to the middle portion of each second linkage rod 33 in a sliding mode through a bolt, arc displacement is carried out along with the movement of the lifting connecting rods 14 along with the first linkage rods 32, each second linkage rod 33 is connected with the corresponding first linkage rod 32, one end of each second linkage rod 33 is hinged to the side wall of the supporting seat 5, the linkage rods move along with the first linkage rods 32, and arc displacement can be carried out along the vertical direction along with the ends, connected with the bearing platforms 35, of the second linkage rods 33. Along with the arc displacement is carried out along the vertical direction to second trace 33, load-bearing platform 35 and second trace 33 fixed connection, load-bearing platform 35 can carry out the arc displacement along the vertical direction, cylinder frame 36 and second load-bearing platform 35 fixed connection, cylinder frame 36 can carry out the arc displacement along the vertical direction, four extension pipe casings 37 and cylinder frame 36 fixed connection, four extension pipe casings 37 can carry out the arc displacement along the vertical direction, four die clamping cylinder 38 set up the tip at four extension pipe casings 37, four die clamping cylinder 38 can carry out the arc displacement along the vertical direction, finally four die clamping cylinder 38 can support four lateral walls departments at last mould 17, four die clamping cylinder 38 operation this moment, die clamping cylinder 38's arm lock can press from both sides last mould 17 tightly. When the blade 41 cuts a casting head of a casting, the casting can generate a reaction force on the blade 41, the four clamping cylinders 38 clamp the upper die 17 to prevent the bearing platform 35 from moving due to the reaction force, the four clamping cylinders 38 improve that when the four clamping cylinders 38 clamp the upper die 17, the second motor 44 runs, the first bevel gear 45 is fixedly connected with the output end of the second motor 44, the second motor 44 runs to drive the first bevel gear 45 to rotate, the second bevel gear 46 is meshed with the first bevel gear 45, the first bevel gear 45 rotates to drive the second bevel gear 46 to rotate, the positioning pin 47 is coaxially and fixedly inserted in the second bevel gear 46, the second bevel gear 46 rotates to drive the positioning pin 47 to rotate, the tool rest 40 is fixedly sleeved outside the positioning pin 47, the positioning pin 47 rotates to drive the tool rest 40 to rotate, the two blades 41 are fixedly arranged on two sides of the tool rest 40, the tool rest 40 rotates to drive the blades 41 to rotate, and the blade 41 can cut the casting head of the casting when the blade 41 rotates. When the blade 41 cuts the casting head of the casting, the cutting teeth 42 formed on the blade 41 are distributed in an inclined shape, compared with the cutting edge of a traditional cutting tool, the blade 41 formed with the cutting teeth 42 has a better processing effect on the casting head of the casting, and because the cutting work is completed in the casting sand, the through holes 43 on the blade 41 are beneficial to the broken casting sand to flow through the blade 41 better, the friction force between the blade 41 and the casting sand is reduced, and the cutting efficiency is increased. The four limiting insertion rods 49 can penetrate through the upper die 17 and then are fixedly connected with the liquid injection pipe 1, so that when the blade 41 is used for cutting a casting head, the liquid injection pipe 1 cannot fall off from the upper die 17 along with the scattering of casting sand, and the running stability of the device is improved. And the castings after cutting are cut off due to the casting head, the castings which are not fallen off at this time can fall off from the upper die 17 at this time when the subsequent upper die 17 is reset to the horizontal state, the castings fall off to the upper end of the supporting seat 5 from the upper side of the supporting seat 5, and an operator can collect the castings only by using a tool such as a dustpan or a collecting frame.
