Large Small injection molding machine How to adjust the levelness of guide rail? Today, Liansheng injection molding machine manufacturer will briefly share with you:

Adjustment scheme for levelness of guide rail of small injection molding machine:

The final judgment standard of whether the levelness adjustment of the machine is qualified is that the mold can be adjusted smoothly when the working oil pressure is not more than 7Mpa; The formwork can be moved smoothly when the working oil pressure is no more than 3Mpa. Please adjust according to the following steps:

(1) Confirm that the machine is located at the position with small die thickness of zui; Install the adjustable washer according to the mounting hole of the main body. The number is usually 6 or 12.

(2) Place the level horizontally on the steel strip or quenching track at the mechanical operation side, between the movable formwork and the adjustable formwork, and close to the movable formwork as far as possible.

(3) Rough adjustment: adjust the adjustable sizing block on the operating side of the machine so that the bubbles are roughly in the center; In addition, place the level horizontally at the same position as the reverse operation side of the machine, adjust the adjustable sizing block on this side, so that the bubble is roughly in the center; Rotate the level by 90 degrees, and place it directly on the steel strip or quenching track at the front and back operation sides of the machine, so that the bubbles are roughly centered. The operation method is the same as above.

(4) Fine adjustment: repeat several times, the horizontal level is about 0.5mm/m, and the longitudinal level is about 0.5mm/m.

(5) The mold adjustment and mold movement shall be carried out according to the above evaluation criteria. If the requirements are met, the horizontal adjustment is qualified.

Adjustment of guide rail levelness of large injection molding machine:

(1) Before installing the machine, first clean the foundation, lift the parts from the ground for 500 mm steadily, and hold the flat washer, spring washer and nut with the anchor bolt passing from bottom to top. Rotate the nut to make the bolt end face 3 times higher than the nut upper end face.

(2) Put the machine on the sizing block, confirm that the position of the foundation bolt of the machine body is inconsistent with the reserved hole, close the injection molding part and the mold closing part according to the above method, and then carry out horizontal rough calibration according to the regulation rules.

(3) After confirming the liquid level with a liquid level meter, inject concrete into the reserved holes of the foundation and fix the foundation bolts.

(4) After a period of maintenance, confirm that the poured concrete has solidified (the maintenance period in summer is about ten days, and the maintenance period in winter is about fifteen days). Then adjust the level of the machine body according to the adjustment. After the level is confirmed by the level meter, tighten the anchor bolts and nuts with a lever to fix the machine.
