When the lifting plate 6 moves upward and drives the top block 8 to move upward, the sliding block 12 at the bottom of the connecting rod 9 can be displaced in the sliding groove 11, while ensuring the connection with the top block 8 without affecting the displacement of the top block 8, and ensuring the linkage effect of the top block 8 and the lifting plate 6.

[0039] The lower end of the push rod 7 is provided with a mounting groove upward, and the upper end of the mounting groove is provided with a plurality of air outlet holes 21 distributed in an annular shape, and an air cavity 22 is provided inside the mounting groove, and air is contained in the air cavity 22, and an axially movable push rod 14 is slidably connected inside the mounting groove, and the bottom of the push rod 14 is respectively fixedly connected to the lifting plate 6, and the upper end of the push rod 14 is fixedly connected with an air-thrusting piston 13, and the air-thrusting piston 13 is respectively slidably matched with the inside of the air cavity 22, and when the push rod 14 moves axially, the air-thrusting piston 13 can be pushed to move in the air cavity 22, so as to achieve the effect of pumping and pushing air, and the bottom of the push rod 7 is respectively fixedly connected with a baffle plate 16, and the surface of the push rod 14 on the lower side of the baffle plate 16 is respectively sleeved with The support spring 15 drives the push rod 14 to move upward when the lifting plate 6 moves upward, and then pushes the push rod 7 to move upward through the support spring 15. After the baffle 16 is pressed against the bottom of the molding mold 2, the lifting plate 6 will squeeze the support spring 15 when it continues to move upward, and when the push rod 14 moves upward, it can push the push piston 13 to move axially in the air cavity 22 and push the gas in the air cavity 22 out.

When the lifting plate 6 moves downward, it can drive the push rod 14 and the push rod 7 to reset, and when the push rod 14 moves downward and resets, it drives the push piston 13 to reset and re-inhale the gas.

[0040] Furthermore, in order to improve the production quality of the guard plate and prevent the push rod 7 from affecting the quality of the guard plate, a spring groove is provided inside the push rod 7 on the upper side of the air cavity 22, and a groove 50 is provided downwardly at the upper end of the push rod 7. A connecting hole is provided in the middle of the groove 50, and the connecting hole is downwardly opened to connect the spring groove and the air cavity 22.

The return spring 19 presses against the upper end of the spring plate and uses its own elastic force to provide resistance to the upward movement of the closing plate 18. When the gas inside the air cavity 22 is compressed, the driving force generated can overcome the elastic force of the return spring 19, and the closing plate 18 moves upward to push the gas out. A one-way air intake valve is fixedly connected to the surface of the air cavity 22, and the one-way air intake valve air cavity 22 is connected to the outside. In the process of pushing the piston downward to move and reset, the closing plate 18 is reset under the push of the return spring 19, and the gas can enter the air cavity 22 through the one-way air intake valve to replenish the air in the air cavity 22.

[0041] The front and rear sides of the right end of the shaping mold 1 are respectively fixedly connected with mounting plates 28, and the mounting plates 28 are respectively slidably connected to the shaping mold 2. A horizontal plate is fixedly connected to the lower side of the two mounting plates 28, and a first pin shaft 29 is fixedly connected to the right end of the horizontal plate.

The inclined groove of the first guide groove 26 is a structure with a front end inclined downward and is on the front side of the transverse groove, and the inclined groove of the second guide groove 27 is a structure with an upper end inclined upward and is on the rear side of the transverse groove. When the guide plate 24 moves, the first guide groove 26 and the second guide groove 27 can first drive the molding mold to move upward through the sliding cooperation with the first pin shaft 29 and the second pin shaft 30 respectively, and then drive the lifting plate 6 to move upward. When the guide plate 24 is reset, it can first drive the lifting plate 6 to move downward and reset, and then drive the molding mold 1 to move downward and reset.

[0043] The operating arm includes a support plate 37 and a displacement plate 36 slidably connected to the support plate 37 and capable of moving up and down. A push spring 38 is fixedly connected between the displacement plate 36 and the support plate 37. The left and right sides of the rear end of the displacement plate 36 are respectively fixedly connected with connecting shafts 55. The rear ends of the connecting shafts 55 are respectively connected to the suction cups 31. The front end of the shaping mold 2 is fixedly connected with a second hydraulic telescopic rod 42.

The second hydraulic telescopic rod 42 is used to drive the operating arm to move left and right. When the operating arm moves to the left, the blocking rod 39 can be used. The rod 39 is pressed against the inclined surface of the inclined surface block 40, and then the downward push is generated under the action of the sliding cooperation between the blocking rod 39 and the inclined surface, pushing the displacement plate 36 to move downward. When the displacement plate 36 moves downward, it will squeeze the push spring 38, and when the displacement plate 36 moves downward, the suction cup 31 is driven downward through the connecting shaft 55 to move the formed guard plate, which is provided with a limit frame 54 in the direction of movement of the support plate 37. When the support plate 37 moves to the right, it slides with the inner wall of the limit frame 54, and the support plate 37 is limited by the limit frame 54 so that the support plate 37 can move stably, and then when the second hydraulic telescopic rod 42 moves in the opposite direction, the guard plate is driven to fall off the mold, which is convenient for removing the guard plate and avoiding manual operation. After the inclined surface block 40 is disengaged from the blocking rod 39, the displacement plate 36 is reset under the push of the push spring 38.

[0044] Furthermore, in order to improve the adsorption force of the suction cup 31, the upper end of the suction cup 31 is fixedly connected and connected to the mounting tube 32, and the interior of the mounting tube 32 is slidably matched with a suction piston 33, and the upper ends of the suction pistons 33 are respectively fixedly connected to operating plates 53, and the front ends of the operating plates 53 are respectively vertically slidably connected to the upper ends of the support plates 37, and the rear ends of the connecting shafts 55 are respectively fixedly connected to connecting plates 35, and the connecting plates 35 are respectively spline-connected to the mounting tube 32, and the surfaces of the mounting tube 32 on the lower sides of the connecting plates 35 are respectively sleeved with connecting springs. 34. When the displacement plate 36 moves downward, the connecting plate 35 can be driven to move downward through the connecting shaft 55, and the suction cup 31 is pushed downward to adsorb the guard plate while squeezing the connecting spring 34. After the suction cup 31 is squeezed on the surface of the guard plate, the air inside is squeezed out, and a negative pressure is generated inside the suction cup 31 to maintain the adsorption effect of the suction cup 31. When the guard plate needs to be removed, it is only necessary to press the operating plate 53 downward. When the operating plate 53 moves downward, it can drive the vacuum piston 33 to move downward to generate a thrust to push the guard plate away from the suction cup 31.

After the strong magnetic sphere 52 is engaged in the groove 50, the operating panel 53 is fixed by the mutual attraction between the magnetic block and the strong magnetic sphere 52, thereby the suction piston 3 is pressed. 3 is fixed, so that the air extraction piston 33 cannot move downward under the attraction of the suction cup 31. When the operating arm moves to the outside, the matching gear 41 meshes with the moving rack 43, and then drives the support plate 37 to rotate under the meshing of the moving rack 43. During the rotation of the support plate 37, the strong magnetic sphere 52 is separated from the groove 50, and the operating plate 53 is pushed downward by the bottom of the stop plate 49, so that the air extraction piston 33 moves downward to produce a pushing effect.
