[0025] Includes: a side core-pulling assembly 01, which includes a fixed mold 11. A wedge 12 is fixedly installed on one side of the fixed mold 11. The wedge 12 can limit the slider 13 to ensure that the slider 13 can reach the designated position without affecting the mold forming. The slider 13 is abutted below the fixed mold 11. A base plate 14 is fixedly installed below the slider 13. A fixing plate 15 is fixedly installed on one side of the base plate 14. A return spring 16 is provided inside the fixing plate 15. The return spring 16 plays the role of reset. A lubrication assembly 03 is provided inside the fixed mold 11. An adjustment assembly 02 is provided inside the wedge 12.
[0026] Adjustment component 02 includes a lead screw 21. Moving the lead screw 21 can drive the guide rod 25 to move, which in turn drives the abutment plate 26 to move. A nut pair 22 is connected to the outer wall of one end of the lead screw 21. A rudder 23 is fixedly installed on the outer wall of the nut pair 22. A fixing ring 24 is inserted inside the rudder 23, and the fixing ring 24 guides the rudder 23. The guide rod 25 is fixedly connected to the end of the lead screw 21 away from the nut pair 22. The guide rod 25 guides the movement of the abutment plate 26, which abuts the slider 13 to the designated position to prevent the slider 13 from deviating from its position. The abutment plate 26 is fixedly installed on the side of the guide rod 25 away from the lead screw 21.
[0027] Furthermore, the lubrication assembly 03 includes an inclined guide post 31, with a plug 32 inserted above the inclined guide post 31. A stop block 33 is provided on the inner side below the inclined guide post 31, and a protrusion 34 is fixedly installed on one side of the stop block 33. When the protrusion 34 is pressed by the slider 13, the protrusion 34 presses against the stop block 33, the ordinary spring 35 is compressed, and the stop block 33 no longer presses against the oil hole in the inclined guide post 31. The lubricating oil in the inclined guide post 31 flows down into the slider 13, facilitating lubrication of the inclined guide post 31. Quick and easy. The stop block 33 is connected to the inclined guide post 31 by a common spring 35. The common spring 35 provides elastic force. When the slider 13 no longer presses against the protrusion 34, the stop block 33 moves under the elastic force of the common spring 35 and presses against the oil hole of the inclined guide post 31. The stop block 33 and the inclined guide post 31 are in a sliding connection. The stop block 33 moves into the inclined guide post 31 and no longer presses against the oil hole of the inclined guide post 31. The lubricating oil can flow into the slider 13, which is convenient for lubricating the inclined guide post 31. It is simple and quick.
[0028] Furthermore, the lead screw 21 is slidably connected to the wedge 12. The movement of the lead screw 21 can drive the guide rod 25 to move, which in turn drives the abutment plate 26 to move. The rudder 23 is rotatably connected to the fixed ring 24, and the fixed ring 24 plays a guiding role for the rudder 23.
[0029] Furthermore, the fixing ring 24 is fixedly connected to the wedge 12 to ensure the stability of the fixing ring 24. The guide rod 25 is slidably connected to the wedge 12. The guide rod 25 plays a guiding role. The movement of the guide rod 25 can drive the abutment plate 26 to move, so that the slider 13 is abutted at the designated position to avoid deviation of the slider 13 position.
[0030] Furthermore, the inclined guide post 31 is fixedly connected to the fixed mold 11 to ensure the stability of the inclined guide post 31. The plug 32 has a vent hole inside to ensure that the lubricating oil in the inclined guide post 31 can flow smoothly into the slider 13.
[0031] Furthermore, the two ends of the ordinary spring 35 are fixedly connected to the inclined guide post 31 and the stop block 33 respectively. The ordinary spring 35 provides elastic force. When the slider 13 no longer presses against the protrusion 34, the stop block 33 moves under the elastic force of the ordinary spring 35 and presses against the oil hole of the inclined guide post 31. The stop block 33 is slidably connected to the inclined guide post 31. The stop block 33 moves into the inclined guide post 31 and no longer presses against the oil hole of the inclined guide post 31. The lubricating oil can flow into the slider 13, which is convenient for lubricating the inclined guide post 31. It is simple and quick.
[0032] Furthermore, the inclined guide post 31 has an oil hole inside, and the oil hole is located on the upper surface of the block 33. When the protrusion 34 is pressed by the slider 13, the protrusion 34 presses the block 33, the ordinary spring 35 is compressed, and the block 33 no longer presses against the oil hole in the inclined guide post 31. The lubricating oil in the inclined guide post 31 flows down into the slider 13, which facilitates the lubrication of the inclined guide post 31 in a simple and quick manner.
[0033] Working principle: First, open the plug 32, add lubricating oil to the inclined guide post 31, and then plug the plug 32 back in. When the inclined guide post 31 moves within the slider 13, the slider 13 presses against the protrusion 34, pushing the protrusion 34 into the inclined guide post 31. The protrusion 34 presses against the stop block 33, compressing the ordinary spring 35. The stop block 33 no longer presses against the oil hole in the inclined guide post 31, and the lubricating oil in the inclined guide post 31 flows down into the slider 13. When wear occurs on the contact surface between the abutment plate 26 and the slider 13, the rudder 23 can be rotated. The rudder 23 drives the nut pair 22 to rotate, the nut pair 22 drives the lead screw 21 to move, the lead screw 21 drives the guide rod 25 to move, and the guide rod 25 drives the abutment plate 26 to move, allowing the abutment plate 26 to abut the slider 13 at the designated position. The above is the complete working principle of this utility model.
